SYNOPSIS

Mechanical power may be transmitted directly using a solid structure such as a

driveshaft; transmission gears can adjust the amount of torque or force vs. speed in

much the same way an electrical transformer adjusts voltage vs current.

Hydraulic systems use liquid under pressure to transmit power; canals and

hydroelectric power generation facilities harness natural water power to lift ships

or generate electricity. Pneumatic systems use gasses under pressure to transmit

power; compressed air is commonly used to operate pneumatic tools in factories

and repair garages. A pneumatic wrench (for instance) is used to remove and

install automotive tires far more quickly than could be done with standard manual

hand tools.

In this project , the rotary power is transmitted at perpendicular direction through four rods without using gear drive transmission.

It is made up of mild steel material. The whole construction of machine is

placed on the base plate. The grinding tool is screwed to the main spindle which is

driven through the gearless drive transmission from the motor. This motor with

the gearless drive mechanism are mounted in base plate.The stone is fixed in the

spindle and rotated by motor.

INTRODUCTION

This is a self – assessment test on the part of the students to assess his

competency in creativity.

During the course of study, the student is put on a sound theoretical

foundation of various mechanical engineering subjects and of course, to a

satisfactory extent. Opportunities are made available to him to work on different

kinds of machines, so that he is exposed to various kinds of manufacturing

process.

As a students learn more and more his hold on production technology

becomes stronger. He attains a stage of perfection, when he himself is able to

design and fabricate a device.

This is the project work. That is the testimony for the strenuous training,

which the student had in the institute. This assures that he is no more a student,

he is an engineer.

This report discuses the necessity of the project and various aspects of

planning , design, selection of materials, fabrication, erection, estimation and

testing.

PRECAUTION BEFORE SELECTION OF THE PROJECT

12

PRECAUTION BEFORE SELECTION OF THE PROJECT

Before rushing out of buy the material for the component first determine

the Size of material required for gearless drive in order to transmit the load.

Obviously the first thing to look at is Whether the drive having an easier

provisions to attach the with the input and output devices or what extent we

modify this. If the drive having easier provision fit the devices to transmit the

load or and them try.

PROJECT PLANNING

14

PROJECT PLANNING

CONCEPT OF THE PROJECT

Before starting every project its planning is to be done. In planning

functions are life the functions of never in our body. planning a project is a very

important task and should be taken up with great care as the efficiency of the

whole project largely defends upon its planning, while planning a project each

and every details should be worked our in anticipation should be carefully

considered with all the relative provisions aspects.

PROJECT CAPACITY

The capacity of the project must be decided considering theamount of money which can be invested. The availability of materialand machines and usefulness of the project.

DESIGN AND DRAWING

Having decided about the project to be manufactured at must be designed.

Design work should be done very considering all the relevant factors.

After design the project detailed drawing are prepared. DetailedSpecification for

raw material and finished products should be decided Carefully along with the

specification of the machine required for the manufacture.

15

MATERIAL REQUIREMENTS

The list of material required for manufacture is prepared from the drawing.

The list is known as “Bill of materials”. Availability of these materials is surveyed

and purchased from the market.

OPERATION PLANNING

Next work of planning is to “select the best method” manufacture the product,

so that the wastage of materials, labour, machines and time can be eliminated by

considering various methods. The best method is to be selected for fabrication

and other works.

The proper method and proper person and the purposes of operation, necessity

operation, proper machine planning. The best method is the developed and is

applied to fabricate the project.

MACHINE LOADING

While planning proper care should be taken to find the machining time for the

operation as correct as possible. So that arrangement of full use of machines can

be made and the machine loading program can be decided.

16

PURCHASE CONSIDERATION

It is difficult to manufacture all the components needed for the project

in the machine shop. In each case, we should decide whether tomake or buy

about a particular item. It is decided during the planning after making a complete

study of relative merits and demerits.

EQUIPMENT PROCEDURE

Results obtained from “operation planning” and machine loading help in

calculating the equipment require Specification of the equipment should be laid

down by considering then drawings. Drawings will also help in deciding the

necessary requirement of tools and accessories.

FABRICATION DETAILS

18

FABRICATION OF PARTS DETAILS

1. BED

It is made up of mild steel L andle channel material. The motor is

engaged with base plate. All the parts for drive this mechanism are mounted

on base plate or bed.

2. GRINDING STONE

The stone is fixed in the spindle and rotated by motor.

3. FOUR “ L “ RODS DRIVE TRANSMISSION

The power is transmitted from the motor , V belt drive to the grinding wheel

through the these four L shaped rods having 8mm diameter. These rods are

transmit the power in perpendicular directions and sliding in two cylinders.

