Die vorliegende Erfindung beschäftigt sich mit dem Problem, für einen Rotor der eingangs genannten Art bzw. für einen damit ausgestatteten Abgasturbolader eine verbesserte oder zumindest eine andere Ausführungsform anzugeben, die sich insbesondere dadurch auszeichnet, dass sie vergleichsweise preiswert herstellbar ist.The The present invention addresses the problem of for a rotor of the type mentioned or for an exhaust gas turbocharger equipped therewith an improved or specify at least one other embodiment, which characterized in particular by the fact that they are comparatively inexpensive can be produced.
Erfindungsgemäß wird dieses Problem durch die Gegenstände der unabhängigen Ansprüche gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.According to the invention this problem by the objects of the independent Claims solved. Advantageous embodiments are the subject of the dependent claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, die Verbindung zwischen dem Turbinenrad aus einem Titanaluminid und der Welle aus Stahl mit Hilfe einer Buchse zu realisieren, die einerseits mit der Welle und andererseits mit dem Turbinenrad fest verbunden ist. Die Buchse ist dabei koaxial zwischen der Welle und dem Turbinenrad angeordnet, so dass die Verbindungen radial wirken. Radiale Verbindungen können im Vergleich zu axialen Verbindungen deutlich höhere Momente übertragen, da sie insbesondere in axialer Richtung quasi beliebig groß dimensioniert werden können. Die Verwendung einer bezüglich der Welle und des Turbinenrads ein separates Bauteil bildenden Buchse ermöglicht bzw. erleichtert es insbesondere, die Buchse hinsichtlich ihrer Werkstoffauswahl zu optimieren. Die Optimierung kann dabei hinsichtlich einer möglichst festen und dauerhaften Verbindung zwischen Buchse und Turbinenrad einerseits und zwischen Buchse und Welle andererseits ausgerichtet sein. Die Buchse kann bspw. mit der Welle verlötet oder verschweißt sein. Lötverbindungen und Schweißverbindungen lassen sich prozesssicher und preiswert realisieren.The Invention is based on the general idea, the connection between the turbine wheel of a titanium aluminide and the shaft of steel with Help to realize a socket, on the one hand with the shaft and on the other hand firmly connected to the turbine wheel. The socket is arranged coaxially between the shaft and the turbine wheel, so that the compounds act radially. Radial connections can transmit significantly higher torques compared to axial connections, because they dimensioned quasi arbitrarily large, especially in the axial direction can be. The use of a re the shaft and the turbine wheel, a separate component forming socket allows or facilitates in particular, the socket to optimize their material selection. The optimization can doing so in terms of a solid and durable Connection between bush and turbine wheel on the one hand and between Socket and shaft on the other hand be aligned. The socket can, for example. be soldered or welded to the shaft. solder connections and welded joints can be reliably and inexpensively realize.
Alternativ ist es ebenso möglich, die Buchse mit dem Turbinenrad zu versintern. Dies ist von besonderem Vorteil, wenn auch das Turbinenrad als Sinterteil ausgestaltet ist, also pulvermetallurgisch hergestellt ist. Beispielsweise kann die Buchse in den Sintergrünling des Turbinenrads eingesetzt werden und gemeinsam damit gesintert werden. Hierdurch können besonders intensive, tragfähige stoffschlüssige Verbindungen realisiert werden.alternative it is also possible to use the bushing with the turbine wheel sinter. This is of particular advantage, although the turbine wheel is designed as a sintered part, so produced by powder metallurgy is. For example, the bushing in the Sintergrünling the turbine wheel are used and sintered together with it become. This can be particularly intensive, sustainable cohesive connections can be realized.
Die Buchse kann dabei als Pressformteil ausgestaltet sein. Ebenso kann die Buchse als Spritzgussteil ausgestaltet sein. Alternativ ist es ebenso möglich, die Buchse als Sinterteil auszubilden. Die unterschiedlichen Herstellungsarten für die Buchse können in Abhängigkeit der erforderlichen Festigkeitswerte, Steifigkeitswerte und Herstellungskosten ausgewählt werden, wobei insbesondere auch die Verbindungstechniken zwischen Buchse und Turbinenrad einerseits sowie zwischen Buchse und Welle andererseits berücksichtigt werden können.The Socket can be designed as a molded part. Likewise the socket be designed as an injection molded part. Alternatively it is it is also possible to form the socket as a sintered part. The different manufacturing methods for the socket depending on the required strength values, Stiffness values and production costs are selected, in particular, the connection techniques between socket and Turbine wheel on the one hand and between socket and shaft on the other can be considered.
