Abstract
Description
Die vorliegende Erfindung betrifft eine Radial-Lüfterrad-Anordnung, bestehend aus einer kreisförmigen Bodenscheibe und einer kreisförmigen Deckscheibe mit einer mittigen Einströmöffnung sowie zwischen der Bodenscheibe und der Deckscheibe verlaufenden Radschaufeln, wobei auf mindestens einer der beiden Scheiben im Scheibenrandbereich mindestens ein Ausgleichgewicht befestigt ist.The present invention relates to a radial impeller assembly consisting of a circular bottom plate and a circular cover plate with a central inlet opening and running between the bottom plate and the cover disc vanes, wherein at least one balance weight is fixed on at least one of the two discs in the disc edge region.
Eine derartige Anordnung ist beispielsweise aus der
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, ausgehend von einer Radial-Lüfterrad-Anordnung der eingangs beschriebenen Art, diese derart zu verbessern, dass einerseits eine einfache Montage der Ausgleichgewichte möglich ist und andererseits ein möglichst geringer Einfluss der Ausgleichgewichte auf das Strömungsverhalten vorhanden ist, dass keine zusätzlichen Strömungsgeräusche durch die Ausgleichgewichte verursacht werden.The present invention is based on the object, starting from a radial impeller arrangement of the type described above, to improve them in such a way that, on the one hand, a simple assembly of the balance weights is possible and, on the other hand, the lowest possible influence of the balance weights on the flow behavior is present, that no additional flow noise caused by the balance weights.
Erfindungsgemäß wird dies dadurch erreicht, dass im Zwischenraum zwischen den Radschaufeln im äußeren Randbereich der Deckscheibe und/oder der Bodenscheibe partiell zumindest einseitig in der Scheibenoberfläche taschenförmige Vertiefungen durch Verringerung der Scheibendicke ausgebildet sind, und im Bereich mindestens einer der taschenförmigen Vertiefungen zumindest ein Ausgleichgewicht oder mehrere Ausgleichgewichte befestigt ist/sind. Hierdurch sind die Ausgleichgewichte zumindest teilweise in der jeweiligen Scheibe versenkt befestigt, wodurch Strömungsgeräusche reduziert werden. Durch die erfindungsgemäße Lösung ist eine genaue Winkellage der Ausgleichgewichte möglich. Zudem wird eine gute Zugänglichkeit beim Stecken der Ausgleichgewichte erreicht.According to the invention, this is achieved in that pocket-shaped recesses are formed in the space between the paddles in the outer edge region of the cover plate and / or the bottom plate partially at least on one side in the disc surface by reducing the thickness of the disc, and at least in the area one of the pocket-shaped depressions is at least one balance weight or more balance weights attached / are. As a result, the balance weights are at least partially sunk in the respective disc, whereby flow noise can be reduced. The inventive solution a precise angular position of the balance weights is possible. In addition, good accessibility when inserting the balance weights is achieved.
Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen sowie in den Nebenansprüchen enthalten. Durch die erfindungsgemäße Ausgestaltung wird ein sicherer Halt der Ausgleichgewichte durch eine konstante Materialdicke im Bereich der taschenförmigen Vertiefungen bzw. im äußeren Randbereich der Deck- und/oder Bodenscheibe möglich. Zudem können bereits vorhandene Ausgleichgewichte verwendet werden. Auf Grund der vertieften bzw. abgeschirmten Anordnung der klammerartigen Ausgleichgewichte und insbesondere einer speziellen Verdickung der Scheibenwandung wird eine derartige Strömungsführung der strömenden Luft bewirkt, dass die Luftströmung im Wesentlichen oberhalb der aufgesteckten Ausgleichgewichte stattfindet.Further advantageous embodiments of the invention are contained in the subclaims and in the additional claims. Due to the configuration according to the invention, a secure hold of the balance weights by a constant material thickness in the pocket-shaped depressions or in the outer edge region of the cover and / or bottom plate is possible. In addition, existing balance weights can be used. Due to the recessed or shielded arrangement of the clamp-like counterweights and in particular a special thickening of the disk wall such a flow guidance of the flowing air is effected, that the air flow takes place substantially above the attached balance weights.
