Abstract
A damper system may include an inner damper having a first annular geometry and a textured surface. An outer damper may also have an annular geometry and be disposed about the inner damper. The outer damper may have a textured surface. The textured surfaces of the inner damper and outer damper may define a cavity that is configured to contain a viscous fluid.
Claims20
A damper system,comprising:
- an inner damper having a first annular geometry and a first textured surface;
- an outer damper comprising a second annular geometry disposed about the inner damper, the outer damper having a second textured surface;
- and
- a cavity at least partially defined by the first textured surface and the second textured surface, wherein the cavity is configured to contain a viscous fluid.

A bearing assembly, comprising:
- a bearing having an annular geometry and configured to rotate about an axis;
- a first damper disposed about the bearing with the first damper comprising a textured surface configured to contact a viscous fluid;
- and
- a housing disposed about the first damper, wherein the first damper is configured to dampen a deflection.
