  • Rotor for a turbine or a compressor or a turbine/compressor geometry
    Patent number: 9803482
    Abstract: A rotor for at least one of a turbine and a compressor of a supercharging device may include a shaft defining an axis of rotation and at least one impeller. The at least one impeller may have a thread which is arranged coaxially to the axis of rotation. The shaft may include a complementary thread which is arranged coaxially to the axis of rotation. The shaft and the at least one impeller may be secured together via the respective threads. The shaft and the at least one impeller may be fixed with respect to one another via at least one of a soldered connection, a welded connection, an adhesive bond, a clamped connection and a crystallization connection.

  • EXHAUST-GAS TURBOCHARGER
    Publication number: 20160177726
    Abstract: An exhaust-gas turbocharger may include a compressor wheel and a turbine wheel connected fixedly in terms of rotation to the compressor wheel via a shaft. The turbine wheel may have a hub, a disc-like wheel back, and a plurality of blades extending radially from the hub and axially from the wheel back. The wheel back may include at least one cut-out region of reduced axial thickness.

  • TURBINE WHEEL OF AN EXHAUST GAS TURBOCHARGER AND ASSOCIATED PRODUCTION METHOD
    Publication number: 20160010457
    Abstract: A turbine wheel for an exhaust gas turbocharger may include a body composed of a TiAl alloy via at least one of metal injection moulding, selective laser melting and electron beam melting. The body may include a plurality of blades each having an outlet blade root and an outlet blade tip disposed radially away from a rotation axis with respect to the outlet blade root. The body may have a quotient Q of a diameter dS defined by each of the outlet blade tips to a diameter dN defined by each of the oulet blade roots corresponding to the following relationship: Q=dS/dN>3.85.
