One embodiment includes a plurality of equally spaced top foils (314) and corrugated springs (316) with one or more shims (318) underneath the trailing edge of each corrugated spring. The corrugated spring (316) forms an underspring for the top foil (314). Another embodiment incorporates at the trailing edge of the corrugated spring. The shim (318) under the trailing edge of the corrugated spring results in increased load capacity and stability and a decrease in lift- off speed of the rotating thrust disk (305). The shims (318) located at the outer radii of the corrugated springs result in increased bearing stiffness at the outer region of the compliant foil thrust bearing where the highest pressure occurs. |
