Definitions

  • the invention relates to an axial flow machine, in particular a turbine a guide device comprising a series of adjustable guide vanes in the Flow channel, on the one hand through an inner hub and on the other through an outer guide vane carrier is limited, the guide vanes on the one hand rotatably supported in radial bearing bores of the annular guide vane carrier are and on the other hand with their head profile against the guide vane carrier, as well as with seal their foot profile against the hub, i.e. the guide vanes are supported on one side are.
  • Adjustable, in particular turbine nozzles are known to be used in turbine and turbocharger construction used around the turbine better during operation to be able to adapt the respective operating status. Because the given Characteristic of an exhaust gas turbocharger in connection with a Piston engine of high specific power makes it difficult for the to provide the desired air supply throughout the operating area.
  • the boost pressure can be reduced the air supply for a given load point within certain limits to be changed.
  • the pressure rise can then be limited according to a predetermined characteristic be that at full load the purge air pressure and thus the ignition pressure and adjust the fuel consumption of the normally designed engine.
  • Adjustable turbine nozzles usually have several around an axis rotatable guide vanes, which are articulated via levers and adjusting rings become.
  • adjustable turbine nozzles for axial and radially flow-through turbines can be distinguished.
  • radial flow through adjustable turbine nozzle can be constructed relatively easily can (see for example DE 42 18 229 C1), is the axially flow much more complex to implement, in particular the hub and Inlet housing contour spherical, d. H. at least be curved got to. This is necessary in order to ensure that the hub and Inflow housing contour to produce a uniform radial gap.
  • a generic axial flow machine, in particular flowed axially Turbine is shown in DE 42 13 709 A1.
  • the adjustable turbine nozzle offers by rotating the guide vanes there is the possibility of changing the flow cross-section in the turbine at partial load of the engine and thereby reduce the air pressure the cylinder.
  • the known, axially flowed adjustable turbine nozzle comprises within the walls delimiting the annular flow channel for one the inner hub and the other encircling the hub outer vane carrier, which is suspended in the inflow housing of the turbine.
  • the actual adjustment of the guide vane takes place via a lever linkage and preferably automatically as a function of the operating parameters such as boost pressure, Speed etc.
  • the invention has for its object an axial flow machine type mentioned in such a way that the components of the The control apparatus are both easy to operate and only minimal Allow gap flows. So both of the above requirements should be in a new axial flow machine.
  • the hub at least in the sealing area of the foot profile Guide vanes with a flexible hub contour and the one-sided Storage of the guide vanes in the guide vane carrier in the direction of Guide vane axles is also flexible, can Flow losses through gaps between the guide vane and the Inflow housing or hub contours are reduced and also Tension of the components of the adjustable diffuser caused through sealing elements and through thermal expansion of the components be avoided.
  • the inner ring for assembly with a Provide slot, so that thermal expansion can be compensated here.
  • the slot is arranged so that it lies between two guide vanes and Do not sweep through the blade contour during an adjustment process so that the losses caused by the slot are minimized can.
  • the inner ring is flanged to the hub in such a way that he in the radial direction of the inflow housing, that is in the direction of Guide vane axis is movable, but in the axial direction of the inflow housing is inserted into the hub contour with little play.
  • the inner contour of the ring Guide vane carrier, the hub, as well as the head and foot profiles of the guide vanes appropriately spherical to improve the sealing effect.
  • one generic axial flow machine is an increased friction accepted between the components, jamming of the mechanics, caused by different thermal expansions of the However, components are effectively prevented.
  • the material selection could be like this look that in the gray cast iron process from a highly heat-resistant material manufactured guide vanes are stored in a ceramic guide vane carrier and seal with their foot profiles against a cast hub. At the same time it is ensured that the gap between the guide vane and the inflow housing, or hub can be kept as low as possible, so that Flow losses can be reduced to a minimum.
  • FIG. 1 shows a partial longitudinal section through a Exhaust gas turbocharger turbine.
  • An axial flow through an annular channel 20 of an axial turbine is on the one hand by an inner hub 21 and the other by an annular Guide vane carrier 7 together with inflow housing 8 limited.
  • the guide vane carrier 7 is suspended in the inflow housing 8 in a manner not described in detail.
  • the adjustable guide vanes 30 each comprise a guide vane blade 1, one Blade pin 2 and a blade turntable 3.
  • Blade pin 2 is in one radial bearing bore of the annular guide vane carrier 7 rotatably mounted and in a known manner, for example by means of a screwed-on crown nut or the like fixed to the guide vane carrier 7.
  • Link lever 5 is rotatably attached by means of a feather key.
  • the link lever 5 is with the blade journal 2 and the guide blade carrier 7 with interposition a plate spring 4 contacted, so that the link lever 5 against the Guide blade carrier 7 supports.
  • the plate spring 4 exercises on the blade journal 2 Biasing force by which the foot profile 31, d. H.
  • the lower contour of the Guide blade 1 is pressed against the outer surface of the hub 21, So the foot profile 31 of the guide vane 30 is at the stop with the hub 21 and so seals against the contour of the hub 21.
  • the blade pin 2 is in the Bearing bore of the guide vane carrier 7 almost free of play, but still against Thermal expansion in the direction of the axis A of the guide vane 30 elastic and clamped to dampen vibrations.
  • the vane turntable 3 seals the channel 20 against the bearing bore of the guide vane carrier 7.
  • the articulation lever 5 is in a known manner via an adjusting ring 6 by no further shown actuating means movable.
  • the housing contour of the hub 21 is at least partially spherical below Inclusion of a cavity or interior 22 designed.
  • the inner ring 9 itself is provided with a slot 10, which is arranged so that it lies between two guide vanes and does not go through during the adjustment process the blade contour is painted over. To loss of mass flow through the slot To prevent 10, it is seen from the hollow or inner space 22 of the hub 21 covered with a sealing plate 11.
