Abstract:
A method of producing a damped cylindrical shaft from a tube having between its opposite ends a bore of selected diameter, said method comprising inserting into said bore from one end of said tube a cylindrical damper having a diameter corresponding substantially to that of said bore, said damper being shorter in length than that of said bore and said damper occupying a position in said bore inward from the opposite ends of said tube; inserting into said bore at each end of said tube a plug formed of resilient, deformable material; radially contracting the opposite ends of said tube to a diameter less than that of said damper and less than that of said plugs, thereby deforming radially inwardly each of said plugs to a diametral dimension in which said plugs seal the opposite ends of said tube; and removing said plugs following the radial contraction of the opposite ends of said tube.
