在承受振动的轴承中，滚动体、轴承套圈，特别是轴承保持架承受振动惯性力所引起的附加载荷，而且保持架承受的部分惯性力对轴承的工作能力有很大影响。文中介绍了定量计算轴承动力学性能、功率损失、轴承温度和保持架承载能力的计算程序，并且阐述了保持架结构对这些参数的影响。 In bearings subjected to vibration, the rolling elements, the bearing rings and, in particular, the bearing cage are subjected to an additional load due to the vibrational inertia force, and the part of the inertial force which the cage takes up greatly influences the working ability of the bearing. The calculation procedure for quantitatively calculating bearing dynamic performance, power loss, bearing temperature and cage bearing capacity is presented in this paper. The influence of cage structure on these parameters is also presented.
