摘要
A harmonic drive includes a rigid internal gear, a flexible external gear meshed with the rigid internal gear, and a wave generator abutted against the flexible external gear. Through a special parameter setting to design the outer peripheral edge of the wave generator in a surface of variable curvature, the contact area between the wave generator and the flexible external gear is increased to improve fretting wear, thereby enhancing transmission accuracy and reducing hysteresis error.
