Double-width pulley's working principle

Working Principle

• Similar to single - width pulleys, double - width pulleys operate based on the principle of friction between the belt and the pulley's groove. When a belt is placed in the groove and the pulley rotates, the frictional force between the belt and the pulley causes the belt to move, transferring power from one shaft to another.
• In applications where multiple belts are used in the double - width pulley, each belt contributes to the overall power transmission, increasing the load - carrying capacity and the efficiency of the system.
