FIELD: machine building.SUBSTANCE: lever for bringing into rotation of turbomachine stator blade with adjustable setting angle includes the first attachment zone on driven element of lever, the second attachment zone on stator blade with adjustable setting angle and the third zone of elongated shape between the first and the second zones. At least in one section of surface at least of one of the above zones of lever there laid is laminated vibration damping element. Laminated element includes at least one layer of viscoelastic material, which is in contact with the above surface section, and one counter layer of stiff material. Other inventions refer to turbomachine and compressor of gas-turbine engine, which contains at least one above described lever for bringing into rotation of stator blade with adjustable setting angle.EFFECT: inventions allow reducing vibrations of lever for bringing stator blade into rotation.13 cl, 15 dwg |
