摘要
考虑弹流润滑作用建立了角接触球轴承动力学分析模型,并以7004角接触球轴承为例,分析了润滑油参数对轴承动力学特性的影响。结果表明:在理想工况下,润滑油黏度对轴承加速过程影响较大;在实际工况下,润滑油初始黏度增大,轴承加速性能降低,在相同黏度下,密度增大,轴承加速性能也会降低。
Considering elastohydrodynamic lubrication,the dynamic analysis model of angular contact ball bearing is established.Taking the angular contact ball bearing 7004 as an example,the influence of lubricating oil parameters on dynamic characteristics of the bearing is analyzed.The results show that under ideal operating conditions,the viscosity of lubricating oil has a great influence on acceleration process of the bearing;under actual operating conditions,the acceleration performance of the bearing reduces with increase of initial viscosity of lubricating oil,and the acceleration performance of the bearing is also reduced with increase of density with same viscosity.
