Q: What Is Chain Drive?

Chain drive is a way to transfer mechanical power from one place to another. Chain drives are widely used in vehicles such as bicycles and motorcycles to transfer power to the wheels. It is also used in different types of machines. Most often, power is communicated by a roller chain, known as a drive chain or transmission chain, that passes over a sprocket gear, with the gear teeth intersecting holes in the chain's links. The gear is rotated, and this pulls the chain, exerting mechanical force in the mechanism. The chain is made up of several rigid links that are held together by pin joints to provide the necessary flexibility to wrap the driving and driven wheels. Chains are mostly used to transfer speed and power from one shaft to another when the center distance between their shafts is small such as in bicycles, motorcycles, agricultural machinery, conveyors, rolling mills, road rollers, etc. The chain can also be used for long center distances of up to 8 metros. Chains are used for velocities up to 25 m/s and power up to 110 kW. In some cases, higher power transmission is also possible. These wheels have special profile teeth and fit the corresponding recess in the chain link. Toothed wheels are known as sprocket wheels or simply sprockets.

Q: Chain Drives for Transmission:

The Chain Drives are the most important drives for transmissions of electricity. It is a positive drive system as opposed to self-drive. The velocity ratio of the chain drive, that is, the ratio of the angular velocity of the driving sprocket wheel, remains constant without slip and without creep. In this case, the velocity ratio is as high as eight, which is quite high. Completes assembly of the chains drive system. It consists of two toothed sprockets and a chain. Chain drives are very suitable for power transmission for short center-to-center distances and can be suitably used up to 2.5 meters but, however; The distance can be increased in most special applications. The single-chain can be used to drives multiple shafts to transfer power.

Chain drive, also known as a chain drive mechanism, is a way to transfer mechanical chain power from one place to another. Chain transmission is widely used in vehicles such as bicycles and motorcycles to transfer power to the wheels.

It is also used in different types of machines. Most often, power is communicated by a roller chain, known as a drive chain or transmission chain, that passes over a sprocket gear, with the gear teeth intersecting holes in the chain’s links.

The gear is rotated, and this pulls the chain, exerting mechanical force in the mechanism.

The chain is made up of several rigid links that are held together by pin joints to provide the necessary flexibility to wrap the driving and driven wheels.

Chains are mostly used to transfer speed and power from one shaft to another when the center distance between their shafts is small such as in bicycles, motorcycles, agricultural machinery, conveyors, rolling mills, road rollers, etc.

The chain can also be used for long center distances of up to 8 metros. Chains are used for velocities up to 25 m/s and power up to 110 kW.

In some cases, higher power transmission is also possible. These wheels have special profile teeth and fit the corresponding recess in the chain link.

Toothed wheels are known as sprocket wheels or simply sprockets.

Thus the sprocket and chain are constrained to move together without slipping and ensuring the correct velocity ratio.

Chains are suitable for relatively long or short center distance drives and give a more compact drive than is possible with belts.

Some Features of Chain Drive:- The alignment of the shaft should be more precise than that of the belt. Center distance is not as important as gear drives.

Proper lubrication must be provided for satisfactory service life. Their efficiency is compared to any other type of positive motivation.

Chain drives have greater versatility, adaptability, and reliability. They are an important component of lifting and moving machinery.

Their cost is competitive due to automated production and extremely high rates of demand. Chains are low in cost, easy to install and maintain.

Basic characteristics of chain drives include a stable ratio, as no slippage or creep is involved, long life, and the ability to drive multiple shafts from a single power source.

Chain Drives for Transmission:

The Chain Drives, often referred to as chain drive transmission, are the most important drives for power transmission chain drive of electricity. It is a positive drive system as opposed to self-drive.

The velocity ratio of the chain drive, that is, the ratio of the angular velocity of the driving sprocket wheel, remains constant without slip and without creep.

In this case, the velocity ratio is as high as eight, which is quite high. Completes assembly of the chains drive system. It consists of two toothed sprockets and a chain.

Chain drives are very suitable for power transmission for short center-to-center distances and can be suitably used up to 2.5 meters but, however; The distance can be increased in most special applications.

