Shaft sealing apparatus and rotating machine equipped therewith
A shaft sealing apparatus is installed in an annular space between a rotor and a stator in a rotating machine and divides the annular space into a low-pressure side region and a high-pressure side region in an axial direction of the rotor. The shaft sealing apparatus includes a seal body formed by stacking a plurality of thin seal pieces, which extend from the stator toward a radial inner side of the rotor, in a circumferential direction of the rotor, and lateral plates having a surface facing the axial direction and curved and extending in a circumferential direction of the annular space. The seal body is welded to the surfaces of the lateral plates which face the axial direction so that the seal body follows a curved shape of the lateral plates.
