The evolution of the film thickness in a grease lubricated rolling bearings is given by continuous process loss and replenishment oil track. It believed that long run, maintained bleeding from reservoirs. capabilities thus have an impact on and/or bearing life. ability to bleed changes during operation due mechanical ageing, which affects fiber structure grease. In this study lubricating consid...

In this paper, the flow dynamics of polymer greases was investigated using micro-particle image velocimetry. Polymer have a different thickener structure, compared to widely used lithium-based greases, and they well-known ability release oil. How these properties affect grease deformation its is corresponding behavior lithium complex with same consistency. Two main tests were carried out, where...

Mechanical degradation by shear is one of the mechanisms that limits life-time lubricating grease in a rolling bearing. It results change micro-structure thickener–oil system, leading to bleed and consistency. The resistance can be quantified using worker. In this article, novel approach described, where worker used measure rheological properties situ, while aging grease. energy pressure losses...

Greases with two different thickeners, namely lithium complex (LiX) and polypropylene (PP), three base oil viscosities were investigated in fretting varying displacement amplitude applied normal load. The material combinations silver-coated copper/silver-coated copper (Ag/Cu vs Ag/Cu) steel/steel investigated. Fretting maps of four the six evaluated greases constructed as a tool to better under...
