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. |
