摘　　要：利用ANSYS的参数化设计语言(APDL)建立双圆弧齿轮的三维实体,形成相应有限元模型,对轮齿弯曲应力进行了分析。总结了名义压力角和齿形工艺角对轮齿弯曲应力的影响规律,并得出跑合前最大弯曲应力发生在齿腰处的结论,为双圆弧齿轮的设计和使用提供理论依据。Using the ANSYS Parametric Design Language (APDL) to establish 3D entity of double-arced gear and forming a corresponding finite element model so as to carry out an analysis on the bending stress of gear. The influence law of gear's bending stress affected by nominal pressure angle and technological angle of tooth profile has been summarized and obtained a conclusion that the maximum bending stress before running-in period occurred at the waist place of the tooth, thus provided a theoretical foundation for the design and application of double arced gears.
