摘要： An improved rotary machine such as centrifugal type compressor adapted to rotate under high load of the type including a plurality of impellers fixedly mounted (shrinkage-fit) on a main shaft. To effectively inhibit the rotor from vibrating due to loosened fitting of the impellers onto the main shaft the improvement consists of each of the impellers being provided with a sleeve portion which is made integral with the impeller. The sleeve portion is located at a position removed from the main part of the impeller along the axial direction of the main shaft with the position being determined in accordance with the theory of strength of materials in such a manner that displacement of the impeller in the radial direction due to centrifugal force resulting from rotation of the rotary machine has no effect on determination of the position of the sleeve portion, wherein the sleeve portion is shrink fit onto the main shaft of the impellers.

摘要： A gas turbine rotor, in which a plurality of discs having teeth of a bevel gear are juxtaposed to engage the teeth and are integrally fastened by a bolt extending through the discs, so that the discs may be cooled by feeding cooling air to the air passages of the individual discs sequentially at the running time, is provided whereby the cooling air is prevented from leaking by means having no wear. Radially outward of an air passage through hole of the faces of the adjoining discs, there are provided arms which are made lower than the dedendums of the teeth and protruded in an annular shape to confront each other; one of the arms has a tip made to have an elastically deformable thickness and a sectional shape bent inward or outward, whereas there is welded to the other arm an extension which has a tip made to have an elastically deformable thickness and a sectional shape bent inward or outward; and the end face of the tip of the one arm and the end face of the tip of the extension of the other arm are held in abutment against each other so that the two end faces may be forced, when the discs are integrated, into contact with each other to prevent leakage of cooling air.

摘要： A vibration reducer for a diaphragm coupling is capable of suppressing axial vibrations as well as torsional vibrations. A diaphragm pack 3 is mounted between a diaphragm mount flange 2 provided on an intermediate shaft 1 serving as a drive shaft and a shaft flange 4 of another shaft serving as a driven shaft. An elastic arm 5 extends through the diaphragm pack 3 and is mounted to the diaphragm mount flange 2. The elastic arm 5 is a cylindrical member, whose circumferential portion is severed by slits formed by wire-cutting. Free ends 5a of the elastic arm 5 are expanded in the radial directions by centrifugal forces caused by rotation of a shafts and come into pressure-contact with the liner member 8 formed integrally within a cylindrical portion 7 of the shaft flange 4. A part of a torque is thereby transmitted via the pressure-contact portion, and rigidity in the axial direction of the elastic arm 5 is added to that of the diaphragm pack 3 to suppress vibrations. An alternative construction has a large pressure-contact force caused by centrifugal forces realized by making use of centrifugal weights 22, a centrifugal weight holder 23, and an elongated bolt 24.

摘要： This pilot nozzle has a fuel oil supply pipe disposed at the center of a heat-shielding air layer that is provided along an axial core, and a plurality of atomized-fluid supply paths are disposed in the circumferential direction of a cylinder unit that surrounds the outside of the heat-shielding air layer. The atomized-fluid supply paths and the fuel gas supply paths are disposed alternately and uniformly. Based on this structure, it is possible to take a large thickness for the heat-shielding air layer to a maximum extent in a radial direction. Therefore, it is possible to protect the fuel oil supply pipe disposed at the center, from high temperature at the outside of the pilot nozzle.
