The Meshing Researches On Asymmetrical Tooth Shape Of Oscillating-teeth End-face Harmonic Gear

The end face harmonic gear drive of oscillating teeth belongs to the three dimensional space oscillating teeth gear drive. It overcomes the contradiction between the deformation and bearing capacity of the flexible wheel of the common harmonic gear drive, and it contains the advantages of the common harmonic gear drive and the oscillating teeth drive, but the transmitted power of the end face harmonic gear drive is enhanced enormously. The new kind of transmission theory introduced in this article has been applied for patent (the application number is 200410012992.6).In the paper, it introduced the structure and working principles of oscillating-teeth end-face harmonic gear, as well as its types and classification basing on statement on structure and development of oscillating drive and harmonic drive. It gives great importance at Unsymmetrical Tooth Shape. At last, it deduced the equations of teeth of all key components, such as end face gear, oscillating teeth, wave producer also give the modification equations of end face gear and wave producer.(1) In the paper, it gives the concept of Asymmetrical Tooth Shape, numbered up a few of common asymmetrical tooth shape, and chose different types of asymmetrical tooth shape with different actual need.(2) This article has analyzed different types of the asymmetrical tooth shape in the single tooth transmission and the multi-tooth transmission, proposed the asymmetrical tooth profile several kind of questions which needs to pay attention in the application.(3) At the basic of researching of symmetry tooth shape equation research foundation, it further researched the asymmetrical tooth profile tooth face equation as well as end face gear, wave producer gear tooth face equation.(4) At the basic of researching of symmetry tooth shape modifying, it further researched the tooth shape modifying of end face gear and wave producer with asymmetrical tooth shape tooth modifying as well as the gear tooth face equation of modify end face gear and wave producer.Besides, the asymmetrical tooth of the end face harmonic gear drive of oscillating teeth interrelated subjects which will be researched further of are discussed in this paper, it provides good basis for the manufacture and popularization of the new kind of the oscillating teeth drive.
