| 摘 要： | 针对少齿差行星齿轮传动时的多齿啮合效应,采用有限元法建立了渐开线少齿差多齿啮合模型,分析了动态轮齿的接触特性分析,得到了完整啮合周期内齿面接触应力、齿面印痕、齿面滑动位移等啮合特性参数,分析了啮入、啮出冲击对齿顶刮行的影响。采用长修形法对少齿差行星传动的齿轮进行齿廓修形,使轮齿啮合状况得到了改善,明显减小了啮合冲击对齿顶刮行的影响,研究结果对指导少齿差行星齿轮传动设计具有重要意义。

| Abstract: | In view of multi-tooth meshing of planetary gear drive with small tooth number difference,a finite element analysis model was built and each node’s contact stress,status,sliding distance,etc.,in the whole meshing process were obtained.The meshing impact’s influence on scraping tooth top was analyzed.By profile modification,meshing status improved and meshing impact lightened,which is of instructive significance for designing gear drive with small tooth number difference. |
