Definitions

  • the invention relates to a rotor for turbomachinery according to the Preamble of claim 1.
  • a rotor for turbomachinery is made up of several rotor disks built up, these are lined up axially and concentrically be aligned.
  • the rotor disks can carry the blading or washers and are clamped together by, generally several, tie rods and thus form a compact unit.
  • tie rods are high enough to the frictional connection between the individual rotor disks guarantee.
  • In practice which is mainly due to the Thermal expansion is affected due to the high operating temperatures is, however, not always the friction given. So shifts occur in the individual Rotor disks against each other, which lead to non-circular running System and at least to a shutdown or to their can lead to partial destruction. This has stopped the system and thus the loss of production. To the Loss of production, however, still come the system damage, which in particular lead to extremely expensive repairs, if they are repairable at all.
  • the invention tries to avoid all these disadvantages. your the task is based on a rotor for turbomachinery to indicate which is naturally trained or something can be retrofitted that an operational Misalignment [rotation or displacement] of rotor disks to each other is avoided.
  • the individual rotor disks are 1.i, which, as blade disks 1.i.1 or as Intermediate discs 1.i.2 can be formed, axially strung together and clamped together concentrically by tie rods 2.
  • the rotor disks 1.i have defined contact surfaces 1.i.1.1 or 1.i.2.1, with which they come together support and to which those caused by the tie rods 2 Attack frictional forces. These are supposed to be through the non-positive Connection a rotation or displacement of the rotor disks prevent each other in the operation of the system. However, it can Operating conditions in which these frictional forces are insufficient, a misalignment of the rotor disks 1.i against each other to prevent.
  • FIG. 5 is the additional connection of the rotor disks 1.i as a cone-shaped, preferably a double-cone-shaped Centering 4 formed.
  • This conical centering 4 is also outside the screw pitch circle 2.1 the tie rod 2 arranged.
  • the double cone preferably has a flank angle from 30 ... 60 degrees.
  • the conical centering 4 results in a form-fitting holder in the radial direction and also increases the Friction surfaces between the rotor disks 1.i and thus the Size of the transferable friction forces.
