ABSTRACT:
A lightweight damper for reducing noise and vibration in torque transferring assemblies that is easily assembled and cost efficient. The damper may be formed from a foam material having a density less than 1.4 lb/ft3, and includes an outer surface that is resiliently biased against the inner surface of a tubular shaft when installed. In a second embodiment, the damper is formed from a sheet of material that dissipates energy such as noises and vibrations through movement of the layers relative to each other. In third embodiment, the dampening sheet and foam damper are combined to provide a damper that dampens noises and vibrations across a large frequency range.
