摘　　要：弧齿锥齿轮工作时齿面接触应力的大小直接影响其使用寿命和安全。本文运用自主开发的弧齿锥齿轮设计分析系统建立齿轮的轮齿网格模型,将模型数据变换后导入ANSYS软件中,经过装配和结构扩展进行轮齿的接触应力分析,得到了多齿对接触情况下,齿面等效接触应力的分布及其变化规律。When a spiral bevel gear is working, its tooth contact stress has direct effect on its service life and safety. We establish the gear＇s mesh model with the gear design and analysis system designed by our group. Then we convert the data of the model and introduce them into the ANSYS software. After assembly and structural expansion, the model is used to do the contact stress analysis of the spiral bevel gear. We thus obtain the distribution and change of its tooth contact stress while several pairs of teeth are meshed.
