提出了对仅受轴向载荷的高速球轴承进行拟动力学分析以掌握滚动元件运动特性的方法。首先确定了钢球和套圈的滚动速度以及套圈相对于钢球的滑动速度，建立了各滚动元件的润滑模型，阐述了建立高速球轴承运动特性分析基本方程的一般原理。通过求解这些基本方程可得到高速球轴承中各滚动元件的运动状态、受力情况、弹流油膜厚度和疲劳寿命，从而可确定高速球轴承不打滑的最小轴向力。 A quasi-dynamic analysis of high-speed ball bearings subject only to axial load is presented to understand the kinematic characteristics of rolling elements. Firstly, the rolling speed of the steel ball and the ferrule and the sliding speed of the ferrule with respect to the steel ball were determined. The lubrication model of each rolling element was established, and the general principle of establishing the basic equation of the kinematic analysis of the high speed ball bearing was expounded. By solving these basic equations, it is possible to determine the minimum axial force of the high-speed ball bearing without slipping, which can be obtained from the state of motion, force, film thickness and fatigue life of the rolling elements in the high-speed ball bearings.
