A variable stator blade operating device is a variable stator blade operating device that manipulates the mounting angle of a stator blade of an axial compressor. The variable stator blade operating device includes: an arm which is connected to the stator blade; a rotating ring which is connected to one end of the arm and is externally fitted to a casing of the compressor with an interval between the rotating ring and an outer wall of the casing; a drive mechanism which turns the stator blade via the arm by rotating the rotating ring; and a plurality of elastic bodies arranged in the circumferential direction around the casing, between the rotating ring and the outer wall of the casing. Each of the plurality of elastic bodies is mounted to one of the rotating ring and the outer wall of the casing and contacts the other to energize the rotating ring radially outward.

Variable stator blade operating device

To provide a variable stator vane mechanism, for an axial flow compressor, which is excellent in durability, has a simple structure, and is realized at low cost. The variable stator vane mechanism for adjusting a mounting angle of a stator vane of an axial flow compressor includes: an arm coupled to the stator vane; a rotation ring coupled to one end portion of the arm and located at an outer surface of a casing of the axial flow compressor; a driving machine configured to rotate the rotation ring to cause the stator vane to pivot via the arm; and a friction pad mounted on the casing. The rotation ring is in frictional contact with the friction pad.
