Total meshing area changing disciplinarian of work meshing pair of oscillating-teeth end-face harmonic gear

Oscillating-teeth end-face harmonic gear is of an advanced drive wheel suitable for large power and high transmission ratio system. It has a broad prospect of application. The paper introduces transmission types of oscillating-teeth end-face harmonic gear, and analyses different transmission types of oscillating-teeth end-face harmonic gear´s meshing process, summarizes evolution of total meshing area of oscillating-teeth end-face harmonic gear´s work meshing pair. This research provides a theoretical basis for further discussion to bearing capacity of oscillating-teeth end-face harmonic gear´s work meshing pair.
