| description | The high-speed angular contact ball bearing(ACBB) works under the coupling action of temperature field, electromagnetic field and other fields for a long time, so it is easy to produce local faults. In this paper, the quasi-static model of ACBB with local defects is established by considering the influence of thermal effect, high speed effect and elastohydrodynamic lubrication(EHL). Based on the quasi-static model, the friction torque model and friction heat generation model of ACBB with local defects are established, and the influence of multi-factors on the dynamic and friction characteristics of ACBB with local defects is studied. The conclusions are as follows: thermal effect and EHL have a significant influence on the dynamic characteristics of ACBB, and when there are local defects on the bearing surface, it will affect the running performance of the bearing; After considering the influence of many factors, the friction heat generation of the bearing increases, which leads to the increase of the bearing load, and finally leads to the obvious increase of the friction shear stress and friction torque in the non defective area. When the rolling element falls into the defect area, the friction shear stress decreases and is greatly affected by the axial angle of the defect. |
