Non-classical Elastohydrodynamic Lubricating Film Shape Under Large Slide-roll Ratios
Tribology Letters, 2007The authors showed in previous experiments with high viscosity polymeric lubricants that a non-classical elastohydrodynamic (EHL) film, which featured an inlet dimple, could be generated under pure sliding conditions. The phenomenon was tentatively attributed to boundary slippage.

The behaviour of elastohydrodynamic contacts at high slide-roll ratios (SRR) differs markedly from that found in rolling conjunctions and at low SRRs. Behaviour is dominated by viscosity reduction due to shear-thinning and by temperature rises in the fluid and mating surfaces.

In this study, the effect of high slide-roll ratio (2.0 ≤ S ≤ ∞) on thermal elastohydrodynamic lubrication in line contacts is explored numerically. The surface dimple produced by the heat transportation of the surface is explained. Furthermore, the deformation of the surface waviness under zero entrainment velocity is analyzed. The results show that,

A full numerical solution for the thermal EHL problem in circular contact formed by steel-glass conjunctions with slide-roll ratios larger than 2 has been carried out. An anomalous film profile, which is similar to that reported by Kaneta et al. (1996), has been obtained.

Ultra-thin film interferometry is used to measure the film thickness of an elastohydrodynamic point contact under mixed sliding and rolling conditions in the thin film regime. By maintaining a fixed entrainment speed and varying only the slide/roll ratio, the precise influence of the sliding speed on the lubricant film thickness can be determined. The
