Description

Laufradbefestigung auf der Welle von Kreiselmaschinen, z. B. Kreiselpumpen Die Erfindung betrifft eine Laufradbefestigung auf der Welle von Kreiselmaschinen, z. B. Kreiselpumpen. Sie besteht darin, daß am Wellenende eine trapezförmige Nut zur Aufnahme von kugel- oder tonnenförmigen oder beliebig anders geformten festen Abstützkörpern vorgesehen ist, die an den zur Wellenachse schräg verlaufenden Stirnseiten des Nabenbundes und einer Schraubenhülse anliegen, wobei die Anliegeflächen für die Abstützkörper so zur Wellenachse geneigt sind, daß sowohl axial als auch radial gerichtete Kraftkomponenten der Abstützkräfte entstehen.Impeller mounting on the shaft of centrifugal machines, e.g. B. centrifugal pumps The invention relates to an impeller attachment on the shaft of centrifugal machines, z. B. centrifugal pumps. It consists in a trapezoidal groove at the end of the shaft For holding spherical or barrel-shaped or any other shaped solid Support bodies is provided on the end faces which run obliquely to the shaft axis of the hub collar and a screw sleeve, the contact surfaces for the support bodies are inclined to the shaft axis so that both axially and radially directed force components of the support forces arise.

Durch die Erfindung wird eine toleranzfreie Laufradbefestigung in den drei Freiheitsgraden gewährleistet. Ferner sind die Toleranzmaße der einzelnen Befestigungsmittel auf die starre Befestigung des Laufrades ohne Einfluß.The invention provides a tolerance-free impeller attachment in the three degrees of freedom guaranteed. Furthermore, the tolerance dimensions of the individual Fastening means on the rigid attachment of the impeller without influence.

Es sind Laufradbefestigungen bekannt, bei denen mit Hilfe eines in einer Wellennut eingelassenen geteilten Ringes eine Befestigung mit dem Laufrad über eine Schraubenhülse hergestellt wird. Dieser geteilte Ring läßt sich jedoch mit der Welle nicht starr befestigen, weshalb auch eine feste Verbindung des Laufrades mit der Welle nicht möglich ist. Die Qualität der Laufradbefestigung wird deshalb bei Verwendung dieser bekannten Elemente immer von deren Toleranzmaßen bestimmt, im Gegensatz zur vorliegenden Erfindung, wo die starre Befestigung des Laufrades vollkommen unabhängig von den Toleranzmaßen der einzelnen Befestigungselemente ist.There are impeller mountings known in which with the help of an in a split ring embedded in a shaft groove for attachment to the impeller is made via a screw sleeve. However, this split ring can Do not attach rigidly to the shaft, which is why the impeller is firmly connected with the wave is not possible. The quality of the wheel attachment is therefore when using these known elements always determined by their tolerance dimensions, in contrast to the present invention, where the rigid attachment of the impeller is completely independent of the tolerance dimensions of the individual fastening elements.

Ein Ausführungsbeispiel vorliegender Erfindung ist in der Zeichnung dargestellt.An embodiment of the present invention is shown in the drawing shown.

Zur axialen Abstützung der Laufradnabe 3 sind tonnenförmige Stahlkörper 12 in die trapezförmige Ringnut 13 eingesetzt. Zur Übertragung des Drehmomentes auf die Welle dient die Paßfeder 2. Durch die Abschrägung der Stirnseite 10 von Nabe 3 und der Stirnseite 11 von Schraubenhülse 4 wird die Laufradnabe genau zur Welle 1 zentriert und zugleich ohne jegliche Freiheitsgrade fest mit ihr verbunden.For the axial support of the impeller hub 3, barrel-shaped steel bodies 12 are inserted into the trapezoidal annular groove 13. The parallel key 2 is used to transmit the torque to the shaft. The bevel of the end face 10 of the hub 3 and the end face 11 of the screw sleeve 4 center the impeller hub exactly with respect to the shaft 1 and at the same time firmly connect it to it without any degree of freedom.
