本文叙述用滚动轴承静刚度K_S来计算轴承内外座圈与滚动体之间的接触变形的总和。这种计算以往是用古典赫兹接触理论来分析的。该理论用复杂的椭圆积分分别计算外座圈与滚动体之间以及内座圈与滚动体之间的接触变形,然后将它们相加。由于在滚动轴承EHD研究范围内,人们感兴趣的是总接触变形量而无须弄清内外座圈的各自变形量,因此完全可以采用本文所述的方法来计算总变形量,从而避免进行繁复的椭圆积分。本文的计算结果表明,由静刚度K_S所得的结果与赫兹理论分析所得的结果非常接近,其精度足以满足轴承EHD研究的要求。
This paper describes the static stiffness K_S of rolling bearings to calculate the sum of the contact deformation between the inner and outer races and the rolling elements. This calculation has traditionally been analyzed using classical Hertzian theory. This theory calculates the contact deformations between the outer race and the rolling body and between the inner race and the rolling body, respectively, using complex elliptic integrals, and then adds them together. Due to the fact that it is of interest in the EHD research of rolling bearings that the total amount of contact deformations is of interest without having to understand the respective deformations of the inner and outer races, it is entirely possible to calculate the total amount of deformation using the method described in this article to avoid complicated ovals integral. The calculation results of this paper show that the results obtained from the static stiffness K_S are very close to the results obtained from the Hertz theoretical analysis, and their accuracy is sufficient to meet the requirements of the EHD bearing research.
