Abstract: A fluid-film journal bearing includes a resilient foil insert assembly mounted in the bore of a retaining member and having a bearing surface cooperative with the bearing surface of a rotatable journal. The retaining member has a slit extending tangential to the bore with associated means for retaining the foil and for varying the bearing clearance. The resilient foil insert comprises a continuous length of foil coiled into a plurality of layers with the innermost layer providing said bearing surface and another layer preformed into successive, undulating curves having alternating peaks and valleys.A method for fabricating the foil insert includes the use of a pair of cooperating toothed rolls to deform a portion of the foil insert into the aforesaid undulations.

Abstract: A fluid-film journal bearing wherein a resilient foil-insert assembly is disposed between a rotatable journal and a stationary retainer member. The resilient foil-insert may comprise a continuous length of foil coiled into a plurality of layers with the innermost layer providing a bearing surface and another layer preformed into a quasipolygonal configuration.

Abstract: A fluid-film thrust bearing wherein a resilient bearing insert assembly is disposed between a rotatable thrust runner and a stationary base member. The insert assembly may comprise (1) a compliant foil-like membrane having non-radial groove geometry for generating fluid pressure and (2) resilient support means mounting the membrane on the base member, the resilient support means including an array of spring elements spaced from the membrane and having a stiffness distribution matched to the pressure distribution.
