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.

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.

An Investigation into Grease Behavior in Thermal EHL Circular Contac

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The behaviors of two lithium lubricating greases were inves-tigated under EHL circular contact through measurements of traction coefficients on a self-made rig in which the contact was continuously fed with fresh grease. The average values of Erying shear stress and shear modulus of the two lithium greases were ...

The Efficiency of a Simple Spur Gearbox — Thermally .

However, there are currently no efficiency models that consider a full spur gearbox, including the all-important thermal coupling, taking into account the mesh and bulk temperature rise of all drivetrain components or that of the oil surrounding them as well as all sources of energy loss including bearings, seals, churning, and EHL traction.

The Elastohydrodynamic Traction of a Grease LGL

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.

Finally, the elastohydrodynamic lubrication (EHL) model of axle box bearings is established considering thermal and scale effects. The results show that the central film thickness under thermal EHL was decreased by 13.61% compared with that under isothermal EHL.

The Development of a Lubricant Traction Measurement Syst

Abstract. A ball-disc traction test rig is improved through the development of a lubricant traction measurement system, consisting of a resonance force sensitive quartz sensor, a circuit of the sensor and a rigid bracket jointed by a frictionless hinge.
