Description

Antrieb für die Austragschnecke einer Schneckenzentrifuge Es sind Schneckenzentrifugen bekannt, deren Awstragschnecke durch ein außerhalb der 7_en.trifugentrommel angeordnetes Getriebe mit einer gegenüber der Trommel vor- oder nacheilenden Drehzahl angetrieben wird. Die Getriebe erleiden verhältnismäßig hohe Drehzahlen und bedürfen stets einer sorgfältigen Wartung und Schmierung.Drive for the discharge screw of a screw centrifuge There are Known screw centrifuges, whose extraction screw is driven by an outside of the 7_en.trifuge drum arranged gear with a relative to the drum leading or lagging speed is driven. The gears suffer relatively high speeds and require always careful maintenance and lubrication.

Der Erfindung liegt die Aufgabe zugrunde, ein denkbar einfaches Getriebe zur Erzeugung einer Differenzd-,rehzahl zwischen der Zentrifugentrommel und der Austragschnecke zu schaffen. Sie wird dadurch gelöst, daß die Trommel um eine feststehende Achse sich drehend angeordnet und durch eine an ihr angeordnete Riemenscheibe, ein Zahnrad od. dgl. angetrieben wird. Auf der Achse i.st eine ebenfalls feststehende Schnecke angeordnet, in die ein Schneckenrad greift, das bei der Drehung der Trommel seine Bewegung über zwei bzw. drei Zahnräder einer anderen Schnecke vermittelt, die ihrerseits wieder ein auf dem Körper der Austragsehnecke angeordnetes Schneckenrad antreibt. Somit wird zwischen Trommel und Austragschnecke eine Differenzbe@N-egung erzeugt, und zwar mit Getriebeteilen, die an der Trommel angeordnet sind und sich selbst außerordentlich langsam drehen.The invention is based on the object of a very simple transmission to generate a differential speed between the centrifuge drum and the To create discharge screw. It is solved in that the drum around a fixed Axis arranged to rotate and by a pulley arranged on it Gear or the like. Is driven. On the axis there is also a fixed one Worm arranged, in which a worm wheel engages that when the drum rotates mediates its movement via two or three gears of another worm, in turn a worm wheel arranged on the body of the discharge screw drives. Thus there is a difference in movement between the bowl and the discharge screw generated, with gear parts that are arranged on the drum and turn extremely slowly yourself.

Das Getriebe ist nicht nur zum Antrieb für Schneckenzentrifugen verwendbar, sondern auch überall dort, wo es darauf ankommt, durch einen Antrieb zwei bzw. drei verschiedene Umdrehungsgeschwindigkeiten zu erzeugen.The gear can not only be used to drive screw centrifuges, but also wherever it matters, with one drive two or three to generate different speeds of rotation.

In der Zeichnung ist ein Ausführungsbeispiel sehiematisch dargestellt, wobei Abb. 1 ein lotrechter Schnitt durch die Einrichtung und Abb. 2 eine Seitenansicht ist.In the drawing, an exemplary embodiment is shown schematically, Fig. 1 is a vertical section through the device and Fig. 2 is a side view is.

Mit 1 ist die feststehende Achse bezeichnet, auf der die ebenfalls feststehende Schnecke 2 angeordnet ist. In diese Schnecke greifen Schneckenräder 3 ein, die auf je einer Welle 4 angeordnet sind, auf deren Enden sich Zahnräder 5 befinden, welche in Zahnräder 6 greifen, die auf Wellen 7 angeordnet sind, auf denen auch je eine Schnecke 8 fest verbunden ruht. Die Schnecken 8 greifen in ein Schneckenrad 9, das auf den sich ebenfalls auf der feststehenden Achse 1 drehenden Körper für die Austragschnecke 10 angeordnet ist.1 with the fixed axis is referred to, on which the also fixed screw 2 is arranged. Worm gears engage in this worm 3, which are each arranged on a shaft 4, on the ends of which there are gears 5 are located, which engage in gears 6 which are arranged on shafts 7 on each of which a screw 8 rests firmly connected. The screws 8 intervene Worm gear 9, which also rotates on the fixed axis 1 Body for the discharge screw 10 is arranged.
