Pulleys and gears are used to transfer rotary motion from one place to another or can be used to lift heavy loads. The pulley has a groove in the rim, in which a belt or rope can run.
It can be used as a belt and pulley system in which two or more pulleys in common to a belt. This allows for mechanical power, torque, and speed to be transmitted across axles. If the pulleys are of differing diameters, a mechanical advantage is realized.
It can also be used as a conveyor pulley which changes the direction of the belt in a conveyor system, to drive the belt, and to tension the belt.
