Abstract
A vibration damping assembly for a wheel or the like that undergoes rotation is achieved by providing an annular groove in a surface of the wheel coaxial with the wheel axis. An annular metal ring formed from a channel member generally U-shaped in cross-section is positioned with one of its legs within the annular groove substantially encased therein by a vibration damping material. The remainder of the channel member extends close to areas of the wheel that are adjacent to the groove, and vibration damping material is sandwiched between the wheel and the channel member. Vibration damping material subject to shear deformation during rotation of the wheel is used, along with vibration damping material subject to deformation in tension and compression.
