A ROTATION PART OF ROTARY MACHINE AND METHOD FOR MANUFACTURING ROTATION PART OF ROTARY MACHINE

摘要

According to one aspect of the present invention, a rotation unit of a rotary machine comprises: a base unit of which a portion of a surface is formed to be a floor surface of a fluid passage; a plurality of blade units formed to protrude from the base unit; a plurality of shroud segment support units connected to the blade unit and formed to be extended in a direction in parallel to the floor surface of the fluid passage; a shroud segment disposed between the shroud segment support units adjacent to each other to be bonded; and a first reinforcement unit disposed in a boundary portion of the blade unit and the shroud segment support unit. Provided is the rotation unit of a rotary machine wherein a distance from a center line in a protruding direction of the blade unit to an end part of the shroud segment support unit is larger than the maximum distance from the center line in the protruding direction of the blade unit to the end part of the first reinforcement unit.
