摘要： An air foil bearing includes a top foil, one or more orifice tubes and two or more bump foil strips disposed within a housing. The top foil is forms a substantially circular shape having one or more sets of top foil orifice holes. Each set of top foil orifice holes has at least three top foil orifice holes along a circumference of the top foil. An orifice tube is provided for each set of top foil orifice holes. The orifice tube includes a flat side having a set of tube orifice holes connected to an outer surface of the top foil. The bump foil strip is attached to the outer surface of the top foil adjacent to each side of each orifice tube. Another embodiment uses a housing with an inner surface having a curved polygonal cross-sectional shape with an odd number of curved sides.
