Abstract
Description
Die Erfindung betrifft ein Turbinengehäuse für einen Abgasturbolader.The invention relates to a turbine housing for an exhaust gas turbocharger.
Bei in Abgasturboladern verwendeten, aus Blechteilen zusammengesetzten Turbinengehäusen kommt es im Betrieb oftmals zu unerwünschten Verformungen des ebenfalls aus Blech bestehenden Konturbereiches aufgrund der auftretenden thermischen Belastungen und/oder aufgrund von auftretenden Drucklasten. Unter dem Konturbereich des Turbinengehäuses wird dabei der dem Turbinenrad nächstliegende Bereich des Turbinengehäuses verstanden, welcher eine Dichtkontur aufweist. Diese Dichtkontur, die am Ende des schneckenförmig verlaufenden Einlasskanals des Turbinengehäuses positioniert ist, definiert den Konturspalt der Turbine, welcher die strömungstechnischen Eigenschaften und damit die Thermodynamik der Turbine prägt. Unerwünschte Verformungen des Konturbereiches des Turbinengehäuses führen zu einer Verschlechterung der Thermodynamik und ggf. auch zu einem Anstreifen des sich im Betrieb mit hoher Drehzahl drehenden Turbinenrades an das Blech im Konturbereich des Turbinengehäuses. When used in exhaust gas turbochargers, composed of sheet metal parts turbine housings, there are often undesirable deformations of the also consisting of sheet metal contour area due to the thermal stresses occurring and / or due to pressure loads occurring in operation. In this case, the contour region of the turbine housing is understood to be the region of the turbine housing which is closest to the turbine wheel and has a sealing contour. This sealing contour, which is positioned at the end of the spiral-shaped inlet channel of the turbine housing, defines the contour gap of the turbine, which characterizes the fluidic properties and thus the thermodynamics of the turbine. Unwanted deformations of the contour region of the turbine housing lead to a deterioration of the thermodynamics and possibly also to a rubbing of the rotating at high speed turbine wheel to the plate in the contour region of the turbine housing.
Ein derartiges Anstreifen des Turbinenrades an das Blech kann durch eine Vergrößerung des Konturspaltes in radialer und axialer Richtung verhindert werden. Eine derartige Vergrößerung des Konturspaltes wirkt sich jedoch negativ auf die Thermodynamik der Turbine aus. Darüber hinaus muss für jede Radgeometrie eine eigene Blechkontur hergestellt werden. Dies wiederum ist mit hohen Werkzeugkosten verbunden. Des Weiteren kann die Maßhaltigkeit der Kontur gegenüber dem Turbinenrad nachteilig sein, da sich die Toleranzen der einzelnen miteinander verbundenen Blechteile addieren, was wiederum einer Vergrößerung des Konturspaltes bedarf und mit negativen Auswirkungen auf die Thermodynamik einhergeht. Such a rubbing of the turbine wheel against the sheet metal can be prevented by an enlargement of the contour gap in the radial and axial direction. However, such an enlargement of the contour gap has a negative effect on the thermodynamics of the turbine. In addition, a separate sheet metal contour must be produced for each wheel geometry. This in turn is associated with high tooling costs. Furthermore, the dimensional accuracy of the contour relative to the turbine wheel can be disadvantageous, since the tolerances of the individual interconnected sheet metal parts add up, which in turn requires an enlargement of the contour gap and is associated with negative effects on thermodynamics.
Einem Anstreifen des Turbinenrades an das Blech kann auch dadurch entgegengewirkt werden, dass das Blech im Konturbereich des Turbinengehäuses entsprechend dickwandig ausgebildet wird. Dies wirkt zwar einer Verformung des Konturbereiches entgegen, erhöht jedoch die Herstellungskosten des Turbinengehäuses. Stripping of the turbine wheel to the sheet can also be counteracted by the fact that the sheet is formed corresponding thick-walled in the contour region of the turbine housing. Although this counteracts a deformation of the contour region, but increases the manufacturing cost of the turbine housing.
