Abstract

An overrunning clutch is provided with improved structural characteristics to facilitate the use of grease lubrication. The clutch includes a hub disposed about a rotational axis and defining an inner raceway. A driven member is supported on the hub by a bearing and defines a radially inner surface spaced from the inner raceway of the hub. An outer race is disposed between the inner surface and inner raceway and defines a plurality of cam surfaces opposing the inner race. A plurality of rollers are disposed between the inner raceway and the outer race. Springs urge the rollers into engagement with the cam surfaces in the outer race. A seal is disposed between the rollers and bearing and the inner raceway, cam surfaces, rollers and bearing are lubricated with grease.
