ABSTRACT:
A drive shaft vibration dampener having an outer cylindrical housing which attaches to the end of the drive shaft. An inertia disc mounts within the housing, mounting to the housing through a spherical bearing which permits rotational and radial displacement of the inertia disc relative to the housing. A cover plate encloses the internal chamber housing the inertia disc, and the internal chamber is filled with elastomeric urethane. As the drive shaft deflects radially, the inertia disc lags behind, compressing the urethane and exerting a counteracting radial force on the housing, and the rigidly attached drive shaft.
