AN ANALYSIS OF HEAT TRANSFER AND POWER LOSSES IN MECHANICAL GEARED TRANSMISSIONS

This paper presents an analysis of heat transfer capability and power losses in involute gear mechanical transmissions using, for experimental testing, electrical resistances to heat oil in the lubrication bath. The main goal was to establish a precise correlation between the thermal power released in the transmission case and the temperature difference between the oil in the bath and the ambient environment. The results indicate a very good correlation between the two sets of results, numerical and experimental, thus showing that the calculation model generates credible results and match the experimental ones.
