Die Aufgabe der vorliegenden Erfindung ist es, eine aus dem Stand der Technik bekannte Vorrichtung in der Art weiterzubilden, dass die erforderlichen Aufwendungen zur Herstellung der Kontaktflächen und damit die Herstellkosten reduziert werden und dabei die Betriebssicherheit und die Zuverlässigkeit der Vorrichtung erhöht werden.The Object of the present invention is one of the prior Technique known device in the way that the required expenses for the production of the contact surfaces and thus the manufacturing costs are reduced and thereby the operational safety and increases the reliability of the device become.
Diese Aufgabe wird durch eine Vorrichtung mit den Merkmalen des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen genannt.These The object is achieved by a device having the features of the claim 1 solved. Advantageous embodiments are in the subclaims called.
Bei einer Vorrichtung der Eingangs beschriebenen Art ist es erfindungsgemäß vorgesehen, dass eine Kontaktfläche zwischen dem Rad und dem Widerlager und/oder zwischen dem Rad und dem Befestigungselement derart ausgeführt ist, dass das Rad aufgrund von an der Kontaktfläche auftretender Reibung an einem radialen Verschieben gehindert ist. Der Kern der vorliegenden Erfindung liegt darin, die Kontaktfläche derart zu gestalten, dass schon geringe radiale Bewegungen des Rades relativ zur Drehachse der Welle durch die an der Kontaktfläche auftretende Reibung unterbunden werden. Als Kontaktfläche im Sinne dieser Erfindung wird der Bereich bezeichnet, in dem sich zwei Bauelemente berühren.at a device of the type described in the introduction, it is provided according to the invention that a contact surface between the wheel and the abutment and / or executed between the wheel and the fastener is that the wheel due to occurring at the contact surface friction is prevented from radial displacement. The core of the present Invention is to design the contact surface in such a way that even small radial movements of the wheel relative to the axis of rotation the shaft by the friction occurring at the contact surface be prevented. As contact surface in the sense of this invention is the area in which two components touch.
Neben der Eigenschaft der Kontaktfläche, eine Verschiebung des Rades gegenüber der Welle wirkungsvoll zu unterbinden, weist eine derart gestaltete Kontaktfläche zusätzlich die Eigenschaft auf, das Rad durch die an der Kontaktfläche auftretende Reibung an einer Verdrehung relativ zu dem Widerlager und/oder dem Befestigungselement zu hindern.Next the property of the contact surface, a displacement of the To effectively prevent the wheel from the shaft has such a shaped contact surface in addition the property on, the wheel through at the contact surface occurring friction on a rotation relative to the abutment and / or to prevent the fastener.
Ein bevorzugter Einsatz für die vorliegende Erfindung ist im Bereich schnell laufender Turbomaschinen denkbar. Das Rad kann hierbei ein Verdichter- oder Turbinenrad sein. Insbesondere kann diese Technologie in Abgasturboladern bei der Verbindung von einem Verdichterrad mit einer Turbinenwelle zum Einsatz kommen. Denkbar ist aber auch der Einsatz in anderen Bereichen, bei denen durch das Auftreten von radial wirkenden Kräften Probleme mit Bauteilverschiebungen entstehen können, beispielsweise im Turbinenbau.One preferred use for the present invention is in Range of high-speed turbomachines conceivable. The wheel can do this be a compressor or turbine wheel. In particular, this technology can in exhaust gas turbochargers in the connection of a compressor with a turbine shaft are used. But it is also conceivable Use in other areas where by the appearance of Radially acting forces Problems with component displacements can arise, for example in turbine construction.
Sollte es aufgrund der technischen Erfordernisse vorteilhaft sein, so kann an der Kontaktfläche ein Zwischenelement mit Reibkontaktflächen eingefügt sein.Should it may be advantageous due to the technical requirements, so may at the contact surface an intermediate element with Reibkontaktflächen be inserted.
