Electromagnetic clutch system

Introduction:

Clutch:

Clutch is basically a mechanism which is being used for transmitting rotation, which can be engaged and disengaged. Clutches are being used particularly in those devices that have two rotating shafts. In these devices, one shaft is typically driven by a motor or pulley, and the second drives the another device. The clutch connects the two shafts so that they can either be locked together and spin at the same speed, or be decoupled and spin at different speeds.

The clutch disc(center) spins with the fly wheel (left). To disengage, the lever is pulled, causing a white pressure plate to disengage the green clutch disc from turning the drive shaft, which turns within the thrust bearing ring of the lever. All the 3 rings will never connect, with any gaps.

Requirement of a clutch:

Torque transmission: The clutch should be able to transmit maximum torque of
the engine.

Gradual engagement: The clutch should engage gradually to avoid sudden jerks.

Heat dissipation: The clutch should be able to dissipate large amount of heat
which is generated during the clutch operation due to friction.

Dynamic balancing: The clutch should be dynamically balanced. This is
particularly required in the case of high speed engine clutches.

Vibrating damping: The clutch should have suitable mechanism to damp
vibrations and to eliminate noise produced during the power transmission.

Size:- The clutch should be as small as possible in size so that it will occupy
minimum space.

Free pedal play: The clutch should have free pedal play in order to reduce
effective clamping load on the carbon thrust bearing and wear on it.

Easy in operation: The clutch should be easy to operate requiring as little
exertion as possible on the part of the driver.

Lightness: The driven member of the clutch should be made as light as possible
so that it will not continue to rotate for any length of time after the clutch has
been disengaged.

Types of clutches:

Different types of clutches are as follows:
1. Friction clutch:
(a) Single plate clutch
(b) Multi plate clutches:
Wet clutch.

2. Centrifugal clutch.

3. Semi-centrifugal clutch

(b) Crown spring type

5. Positive clutch:
(a) Dog and Spline clutch

6. Hydraulic clutch

7. Electromagnetic clutch

8. Vacuum clutch

9. Over running clutch or free-wheel unit

Main Parts of the clutch:

The main parts of the clutch is divided into three parts :

Driving members:
It consist of a fly wheel mounted on the engine crankshaft.

Flywheel couple with clutch

Driven members:
The driven members are consist of the disc or plate, called the clutch plate.

Pressure plate and clutch plate

Operating members:

Operating members are consist of a foot pedal, linkage, release or throw out bearing, release levers and springs.

Pedal, Bearing and spring

Electromagnetic clutch:

Electromagnetic clutches operate electrically, but transmit torque mechanically. That is why they are called electromechanical clutches. They are most suitable for remote operation since no mechanical linkages are required to control their engagement, providing fast and smoothing operation.

However, because the activation energy dissipates as heat in the electromagnetic actuator when the clutch is engaged, there is a risk of overheating. Consequently, the maximum operating temperature of the clutch is limited by the temperature rating of the insulation of the electromagnet.

In this type of clutch, the flywheel consists of winding from the battery or dynamo.
When the current passes through the winding. it produced an electromagnetic field which attracts the pressure plate.
Thereby engaging the clutch.
When the supply is cut-off the clutch is disengaged.
The gear lever consists of a clutch release switch.
When the driver holds the gear lever to change the gear, the switch is operated
cutting off the current to the winding which causes the clutch disengaged.
At low speed when the dynamo output is low, the clutch is not firmly engaged.
Therefore, three springs are also provided on the pressure plate which helps the
clutch engaged firmly at low speed also.

Construction:

A horseshoe magnet has a north and south pole. If a piece of carbon steel contacts both poles, a magnetic circuit is created. In an electromagnetic clutch, the north and the south pole is create by a coil shell and a wound coil. In a clutch when power is applied, a magnetic field is created in the coil. This field overcomes an air gap between the clutch rotor and the armature. This magnetic attraction, pulls the armature on contact with the rotor face. The frictional contact, which is being control by the strength of the magnetic field, is what causes the rotational motion to start.

The torque comes from the magnetic attraction of the coil and the fiction between the steel of the armature and the steel of the clutch rotor. For many industrial clutches, friction material is used between the poles. The material is mainly used to help to decrease the wear rate, but different types of material can also be used to change the coefficient of friction. For example, if the clutch is required to have an extended time to speed or slip time, a low co efficient of friction material can be used and if a clutch is required to have a slightly higher torque, a high coefficient friction material can be used.

In a clutch, the electromagnetic lines of flux have to pass into the rotor, and in turn, attract and pull the armature in contact with it to complete clutch engagement. Most industrial clutches use what is called a single flux, two pole design. Mobile clutches of other specially electromagnetic clutches can use a double or triple flux motor. The double or triple flux refer to the number of north- south flux paths, in the rotor and the armature.

Basic structure of Electromagnetic Clutch

This means that, if the armature is designed properly and has similar banana slots, what occurs is the leaping of the flux path. Which goes north south, south north. By having more points of contact, the torque can be greatly increased. In theory if there were two sets of poles at the same diameter, the torque would double in the clutch. Obviously, that is not possible to do, so the points of contact have to be at a smaller inner diameter. Also there are magnetic flux losses because of the bridges between the banana slot. But by using a double flux design, a 30- 50%increase in torque can be achieved, and by using a triple flux design, a 40-90% torque can be achieved. This is important in applications where size and weight are critical, such as automotive requirements.

The coil shell is made with the carbon steel that has a combination of good strength and good magnetic properties. Copper magnet wire, is used to create the coil, which is held in shell either by a bobbin or by some type of epoxy.

To increase life in applications, friction material is used between the poles on the face of the rotor. This friction material is flush with the steel on the rotor, since if the friction material was not flush, good magnetic traction could not occur between the faces. Some people look at electromagnetic clutches and mistakenly assume that, since the friction material is flush with the steel that the clutch has already worn down but this is not the case. Clutches used In most mobile applications do not use the friction material. Their cycle requirements tend to be lower than industrial clutches and their cost is more sensitive. Also many mobile clutches are exposed to outside elements, so by not having friction material, it eliminates the possibility of swelling, that can happen when friction material absorbs moisture.