Um eine andere Turbinenrad-Geometrie verwenden zu können, kann ein Ersatz des den Konturbereich bildenden Blechteiles durch ein entsprechend anderes Blechteil erfolgen, dessen Form an die andere Turbinenrad-Geometrie angepasst ist. In order to use a different turbine wheel geometry, a replacement of the sheet metal part forming the contour region can be done by a correspondingly different sheet metal part whose shape is adapted to the other turbine wheel geometry.
Des Weiteren ist es zu einer Reduzierung der Verformungen des den Konturbereich bildenden Blechteiles bereits bekannt, doppelwandige Turbinengehäuse mit Schiebesitzen herzustellen, die die auftretenden Lasten aufnehmen. Auch ein derartiges Vorgehen erhöht die Herstellungskosten des Turbinengehäuses. Furthermore, it is already known to produce a reduction in the deformations of the contour portion forming sheet metal part, double-walled turbine housing with sliding seats that absorb the loads occurring. Such a procedure also increases the manufacturing costs of the turbine housing.
Aus der
Die Aufgabe der Erfindung besteht darin, die Thermodynamik einer Turbine bei vergleichsweise geringen Herstellungskosten des Turbinengehäuses zu verbessern. The object of the invention is to improve the thermodynamics of a turbine at a comparatively low manufacturing cost of the turbine housing.
Diese Aufgabe wird durch ein Turbinengehäuse mit den im Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben. This object is achieved by a turbine housing with the features specified in claim 1. Advantageous embodiments and further developments of the invention are specified in the dependent claims.
Die Vorteile der Erfindung bestehen insbesondere darin, dass durch eine vom Anwendungsfall abhängige Wahl der Geometrie, des Werkstoffes, der Materialdicke und/oder der Materialverteilung des Konturbauteils die Thermodynamik der Turbine gezielt verbessert werden kann. Des Weiteren werden die Herstellungskosten eines Turbinengehäuses niedrig gehalten. The advantages of the invention are, in particular, that the thermodynamics of the turbine can be purposefully improved by a choice of the geometry, the material, the material thickness and / or the material distribution of the contour component dependent on the application. Furthermore, the manufacturing cost of a turbine housing is kept low.
Weitere Vorteile der Erfindung bestehen darin, dass durch eine Bearbeitung des den Konturbereich bildenden Bauteils und des Lagergehäusesitzes des Turbinengehäuses in einer Aufspannung der Konturbereich relativ zum Turbinenrad präzise vorgefertigt werden kann. Auch dies verbessert die Thermodynamik des Turbinengehäuses. Further advantages of the invention are that can be precisely prefabricated by machining the contour region forming member and the bearing housing seat of the turbine housing in a single clamping of the contour region relative to the turbine wheel. This also improves the thermodynamics of the turbine housing.
Des Weiteren können mit demselben Bauteil verschiedene Gehäusekonturen durch eine mechanische Nachbearbeitung des Bauteils dargestellt werden. Dies hat den Vorteil einer deutlichen Reduzierung der Teilekosten und der benötigten Teilevielfalt. Furthermore, with the same component different housing contours can be represented by a mechanical post-processing of the component. This has the advantage of a significant reduction in parts costs and the required variety of parts.
Ferner können Gewichts- und Materialeinsparungen erreicht werden. Furthermore, weight and material savings can be achieved.
Bilden darüber hinaus der Wastegatekanal und/oder die Wastegatebuchse einen integrierten Bestandteil des Konturbauteils, dann können die Herstellungskosten eines Turbinengehäuses niedrig gehalten werden und die Maßhaltigkeit des Turbinengehäuses weiter verbessert werden. In addition, if the wastegate channel and / or the wastegate socket form an integral part of the contour component, then the manufacturing costs of a turbine housing can be kept low and the dimensional accuracy of the turbine housing can be further improved.
