Abstract

PURPOSE: To improve reliability and safety at the time of the maximum centrifugal stress in such a way that bolts are inserted in the flange part between the tip area, and the labyrinth cylindrical body incorporatively formed around the outer periphery of the tip area and divided segments of runner are tightly fastened together.
CONSTITUTION: A labyrinth cylindrical body 15 is incorporatively instlled around the outer periphery of the tip area of a divisible runner 1, bolt inserting holes 12 are provided in the flange section 3 between it and the tip area of the runner, bolts 13 are inserted, and the divided segments of runner 1, 1 are tightly fastened together. This facilitates to increase tightening force on the joined faces of the flange 3 on the band side, and to inhibit the joined faces to open even at the time of the maximum centrifugal stress.