The single-chain can be used to drives multiple shafts to transfer power.

These chains have longer life as compared to belt drives, but the operation is not so smooth.

The chain drive produces noise in operation due to impact when the chain roller contacts the sprocket tooth.

There is variation in the speed of the chain from one tooth to the next.

This can cause vibration. The lubrication of the chain is done essentially to ensure smooth working, with a noiseless operation, and to ensure a long and trouble-free life of the chain.

In this regard, the arrangement of the transmission chain drive system will essentially consist of an endless chain and two wheels called sprockets. Sprockets are toothed wheels, as shown, attached to an endless chain.

Endless chains of different sizes are formed depending on the distance from the center to the center of the circle.

The most important applications of chain drive systems in power transmission are bicycles, motorcycles, scooters, machine tools, conveyors, etc.

Types of Chain Drives:

1. Roller Chain

This types of chain, which can be defined as define chain drive, are most commonly used for the chain drive is used for transmission of mechanical power on many types of household, industrial and agricultural machinery, including 5 machines that use chain drives, including conveyors, wire- and tube drawing machines, printing presses, cars, motorcycles, and bicycles.

A roller chain consists of series of small cylindrical rollers held together by side links. It is driven by toothed wheels called sprockets.

It is simple, reliable, and efficient for power transmission. These chains are usually smaller in diameter than the height of the chain’s link plates.

Link plate serves as guides when the chain engages the sprocket, Chain tracks or also serve as a guide to support the material on the way, as characteristic of conveyors and some bucket elevators. Roller chains are used for both drive & conveyor applications.

The chain most commonly used for drives is the single-strand standard chain roller chain.

The power rating capabilities of these series cover a wide range of drive load requirements.

Multiple-strand roller chains are used to provides increased power capacities without the need to increase the chain pitch or its linear speed.

2. Silent Chain

Silent chains, also called inverted tooth chains, consist of a series of tooth link plates mounted on joint components in a way that allows free flexing between each pitch.

Silent chains are made up of vertical rows of flat link plates, which have a gear-type shape designed to engage the sprocket teeth in the same way that a rack engages a gear in the picture. It is being displayed.

The links are held together by one or more pins at each chain joint, which also allows the chain to flex.

A silent chain from differents manufacturers usually cannot be connected together. Standard silent chain is used in a wides variety of industrials drives where a compact, high speed, smooth, low noise drive is required.

High-performance silent chains are available in a wide range of sizes with pitches and widths and are used on very high-speed drives where exceptional smoothness and quietness are required.

These series are commonly used in industrial equipment where ultimate smoothness is required.

3. Leaf Chain

Leaf chains are designed for lifting rather than power transmission. The Tension is high, but the pace is slow.

Normally the chains work intermittently. The main considerations in the design of leaf chains are tensile load, joint wear, and link plate and sheave wear.

Leaf chains are not forged with sprockets, as they are intended to run on mirrors, so there is no provision for them to the sprocket.

Leaf’s chains must often lift very large loads, & therefore require high yield strength, and do not stretch permanently when they lift large loads. Perhaps the most common use for a leaf chain is on lift trucks.

4. Flat Top Chain

Flat-top chains are widely used on conveyors, which are basically used on special types of slate conveyors.

Includes flat-top series of steel top plates with hinged-like barrels mounted on each side. Pins are inserted through the barrel to form a joint. These act as both beams and bearing.

The pins are maintained by a press fit or heading into the barrel of one top plate and are free to clear into the barrel of the next link.

The connecting pin is usually either mounted or enlarged at one end to maintain the pin in a barrel of the top plate.

Thus a continuous length of flat-top chains is formed. The flat-top chain is for conveying only.

5. Engineering Steel Chain

The Engineering steel chains were first developed in the 1880s, designed for tough conveying applications. Most engineering steels chain are used in conveyors, bucket elevators, & tension linkages.

Only a few are used in the drive. The main design considerations for these series are tensile load, multiple types of wear, lubrication, and environment.

Wear is the most important parameter when designing engineering steel chains. Joint wear, roller & bushing wear, & sidebar, and track wear are all major concerns for conveyor chains.
