Abstract

Es wird ein Strömungsmaschinenrad (10) insbesondere für ein Tauchrührwerk oder für eine Abwasser-, Schlamm-, Schmutzwasser- oder Fäkalienpumpe oder für eine Rezirkulationspumpe mit einer Wellennabe (12) beschrieben, die ein Naben-Innenteil (14) und ein Naben-Außenteil (16) aufweist, zwischen welchen ein Naben-Dämpfungselement (26) aus einem elastischen Material vorgesehen ist. Vom Naben-Außenteil (16) stehen Flügelblätter (22) weg. Zwischen dem Naben-Außenteil (16) und dem jeweiligen Flügelblatt (22) sind Flügelblatt-Dämpfungselemente (40) aus elastischem Material vorgesehen. Desgleichen ist es möglich, daß das Strömungsmaschinenrad (10) entweder nur ein Naben-Dämpfungselement (26) oder nur Flügelblatt-Dämpfungselemente (40) aufweist, um durch unkontrollierte hydraulische Bedingungen bzw. Eigenschaften und Anströmungen verursachte Vibrationen bzw. Beschädigungen des Strömungsmaschinenrades bzw. des damit verbundenen Antriebsmotors, des Getriebes, der Halterungen hierfür usw. (10) zumindest zu reduzieren oder zu vermeiden.

Figure 00000001
A turbomachine wheel (10) is described in particular for a submersible mixer or for a sewage, sludge, dirty water or faecal pump or for a recirculation pump with a shaft hub (12), which has an inner hub part (14) and an outer hub part ( 16), between which a hub damping element (26) made of an elastic material is provided. Wing blades (22) protrude from the outer hub part (16). Wing-leaf damping elements (40) made of elastic material are provided between the outer hub part (16) and the respective wing blade (22). Likewise, it is possible for the turbomachine wheel (10) to have either only one hub damping element (26) or only wing blade damping elements (40) in order to prevent vibrations or damage to the turbomachine wheel or the airframe caused by uncontrolled hydraulic conditions or properties and inflows associated drive motor, the transmission, the brackets therefor, etc. (10) at least to reduce or avoid.
