V ribbed belts feature a series of longitudinal ribs along one side, allowing them to grip the pulleys more effectively than traditional flat belts. The design enhances the surface area contact between the belt and the pulley, thereby reducing slippage and improving power transmission. The belts are typically made from durable materials such as rubber or specialized composites, engineered to withstand the stresses of constant movement and exposure to varying environmental conditions.

The mechanism for varying the pulley diameter can take many forms, including adjustable sheaves or conical pulleys. By changing the effective diameter of the pulleys, the system can alter the speed ratio between the input and output. As the diameter of the driving pulley decreases, the speed of the driven pulley increases, and vice versa. This principle allows for smooth transitions in speed and ensures that the system can operate efficiently under varying loads.