Need of using Electromagnetic Clutch:

Function of clutch is to engage or disengage the engine from the transmission system. Hence it is inserted between the flywheel as well as gear box. It is consists of main important parts like clutch plate, pressure plate, friction disc, operating lever etc. In clutch engage as well as disengage are very important, because due to which clutch is used. But when clutch is applied at that time, some clearance is there in the clutch pedal called clutch pedal play and due to which, proper disengage of clutch is not achieve and clutch will slip or dragged.

There is a need to use some system incorporated in clutch system, to prevent above situation. Hence, if we shift gear and at that time clutch will disengage hence, it is very simple for driver and force require to engage as well as disengage the clutch is also neglected, hence a new type of clutch used in automobile vehicles called “Renault Car” called electromagnetic clutch.

In this clutch system, when gear shift lever is applied at that time, due to MMF clutch will disengage and when release lever, clutch will engage.

Basic operation of electromagnetic clutch:

The clutch has four main parts:

Field Coil
Rotor
Armature
Hub

When we apply the voltage, the stationary magnetic field generates the lines of flux that pass into the door. The flux pulls the armature in contact with the rotor, as the armature and the output start to accelerate. Slipping between the rotor face and the armature face continues until the input and the output speed is the same. The actual time for this is quite short, between 1/200th of a second and 1 second.

Disengagement is very simple. Once the field starts to degrade, flux falls rapidly and the armature separates. One or more springs hold the armature away from the rotor at a predetermined air gap.

Voltage/current and the magnetic field.

If a piece of copper wire was wound, around the nail and then connected to a battery, it would create an electromagnet. The magnetic field that is generated in the wire, from the current, is known as the “right hand thumb rule”. (FIGURE-21) The strength of the magnetic field can be changed by changing both wire size and the amount of wire (turns). EM clutches are similar; they use a copper wire coil (sometimes aluminum) to create a magnetic field.

The fields of EM clutch can be made to operate at almost any DC voltage, and the torque produced by the clutch or brake will be the same, as long as the correct operating voltage and current is used with the correct clutch. If a 90 V clutch, a 48 V clutch and a 24 V clutch, all being powered with their respective voltages and current, all would produce the same amount of torque. However, if a 90 V clutch had 48 V applied to it, this would get about half of the correct torque output of that clutch. This is because voltage/current is almost linear to torque in DC electromagnetic clutches.

A constant power supply is ideal if accurate or maximum torque is required from a clutch. If a non regulated power supply is used, the magnetic flux will degrade, as the resistance of the coil goes up. Basically, the hotter the coil gets the lower the torque will be, by about an average of 8% for every 20°C. If the temperature is fairly constant, but there may not be enough service factor in your design for minor temperature fluctuation. Over-sizing, the clutch would compensate for minor flux. This will allow the use a rectified power supply which is far less expensive than a constant current supply.

Based on V = I × R, as resistance increases available current falls. An increase in resistance, often results from rising temperature as the coil heats up, according to: Rf = Ri × [1 + αCu × (Tf – Ti)] Where Rf = final resistance, Ri = initial resistance, αCu = copper wire’s temperature coefficient of resistance, 0.0039 °C-1, Tf = final temperature, and Ti = initial temperature.

Engagement time:

There are actually two engagement times to consider in an electromagnetic clutch. The first one is the time that it takes for a coil to develop a magnetic field, strong enough to pull in an armature. Within this, there are two factors to consider. The first one is the amount of ampere turns in a coil, which will determine the strength of a magnetic field. The second one is air gap, which is the space between the armature and the rotor. Magnetic lines of flux diminish quickly in the air.. Air gap is an important consideration especially with a fixed armature design because as the unit wears over many cycles of engagement the armature and the rotor will create a larger air gap which will change the engagement time of the clutch. In high cycle applications, where registration is important, even the difference of 10 to 15 milliseconds can make a difference, in registration of a machine. Even in a normal cycle application, this is important because a new machine that has accurate timing can eventually see a “drift” in its accuracy as the machine gets older.

The second factor in figuring out response time of a clutch is actually much more important than the magnet wire or the air gap. It involves calculating the amount of inertia that the clutch needs to accelerate. This is referred to as “time to speed”. In reality, this is what the end-user is most concerned with. Once it is known how much inertia is present for the clutch to start then the torque can be calculated and the appropriate size of clutch can be chosen.

Most CAD systems can automatically calculate component inertia, but the key to sizing a clutch is calculating how much inertial is reflected back to the clutch or brake. To do this, engineers use the formula: T = (wk2 × ΔN) / (308 × t) Where T = required torque in lb-ft, WK2 = total inertia in lb-ft2, ΔN = change in the rotational speed in rpm, and t = time during which the acceleration or deceleration must take place.

There are also online sites that can help confirm how much torque is required to accelerate a given amount of inertia over a specific time.

Elements of the Electromagnetic clutch:

Electromagnetic clutches share basic structural components: A coil in a shell, also refereed to as a field: a hub: and an armature. A clutch also has a rotor, which connects to the moving part of the machine, such as drive shaft.

The coil shell is usually carbon steel, which combines strength with magnetic properties.
Copper wire forms the coil, although sometimes aluminum is used. A bobbin or epoxy adhesive holds the coil in the shell.

Activating the unit’s electric circuit energizes the coil. The current running through the coil generates a magnetic field. When magnetic flux overcomes the air gap between the armature and field, magnetic attraction pulls the armature – which connects to the hub -into contact with the rotor.

Magnetic and friction forces accelerate the armature and hub to match rotor speed. The rotor and the armature slip past each other for the first 0.02 to 1.0 seconds until the input and the output speeds are the same. The matching of the speed is sometimes called 100% lockup.

Working of Electromagnetic clutch:

The main components of EM clutch are a coil shell, an armature, rotor, and hub. The armature plate is lined with friction coating. The coil is placed behind the rotor. When the clutch activated the electric circuit energizes the coil, it generates a magnetic field. The rotor portion of clutch gets magnetized. When the magnetic field exceeds the air gap between rotor and armature and then it pulls the armature toward the rotor. The frictional force generated at the contact surface transfer the torque. Engagement time depends on the strength of magnetic fields, inertia, and air gap. When voltage is removed from the coil, the contact is gone. In most design a spring is used to hold back the armature to provide an air gap when current is removed.

