Definitions

  • the turbine wheel 3 is made of a metal aluminide or a high-temperature-resistant titanium-aluminum alloy.
  • the advantage of these materials is, in addition to a low thermal expansion, in their favorable strength-density ratio, that is, they have high strength at low density.
  • the mass of the turbine wheel 3 is to be reduced by about half.
  • the moment of inertia of the power tool 1, which characterizes the response of the exhaust gas turbocharger can be substantially reduced.
  • the turbine wheel 3 has an opening 6 which completely penetrates the turbine wheel 3 in the direction of the axis of rotation 5 and which the shaft 4 can be designed to receive.
  • the compressor 2 is positioned at a first end 7 opposite ⁇ lying second end 8 of the shaft.
  • a sleeve 10 is arranged, which serves a low-friction mounting of the shaft 4 in the bearing section.
  • An advantage of the second variant is the fact that the sleeve 10 is to be designed with a small wall thickness W, so that even at high speeds of the power tool 1, a slight elongation of the sleeve 10 due to the heat development during operation of the power tool 1 is to be expected.
  • one is Temperature load on the collar 13 is lower, so that an improved centering of the turbine wheel 3 is formed to the shaft 4.
