Title:
VARIABLE STATOR BLADE DRIVING DEVICE AND ROTARY MACHINE
Document Type and Number:
Japanese Patent JP3854562
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a variable stator blade driving device for accurately transmitting driving force transmitted from a driving mechanism to a ring, and preventing loss of the driving force.
SOLUTION: The variable stator blade driving device is equipped with a driving shaft 17 positioned near the ring 91 for rotating the variable stator blades, the driving mechanism for rotatingly driving the driving shaft 17, a first arm 11 fixed to the driving shaft 17 and protruding in the direction away from the driving axial line, and a second arm 21 positioned in the substantially tangential direction of the ring 91 and having one end rotatably connected to the ring 91 and the other end rotatably connected to the first arm 11. The variable stator blades are rotated by rotating the driving shaft 17 by the driving mechanism and by rotating the ring 91 through the first arm 11 and the second arm 21. The variable stator blade driving device is characterized in the first arm 11 having the strength for suppressing warping occurring due to driving force received by the driving shaft 17 from the second arm 21.
