To study the lubrication performance and structural strength of transmission shafting of the intermediate gearbox of a certain helicopter, applying theories of tribology and heat transfer, thermal-structural coupling simulations of the entire transmission shafting, which mainly consists of a spiral bevel gear pair, two bearings, are performed based on the software platform of ANSYS Workbench. Both steady-state temperature field and stress field are obtained, and influences of rotational speed, torque on the thermal-structural coupling effect are discussed.
