Experimental Equation

The surface temperature on spur gear teeth is measured by the newly developed dynamic thermocouple method. From a large number of the results an experimental equation for the surface temperature is obtained. The effect of tip relief on the surface tempera-perature rise is also studied.

Good Coincidence

The surface temperature of gear teeth is one of the important factors for evaluating the scoring resistance of a gear. In a present paper, the comparison of numerically calculated value with experimentally measured value is reported. The calculation of surface temperature was performed with the following procedure. First, the dynamic loads applied to gear teeth were calculated in consideration of the variation of different factors, for instance transmission errors of test gears and total stiffness of gear teeth. Second, under the condition that there must be no temperature discontinuity over the contact zone of sliding surfaces, the temperature distribution over the contact area was calculated. On the other hand, the measurement of surface temperature was performed using the meshing gears themselves as a dynamic thermocouple. The results of numerical solution by means of a digital computer are in fairly good coincidence with the experimental results.

Simple Stochastic Model

A simple stochastic model of interface temperature of solids in sliding contact, introduced earlier, has been extended. An experimental investigation has also been carried out, the result of which seems to lend credence to the theoretical model. The model led to the observation that, statistically, there are two temperatures at the interface, both being transients. The first is the average over the geometric contact area at all times, the temperature that is most likely to be measured by dynamic thermocouple method. The second is the time and space average over the instantaneous contacts. It is suggested that, as often as not, it is the latter which should be the reference temperature level upon which activities at the interface depend.
