  • Experimental study on skid damage of cylindrical

    2014-3-12 · The mechanism of skid damage to a roller bearing was examined by changing experimental conditions such as the surface topography, slip, inner ring speed, radial load and lubrication. An orthogonal experiment design was used, and the results showed that the slip affected the temperature rise the most followed by the radial load, lubrication and inner ring speed.

    2018-4-1 · This study aims to develop a damage-mechanics-based approach for subsurface-originated RCF of the outer ring of a cylindrical roller bearing. First, a two-dimensional explicit FE model is built in ABAQUS to calculate the cyclic rolling contact stresses. In the model, the roller is set to repeatedly roll across the surface of the outer ring.
