| 摘 要： | 在齿轮传动中,轮齿的弹性变形引起的刚度激励和啮合冲击是齿轮啮合的主要动态激励之一,所以确定轮齿的弹性变形一直是齿轮动力学的重要任务。但是轮齿的弹性变形及其啮合过程变化较复杂,精确计算困难。我们用有限元法对不同齿数、载荷、加载位置及圆角半径的齿轮受载后的弹性变形进行了大量的计算,且将有限元模型多次细化网格作收敛验证,验证结果收敛。将计算数据与实测值进行对比,证明了有限元的准确性和精确性。在详尽分析计算结果的基础上,找出了影响直齿外齿轮变形挠度的6个主要参数,并且将这些参数与变形的关系拟合曲线,找到了相关的规律。

| Abstract: | Because Stiffness excitation and meshing impact caused by elastic deformation of the teeth is mainly one of the dynamic excitation of the gear meshing during gear transmission,how to determine the elastic deformation of gear is one of the important tasks of gear dynamics.However,the elastic deformation of teeth and the mashing process is complicated,it is difficult to calculate the elastic deformation of teeth during the meshing process.In this paper,finite element method is used to calculate elastic deform... |
