Definitions

  • the invention relates to the field of turbomachines subjected to exhaust gases of internal combustion engines.
  • It relates to a guide device for generating a Vordralls in the intake of a compressor and an exhaust gas turbocharger with such a Vordrall guide.
  • Exhaust gas turbochargers are used to increase the performance of internal combustion engines. In modern internal combustion engines, the adaptation of the exhaust gas turbocharger to variable operating conditions will become more difficult.
  • a widely used option is the so-called variable turbine and / or compressor geometry.
  • the stator vanes are aligned more or less steeply with the flow upstream of the turbine wheel in accordance with turbine power requirements.
  • the vanes in the diffuser downstream of the compressor wheel are aligned more or less steeply to the flow.
  • Vordrall guide devices which produce in the Ansauge Scheme of the compressor in the intake air, or possibly the aspirated air-fuel mixture, a certain Vordrall, depending on the operating point more or less pronounced - or in opposite directions to the direction of rotation of the compressor wheel.
  • the object of the present invention is to provide a reliably operating over a long period of operation, easy to install predrirl guide with adjustable vanes.
  • the pre-whirl guide device further comprises a coaxial with the shaft axis of the compressor arranged, pivotable about this axis collar, and adjusting lever for transmitting torque from the adjusting ring on the blade shank of each vane.
  • vane shank and adjusting lever of each vane are formed in one piece.
  • the one-piece design of the vane reduces the number of joints, which has a positive effect on material wear. In addition, the number of components to be assembled is reduced. This simplifies the assembly and any service work on the guide.
  • the housing of the pre-whirl guide device according to the invention in which the guide vanes are rotatably mounted, comprises at least two parts joined together in the region of the bearings of the guide vane.
  • this makes it possible to assemble the guide vane, which is made in one piece with an integrated adjusting lever.
  • this makes it possible to support and secure the blade with the bearing point in the axial direction with respect to the axis of rotation of each moving blade.
  • the bearings can be protected with inserted bearing sleeves.
  • this axial bearing of the guide vanes takes place via projections on the shovel shafts and on the housing surrounding the shovel shafts. These projections extend in the radial direction with respect to the axis of rotation of the guide vane. The projections engage each other for the axial storage of the guide vane.
  • grooves can also be embedded in the housing and / or in the blade shafts, which cooperate with corresponding projections for the axial securing of the guide blade. If grooves are embedded both in the housing and the blade shafts, the axial bearing can be made with special bearing rings, which are arranged in the grooves.
  • Projections may also extend only partially around the respective vane shank.
  • Fig. 1 shows a section through a guide in the intake of a compressor.
  • Such compressors are, as described above, used in exhaust gas turbochargers to increase the performance of internal combustion engines.
  • the arrows in the figure indicate the flow path of the medium to be compressed, which is usually air or optionally 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 electric motors driven industrial compressors.
  • the guide device comprises a plurality of guide vanes 10 arranged aligned with respect to the compressor axis in the radial direction.
  • each of the guide vanes comprises a blade shank 12 with which the blade profile is rotatably mounted in a housing.
  • the blade profile can be rotated about the axis of the blade shank.
  • an adjusting ring 30 is provided, which is arranged concentrically to the axis of the compressor. By turning the adjusting ring 30, all blades are simultaneously adjusted about the respective axes of their shovel shafts.
  • the ball head 14 is guided in a groove 31 of the adjusting ring with two mutually parallel walls. In the groove of the ball head has the translational and rotational freedom of movement, which are necessary to implement the torque transfer.
  • the ball socket is at least partially made of a translationally displaceable sliding shoe 20th educated. If the adjusting ring 30 is rotated for adjusting the guide vanes, then 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 turned away, the position of the adjusting lever changes relative to the adjusting ring.
  • the translational displacement of the center of rotation of the ball head is made possible by sliding the sliding wall along the groove walls, while for the rotation of the ball head in the ball socket formed by the sliding shoe can rotate arbitrarily in any direction.
  • the shoe may also be formed in two parts by a ball socket half is arranged with a flat, sliding back on each side of the groove in the adjusting ring.
  • the torque is transmitted from the adjusting ring 30 to the blade shank 12 via a cylindrical pin 15 arranged at the free end of the adjusting lever 13.
  • the pin engages in a bore of a cylindrical sliding element 21 likewise mounted in a bore 32 in the adjusting ring 30.
  • the sliding cylinder 21 can be rotated in the bore 32 about its own axis and move along its own axis.
  • the bore in the sliding cylinder, which is provided for receiving the pin 15, is perpendicular to the axis of the sliding cylinder.
  • the pin can be rotated in this hole around its own axis and move along its own axis.

  • the blade profile 11, blade shank 12 and the adjusting lever 13, together with the attachment required for torque transmission, that is to say the ball head 14 or the pin 15, are integrally formed.
  • the entire guide blade 10 with its functional components cast or milled from one piece or force of several parts prior to installation in the housing force, shape or materially joined together in one piece.
  • the blade profile, the blade shank and the adjusting lever is poured as a piece and then driven the ball head or pin into a designated opening in the adjusting lever with interference fit or loosely inserted and welded or -gegossen.
  • the housing is divided according to the invention in the region of the bearing points of the guide vanes.
  • Fig. 2 how out Fig. 2 can be seen, at least two, with respect to the compressor axis joinable in the axial direction housing parts 41 and 42 are provided.

The two housing parts 41 and 42 are held together, for example, with connecting elements in holes 46 provided for this purpose or via other subsequently installed housing parts.
  • the storage of the guide vanes and the adjusting ring can be greatly simplified.
  • the blade shank in the axial direction instead of an additional bearing bush or with outboard bearing points in a simple manner to radially projecting housing edges 49 secure.
