ABSTRACT:
A compliant hydrodynamic fluid film thrust bearing. A circumferential row of sectors of flexible sheets are positioned to face a shaft runner for relative rotation therebetween. The flexible sheets are supported by a flexible membrane which is in turn supported by a pair of rows of corrugated foil elements. Flexible strips are sandwiched between the trailing portions of the flexible sheets and the flexible membrane to provide a tapered/land effect. The corrugated foil elements are supported by a flexible diaphragm which is in turn supported by a row of corrugated support elements which are attached thereto along circumferentially intermediate portions thereof and are aligned with the flexible strips to provide a crowning effect. The ridges of at least one of the pair of rows of corrugated foil elements have truncated apex portions. In one embodiment, ridges in corrugated foil elements of one row thereof underlie only some ridges in the other row, and furrows underlie the other ridges.
