ABSTRACT
In order to research the conical spiral groove aerodynamic bearings, the bearing's lubrication analysis mathematical model is established. The Reynolds equation of the laminar flow condition is used to calculate the 3D pressure distribution by the locally finite difference method. The influence law of the gas film pressure distribution on the bearing performance is revealed by researching the nonlinear dynamic characteristic of gas film. It reveals the laws that the effect of the bearing structural parameters on the gas film pressure distribution and the bearing capacity. The results show that the spiral groove change the gas film thickness distribution and the gas film pressure distribution and achieve good bearing dynamic pressure effect, which improve the bearing performance and the bearing stability; The structure parameters affect the gas film pressure distribution and the static characteristics. Therefore, a reasonable choice of bearing structural parameters contributes to improve the bearing's static characteristics and bearing capacity.
