Thermal Elastohydrodynamic Analysis of a Worm Gear
Machines, 2023 This study explores the elastohydrodynamic lubrication (EHL) between the contacting tooth flanks of a worm gear with nonconjugate meshing action. The contact is characterized by a slender-like elliptical shape and high sliding.

Surface Roughness Effects under High Sliding EHL Conditions
Tribology Online, 2016 This paper is focused on the roughness induced effects in EHL contact under high sliding conditions when thermal effects can be expected. High sliding conditions include both the case when both surfaces are moving in the same direction and that when they
