PURPOSE:To independently mount and dismount each moving blade by a method wherein the axial sliding movement of the moving blade is fastened by partially sliding a key fittingly imbedded in the recess of a rotor disc into the recess of the moving blade. CONSTITUTION:A key 7 is fittingly imbedded in advance in a recess 5 provided at the top end part 8 of a rotor disc. Next, a moving blade is inserted in a disc groove 4. A screw 14 is screwed in the threaded hole 10 of the key 7 by inserting through holes 12 and 13 provided on the pedestal 11 of the moving blade. The key 7 is pulled up by screwing the screw 14 in and fixed in order for the key 7 to engage with both the ecess 5 at the disc side and the key way 6 of the moving blade. Thus, each moving blade can be mounted to and dismounted from the rotor disc independently. |
