摘　　要：考虑轴承实际载荷的随机性,将轴承所承受的载荷视作为一个随机变量,利用随机有限元方法对不同轴向游隙时轴承的法向接触应力进行计算,确定最小法向接触应力值所对应的轴向游隙值为最佳游隙值,形成了一种确定圆锥滚子轴承轴向游隙值的方法。以31313轴承为例,利用该方法确定了31313轴承的轴向游隙值。结果表明:与国标中规定的基本游隙值相比,该方法所确定的轴向游隙值对应的接触应力值较小。Considering the randomness of the actual load of the bearings,the loads received by the bearings can be treated as a random variable,Finite element method could be introduced to calculate the normal contact stress of the bearings with different axial play in order to determine that the minimum normal contact stress value corresponding to the axial play is the best value while forming a method to define the axial play in the taper roller bearing.This article takes 31313 bearing as the sample to define its axial play by this method.The results show that：Compared to the basic free play stated in GB,the contact stress corresponding to the axial play defined by this method is smaller.
