铁道机车车辆上使用的车轴轴承一旦发生事故,不仅会引起轴承损伤,而且有可能妨碍列车运行安全,为确保列车运行的高可靠性与安全性,对车辆轴承要求具备各种性能。本文从说明车轴轴承的结构入手,介绍了对车轴轴承要求的性能,阐述了检查车轴轴承各种性能的方法,例如车轴轴承性能试验方法、车轴轴承上承载载荷的推测方法等。
In the event of an axle bearing used on a railway rolling stock vehicle, it not only causes bearing damage, but also may hinder the safe operation of the train. To ensure the high reliability and safety of the train running, various functions are required for the bearing of the railway vehicle. This paper begins with the explanation of the structure of the axle bearing, introduces the required performance of the axle bearing, and expounds the methods of checking the performance of the axle bearing, such as the test method of the axle bearing and the method of estimating the bearing load on the axle bearing.
