On the theory of time‐dependent micro‐TEHL for a non‐Newtonian lubricant in line contacts

Lubrication Science, 1996
AbstractThis paper presents a relatively complete numerical solution to time‐dependent micro‐thermoelastohydrodynamic lubrication in line contacts subjected to constant load and entraining velocity. Sinusoidal functions are employed to model the traverse roughness on contact surfaces.

A Mixed TEHL Model for the Prediction of Thermal Effect on Lubrication Performance in Spiral Bevel Gears

Tribology Transactions, 2019
Arbitrary velocity vectors on two meshing surfaces in spiral bevel gears could generate large sliding velocity, which may cause a tremendous temperature rise, especially when surface roughness is i...

A Dual Experimental/Numerical Approach for Film Thickness Analysis in TEHL Spinning Skewing Circular Contacts

Tribology Letters, 2013
Studies on the behaviour of rolling bearings show that the position as well as the loading of the rolling element at the flange roller-end contact depends on the momentum created on the roller track caused by local friction variability. This situation is characterized by a skew angle that varies within a limited range in the application influenced also

Effects of Working Conditions on TEHL Performance of a Helical Gear Pair With Non-Newtonian Fluids

Journal of Tribology, 2014
A thermal elastohydrodynamic lubrication (TEHL) finite line contact model is developed for a helical gear pair lubricated with an Eyring fluid or a power-law fluid in order to investigate the effects of the working conditions. A lubrication analysis within a meshing period shows that the differences between the Eyring and Newtonian solutions mainly lie