Application of electromagnetic clutch:

They can be used for remote application because they do not require linkage to actuate the clutch. They are used in printing machinery, conveyor drives, copier machines and factory automation. In an automobile, it replaces clutch pedal by a simple switch button. A smaller EM clutch is used to drive the compressor of air conditioning system.

The complicated linkage is not required to control clutch.

FABRICATION OF SOLAR OPERATED WOOD CUTTER

SYNOPSIS:-

This is the new innovative and effective concept mainly used for wood cutting field. It is simple in construction and the working process is very easy. And it is mostly used in the timber field for the cutting of wood, trees, wooden pieces and etc.., The project aims at designing a system which makes the Wood cutter based motor running through solar energy.

INTRODUCTION:-

Power plays a great role wherever man lives and works. The living standard and prosperity of a nation vary directly with the increase in the use of power. The electricity requirement of the world is increasing at an alarming rate due to industrial growth, increased and extensive use of electrical gadgets. According to world energy report, we get around 80% of our energy from conventional fossil fuels like oil (36%), natural gas (21%) and coal (23%). It is well known that the time is not so far when all these sources will be completely exhausted. So, alternative sources should be used to avoid energy crisis in the nearby future. The best alternative source is solar energy. A solar panel is a large flat rectangle, typically somewhere between the size of a radiator and the size of a door, made up of many individual solar energy collectors called solar cells covered with a protective sheet of glass. The cells, each of which is about the size of an adult’s palm, are usually octagonal and colored bluish black. Just like the cells in a battery, the cells in a solar panel are designed to generate electricity; but where a battery’s cells make electricity from chemicals, a solar panel’s cells generate power by capturing sunlight instead. They are sometimes called photovoltaic cells because they use sunlight (“photo” comes from the Greek word for light) to make electricity (the word “voltaic” is a reference to electricity pioneer Alessandro Volta). The system depending on the charging circuit the motor can be controlled. The solar power stores the energy to a battery and then runs the motor.

Introduction:

Is anyone happy with the current situation of electricity in india? So this is our small step to try to improve this situation by our project. An energy crisis is any great bottleneck (or price rise) in the supply of energy resources to an economy. It usually refers to the shortage of oil and additionally to electricity or other natural resources. An energy crisis may be referred to as an oil crisis, petroleum crisis, energy shortage, electricity shortage electricity crisis. Some days before we had seen a torch which lights up when a mechanical force is applied on it by our hand. The basic principle what we noticed in this is conversion of mechanical energy to electrical energy. So our project is to generate electricity from the speed breakers by the applying the same principle. We are trying to use the mechanical stress which is applied on the speed breaker to the electric current. By this approach we can able to use unuseful mechanical stress for the useful purpose. And thus we can use this generated electricity to lights up villages near highway. “next time on the road, don’t scoff at the speed breakers. They could actually light up small villages off the highway

How the speed breaker are useful for thegeneration of ELECTRICITY?

Next time on the roads, don’t scoff at the speed-breakers. They could actually light up small villages off the highway.

An amateur innovator in Guwahati has developed a simple contraption that can generate power when a vehicle passes over a speed breaker. Kankan Gogol, a small time businessman, has developed a mechanism to generate power by converting the potential energy generated by a vehicle going up on a speed breaker into kinetic energy. The innovation has caught the eye of the Indian Institute of Technology (IIT), Guwahati, which will fund a pilot project to generate electricity from speed-breakers.

The idea is basic physics. Gogol has welded five-metre-long metal plates into the speed-breaker instead of the conventional bitumen-and-stone-chip rumble strip. The plates are movable and inclined with the help of a spring-loaded hydraulic system. The fulcrum-attached plates are pushed down when a vehicle moves over them and bounce back to original position as it passes.

“When the vehicle moves over the inclined plates, it gains height resulting in increase in potential energy, which is wasted in a conventional rumble strip,” Gogol says. “When the plates come down, they crank a lever fitted to a ratchet-wheel type mechanism. This in turn rotates a geared shaft loaded with recoil springs. The output of this shaft is coupled to a dynamo to convert kinetic energy into electricity,” he explains.

IIt Guwahati has evaluated the machine and recommended it to the Assam ministry of power for large scale funding. A K Das, a professor at IIt’s design department says it is a ‘very viable proposition’ to harness thousands of mega watts of electricity untapped across the country every day.

“A vehicle weighing 1,000 kg going up a height of 10 cm on such a rumble strip produces approximately 0.98 kilowatt power. So one such speed-breaker on a busy highway, where about 100 vehicles pass every minute, about one kilo watt of electricity can be produced every single minute. The figure will be huge at the end of the day,” he said.

The Assam power ministry is expected to back the IIT pilot project.

Das says a storage module like an inverter will have to be fitted to each such rumble strip to store this electricity. The cost of electricity generation and storage per mega watt from speed-breakers will be nearly Rs 1 Crore as opposed to about Rs 8 Crore in thermal or hydro power stations

Material Required:

  • Angle frame
  • Connecting Wires
  • LED
  • 12 VOLTS battery
  • mild steel
  • welding arc
  • dynamo
  • pulley

Working:

When we apply brake, it produces some mechanical friction. We are using a dynamo over here to convert the mechanical energy into the electrical energy. So when ever we will apply some friction will be produced and the dynamo simultaneously will convert the energy into electrical. Further it will give electrical power to the led’s and the led’s will glow up.

APPLICATIONS:

We can use the speed braking system to produce electricity energy in trucks as well as bus system. We can also use this constructive electrical energy to recharge the battery as well. It can also be used to provide the power supply to the indicators so that if anyone is coming behind the vehicle will get an indication of the brake. It will help in reducing the accidental cases as well.

More output in less time

CONCLUSION:

After all the testing we are successful in representing our idea of the project in practical way. The project on which we are working is working with very ease and efficient way.The speed barker is working in a right manner and it is producing energy when we put the brake some friction is produced by applying brake on it. A dynamo is being used to convert mechanical energy into electrical energy. Dynamo delivers electrical energy hence it gives electrical output to the led. After getting the power supply from it the led’s glows up.

