Chain Drive | Definitions , Types, Advantages and Disadvantages

What is chain drive?

Before going to chain drive we first understand “What is mean by Chain?”

A chain can be defined as a series of links connected by pin joints.

The chain drive consists of an endless chain that wraps around two sprockets.

Advantages of Chain Drive:-

·         

•      Available for long and short range.
•          Drive on multiple axes and a single chain
•         Small in size, small in total.
•          There is no risk of fire.
•         The temperature and environmental conditions do not affect the operation.
•         No initial tension is needed.
•         The efficiency is very high (up to 96%).
•          Do not slip
•          Installation is easier
•          It can withstand difficult conditions
•         They can work in wet conditions.

Disadvantages of Chain Drive:-

Some disadvantages of chain transmissions compared to gear and belt transmissions are:-

•  Requires precise alignment compared to belt drive
•  Frequent lubrication is required
•  Less load capacity compared to gears.
•  Its operation is noisy and can cause vibrations.
•  Not suitable for axes that are not parallel.
•  Cannot be used where precise movement is required
• They need housing
• It should fit loosely, like a tension-er.

Applications of Chain Drives:-

• They are used for energy transmission.
• They are used in the transportation industry.
• They are used for carpentry machines.
• They are used for agricultural machinery.
• They are used in drilling rigs of oil wells.
• They are used for building construction.
• They are used for material handling equipment.
• They are used to lift load.
• They are used to transport materials. 

Classification of Chain Drives:-

Chain Drive are classified into three types:- 

1.       Load lifting chains

2.       Power transmission chains

3.       Hauling chains

1.Load lifting chains:-

 It is used to suspend, increase or decrease the load in material handling operations.

2. Power Transmission Chains:-

The power transmission chains are used to transmitting the power from one shaft to another.

3. Hauling chains:-

It is used to keep the material moving by sliding, pulling or transporting it on the conveyor.
