Abstract

The temperature variation alters the contact state of each component during the operating process of oil-jet lubricated rolling bearings, which directly affects the dynamic performance of the bearing. However, previous studies on the dynamics of oil-jet lubricated rolling bearings do not comprehensively consider the influence of temperature factors. In addition, the impact of the temperature on the dynamic contact characteristics of the bearing is rarely investigated. To fill these gaps, this study develops a finite element model based on the mechanism of heat generation and transfer of the bearing to simulate the bearing temperature field and obtain the temperature of various components. On this basis, a dynamic model of an oil-jet lubricated axle box bearing is established to explore the influence of the radial clearance, internal temperature of the axle box and lubricating oil temperature on the contact force between the race and the rolling body by considering the influence of temperatures on the thermal deformation, lubricating oil parameters and equivalent stiffness. It was found that the influence of the temperature on bearings is primarily manifested in the elastic modulus, lubricating oil viscosity, oil film thickness, equivalent stiffness and thermal deformation. The contact force between the rolling body and the race increases significantly when the lubricating oil temperature is high, which may result in bearing pitting failure. These analysis results can provide a theoretical foundation for bearing parameter design and life research.
温度对喷油润滑滚动轴承动态接触特性的影响
在喷油润滑滚动轴承的运行过程中,温度变化会改变各部件的接触状态,从而直接影响轴承的动态性能。然而,以往对喷油润滑滚动轴承动态性能的研究并未全面考虑温度因素的影响。此外,也很少研究温度对轴承动态接触特性的影响。为了填补这些空白,本研究根据轴承的发热和传热机理建立了有限元模型,以模拟轴承温度场并获得各部件的温度。在此基础上,建立了喷油润滑轴箱轴承的动态模型,通过考虑温度对热变形、润滑油参数和等效刚度的影响,探讨了径向游隙、轴箱内部温度和润滑油温度对滚道与滚动体接触力的影响。研究发现,温度对轴承的影响主要体现在弹性模量、润滑油粘度、油膜厚度、等效刚度和热变形上。当润滑油温度较高时,滚动体与滚道之间的接触力明显增加,可能导致轴承点蚀失效。这些分析结果可为轴承参数设计和寿命研究提供理论依据。
