ABSTRACT:
Conventional liquid lubrication requires a compromise between high temperature lubrication and low temperature flow. The major thrust of this invention is the preservation of the long life and reliable mechanism of elastohydrodynamic lubrication in the pursuit of elevated temperature lubrication. The mechanism of EHD lubrication is the primary source of lubrication for rolling element bearings, gears and other non-conforming contacting surfaces which must carry high loads over small areas of contact. The invention supplies the lubricant as a vapor which, upon condensation, provides an efficient replenishment of the inlet region to the elastohydrodynamic contact. For reasons of efficiency, the surfaces are encouraged to operate at elevated temperatures without cooling. Broad temperature range EHD lubrication with perfluoroalkylpolyether fluids provide full EHD lubrication up to 500.degree. C. The enhanced temperature range, small fluid quantity and the supply of lubricant in a vapor environment eliminates the need for complex lubrication and cooling hardware.