Das Zwischenelement wird vorzugsweise als Zwischenblech ausgeführt, da dünnes Metall als Basis für ein solches Zwischenelement gute Voraussetzungen hinsichtlich Formstabilität, Druck- bzw. Zug- und Scherfestigkeit aufweist. Ferner eignet es sich gut zum Beschichten mit Zusatzwerkstoffen an den Oberflächen.The Intermediate element is preferably designed as an intermediate plate, because thin metal as the basis for such an intermediate element good conditions with regard to dimensional stability, pressure or tensile and shear strength has. Furthermore, it is good for coating with additional materials on the surfaces.
Durch die Gestaltung des Rades mit Hilfe eines Ur- oder Umformverfahrens ergibt sich neben der Möglichkeit einer freieren Gestaltung der Reibkontaktfläche die Option, die Rauhigkeit der Kontaktflächen schon während des Formgebungsprozesses in das Rad zu integrieren. Dies geschieht beispielsweise dadurch, dass die Rauhigkeitsstruktur in einer Urform oder einem Umformwerkzeug ausgestaltet wird und sich dann beim Urform- oder Pressvorgang auf die Kontaktflächen des entsprechenden Bauteils überträgt.By the design of the wheel by means of a master or forming process results in addition to the possibility of a freer design the frictional contact surface option, the roughness of the contact surfaces already integrated into the wheel during the molding process. This happens, for example, in that the roughness structure is designed in a master mold or a forming tool and Then during the forming or pressing process on the contact surfaces of the corresponding component transmits.
Eine Möglichkeit das Rad in der vorstehend beschriebenen Art zu gestalten, ist das Rad als Sinterbauteil zu auszuführen.A Possibility of the wheel in the manner described above To design, the wheel is designed as a sintered component.
Um die Kontaktflächen mit einer erforderlichen Rauhigkeit zu versehen, kann es sinnvoll sein, diese mit entsprechendem Zusatzmaterial zu beschichten. Diese Beschichtung kann während oder nach dem Herstellprozess an den entsprechenden Oberflächen aufgebracht werden.Around the contact surfaces with a required roughness to provide, it may be useful, this with appropriate additional material to coat. This coating may be during or after the manufacturing process applied to the corresponding surfaces become.
Die Beschichtung enthält Bestandteile, die gegenüber dem Grundmaterial des Zwischenelementes eine erhöhte Härte aufweisen. Zum Einsatz kommen hier vorzugsweise kohlenstoffhaltige Materialien, beispielsweise Diamant oder Metallkarbidverbindungen. Weiterhin ist aber auch der Einsatz von Aluminiumoxiden, sogenannten Korundverbindungen, oder ähnlichem vorstellbar. Die Auswahl der passenden Materialen kann sich nach den Anforderungen an die Baugruppe richten. Hier sind beispielsweise mechanische und oder thermische Beanspruchungen sowie weitere Umgebungseinflüsse zu berücksichtigen.The Coating contains ingredients that are opposite the base material of the intermediate element increased hardness exhibit. For use here are preferably carbonaceous Materials, such as diamond or metal carbide compounds. Furthermore, however, is the use of aluminum oxides, so-called Corundum compounds, or the like conceivable. The selection the appropriate materials can vary according to the requirements of the Set up the assembly. Here are, for example, mechanical and or thermal stresses and other environmental influences to take into account.
Um das Rad auf der Welle mit Hilfe eines Befestigungselementes zu befestigen, kommt vorzugsweise eine Mutter zum Einsatz, die auf ein an der Welle angeordnetes Gewinde aufschraubbar ist. Diese Ausgestaltung ermöglicht es, die für eine definierte Klemmung erforderlichen Kräfte präzise und reproduzierbar aufzubringen. Je nach Anwendung oder Belastungsfall ist als Befestigungselement auch der Einsatz federbelasteter Klemmscheiben oder ähnlichem denkbar mit denen die für den Betrieb der Vorrichtung erforderliche Klemmkräfte auf das Rad aufbringbar sind.Around to fix the wheel on the shaft by means of a fastener, Preferably, a nut is used, which is a on the shaft arranged thread can be screwed. This configuration allows it, the forces required for a defined clamping to apply precisely and reproducibly. Depending on the application or load case is also the use as a fastener spring-loaded clamping disks or the like conceivable with those required for the operation of the device Clamping forces are applied to the wheel.
