货车轮轴是铁路货车上重要的部件,承担着货车导向、承载、走行的功能,是直接关系到铁路货车安全的关键部件,因此,货车轮轴一旦出现故障将直接危及铁路货车的行车安全。本文通过对2014年第4季度全路几起铁路货车轴承故障情况的调查,阐明了货车轴承密封罩脱出是引起货车热轴故障的重要原因,同时根据这几起轴承故障调查处理结果,以及笔者从事轴承检修技术管理和轴承检修验收工作的经验,分析轴承密封罩脱出的直接原因,进而从轴承检修和使用等方面,对货车段修单位强化轴承检修质量,防止轴承密封罩脱出提出几点意见。
The axle of a truck is an important component of a railway wagon. It undertakes the function of guiding, carrying and walking of the wagon. It is a key component that is directly related to the safety of railway wagons. Therefore, once a wagon axle malfunctions, it will directly endanger the safety of wagons. Based on the investigation of several railway freight car bearing failures in the 4th quarter of 2014, this paper illustrates that the out-of-truck lid seal is an important cause of the hot axle failure of the truck. Based on the investigation and treatment results of these bearing failures, Engaged in bearing maintenance technology management and bearing inspection and acceptance of work experience, analysis of the bearing seal cover prolapse of the direct cause, and then from the bearing overhaul and use, etc., on the trucking unit to enhance the quality of bearing overhaul, to prevent the bearing seal cap prolapse made a few comments .
