Optimal Design of Meshing Parameter in Harmonic Gear Drive

A mathematics model of gear backlash was established in order to minimize the backlash of harmonic transmission.The model established based on compensates backlash in the way of flexspline add retorted angle,so the model is more precise than former which compensates for putting backlash decrease volume directly into object function backlash value.An optimization design analysis of four forces model harmonic gear drive by the new method was given.And the result parameters can be used for harmonic gear manufacture.
