Abstract
One embodiment describes a bearing damper including a housing; a damper with an annular gap and an internal spring, in which the annular gap is formed between an inner rim and an outer rim of the damper, the internal spring circumferentially bounds the annular gap, the outer rim is coupled to the housing, and the annular gap is configured to be filled with fluid used to dampen vibrations produced on a drive shaft; and an external spring coupled to the housing and to the inner rim, in which the external includes an axial stiffness engineered to externally offset axial forces exerted on the inner rim of the and a radial stiffness engineered to externally offset a first portion of radial forces exerted on the inner rim and to permit a second portion of the radial forces to propagate the vibrations from the drive shaft to the inner rim.
