ABSTRACT:
A curvature of a locus of contact points at a higher torque value is increased such that the torque-dependent characteristic of the working transmission error assumes a minimum value in the vicinity of a working torque value T.sub.1 at the tooth surface position corresponding to the working torque value T.sub.1, in the vicinity of a working torque value T.sub.3 at the tooth surface position corresponding to the working torque value T.sub.3, and in the vicinity of a working torque value T.sub.5 at the tooth surface position corresponding to the working torque value T.sub.5. As a consequence, the change in the working transmission error at the working torque is minimized making it possible to reduce the working transmission error in a wide working torque range.
