N2 - For the wet friction pair, the UMT disc-disc test was carried out to study the temperature distribution of the friction interface. The influence of relative rotational speed, applied load, and lubricating oil flow rate on the temperature change of the friction interface was analyzed. It was found that the temperature field of the contact surface can be measured by drilling temperature measuring holes of different depths in the friction lining and arranging temperature sensors. During the sliding friction process, the temperature distribution of the friction interface is not uniform. Different radial depths have different temperature values. Near the radial midpoint of the inner diameter, the temperature value is the highest, and the temperature rise rate is the largest. Next is the radial midpoint position near the outer diameter. The temperature is lowest near the edges of the inner and outer diameters of the friction linings. The temperature value of the friction interface increases with the increase of relative rotational speed and applied pressure. When the friction pair working conditions are constant, the lubricating oil flow has a certain influence on the decrease of t he friction interface temperature.
