Elastohydrodynamic Lubrication Analysis of Roller Bearing Non-Normal Operation
For roller non-normal motion problems of engineering bearing, roller non-normal operation model is established. Using the method of numerical analysis, Elastohydrodynamic lubrication characteristics of roller outer ring and roller and inner ring under roller non-normal operation is studied. Results show that, film thickness decreases and pressure increases in one side of roller when small deflection of bearing roller, however, the other side of roller is the opposite. Moreover the change of the contact pressure is more noticeable which causing unbalance loading phenomenon. It is more serious between roller and in-ner ring. When roller is small deflected angle, the distribution of film thickness and stress in roller and inner is small impact-ed.
