摘要
FIELD: machine building.;SUBSTANCE: group of inventions relates to machine building. Damper comprises outer cylindrical bushing (2), inner bushing (4) made with possibility of rotation, placed into external bushing and containing internal axial channel (4b), accommodating inner friction means (5). Friction means create friction force effecting at least, on inner bushing. Rotation between inner bushing and external bushing is limited by rotation limitation system (2b, 4c, 7, 8), containing at least one axial channel (7). Axial channel is located between internal bushing and external bushing. Rotation limiting element (2b, 4c, 6) is made with possibility of displacement in appropriate channel so, that during external bushing and inner bushing rotation relative to each other, each extending element in axial channel has free movement section limited by said thrust surfaces.;EFFECT: reduced period of vibration and improved wear resistance due to free movement.;20 cl, 8 dwg
