ABSTRACT:
A resilient compliant hydrodynamic fluid film thrust bearing includes a top bearing sheet of thin metalic foil material, and a lower supporting sheet of the same or slightly heavier gauge material. The top bearing sheet is stamped to produce an annular array of truncated sector-shaped flaps attached to the array along one radially extending edge. The second section is stamped to produce an annular pattern of raised projections formed by bending the material along slits to form radially extending bumps which resiliently support the first section. The two sheets are superimposed and aligned, and are welded together along the edge by which the sector-shaped flaps are attached to the first section. The welded assemblies are then sheared from the superimposed foils and deburred.
