ABSTRACT:
A vibration damping liner for insertion in the bore of a cylindrical shaft has a cylindrical core the exterior of which is corrugated and defined by alternating grooves and upstanding flutes. The liner has an undeformed flute diameter greater than that of the bore. All of the flutes are deformed prior to insertion of the liner into the cylindrical shaft laterally of their length and in the same direction to produce a liner having a deformed flute diameter less than the undeformed flute diameter, but still greater than the diameter of the bore. As the liner is inserted in the bore, the deformed flutes may deform further radially inwardly, but once the liner is in the shaft the flutes expand into engagement with the surface of the bore. The flutes have thereon a coating of material having a coefficient of friction greater than that of the flute-forming material.
