Analysis of the stiffness influence factors of face gear tooth based on ANSYS

面齿轮轮齿刚度是面齿轮传动动态分析及优化设计的重要参数,面齿轮设计参数对其轮齿刚度有重要影响。建立了面齿轮传动模型,运用有限元分析软件Ansys Workbench和Ansys Classic对面齿轮不同啮合点处的轮齿刚度进行了联合仿真,研究了面齿轮主要设计参数对其轮齿刚度的影响。结果表明:面齿轮轮齿刚度沿齿根到齿顶方向逐渐减小,随着面齿轮模数、压力角及齿宽的增大而相应增大;面齿轮轮齿刚度沿齿根到齿顶的变化率随着模数的增大而变小,随着齿宽的增大而增大,而压力角对其变化率基本没有影响。

Tooth stiffness of face gear is the main parameter of dynamic analysis and optimization design for face gear transmis- sion, and the design parameters of face gear have important influence on the stiffness of face gear tooth. The finite element analy- ses about the tooth＇ s stiffness of different meshing points are made based on Ansys Workbench and Ansys Classic. It researched that analysis of influence of tooth＇ s stiffness by main design parameters of face gear. From the results, the conclusions can be ob- tained as follow： Tooth＇ s stiffness of face gear decreases along the direction of tooth root to the tip gradually, and tooth＇ s stiffness increases with the increase of module, pressure Angle, tooth width ; the changing ratio of tooth＇ s stiffness along the tooth root to the tip increases with the decrease of module, as the tooth width increases, the pressure angle doesn＇ t much affect on the changing ratio.
