Definitions

  • the invention relates to a guide vane for a vane ring of a turbomachine, a vane ring for a turbomachine and a method for mounting a vane ring.
  • Turbomachines such as aircraft engines and stationary gas turbines often have at least one compressor-side guide vane row with a plurality of guide vanes for setting optimum operating conditions.
  • the vane row forms an inner ring with a so-called vane ring.
  • the guide vanes are pivotable about their longitudinal axis.
  • a radially outer bearing of the vanes on a housing or housing part and a pivoting of the vanes can be done on outer vanes on the vanes and possibly adjoining adjustment pins that are used in associated receptacles of the housing and cooperate with a corresponding adjustment on the outer housing can.
  • the inner ring preferably has a plurality of receptacles extending in the radial direction, in each of which a guide plate of a guide vane is or can be inserted.
  • Such an (inner) stator blade serves to stabilize or a radially inner bearing of the guide vanes;
  • radial and axial refer in this document - unless otherwise stated - always on a central geometric axis of the inner ring, which is not always specially formulated for readability.
  • a vane plate may have a journal, and the receptacle may be configured to receive the trunnion together with a mating sleeve.
  • a seal carrier is preferably guided, which is provided with sealing elements or Einlaufbelegen, facing the rotor-side sealing ribs.
  • the assembly of the vanes on the inner ring is usually carried out after the outer stator blade and associated adjustment pins of the vanes are pre-assembled on the housing.
  • the inner stator blade can be used or threaded in this position in the receptacles of the inner ring, there is for the design of the inner ring various concepts:
  • the inner ring may comprise two part rings to be assembled in the axial direction and / or divided into ring segments.
  • integral inner rings are preferred in the axial direction, forming the monolithic enclosures of the individual recordings.
  • Such inner rings may be divided into two or more ring segments; it is advantageous, e.g. a division into two half rings.
  • Suitably shaped inner guide blade plates thereby enable or simplify threading of the respective guide blades into such an inner ring.
  • a vane with an inner vane plate known on the peripheral side of a chamfer is formed; this allows for the insertion of the guide plate in a circular cylindrical recording a slight inclination of the vane relative to the inner ring, which can be stretched for threading and thereby temporarily curved beyond its normal shape going out.
  • Such a chamfer also requires a relatively large cavity between an inserted guide blade plate and a wall of the receptacle; Such a cavity, in turn, may favor disadvantageous leakage, especially in unfavorable storage positions of the guide vane.
  • US 2010/232936 A1 shows an adjustable vane with an airfoil and a blade plate and a pin, both of which are provided for receiving in an inner ring.
  • the blade plate with a cover surface facing the blade leaf and a base surface facing away from the blade leaf in this case has an edge surface with a completely circumferential bevel on its base.
  • US 2013/195651 A1 describes an adjustable vane with a provided for use in a receptacle of an inner ring paddle and blade pin.
  • the blade plate has a top surface with a surface adapted to the annular space and a substantially straight running surface facing away from the flow channel.
  • At the base there is arranged a small chamfer which completely revolves with respect to the total area of the base.

  • the blade plate has on its top surface a slope which forms part of the annular space.
  • the present invention has for its object to provide a technique that allows easy mounting of a vane ring while minimizing leakage susceptibility.
  • a guide vane according to the invention for a vane ring of a turbomachine comprises an airfoil and a stator vane, with which the vane can be mounted on an inner ring (preferably pivotably).
  • the guide plate has a top surface facing the airfoil, a base surface opposite the top surface, and an edge surface connecting the top surface and the bottom surface. In a first region, the edge surface forms a chamfer of the stator blade, whereas in a second region it extends along (a portion) of a cylinder jacket surface.
  • the first region of the edge surface is bounded by a different sector of the guide plate than the second region; During one revolution of the guide disk disk along the guide blade disk edge (or the edge surface), the first and second regions are thus successively passed.
  • the guide blade plate is thus rotationally asymmetrically shaped (relative to a longitudinal axis of the guide blade).
  • the edge surface may e.g. be smooth (ie edge-free) be formed or composed of two or more surfaces that can be separated from each other by at least one edge.
  • the chamfer is preferably formed so that the guide blade plate tapers from the top surface to the base surface;
  • the base surface is preferably smaller than the top surface.
  • the top surface and edge surface abut each other at an edge formed as an ellipse or (even) as a circle.
  • the bevel caused by the chamfer allows insertion of the vane in the inclined state in an associated receptacle in the inner ring; this preferably has a size suitable for the top surface of the vane ring (so that after insertion of the vane plate between its top surface and a radially outer surface of the inner ring, preferably a gap of at most 0.5 mm, more preferably at most 0.3 mm width occurs).
  • the receptacle is preferably circular-cylindrical or formed as a section of a straight circular cylinder.
  • the guide blade plates can also be sunk into a plurality of (with respect to the inner ring) radially arranged and preassembled on the outer housing guide vanes in the respective receptacles, because can be dispensed with an exactly vertical insertion.
  • the leakage between the receptacle and the inserted guide plate is kept low because the bevel is formed only in a portion of the circumference of the guide plate (which is referred to in this document as a "first" area):
  • second "area is called
  • the second region preferably extends from the top surface to the bottom surface.
  • the edge surface of a stator blade of a guide blade according to the invention in the second region preferably comprises straight line sections which run parallel to the longitudinal axis of the guide blade, for example the edge surface may be perpendicular to the base surface in the second region.
  • This second area is set up after the onset of the Guide plate in a receptacle of an inner ring (which may have been made, for example, by means of a bore) to be adapted to its (a cylindrical surface forming) wall, which minimizes the leakage in this area.
  • An inventive vane ring comprises an inner ring and at least one guide vane according to the invention according to one of the embodiments disclosed in this document.

  • the vanes are each formed according to one of the embodiments disclosed in this document.
  • the first region of the edge surface of the respective guide plate projects further into the receptacle in the inclined position (radially) than the second region formed along a cylindrical surface;
  • the second region of the edge surface may protrude further into the receptacle than the first region.
  • the threading or insertion thus preferably comprises a chamfer in which an edge between the base surface of the guide plate and the edge surface in the first (alternatively: in the second) area is lowered into the receptacle, while (at the same time) an (eg opposite) edge between the top surface and the edge surface in the second (alternatively: in the first) area outside (or above) of the receptacle protrudes beyond the radially outer inner ring surface.
  • a particularly efficient implementation makes possible an embodiment in which all the guide vanes are inclined one after the other or simultaneously identically and / or in the same way with respect to their respective receptacle.
  • the edge surface in the first region has a circulation angle which lies in an interval of 20 ° to 170 ° (ie is at least 20 ° and at most 170 °).
  • the "angle of rotation” is the angle through which the edge surface (in relation to the inner ring to be radially arranged or arranged) longitudinal axis of the guide vane in a cross section (orthogonal to the longitudinal axis) rotates.
  • a circulation angle in such a range allows on the one hand a simple insertion of the guide plate into a corresponding receptacle, on the other hand is reduced by the upper barrier for the circulation angle disadvantageous leakage.
