Abstract

A centrifugally-actuated roller clutch or overrunning clutch acting to engage two shafts rotating independently at different speeds to bring them into engagement in one or both directions at a predetermined rpm. The clutch assembly includes an outer race, a wave hub or inner race, clutch rollers, a spacer ring or spacer blocks to separate the rollers and a garter spring encompassing the rollers. If a freewheeling mode is required in one direction, the spacer ring or blocks are not required, and the wave form of the inner hub controls the overrunning action.
