Abstract

The sliding contact model and sliding dynamic model between ball and outer ring are established to investigate the ceramic bearing vibration characteristic when ball slides. The vibration characteristic and periodic rules of the system are analyzed by calculation results of the model. The heat generation model of bearing slippage is established, and the influence mechanism between temperature and oil film viscosity caused by slippage is analyzed. It can be seen from the calculation results that the contact deformation between ball and outer ring increases with the increase of radial load, and the contact deformation is smaller than the calculation results of Hertz contact model. An experimental platform for testing vibration and temperature under radial load conditions is established. The experimental results show that the vibration characteristic and temperature variation rule of bearing under large load conditions are consistent with the calculation results of the model. The average error of vibration amplitude and temperature is only 1.09% and 1.3% at 10000 r/min. It can be seen that the model established in this paper can simulate the dynamic characteristic of ceramic bearing when ball slides, and provides a certain theoretical basis for the research of rotating machinery mechanism under sliding condition.

考虑滑动因素的全陶瓷角接触球轴承动态和热耦合建模分析

建立了滚珠与外圈之间的滑动接触模型和滑动动力模型，以研究滚珠滑动时陶瓷轴承的振动特性。通过模型的计算结果分析了系统的振动特性和周期规律。建立了轴承滑动发热模型，分析了滑动引起的温度与油膜粘度之间的影响机理。从计算结果可以看出，球与外圈的接触变形随径向载荷的增加而增大，且接触变形小于赫兹接触模型的计算结果。建立了在径向载荷条件下测试振动和温度的实验平台。实验结果表明，轴承在大载荷条件下的振动特性和温度变化规律与模型计算结果一致。在 10000 r/min 时，振动振幅和温度的平均误差仅为 1.09% 和 1.3%。由此可见，本文建立的模型可以模拟陶瓷轴承在滚珠滑动时的动态特性，为滑动条件下旋转机械机构的研究提供了一定的理论依据。
