| Abstract: | To investigate the cage stability of high-speed oil-lubricated angular contact ball bearings, a dynamic model of cages is
developed on the basis of Gupta’s and Meeks’ work. The model can simulate the cage motion under oil lubrication with all six
degrees of freedom. Particularly, the model introduces oil-film damping and hysteresis damping, and deals with the collision
contact as imperfect elastic contact. In addition, the effects of inner ring rotational speed, the ratio of pocket clearance
to guiding clearance and applied load on the cage stability are investigated by simulating the cage motion with the model.
The results can provide a theoretical basis for the design of ball bearing parameters. |
