INFLUENCE OF LUBRICATION ON ENDURANCE OF ROLLING CONTACTS.

Abstract

A study of elastohydrodynamic lubricant film effects in rolling ball two-ball contacts is presented. Mineral oils, ester base and polyphenyl ether lubricants with and without lubricity additives are studied. Experimental work covers development and application of contact conductivity and X-ray beam transmission measurements for film thickness and profile determination; radiotracer wear rate determination; micro-autoradiography of wear debris and of metal transfer; instrumental analysis of surface microgeometry; and rolling contact fatigue test series. A theory of asperity contact occurrences through a partial film is given. A tentative analysis of wear debris size distribution is given.
