FIELD: machine building.SUBSTANCE: device contains a massive body making pendulum swings due to torsion oscillations. The massive body (3) is secured to a rotating body (2) by means of two support pins (5R, 5L). Two first cavities (4) are made in the outside peripheral area of the rotating body. Two second cavities (7) are made in the massive body in the points opposite to the appropriate first cavities. Guide surfaces (6R, 6L) are made on the external side of the peripheral edges of the appropriate first cavities in the radial direction relatively to the centre of rotation of the rotating body. Fastening surfaces (8R, 8L) are made on the internal side of the internal peripheral edges of the appropriate second cavities in the radial direction relatively to the centre of rotation of the rotating body. The guide and fastening surfaces are formed in the form of concave curvilinear surfaces. The distance (D) between the centres (O) of curvature of the guide surfaces is shorter than the distance (D) between the centres (O) of curvature of the fastening surfaces.EFFECT: increased efficiency of vibrations suppression.4 cl, 13 dwg |
