Abstract

PURPOSE: A moving-blade cover which serves higher efficiency of damping vibration of turbine blades and ready connection of them.
CONSTITUTION: A moving blade cover has projection plates 6a, 6b at the front edge 4 and the rear edge 5 of the moving blades 1a, 1b reaching in contact with another moving blades 1a, 1b. With the projection plate 6a parted about a half, the upper face of the front edge 7a and the back face of the rear edge 8a are staged. Another projection plate 6b is formed to key with said projection plate 6a with a certain clearance. During running, the moving blades 1a, 1b causes relative deformation with expansion intent due to centrifugal-force-resulting untwisting. However, the oscillation can be damped by contact faces 9a, 9b of the projection plates placed approximately at the center of the full length.
