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.

摘要： In a cooling air supply system for a rotor, cooling air is supplied from cooling air nozzles to an annular cooling air passage formed around the rotor shaft. The cooling air nozzles are formed as straight air passages having circular cross sections. The straight air passages disposed on a stationary annular nozzle member surrounding the rotor shaft. Since the nozzles are formed as straight air passages having circular cross sections, the nozzles can be manufactured accurately at low cost by machining the annular nozzle member. Further, since the freedom for the arrangement of the nozzles increases by using the straight air passages, the nozzles can be arranged in such a manner that cooling air leaving the nozzle flows into the cooling air passage around the rotor shaft without changing its flow direction. Thus, the pressure drop in the cooling air caused by changing flow direction can be largely reduced.
摘要翻译：在用于转子的冷却空气供应系统中，冷却空气从冷却空气喷嘴供给到围绕转子轴形成的环形冷却空气通道。冷却空气喷嘴形成为具有圆形横截面的直的空气通道。直的空气通道设置在围绕转子轴的静止环形喷嘴构件上。由于喷嘴形成为具有圆形横截面的直线空气通道，所以可以通过机加工环形喷嘴部件以低成本精确地制造喷嘴。此外，由于通过使用直线空气通道来设置喷嘴的自由度增加，喷嘴可以以使得离开喷嘴的冷却空气流过转子轴的冷却空气通道而不改变其流动方向的方式布置。因此，可以大幅度地减少由流动方向的变化引起的冷却空气中的压降。
