摘　　要：针对我国目前在列车中使用的圆柱滚动轴承与轮轴及座孔配合中的问题及其目前实践中采用的原始径向游隙的合理性进行了分析,并提出原始径向游隙的取值,不应一概而论,应随车速、载荷和原始配合大小而取不同值。The article deals with the problem of cooperate of roller bear in g with the axle and the rationality of the original radial windage of roller bea ring in high speed passenger train on the spot in our country at present.And poi nt out :The value of original radial windage of roller bearing should not be the same entirely, which ought to be changed with the speed、 load and original co operate.

关 键 词：列车 滚动轴承 径向工作游隙
