Definitions

  • the disclosure relates to the field of turbomachines to which exhaust gases of internal combustion engines are admitted.
  • a guide device is disclosed for generating a preswirl in the intake region of a compressor and an exhaust gas turbocharger having such a preswirl guide device.
  • variable turbine and/or compressor geometry offers a widespread possibility in this respect.
  • the guide vanes of the distributor upstream of the turbine wheel are oriented more or less at a steep angle to the flow in accordance with the power requirement of the turbine.
  • the guide vanes in the diffuser downstream of the compressor wheel are oriented more or less at a steep angle to the flow.
  • preswirl guide devices which in the intake region of the compressor generate a certain preswirl in the drawn-in air or possibly in the drawn-in air/fuel mixture, in a more or less pronounced manner depending on the operating point, in the direction of rotation of the compressor wheel or in the opposite direction.
  • a preswirl guide device which can function reliably for a long operating period, is simple to fit and has adjustable guide vanes.
  • An exemplary preswirl guide device for generating a preswirl in the intake region of a compressor comprises a plurality of guide vanes which are pivotable about a respective vane shank connected to the guide vane, the vane shanks and therefore the axes of rotation of the guide vanes being oriented essentially perpendicularly and radially relative to the shaft axis of the compressor.
  • the exemplary preswirl guide device can comprise an adjusting ring, arranged coaxially to the shaft axis of the compressor and pivotable about this axis, and an adjusting lever for transmitting torque from the adjusting ring to the vane shank of each guide vane.
  • the vane shank and the adjusting lever of each guide vane can be of one-piece design.
  • the number of joints can be reduced, which can have a positive effect on the material wear.
  • the number of components to be fitted can be reduced. This simplifies the fitting and possible service work on the guide device.
  • the casing of the exemplary preswirl guide device in which casing the guide vanes can be rotatably mounted, comprises at least two parts joined together in the region of the bearings of the guide vanes.
  • the bearings can be protected with inserted bearing sleeves.
  • This axial mounting of the guide vanes can be effected via projections on the vane shanks and on the casing surrounding the vane shanks. These projections extend in the radial direction with respect to the axis of rotation of the guide vane. The projections engage one inside the other for the axial mounting of the guide vane.
  • grooves may also be incorporated in the casing and/or in the vane shanks, said grooves interacting with corresponding projections for axially securing the guide vane. If grooves are incorporated in both the casing and the vane shanks, the axial mounting may be effected with special bearing rings which are arranged in the grooves. The grooves and the projections may also extend only partly around the respective vane shank.
  • FIG. 1 shows a section through a first exemplary embodiment of a preswirl guide device having a central body held by means of a retaining rib
  • FIG. 2 shows an isometric detailed view of the exemplary preswirl guide device according to FIG. 1 ,

  • FIG. 8 shows a section through an exemplary preswirl guide device having a central body held by the guide vanes
  • FIG. 9 shows a detail with an alternative variant of the second exemplary embodiment, according to FIG. 3 , of the preswirl guide device.
  • FIG. 1 shows a section through a guide device in the intake region of a compressor.
  • such compressors are used in exhaust gas turbochargers for increasing the output of internal combustion engines.
  • the arrows in the figure indicate the flow path of the medium to be compressed, which can be air or possibly an air/fuel mixture for the combustion process in the internal combustion engine.
  • guide devices can be used in any type of compressor, for example in industrial compressors driven by electric motors.
  • the guide device comprises a plurality of guide vanes 10 arranged so as to be oriented in the radial direction with respect to the compressor axis.
  • Each of the guide vanes comprises, in addition to the vane profile 11 projecting into the flow duct, a vane shank 12 with which the vane profile can be rotatably mounted in a casing.
  • the vane profile can be rotated about the axis of the vane shank via an adjusting lever 13 .
  • An adjusting ring 30 which is arranged concentrically to the axis of the compressor is provided in order to drive the adjusting lever and thus adjust the vane profile. All the vanes can be adjusted simultaneously about the respective axes of their vane shanks by rotating the adjusting ring 30 .
  • the torque transmission from the adjusting ring 30 to the vane shank 12 can be effected via a ball head 14 arranged on the free end of the adjusting lever 13 .
  • the ball head 14 can be guided in a groove 31 of the adjusting ring, said groove 31 having two walls running parallel to one another. In the groove, the ball head can have the translatory and rotary freedom of movement necessary for realizing the torque transmission.
  • the surface acting on the ball head of the adjusting lever for transmitting the torque from the adjusting ring to the vane shank of each guide vane can be designed like a ball socket.
  • the ball socket is formed at least partly from a sliding shoe 20 arranged to be displaceable in a translatory manner. If the adjusting ring 30 is rotated for adjusting the guide vanes, the sliding shoe 20 is displaced by the ball head 14 in the groove 31 in the plane of the groove walls. If the adjusting ring is rotated, the position of the adjusting lever changes relative to the adjusting ring.
  • the adjusting lever rotates relative to the adjusting ring.
  • the translatory displacement of the center of rotation of the ball head can be made possible by the sliding shoe sliding along the groove walls, whereas for the rotation the ball head can rotate in any desired direction in the ball socket formed by the sliding shoe.
