ABSTRACT:
A radially wedging, frictional overrunning sprag clutch has an inner ring defining an inner sprag track and an outer ring which is concentric with respect to the inner ring and defines an outer sprag track. The nominal radius of the inner track is corrected by subtracting therefrom the compression of the inner ring, at the location of contact with the sprags, caused by a maximum transmissible torque. The nominal radius of the outer track is corrected by adding thereto the expansion of the outer ring, at the location of contact with the sprags, caused by the maximum transmissible torque.
