Thermal Effects in Slender EHL Contacts

open access: yesLubricants, 2022
This study deals with experimental and numerical analysis of the thermal effects of slender elastohydrodynamically lubricated (EHL) contacts under high sliding. Thereby, the entrainment direction is along the major axis of the contact ellipse.

Influence of Manufacturing Error Tolerances on Thermal EHL Behavior of Gears

open access: yesLubricants, 2022
Due to the electrification of vehicles, new demands are being imposed on gears, which translates to the tolerances of manufacturing errors. However, not many studies treat the impact of manufacturing error combinations on the lubricant behavior of gear ...

Shear Stress Analysis of EHL Oil Films Based on Thermal EHL Theory - In the Case of Elliptical Contact Condition -

open access: yesTribology Online, 2009
Under the elliptical contact conditions with an ellipticity parameter of Ke=1.4, a non-Newtonian thermal EHL analysis was carried out. The lubricating oil was assumed to behave as a Maxwell fluid.

The Transient and Thermal Effects on EHL Performance of a Helical Gear Pair

open access: yesTribology Online, 2018
A non-Newtonian numerical solution system for the transient thermo-elastohydrodynamic lubrication (TEHL) model has been proposed for a helical gear pair with the finite line contact theory. This model is used to comprehensively show the transient effect,

Influences of solid and lubricant thermal conductivity on traction in an EHL circular contact [PDF]

open access: yesTribology International, 2020
The influences of thermal conductivity of both the contacting solids and the lubricant on the traction in a rolling/sliding EHL contact have been studied numerically. For through-hardened AISI 52000 bearing steel (k was measured as 21 W/mK by Reddyhoff et al.
