摘要: 本文采用有限元应力影响矩阵法研究了高重合度弧齿锥齿轮在多种误差和载荷条件下的弯曲应力状态, 证明了经过优化设计的高重合度弧齿锥齿轮不仅有良好的动态性能。Abstract: In this paper,the bending stress states of HCR (High Contact Ratio) spiral bevel gears in conditions of various errors and loads have been studied by applying the FEM (Finite Element Method) and stress influencing matrix technique.The calculated results have showed that the high bending strength could be obtained in transmitting of HCR spiral bevel gears in a certain error allowance by optimal design of tooth surface topology,as well as favourable dynamic behavior.
