Abstract: The exhaust-gas turbine comprises a turbine casing (1), a shaft (3) rotatably mounted in a bearing housing (4), a turbine wheel (5) arranged on the shaft, and a heat-protection wall (2), the heat-protection wall defining with the turbine casing an inflow passage (6) leading to the turbine wheel. The heat-protection wall has two seatings, the first seating resting on the bearing housing (4) and the second seating resting on the turbine casing (1). If the heat-protection wall (2) becomes hot, the two seatings are pressed against the bearing housing and the turbine casing. The turbine casing is pressed outward in the radial direction. Centering of the heat-protection wall (2) and thus also of the turbine casing (1) is ensured by the radially inner seating of the heat-protection wall.

Abstract: An exhaust turbocharger comprises a turbine having a turbine wheel and a compressor having a compressor wheel. The turbine wheel and the compressor wheel are connected by a shaft rotatably mounted in a bearing housing. A means for axially securing the shaft and the turbine wheel connected thereto is provided between the compressor wheel and the turbine wheel. The means limits an axial movement of the shaft and of the turbine wheel connected thereto in the direction of the turbine in the event of the compressor wheel bursting. The means comprises a component which is screwed onto the shaft during mounting and is fixed in the axial direction in the housing.

Abstract: A shaft seal of the rotating wheel shaft of a turbomachine includes a rotating wheel-side seal and a bearing-side seal between the bearing housing and the shaft. An oil outlet chamber is arranged between the rotating wheel-side seal and the bearing-side seal. The oil outlet chamber is delimited by a third seal between the bearing housing and the shaft, and a gas discharge chamber is arranged between the third seal and the rotating wheel-side seal. The construction is actively cooled by means of at least one splash oil bore in the region of the oil drain channel, as a result of which coking of the shaft seal can be prevented. The third seal separates the oil issuing from the oil outlet chamber from the gas issuing from the gas discharge chamber.

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: The means of sealing the compressor wheel with respect to the bearing housing includes an annular sealing element which forms a sealing boundary face with a shaft edge and to which a spring force is applied in the direction of the shaft edge. The external spring force neither compensates or amplifies the pressure forces acting on the sealing element, irrespective of the direction of the difference in pressure. As a result, the sealing of the oil space in the bearing housing of the exhaust gas turbocharger with respect to the shaft is not influenced, or is influenced only to a small degree, by the pressure fluctuations in the wheel back space of the compressor.

Abstract: Numerous cavities exist in a turbocharger for reasons of construction. If such cavities are filled with particles, inexpensive particle vibration dampers can be realized. Moreover, advantages with regard to additional containment security result in the case of possible bursting of the compressor wheel, and also with regard to noise suppression.

Abstract: A stator arrangement, or distributor, for a turbine machine is disclosed which includes a guide blade. The blade shaft is supported to be able to pivot around the pivot axis, with a part which is to be guided being situated to the outside. The pivoting device contains a setting ring which is located outside a flow channel and which can be pivoted around the turbine axis, and adjusting levers which transmit torque from the setting ring to the blade shaft of each guide blade. The adjusting lever is slipped with one end onto the blade shaft. The other end can be configured as a ball head, the adjusting levers being guided in a groove of the setting ring. The surface which acts on the ball head of the adjusting lever for transmission of torque from the setting ring to the blade shaft of each guide blade can be configured as a ball socket. Exemplary embodiments can yield a uniform large-area pressure distribution by which the wear of the parts which press on one another can be distinctly reduced.
