Abstract
A mounting structure for an air separator in a gas turbine includes an air separator and a rotor blade rotary disk. The air separator includes a cylindrical member with a flange at one end. The rotor blade rotary disk has on its outer face a disk recess portion forming an annular recess around the axial center of the rotor. A sealing face is formed on a contact face between a flange outer peripheral face that is provided on an outer periphery of the flange to be parallel to the axial center of the rotor and a disk recess inner peripheral face opposed to the flange outer peripheral face, that is provided on the disk recess portion and is parallel to the axial center of the rotor and formed around the axial center in an annular shape.

A mounting structure for an air separator in a gas turbine, comprising:
- an air separator that is a cylindrical member arranged so as to form a clearance communicating with an opening to an outer peripheral face of a rotor and has a flange at one end thereof;
- and
- a rotor blade rotary disk that is provided on an outer surface thereof with a disk recess portion forming an annular recess around the axial center of the rotor, wherein
- a sealing face is formed on a contact face between a flange outer peripheral face that is provided on an outer periphery of the flange and is parallel to the axial center of the rotor and a disk recess inner peripheral face opposed to the flange outer peripheral face, that is provided in the disk recess portion and that is parallel to the axial center of the rotor and formed around the axial center in an annular shape.
A mounting structure for an air separator in a gas turbine, comprising:
- an air separator that is a cylindrical member arranged so as to form a clearance communicating with an opening to an outer peripheral face of a rotor and that has a flange at one end thereof;
- and
- a rotor blade rotary disk that is provided on an outer surface thereof with a disk recess portion forming an annular recess around the axial center of the rotor, wherein
- a fitting structure between the flange and the disk recess portion is an interference fit.
A gas turbine comprising a mounting structure for an air separator, wherein the mounting structure includes
- an air separator that is a cylindrical member arranged so as to form a clearance communicating with an opening to an outer peripheral face of a rotor and has a flange at one end thereof;
- and
- a rotor blade rotary disk that is provided on an outer surface thereof with a disk recess portion forming an annular recess around the axial center of the rotor, wherein
- a sealing face is formed on a contact face between a flange outer peripheral face that is provided on an outer periphery of the flange and is parallel to the axial center of the rotor and a disk recess inner peripheral face opposed to the flange outer peripheral face, that is provided in the disk recess portion and that is parallel to the axial center of the rotor and formed around the axial center in an annular shape.
A gas turbine comprising a mounting structure for an air separator, wherein the mounting structure includes
- an air separator that is a cylindrical member arranged so as to form a clearance communicating with an opening to an outer peripheral face of a rotor and that has a flange at one end thereof;
- and
- a rotor blade rotary disk that is provided on an outer surface thereof with a disk recess portion forming an annular recess around the axial center of the rotor, wherein
- a fitting structure between the flange and the disk recess portion is an interference fit.
A mounting method of an air separator in a gas turbine that has a structure for supplying cooling air to a rotor blade rotary disk, wherein a flange provided on one end of the air separator is inserted and fitted into a disk recess portion provided on an outer face of the rotor blade rotary disk using an interference fit.
