Effect of viscosity on rolling-element fatigue life at cryogenic temperature with fluorinated ether lubricants [PDF]
Rolling-element fatigue tests were conducted with 12.7-mm-(1/2-in.-) diameter AISI 52100 steel balls in the NASA five-ball fatigue tester, with a maximum hertz stress of 5500 mN/m2 (800 000 psi), a shaft speed of 4750 rpm, lubricant temperature of 200 K (

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 ...

The influence of heterogenous porosity on silicon nitride/steel wear in lubricated rolling contact [PDF]
, 2000 Heterogeneous porosity is detected on the surface and subsurface of hot isostatically pressed (HIPed) silicon nitride spherical rolling elements. The extent of the localised porosity accounts for an area of 6% of the rolling element surface and 4% of the

Thermal elastohydrodynamic lubrication of spur gears [PDF]
An analysis and computer program called TELSGE were developed to predict the variations of dynamic load, surface temperature, and lubricant film thickness along the contacting path during the engagement of a pair of involute spur gears.
