Abstract
针对采用圆弧修缘素线圆柱滚子轴承试验过程中出现的滚子表面剥落问题，采用宏观检查、微观分析、金相和硬度检验以及尺寸测量等方法对失效圆柱滚子进行了分析。结果表明，修缘滚子直线部分与圆弧处不圆滑过渡是导致其剥落的主要原因。经工艺改进后轴承工作正常，性能良好。
Aiming at the surface spalling on rollers during experiment for arc edge trimming generatrix cylindrical roller bearings,the failure roller is analyzed by using macro inspection,micro analysis,metallographic and hardness test and dimension measuring method.The results show that the unsmooth transition between straight part and arc of the roller are main reason of spalling.The improved bearings work normally and perform well.