  • the sliding shoe may also be of two-piece design by a ball socket half having a flat, slidable rear side being arranged on each side of the groove in the adjusting ring.
  • the torque transmission from the adjusting ring 30 to the vane shank 12 can be effected via a cylindrical pin 15 arranged on the free end of the adjusting lever 13 .
  • the pin engages in a hole of a cylindrical sliding element 21 mounted in the adjusting ring 30 likewise in a hole 32 .
  • the sliding cylinder 21 can be rotated about its own axis in the hole 32 and can be displaced along its own axis.
  • the hole in the sliding cylinder this hole being provided for accommodating the pin 15 , can be perpendicular to the axis of the sliding cylinder.
  • the pin can be rotated about its own axis in this hole and can be displaced along its own axis.
  • the pin 15 may be fixed in the sliding cylinder 21 and may be mounted instead in a sliding manner in a corresponding hole in the free end of the adjusting lever 13 of the guide vane.
  • the vane profile, the vane shank and the adjusting lever can be cast as one piece and then the ball head or the pin driven with an interference fit into an opening, provided for this purpose, in the adjusting lever or else loosely inserted and welded or cast in place.
  • the casing can be split in the region of the bearing points of the guide vanes.
  • At least two casing parts 41 and 42 which can be joined together in the axial direction with respect to the compressor axis can be provided. In the region of the bearing point of each guide vane, the two casing parts jointly form the aperture 45 .
  • the two casing parts 41 and 42 can be held together, for example, with connecting elements in holes 46 provided for this purpose or via other subsequently installed casing parts.
  • the vane shank can thus be secured in the axial direction in a simple manner on radially projecting casing edges 49 , instead of with an additional bearing bush or with external bearing points.
  • These casing projections 49 may be provided on both sides or on one casing part in each case at the axial ends of the bearing point of the vane shank.
  • a groove extending over at least part of the circumference in the aperture between the two casing parts 41 and 42 can accommodate a projection 17 likewise extending over at least part of the circumference of the vane shank.
  • the groove may also be incorporated in the vane shank in another variant and the casing parts may be provided with a corresponding projection.
  • a groove can be incorporated in one casing part, whereas the other casing part has a projection and accordingly the vane shank is provided with a respective projection and a respective groove.
  • the rotatability of the guide vanes can also be limited in a simple manner by means of a groove that does not extend over the full circumference and a projection that extends over an even smaller part of the circumference.
  • grooves can be incorporated in both the vane shank and the casing surrounding it.
  • a bearing ring arranged in the grooves provides for the axial mounting of the guide vanes. All these exemplary embodiments of the internal axial mountings can enable the axial play of the guide vanes to be reduced.
  • the bearing components that is to say the casing parts and/or the vane shank, may be hardened or provided with a coating of an abrasion-resistant material.
  • the axial and radial mounting of the adjusting ring can likewise be realized in a simple manner.
  • the adjusting ring 30 Before the casing parts 41 and 42 are pushed together in the axial direction, the adjusting ring 30 can be arranged together with the guide vanes between the casing parts or on one of the two casing parts. When said casing parts are pushed together, the final orientation of the adjusting ring in the axial direction is then effected automatically.
  • the adjusting ring 30 can be mounted in the axial direction from both sides by a corresponding bearing element 47 ′ and 47 ′′. As can also be seen from FIG.
  • the first axial bearing element 47 ′ is part of the first casing part 41
  • the second axial bearing element 47 ′′ is part of the second casing part 42 .
  • the radial mounting of the adjusting ring can be achieved in a simple manner by seating the adjusting ring on a circumferential projection 48 .
  • the bearing parts of the adjusting ring may also be hardened or coated.
  • a central casing body can be optionally arranged in the central region of the guide device, in which central region the tips of the plurality of guide vanes meet.
  • This central body lies concentrically on the axis of the compressor.
  • the central body is part of the casing, which in the region of the guide device forms the flow duct of the medium to be compressed.
  • the central body 44 can be positioned and held in place via one or more radially running casing ribs 43 .
  • the central body can also be positioned and held in place via the guide vane tips.
  • radially directed holes 441 can be incorporated in the central body 44 for this purpose, and shanks 16 specially designed for this purpose on the vane tips engage in said holes 441 .
  • This device having the guide vanes arranged radially around the central body also permits simplified fitting of the guide vanes, which can already be arranged around the central body 44 before insertion into one of the two casing parts 41 or 42 . The unit consisting of central body and all the guide vanes can then be directed in a single operation to the place intended for it.
  • corresponding holes may also be provided in the exemplary embodiment having a central body positioned and held by means of a retaining rib. They also serve in this case for simplified fitting by the guide vanes having the special vane tip shanks being inserted into the holes in the central body before they are then placed in the radially running apertures in the one casing part.
  • the vane tip shanks described may be fixedly connected to the tips of the guide vanes or else they may be rotatably mounted in holes provided for this purpose in the vane tips.
  • the shanks may also be fixedly connected to the central body, such that, during the fitting, the guide vanes can be slipped with their holes at the vane tips onto the shanks.
