The effect of working parameters upon elastohydrodynamic film thickness under periodic load variation [PDF]

, 2020
There are a number of widely used machine components, such as rolling element bearings, gears and cams, which operate in the lubrication regime known as Elastohydrodynamics (EHD), where lubricant film thickness is governed by hydrodynamic action of ...

High Pressure Rheology of Lubricants (Part 6)

Tribology Online
In the extended Dowson-Higginson density equation in the second report, it was found that the reciprocal of the density increase ratio, 1/(ρpt/ρ0t−1), is proportional to the reciprocal of the pressure temperature, 1/PT.

Dry film lubricant is effective at extreme loads [PDF]

, 1966
Dry film lubricant protects low speed sliding surfaces under extreme loading. The lubricant in an inorganic binder is applied to substrates with sufficient hardness to prevent surface deformation in the applicable load ...

Dependence of boundary lubrication on the misfit angle between the sliding surfaces

, 2010
Using molecular dynamics based on Langevin equations with a coordinate- and velocity-dependent damping coefficient, we study the frictional properties of a thin layer of "soft" lubricant (where the interaction within the lubricant is weaker than the ...

High Pressure Rheology of Lubricants (Part 7)

Tribology Online
It is possible to calculate the oil film thickness and the pressure distribution on the Hertzian contact surface of bearings, gears, traction drives, etc. by the EHL theory by Dowson et al..

High Pressure Rheology of Lubricants (Part 2)

Tribology Online
In elastohydrodynamic lubrication (EHL) theory published in 1962, Dowson et al. derived a density pressure relational equation. Therefore, it seemed that this equation could be utilized as an estimation equation of the density term of the viscosity ...

Lubrication and Lubricants

, 2013
Lubrication is a process in which a lubricant is placed between rubbing surfaces to control friction and reduce wear. This article outlines the nature of the frictional force, the wear process, the role of surface characteristics, and the mechanisms of lubrication.

Film dynamics and lubricant depletion by droplets moving on lubricated surfaces

, 2018
Lubricated surfaces have shown promise in numerous applications where impinging foreign droplets must be removed easily; however, before they can be widely adopted, the problem of lubricant depletion, which eventually leads to decreased performance, must
