| Abstract: | With possible factors affecting the temperature rising of gearbox in operation taken into consideration as a whole, a general and practical model of the static thermal network of the gearbox is developed and more accurate simulation and expectation of temperature rising of the box are accomplished. On the basis of the results of the thermal network analysis, boundary conditions are set, finite element analysis models for the shafts and gears are further established, and temperature distrubutions of specific elements of the gearbox are concluded. |
