Like the centrifugal clutch with automatic belt tensioner, the centrifugal clutch with variable speed pulley offers the advantage of compact design, which eliminates the need for an additional tensioner pulley in the belt drive.
In the centrifugal clutch with variable speed pulley, the drum is designed as a variable speed hub. The belt pretension is adjusted with the regulating nut. The regulating nut is secured by grub screws, and the adjustment range is infinitely variable. These centrifugal clutches are also used in vibratory plates.
