高速铁道车辆滚动轴承的原始配合和原始径向游隙之研究

Analysis on the Matching and Original Centripetal Oearance of Cylinder Bearing of High - speed Locomotive

对我国高速铁道车辆中使用的滚动轴承与轮轴的原始配合,以及目前在实践中,采用的滚动轴承原始径向游隙的合理性进行了分析,指出原始径向游隙的取值应随车速、载荷、路况和原始配合大小而取不同值。

The paper analysized the problem happening in matching between axle and bearing used in current railway passenger train in China, and pointed out the value of the original clearance of the bearing should not be constant and be variable according to the speed of train and the load.
