Transmission chain varieties and characteristics of the introduction

Transmission chain type:

Chain can be divided into drive chain, lifting chain and traction chain. Lifting chains and traction chains are used to lift iron chains and transport machinery, and transmission chains are widely used in general mechanical transmission, and this chapter only describes transmission chains. The transmission chain can be divided into roller chain and toothed chain.

Chain drive consists of a chain and a sprocket mounted on a parallel shaft, and transmits motion and power through the continuous meshing of the chain and sprocket teeth.

Transmission chain features:

1) Compared with the belt drive, there is no elastic sliding, can adhere to the accurate uniform transmission ratio, and the chain power of the transmission rolling door machine is higher; The chain does not require large tensioning force, so the load on the shaft and bearing is small; Will not slip, reliable transmission, overload capacity is strong, can work better under low speed and heavy load;

2) Compared with gear drive, it can have a larger center distance, can work in high temperature environment and dusty environment, and the cost is low;

3) The defect is that the instantaneous chain speed and instantaneous transmission ratio are changed, the transmission smoothness is poor, there is impact and noise in the operation, it is not suitable for high-speed occasions, and it is not suitable for the situation of frequent changes in the rolling direction.
