Original Abstract

Starvation occurs when lubricant, which is pushed away from the rolling track by rolling element, is unable to re-flow to the track. When time between overrollings or successive elements in bearing is too short, starvation becomes more severe. The effect of rolling elements stance on starvation was studied. All experiments were carried out with steel rollers, glass disc, and mineral base oil (R 834/80) with viscosity of 0.19 Pa/sec. Thickness (of the free layer) seemed to be stable for delay 8 sec. It can be assumed that necessary distance to fully replenish the track is 3.1 m for given conditions and lubricant. This is an abstract of a paper presented at the 2013 STLE Annual Meeting & Exhibition (Detroit, MI 5/5-9/2013).
