Abstract
A surface pressure/temperature transducer has been used to measure contact zone pressure and temperature distribution between a pair of steel disks. In addition, traction/slip curves have been generated for the same conditions. Data for oils representing a broad range of lubricant types are presented. They are
(1) Synthetic paraffinic lubricant
(2) Traction fluid (synthetic hydrocarbon)
(3) Polyphenyl ether
(4) MIL-L-23699 lubricant.
The experimental conditions include two loads (0.7 and 1.1 GPa), one speed (220 inls; 5.6 m/s), and a range of slip conditions from 0–23 percent.
Very large peak temperatures, up to 200°C above ambient, were observed during the experiments. The highest peak temperatures were observed for rolling-sliding conditions with the traction fluid, but even for pure rolling conditions, temperature rises of 30°C were measured.
