| Abstract | This report describes a trial to estimate temperature rise on sliding contact surfaces of differential mechanisms for automotive drivelines by using the moving heat source theory. First, theoretical equations of contact force and relative sliding velocity of main sliding contact surfaces are shown. Next, equations for estimating the temperature rise of sliding contact surfaces and oil are derived. In the numerical examples, the temperature rise of main sliding contact surfaces is estimated to understand the tendency. The validity of this estimation theory is also verifi ed by comparing estimated and measured results of oil temperature. |