4. V BELT DRIVE TRANSMISSION;

A belt is a loop of flexible material used to link two or more rotating shafts

mechanically. Belts may be used as a source of motion, to transmit power

efficiently, or to track relative movement. Belts are looped over pulleys. In a two

pulley system, the belt can either drive the pulleys in the same direction, or the belt

may be crossed, so that the direction of the shafts is opposite. As a source of

motion, a conveyor belt is one application where the belt is adapted to

continuously carry a load between two points. The power is transmitted from the

19

motor to the grinding wheel through four L shaped rods and V belt drive.The

belt is a V belt of B 45.The driving pulley is made in cast iron material of 25 mm

diameter and the driven is made in cast iron material having 100 mm diameter. The

purpose of this V belt drive is to reduce the speed from the motor.

Vee belts

Vee belts (also known as V-belt or wedge rope) solved the slippage and alignment

problem. It is now the basic belt for power transmission. They provide the best

combination of traction, speed of movement, load of the bearings, and long service

life. They are generally endless, and their general cross-section shape is trapezoidal

(hence the name "V"). The "V" shape of the belt tracks in a mating groove in the

pulley (or sheave), with the result that the belt cannot slip off. The belt also tends

to wedge into the groove as the load increases—the greater the load, the greater the

wedging action—improving torque transmission and making the V-belt an

effective solution, needing less width and tension than flat belts. V-belts trump flat

belts with their small center distances and high reduction ratios. The preferred

center distance is larger than the largest pulley diameter, but less than three times

the sum of both pulleys. Optimal speed range is 1000–7000 ft/min. V-belts need

larger pulleys for their larger thickness than flat belts.

For high-power requirements, two or more vee belts can be joined side-by-side in

an arrangement called a multi-V, running on matching multi-groove sheaves. This

is known as a multiple-V-belt drive (or sometimes a "classical V-belt drive").

V-belts may be homogeneously rubber or polymer throughout, or there may be

fibers embedded in the rubber or polymer for strength and reinforcement. The

20

fibers may be of textile materials such as cotton or polyester or, for greatest

strength, of steel or aramid (such as Twaron or Kevlar).

When an endless belt does not fit the need, jointed and link V-belts may be

employed. However they are weaker and only usable at speeds up to 4000 ft/min.

A link v-belt is a number of rubberized fabric links held together by metal

fasteners. They are length adjustable by disassembling and removing links when

needed.

V pulley

5. AC INDUCTION MOTOR

This AC motor is working in 230 VAC supply.

21

An AC motor is an electric motor driven by an alternating current (AC).

It commonly consists of two basic parts, an outside stationary stator having coils

supplied with alternating current to produce a rotating magnetic field, and an inside

rotor attached to the output shaft that is given a torque by the rotating field.

There are two main types of AC motors, depending on the type of rotor used. The

first type is the induction motor, which runs slightly slower than the supply

frequency. The magnetic field on the rotor of this motor is created by an induced

current. The second type is the synchronous motor, which does not rely on

induction and as a result, can rotate exactly at the supply frequency or a sub-

multiple of the supply frequency. The magnetic field on the rotor is either

generated by current delivered through slip rings or by a permanent magnet. Other

types of motors include eddy current motors, and also AC/DC mechanically

commutated machines in which speed is dependent on voltage and winding

connection.

22

Capacitor start motor

Schematic of a capacitor start motor.

A capacitor start motor is a split-phase induction motor with a starting capacitor

inserted in series with the startup winding, creating an LC circuit which produces a

greater phase shift (and so, a much greater starting torque) than a split-phase

motor. The capacitor naturally adds expense to such motors.

PLUMMER BLOCK

23

STRUCTURE

24

HANDLING THE PLUMMER BLOCK AND BEARING

Rolling bearings are precision components. To maintain accuracies, they must be handled very carefully. In particular, they must be kept clean, not be subjected to long impact, and be protected against possible rusting. Plummer blocks also need similar handling practices.

I. INSPECTION BEFORE INSTALLATION

Before installation a bearing and a plummer block, the blowing point must be thoroughly checked and inspected.

INSPECTION BEFORE INSTALLATION

25

Prepare installation tools, measured instruments, oil stone, lubricant and factory cloth. Before the installation work, remove dust and impurities from these tools

Make sure that the shaft is free from bends or other damages and that it has been dimensioned and formed as specified.

Remove dent marks even through very small from the mating faces with an oil stone or fine emery paper. Check that the contact face to the seal has specified surface roughness. Wipe dust away from the shaft with clean factory cloth.

Remove possible dust and metal chips from the inside of plumber block.

26

Check the flatness of the mounting face of the plummer block. When placed on a frame, the plummer block must be stably seated.

II. PREPARATION FOR INSTALLINT THE BEARING

Unpack the bearing just before the installation work.

If the bearing is to be grease-lubricated, the rust-proof coating on it may remain unremoved. If it is to be oil-lubricated, remove the coating with benzene or kerosene.

