Abstract

High-speed (1761r/min~2077r/min) gear shaft is an important transmission component of wind turbines. Its thermal characteristics have an important influence on the transmission power. Therefore, in order to reduce the chance of wind turbines’ failure, study on high-speed axle’s temperature field is proposed at this paper based on transmission principle using heat transfer as well as method of finite element. This assembly model for wind turbines is firstly established in SolidWorks. Then, analysis of high-speed shaft’s temperature field is conducted with ADAMS simulation data that is input into Ansys workbench. The finite element model is established. Finally, the stress caused by temperature is superimposed to the mechanical stress. Simulation results show that with the increase of misalignment in high-speed shaft, the circumferential force on the gear shaft is also increasing. Thus, the temperature is going up by inches. Deformation also increases. Analysis of gear shaft’s temperature field has laid a foundation for the study of tooth surface bonding, gear bearing capacity, tooth modification and so on, it can also provide a basis for the future temperature prediction and fatigue life analysis.