Merits of power GENERATION THROUGH speed breaker

At a very first glance, this project holds very less space to spread out it over the any road without encountering any problem of maintenance alike hydro power plant, steam power plant, etc. It’s taking very less floor area without getting the traffic obstructed on the road. On the other hand, it is even very suitable and convenient as simple energy conversion from very, not so complex, simple mechanism of cog wheels which are connected to motor assembly e.g. Crank-Shaft, Roller, and Rack- Pinion. But we are using Roller Mechanism.

pneumatic hammer

A pneumatic hammer is more commonly referred to as a jackhammer or power hammer. They are of the same family and do roughly the same thing on differing scales. If you are driving through a big city then you have most likely seen them used by city workers as they break up a road for some reason unknown to you. A pneumatic hammer is typically connected to an air compressor that feeds into the device. Once you apply pressure to the triggers the blade begins to move at a very rapid RPM up and down through the shaft. This generates enough thrust to break apart most materials. The pneumatic hammer can be found in many sizes and speeds and some can have their maximum speed adjusted to your needs. The article that follows will go over several things that a pneumatic hammer is used for.

Road Construction

A pneumatic hammer is one of the main tools of workmen that are contracted the job of road repair. They often use the pneumatic hammer to chisel away the road to create an even surface in which to lay asphalt. They are also used to break through the road to the sewers below in order to create new manholes or access points. What many people do not realize is that roads are made from layers upon layers of asphalt, stone, concrete and other materials. This makes a road very difficult to break through without using a pneumatic hammer.

Rock Removal

When you are digging trenches for use as ponds, swimming pools or house foundations you may come into contact with a large boulder. Most rocks you come across are easily removed but some cannot even be removed by using a backhoe. These large boulders hinder projects often. A pneumatic hammer may be called in and used to chip away at the boulder. The pneumatic hammer will break off large chunks of the boulder that will manageable.

Concrete Walls

Concrete wall removal is difficult and made more so when enforced with steel. If you could knock it over it still will be impossible to move. The solution to this problem is to use the pneumatic hammer to break it into chunks that can be removed with a bulldozer or other such heavy machinery. A pneumatic hammer was used to break away the Berlin Wall. Using a pneumatic hammer for this particular problem requires one that is portable. You will also need to be able to be elevated in order to reach what has to be removed. Smaller pneumatic hammers are used to install concrete hardware without having the user exert any strength.

Building Construction and Demolition

Tools that are traditionally used to rip down a home or aspects of it include sledgehammers, axes, pry bar and other pieces of equipment. Large pneumatic hammers can be used to break apart the foundation of the building. This is also the case for walls. A small pneumatic hammer can be used to install large nails, bolt and the like through metal beams, duct and conduit.

Pneumatic Hammer Working

A pneumatic hammer, also known as air hammer or power hammer uses compressed air to carve or chip away at stone, metal and other materials. It is a tool generally used to shape or smooth a surface area, to dig holes or cut through a surface. An air hammer, which is a replacement for the traditional hammer and chisel, is a handy tool that is very valuable for its speed which at times may lack a bit of precision in the final result. Pneumatic hammers are generally attached by a tube or hose to a large tank that pumps up air and thus making the pistons move.

 

Material Required:

  • Pneumatic cylinder
  • solenoid valve
  • air compressor
  • hammer
  • shafts
  • metallic based
  • clamps

Applications:

Automatic hammer can be used in industries where metal sheets are being prepared. It will save the time and the cost of the man power and consumer less human energy. It is widely used in industries for producing the plain metal sheets mechanism.
ADVANTAGES

CONCLUSION:

After all the testing we are successful in representing our idea of the project in practical way. The project on which we are working is working with very ease and efficient way.The hammer is working in a right manner by hitting the objects accurately with pressure.

Multi-nut opener

Introduction:

A nut is a type of fastener with a threaded hole. Nuts are almost always used opposite a mating bolt to fasten a stack of parts together. The two partners are kept together by a combination of their threads’ friction, a slight stretch of the bolt, and compression of the parts. In applications where vibration or rotation may work a nut loose, various locking mechanisms may be employed: Adhesives, safety pins clockwise, nylon inserts, or slightly oval-shaped threads. The most common shape is hexagonal, for similar reasons as the bolt head – 6 sides give a good granularity of angles for a tool to approach from (good in tight spots), but more (and smaller) corners would be vulnerable to being rounded off. Other specialized shapes exist for certain needs, such as wing nuts for finger adjustment and captive nuts for inaccessible areas.
Nuts are graded with strength ratings compatible with their respective bolts; for example, an ISO property class 10 nut will be able to support the bolt proof strength load of an ISO property class 10.9 bolt without stripping. Likewise, an SAE class 5 nut can support the proof load of an SAE class 5 bolt, and so on.
A wide variety of nuts exists, from household hardware versions to specialized industry-specific designs that are engineered to meet various technical standards.

Material Required:

  • Dc motors
  • Angle frame
  • metallic structure
  • nut openers
  • Two way switches
  • wires
  • 12 volts dc battery

Working:

When give power supply to the dc motors by using 12 volts dc battery the dc motors start rotating in anti-clock directions so that we could be able to open the nuts with ease. The dc motors are attached with the angle frame. We have attached a nut opener structure with the Dc motors. Which is exactly of the same size of the nuts so that can open them in a right manner. So when the dc motors removes in anti-clock direction simultaneously nut opener also start moving in the same direction and start loosening the nuts and at the end the open the nuts in a fine way.

Applications:

Multi nut opener can be used to open ups the tyres of the cars, trucks and in many places. It will save the time and the cost of the man power and consumer less human energy. It is widely used in industries for nut opening mechanism.

CONCLUSION:

After all the testing we are successful in representing our idea of the project in practical way. The project on which we are working is working with very ease and efficient way. We are able to open the multi nuts on the same time.

Continuous Variable Transmission 

INTRODUCTION:

In continuously variable transmission (CVT) infinite number of effective gear ratios changes from maximum to minimum values. The difference between other mechanical transmissions and continuously variable transmission (CVT) is few different distinct gear ratios to be selected. Better fuel economy can be achieved by enabling the engine to run at most effective revolutions per minute in continuously variable transmission (CVT) than other mechanical transmission systems.

