摘要

基于滚柱包络端面啮合蜗杆传动的传动理论与等温弹流润滑理论，考虑表面波状粗糙度的影响，采用数值分析方法着重分析了传动副不同啮合位置、粗糙度幅值、滚柱半径以及喉径系数对弹流润滑性能的影响。结果表明，传动副啮出位置蜗轮齿顶处润滑性能最差；粗糙度幅值、滚柱半径、喉径系数的增加均对润滑性能产生正面影响，会使油膜厚度增加、油膜压力下降。

Abstract

Based on the transmission theory of single roller enveloping end face meshing worm drive and isothermal elastohydrodynamic lubrication theory， and considering the influence of surface wavy roughness， a numerical analysis method is adopted to analyze the influence of different meshing positions， roughness amplitude， roller radius and throat diameter coefficient on the elastohydrodynamic lubrication performance of transmission pair. The results show that the lubrication performance is the worst at the top of the worm gear at the meshing position of the transmission pair， and the increase of roughness amplitude， roller radius and throat diameter coefficient has a positive effect on the lubrication performance， and makes the oil film thickness increase and the oil film pressure decrease.
