ABSTRACT:
The driven pulley is used in a variable-speed belt drive. It includes a clutch for transferring torque from the belt to the main shaft of the driven pulley. The clutch is alternatively movable between a disengaged position where the belt can still be in movement without transferring torque, and an engaged position where the torque is transferred to the main shaft. The clutch is controlled by the winding diameter of the belt. A plurality of rods is also provided for keeping the flanges from rotating relative to each other and for transferring torque from the flanges to a movable plate at the back of the clutch. This driven pulley reduces the wear of the belt, decreases the response time and increases the maximum torque that can be transferred compared with the conventional driven pulleys.
