摘要
对离散齿谐波传动啮合副进行力学分析,基于变形协调方程计算作用于离散齿上的力,并根据赫兹方程求解啮合副处的接触应力。由离散齿谐波传动的周期性,通过连续取波发生器的输入角值,得到离散齿谐波传动啮合力和接触应力在刚轮齿廓、波发生器和离散齿体上的分布。对刚轮齿廓出现与未出现顶切现象,得到啮合力和接触应力在接触面上的变化趋势,以及传动中出现高啮合力和高接触应力的位置,为进一步的强度校核和结构优化设计提供依据。
Mechanical analysis for the discrete teeth harmonic drive gear pair is carried out. The force on discrete teeth is calculated based on the deformation coordination equation, and the contact stress of meshing pair is obtained by Hertz equation. According to transmission periodicity of the discrete gear harmonic wave and the input angle values of continuous sampling wave generator, the distribution of discrete teeth harmonic drive meshing force and contract stress in rigid tooth profile, tooth wave generator and discrete teeth is obtained. By studying the top cutting phenomena in rigid tooth profiles, the change trend of meshing force and contact stress on the contact surface is found, and positions for high meshing force and high contact stress in transmission are also found, in order to provide reference for further intensity and structure optimization design.
