一、前言一些文献和教材只是介绍了向心推力轴承轴向载荷的计算公式,而关于公式推导的原理介绍得很少,因此学生甚至工程技术人员在计算时,往往是死套公式,并易出错。笔者针对以上情况在教学中介绍了公式推导的原理,以便学生能根据具体受力情况灵活地确定向心推力轴承的轴向载荷。 I. Preface Some literatures and textbooks only introduce the formula for calculating the axial load of radial thrust bearings. However, the principle of formula deduction is rarely introduced. Therefore, students and even engineers and technicians often calculate the dead set formula and are easy to use Wrong. In light of the above situation, the author introduced the principle of formula derivation in teaching so that students can flexibly determine the axial load of radial thrust bearings according to the specific stress conditions.
