On the thermal elastohydrodynamic lubrication of tilting roller pairs

Tribology International, 2013
Abstract In order to investigate thermal effect of tilting roller pairs, a numerical solution for TEHL of tilting roller pairs has been presented. Variations in the lubricating performance with tilting angle have been investigated. Comparison between thermal and isothermal solutions has been made.

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

Thermal Elastohydrodynamic Lubrication of Rider Rings

Journal of Tribology, 1984
The full thermal elastohydrodynamic analysis of the lubrication of rider rings is presented. A numerical solution of the coupled Reynolds, elasticity, energy, and Laplace’s equations for the oil film thickness, pressure, and temperature and rider rings temperatures is obtained. The temperature variation across the oil film is included.

Damping characteristics of thermal elastohydrodynamic lubricated point contacts

Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2021
The present work envisaged the development of a novel method for computing the damping coefficients of thermal elastohydrodynamic lubricated point contacts based on energy conservation. The effects of load, entrainment velocity, and slide–roll ratio were studied, and the results were compared with the ISO thermal results.

Thermal Elastohydrodynamic Lubrication of Rolling/Sliding Line Contacts

Journal of Tribology, 1992
The solution of thermal elastohydrodynamic lubrication of rolling/sliding line contacts has been obtained. The Newton-Raphson technique was used to solve the simultaneous system of Reynolds and elasticity equations. The energy equation with boundary conditions was solved by the finite-difference method.

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 ...

Traction in Thermal Elastohydrodynamic Lubrication of Rough Surfaces

Journal of Tribology, 1992
This paper studies the traction behavior of elastohydrodynamically lubricated line contacts between two rough surfaces. The study uses a thermal micro-elastohydrodynamic-lubrication (micro-EHL) model and obtains traction coefficients for a wide range of operating conditions and for film parameters as small as 1.50.

A Numerical Solution of the Thermal Elastohydrodynamic Lubrication in an Elliptical Contact

Journal of Lubrication Technology, 1982
A numerical solution for the calculation of thickness and temperature of film and traction coefficients between heavily loaded elliptical contact is developed. To start the calculation a Hertzian pressure distribution modified at the inlet and outlet regions is assumed and the surface deformations are calculated.

On the thermal elastohydrodynamic lubrication in opposite sliding circular contacts

Tribology International, 2001
Abstract Cases of elastohydrodynamic lubrication (EHL) point contacts running under opposite sliding conditions have been studied with consideration of the thermal effect for various loads and entrainment velocities. A thermal EHL solver has been developed and proven to be able to deal even with extreme cases under an infinite slide–roll ratio ...

Analysis of the thermal elastohydrodynamic lubrication of a finite line contact

Tribology International, 2002
A complete numerical solution for the thermal elastohydrodynamic lubrication (EHL) problem of a finite line contact between an infinite plane and an axially profiled cylindrical roller is obtained. The pressure profile and the film shape in the middle part of the roller are very different from those at the ends. However, the finite line contact results
