Definitions

  • the invention relates to a turbomachine, in particular an exhaust gas turbocharger according to the preamble of claim 1.
  • Such a turbomachine in the form of a turbocharger is known from DE 100 28 161 C2 DE 102 97 203 T5.
  • the turbine-side seal between the rotor shaft and the bearing housing, which can be seen there, is accomplished by means of a labyrinth seal. Leakage is thereby possible both in the direction of the turbine wheel and in the direction of the bearing housing.
  • the invention relates to a turbomachine, in particular in the form of an exhaust gas turbocharger, for example for motor vehicles, with a turbine-side rotor shaft sealing system, which may preferably be in the form of a gas-lubricated mechanical seal.
  • This rotor shaft sealing system makes it possible to seal spaces which are exposed to media (liquids and / or gases) which are subject to different pressures, wherein a rotating shaft is guided through a housing wall which, in the case of a turbocharger, is a rotating shaft Rotor shaft acts.
  • the turbomachine according to the invention or the rotor shaft sealing system according to the invention is suitable for high temperatures (up to 900 ° C.) and extremely high rotational speeds (up to 300,000 min -1) and peripheral speeds up to 550 m / s suitable.
  • a rotating mating ring is fixed (with sampling) on the rotor shaft, which can be achieved for example by shrinking, screwing or pressing.
  • a stationary slide ring with feathering preferably in the form of a metal diaphragm bellows, is screwed into the housing via a screw-in sleeve. The mating ring together with the sliding ring in the operation of the turbocharger dynamic and the metal diaphragm bellows with the graphite ring represents the static seal.
  • the metal diaphragm bellows is a biasing device that realizes a resilient contact.
  • this part of the entire sealing device as a cartridge.
  • a preload arises in the metal diaphragm bellows so that axial play and possible wear of the sliding surfaces can advantageously be minimized.
  • the turbocharger is at a standstill, the mating ring and the sliding ring form a static seal between the rotor shaft and the bearing housing.
  • the rotation of the counter-ring 11 generates by its axial sampling a pressure build-up in the contact surface with the sliding ring, so that forms a small axial gap.
  • a running shaft sealing device is defined as a self-negotiable part.
  • a turbomachine 1 according to the invention is shown, which is formed in this example as an exhaust gas turbocharger.
  • This exhaust-gas turbocharger contains, in addition to the following details of a running-shaft sealing device 8 according to the invention, of course all the usual components which, however, are not shown in part in order to simplify the illustration in FIG. 1, since these are dispensable for the explanation of the present invention.
  • FIG. 1 shows the rear wall 2 of a compressor housing (not shown) and a compressor wheel 3 arranged in this compressor housing.
  • a turbine wheel (rotor) 4 is shown, which is arranged in a turbine housing, not shown.
  • the compressor wheel 3 and the turbine wheel 4 are mounted on a rotor shaft 6 at its opposite ends, as shown in detail in FIG.
  • the rotor shaft 6 is guided via a suitable bearing arrangement in a bearing housing 5.
  • the bearing housing 5 has a turbine-side end region 7, which is arranged adjacent to the turbine wheel 4 and which is protected by a heat shield 26 against excessive heating.
  • the turbine-side end region 7 has a receiving space 30 for a rotor shaft sealing device 8, which in FIG. 1 is marked with the detail X and will be explained below with reference to the enlarged view of FIG. 2 in detail.
  • the rotor shaft sealing device 8 is constructed as a gas-lubricated sliding ring sealing device comprising a static sealing arrangement and a dynamic sealing arrangement.
  • a counter-ring 11 which comprises a fixing section 12 which can be fixed (shrunk, screwed or pressed on) on a first rotor shaft area 9.
  • the counter ring 11 further comprises a preferably arranged at right angles to the fixing portion 12 annular collar 13 which abuts axially in part on a transition region 31 of the rotor shaft 9, which leads to a second rotor shaft region 10 having a larger diameter than that first rotor shaft area 9.
  • the rotor shaft sealing device 8 also has a sliding ring 14, which is screwed to a pretensioning device, preferably in the form of the illustrated metal diaphragm bellows 19, via a screw-in sleeve 20 with external thread 27 in the bearing housing 5 or in the end section 7 of the bearing housing 5.
  • the slip ring 14 has a main body 16 and a nose 15 extending radially outward from the main body 16. This arrangement results in a contact surface, which assigns to the collar 13 of the counter-ring 11 and comes with this, as shown in Fig. 2, in the assembled state in contact.
  • Fig. 2 also illustrates a graphite ring 18 which is braced in screwed-in screw 20 in the housing 5.
  • an adapter plate 17 is arranged, which is fixedly connected to the sliding ring 14.
  • the spring element 21 in turn is welded to a welding lip 25 of the screw 20.
  • the welded individual spring elements 21 to 23 of the bellows 19, the adapter plate 17 and the screw 20 and the slide ring 14 is a preassembled cartridge, which adjusts a bias of the sliding ring 14 when mounting this cartridge through the metal diaphragm bellows 19 , so that the axial play and possible wear of the sliding surfaces can be minimized.
  • the adapter plate 17 has an annular body 29 which is arranged around the rotor shaft section 10 of the rotor shaft 6 and which is provided at its radially outward-pointing end with the welding lip 24 and the connecting section 28 is.
