我们对1985年进口的ND_2型机车牵引电动机非传动端轴承进行了打开轴承盖检查轴承状况的工作。所检查的67台电机中有29台电机轴承配合游隙≤0.04,而段规要求不小于0.05。下面谈谈对于配合游隙小于规定值的问题应怎么看及有什么危害。所谓游隙就是轴承滚动体与滚道之间的间隙。轴承游隙分为基本组和辅助组。国产轴承 We imported 1985 ND2 locomotive traction motor non-drive-end bearings to open the bearing cover to check the status of the work of the bearing. Of the 67 checked motors, 29 are equipped with motor bearings with clearance of ≤0.04 and the gauge requirements of not less than 0.05. Here to talk about with the clearance of less than the value of the problem should be how to see and what harm. The so-called clearance is the gap between the rolling bearing and the raceway. Bearing clearance is divided into basic group and auxiliary group. Domestic bearings
