摘要： An exhaust gas turbocharger has a turbine with a turbine wheel. The turbine wheel is axially mounted in a turbine housing and has turbine blades, each with a leading edge for a flow of media. An adjustable guide grate with a plurality of stator vanes adjusts a flow cross-section relative to the leading edge of the turbine wheel. Each stator vane has a vane rear edge facing the turbine wheel. A plane is defined by a rotational axis of the turbine wheel and at least one point on the leading edge, wherein a projection of the leading edge onto the plane is axially inclined relative to the rotational axis of the turbine wheel at least in one region, and the stator vanes are arranged radially about the turbine wheel at least in the region.

摘要： A rotor of an exhaust-gas turbocharger includes a rotor hub and rotor blades disposed on the rotor hub. The rotor blades have a blade thickness distribution selected in such a way that the rotor blades have along their extent from a fluid inlet or leading edge to a fluid outlet or trailing edge at least one transition between a stiffness or rigidity-oriented blade thickness distribution and an inertia and stress-oriented blade thickness distribution over the height of the blade.

摘要： A turbocharger has a shaft with a rotational axis, a radial/axial turbine wheel which is arranged in a turbine housing and which is connected to the shaft in a non-rotatable manner, and a bearing housing which adjoins the turbine housing and which contains a lateral wall facing the turbine housing. A sub-region of the lateral wall of the bearing housing forms a sub-region of the rear wall of the turbine housing. The sub-region of the bearing housing has two sub-sections, one of which runs diagonally to the rotational axis in an inflow direction of an exhaust gas flow conducted into the turbine housing and the second of which runs in a radial direction relative to the rotational axis of the shaft and parallel to the rear wall of the turbine wheel. The two sub-sections are connected to each other via an exhaust gas flow separation edge of the bearing housing.
