Pulley is a mechanical device that is used as a support for the movement of the belt or belt circumference to run a groove force that serves to deliver a power. Pulleys are often used to change the direction of the applied force and transmit rotational motion.
Pulley Function
Puli has functions, among others:
1. Transmit power from drive to driven component
2. Reducing rotation
3. Speed up the spin
4. Increase torque
5. Reduce torque.
