Chain drives are the most important drives for the transmission of power. It is a positive drives system unlike self-drives. The velocity ratio of chain drives, i.e., ratio of angular velocity of the driving sprocket wheel remains constant with no slip and no creep. The velocity ratio in this case is as high as 8 which are quite high. Figure [...]
