COMPLIANT FOIL THRUST BEARING

摘要

A compliant foil fluid thrust bearing has a single sided or two sided thrust disk (24) rotor, an integrally formed compliant foil member (40), and an underspring member (42). The non-rotating but compliant foils are located adjacetn to the thrust face of 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.
