Definitions

  • the invention relates to a turbocharger according to the preamble of claim 1.
  • a generic turbocharger is from the US 5 176 497 A .
  • EP 1 394 387 A US 2000/001522 A1 or the WO 99/07982 A known.
  • the piston ring recesses or grooves were always arranged in the rotor shaft.
  • one respective groove is provided per piston ring or that two piston rings are arranged in a groove.
  • the turbinenradnahe Kolbenringnut requires a constructive minimum distance from the turbine and the connection pin is kept axially as short as possible at the Turbinenraapp, it is not yet possible to introduce two grooves in the shaft area without weakening the shaft in cross section or without axially extending the shaft, which is very negative Effects on rotor bearing stability. If the turbine wheel and the rotor shaft connected by a weld, it was not possible, the Kolbenringnuten arbitrary
  • the area of the weld is not suitable for the attachment of the grooves.
  • turbocharger for an internal combustion engine according to the preamble of claim 1, which has a turbine rotor, which allows without increasing the axial rotor length to avoid deterioration of the arrangement by the attachment of piston ring grooves.
  • Fig. 1 an inventive turbocharger 1 is illustrated in a partially broken view.
  • the turbocharger 1 has a turbine 2 which comprises an exhaust gas inlet opening 3 and an exhaust gas outlet opening 4.
  • a turbine wheel 5 is disposed in the turbine housing of the turbine 2, which is fixed to one end of a rotor shaft 6.
  • a plurality of blades is arranged in the turbine housing between the exhaust gas inlet opening 3 and the turbine wheel 5.
  • the turbocharger 1 has a compressor 8, which comprises a compressor wheel 9, which is fastened on the other end of the rotor shaft 6 and arranged in the compressor housing 8 of the compressor.
  • turbocharger 1 also includes all other conventional components of a turbocharger, such as a bearing housing with a bearing housing unit, etc., which, however, will not be described below since they are not necessary for the explanation of the principles of the present invention.
  • FIG. 2 is a part of a turbine rotor 10 shown in section, the rotor shaft 6 and the turbine wheel 5 with the inventive arrangement of Kolbenringeinsstichen 11, 11 ' on an extended, one-piece connecting pin 17 of the turbine wheel 5 shows.
  • this shaping of the turbine wheel 5 it is achieved that all structurally required piston ring punctures 11, 11 'are formed in the heat-resistant material of the turbine wheel 5 which is more heat-resistant than the material alloy of the rotor shaft 6.
  • This arrangement of Kolbenringeinsstiche 11, 11 'in identical material creates identical tribological conditions for the piston rings to be installed therein (which are not shown in this figure).
  • the turbine wheel 5 has a cylindrical cavity 15 whose depth L, measured from the axial shaft-side end face 14 of the connecting pin 17 to a wheel back 13 of the turbine wheel 5, is smaller than a length B of the connecting pin 17.
  • the rotor shaft 6 and the turbine wheel 5 can be connected to each other at the connection plane A either by friction welding or electron beam welding.
  • the rotor shaft 6 has a short stub shaft 16.
  • the inventive design of the connecting pin 17 of the turbine wheel 5 has the advantage that it can be easily pressed onto the stub shaft 16 and the risks of the occurrence of stresses during the welding process and possible resulting cracking can be minimized by the existing at the connection level A on both components material or wall thicknesses.
