Finite Element Modeling and Analysis on Interfacial Contact Temperature of Gears Based on ANSYS
The development of modern transmission design leads to scuffing becoming more serious for transmission gears. The finite element method (FEM) is proposed that can be used as the most economical and effective designing tool for predicting the gears temperature and the distribution, determining whether the tooth scuffing or not, and analyzing the thermal stress and the deformation of gears. The thermal finite element model is developed based on ANSYS simulate the heat generation process of the friction in the involute gears engagement, which includes the bulk temperature and the transient temperature (flash temperature), analyze the heat generation on the surface of gear engagement in the different parts and the moving heat loading method. Through comparing with the result in ISO, it has showed that the finite element model that gears temperature field could calculate the bulk and the transient temperature more accurately. While the moving heat load function could not only calculate the transient temperature on the gear contact surface, but also facilitate using the method to the other types of flat or curved surface the issue of finite element moving heat loading, so it has a broader significance in the practice.
