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。总结了全齿高对轮齿弯曲应力的影响规律,齿轮的轮齿高度选择h=2.0mn附近时弯曲应力最小,且全齿高选择h=(1.9～2.2)mn时能够保证轮齿受力较小,为双圆弧齿轮的设计和使用提供理论依据。By using ANSYS Parametric Design Language （APDL）, the three - diraensional entity of Double - Arc Helical gears and the corresponding finite element model are set up. This paper analyses the tooth bending stress of Double - Arc Helical Gears, frora which it can be suraraarized that the influencing law of the bending stress of Double - Arc Helical gears of the full tooth height, and having a conclusion that the bending stres is rainum when the full tooth height choosing h = 2.0 ran nearby, furthermore the tooth has little stress when the the whole tooth height choosing h = （ 1.9 - 2.2 ） ran. This paper offers the theoretical foundation for design and use of Double - Arc Helical gears.
