Belt and rope drives.
The belts or ropes are used to transmit power from one shaft to another by means of pulleys which rotate at the same speed or at different speeds.

Chain drive ex.
Small pulley transmits 2 hp at 2450.
The amount of power transmitted depends upon the following factors.
The tension under which the belt is placed on the pulleys.
The belts or ropes are used to transmit power from one shaft to another by means of pulleys which rotate at the same speed or at different speeds.
The rope runs over a grooved pulley.
Rope drives use a number of circular section ropes rather than a single flat or vee belt.
