| Popis: |
The orifice type radial aerostatic bearing was taken as the subject. The flow field under different eccentricity and rotation speed was calculated with the three-dimension method. The influence of orifice types on characteristics of aerostatic bearings was analyzed under high-speed working conditions. For the orifice-compensated type, the influence of installation types of them on their characteristics was also discussed. The results indicate when the eccentricity is big, the orifice-compensated aerostatic bearings have a bigger main gas film stiffness and a smaller cross gas film stiffness because of the dynamic effect. The gas consumption of the orifice-compensated type is smaller than that of the orifice-restricted type with the same supply hole diameter. For the orifice-compensated type, with the increase of the number of gas supply holes, the influence of installation types decrease and can be ignored within the normal design range. |
