Definition - What does Chain Drive mean?
A Chain Drive is a mechanical device which is used to rotate the camshaft in internal combustion engines and various gears which are connected through the chain drive. It is also used to transmit mechanical power from one place to another and consists of chain links that are connected in an endless series which mesh with the gear tooth sprockets. Chain drive along with the gear sprockets acts like a flexible gearing system for transferring power from one movable part to other movable parts of the machine.
Petropedia explains Chain Drive
The use of chain drives is simple and yet effective way of transmitting mechanical power to rotate the parts of a machine. The chain has links that are meshed easily with a tooth sprocket that is similar to a pinion gear and this action provides a positive speed ratio between the driving unit and a driven unit in a machine. These are the three primary functions of a chain drive:
- Used to transmit power from one mechanical part to the other
- Used to convey material
- Used as a faster way of transmission
Some of the advantages of chain drives are as follows:
- They do not slip or creep like belt drives.
- They are more efficient than belt drives as there is no slippage because of which power loss takes place.
- They can operate easily at high temperatures and in wet conditions as well.
- They are easy to install.
- They can withstand chemical and abrasive conditions.
- They are simple and cost-effective.
- They are a practical option for slow speed drives.
