The Chain Sprockets are also used for power transmission from one shaft to another where slippage is not admissible, sprocket chains being used instead of belts or ropes and sprocket-wheels instead of pulleys. They can be run at high speed and some forms of chain are so constructed as to be noiseless even at high speed. A chain is used to connect two sprockets. One sprocket is the driver sprocket. The other sprocket is the driven sprocket. Sprockets and chain can be used to change the speed, torque, or original direction of a motor. The Chain Sprockets are very efficient.
