Original Abstract

The purpose of this paper is to reveal production mechanisms of lubrication films between non-conformal surfaces in situations, where it is not possible to designate a lubrication regime as fully flooded elastohydrodynamic contact. Under certain conditions of lubrication volume, rolling speeds, temperatures, lubrication properties or loads could lubrication film decrease under values determined by fully flooded equations. This regime is designated as starvation at it includes risk of increased wear. In this paper the methodology and the new simulator of starving contact are described. Obtained film thickness results are compared with existing numerical models.
