Thin layer flow and film decay modeling for grease lubricated rolling bearings

Tribology International, 2012
A model is presented to predict lubricant supply layer changes on tracks in rolling bearings due to centrifugal forces and elastohydrodynamic contact pressure. Experimental validation is shown for centrifugal force driven free surface flow, and layer thickness (film thickness) decay in single elastohydrodynamically lubricated contacts. The model allows
