Lubriion and Fatigue Life Evaluation of High-Speed Cylindrical Roller Bearing under Misalignment

5/10/2020· This paper developed a coupled model, incorporating the quasistatic model, fatigue life model, and mixed lubriion model, to investigate the effect of misalignment angle on high-speed cylindrical roller bearings. The model is verified by comparing with the published literature results. Then, a parametric analysis is carried out.

» The SKF formula for rolling bearing life

16/2/2001· SKF life formula. A simple analytical formulation for bearing life that includes consideration of the fatigue strength of the material evolved from the rolling contact fatigue model set forth by Ioannides and Harris (1985). This was initially applied in the numerical solutions of the fatigue risk of 3-D stress fields of rolling contacts.

Axial Load Effect on Contact Fatigue Life of Cylindrical Roller Bearings …

19/4/2004· Besides primarily carrying radial load, cylindrical roller bearings with flanges or lips on both inner and outer raceways need also carry axial load in some appliions. Because of the axial load, the equivalent dynamic load of the bearing will be increased and the bearing contact fatigue life will be decreased accordingly. The axial load effect on the roller bearing fatigue …
