ABSTRACT:
A variable speed drive that uses cone clutch surfaces, and an adjusting manism for shifting certain ones of the cone surfaces parallel to the cone angle, thereby changing the speed ratio between the input and output members. The engaged clutch surfaces preferably comprise a relatively small diameter male clutch surface engaged with a relatively large diameter female clutch surface, such that a relatively large area engagement is achieved in all adjusted positions of the clutch system. The inventive system preferably includes an intermediate member between the input and output members; this intermediate member has two sets of clutch surfaces interengaged with clutch surfaces on the input and output members to produce a two step speed change from the input member to the output member.
