Some important aspects of thermal elastohydrodynamic lubrication

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2010
Thermal effect in elastohydrodynamic lubrication (EHL) has been the subject of study for the last four decades; however, some important aspects related to the physical behaviour of the lubricant in response to pressure, temperature, and shear rate remain largely neglected. This paper presents a brief review of the thermal EHL literature and sheds light

A Thermal Model for Elastohydrodynamic Lubrication of Rough Surfaces

Tribology Transactions, 1992
This paper reports on the development of a thermal model that can be 4us1ed to analyze transient elastohydrodynamic lubrication (EHL) of rough surfaces. The thermal domain is composed of three sub-domains, including the film region and the two bounding solids with the thermal boundaries placed inside the solids at which the temperature variation is ...

Modeling the effects of solid thermal expansion and thermal stress on elastohydrodynamic lubrication

Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2022
Temperature has a significant effect on the performance of elastohydrodynamic lubrication (EHL), and this topic has been extensively covered in many studies. These studies are focused on how temperature affects lubrication performance, without considering the effect of temperature on the deformation and the subsurface stress of the contact bodies ...

Thermal Elastohydrodynamic Lubrication of Rolling/Sliding Contacts

Journal of Tribology, 1990
A complete numerical solution of thermal compressible elastohydrodynamic lubrication of rolling/sliding contacts has been obtained. The Newton-Raphson technique is used to solve the simultaneous system of Reynolds and elasticity equations. The control volume finite element modeling was employed to solve the energy equation and its boundary conditions ...

Thermal Elastohydrodynamic Lubrication Analysis for Point Contact Transmission

Volume 4: Design and Manufacturing, 2009
To investigate the thermal EHL (elastohydrodynamic lubrication) in point contact transmission, a model considering the two-dimensional surface velocity of tooth face and the running-in is proposed. The numerical solutions for pressure, temperature and film thickness distribution in the contact zone are obtained by solving equations including the ...
