Abstract

A rolling disc apparatus has been designed and built. Tractions between two crown discs lubricated with 5P4E polyphenyl ether have been measured as function of slip rate over a range of Hertz pressure (80,000-140,000 psi), rolling speeds (900-1820 ips), and temperatures (175 F - 215 F). Comparisons are made between measured tractions, Battelle data, and various analytical predictions. The MTI data agree qualitatively with Battelle measurements except that MTI data are found to be relatively insensitive to temperature whereas Battelle reports considerable temperature sensitivity. A semi-empirical mathematical model has been put forth to represent traction measurements.A computer program for analyzing interactions under partial elastohydrodynamic conditions has been written and a listing is contained in this report.
