ABSTRACT:
A variable diameter pulley including a pair of pulley flanges axially displaceable one relative to the other, centrifugally responsive weights acting on one flange to cause axial displacement thereof, a pusher ring interposed between the actuating weights and the axially displaceable flange, a drive device transmitting the rotation to the weights and the axially displaceable pulley flange. This variable diameter pulley is characterized by providing an axial stop to produce a minimum clearance between the pulley flanges and removable shims to adjust the spacing between the pulley flanges in relation to the wear of a belt engaged in this spacing.
