What are the advantages and disadvantages of chain drive compared with belt drive?

Compared with belt drive, chain drive is meshing drive, which can keep accurate average transmission ratio; The required tension is small, and the pressure acting on the shaft is also small, which can reduce the stress on the shaft and bearing; Compact structure; Can work in harsh environments such as high temperature and oil pollution.

Compared with gear transmission, chain transmission requires lower manufacturing and installation accuracy. When the center distance is large, its transmission structure is simple and the cost is low.

The main disadvantage of chain drive is that the instantaneous chain speed and instantaneous transmission ratio are not constant, so the transmission stability is poor, and there is some impact and noise in the work, so it can not be used at high speed.
