ROLLING-CONTACT FATIGUE CHARACTERISTICS OF AIRCRAFT TURBINE ENGINE LUBRICANTS.
Abstract
Rolling-contact fatigue and were data were obtained for a diester, a SAE 20 paraffinic mineral oil, and a methyl chlorophenyl silicone, using a 3-ball/cone fatigue tester and 52100 air-melt tool steel test specimens. The test were conducted in dry filtered air at 10,000-rpm spindle speed, 200 F test temperature, and 700,000-psi initial maximum Hertz stress. It was found that the oil gave the shortest fatigue life and the highest wear rate, the mineral oil intermediate fatigue life and intermediate wear rate, and the silicone fluid the longest fatigue life and the lowest wear rate. The fatigue lives of the three lubricants were the same in relative order as the results of several other bench-type and full-scale tests.