A continuously Variable transmission (CVT) is a transmission which can gradually shift to any effective gear ratios between a set upper and lower limit. The almost infinite variability of a CVT allows the engine to maintain a constant speed while the vehicle increases in velocity. This can result in better vehicle performance if the CVT is shifted such that the engine is held at the RPM that it runs most efficiently at and/or produces the most power. Because there are no steps between effective gear ratios, CV T’s operate smoothly with no sudden jerks commonly experienced in manual transmission. Since drivers expect a car to jerk or the engine sound to change as they press the accelerator pedal further, it is very confusing for them when the car smoothly accelerates without the engine revving faster. Drivers have unfortunately perceived this as the car lacking power which is causing a marketing problem for the transmissions
Mainly the CVT has primary and secondary clutches which are connected by belt in which the Primary clutch is connected to the Ac motor and Secondary Clutch connected to the gear box and the power is transmitted from Primary clutch to the Secondary clutch by belt.

Primary and Secondary clutches are made of pulley’s. To have the required performance of the vehicle the speed of the engine has to be reduced in the CVT, this variation in the speed reduction can be achieved by changing the contact diameters of the belt on pulleys. In normal pulleys the diameter cannot be changed so to have change in the contact diameter between belt and pulley, the pulley used are different from the conventional pulleys.

Material Required:

  • V-Belt Pulley’s

  • Ac motor

  • Bearings

  • Nut Bolts

  • Shafts

  • Belt

  • Metallic Stand

Working:

For power transmission instead of gears we are using Two pulley’s connected by a belt. We are using AC motors on one side to drive the primary section of the Project. Primary Section includes Pulley with bearings connected to AC motor. Ac motors turn on the Primary pulley. The other one is connected to the rest of transmission to the wheels. The magic of CVT is that the size of the pulleys can change from small to large, and infinite sizes in between. So to start off with, the AC motor’s pulley will be small and the other one large, In this case the speed at the Secondary side of the project will low. As the Diameter of the Primary is about 20 mm and the diameter of the Secondary is about 42 mm which is very large. So the speed will be low at the secondary side of the CVT. Once the we change the diameter of the primary pulley, As we start increasing the diameter and take make it up to extreme level suppose 42 mm. In this case the diameter the secondary reduces about 20 mm. Now the speed of the Secondary pulley increases. Hence it starts delivering high amount of power transmission and RPM( revolution per minute).

Applications:

Automatic Drain Cleaner

Introduction:

Cleaning of drains/gutters has always been a problem. Labors cleaning gutters & drain seems unethical and also leads to a high risk of them catching infections or poisoning due to large amounts of waste/chemicals in them. Also throwing of bottles/plastics and other such objects into the gutters lead to narrowing and eventually blockage in gutter flow. This leads to overflow in many cases. So here we provide a fully automated drain gutter cleaning mechanism to tackle these modern day gutter jamming issues. Our system uses an automated gutter/drain cleaning system that lets fluids flow through it but catches large solid waste like bottles & plastic and accumulates it. So gutter cleaners need to just clean these gutter cleaning systems installed at points instead of cleaning entire gutter floors. Our system consists of metal teeth based jaws that wait at the bottom of the mechanism. It is mounted in a frame to hold the system upright in the gutter. The vertical frame bed is used to let liquid flow but catch all solid waste. The mechanism consists of a filter basket on top of it. After particular time intervals the jaw lifts up using a motorized shaft which is connected using a chain to the jaws. It then reaches the top and turns upside down to dump the solid waste. Now after dumping the waste, the motor rotates again to bring the jaw again to the bottom position to collect more waste. The system is a very efficient way to cleaning gutters & drains and also requires very low power since it will only rotate once or twice a day to dump the solid waste

Waste water is defined as the flow of used water from homes, businesses, industries, commercial activities and institutions which are subjected to the treatment plants by a carefully designed and engineered network of pipes. There are large no.of machines used for removing out the wastes from drains.

Material Required:

  • Sprocket Gears

  • Welding Set

  • Cutters

  • grinding wheels

  • Angle 1.5 inch 3 mm 20 feet

  • Chain with special hole ¾ inch pitch

  • Sheet metal

  • Wire 3 mm 3 feet

  • Sheet 3 feet x 3 feet

  • DC Motor

  • Battery

Working:

In this project we are using Dc motors to operate the project. Dc motors is being used to rotate sprocket gear which helps in moving the chain mechanism. The metal plates which are being used to clean the wastage materials are attached to the chain by using hooks. So when we give power supply to the DC

Motor through the 12 Volts battery it starts revolving. It helps in moving the sprocket gear as well as the chain mechanism. Hence with the movement of the chain our metal plates starts moving Up and Down. It starts collecting the wastage material on them and through them out to the garbage container which is attached with the metallic stand on the back side. For the blockage of the wastage material we are using a net which will block the wastage material at one pint. After that metal plates will collect the wastage material form the bottom of the structure and will through it out to the garbage cleaner.

ADVANTAGES

  1. Low cost
  2. Reliable
  3. Portable
  4. Flexible
  5. Easy to use- system is very easy to understand

Applications:

  • Used for cleaning the water in canals and rivers.

CONCLUSION:

After all the testing we are successful in representing our idea of the project in practical way. The project on which we are working, is working with very ease and efficient way. We are able to fetch out the wastage material from the water and be able to collect it in the garbage collector container.

Hydraulic Bridge

INTRODUCTION

Hydraulic bridge is our major project . in this project we will move bridge using hydraulic pressure. Hydraulic actuators controlled energy to the punch. so the Operator needs to provide only modest effort regardless of conditions. Hydraulic Punching machine helps to make hole in Various size by changing tool. As well, Hydraulic Punch provides some feedback of forces acting on the Sheet and Hole can Made in Sheet metal.

Hydraulic Hole punching machine is reduce Effort To Operator. Operator Need Very Less amount of effort.

Hydraulic hole punching machine operated by compressed Air. Hydraulic clamp have Hydraulic Cylinder, 5/2 Flow control Hand Lever valve With a punch machine holes are punched in work pieces via a Hydraulic cylinder. The cylinder is equipped with two sensors 1S1 and 1S2 which report a 1 if the back or the front of the end state is reached and is controlled via a magnetic valve. The cylinder seems simple. Moving out of position is effected via compressed air as soon as 1Y1 is activated, moving into position is effected via spring force.

