The present invention concerns a damping apparatus for the damping of vibrations in tool holders, machine elements and work pieces in machine tools and in other objects that are exposed to unwanted vibrations. The damping apparatus is adapted to be provided in or on the object and includes a substantially cylindrically shaped damping body (1) with a boring (6) going there through and a through the boring extending longitudinal central body (3) that is rigidly connectable to the object that is to be damped. The damping body (1) is connected to the longitudinal central body through elastic elements (2). The connection is made such that the elastic elements (2) are substantially exposed to shear forces during damping.

La présente invention concerne un appareil amortisseur servant à amortir des vibrations dans les porte-outils, dans des éléments de machines et dans des pièces à usiner dans des machines-outils, ainsi que dans d'autres objets qui sont exposés à des vibrations indésirables. L'appareil amortisseur est conçu pour être disposé à l'intérieur de l'objet ou sur lui. Il comporte un corps amortisseur (1) de forme sensiblement cylindrique traversé d'un alésage (6) dans lequel passe un corps central longitudinal (3) pouvant se relier de façon rigide à l'objet devant bénéficier de l'amortissement. Le corps amortisseur (1) est relié par des éléments élastiques (2) au corps central longitudinal. La liaison est faite de façon que les éléments élastiques (2) soient sensiblement exposés à des forces de cisaillement pendant l'amortissement.
