【摘要】：采用双面刀盘加工方法,基于假想产形齿条的概念,模拟产形齿条与被加工齿轮啮合过程,推导出非对称圆弧线圆柱齿轮齿面方程。通过Matlab实现齿面的数值仿真与可视化。将有限元网格模型导入ABAQUS中,比较了两组非对称齿廓与对称齿廓的应力结果,证明采用非对称齿廓可以提高齿根弯曲强度。另外,对三组不同刀盘半径的有限元结果进行了比较,分析刀盘半径大小对应力的影响,结果证明刀盘半径增大可以减小齿轮副接触应和弯曲应力。
[Abstract]:Based on the concept of hypothetical shaped rack, the meshing process between shaped rack and machined gear is simulated, and the tooth surface equation of asymmetric circular arc line cylindrical gear is deduced by using the method of double-face cutter head machining. The numerical simulation and visualization of tooth surface are realized by Matlab. The finite element mesh model was introduced into ABAQUS and the stress results of two groups of asymmetric tooth profiles and symmetrical tooth profiles were compared. It was proved that the bending strength of tooth roots could be improved by using asymmetric tooth profiles. In addition, three groups of finite element results of different cutter head radius are compared, and the influence of cutter head radius on stress is analyzed. The results show that the increase of cutter head radius can reduce the contact stress and bending stress of gear pair.
