Definitions

  • the invention relates to a burst protection device for radial turbines of turbochargers, according to the preamble of the claim 1.
  • DE-A1-42 23 496 describes a device for reduction the kinetic energy of bursting parts for those with high Speed revolving machines known.
  • This inside An axial turbine device consists of several interconnected guard rings between which each a crumple zone made of ductile material is trained.
  • Such a solution is for radial turbines not suitable because of their radial gas entry no burst protection devices in the radial area of the turbine can be used.
  • the invention tries to avoid all of these disadvantages. It is based on the task of being simple and safe Burst protection device for radial turbines of turbochargers create and thus the stability of the turbine, respectively the availability of the internal combustion engine connected to it to increase.
  • the first burst protection device is internal, i.e. arranged radially between the gas inlet and gas outlet housing and designed as a circumferential burst protection ring, wherein however, the guide vane channel is excluded.
  • the second burst protection device is external, i.e. Outside arranged on the gas inlet housing. It is as a spiral Formed sheet metal shell and extends at least over the axial expansion of the turbine wheel. Gas outlet side The burst protection ring also covers at least the axial extent of the turbine wheel.
  • burst protection device This creates a relatively simple and safe burst protection device created for radial turbocharger turbines.
  • the loose arrangement of the burst protection ring facilitates its assembly and thus leads to lower assembly costs. It comes to When the turbine wheel bursts, the burst protection ring takes one Most of the burst energy. Since the burst protection ring with Except for the guide vane duct, the entire length of the turbine wheel covers, can through the relatively narrow guide vane channel only smaller turbine fragments in the gas inlet casing to be flung. The big fragments which have a large kinetic energy are from Burst protection ring stopped. When smaller fragments Knock through the wall of the gas inlet housing, so these caught by the external burst protection device. Consequently can be achieved by combining internal and external burst protection devices even with very large released energies prevents turbine parts from being thrown out into the environment will.
  • a third burst protection device arranged and designed as a steel wire rope package.
  • the steel wire rope package is also in the cavity of Gas inlet housing and gas inlet housing, namely on the gas outlet housing side the burst protection ring arranged. It exists from several steel wire ropes, which are parallel to the direction of rotation of the turbine wheel and in at least one row are arranged side by side.
  • the exhaust gas turbocharger mainly consists of one shown compressor and designed as a radial turbine Exhaust gas turbine 1.
  • the radial turbine 1 has a turbine housing 2, with a spiral gas inlet housing 3 and a gas outlet housing designed as a gas outlet flange 4.
  • Turbine wheel 6 with blades 7 rotatably mounted.
  • shaft 5 is also not shown Compressor wheel arranged.
  • the gas inlet housing 3 goes downstream into a guide vane duct 8 over, in which a nozzle ring 9 between form Gas inlet housing 3 and gas outlet flange 4 is arranged.
  • the shaft 5 is in a bearing housing 11 by means of bearings 10 rotatably mounted.
  • the gas inlet housing 3 and the bearing housing 11 are via a clamping band arranged in the circumferential direction 12 connected to each other (Fig. 1).
  • the gas inlet housing 3 and the gas outlet housing 4 are releasably connected by screws 13. Both parts of the turbine housing 2 each have in their connection area a recess 14.
  • the recesses 14 form one common cavity 15, which is a first, as a circumferential Burst protection ring designed burst protection device 16, takes up loosely.
  • the burst protection ring 16 is thus radial between the gas inlet housing 3 and the gas outlet flange 4 arranged, however, the area of the guide vane channel 8 is excluded.
  • the burst protection ring covers the gas outlet side 16 the turbine wheel 6 in its axial extent completely from. Of course, he can the turbine wheel 6 on this Tower over the side.
  • Second burst protection device 17 arranged and detachable via a plurality of screws 18 with the Gas inlet housing 3 connected.
  • 17 becomes a high quality material, such as Hastelloy used. This can further increase the protective effect be improved.
  • the first and the second burst protection device 16, 17 a third burst protection device 19 gas outlet housing side of the Burst protection ring 16 arranged in the cavity 15.
  • This third Burst protection device 19 is designed as a steel wire rope package, which consists of several parallel to the direction of rotation of the Turbine wheel 6 and arranged side by side in a row Steel wire ropes 20 exists (Fig. 2).
  • the gas outlet flange 4 has four in its recess 14 parallel to the axis of rotation 21 of the turbine wheel 6 arranged ribs 22 with which the steel wire rope package 19 is positively connected (Fig. 3). These ribs are stiffening, so that an additional Burst protection is achieved.
  • a third burst protection device 19 is reduced the likelihood of turbine part leakage out of the turbine housing 2 and thus increases safety of the exhaust gas turbocharger.
