Analysis of the oil distribution in starved elliptical E.H.D. contacts

DOI: 10.1016/s0167-8922(03)80181-5


Publisher Summary This chapter describes some of the issues raised in the elliptical contact analysis to provide additional insight into the local character of starvation in elliptical contacts, to quantify the amount of oil lost from the track in the inlet and outlet regions, and to analyze the local oil film redistribution in the inlet region. The starved regime is characterized by a lack of lubricant in the inlet of the contact. An incomplete oil film profile is imposed in the inlet. Experimentally, this oil profile corresponds to the oil profile found in the outlet of the previous pass. From a numerical point of view, it constitutes a boundary condition and the meniscus position is treated as a free boundary problem. The chapter describes ejection in inlet and outlet and oil profile smoothing.
