摘要: A journal bearing including a plurality of individual foils mounted to one of a pair of relatively rotatable members, and a plurality of undersprings which provide resilient support for the foils. The foils include a transition area defined for example by a step, adjacent the trailing edge of the preceding foil. The use of the stepped foil optimizes the geometry of the air gap profile, and thereby increases the load capacity of the journal foil bearing.
