ABSTRACT:
A drive apparatus for driving the auxiliary equipment of an automobile engine or other motor is disclosed. It comprises a rotating input shaft which is connected to the crankshaft of an engine and on which is rotatably mounted a drive pulley which belt-drives auxiliary equipment. A planetary cone reduction gear is housed inside the pulley and transmits drive force from the input shaft to the pulley. A mechanism for adjusting the reduction ratio of the reduction gear operates in response to centrifugal force to reduce the reduction ratio of the reduction gear as the speed of the input shaft increases. The adjusting mechanism comprises a gear whose center of gravity is eccentric with respect to its rotational center and a cylindrical cam which is rotated by the rotation of the gear and whose rotation exerts a longitudinally-directed force on a speed change ring of the reduction gear.
