Abstract: The exhaust-gas turbine comprises a turbine wheel arranged on a shaft, a bearing casing for the bearing arrangement of the rotatable shaft, a gas-inlet casing supported on the bearing casing and concentrically surrounding the bearing casing in the supporting region, and a centering ring for centering the gas-inlet casing relative to the shaft mounted in the bearing casing. The centering ring and either the bearing casing or the gas-inlet casing comprise grooves and either radially or axially unidirectional centering lugs for engaging in the grooves. Due to the radially or axially unidirectional centering lugs with corresponding grooves, at least one of the connections between the bearing casing and the centering ring and the centering ring and the gas-inlet casing is not positive-locking, as a result of which any desired positioning of the gas-inlet casing relative to the bearing casing is made possible.

Abstract: The shaft (1) is connected to the shaft attachment (2) by means of a thread. A bore (20) with an internal thread is incorporated in the shaft attachment and the shaft has a corresponding stem (10) which can be introduced into the threaded bore and has an external thread. An axial stop (11, 21) is arranged in each case on the shaft and on the shaft attachment. The internal and external threads have torque-transmitting flanks which are flat toward the axis and which can be connected to one another frictionally by means of radial pressure by mutual rotation of shaft and shaft attachment with interaction between the axial stops. Owing to the small angle between the load-bearing flanks and the axis, the radial pressure decisive for the torque transmission is correspondingly greater than in conventional threaded connections. As a result, the axial prestressing force between the two parts to be connected can be correspondingly reduced.

Abstract translation: 轴（1）通过螺纹连接到轴附件（2）。 具有内螺纹的孔（20）被并入轴附件中，并且轴具有相应的杆（10），其可以被引入螺纹孔并具有外螺纹。 每个壳体中的轴和轴附件都布置有轴向止动件（11,21）。 内部和外部螺纹具有朝向轴线平坦的扭矩传递侧面，并且可以通过径向压力彼此相互连接，通过轴和轴附件的相互旋转与轴向止动件之间的相互作用。 由于承载侧面和轴线之间的角度小，所以转矩传递的径向压力相应地大于常规的螺纹连接。 结果，可以相应地减少要连接的两个部件之间的轴向预应力。

The catch ring having an inner contour in the region of the central opening. The radial projection on the shaft is provided with an outer contour. The inner contour on the catch ring and the outer contour on the shaft are configured such that, during mounting of the shaft and of the turbine wheel connected thereto and in at least one specified angle position of the shaft with respect to the housing, the radially outwardly protruding projection on the shaft can be passed in an axial direction through the central opening of the housing element. The radially outwardly protruding projection abuts in the axial direction against the housing element in specified angle positions of the shaft with respect to the housing.

Abstract: A sound attenuator on the intake side of a compressor of an exhaust-gas turbocharger includes a tubular sound attenuator housing, which encases a flow duct between a face-side inlet opening and a rear-side outlet opening. A holding plate is provided in the sound attenuator housing in the flow direction and is perforated in the flow direction. For example, the holding plate can have a multiplicity of holes extending in the flow direction. The sound attenuator on the intake side of the compressor of an exhaust-gas turbocharger has a compact, lightweight and inexpensive structural form. The intake air is subjected to low resistance as it flows through the attenuation elements.

Abstract: A device for sealing a bearing housing, which holds lubricating oil, from which a rotor supported inside the housing of an exhaust gas turbocharger is guided into a compressor housing, loadable by a mass flow of a charger. The device includes a fixed partition with a wall extension, a sealing disk fastened on a shaft of the rotor, a separating gap arranged between the sealing disk and the wall extension, and a drip device connected to an oil-collecting channel and directs lubricating oil collected in the oil-collecting channel into an oil drain by gravity. The drip device includes a drain-off surface for lubricating oil, which has a large axial distance from a rotating sealing disk which delimits the separating gap. Lubricating oil which can penetrate into the separating gap is guided into an oil drain of the bearing housing without interacting with the sealing disk.

Abstract: A compressor casing includes a casing insert with a flexible element in the force flux between the insert wall contour and the outer compressor casing. The flexible element is assembled from a support ring and ribs, wherein the ribs axially in front of the support ring and the ribs axially behind the support ring are arranged in an offset manner in relation to each other. Due to the arrangement of the ribs in an offset manner, the axial force flux between the insert wall contour and the outer compressor casing is deflected twice, and an axially compliant flexible construction is achieved.

Abstract: By means of a pre-swirl device, in steady-state engine operation, the rotational speed lines of the compressor are moved, by increasing the swirl at the compressor inlet in the rotational direction of the compressor, to such an extent that the steady-state operating point of the compressor comes to rest approximately at the absorption limit of the compressor. In this way, the level of the charge pressure can be adjusted in a controlled fashion to the value required for the respective engine operating point. In the event of a sudden increase in the engine load, it is possible by resetting the pre-swirl grate to generate a charge pressure increase without a time-consuming rotor acceleration. The pre-swirl device therefore simultaneously assumes the functions of charge pressure and engine load control.

Abstract: The nozzles are in the form of blowing-in openings in the housing wall which bounds the flow channel. The blowing-in openings are fed directly by means of air which is extracted from the flow channel downstream from the diffusor. This air is at a higher pressure than the flow in the flow channel upstream of the diffusor. This results in a passive, dynamic stabilization system for a compressor stage in the high pressure-ratio range, which does not require any additional control or actuating elements.

Abstract: The use of spring clamping clips between two adjacent guide vane shafts leads to a defined force on the bearing points of the guide vane in the guide bush. The seating force, resulting from the clamping force and the flow-related lift/drift forces, of the guide vane in the guide bush is therefore always positive and the guide vane rests constantly in the guide bush.
