摘　　要：四点接触球轴承在合套过程中,其径向游隙的变动量与滚动体直径的变化量并不清晰。为更好地指导轴承生产,对上述关系进行了分析计算。结果表明,四点接触球轴承的径向游隙除受沟底直径与滚动体直径影响外,还与沟曲率半径及沟曲率中心偏心距相关,并且其径向游隙与球径变化量为非直线型的对应关系,在相同球径偏差的情况下,原始接触角越大,径向游隙的变化量也越大,反之亦然。In the process of four point contact ball bearing assembly, the relationship between the variation of [）ear- ing radial clearance and the change quantity of ball diameter is not clear, in order to guide bearing pro- duction better, this paper analyzes and calculates the relationship above. The results show that the ra- dial clearance of the four point contact ball bearing is affected by not only the groove bottom diameter and the diameter of the rolling body, but also the gully radius of curvature and curvature center eccen- tricity. The radial clearance and ball diameter variation is not linear corresponding relation, under the condition of the same ball diameter deviation, the greater the original contact angle, the greater the a- mount of radial clearance change and vice versa.
