A tunable damper for a torque transferring assembly having a tubular shaft including an inner surface defining an elongated cavity includes an input channeling portion and an output channeling portion, wherein each channeling portion is formed from a first predetermined foam material having a first density and a diameter sufficient for providing a resilient bias force against the inner surface of the tubular shaft. The tunable damper further includes at least one absorber formed from a second predetermined foam material having a second density different from the first predetermined foam material and first density, respectively. The at least one absorber is positioned between the input and output channeling portions for attenuating a first predetermined range of frequencies of noise produced or transmitted by the torque transferring assembly.

Tunable damper for a torque transferring assembly

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/ft, 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.
