摘要保持架间隙是滚动轴承重要的结构参数之一，直接影响着保持架受力和运动，进一步影响保持架的磨损甚至轴承的寿命。本文在分析轴承保持架间隙与受力关系的基础上，定性分析间隙对保持架磨损的影响。在搭建滚动轴承试验器上开展了保持架间隙对角接触球轴承保持架磨损影响的试验研究。在相同试验条件下对采用不同引导间隙和兜孔间隙保持架的被试轴承进行试验，分析了保持架和钢球表面形貌磨损特征，对比不同保持架间隙（引导间隙、兜孔间隙）条件下保持架与钢球的磨损程度，获得保持架间隙对角接触球轴承保持架磨损的影响规律。试验结果表明，保持架间隙明显影响着保持架兜孔、引导面的磨损，增加引导间隙及兜孔间隙可以降低保持架引导面的磨损。本文研究为保持架间隙的设计与优化提供了理论参考和试验依据。

Abstract：Cage clearances are an important parameter of ball bearings,and they directly affect cage’s force-bearing and motion,and even cage wear and bearing life.Here,based on analyzing the relation between cage clearance and its force-bearing,the effects of cage clearance on cage wear were qualitatively analyzed.Tests were conducted for these effects on a built ball bearing test rig.Under the same test conditions,tests were done for bearings with cages adopting different guiding clearances and pocket ones to analyze morphology wear features of cages and steel ball surfaces,and compare wear degrees of cages and steel ball surfaces under different cage clearances,and obtain the effect laws of cage clearance on its wear in an angular contact ball bearing.The test results showed that cage clearance significantly affects its pocket and guiding surface’s wear; increase in cage’s guiding clearance and pocket one can reduce wear degree of cage guiding surface; the study results provide a theoretical reference and a test basis for ball bearing’s cage clearance design and optimization.
