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.
