The Investigation on Lubrication State of Gears

Tribology Transactions, 1994
A computer program for analyzing the lubrication state of gears was developed, and the lubrication states of two lubricants on two test rigs were investigated. The calculation and tests correlated well. Finally, satisfactory results were achieved when the program was used on an industrial field. Presented at the 48th Annual Meeting in Calgary, Alberta,

Research on thin film lubrication: state of the art

Tribology International, 2005
Thin film lubrication (TFL) has been well studied as a new lubrication regime since 1990s. TFL is a transition lubrication regime between elastohydrodynamic lubrication (EHL) and boundary lubrication (BL), which has specific lubrication features. Present paper summarizes the advancements of researches on TFL, which involves the origin of the TFL ...