The punch system is activated via two push-buttons, S1 and S2. In order to avoid accidents during the production both buttons have to be activated to run the punch machine.

A control has to be installed which ensures that both buttons are activated before the cylinder punches a hole into the work piece. In addition, safety measures have to be taken so that no manipulation is possible, for example, the push-button is glued. That means that the punch must only be operated when the two buttons are actually pressed anew.

The following tasks result from this exercise:

Creation of an assignment table with inputs and outputs

Creation of the project in Step7

Creation of symbol table in Step7

Creation of the program

Checking with PLCSIM

Solution approaches: In order to put this control into practice an Edge evaluation is necessary in any case. This is the only way that the running of the punch machine is guaranteed when the buttons are pressed (signal 0 -> 1). The output 1Y1 has to be controlled with memory units as otherwise the cylinder has to “save” its state after the two buttons have been pressed, before the front end state resets the saved state.

WORKING PRINCIPLE

Hydraulic Cylinder.

Compressor.

Solenoid control valve

Die(male, female)clamp

The main objective of our project presentation topics is to designing and developing a very compact, punch making machine. Initially the switch unit operates the compressor which delivers the air to the solenoid valve at certain pressure. The solenoid controls the flow direction of air to the Hydraulic cylinder. Thus the reciprocating motion of the Hydraulic cylinder creates high force to punch the work piece. This part consists of two parts one is fixed called upper die, at the base and other is fixed called lower die at the end of piston rod. This part is moved up and down to provide the force on the object.

Here in this project presentation topics we used for carrying the objects from one side to another side the object when it comes, if it detects the object means it will out puts a low pulse to the controller. Hydraulic is act as punching equipment. We can connect seal or cup cast with the Hydraulic for cup production. Different seals and casts are used for punching the different shapes. When control unit detects the low pulse from then that will ON the Hydraulic for Punch. After a second the controller will OFF the Hydraulic. After getting the punch from the Hydraulic spiral punch making.

Pneumatic Sheet cutter

INTRODUCTION:

We are using scissors fro simple sheet metal cutting. It is a manual method so that sheet metals are to be wasted sometime because of mistakes happened such as wring dimensions and also even as simple cutting may take long time. Hydraulic machines are also available for sheet metal cutting. But this method is used only for heavy metal cutting and its cost is very high. We are using a pneumatic system for sheet metal cutting in a easy way. It is operated by a pneumatic hand lever of two way control valve. Control valve is operated by a compressor.

Pneumatic Technology:

Pneumatic is a branch of engineering that makes use of gas or pressurized air. Pneumatic systems used extensively in industry are commonly powered by compressed air or compressed inert gases. A centrally located and electrically powered compressor powers cylinders, air motors, and other pneumatic devices. A pneumatic system controlled through manual or automatic solenoid valves is selected when it provides a lower cost, more flexible, or safer alternative to electric motors and actuators.Pneumatic also has applications in dentistry, construction, mining, and other areas.

MAJOR COMPONETS:

  • Pneumatic Cylinder

  • Solenoid Valve

  • Air compressor

  • Steel Blade

  • Metallic Stand

 

DSC_0654-300x300

Advantages:

  • LOW COST

  • LESS CONSUMPTION OF TIME

  • EASY TO HANDLE

  • SKILLED LABOR IS NOT REQUIRED

  • LESS MAINTENANCE

  • HIGH ACCURACY

  • GOOD SURFACE FINISH

  • LESS FLOOR SPACE

APPLICATIONS:

SHEET METALS are used in various places some of them are given below:

  • CAR BODIES

  • AIRPLANE WINGS

  • MEDICAL TABLES

  • ROOFS FOR BUILDINGS AND MANY OTHER THINGS

  • SHEET METAL OF IRON AND OTHER MATERIAL WITH HIGH PERMEABILITY ALSO KNOWN AS LAMINATED STEEL CORES, AHS APPLICATION IN TRANSFORMERS AND ELECTRIC MACHIES.

Conclusion;

Now we know the pneumatic sheet cutting machine is very cheap as compared to hydraulic machine. The range of the cutting thickness can be increased by arranging a high pressure compressor and installing more hardened blades. This machine is advantageous to small sheet metal cutting industries as they can not afford the expensive hydraulic cutting machine.

Future Scope:

  • It can be made hydraulic power operated by installing the gear oil pump at the place of air compressor and pneumatic cylinder arrangement.

  • It can be made rack and pinion operated or spring and lever operated.

  • The place where there is a scarcity of the electricity the electric motor operate compressor is replaced by an IC ENGINE installed compressor.

Thus in future there are so many modifications, which we can make to survive the huge global world of competition.

Scissor Load Lifter

Introduction:

A scissor Load lifter is used to raise, lower, stack, convey and transfer material between two or more elevations. Lift tables can incorporate rotating platforms, tilt platforms, conveyors as part of their design. The project we are working upon is basically a scissor load lifter which is driven by mechanical terms. Mechanical actuation uses screw, spiral, gear, chain or lever systems to raise or lower the lift.

These lifts are suited for precise control applications where positioning at specific elevation is required or where the lift must maintain a specific elevation for an extended period of time.

Movable Scissor load Lifter:

We are making a movable scissor load lifter so that it can serve more than one workstation. This movable load lifter is manually based lifter. It is basically used to transport a load from one location to another.

A scissor lift is a type of platform which moves in vertical direction. The mechanism incorporated to achieve this function is the use of linked, folding supports in a criss-cross ‘X’ pattern, known as a pantograph. The upward motion is achieved by the application of pressure to the outside of the lowest set of supports, elongating the crossing pattern, and propelling the work platform vertically upwards. The platform may also have an extending ‘bridge’ to allow closer access to the work area (because of the inherent limits of only vertical movement). The operation of the scissor action can be obtained by mechanical means (via a lead screw or rack and pinion system).

