ABSTRACT:
A vibration damper of a rotating shaft includes a floating housing attached to the shaft for radial vibratory displacement as a unit therewith, a plurality of cylindrical bores in the floating housing parallel to the axis of rotation of the shaft, and a plurality of smaller cylindrical impactors in the cylindrical bores. Each impactor is a metal sleeve having a smaller cylindrical tungsten rod therein with a damping medium around the rod. When the shaft experiences radial vibratory displacement, the sleeves impact the bores. When the sleeves impact the bores, the damping medium is squeezed from between the tungsten rods and the sleeves for vibration damping energy absorption in one mode. In addition, the tungsten rods impact the bores through the sleeves and initiate local plastic deformation of the bores the sleeves and the rods for energy absorption in another mode.