27

Preparation for Installing the Bearing

For a bearing with an adapter, check its radial clearance before the installation work. To do so, place it on a flat work bench, and fit a thickness gage between the uppermost roller and the raceway surface on the outer ring to measure the clearance . Do not force the thickness gage in or turn the bearing. Otherwise, the resultant clearance measurement will be greater than the actual clearance.

III. INSTALLATION OF THE BEARING AND ASSOCIATED COMPONENTS

Once careful checking is complete, install the bearing and associated components. For the positional relationship.

28

INSTALLATION OF THE BEARING AND ASSOCIATED COMPONENTS

When a bearing is installed onto a shaft or into a housing. Do not directly hit its end face with a hammer. Otherwise, its design performance can be lost. Always evenly exert force around the entire bearing ring face. Also, do not apply force to one bearing ring.

o EXAMPLE; Outer ring

29

To convey the force via the rolling elements to the other bearing ring inner ring to install the latter. Otherwise, a dent mark or other damage can occur on either or both rings.

When installing a cylindrical bore bearing, whose interference is relatively small, its whole inner rings can be uniformly press-fitted at an ordinary temperature as illustrated .Usually, the inner ring is press-fitted by tapping the sleeve with a hammer. However, when many bearings must be installed at a time, a mechanical or hydraulic press will be helpful.

30

When installing a non-separable bearing to the shaft and housing at a time, apply a press-fitting force to both the inner and outer rings by using a pressure distribution pad.

IV.ASSEMBLING THE PLUMMER BLOCKS

When installing two or more plummer blocks on a shaft, use one block to locate the outer ring of a bearing in the axial direction, and arrange the other block (s) so that the outer ring (s) of bearing (s) in the latter block (s) can more freely in the axial direction.

ASSEMBLING THE PLUMMER BLOCKS

31

Once the bearing has been installed to the shaft and the associated components have been inserted over the shaft, assemble the plummer blocks according to the following procedure.

V. MAINTENANCE AND INSPECTION

To be able to use a bearing to its design life and avoid by accident, check the following points at regular servals.

1. Running sound on bearing. 2. Temperature on bearing or plummer block.3. Vibration on shaft.4. Leaking grease or worn oil seal.5. Loose tightening and mounting bolts.6. Trouble- free operation of the lubrication system, and

loosening or leakage with piping. The bearing arrangement must be inspected while it is a

standstill, check it for the following points:

1. Check appearance the of bearing for any irregularity.2. Fouling of grease ,or contaminants in grease.3. Loose adapter sleeve.4. Worn or damage seal.

VI.BEARING DISASSEMBLY

Straighten the bent tab on the washer, and loosen the nut by two or three turns. Place a drift to a face of the nut. Sightly tap the drift to turn the sleeve. Once be sleeve is shifted in the axial can be direction, the bearing easily removed.

32

Note,however,when the nut as been excessively loosened and only a few ridges remain engaged,and if the nut is further tapped,the threading on the sleeve or nut may be stripped.

33

VII.CYLINDRICAL BORE BEARING

Usually, a cylindrical bore bearing is interference-fitted. Thus, the bearing is simply drawn out by placing a jig to yhr face of the inner ring and exerting a forces illustied with a hand press. However,be careful not to apply a force to the outer ring. When using this tool, make sure that the jig is fully engaged with the face of the inner ring.

VIII.CLEANING THE BEARING

Clean the removed bearing with diesel oil or kerosene.

USE TWO VESSELS.

One for rough cleaning and the other for finish cleaning. Prepare a cleaning station that has a metal screen as illustrated. So that the bearing does not directly contact the fouling on the bottom of vessel. In rough cleaning, virtually all oil and foreign matters should be removed from the bearing which should be immediately transferred to the finish vessel. The finish vessel must be provide with a filter unit to maintain the cleaning agent clean.

Once cleaned, the bearing must be immediately rust-proofed.

The bearings (which have been carefully removed) must be checked whether they can be reused. The judging criterion for reuse should be determined considering the following criteria through a trial-and-error basis.

1. Scheduled operating duration to next regular inspection.2. Importance of the machine that uses the bearing in question3. Operating conditions such as loading and bearing speed.4. Severity of damage on the rolling contact surface.

34

5. Tendency of increasing bearing clearance and wear on the cage.

6. Loss in accuracy, etc.,

IX. STORING THE BEARING

When storing a bearing, pay particular attention to rust prevention. Note that the rust-proofing grease in the bearing will run away at a temperature of 50 to 60 C. Therefore, store a bearing in a dry, cool location at a height at least 30cm above the floor. Remember that wooden crate attracts moisture. Thus, immediately unpack the delivered bearings, and store them on shelves.

Introduction to Grinding wheel

Grinding wheels

A grinding wheel is an expendable wheel that is composed of an abrasive

compound used for various grinding (abrasive cutting) and abrasive machining

operations. They are used in grinding machines.

