摘要
通过对383台次DF4B型机车中修待装牵引电动机92417型轴承的检测数据的统计分析,结合本段检修、运用特点,确定出92417型轴承较为合理的检测门限值,为该型轴承的检测提供了判定依据。
According to the detection data and the statistic analysis of 92417 type bearings of the traction motors which have been overhauled for standby on a total of 383 DF 4B locomotives,the reasonable detection threshold value of the 92417 type bearings is determined considering the maintenance and operation characteristics.It gives a judging basis for detecting this kind of bearing.
