Tooth Profile Parameters Optimization Design of the Short Flexspline in Harmonic Drive

Peng Pandao;Wu Shangsheng;Yang Qi;School of Mechanical and Automotive Engineering, South China University of Technology;Dongguan Richtek Electronics Co., Ltd.;  
Double-arc tooth profile with common tangent is used as the tooth profile of the short flexspline, based on ANSYS Workbench 14.0 finite element software test platform, the contact model of the flexspline under the action of wave generator is established, utilizing the finite element method solve the stress of flexspline, the experiment scheme of different level combination of tooth profile parameters was designed by orthogonal test and the finite element simulation experiment is carried out, the results of orthogonal test were analyzed by the range analysis method. Simulation and analysis results show that: The maximum stress of the flexspline is different in different level combinations of the tooth profile parameters, it is possible to reduce the stress of the flexspline by optimizing the design of tooth profile parameters; The ratio of tooth thickness is maximum to sensitivity of flexspline maximum stress and is the most critical factor.
