One-way roller clutch

摘要

A one-way roller clutch has an inner race, an outer race, a plurality of rollers that are disposed between the races and a cage assembly that is keyed to the outer race. The cage assembly anchors a plurality of energizing springs that bias the rollers toward an engaged position where the rollers are wedged between the races so that one race drives the other. The energizing springs are variable rate springs that produce exponentially increasing spring forces that counteract the centrifugal force of the rollers so as to reduce roller displacement during overrunning and response time for clutch engagement for all operating speeds of the one-way roller clutch.
