Tunable damper for a torque transferring assembly

摘要

A tunable damper (30) for a torque transferring assembly having a tubular shaft (22) including an inner surface defining an elongated cavity includes an input channeling portion (40) and an output channeling portion (42), 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 (30) further includes at least one absorber (44) 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 (44) is positioned between the input and output channeling portions (40,42) for attenuating a first predetermined range of frequencies of noise produced or transmitted by the torque transferring assembly.
