Original Abstract

Film thickness in the starved EHL regime is often time dependent and its value is governed by lubricant supply. Rolling bearings contain multiple consequent elements which can increase the risk of starvation. Contact may starve if the replenishment mechanisms are not able to recover film thickness after element passage. One of the aspect governing the level of starvation is lubricant supply provided by previous element. This amount of oil is also used in some theoretical models as input parameter. This fact makes the experiments with ability of controlling input layer film thickness even more important. Therefore, this study presents an experimental study of relationship between lubricant film thickness at the EHL contact inlet and level of starvation. Ball on disc experimental rig with optical imaging and evaluating system was used and results of this study are compared with existing theoretical model.
