To accurately predict the dynamic behaviors of high speed ball bearings, an investigation on the sliding behavior of balls at high and low speeds, and light and heavy loads is necessary. However, existing nonlinear dynamic models fail to consider comprehensively key factors such as asperity and hydrodynamic tractions, time-varying friction coefficient and time-varying lubricant mode. In this work, these influencing factors are integrated into the nonlinear dynamic model to make it suitable for the working conditions of high and low speeds and light and heavy loads. The dynamic analysis provides the relation of angular speeds of balls with spin and sliding at light and heavy loads, also it reveals the number of pure rolling point under the combined effect of differential sliding and spin sliding. Research results provide a reliable mathematical model and theoretical bases for further studying the dynamic behaviors of high speed ball bearings.

为了准确预测高速球轴承的动态行为，需要对滚珠在高速和低速、轻载和重载下的滑动行为进行研究。然而，现有的非线性动力学模型未能综合考虑粗糙度和水动力牵引、时变摩擦系数和时变润滑模式等关键因素。在这项工作中，将这些影响因素整合到非线性动力学模型中，使其适用于高低速和轻重负载的工况。动力学分析给出了轻载和重载下球的角速度与自旋和滑动的关系，揭示了在差动滑动和自旋滑动共同作用下的纯滚动点数。
