本文介绍了当今世界各国典型的机车、动车及高速列车上轴承装置的先进设计;介绍了用于牵引电动机、轴箱、牵引齿轮传动装置和抱轴轴承装置的结构;介绍了延长换油周期、轴承滚子型线的优化、轴承材料选用、尼龙保持架使用等情况;并以 ICE 等高速列车为例,介绍了各个部位轴承应用的成功经验:包括型号、尺寸、游隙、油脂和密封型式的选择等。 This paper introduces the advanced design of bearing devices on locomotives, moving cars and high-speed trains of all countries in the world today. It introduces the structure of the bearing devices for traction motors, axleboxes, traction gear drives and suspension bearings. The optimization of bearing roller profile, selection of bearing materials and the use of nylon cages. The successful experience of bearing application in all parts is also given by using high-speed trains such as ICE. The models include the model, size, clearance, grease and seal type Choice and so on.
