某型号国产牵引电机轴承寿命对比试验

Life comparison test for a domestic traction motor bearing

介绍了某型号国产牵引电机轴承与国外进口牵引电机轴承寿命对比试验方案,包括试验主体结构、试验头组件及试验润滑原理及方法等,并通过对试验数据及试验结果的全面对比,分析两种轴承的性能差异。试验结果对比表明,国产与进口牵引电机轴承在各项性能指标上无明显差别。

This paper introduces the test scheme of the life comparison test for the domestic and the imported foreign traction motor bearing, including the main structure of the tester, the bearing head and the test lubrication principle and method,etc,and through a comprehensive comparison of the test data and test results,the two kinds of bearing performance differences are analyzed. The test results show that domestic and imported traction motor bearing has no obvious difference on the various performance indicators.
