Abstract
A compliant foil fluid thrust bearing has a single sided or two sided thrust disk rotor, an integrally formed compliant foil member, and an underspring member. The non-rotating but compliant foils are located adjacent to the thrust face or faces or the rotatable disk and are formed as arcuate segments on washer-shaped disk members. The underspring member consists of three washer-shaped disk elements that together provide variable spring stiffness in both the circumferential and radial directions.
