摘要

针对轮边减速系统大承载、长寿命的发展要求，提出一种对数修形复合滚柱活齿结构。结合当前对空心滚柱接触变形的研究，通过引入设计参数,Δ,c,和,Δ,e,，提出了一种计算对数修形复合滚柱啮合变形量的方法，分析了填充度和不同滚柱对啮合刚度的影响规律，利用有限元方法对不同滚柱啮合线处的等效应力分布进行了对比分析。结果表明，相同载荷条件下，对数修形复合滚柱活齿的啮合刚度略高于空心滚柱活齿的啮合刚度，且随填充度增大，啮合刚度减小；对数修形复合滚柱可有效改善边缘应力集中现象，使最大等效应力明显降低。

Abstract

Aiming at the development requirements of large load capacity and long life of wheel-side deceleration system， a logarithmic modified composite roller movable tooth transmission is proposed. Combined with the current research on the contact deformation of hollow roller， a method for calculating the meshing deformation of logarithmic modified composite roller is proposed by introducing design parameters ,Δ,c, and ,Δ,e,., The influence of filling degree and different rollers on meshing stiffness is analyzed. The finite element method is used to compare and analyze the equivalent stress distribution of different rollers. The results show that under the same load conditions， the meshing stiffness of the logarithmic modified composite roller movable tooth is slightly higher than that of the hollow roller， and the meshing stiffness decreases with the increase of the filling degree. The logarithmic modified composite roller can effectively improve the edge stress concentration and reduce the maximum equivalent stress.
