Abstract
A rotating blade body is provided that can restrain vibrations of rotating blades effectively. The rotating blade body comprises a rotor disc, a plurality of rotating blades being assembled so as to extend from the outer circumference of the rotor disc in a radial pattern, and sealing pins extending along the direction of the rotating shaft in the gaps between the platforms of the rotating blades being adjacent in a circumferential direction. The sealing pins have a through-hole made therein, penetrating axially from one end surface to the other end surface.
Claims5
A rotating blade body comprising a rotor disc rotating with a main shaft in an integrated manner and a plurality of rotating blades being assembled so as to extend from an outer circumference of the rotor disc in a radial pattern:
- wherein a column-shaped sealing pin that extends along the direction of the shaft is provided in each gap between platforms of rotating blades being adjacent in the circumferential direction,
- wherein the sealing pin comprises a circular hole formed therethrough to penetrate in an axial direction from one end face of the sealing pin to another end face of the sealing pin;
- and
- wherein the sealing pin having the hole formed therethrough is formed by boring a tubular or cylindrical member, the sealing pin being solid except where the hole is formed and being seamless in the axial direction.
