1.序言对于机器设备及其零件,如果不确切了解其使用条件和负荷条件,就不能充分满足并发挥其性能。轴承是一种典型的机械元件,在高速旋转时承受着很大的负荷。为此,轴承公司要很好了解轴承的使用条件,而使用单位则要掌握轴承的性能,以便进行选择,这些都是至关重要的。机车车辆用轴承的维修保养需要很多劳力。由于滑动轴承精度、性能误差较大,现已
1. Preamble For machinery and equipment and parts thereof, their performance and performance can not be fully met without a clear understanding of their conditions of use and loading conditions. Bearings are a typical type of mechanical element that is heavily loaded at high speeds. To this end, the bearing company to well understand the bearing conditions of use, and the use of the unit will have to grasp the performance of the bearing in order to make the choice, which is crucial. Maintenance of rolling stock bearings requires a lot of labor. Due to the precision of the sliding bearing, the performance error is larger now
