Chain drives transmit power up to 100kw and operating peripheral velocity up to 15m/s. The velocity ratio can be as high as 8:1. The main disadvantage of the belt drives and the rope drives is that the velocity ratio does not remain constant, but varies on account of slip. Since chain drives are positive drives there is no slip, hence the ...
