摘要

为了研究负载变化对RV减速器摆线针轮啮合特性的影响，考虑摆线轮齿廓修形，利用UG建立摆线针轮机构的三维模型，运用Ansys的瞬态动力学模块分析了摆线针轮在一个啮合传动周期内的啮合齿对数和啮合应力变化情况，并将仿真与理论的接触应力进行了对比。结果表明，仿真与理论的接触应力在整体上趋势一致；摆线针轮的啮合齿对数和啮合应力值均呈现周期性规律，且随着负载的增大而增加；接触应力和等效应力与啮合齿对数的变化趋势相反，摆线针轮啮合齿对数越多，其啮合应力越小。针齿在长度方向上的等效应力随负载增大而增大，应力有均匀分布的趋势但变化较小。有限元分析对RV减速器的设计、分析和制造有一定的参考意义。

Abstract

In order to study the influence of load change on the meshing characteristics of cycloid pinwheel of RV reducer, considering the modification of cycloid tooth profile, the three-dimensional model of cycloid pinwheel mechanism was established by UG. The changes of meshing tooth pairs and meshing stress of cycloid pinwheel in a meshing transmission cycle were analyzed by using the transient dynamics module of Ansys, and the simulation was compared with the theoretical contact stress. Results show that the overall trend of contact stress between simulation and theory is consistent, the number of meshing teeth and meshing stress of cycloid pinwheel show a periodic law, and increase with the increase of load. The change trend of contact stress and equivalent stress is opposite to the number of meshing teeth, the more the number of meshing teeth, the smaller the meshing stress. The equivalent stress of the needle tooth in the length direction increases with the increase of load, and the stress has a trend of uniform distribution, but the change is small. The finite element analysis has certain reference significance for the design, analysis and manufacture of RV reducer.
