This paper analyzes heating mechanism of all heat sources and heat quantity calculation of military track’s gear case. By using Lumped parameter method
the authors analyze the production and transfer of heat and write the procedure. The heat transfer of certain type of gear case is computed. The result shows that the method is feasible
the whole model has a high computational accuracy. The model has a good imitate accuracy
and can be used for the calculation of the other type of gear case’s heat transfer problem.
