The project aims to improve the measurement of contact temperature in lubricated rolling contacts using a new thermoelectric method. Current thin-film sensors are based on thermoresistive methods, which require electrical insulation of the rolling element and thus influence heat conduction and measurement accuracy. This often leads to an overestimation of the actual contact temperature. The planned method enables a minimally invasive, more precise temperature measurement without changing the substrate or the thermal properties of the rolling element. The new method should therefore enable more reliable validation of numerical models and virtual sensors, especially under the extreme operating conditions of power-transmitting machines.
