Effects of load, speed, and surface roughness on sliding EHD contact temperaturesAn infrared technique has been used to determine the effects of load, speed and surface roughness on temperature in a sliding elastohydrodynamic (EHD) point contact. Ball surface temperatures are reported for sliding speeds of 0.35 to 5.08 m/s at 0.52 to 2.03 GN/per sq m maximum pressure with surface roughness in the range 0.01 to 0.38 micron c.l.a. The relationship between asperity interaction, as measured by relocation surface profilimetry and high frequency temperature measurements, and the ratio of film thickness to surface roughness has also been studied.
