High speed clutch design with jaw tooth profile to reduce separating load

摘要

A shaft for a clutch member comprises an engagement portion having a plurality of teeth spaced about a shaft centerline. The teeth have a tooth profile with a negative rake angle. The negative rake angle is between 1° and 2°. The teeth have a chamfer angle between the face of the negative rake and the face of the clutch end surface. The chamfer angle is between 65° and 75°. A rotor assembly for a generator, a generator and a method are also disclosed and claimed.
