Surface temperature is considered as an integrated index which is a combined result of not only the load and dimensions at the contact point but also the sliding velocity, rolling velocity, surface roughness, lubrication condition and etc.. So, the surface durability of such as roller and gear will be evaluated more exactly and simply by use of the surface temperature than Hertzian stress. In this research, the surface temperatures of rollers under different rolling and sliding conditions are measured with a thermocouple. The effects of load, rolling velocity and sliding velocity on the surface temperature are clarified. An experimental formula, which expresses a linear relationship between the surface temperature and the P(0.86)Vs(1.31)Vm(-0.83) value, is presented to calculate the surface temperature. The application of this formula to the temperature measurement results of gear confirmed the formula to be effective as well to the gear tooth surface temperature calculation.
