Pulleys serve as integral components in any mechanical system utilizing V-belts. They change the direction of the driving force, facilitate multi-stage drives, and allow adjustments in speed and torque. The construction of a pulley plays a significant role in the overall performance of the V-belt system. Typically made from materials like cast iron or aluminum, pulleys need to have a specific profile that matches the V-belt to ensure optimal interaction and prevent premature failure.
