A system-approach to the elastohydrodynamic lubrication point-contact problem [PDF]
The classical EHL (elastohydrodynamic lubrication) point contact problem is solved using a new system-approach, similar to that introduced by Houpert and Hamrock for the line-contact problem.

Bearing elastohydrodynamic lubrication: A complex calculation made simple [PDF]
The lubricant elastohydrodynamic (EHD) film thickness formula is reduced to a simplified form whereby only the rolling-element bearing inside and outside diameters and speed (in revolutions per minute) and the lubricant type and viscosity (in centipoise)

Analysis of Elastohydrodynamic Lubrication for Steel-polymer Spur Gear Pairs
Jixie chuandongPolymer gears have the advantages of good self-lubrication and low production cost. Polymer gears are susceptible to pitting failure in transmission due to load, lubrication, etc. Metal-polymer gears' pairs have a longer service life than polymer-polymer

Elastohydrodynamic lubrication of elliptical contacts [PDF]
The determination of the minimum film thickness within contact is considered for both fully flooded and starved conditions. A fully flooded conjunction is one in which the film thickness is not significantly changed when the amount of lubricant is ...

Isothermal elastohydrodynamic lubrication of point contacts. 4: Starvation results [PDF]
The influence of lubricant starvation on minimum film thickness was investigated by moving the inlet boundary closer to the contact center. The following expression was derived for the dimensionless inlet distance at the boundary between the fully ...

Two-dimensional random surface model for asperity-contact in elastohydrodynamic lubrication [PDF]
Relations for the asperity-contact time function during elastohydrodynamic lubrication of a ball bearing are presented. The analysis is based on a two-dimensional random surface model, and actual profile traces of the bearing surfaces are used as ...
