The Research on Oil-Air Lubrication and Oil Lubrication in the Sliding Bearing
Key Engineering Materials, 2013In order to study the effect of oil-air lubrication on traditional sliding bearing, the experiments oil-air lubrication and oil lubrication have been done by using friction-abrasion testing machine. By means of measuring friction moment, the temperature rise of two different lubrication systems in the same conditions and studying the friction moment ...

Sliding on Lubricated Surfaces
1998A lubricant is used to lower the friction and reduce the wear between two sliding solid bodies. Here we consider only liquid lubricants although some solids, e.g., graphite and molybdenum disulfide, are also used as lubricants. As pointed out before, almost all surfaces are normally covered by a layer of grease, which may have a similar influence on ...

Elastohydrodynamic Lubrication of Rolling-Sliding Surfaces
SAE Technical Paper Series, 1964<div class="htmlview paragraph">The analysis of elastohydrodynamic lubrication is aimed at establishing more rational, practically applicable design and application criteria for concentrated contact, lubricated devices such as rolling bearings, gears, cams, and seals.

Temperatures at Lubricated Rolling/Sliding Contacts
Proceedings of the Institution of Mechanical Engineers, 1967A numerical method for the prediction of oil-film and metal surface temperatures is given for the case of lubricated rolling contacts with sliding. Near-Hertzian conditions occurring in gears, discs and cams are considered and the temperature distributions, viscosity variations, and the heat partition values are calculated for a range of operating ...

Sliding Friction of Lubricated Surfaces
1996I discuss the sliding motion of an elastic block on a substrate with a mono-layer of lubrication molecules. This model of boundary lubrication illustrates how the surface stress σ generated by the lubrication layer at the block-substrate interface is transmitted to the upper surface of the block.

Water Lubrication of Silicon Nitride in Sliding
Tribology Letters, 2004Several studies have shown that the coefficient of friction of self-mated silicon nitride in water decreases from an initially high value to about 0.002 after a certain run-in period. Since the worn surfaces become extremely smooth, the low friction is attributed to the initiation of hydrodynamic lubrication by a thin water film at the interface.

Lubricated Sliding Wear of Textured Surfaces
World Tribology Congress III, Volume 2, 2005In this paper, the effects of some geometric characteristics of surfaces textured by photochemical etching on their lubricated sliding behaviour were analysed. Reciprocating tests with sinusoidal velocity variation against cylindrical counterbodies were used. An estimate of the lubricant film thickness was obtained from capacitance measurements. Values

Simulation of Sliding Wear in Mixed Lubrication
Journal of Tribology, 2007Sliding wear is a significant surface failure mode in many mechanical components. The magnitude of changes in surface topography due to wear may be comparable to or larger than the original surface roughness and elastic deformation. However, wear has rarely been incorporated into the numerical models used as predictive tools in engineering practice ...

Sliding Bearing Lubricated with Ferromagnetic Fluid
A S L E Transactions, 1985To develop a bearing which is used in clean circumstances, such as in vacuum and in a clean room, an experimental thrust bearing test device was constructed. The ferromagnetic fluids selected are colloidal suspensions of ultrafine magnetite particles in a low-vapor-pressure diester and alkylnaphthalene base fluids.

Boundary lubrication of glass-rubber sliding contacts
2009Polymer brush coatings represent a promising class of coatings for friction control [1], especially in a humid environment [2]. A study on the feasibility of a specific class of polymer brush coatings [5] was done for a sliding system that involves ‘silicon skin L7350’: a silicon rubber used by FIFA for the determination of skin / surface friction in ...
