Abstract

In order to research the steady-state flow field characteristics of spherical spiral groove aerodynamic bearings, the bearing's lubrication analysis mathematical model is established. Based on CFD technology, and using the FLUENT software of fluid dynamics to analyze the 3D gas film pressure field of the spherical spiral groove aerodynamic bearings. It reveals the laws that effect of the groove width ratio, groove depth ratio, helix angle and groove number under different rotation speed on the steady-state bearing gas film pressure and the bearing capacity, and on this basis the structure of bearing parameters are optimized. The results show that the FLUENT can easily and accurately simulate the complex flow field in the gas film area, and the higher rotation speed, the more obvious gas bearing internal hydrodynamic effect. Therefore, choosing reasonable bearing structural and operating parameters contributes to improve the lubrication performance and bearing capacity.
