Definitions

  • the invention relates generally to turbine wheels in gas turbines and more particularly to the axial retention of vanes carried by the wheels.
  • the field of application of the invention is in particular that of industrial gas turbines and aeronautical gas turbine engines.
  • the blades are mounted on the periphery of a disk, each blade having a blade with a foot secured to a fastener axially engaged in a housing or cell opening at the periphery of the disk and extending between two opposite sides of the disc.
  • Axial retention devices for the vanes are necessary to avoid axial displacement due to vibration or thermal effects despite the pressure generated by the centrifugal force between the contacting surface portions of the blade attachments and disk housings.
  • the axial support between a blade and a corresponding tooth of the disk is positioned substantially at the extrados of the blade under the blade root.
  • the retaining flange exerts an axial lateral support on lateral faces of the teeth of the disc or of the blade attachments.
  • the retaining flange advantageously has a limited radial dimension to abut only in the lower part of the teeth of the disc or the blade attachments.
  • the axial support between the blades and the rotor and the maintenance of this axial support can be advantageously provided without consumption of the radial clearance between the rotor and an adjacent stator.
  • the retaining flange may be supported on the lateral faces of the teeth of the disc or the fasteners of the blades with prestressing.
  • the retaining flange may be mounted on the rotor being immobilized axially by a retaining ring.
  • At least one opening forming a viewing window is formed in the rotor to allow a visual control of the positioning of the retaining ring.
  • the invention further relates to a turbomachine comprising a turbine wheel according to the invention.
  • the figure 1 shows a turbine rotor 10, for example a high-pressure turbine rotor (HP) in a gas turbine engine.
  • the rotor 10 is secured to a disk 12 carrying at its periphery a plurality of blades 20.
  • the blades 20 each comprise a blade 22 which extends in the annular passage 30 for the gas flow through the turbine, which passage is delimited on the outer side by a turbine ring (not shown) adjacent to the apices of the blades.
  • Each blade 20 has its foot secured to a platform 24 carrying a fastener (or stagger) 26 by which the blade is connected to the disk 12.
  • the fastener has a profile in the form of "fir ".
  • the platforms 24 of the vanes delimit the passage 30 on the inner side.
  • the fasteners 26 are engaged axially in housings (or cells) 14 of corresponding shape distributed and opening at the periphery of the disc 10.
  • the housings 14 extend axially over the entire distance between the upstream (or front) side faces 12 a and downstream (or rear) 12 b of the disk and are separated from each other by teeth 16 of the disk.
  • the upstream and downstream terms are used herein with reference to the flow direction of the gas stream in the turbine.
  • One or more reliefs 28, for example two circumferentially aligned reliefs, may be formed on the lower face of the platform 24 of a blade 20 to bear against a stop 18 in the form of a rib.
  • a rib-shaped relief 28 formed on the lower face of the platform 24 of a blade 20 may bear against a plurality of stops 18 formed on a corresponding tooth 16 of the disk, for example two abutments 18 aligned circumferentially.
  • Fasteners 26 extend along the housing 14 and the upstream side faces 26 a and 26 b downstream of the fasteners are located substantially in the same planes as, respectively, the side faces 12 has upstream and downstream 12b at the periphery of the disc 12.
  • the trailing edge BF at the base of the blades 22 is not substantially cantilevered with respect to the fasteners 26 of the blades and an overload is not generated on the fasteners 26 on the downstream side .
  • a flange 40 On the upstream side, the axial retention of the blades is provided by a flange 40.
  • the flange 40 has teeth 42 which protrude and are supported laterally on the upstream side faces 26 are fasteners 26, without contact with the upstream side face 12a of the disk 12.
  • the flange 40 has a continuous peripheral rim 46 projecting which comes into lateral contact against the upstream side face 12a of the disk 12, to the teeth 16.
  • the mounting flange 40 can then be made with axial prestressing pressure to ensure bearing teeth 42 on the teeth 16 of the rotor.
  • axial dimensions of the fasteners 26 and teeth 16 are such that the upstream side, the fasteners 26 do not protrude out of the plane of the upstream face 12 a of the disc 12, to the teeth 16.
  • the retaining flange 40 has at its periphery an extra thickness 41 forming a cantilevered mass on the side opposite to that resting on the teeth 16 or fasteners 26. This avoids an opening of the flange at its peripheral portion with loss of support on the teeth 16 or fasteners 26 under the effect of the deformation induced by the rotation.
  • flange 40 on the rotor 10 with axial locking may be adopted, for example a bayonet mount.
  • axial retention means of the blades may be reversed, with stops formed on the upstream sides of the disc teeth cooperating with the ribs formed under the platforms of the blades and a retaining flange located on the downstream side exerting a bearing on the downstream lateral faces of the teeth or blade attachments.
