ABSTRACT:
A compact roller spin reduction mechanism for an overrunning roller clutch includes a roller control block that holds each roller, but loosely enough that the block can be thrown out into the pathway and rub on it during overrun. This creates a drag force that opposes the roller energizing spring and reduces pathway traction and its consequent roller spin. The block is sufficiently compact to stay entirely within a wedging pocket as the clutch operates.
