Analysis of Cage Slip in Ball Bearings Considering Non-Newtonian Behavior and Temperature Rise of Lubricating Oil

The estimation of cage slips and ball slips, i.e. skidding, in ball bearings used for the main shafts of jet engines, gas turbines, and turbo machines is necessary to clarify the phenomenon of wear and smearing in the bearings. Therefore, in this study, a new method for estimating skidding has been...

Therefore, in this study, a new method for estimating skidding has been developed by taking lubricating oils to be non-Newtonian fluids, by considering oil temperature rises caused by slips occurring in the ball-to-raceway contacts, and by considering the equilibrium of forces acting between the cage and balls. These factors were not taken into consideration in Harris’ theory. To establish the adequacy of our analysis, analytical data of our study have been compared against experimental data published by Poplawski.