Components Required:

  • Metal Strips

  • Bearings

  • rack and pinion gears

  • Nut bolts

  • Screws

  • Channels

  • Metal plates

load lift3

Working:

We are operating the scissor load lifter manually by using rack and pinion gears and handles. The upper plates and lower plates are connected through metal strips arranged in a scissor mechanical design. Rack and pinion gears are attached with the upper plate and also with the nut bolts. When we tighten the screw manually by using rack and pinion gears by applying mechanical pressure on the handle. The scissor load lifter gets collapse and we loose the screw by applying force on the handle Anti clock wise it gets open and finally it lifts the load which is placed on the scissor load lifter up. There are Two conditions for moving up the scissor lift and moving Down the scissor lift.

  • When we move the handle Clock wise

When we move the handle in clock wise direction the Scissor strips gets Collapse as we are using channels for this purpose. It gets goes down in this procedure.

  • When we move the handle in ANTI Clock wise

When we move the handle in Anti-clock wise the scissor strips gets open via channels. This time the scissor load lifter goes up and we can lift the weight which we have placed on it.

ADVANTAGES

  1. Money saving

  2. Time Saving

  3. Efficiency increasing

  4. More output in less time

application

Base on the application of the device, I would say that it is very useful for small industrial, and in hospitals as a patient lifting bed.

CONCLUSION:

After all the testing we are successful in representing our idea of the project in practical way. In future we can modify this scissor load lifter by using Hydraulic and Pneumatic cylinders. We can operate the whole function automatically with these cylinders. The project on which we are working is working with very ease and efficient way.

Rotating Inventory store

Objective and Methodology used:

Inventory store system which Occupies Less Space and with Security.

Introduction and Working. Methodology behind the project is sprocket gear used to move inventory material boxes platform up and Down

Introduction and Working Of Project

In this project we will make rotating Inventory material storage system. In this project there will be multiple place of for inventory material to be placed on chain system . Our purpose is to place multiple inventory material which are being used in by the customer very often in small space and make inventory storage system reliable and secure.

We will use few sensors for Inventory storage materials slots identifications. There will be keyboard to enter the number of platform come down on Ground floor. We will gave 1, 2 3 numeric names to different floors. When any body enters particular no. key , only then related to that number , particular platform will come down.

Components used:

  • Sprocket Gears

  • Welding Set

  • Cutters

  • grinding wheels

  • Angle 1.5 inch 3 mm 20 feet

  • Chain with special hole ¾ inch pitch

  • Sheet metal

  • Wire 3 mm 3 feet

  • Sheet 3 feet x 3 feet

  • Working:

    The inventory material slots are connected with keyboard buttons with some additional circuitry. We are using sensors over here which will detect the particular material store slot and after that with the help of dc motor the required inventory material slot will come down. Dc motor is attached with sprocket gears and chain mechanism. So whenever we will supply voltage to the dc motor it will starts rotating, so the inventory material slots. The particular button which is being pressed for the required inventory slot will come down.We can fetch out the required material from it.

    Component Description

    DC MOTOR.

    Here in this project we use slow speed dc motor with gear box to reduce the speed of the platform. This type of gear motor is getting from the second hand machine. Supply voltage of this dc motor is 6 to 9 volt dc. As we vary the voltage speed is also vary. Current consumption of dc motor is 200 ma. It is also possible to use a stepper motor. If we use stepper motor then we require a high current supply. Normal stepper motor require a minimum 1 A power supply.

    A sprocket or sprocket-wheel

    It is a profiled wheel with teeth, cogs,or even sprockets[4] that mesh with a chain, track or other perforated or indented material. The name ‘sprocket’ applies generally to any wheel upon which radial projections engage a chain passing over it. It is distinguished from a gear in that sprockets are never meshed together directly, and differs from a pulley in that sprockets have teeth and pulleys are smooth.

    Sprockets are used in bicycles, motorcycles, cars, tracked vehicles, and other machinery either to transmit rotary motion between two shafts where gears are unsuitable or to impart linear motion to a track, tape etc. Perhaps the most common form of sprocket may be found in the bicycle, in which the pedal shaft carries a large sprocket-wheel, which drives a chain, which, in turn, drives a small sprocket on the axle of the rear wheel . Early automobiles were also largely driven by sprocket and chain mechanism, a practice largely copied from bicycles.

    Sprockets are of various designs, a maximum of efficiency being claimed for each by its originator. Sprockets typically do not have a flange. Some sprockets used with timing belts have flanges to keep the timing belt centered. Sprockets and chains are also used for power transmission from one shaft to another where slippage is not admissible, sprocket chains being used instead of belts or ropes and sprocket-wheels instead of pulleys. They can be run at high speed and some forms of chain are so constructed as to be noiseless even at high speed.

    Inventory material storage slots:

    It is made up of metal. We are making square slots for keeping the inventory material in these slots. Which will rotate up and down. When ever we require the particular material we will press the button for the same slots and it will come down. Now we can fetch the required material from that particular store. In next turn we will press the button for another material and the concerned material slot will come down. And we can take the required material from it as well.

    Applications:

    1. For automation in industry carrying raw material like machines, machines parts, inventory material.

    2. In building material industry for carrying cement etc.

    3. For lift purpose

    4. For automatic car parking as well

    ADVANTAGES

    • Low cost

    • Reliable

    • Portable

    • Flexible

    • Easy to use- system is very easy to understand

    • Secured system like wallet Parking

SMART DUSTBIN

Introduction:

In the recent decades, Urbanization has increased tremendously. At the same phase there is an increase in waste production. Waste management has been a crucial issue to be considered. This paper is a way to achieve this good cause. In this paper, smart bin is built on a microcontroller with metal detector, dc motor and Ultrasonic sensor. Ultrasonic sensor is placed at the top of the dustbin which will measure the stature of the dustbin. The threshold stature is set as 10cm. Project will be programmed in such a way that when the dustbin is being filled, the remaining height from the threshold height will be displayed. Once the garbage reaches the threshold level ultrasonic sensor will trigger the GSM modem which will continuously alert the required authority until the garbage in the dustbin is squashed. Once the dustbin is squashed, people can reuse the dustbin. At regular intervals dustbin will be squashed. Once these smart bins are implemented on a large scale, by replacing our traditional bins present today, waste can be managed efficiently as it avoids unnecessary lumping of wastes on roadside.Foul smell from these rotten wastes that remain untreated for a long time, due to negligence of authorities and carelessness of public may lead to long term problems. Breeding of insects and mosquitoes can create nuisance around promoting unclean environment. This may even cause dreadful diseases.

