INTEGRAL CENTERING SPRING AND BEARING SUPPORT AND METHOD OF SUPPORTING MULTIPLE DAMPED BEARINGS

摘要

An assembly includes a centering spring having an annular flange, an annular body, and a plurality of resilient beams extending from the flange to the body. The annular flange defines a passage that extends at least radially inward with respect to a centerline circumscribed by the flange from a radially outer surface of the flange to a radially inner surface of the flange. The annular body is spaced from the flange along the centerline, a radially outer surface of the body forming a first annular cavity relative to an adjacent surface configured to be a first fluid damper. A deflection of the body relative to the flange is restrained by a restoring force produced by the plurality of resilient beams and the first fluid damper. A method includes providing the aforementioned assembly and passing a damping fluid through the passage of the flange.

1. An assembly comprising:
a centering spring comprising:
an annular flange defining a passage that extends at least radially inward with respect to a centerline circumscribed by the flange;an annular body spaced from the flange along the centerline, wherein a radially outer surface of the body is spaced from an adjacent surface to form a first annular cavity operative as a first fluid damper; anda resilient member extending from the flange to the body, wherein a deflection of the body relative to the flange is restrained by a restoring force of the resilient member and the first fluid damper;wherein the passage extends from a radially outer surface of the flange to a radially inner surface of the flange.
