ABSTRACT:
An overrunning clutch comprises a hollow drive shaft, a driven shaft including a large diameter portion and a small diameter portion loosely fit in the drive shaft, a cylindrical body having an inner peripheral surface in which cam surfaces are formed to function as an overrunning clutch and being splined to one end of the large diameter portion adjacent to the small diameter portion of the driven shaft, a retainer held within the cylindrical body, rollers held in roller pockets of the retainer, springs disposed in the roller pockets of the retainer to urge the roller, an annular abutment plate fit around the small diameter portion of the driven shaft and adapted to position the cylindrical body, and a fixing member fit around the small diameter portion of the driven shaft and adapted to fix the annular abutment plate in place. The overrunning clutch is thus simple and strong, and prevents "dancing phenomenon" of the rollers by firmly holding the rollers in such a position that the rollers are free to race.
