A STUDY OF THE INFLUENCE OF LUBRICANTS ON HIGH SPEED ROLLING-CONTACT BEARING PERFORMANCE.
Abstract
Some effects of lubricants on the performance of rolling-contact elements have been studied experimentally and theoretically. Experimental research was conducted with a rolling-disk ma chine. Sliding has been induced between the disks and the traction, sliding speed, and film thickness measured. Data are presented for polyphenyl ether (5P-4E) in the form of traction versus shear rate (sliding velocity divided by film thickness) and cover a range of pressures, temperatures, shear rates, and rolling speeds. These data depend on temperature and pressure qualitatively as would be expected. Further, the data are nonlinear at the higher shear rates and depend on the rolling speed of the disks. Thermal analyses, assuming a Newtonian lubricant model, indicate that temperature rises from frictional heating can partially explain the non linearity in the traction-shear rate data but cannot account for the variations with rolling speed. Preliminary circumferential deformation profiles have been obtained of the contact re gion using an X-ray technique. (Author)
