Lubrication Characteristics and Thermal Behavior of Non-Orthogonal Face Gear Pairs in Point Contact

Lubricants
The thermal elastohydrodynamic lubrication problem of non-orthogonal surface gear pairs under point contact conditions was studied. Firstly, a mathematical model is established through a comprehensive contact and lubrication analysis.

Mechanics of a gaseous film barrier to lubricant wetting of elastohydrodynamically lubricated conjunctions [PDF]

Two analytical models, one based on simple hydrodynamic lubrication and the other on soft elastohydrodynamic lubrication, are presented and compared to delineate the dominant physical parameters that govern the mechanics of a gaseous film between a small

On the numerical solution of the dynamically loaded hydrodynamic lubrication of the point contact problem [PDF]

The transient analysis of hydrodynamic lubrication of a point-contact is presented. A body-fitted coordinate system is introduced to transform the physical domain to a rectangular computational domain, enabling the use of the Newton-Raphson method for ...
