RV减速器摆线针轮的有限元接触分析

基于有限元分析方法,研究加载状况下摆线针轮啮合副初始啮合时齿廓对的接触状态。考虑摆线针轮啮合副的齿廓修形和摆线轮齿廓线的建模精度,利用ANSYS自带的APDL语言建立了摆线针轮啮合副的三维模型。考虑有限元网格质量及有限元模型的计算效率,利用VSWEEP命令生成了有限元模型并局部细化了网格。最后考虑摆线针轮的实际工况,建立了摆线针轮的接触对和边界条件。分析结果表明:摆线针轮初始啮合瞬间一共有6个齿参与传力,其中最先接触齿为第6齿,并且在啮合齿廓对附近摆线轮齿及销孔变形比较大。

Contact Analysis of Cycloidal Pin Wheel of RV Reducer Based on Finite Element

Based on the finite element analysis method, the contact state of the tooth pairs during the initial meshing of the cycloidal pin wheel was studied. By considering the profile modification of the cycloidal pin gear pair and the modeling accuracy of the cycloidal gear tooth profile, the three dimensional model of the cycloidal pin wheel pair was established by using the APDL language provided in ANSYS. Then, by considering the finite element mesh quality and the computational efficiency of the finite element model, the finite element model was generated by using the VSWEEP command and the mesh was refined locally. Finally, by considering the actual working condition of the cycloidal pin wheel, the contact pair and boundary conditions of the cycloidal pin wheel were established. The analysis results show that there are 6 teeth in the initial meshing moment of the cycloidal pin wheel to participate in the force transmission. The first contact tooth is the 6th tooth, and the deformation of the cycloidal tooth and pin hole in the vicinity of the meshing tooth pairs is relatively large.
