Some effects of lubricants on the performance of rollingcontact elements were studied experimentally and theoretically. Circumferential profiles of the contact region of lubricated rolling-contact disks were obtained using an X-ray technique for a range of loadings, temperatures, and rolling speed with a polyphenyl ether lubricant. A method was developed for inferring the lubricant film pressures from the measured deformations, and several profiles were analyzed to yield pressure patterns. Also, a technique was developed for measuring film pressures directly using a strip of a Manganin coating on a glass disk this disk is loaded into lubricated rolling contact with a second glass disk. The change in electrical resistance of the Manganin due to the film pressure is measured. The data recorded by these techniques appear to be fairly reproducible and consistent. Author
