Description
Die Erfindung betrifft ein Laufrad nach dem Oberbegriff des ersten Anspruchs.The The invention relates to an impeller according to the preamble of the first claim.
Bei
Brennkraftmaschinen werden Laufräder beispielsweise
als Radiallüfter
oder als Verdichterrad für
einen Abgasturbolader verwendet. Problematisch bei diesen Laufrädern ist
die Geräuschentwicklung, die
häufig
als unangenehm empfunden wird. Eine gängige Maßnahme zur Geräuschreduktion
besteht darin, das Laufrad mit Voll- und Splitterschaufeln zu bestücken. Eine
derartige Ausführung

Die der Erfindung zu Grunde liegende Aufgabe wird darin gesehen, die Geräuschemission eines Laufrades weiter zu reduzieren.The The object underlying the invention is seen therein, the noise an impeller further reduce.
Die Aufgabe wird durch die Merkmale des ersten Anspruchs gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen dargestellt.The Task is solved by the features of the first claim. advantageous Embodiments are shown in the subclaims.
Vorgeschlagen wird bei einem gattungsgemäßen Laufrad, dass die Vollschaufeln und Splitterschaufeln in unterschiedlichem Winkelabstand und unterschiedlicher sowie rotationsasymmetrischer Reihenfolge angeordnet sind. Hierdurch wird der Störgeräusch-Pegel deutlich reduziert. Die Schallleistung verteilt sich durch die konstruktiven Maßnahmen auf mehrere Einzeltöne, deren Intensität entsprechend niedriger ausfällt. Ein weiterer Vorteil besteht darin, dass der Wirkungsgrad und die Leistungsaufnahme des Laufrades nahezu konstant bleiben.proposed is in a generic impeller, that the full blades and splitter blades in different Angular distance and different and rotationally asymmetric order are arranged. As a result, the noise level is significantly reduced. The sound power distributed through the constructive measures on several single tones whose intensity correspondingly lower fails. Another advantage is that the efficiency and the Power consumption of the impeller remain almost constant.
Durch die Verwendung eines alternativen Werkstoffes, beispielsweise Aluminium, wird das Massenträgheits-Moment des Laufrades abgesenkt. Für die Praxis bedeutet dies, dass z. B. bei einem Laufrad mit einem Durchmesser 670 mm, ein deutlich besseres Ansprechverhalten erzielt wird.By the use of an alternative material, for example aluminum, becomes the moment of inertia lowered the impeller. For In practice, this means that z. B. in an impeller with a Diameter 670 mm, achieved a much better response becomes.
Durch eine entsprechende Ausformung der Rückseite des Laufrades ist es möglich, dass eine Kupplung und ein Lager integriert werden können. Hierdurch wird der Vorteil erzielt, dass bei gleichbleibender Bauhöhe die Packungsdichte vergrößert wird. Als Konsequenz ergibt sich somit eine montagefreundlichere Lösung.By a corresponding shape of the back of the impeller is possible, that a coupling and a bearing can be integrated. hereby the advantage is achieved that at the same height the packing density is enlarged. As a consequence, this results in a more user-friendly solution.
