せたタービン動翼の翼止装置。 The wing stop plate is divided into one piece for each wing, and a dovetail groove is provided on the side of the disk for the stop plate to handle centrifugal force, and a protrusion on the wing tip surface is provided on the above stop plate in correspondence with this protrusion. For the opposite side stop plate, set screws were previously fitted into other dovetail grooves on the side of the disk, and after the blade was installed, it was fixed in the circumferential direction by the same blade. The stop plate is held down by the set screw, and the centrifugal force of the stop plate is absorbed by the L-shaped part at the bottom of the stop plate, which is hooked on the disk, thereby reducing the force applied to the set screw. Wing stop device.
