摘要

工业机器人精密减速器的传动精度和动态稳定性在很大程度上取决于摆线针轮的啮合性能。通过Creo和ANSYS Workbench相结合的数字化设计与动力学分析平台，对精密减速器第二级减速机构的摆线针轮啮合传动部分进行了三维参数化建模和瞬态动力学分析，快速、准确地获得研究所需的精密减速器参数化模型和摆线针轮动态啮合过程中摆线轮齿表面的应力和应变云图，从而得出摆线针轮在啮合过程中接触应力分布规律。采用Hertz接触理论得出的理论计算结果与上述仿真结果进行对比分析，验证了所建模型的正确性，为摆线轮进一步的齿廓优化修形提供了必要的理论基础。

Abstract

Transmission accuracy and dynamic stability of industrial robots precision reducer depend on the meshing performance of cycloid pin gear to a great extent. Therefore， 3D parametric modeling and transient dynamics analysis are carried out on the meshing transmission part of cycloid pin gear in the second stage of the precision reducer through the digital design and dynamics analysis platform combined with Creo and ANSYS Workbench， the model of precise reducer parameter and the stress and strain nephogram of cycloid pin gear tooth surface during dynamic meshing of cycloid needle wheel can be obtained quickly and accurately， thus the contact stress distribution law of cycloid and pin wheel in meshing process is obtained. The theoretical calculation results of Hertz contact theory are compared with the above simulation results， the correctness of the model is verified， which provides the necessary theoretical basis for the cycloid gear tooth profile optimization and modification.
