The failure of elastohydrodynamic lubrication
Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1984Abstract Scuffing experiments were made with circumferentially ground steel discs in a two-disc machine. The load was increased in stages until scuffing failure occurred, as indicated by a sharp increase in noise, vibration and friction.

Parched Elastohydrodynamic Lubrication
Journal of Tribology, 1985A parched subregime of elastohydrodynamic lubrication is proposed, lying between starved and mixed. Parched EHL is necessary to describe instrument ball bearing behavior, for example: long term transients in film thickness. A parched bearing has the least driving torque demand and best spin axis definition possible from any lubrication regime.

Modelling of Lubricant Degradation and Elastohydrodynamic Lubrication
2006The paper presents a new approach to modeling elastohydrodynamic contacts with degrading lubricants. Considered lubricants are diluted solutions of polymer molecules with linear structure. The problem is formulated mathematically and analyzed numerically. A parametric analysis of the problem is performed.

Nanometer Elastohydrodynamic Lubrication
1997The ultra-thin film optical interferometry technique has extended the exploration of elastohydrodynamic (EHD) lubrication to a regime where film thickness is measured in nanometers. With the gap between the lubricated surfaces corresponding to the width of just a few molecules, investigations are now being made into the validity of classical EHD theory

Elastohydrodynamic Lubrication Theory
1993Publisher Summary This chapter focuses on the load capacity of the conventional, liquid-lubricated, journal bearing benefits from the close conformity between two surfaces. Common forms of thrust bearing have films of similar proportions. This is not applicable for gear tooth engagements, cams and followers, and nor for the contact between rolling ...
