Features of chain drive:

1) Compared with the belt drive, there is no elastic sliding, it can maintain an accurate average transmission ratio, and the transmission efficiency is higher; the chain does not require large tension, so the load on the shaft and the bearing is small; it will not slip and the transmission is reliable, Strong overload capacity, can work well at low speed and heavy load;

2) Compared with gear transmission, it can have a larger center distance, can work in high temperature and dusty environments, and has lower cost;

3) The disadvantage is that the instantaneous chain speed and instantaneous transmission ratio are changing, the transmission stability is poor, there is impact and noise in the work, it is not suitable for high-speed occasions, and it is not suitable for frequent changes in the direction of rotation.
