一种汽车发电机轴承异响问题分析与解决方案

An analysis and solution to the noise of automobile generator bearing

针对发电机轴承外圈滚道因电蚀剥落引起的异响问题,采用光学显微镜、扫描电子显微镜、红外光谱、洛氏硬度测试等方法对发电机轴承进行分析,依据检测结果及原因分析通过更改发电机轴承润滑脂解决电蚀问题。

In view of the noise caused by the peeling off form the outer race of the generator bearing,the optical microscope,scanning electron microscope,infrared spectrum,Rockwell hardness test and other methods are used to analyze the generator bearing.According to the test results and cause analysis,the problem of electric erosion is solved by changing the lubricating grease of the generator bearing.
