✦ Synopsis

This paper describes a detailed analysis of the flash temperature for polymer composite gears and the heat partition between gear teeth. The problem is treated as an unsteady one where the intensity distribution and velocity of heat source changes as meshing proceeds. A numerical approximation is adopted using finite different method and the results are shown to be close to those found using semi-analytical method assuming no internal hysteresis and the material properties are constant. It is shown that Blok's solution can be used to provide a quasi-steady approximation that is for mean flash temperature estimation. However, if the gear teeth start and end meshing positions are considered, Blok's solution is inaccurate and the current approach should be used.
