Molybdenum disulfide - Wikiped

Molybdenum disulfide (or moly) is an inorganic compound composed of molybdenum and sulfur. Its chemical formula is MoS 2. The compound is classified as a transition metal dichalcogenide. It is a silvery black solid that occurs as the mineral molybdenite, the principal ore for molybdenum.[6] MoS 2 is relatively unreactive. It is unaffected by ...

Heat Transfer and Thermal Elastic Deformation Analysis on the Piston/Cylinder Interface of Axial Piston Machin

In this paper, the authors present in detail the computational approach implemented to study the heat transfer and thermal elastic deformation phenomena. Simulation results for the piston/cylinder interface of an existing hydrostatic unit are discussed, considering different operating conditions and focusing on the influence of the thermal aspect.

In addition to improving the EHL modelling tools, the project will attempt to generate charts that indicate the contact conditions where the simplified EHL solutions may be used with sufficient accuracy and those where the full CFD solution may be needed. Investigation will also be made into suitable rheology models for grease as a lubricant.

Lubricants | Free Full-Text | Grease Aging Effects on Film .

Several film thickness measurements were performed with three fresh and aged lubricating greases, their base and bled oils under a wide range of operating conditions using a ball-on-disc test rig with optical interferometry. The analysis of the film thickness measurements is in agreement with the observations of several authors and adds some important aspects regarding separate film properties ...

A Theoretical and Experimental Study of EHL Lubricated .

It is known that the apparent viscosity of grease varies with service time and that grease starvation is important in EHL. However, these effects were often ignored in the research of EHL lubricated with grease. This paper deals with the thixotropy of grease and determines which value of rheological parameters can be used in numerical analysis.

Lubricants - mdpi.c

The contact between teeth requires investigation into their tribological behavior focusing on the enamel wear process against natural teeth and/or artificial teeth, allowing us to obtain useful information on the tribological behavior of restorative materials.

The Elastohydrodynamic Traction of a Grease LGLT2 .

The elastohydrodynamic (EHD) traction coefficients of a lubricating grease LGLT2 were tested at various loads and rolling speeds on a self-made test rig. Traction coefficient versus slide-to-roll ratio curves were generated. Formulae which relate traction coefficient with normal load and rolling speed are put forth.

ABSTRACTThe effect of thermal conductivity on point elastohydrodynamic lubrication (EHL) contacts was discussed with representative engineering ceramics and steel by a non-Newtonian thermal EHL analysis. Through this investigation, fundamentals of EHL characteristics of contact surfaces composed of different thermal conductivities were generally revealed and a combination of optimum ceramic ...

Mechanical degradation of lubricating grease in an EHL .

Mechanical degradation of grease in an EHL line contact between two steel rollers is studied. Three successive lubricating phases involving “fully grease covered rollers,” “slippage and grease separation,” and “formation of liquid lubricant reservoirs” are observed and characterized.
