Chain drive VS belt drive and drive wheels
Compared to belt drive
The sprocket transmission has no elastic sliding and slippage and can maintain an accurate average transmission ratio; Able to work in harsh environments such as high temperature and oil pollution.
Compared with gear transmission
The manufacturing and installation accuracy is low, and the transmission structure is simple when the center distance is large.
Disadvantage: The instantaneous speed and instantaneous transmission ratio are not constant, the smoothness of the transmission is not good,with impact and noise as well.
