Abstract

Drive pawl 10 is configured such that its tooth-engaging surface 12 yields an area contact with the engaged surface of the clutch teeth 14. The rear corners of the clutch teeth 16 have had material removed so that they conform to the overrun pawl-engaging surface 18 of overrun pawl 20.

Nonoverrunning Pawl Clutch

Drive pawl 10 is configured such that its tooth-engaging surface 12 yields an area contact with the engaged surface of the clutch teeth 14. The rear corners of the clutch teeth 16 have had material removed so that they conform to the overrun pawl-engaging surface 18 of overrun pawl 20.

By removing the back corner of tooth 16 and conforming the surfaces 12 and 18 to engage in area contact, forces are reduced, and this reduces vibration, impact and the breaking of parts. The removal of the back slope of the teeth 16 facilitates an earlier entry of pawl 10 into the inter-tooth gap, thus allowing a more positive engagement.
