文内着重阐述了如何用回归分析原理探讨单列向心球轴承的径向游隙与轴向游隙之间的相互关系。通过同归分析找出径向——轴向游隙的回归方程式,从而进一步得出能保证满足预先给定的径向游隙合格率要求的轴向游隙取值范围,并以这一范围作为轴向游隙的配套标准用于生产实际,实现了按轴向游隙配套,按径向游隙出厂检验的生产方式。附图1幅，表2个，参考文献3篇。 This paper emphatically expounds how to study the relationship between radial clearance and axial clearance of single row radial ball bearings by using the principle of regression analysis. Through the regression analysis to find the radial - axial clearance of the regression equation to further ensure that to meet the predetermined radial clearance requirements to meet the requirements of the axial clearance range, and in this range As a supporting standard for the axial clearance for the actual production, to achieve the axial clearance supporting, according to the radial clearance factory inspection of production methods.
