Abstract

A mechanical speed change device designed to occupy minimum space in the ial direction. In operation, a ball type cam follower simultaneously tracks sinuous cam grooves in the drive and driven members. The lead angles of the respective cam grooves are different so that a given axial displacement of the cam follower requires different rotational movements of the drive and driven members. Therefore a given rotational speed of the drive member produces a different rotational speed of the driven member.
