INFLUENCE OF LUBRICATION ON ENDURANCE OF ROLLING CONTACTS.

Abstract

Lubrication studies, using radiotracer techniques and electrical conductivity measurements developed previously have been continued during this report period using a rolling four-ball test machine. Data on several lubricants under the same operating conditions are reported. A summary is presented of the process developed for preparing permanent-contact autoradiograms on metallic surfaces, and the results from autoradiograms obtained on ball sets tested in a Shell sliding four-ball machine are presented. Preliminary results are given of tests performed in a dynamic two-ball tester for the study of film thicknesses and lubrication effects on contact stresses at rolling contacts, using X-ray beam techniques. Recent results from endurance studies intended to determine the effect of lubricant films on endurance in rolling contacts are presented. (Author)
