Abstract
Einrichtung zur Verdrehsicherung eines Stators einer Exzenterschneckenpumpe, mit einem einen metallischen Mantel mit einer Umhüllung, ausgeführt vorzugsweise als Kunststofffolie, aufweisenden Statorkörper mit einer Halterung mit einer Ausnehmung und einem in dieser radial abstehend angeordneten, mit einem Anschlag korrespondierenden Zapfen, wobei die Oberfläche des Statorkörpers wendelförmig oder eben ausgestaltet ist, dadurch gekennzeichnet, dass ein Endabschnitt (7) des Zapfens (4) in die Ausnehmung (6) einsteckbar ist.Facility for preventing rotation of a stator of an eccentric screw pump, with a metallic shell with a sheath, preferably carried out as a plastic film, having stator with a holder with a recess and arranged in this radially projecting, with a stop corresponding pin, the surface of the stator helically or just designed, characterized in that an end portion (7) of the pin (4) in the recess (6) can be inserted.
Description
Die Erfindung betrifft eine Einrichtung zur Verdrehsicherung eines ummantelten Stators mit einem Statorkörper einer Exzenterschneckenpumpe, wobei an dem Statorkörper ein Zapfen angeordnet ist, der mit einem am Gehäuse der Pumpenanordnung vorgesehenen Anschlag korrespondiert, um während des Betriebs einer entsprechenden Pumpenanordnung den Stator gegen ein axiales Verdrehen zu sichern.The The invention relates to a device for preventing rotation of a jacketed Stator with a stator body an eccentric screw, wherein on the stator body a Pin is arranged, which provided with a housing on the pump assembly Stop corresponds to during the operation of a corresponding pump arrangement against the stator to secure an axial twisting.
Aus
dem
Bei dieser Lösung besteht ein Nachteil darin, dass ein vergleichsweise hoher Aufwand zur Herstellung entsprechender Gewindeteile und darüber hinaus Aufwand zum Einschrauben des Zapfens in das Gewinde des erwähnten Elements erforderlich ist.at this solution There is a disadvantage in that a comparatively high effort for producing corresponding threaded parts and beyond Effort for screwing the pin in the thread of the mentioned element is required.
Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung der vorgenannten Art zu schaffen, die es ermöglicht, den Herstellungs- und Montageaufwand zu verringern.Of the Invention is based on the object, a device of the aforementioned To create kind that makes it possible to reduce the manufacturing and assembly costs.
Die Aufgabe wird gemäß der Erfindung mit den Merkmalen nach dem Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen beschrieben.The Task is according to the invention solved with the features of claim 1. Advantageous embodiments The invention are described in the subclaims.
Mit der Erfindung wird erreicht, dass nach der Ummantelung des Stators der gegen sein Verdrehen erforderliche Zapfen in einfacher Weise durch die Ummantelung hindurch in die Ausnehmung der Halterung am Mantel gesteckt und mit geringfügigem Kraftaufwand, beispielsweise durch Einschlagen, in derselben Bewegungsrichtung in die Ausnehmung haltbar eingepresst werden kann.With The invention is achieved in that after the jacket of the stator the required against twisting pin in a simple manner through the sheath into the recess of the holder on Coat put in place and with little effort, for example, by wrapping, in the same direction of movement can be pressed durable in the recess.
Dadurch werden der Aufwand für die Herstellung der jeweiligen Gewinde und der Zeitaufwand für das dazu erforderliche Einschrauben des Zapfens in die Halterung vermieden. Das nunmehrige gewindelose Einbringen des Zapfens ist dage gen vergleichsweise schnell zu erledigen.Thereby be the effort for the preparation of the respective thread and the time required for this required screwing the pin in the holder avoided. The now threadless insertion of the pin is comparatively Dage conditions to do quickly.
Außerdem wird bei einer lediglich axialen Bewegungsrichtung bei der Montage des Zapfens gegenüber der Ausnehmung die üblicherweise auf den Stator aufgeschrumpfte Ummantelung nicht verdreht oder beschädigt, wohingegen bei der Lösung nach dem Stand der Technik auf Grund der Drehbewegung des Zapfens im Bereich der Gewinde eine Beschädigung der eng anliegenden Ummantelung (Kunststofffolie) möglich ist.In addition, will in a merely axial movement direction during assembly of the Pin opposite the recess usually on the stator shrunk jacket not twisted or damaged, whereas at the solution according to the prior art due to the rotational movement of the pin in the area of the thread damage the close fitting Sheathing (plastic film) possible is.
