BeschreibungDescription
Exzenterschneckenpumpen üblicher Bauart erfordern normalerweise zum Auswechseln des Rotors einen erhöhten Montageaufwand und eine Zugänglichkeit der Verbindungsteile Rotor/Antriebswelle bzw. Rotor/Vorförderschnecke.Diese leichte Zugänglichkeit ist jedoch bei fest installierten Exzenterschnecken-Rachenpumpen vielfach nicht gewährleistet und macht meist einen Ausbau der gesamten Exzenterschneckenpumpe notwendig.Eccentric screw pumps of the usual design normally require increased assembly effort and accessibility of the connecting parts rotor/drive shaft or rotor/pre-feed screw in order to replace the rotor. However, this easy accessibility is often not guaranteed with permanently installed eccentric screw throat pumps and usually makes it necessary to remove the entire eccentric screw pump.
Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, daß insbesondere beim Einsatz von Exzenterschnecken-Rachenpumpen unter Lagerbehältern (Silos, Tanks etc.) eine Demontage der gesamten Pumpe nicht möglich ist und die Betriebsunterbrechungszeit für Wartungs- bzw. Reparaturarbeiten minimiert werden muß.The invention specified in claim 1 is based on the problem that, in particular when using eccentric screw pumps under storage containers (silos, tanks, etc.), it is not possible to dismantle the entire pump and the downtime for maintenance or repair work must be minimized.
Dieses Problem wird mit den im Schutzanspruch aufgeführten Merkmalen gelöst.This problem is solved with the features listed in the protection claim.
Mit der Erfindung wird erreicht, daß ein rascher Wechsel des Rotors durchgeführt werden kann, ohne daß die Zugänglichkeit der Anschlußteile rachenseitig oder saugseitig erforderlich ist.The invention makes it possible to quickly change the rotor without requiring access to the connecting parts on the throat side or suction side.
Eine vorteilhafte Ausgestaltung der Erfindung ist im Schutzanspruch 2 beschrieben, da der Steckzapfen (A) zur verbesserten Einführbarkeit in die Steckhülse (B) am Kopfende konisch angeschrägt ist.An advantageous embodiment of the invention is described in claim 2, since the plug pin (A) is conically bevelled at the head end for improved insertion into the plug sleeve (B).
Ein weiterer Vorteil der Erfindung ist die Herstellung des Kraftschlusses über eine Paßfederverbindung. Geeignet sind jedoch auch anderweitige, unter den jeweiligen Montagebedingungen lösbare Verbindungsarten (z.B . Keilverbindung etc.).A further advantage of the invention is the creation of the frictional connection via a keyway connection. However, other types of connection that can be released under the respective assembly conditions (e.g. wedge connection, etc.) are also suitable.

In den Figuren 1 bis 4 ist jeweils der Steckzapfen und die Steckhülse in verschiedenen Ansichten und Schnitten dargestellt.Figures 1 to 4 show the plug pin and the plug sleeve in different views and sections.
Figur 1 und 2 zeigt den zylinderförmigen, am Kopfende konisch angeschrägten Steckzapfen mit Fußplatte und durchmesserreduziertem Mittelstück (zur besseren Montierbarkeit der Schrauben) sowie Paßfedernut nach Schutzanspruch 1.Figures 1 and 2 show the cylindrical plug pin, which is tapered at the head end, with a base plate and a reduced-diameter middle piece (for easier installation of the screws) as well as a feather keyway according to claim 1.
Figur 3 und 4 zeigen die Steckhülse nach Schutzanspruch 2.Figures 3 and 4 show the plug sleeve according to claim 2.
Figur 5 zeigt einen Zusammenbau, wie er üblicherweise bei Exzenterschneckenpumpen vorgenommen wird. Daraufist der Rotor (C), Steckzapfen ((A), Steckhülse (B), sowie die Vorförderschnecke (D) zu erkennen.Figure 5 shows an assembly as is usually done with eccentric screw pumps. The rotor (C), plug pin (A), plug sleeve (B) and the pre-feed screw (D) can be seen.
