Abstract
A compliant, hydrodynamic fluid film bearing for supporting a rotating rotor on a stationary mount, includes a bearing sheet supported by a compliant resilient support member formed of two sheets, each having raised resilient elevations in the form of corrugations. One of these sheets is inverted with respect to the other and the corrugations on the two sheets are vertically aligned and face in opposite directions, each corrugation forming one-half of an elongated tubular spring. A metal sheet lies between the two support sheets and all three sheets, and the bearing sheet, are fastened at one end to a pair of spacer blocks. The yield strength of the support member is thus raised above the yield strength of a single support sheet while maintaining low stiffness.
