从大连内燃机车研究所内燃机车数据库中提取了1986～1993年在我国运用的几种车型的牵引电动机抱轴承机玻、临修故障统计数据。从中可以看出，故障率较高的有东民、东风8、ND2等型机车。以东风4型机车为例，概述了故障的发生原因及其防止对策。并介绍了抱轴承的开发动向。 From the diesel locomotive database of Dalian Diesel Locomotive Research Institute extracted from 1986 to 1993 in our country several models of traction motor bearings bearing glass, temporary repair failure statistics. It can be seen that the higher the failure rate is Dongmin, Dongfeng 8, ND2 and other locomotives. Taking Dongfeng 4 locomotive as an example, the causes of failure and their countermeasures are summarized. And introduced the development trend of the bearing.
