    摘要: A ventilation circuit of a turbomachine turbine rotor having a turbine disk and an upstream flange disposed upstream from a combustion chamber from which it is spaced apart by a cavity. A first cooling air circuit delivers air into the cavity via main injectors and holes in the flange. A second cooling air circuit delivers air through enclosures delimited by the combustion chamber inner casing and the rotor via a discharge labyrinth, an under-injector labyrinth, and at least one labyrinth downstream from the main injectors between an annular structure and the flange. Three single-wiper labyrinths delimiting two cavities upstream from the venting cavity of the turbine disk are provided downstream from the main injectors. One of the cavities is fed with air from the second circuit upstream from the under-injector labyrinth by bore holes in the annular structure sloping tangentially in the rotation direction of the rotor.

    摘要: A fastener system is configured to fasten together at least two parts, one of which includes at least one flange that is caused to bear against a surface of the other part by a plurality of pins each presenting a collar having a non-circular outline. The collar is received in a groove formed in a bearing surface of one of the parts, and is designed to prevent the pins from turning by abutment against a wall, wherein the outline of each collar includes two substantially opposite plane surfaces that serve as mutual abutments against two adjacent collars.

    摘要: The present invention relates to an assembly composed of a rotary shaft and of a roller bearing supporting said shaft, the bearing including a ring interconnected with the shaft and forming a raceway. The assembly is characterised in that the ring is immobilised in rotation on the shaft by a coupling formed by a plurality of teeth on the shaft co-operating with lugs interconnected with the ring, the lugs being received between said teeth, and in axial direction by a snap ring transversal in the form of a ring portion. The invention applies in particular to the installation of a ring of a roller bearing on a turbine shaft.

    摘要: An apparatus for axially retaining rotor blades to an annular radially extending disk having a recess and a flange. An annular retaining ring is disposed in the recess and includes an axially extending lip and an axially outer side forming an annular bevel surface along a radially outer edge. A retaining plate having an axially extending base, a radially extending outward arm and a radially extending inward leg having an annular bevel surface along an axially inner, radially inner edge is affixed to the disk and the leg cooperates with the lip of the ring. Wherein, the bevel surfaces of the retaining plate and retaining ring are arranged outwardly opposite to one another so that the bevel surfaces are radially compressed along each other as the base slidably engages with the recess walls.

    摘要: A gas turbine stator including at least a first injector providing a passage for a main cooling air stream into a pressurized chamber. An evacuation mechanism discharges air coming from an internal labyrinth gland of a first cavity towards a lower-pressure second cavity. A second injector evacuates the air contained in the second cavity towards a main duct. The stator further includes a third injector designed to generate an overpressure close to the internal labyrinth gland in the pressurized chamber.
