ABSTRACT:
A bearing damper includes a coiled wire wrapped around projections formed on an outer race of the bearing, and supported by a casing having projections extending toward the coiled wire. Projections on the outer race are aligned with recesses on the casing, while projections on the casing are aligned with recesses in the outer race so that the coiled wire can flex between the projections that support the wire and provide a damping function. The coiled wire is formed of a plurality of strands. Flexing of the wire causes adjacent strands to rub and dissipate energy from the vibrations. The tension in the coiled wire can be adjusted in order to vary the damping capability of the bearing damper.
