    摘要: A sealing structure for a gas turbine blade which pivots about a pivot shaft. A split ring is located in a groove on the shaft, in which the ring can be embedded and held by a bush. When the blade is fitted, the bush abuts against a wall of the stator, slides on the pivot shaft and frees the ring, which expands and forms the seal. The invention relates to gas turbines where the stator blades have a variable setting.

    摘要: A fixing arrangement for axially fixing a blade in position on a rotor disk of a turbomachine rotor includes a relatively flexible locking wedge inserted between the root of the blade and the bottom of the axial groove in the periphery of the rotor disk in which the root is received in a radially interlocking manner, the locking wedge having a retaining hook which is received in a groove in the blade root to hold the locking wedge in position. In one embodiment the locking wedge holds a plate in position in the recesses defined by undercut projections on the upstream face of the blade root and the rotor disk to prevent axial movement the blade relative to the disk. In an alternative embodiment the downstream end of the locking wedge has a stop which engages the downstream faces of the blade root and the rotor disk to prevent axial movement of the blade in the upstream direction, and the upstream face of the blade root has a projection which overlaps and bears against an upstream face of the disk to prevent axial movement of the blade in the downstream direction.

    摘要: A sealing and retention device for the blades of a rotor which engage with axial pin settings of the rotor wherein the device includes, in a first embodiment, a flange in the shape of a circular collar which engages the rotor and a locking ring which engages the blades and the flange wherein the locking ring has a conical portion which engages a first protuberance portion of the blades such that upon centrifugal sliding of the locking ring in a radially outward direction, the locking ring is axially displaced toward the flange. The device may also include a conical crest located on the rotor and the flange may have a conical surface for engaging the conical crest of the rotor.
