A STUDY OF THE INFLUENCE OF LUBRICANTS ON HIGH-SPEED ROLLING-CONTACT BEARING PERFORMANCE. PART V. RESEARCH ON ELASTOHYDRODYNAMIC LUBRICATION ON HIGH-SPEED ROLLING CONTACTS.

Abstract

The effects of lubricants on the performance of heavily loaded rolling-contact elements have been studied experimentally and theoretically. Measurements of the deformations of lubricated rolling elements have been made using an X-ray technique for a range of loadings, temperatures, rolling speeds, and lubricants. A qualitative agreement appears to exist between variations in deformation profiles with lubricant types and variations in existing fatigue life with lubricant type. Efforts have been made to infer film pressures from the deformation measurements. Film pressures have been measured between steel as well as quartz disks using a manganin pressure transducer. For the heavily loaded conditions, a slight pressure spike appears in the measurements of pressures between steel disks. Stresses in the rolling elements have been inferred from the pressure measurements. The magnitudes of the maximum stresses do not deviate significantly from the Hertzian stresses although the location of the maximum shearing stress is much closer to the surface. The temperature on the surface of a pair of quartz disks has been measured using an evaporated resistance thermometer type transducer. (Author)