The wheels are generally made from a matrix of coarse particles pressed and

bonded together to form a solid, circular shape, various profiles and cross sections

are available depending on the intended usage for the wheel. They may also be

made from a solid steel or aluminium disc with particles bonded to the surface.

The manufacture of these wheels is a precise and tightly controlled process, due

not only to the inherent safety risks of a spinning disc, but also the composition

and uniformity required to prevent that disc from exploding due to the high stresses

produced on rotation.

Characteristics

36

There are five characteristics of a cutting wheel: material, grain size, wheel grade,

grain spacing, and bond type. They will be indicated by codes on the wheel's label.

Material, the actual abrasive, is selected according to the hardness of the material

being cut.

Aluminium Oxide (A)

Silicon Carbide (S)

Ceramic (C)

Diamond (D, MD, SD)

Cubic Boron Nitride (B)

Grain size, from 8 (coarsest) 1200 (finest), determines the physical size of the

abrasive grains in the wheel. A larger grain will cut freely, allowing fast cutting but

poor surface finish. Ultra-fine grain sizes are for precision finish work.

Wheel grade, from A (soft) to Z (hard), determines how tightly the bond holds the

abrasive. Grade affects almost all considerations of grinding, such as wheel speed,

coolant flow, maximum and minimum feed rates, and grinding depth.

Grain spacing, or structure, from 1 (densest) to 16 (least dense). Density is the

ratio of bond and abrasive to air space. A less-dense wheel will cut freely, and has

a large effect on surface finish. It is also able to take a deeper or wider cut with less

coolant, as the chip clearance on the wheel is greater.

Wheel bond, how the wheel holds the abrasives, affects finish, coolant, and

minimum/maximum wheel speed.

Types

Straight wheel

Straight wheel

To the right is an image of a straight wheel. These are by far the most common

style of wheel and can be found on bench or pedestal grinders. They are used on

the periphery only and therefore produce a slightly concave surface (hollow

ground) on the part. This can be used to advantage on many tools such as chisels.

Straight Wheels are generally used for cylindrical, centreless, and surface grinding

operations. Wheels of this form vary greatly in size, the diameter and width of face

38

naturally depending upon the class of work for which is used and the size and

power of the grinding machine.

Cylinder or wheel ring

Cylinder wheels provide a long, wide surface with no center mounting support

(hollow). They can be very large, up to 12" in width. They are used only in vertical

or horizontal spindle grinders. Cylinder or wheel ring is used for producing flat

surfaces, the grinding being done with the end face of the wheel.

Tapered wheel

A straight wheel that tapers outward towards the center of the wheel. This

arrangement is stronger than straight wheels and can accept higher lateral loads.

Tapered face straight wheel is primarily used for grinding thread, gear teeth etc.

Straight cup

Straight cup wheels are an alternative to cup wheels in tool and cutter grinders,

where having an additional radial grinding surface is beneficial.

Dish cup

A very shallow cup-style grinding wheel. The thinness allows grinding in slots and

crevices. It is used primarily in cutter grinding and jig grinding.

Saucer wheel

A special grinding profile that is used to grind milling cutters and twist drills. It is

most common in non-machining areas, as sawfilers use saucer wheels in the

maintenance of saw blades.

39

Diamond wheel

Diamond wheel

Diamond wheels are grinding wheels with industrial diamonds bonded to the

periphery.

They are used for grinding extremely hard materials such as carbide cutting tips,

gemstones or concrete. The saw pictured to the right is a slitting saw and is

designed for slicing hard materials, typically gemstones.

Diamond mandrels

Diamond mandrels are very similar to their counterpart, a diamond wheel. They

are tiny diamond rasps for use in a jig grinder doing profiling work in hard

material.

Cut off wheels

Cut off wheels, also known as parting wheels, are self-sharpening wheels that are

thin in width and often have radial fibres reinforcing them. They are often used in

the construction industry for cutting reinforcement bars (rebar), protruding bolts or

anything that needs quick removal or trimming. Most handymen would recognise

an angle grinder and the discs they use.

Use

40

To use the grinding wheel it must first be clamped to the grinding machine. The

wheel type (e.g. cup or plain wheel below) fit freely on their supporting arbors, the

necessary clamping force to transfer the rotary motion being applied to the wheels

side by identically sized flanges (metal discs). The paper blotter shown in the

images is intended to distribute this clamping force evenly across the wheels

surface.

Dressing

Grinding wheels are self sharpening to a small degree; for optimal use they may be

dressed and trued by the use of wheel or grinding dressers. Dressing the wheel

refers to removing the current layer of abrasive, so that a fresh and sharp surface is

exposed to the work surface. Trueing the wheel makes the grinding surface parallel

to the grinding table or other reference plane, so that the entire grinding wheel is

even and produces an accurate surface.