Though the world is in a stage of up gradation, there is yet another problem [1] that has to be dealt with. Garbage! Pictures of garbage bins being overfull and the garbage being spilled out from the bins can be seen all around. This leads to various diseases as large number of insects and mosquitoes breed on it. A big challenge in the urban cities is solid waste management. Hence, smart dustbin is a system which can eradicate this problem or at least reduce it to the minimum level. Our present Prime Minister of India, Sri Narendra Modiji has introduced the concept of implementing 100 smart cities in India. “Swachh Bharat Abhiyan” was initiated to ensure a clean environment.

The other one is used for Indicating that the Dustbin is full waste material should be extracted Out RIGHT NOW. Ir Sensor sense the waste material and gives an output signal to the system drivers. After getting the signals from IR sensors, The attached circuitry perform their tasks of automatic compressing the waste material in dustbin and when the dustbin is full it automatically extracts the waste material out from it,

 Pneumatic based can crusher

INTRODUCTION

In a continuously develop world, many things kept coming out as if there is nothing impossible anymore for something to exist. This may be part of how and why people manage to adapt to their new lifestyle. Taking a lifestyle as reason how people manage their waste disposal where right now we are directing my focus on how to reduce volume of
waste disposal occupied by cans usually aluminum cans, one of the suitable solutions to minimize the size of the can is by using the pneumatic can crusher.
Apparatus for crushing cans or the like comprises a conveyor formed from a plurality of endless chains cooperating with a fixed inclined crushing plate converging toward the discharge end of the conveyor. The crushing plate includes an actuator strip-like member hinged to the plate which when depressed engages an electrical switch to operate a drive mechanism for the conveyor. A can deposited into the apparatus depresses the actuator which operates the electrical switch to start the drive mechanism. The can is gripped by the chain conveyor and pulled downward between the conveyor and crushing plate flattening the can. When the flattened can exits the crushing apparatus the actuator is released stopping the drive mechanism. A support housing for the apparatus is provided with an opening for receiving cans which is spaced a distance from the crushing plate and conveyor to reduce the risk of injury.
Why is it important to crush a can?

When we drink beverage that we desire the most and finish drinking it till the last drop, surely that beverage can will be disposed into a garbage container. Now imagine that the can thrown into garbage and filled the garbage until it is full. The question is how do we reduce the space occupied by only cans? Of course by crushing them but do you consider crushing each can continuously by stomping it. These actions may somehow cause injuries to ankle more or less affecting your lifestyle. Therefore a device called pneumatic can crusher would help to settle those
entire uncrushed can effortless. Other than avoiding injuries, this device would contribute on good recycling habit where a person will be having fun crushing cans before they throw it away in garbage container.

WORKING

Pneumatic can crushers are powered by air pressure. This device is fitted with a pneumatic cylinder (pressurized tank) that pumps air with a tremendous force to set the crushing device into motion, which then falls onto the can. You have to just place the device in a chamber that is fitted with the crushing device. The chamber is completely enclosed for safe operation. Once the tool starts, you will get the desired result in seconds. Some models of pneumatic can crushers are designed to crush empty tins of around 10 liter in capacity. It can effortlessly reduce the volume of the tin to approximately 1/6th of its original size. The force of compressed air pushes a ram onto the tin and crushes it within 30 seconds.

A pneumatic can crusher is constructed from sturdy material and can easily crush 12 or 16 oz cans. These can crushers are robustly engineered to deliver a power-packed performance for years to come. You can find these devices at your nearest hardware store. You can always search the Web as there are a number of online shops that keep a variety of pneumatic can crushers to meet individual needs.

Solar Grass Cutting Machine

Introduction and Working:

Grass Cutting project is our major project. We will operate this machine using solar panel. We found tough to get idea from Internet because its tough to get combined material to make mechanical design.

There are two ways to cut grass – one radial and another is axial. Normally grass cutter machines are axial type. We will cut grass with radial method.

We will use HSS – High speed steel or CS- carbon steel for cutting grass.

We will use high torque PM -permanent magnet type motor for driving blades. Blade will be welded or we will use nut bolt assembly.

Which will help to charge battery. First of all solar panel will give AC output. So ac will be converted in to DC using bridge and filters. Out put of supply will ve given to battery charging circuit.

An uninterruptible power supply, also uninterruptible power source, UPS or battery/flywheel backup, is an electrical apparatus that provides emergency power to a load when the input power source, typically the utility mains, fails. A UPS differs from an auxiliary or emergency power system or standby generator in that it will provide instantaneous or near-instantaneous protection from input power interruptions by means of one or more attached batteries and associated electronic circuitry for low power users, and or by means of diesel generators and flywheels for high power users. The on-battery runtime of most uninterruptible power sources is relatively short—5–15 minutes being typical for smaller units—but sufficient to allow time to bring an auxiliary power source on line, or to properly shut down the protected equipment.

While not limited to protecting any particular type of equipment, a UPS is typically used to protect computers, data centers, telecommunication equipment or other electrical equipment where an unexpected power disruption could cause injuries, fatalities, serious business disruption and/or data loss. UPS units range in size from units designed to protect a single computer without a video monitor (around 200 VA rating) to large units powering entire data centers, buildings, or even cities

The primary role of any UPS is to provide short-term power when the input power source fails. However, most UPS units are also capable in varying degrees of correcting common utility power problems:

Power failure: defined as a total loss of input voltage.

Surge: defined as a momentary or sustained increase in the mains voltage.

Sag: defined as a momentary or sustained reduction in input voltage.

Spikes, defined as a brief high voltage excursion.

Noise, defined as a high frequency transient or oscillation, usually injected into the line by nearby equipment.

Frequency instability: defined as temporary changes in the mains frequency.

Harmonic distortion: defined as a departure from the ideal sinusoidal waveform expected on the line.

UPS units are divided into categories based on which of the above problems they address[dubious – discuss], and some manufacturers categorize their products in accordance with the number of power related problems they address.

In this project we will use Pic controller to controller to control the whole function.

We will use indicator for Low voltage , Current usage.
