FlügelradImpeller
Gegenstand der Neuerung ist ein Flügelrad aus elastischem Werkstoff, insbesondere für Kreiselpumpen mit kleiner Leistung wie Laugenpumpen od. dgl. Letztere werden im allgemeinen durch Kegelstifte auf der Antriebswelle befestigt, um damit gleichzeitig das notwendige Drehmoment mit Sicherheit übertragen zu können. Bestehen derartige Flügelräder jedoch aus Kunststoff oder aus einer Gummi-Metallverbindung, so ergeben sich erhebliche Schwierigkeiten, wenn man die Aufnahmebohrung für den Kegelstift bei der Formgebung des Flügelrades mit herstellen möchte.The object of the innovation is an impeller made of elastic material, especially for centrifugal pumps with low power such as lye pumps or the like. The latter are generally by means of tapered pins on the drive shaft attached in order to be able to transmit the necessary torque with certainty at the same time. Such impellers exist, however Made of plastic or a rubber-metal compound, there are considerable difficulties when you open the mounting hole for the Want to manufacture taper pin when shaping the impeller.
Aufgabe der Neuerung istj,,es, den Innenumfang der Flügelradbüchse derart zu gestalten, daß das Flügelrad mit einer Formgebung sowohl in radialer als auch in axialer Richtung fixierbar ist.The task of the innovation is to adjust the inner circumference of the impeller liner in such a way to design that the impeller can be fixed with a shape both in the radial and in the axial direction.
Es gibt zwar bereits Flügelräder aus elastischem Kunststoff, od. dgl. für geringe axiale Belastung, deren Büchse aus dem gleichen elastischen Werkstoff besteht wie das Rad .und auf einer Stirnseite einen nach innen gerichteten Bund aufweist, der in eine Ausnehmung der zugeordneten Welle einrastet. Diese Laufräder sind jedoch nicht geeignet, ein Drehmoment von der Welle auf das Rad zu übertragen, da das Rad frei be·» weglich auf der Welle sitzt.There are already vane wheels made of elastic plastic, od. The like. For low axial load, the bushing is made of the same elastic material as the wheel has directed federal government in a recess of the associated Shaft engages. However, these impellers are not capable of torque to be transferred from the shaft to the wheel, since the wheel is freely sits movably on the shaft.

Gemäß der Neuerung wird vorgeschlagen, die Wellenaufnehmebohrung (Büchse) des Flügelrades mit einem ganz oder teilweise umlaufenden Gummiwulst zu versehen, der in an sich bekannter Weise in die Ausnehmung der Welle hineingesprengt werden kann, um so eine axiale Befestigung des Rades zu sichern; darüber hinaus ist der Innenumfang der Ausnahmebohrung und der Außenumfang der Welle mindestens teilweise von der Kreisform, abweichend ausgebildet, wodurch gleichzeitig eine sichere Drehmomentübertragung entsteht.According to the innovation, it is proposed that the shaft receiving bore (Bushing) of the impeller with a wholly or partially revolving To provide rubber bead, which can be blown into the recess of the shaft in a manner known per se, so as to provide an axial attachment to secure the bike; in addition, the inner circumference of the recess bore and the outer circumference of the shaft are at least partially of the circular shape, designed differently, whereby at the same time a safe torque transmission is created.
In einfacher Weise kann die Drehmomentübertragung dadurch gebildet werden, daß die Antriebswelle eine Abflachung aufweist, die negativ auch in der Bohrung des Flügelrades vorhanden ist. Zur Verstärkung der Drehmomentübertragung kann auf der Rückseite des Rades im- Bereiche der Buchsenbohfung eine Verstärkung aus Hartstoff vorgesehen werden, die vorzugsweise mit dem elastischen Rad ζ, Β. durch Vulkanisation verbunden sein kann.The torque transmission can thereby be formed in a simple manner be that the drive shaft has a flat surface that is also negative in the bore of the impeller. For reinforcement For torque transmission, a reinforcement made of hard material can be provided on the back of the wheel in the area of the socket hole are, preferably with the elastic wheel ζ, Β. by vulcanization can be connected.
In der Zeichnung ist die Neuerung an einem Ausführungsbeispiel dargestellt, und zwar zeigen In the drawing, the innovation is shown in an embodiment, namely show
Fig. 1 und 2 das Laufrad in Draufsicht un im Schnitt und Fig. 3 und 4 die Welle.Fig. 1 and 2 the impeller in plan view and in section 3 and 4 the shaft.
Das Laufrad 1 weist an seinem Innenumfang einen Wulst 2 auf (Fig. und 2), der in die Ausnehmung 3 der Welle 4 (Fig. 3 und 4) nach derThe impeller 1 has a bead 2 on its inner circumference (Fig. and 2), which is in the recess 3 of the shaft 4 (Fig. 3 and 4) after
Montage einrastet. Durch die Abflachung 5 am Flügelrad 1 und Abflachung 6 an der Welle 4 besteht die Möglichkeit der einwandfreien Drehmomentübertragung. Auf der Rückseite ist das Flügelrad durch eine Hartstoffs cheibe 7 verstärkt.Assembly snaps into place. Through the flat 5 on the impeller 1 and flat 6 on the shaft 4 there is the possibility of perfect torque transmission. The impeller is through on the back a hard material disk 7 reinforced.
