Damper arrangement for a concentric functional part of a transmission or generator or motor, selected from a ring gear of a planetary gear, or a stator or a rotor of a large machine or device, for reducing torsionally directed vibrations, in particular structure-borne noise, with respect to the selected component, characterized in that the damper arrangement comprises a plurality of individual vibration mass damper units which are attached to the circumference of the selected concentric functional part to be damped, are connected to one another and, as a whole, form a closed ring, the inner contours of which units correspond to the curvature of the enclosed selected functional part to be damped, and which units each have at least one mass damper element and a plurality of parts for fastening, connecting and preloading, (i) each mass damper element comprising: (a) one or more vibration mass parts (3.1), each having a round or angular outer contour and a straight inner contact surface arranged obliquely with respect to the circumferential surface of the selected functional part, (b) one or more wedge-shaped bearings (3.3), which have, fully or partially, an inner contact surface curved with the radius of the selected functional part and a straight outer contact surface arranged obliquely with respect to the circumferential surface of the selected functional part, the straight, obliquely arranged outer and inner contact surfaces each forming an identical wedge angle (3.4) with the circumferential surface of the selected functional part, (c) one or more elastic layer elements or layers (3.2) which are firmly connected to and arranged between the straight, obliquely arranged, inner contact surface of the vibration mass part (3.1) and the straight, oblique, outer contact surface of the wedge-shaped bearing (3.3) such that, as a whole, they result in the geometry of a polygon which surrounds the selected functional part in side view, and (ii) the parts comprise at least one outer side part (4.1) which closes off a vibration mass damper unit on the outside and, with a greater, is curved concentrically to the radius of the selected functional part, and connecting elements (4.3) and/or clamping elements (4.4, 4.5) which allow all parts of a vibration mass damper unit to be connected and/or clamped with an axial force (4.8) such that each vibration mass damper unit and therefore also the entire damper arrangement is firmly connected to the circumferential surface of the selected functional part. (i) each mass damper element comprising: (a) one or more vibration mass parts (3.1), each having a round or angular outer contour and a straight inner contact surface arranged obliquely with respect to the circumferential surface of the selected functional part, (b) one or more wedge-shaped bearings (3.3), which have, fully or partially, an inner contact surface curved with the radius of the selected functional part and a straight outer contact surface arranged obliquely with respect to the circumferential surface of the selected functional part, the straight, obliquely arranged outer and inner contact surfaces each forming an identical wedge angle (3.4) with the circumferential surface of the selected functional part, (c) one or more elastic layer elements or layers (3.2) which are firmly connected to and arranged between the straight, obliquely arranged, inner contact surface of the vibration mass part (3.1) and the straight, oblique, outer contact surface of the wedge-shaped bearing (3.3) such that, as a whole, they result in the geometry of a polygon which surrounds the selected functional part in side view, and (a) one or more vibration mass parts (3.1), each having a round or angular outer contour and a straight inner contact surface arranged obliquely with respect to the circumferential surface of the selected functional part, (b) one or more wedge-shaped bearings (3.3), which have, fully or partially, an inner contact surface curved with the radius of the selected functional part and a straight outer contact surface arranged obliquely with respect to the circumferential surface of the selected functional part, the straight, obliquely arranged outer and inner contact surfaces each forming an identical wedge angle (3.4) with the circumferential surface of the selected functional part, (c) one or more elastic layer elements or layers (3.2) which are firmly connected to and arranged between the straight, obliquely arranged, inner contact surface of the vibration mass part (3.1) and the straight, oblique, outer contact surface of the wedge-shaped bearing (3.3) such that, as a whole, they result in the geometry of a polygon which surrounds the selected functional part in side view, and (ii) the parts comprise at least one outer side part (4.1) which closes off a vibration mass damper unit on the outside and, with a greater, is curved concentrically to the radius of the selected functional part, and connecting elements (4.3) and/or clamping elements (4.4, 4.5) which allow all parts of a vibration mass damper unit to be connected and/or clamped with an axial force (4.8) such that each vibration mass damper unit and therefore also the entire damper arrangement is firmly connected to the circumferential surface of the selected functional part.
