Characterization of TEHL contacts of thermoplastic gears
Forschung im Ingenieurwesen, 2017Thermoplastic materials generally show low specific weight, low coefficients of friction, noise damping behavior and demonstrate low-cost manufacturing by injection molding. This qualifies thermoplastics for the use in lightweight gear design and more generally for an increase in resource efficiency.

Approximation Solution for TEHL of Bevel Gears in PSD ()
Journal of Applied Mathematics and Physics, 2013 To study the lubrication of the contact zone between half-shaft gears and planet gears in the power-split device (PSD), TEHL line contact of bevel gears in PSD is approximately computed based on a theory in which a bevel gear is equalized to an equivalent spur gear.

Effects of Oblique Roughness on TEHL Point Contacts
Part A: Tribomaterials; Lubricants and Additives; Elastohydrodynamic Lubrication; Hydrodynamic Lubrication and Fluid Film Bearings; Rolling Element Bearings; Engine Tribology; Machine Components Tribology; Contact Mechanics, 2006The effects of surface roughness with different orientations on thermal elastohydrodynamic lubrication (TEHL) are studied based on Eyring fluid flow model under simple sliding point contacts. The effects of the amplitude and wavelength of longitudinal roughness on TEHL point contacts are also discussed under rolling and/or sliding conditions.Copyright ©

On the TEHL Theory. Part I: Dimensionless Problem Formulation
Tribology Transactions, 1992Since the thermoelastohydrodynamic and elastohydrodynamic lubrication (TEHL and EHL) problems are predominantly heat transfer (HT) and/or fluid mechanics (FM) problems, it is proposed that the pertinent dimensionless quantities defined, in some instances tabulated, and commonly used in these branches of engineering science (HT and FM) should be used ...

Numerical analysis of TEHL line contact problem under reciprocating motion
Tribology International, 2005Abstract This paper presents a full numerical analysis to simulate the thermal elastohydrodynamic lubrication (TEHL) of steel–steel line contact problem under reciprocating motion. The equation system is solved using multigrid techniques. General tribological behaviors of TEHL under reciprocating motion are explained.

Study on TEHL flash temperature of helical gear pair considering profile modification
Industrial Lubrication and Tribology, 2022Purpose The purpose of this paper is to investigate the thermal elastohydrodynamic lubrication (TEHL) flash temperature of the helical gear pairs considering profile modification. Design/methodology/approach A flash temperature model of the helical gear pair considering the profile modification is proposed based on the TEHL and meshing theories.

Parametric Study for Design Factors on Engine Bearings by using TEHL Analysis
SAE Technical Paper Series, 2002<div class="htmlview paragraph">As the downsizing and lightening of the engine are designed, the compact and lightweight of the housing should be required. Therefore, both the engine bearing and the housing are greatly deformed under the severe condition, and a heat generation due to the friction loss increases in the bearings.

Validation of a coupled multibody and TEHL simulation by a piston/cylinder component test rig
Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2022A tribological highly stressed contact in the actuating system of axial piston machines is located between the control piston and the control chamber. This paper presents a new type of component test rig for measuring the frictional force and the gap heights between piston and cylinder.
