在铁道车辆中,滚动轴承用作走行装置的车轴轴承及动力发生和传递的牵引电动机和驱动装置等的轴承,分别发挥着重要作用。这些轴承的故障对车辆的运行影响很大,因此,对滚动轴承的设计、生产和维护一向都特别重视。另外,各轴承在载荷、转速和润滑方法等方面不尽相同。本文在叙述各轴承特点的同时,就与高速化、轻量小型化、减少维护和提高耐久性等车辆新理念相适应的轴承和润滑技术进行了介绍。
In railway vehicles, rolling bearings are used as axle bearings for traveling gears and as bearings for traction motors and drives for power generation and transmission, each of which plays an important role. The failure of these bearings has a great impact on the operation of the vehicle, therefore, the design, production and maintenance of rolling bearings have always been given special attention. In addition, the bearings in the load, speed and lubrication methods are not the same. This article describes the characteristics of the bearings at the same time, on the speed and lightweight miniaturization, reduce maintenance and improve durability and other new concepts compatible with the bearings and lubrication technology are introduced.
