The temperature criterion plays a significant part in the attempt to interpret the scoring phenomenon of lubricated load-carrying machine members. Investigations were carried out to examine the correlation of the scoring bulk body temperatures, which have been measured on point and line contact machines using a modified Four-Ball and Spur Gear Tester. The simulation of the thermal model of both systems proved to be the only criterion for the correlation of the desired temperatures. A systematical investigation on the Four-Ball machine using a new temperature measuring method provided the basis to study the heating process of the sliding elements. The results show the influence of the loading and sliding velocity on both the bulk body temperature and the surface temperature.
