Definitions

  • the invention relates to an axial turbine for exhaust gas turbochargers according to the preamble of patent claim 1.
  • the inner wall of the gas deflection channel arranged between the turbine guide apparatus and the turbine blades is rigid and immovable.
  • a swirl loss occurs due to the gas friction on this wall. Due to the high peripheral speed of the gas, which increases radially inwards, this inner wall of the gas deflection channel causes relatively high friction losses.
  • the isentropic we The degree of efficiency of the turbine drops additively by about 2% to 5%.
  • the invention is therefore based on the object of creating an axial turbine in which the swirl loss in the gas deflecting duct is reduced to a minimum, and good efficiency is thereby achieved.
  • Fig. 1, 1 denotes the turbocharger axis.
  • the axial turbine shown with radial gas inflow is connected via the turbine housing 7 to an exhaust line, not shown, of a supercharged diesel engine.
  • the turbocharger shaft 2 is supported in the turbine housing 7 by means of shafts, bearings 10 and carries a turbine disk 3 provided with the turbine blades 4. Gas flow upstream of the turbine blades 4 through which axial flow flows are arranged in the annular deflection channel 7a of radial turbine blades 5.
  • a sealing air channel 8 and an air discharge channel 9 are arranged in the turbine housing 7.
  • the inner wall of the rotationally symmetrical exhaust gas deflecting duct 7b is designed as a deflecting collar 6 rotating with the turbocharger shaft 2.
  • This deflecting collar 6 is rigidly connected to the turbocharger shaft 2 by means of screws 12.
  • the outside diameter of the rotating deflection collar 6 is larger than the diameter of the turbine disk 3 and can at most be the same as the outside diameter of the turbine rotor.
  • An element for contactless sealing of the exhaust gas deflection channel is provided between the rotating deflection collar 6 and the housing 7. This element consists of two labyrinth seals 11, 11 ', which are arranged on a cylindrical, concentric, inwardly open surface of the deflecting collar 6.
  • a sealing air duct 8 arranged in the turbine housing 7 is connected to a radial gap 15 arranged between the labyrinth seal 11 facing the turbine and the labyrinth seal 11 'facing away from the turbine.
  • An air discharge duct 9 arranged in the turbine housing 7 is connected to an air space 13.
  • the sealing air supply through the sealing air duct 8 serves to cool the turbocharger shaft 2 and the turbine disk 3 and prevents the exhaust gas from flowing out of the exhaust gas deflection duct 7b through the air space 13 to the shaft bearing 10 and to the environment.
  • the resulting axial force acting on the turbocharger shaft 2 is, among other things, a function of the pressure distribution on the two sides of the deflecting collar 6. Since the labyrinth seals 11 are located radially far outside, this resulting axial force is greatly reduced and corresponds approximately to that of a radial turbine. Due to the flow losses in the labyrinth seal 11, the air pressure in the air space 13 behind the deflecting collar 6 is approximately reduced to the ambient pressure. As a result, the axial force on the turbocharger shaft is small.
  • the sealing air consumption in this version is somewhat larger than in the versions without a rotating deflection collar 6.
  • the element for contactless sealing of the deflection channel 7b consists of a labyrinth seal 11 concentrically arranged in a plane normal to the axis.
  • the labyrinth seal 11 is arranged on the outside diameter of the rotating deflection collar 6.
  • the small amount of exhaust gas flowing inwards from the exhaust gas deflection duct 7b through the labyrinth seal 11 is discharged into the discharge duct 9 with the sealing air coming radially from the inside out.
  • the sealing air consumption in this version is smaller than that in the versions without a rotating deflecting collar 6. This sealing air consumption is mainly determined by the necessary cooling of the deflecting collar.
  • a very small amount of engine exhaust gas is lost here through the labyrinth seal 11. This loss of volume is also negligible due to the low gas density.
  • a main advantage of this design is that the axial force on the turbocharger shaft is practically eliminated.
