    Abstract: PROBLEM TO BE SOLVED: To provide a fluid bearing excelling in aerodynamic efficiency and having a small number of components. SOLUTION: This fluid bearing is provided that includes an annular main foil having axially spaced inner and outer surfaces. Bump foils are supported circumferentially on the outer surface. Top foils are supported circumferentially on the inner surface opposite the bump foils. In one embodiment, spacers are arranged between the top foils and the main foils. The spacers can be formed by chemically etching the main foil, in one embodiment. The bump foils include first and second corrugated portions respectively providing first and second axial heights. The first axial height is set smaller than the second axial height and is arranged at a leading edge of the bump foil on the basis of the direction of airflow across the fluid bearing.

    Abstract: A thrust bearing (18) for a rotary machine (10) includes first, second and third layers (24, 26, 28). The second layer (26) includes a corrugated foil arranged between the first and third layers. The corrugated foil includes a wall having peaks (58) engaging the first layer and valleys (60) engaging the third layer. A depression (62) is arranged in the wall between first and second peaks. The depression is spaced from the first and third layers. The first layer (24) includes multiple arcuate top foils that are arranged adjacent to a thrust runner (16) of a rotatable shaft (12). A corresponding number of arcuate corrugated foils may be used to support the top foils. The third layer (28), which is provided by an annular main plate, includes multiple arcuate spacers (30) arranged circumferentially on the main plate. The spacers are generally aligned with a trailing edge (40) of the top foils. The depressions decrease the stiffness of the bump foils. The spacers direct the axial load through the thrust bearing in a desired manner.
