Definitions

  • the invention relates to a guide vane adjustment device for a turbomachine and a turbomachine with such a guide vane adjustment device.
  • Turbomachines known from practice have a rotor and a stator.
  • the rotor of a turbomachine comprises a shaft and a plurality of rotor blades rotating together with the shaft, the rotor blades forming at least one rotor blade ring.
  • the stator of a turbomachine comprises a housing and a plurality of stationary guide vanes, the guide vanes forming at least one guide vane ring.
  • Guide vane adjustment devices known from practice have a drive shaft to which a drive motor can be coupled and which can be driven via the drive motor.
  • the rotation of the drive shaft is transmitted via the drive motor with the aid of a control ring to all guide vanes of a guide vane ring, so that all guide vanes of a guide vane ring are adjusted or rotated indirectly with the control ring interposed starting from the drive shaft.
  • the control ring of guide vane adjustment devices known from practice can be rotated in the circumferential direction, but cannot be displaced in the axial direction and radial direction.
  • the object of the invention is to create a novel guide vane adjustment device for a turbomachine and a turbomachine with such a guide vane adjustment device.
  • the drive shaft is directly coupled to one of the guide vanes of the guide vane ring in such a way that this guide vane of the guide vane ring can be rotated directly starting from the drive shaft without the control ring being interposed.
  • the drive shaft or the guide vane which can be driven directly by the drive shaft is articulated to the control ring via a transmission lever.
  • the drive shaft is indirectly coupled to the other guide vanes of the guide vane ring, in such a way that the other guide vanes of the guide vane ring can be rotated indirectly starting from the drive shaft with the control ring interposed.
  • the guide vanes, which can be driven indirectly by the drive shaft are articulated to the control ring via further transmission levers.
  • the control ring can be displaced in the circumferential direction and in the axial direction, so that forces at coupling points between the control ring and the transmission levers articulated to the control ring run perpendicular to the transmission levers.
  • One of the guide vanes of a guide vane ring can be rotated directly by the drive shaft without the control ring being interposed.
  • the other guide vanes of the guide vane ring can be rotated indirectly starting from the drive shaft with the interposition of the control ring.
  • the guide vane which can be rotated directly or is coupled directly to the drive shaft, is articulated to the control ring via a transmission lever.
  • the indirectly rotatable or indirectly coupled to the drive shaft guide vanes of the guide vane ring are articulated to the control ring via transmission lever.
  • the control ring can be displaced in the circumferential direction and in the axial direction and can only be displaced in the radial direction. This can ultimately ensure that forces at the coupling points between the control ring and the transmission levers articulated to the control ring always run perpendicular to the transmission levers, so that bearings of the guide vanes are not loaded by parasitic force components.
  • a guide vane adjustment device can be dimensioned smaller, so that it requires less installation space.
