Definitions

  • the invention relates to an axial flow machine, in particular a turbine with a number of adjustable guide vanes in the flow channel, which is bounded on the one hand by an inner hub and the other by an outer vane support, wherein the vanes are rotatably mounted on the one hand in radial bearing bores of the annular vane support and on the other hand with its head profile against the guide blade carrier, as well as with their foot profile seal against the hub, so the vanes are mounted on one side.
  • the efficiency of the turbine with an adjustable turbine nozzle in particular during operation away from the design point, be raised or lowered.
  • adjustable turbine nozzles for axially and radially traversed turbines. While the radially flowed adjustable turbine nozzle can be relatively simple (see, for example DE 42 18 229 C1 ), the axially flowed through is much more expensive to realize, since in particular the hub and Zuströmgepurtur spherical, ie at least curved must be designed. This is necessary to produce a uniform radial gap at all blade positions toward the hub and inflator housing contours.
  • a generic axial flow machine, in particular axial flow turbine shows the DE 42 13 709 A1 .
  • the adjustable turbine nozzle offers the possibility of reducing the flow area in the turbine at partial engine load, thereby increasing the air pressure in front of the cylinder.
  • the hub is designed at least in the sealing region of theticianprofiles of the vanes with a resilient hub contour and the one-sided storage of the vanes in the vane support in the direction of the vanes is also designed compliant, the flow losses through gaps between the Leitschaufel- and the Zuströmgepatuse- or hub contours be reduced and also causes tension of the components of the adjustable diaphragm be avoided by sealing elements and by thermal expansion of the components.
  • the inner ring is provided for Monday with a slot, so that a thermal expansion is compensated here as well.
  • the slot is according to the invention arranged so that it lies between two vanes and is not swept by the blade contour during an adjustment process, so that the losses caused by the slot can be minimized.
