Abstract:
A damper assembly comprising:a shaft having an axis of rotation; a bearing about said shaft; a fixed component about said bearing; a non-rotatable, radially and orbitally movable support carrying said bearing and carried by said fixed component; a generally annular damping element interposed between said fixed component and said support, said element including a generally annular array of brush bristles extending in a generally radial plane from said fixed component with tips thereof in engagement with said support to diminish the amplitude of the shaft vibrations; a second annular damping element interposed between said fixed component and said support wherein said second element includes a generally annular array of brush bristles extending in a generally radial plane from said fixed component with tips thereof in engagement with said support to diminish the amplitude of shaft vibrations, the first-mentioned and second elements being axially spaced from one another; and said elements and said fixed component and said support defining a generally annular cavity about said support, and a conduit for supplying a pressurized medium into said cavity to increase the contact force between said bristle tips and said non-rotatable support.
