TL;DR: This work reviews gear lubrication papers with focus on gear efficiency, contact fatigue and dynamics, and compile and categorize key investigations in an expansive field with substantial recent research.

TL;DR: In this article, the residual stress and surface topography obtained by various shot peening treatments were experimentally and theoretically examined, and it was found that the ratio between the layer thickness of compressive stress and the critical depth of maximum stress generally lies in the regime of 3.6-4.3 after shot-peening.

TL;DR: In this article, the effect of shot peening coverage on residual stress, surface roughness, microhardness and microstructure of rollers is investigated, and it is shown that the shot-peening leads to a slight increase of surface and near-surface hardness from 690 HV to 740 HV, and an appreciably increasing of the subsurface maximum compressive residual stress.

TL;DR: In this article, a thermal starved elastohydrodynamic lubrication (EHL) model is proposed to study effect of starved lubrication on the contact performance of a spur gear pair.

TL;DR: In this article, a multiple-shot model was used to estimate the evolution of shot peening coverage and the influences of coverage on residual stress, plastic strain and surface topography, and the predicted results reveal that as the shot-peening coverage increases from 100% to 400% under the given processing condition, the maximum residual stress and plastic strain will increase gradually.
