Effect of Solid Particle on TEHL under Line Contact with Solid-Liquid Lubricant
Advanced Materials Research, 2012The two infinitely long surfaces in line contact under thermoelastohydrodynamic lubrication with solid-liquid lubricants were investigated. The time-dependent modified Reynolds equation elasticity equation and the adiabatic energy equation have been formulated and solved numerically with initial conditions using multi-grid multi-level method with full ...

On the theory of time‐dependent micro‐TEHL for a non‐Newtonian lubricant in line contacts
Lubrication Science, 1996AbstractThis 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.

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, 2014A 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

Performance of the tilting pad bearings, subjected to the harmonic vibration of the pad, is numerically analyzed. The thermoelastohydrodynamic analysis considers simultaneously the heat transfer, elastic deformation of pad’s working surface, side leakage, and the inlet pressure build-up.
