Title:
LUBRICATION SYSTEM AND PROCESS FOR HIGH SPEED ANTIFRICTION BEARINGS
Document Type and Number:
WIPO Patent Application WO2001063132
Kind Code:
A3
Abstract:
A high speed antifriction bearing (A, E, J) receives minute quantities of high performance grease or oil at selected intervals from an electrically controlled injector (D, H, I) having a nozzle (84, 184) that is directed at the rolling elements (6, 154) of the bearing. By minimizing the lubricant in the bearing, the lubricant does not accumulate in quantities that render it susceptible to working. The high performance lubricant produces a boundary layer film between contacting critical surfaces (14, 20, 30, 34, 36, 154, 156, 158) within the bearing. That film is so thin that it has little capacity to churn or work and produce heat. The injector may be the type used for electronic injection of diesel fuel into the cylinders of diesel engines.
