Chains are divided into four types: transmission chain, conveyor chain, traction chain and special special chain according to different uses and functions.

Transmission chain: a chain mainly used to transmit power;

Conveyor chain: mainly used for conveying boring chains;

Traction chain: mainly used for pulling and lifting the chain;

Special chain: mainly used on special mechanical devices. Chains with special functions and structures.

In the same kind of products, according to the basic structure of the chain, according to the shape of the components, the parts and parts that mesh with the chain, and the size ratio between the parts, the chain product series to which they belong is divided. There are many types of chains, but their basic structures are only the following, and the others are deformations of these. We can see from the above chain structures that most chains are composed of chain plates, chain pins, bushings and other components. Other types; the chain only changes the chain plate according to different needs, some are equipped with scrapers on the chain plate, some are equipped with guide bearings on the chain plate, and some are equipped with rollers on the chain plate, etc. , These are modified for application in different occasions.
