  • Patent number: 11927100
    Abstract: The present invention relates to a method of manufacturing a labyrinth sealing device mounted between a diaphragm and a turbine rotor of a turbine in order to induce smooth rotation of the turbine rotor and prevent a leakage of gas by minimizing friction between a rotor, such as the turbine rotor, and a stator, such as the diaphragm, when the rotor rotates in the stator, wherein the labyrinth sealing device includes a ring-shaped body and a labyrinth part protruding from one surface of the ring-shaped body, the ring-shaped body is manufactured by centrifugal casting or ring mill, and the labyrinth part is manufactured by 3D printing. The method of manufacturing a labyrinth sealing can improve productivity by reducing material costs and machining costs by manufacturing the labyrinth part (or teeth) protruding from the ring-shaped body using three-dimensional printing after manufacturing the ring-shaped body by centrifugal casting or ring mill.
