Abstract: For improving the running stability of tracked vehicles,the thermal property of reduction gear for electrical transmission system of tracked vehicle is studied by 1D and 3D methods. 1D software is used to calculate the outlet pressure and flow rate of each lubrication and cooling orifice of reduction gear as well as the power loss and heat transfer path of reduction gear. The lubrication flow field and temperature field are simulated to obtain the temperature distribution of reduction gear by using 3D software.The research process of thermal properties of mechanical components in electric drive system of tracked vehicle is explored. The research process shows the advantages of 1D/3D software combined simulation method for the analysis of gear thermal property. It improves the accuracy of simulation results and shortens the simulation time.

Key words: trackedvehicle, electricdrivesystem, reductiongear, thermalproperty
