| 摘 要： | 首先分析了滚动轴承的弹性接触变形能，根据能量守恒原理，提出了轴承变形能与自由落体势能守恒的关联方程，并完成了对轴承冲击动载荷的数值求解. 对于实践中常见的缓冲弹簧-轴承系统，根据弹簧和轴承的刚度比来确定它们各自分担的冲击能量，在此基础上对轴承的动载荷系数进行了计算，文中给出的具体算例与工程实际较为符合. 本文提出的方法可以作为确定轴承冲击载荷的参考依据.

| Abstract: | The elastic contact deformation energy of a rolling bearing is analyzed firstly. Based on the energy conservation law, the impact loads of the rolling bearing under its free falling condition are calculated. The energy distribution between the spring and the bearing is analyzed according to their rigidity ratio in the damping spring-bearing system. The calculated result shows that it is close to the engineering values and can be used as a reference to determine the impact load of bearings. |
