Abstract
PURPOSE: To securely fix the butt of a vane in the groove of a rotor disc and produce a high vibration-damping effect on the butt of the vane.
CONSTITUTION: Numerous grooves 2 are provided on the peripheral part of the rotor disc 1 so that the grooves extend in the axial direction. The butts of the vanes 3 are sequentially inserted into the grooves 2. A pinhole 6 is opened in the butt of each vane 3 so that the pinhole extends in the circumferential direction of the rotor disc. A pin groove 7 which has a cross-sectional area approximate to a half of that of the pinhole 6 and is concentric with therewith is provided on the pedestal part 5 of the vane 3. A pin groove 8 is provided on the peripheral part of the disc 1 in the face of the former pin groove 7. A pin 9 is inserted into the pinhole 6 and another pinhole consisting of the pin grooves 7, 8. Thus, the vane is securely fixed and the high vibration-damping effect upon the vane is produced.
