Chinese Factory Supply Bicycle Transmission Conveyor Chain Roller Chain /Hollow Chain

There are usually two types of transmission mechanisms in the transmission chain: one is the transmission mechanism with fixed transmission ratio and transmission direction, such as fixed ratio gear pair, worm and turbine pair, which is called fixed ratio transmission mechanism; The other is the transmission mechanism that can change the transmission ratio and transmission direction according to the processing requirements, such as the change gear transmission mechanism, sliding gear transmission mechanism, etc., which is called the displacement mechanism.

All parts of the chain are made of carbon steel or alloy steel and heat treated to improve strength, wear resistance and impact resistance. Roller chains can be made into single-row chains and multi-row chains. When transmitting large power, double-row chains or multi-row chains can be used. The bearing capacity of multi-row chain is proportional to the number of rows. However, due to the influence of precision, the load borne by side-by-side chain is not easy to be uniform, so the number of rows should not be too large.
