Identification of Axial Air-Foil Bearings and Radial Air-Foil Bearings
Abstract: Air-foil bearings (AFBs) are self-acting hydrodynamic bearings, a shaft is supported by a compliant, spring-loaded foil journal lining. Once the shaft is spinning fast enough, the working fluid (usually air) pushes the foil away from the shaft so that there is no contact. The shaft and foil are divided by air's high pressure which is produced by the rotation which pulls gas into the bearing via viscosity effects. AFBs provide …