Besonders vorteilhaft ist es, sowohl das Turbinenrad als auch die Buchse als Sinterteile auszubilden, wodurch es insbesondere möglich ist, zum einen eine besonders intensive Verbindung zwischen Turbinenrad und Buchse zu realisieren, während zum anderen die Buchse gezielt so gestaltet werden kann, dass die gewünschte feste Verbindung mit der Welle realisierbar ist. Besonders vorteilhaft ist es dabei, die Buchse und das Turbinenrad als MIM-2K-Teil auszugestalten. Dabei steht MIM für „Metal Injection Molding”, während 2K für „zwei Komponenten” steht. Mit anderen Worten, bei der MIM-2K-Technik handelt es sich um eine Spritzgusstechnik zum Herstellen von Sintergrünlingen, die aus zwei Bauteil-Komponenten und/oder aus zwei Werkstoff-Komponenten bestehen. Sie können dabei in einer Spritzgussform mit zwei „Schüssen” geformt werden und bilden dadurch einen einheitlichen Grünling, der durch den Sintervorgang zu einem einstückigen, integralen Bauteil wird. Bei dieser Bauweise wird somit die Buchse in das Turbinenrad integriert. Insoweit bildet die Buchse in diesem Fall kein separates Bauteil bezüglich des Turbinenrads.It is particularly advantageous to construct both the turbine wheel and the bushing as sintered parts, which makes it possible, in particular, to realize a particularly intensive connection between the turbine wheel and bush, while, on the other hand, the bushing can be specifically designed so that the desired solid Connection with the shaft is feasible. It is particularly advantageous to design the bushing and the turbine wheel as MIM-2K-part. MIM stands for "metal injection molding", while 2K stands for "two components". In other words, the MIM-2K technique is an injection molding technique for producing sintered green compacts, which consist of two component components and / or of two material components. They can be molded in an injection mold with two "shots" and thereby form a uniform green body, which is the sintering process to a one-piece, integral component. With this construction, the bush is thus integrated into the turbine wheel. In that regard, the socket in this case does not form a separate component with respect to the turbine wheel.
Die Buchse kann in radialer Richtung mehrschichtig ausgestaltet sein, wobei sie eine zum Stahl der Welle kompatible Innenschicht sowie eine zum Titanaluminid des Turbinenrads kompatible Außenschicht aufweisen kann.The Socket can be configured in the radial direction multi-layered, where it is compatible with the steel of the shaft inner layer as well an outer layer compatible with the titanium aluminide of the turbine wheel can have.
Alternativ kann die Buchse mit radial variierendem oder gradiertem Werkstoff hergestellt sein, wobei sie dann radial innen kompatibel zum Stahl der Welle und radial außen kompatibel zum Titanaluminid des Turbinenrads gestaltet sein kann. Der gradierte Werkstoff, insbesondere ein Dispersionswerkstoff, kann dabei gestuft oder ungestuft in radialer Richtung seine Werkstoffzusammensetzung bzw. seine Werkstoffeigenschaften ändern.alternative can the bush with radially varying or graded material be prepared, in which case they are radially inward compatible with the steel the shaft and radially outside compatible to titanium aluminide the turbine wheel can be designed. The graded material, in particular a dispersion material, can be stepped or ungraded in the radial direction change its material composition or material properties.
Die Kompatibilität zwischen der Buchse und der Welle einerseits und zwischen der Buchse und dem Turbinenrad andererseits kann dabei die Festigkeit der erzielbaren stoffschlüssigen Verbindung und/oder passende Wärmeausdehnungskoeffizienten umfassen. Passende bzw. ähnliche Wärmeausdehnungskoeffizienten zwischen Buchse und Welle einerseits und zwischen Buchse und Turbinenrad andererseits reduzieren thermisch bedingte Spannungen zwischen den miteinander verbundenen Komponenten. Im Betrieb kann das Turbinenrad deutlich höhere Temperaturen erreichen als die Welle, wodurch ein Temperaturgradient zwischen Turbinenrad und Welle entsteht. Um hier Spannungsspitzen aufgrund thermischer Dehnungseffekte zu reduzieren, sind in den Verbindungszonen passende oder ähnliche Wärmeausdehnungskoeffizienten von Vorteil.The Compatibility between the bushing and the shaft on the one hand and between the sleeve and the turbine wheel on the other hand can the strength of the achievable cohesive connection and / or include appropriate thermal expansion coefficients. Suitable or similar coefficients of thermal expansion between Bushing and shaft on the one hand and between bushing and turbine wheel On the other hand, thermally induced stresses reduce between the interconnected components. In operation, the turbine wheel reach much higher temperatures than the wave, creating a Temperature gradient between turbine wheel and shaft arises. Around Here To reduce stress peaks due to thermal expansion effects, are in the connection zones matching or similar coefficients of thermal expansion advantageous.
