摘要

首先通过实测获得了一系列具有横向纹理的表面粗糙度数据;其次,借助傅里叶非线性变换拟合出粗糙度函数,并将其叠加到油膜厚度方程中形成了滚动轴承混合热弹流润滑模型;基于此模型,在固定滚动轴承参数不变的前提下,通过改变接触表面粗糙度之值共进行了45组数值计算;然后,通过对计算结果的回归分析,分别建立了内圈与滚动体接触点处的平均油膜厚度及次表面主剪应力最大值与粗糙度之间的定量关系。

Abstract

The surface roughness data of test-pieces with transverse profiles were firstly measured by a roughness profile measuring analyzer. With the help of the Fourier nonlinear approximation the measured data was used to form a roughness function which was superimposed to film thickness equation and a mixed thermal elastohydrodynamic lubrication model for the rolling bearing was then established. Based on the model,45 sets of numerical calculations were carried out by changing the roughness values under other conditions of the rolling bearing were fixed. Then the two quantitative relationships between the average oil film at the contact point and the roughness as well as the maximum subsurface principal stress and the roughness are respectively established through the regression analysis of the calculation results.
