Journal ArticleDOI
Effect of Thickener Particle Geometry and Concentration on the Grease EHL Film Thickness at Medium Speeds
TL;DR: In this paper, the authors measured the film thickness in a rolling elastohydrodynamically lubricated contact under fully flooded conditions at medium speeds and found that the relative increase in film thickness due to entrainment of the thickener was proportional to the ratio of thickener volume fraction to the size of the fibers/platelets/spheres.
Journal ArticleDOI
On a new method to determine the yield stress in lubricating grease
TL;DR: In this paper, the authors used both a controlled stress and a controlled strain rheometer to characterize lubricating grease in shear, creep, stress relaxation, and oscillatory flow, with a main focus on determining the yield stress.
Journal ArticleDOI
Mild Wear Prediction of Boundary-Lubricated Contacts
Rob Bosman,Dirk J. Schipper +1 more
TL;DR: In this paper, a wear model is introduced for the mild wear present in boundary-lubricated systems protected by additive-rich lubricants, based on the hypothesis that mild wear is mainly originating from the removal of the sacrificial layer formed by a chemical reaction between the base material and the additive packages present in the lubricant.
Journal ArticleDOI
A Model for Shear Degradation of Lithium Soap Grease at Ambient Temperature
TL;DR: In this article, the shear degradation of lithium 12-hydroxy stearate grease was measured using an in-house developed Couette aging machine, which is well defined.
