摘 要: 在套圈表面设计微织构已成为轴承润滑增效的1种有效方法，本文中基于VOF (Volume of fluid)理论建立了
润滑油滴在球轴承内圈织构化表面润湿铺展的三维数值模型，对比分析了油滴在常规内圈滚道和织构化内圈滚道
表面的铺展和润湿特性，剖析了微凹坑织构对润滑油滴铺展的作用机理及影响因素，搭建了液滴动态监测平台与
接触角测量平台，将试验结果与数值分析结果进行对比，验证了数值分析的正确性. 结果表明：织构使轴承内圈表
面润滑油滴接触角减小、铺展长度和铺展面积增大，提高了滚道表面的润湿性；在旋转的内圈滚道表面，织构对润
滑油起到存储和滞留作用，使内圈滚道表面润滑油增加、铺展面积增大，形成更加稳定的润滑薄膜，有利于改善轴
承内圈润滑状况. 轴承转速越高、织构间距越小、润滑油黏度越小以及油滴初速度越大时，润滑油在旋转滚道表面
的铺展面积越大；随着织构深度的增大，油滴铺展面积先增大后减小，40 μm是织构的最佳深度. 该研究对角接触球
轴承内圈织构设计以及润滑增效具有重要参考意义.

Abstract: In high-speed mechanical systems, angular contact ball bearings are key transmission components, its
performance directly affects the stability and lifespan of entire machinery. Oil-air lubrication is the main lubricate way
for angular contact ball bearings, however, due to the centrifugal force, it’s difficult for lubricant oil to maintain on the
inner ringway of bearing, resulting in low lubrication efficiency of bearing. In recent years, the continuous advancement
of microfabrication technology make it more convenient and efficient to machine concave texture through material
removal, and surface texture has become an effective means to improve the lubrication state of friction pairs. In this
study surface texture was designed in the inner ringway of bearings, based on VOF theory, a three-dimensional
numerical model was established for analyzing the wetting and spreading behaviors of lubricant oil droplets on textured
surface of bearing inner ringway. The spreading and wetting characteristics of lubricant oil droplets on conventional and
