Abstract

Die Erfindung betrifft eine zweispindelige Schraubenspindelpumpe in einflutiger Bauweise mit einem Pumpengehäuse, das einen Pumpenabschnitt, einen Lagerabschnitt und einen Getriebeabschnitt mit einem Getrieberaum aufweist, wobei der Lagerabschnitt und der Pumpenabschnitt getrennt voneinander ausgeführt sind. Aufgabe der Erfindung ist es, die vorgenannte Pumpe dahingehend zu verbessern, dass eine einfachere und weniger zeitaufwendige Wartung bzw. Nachjustierung vorgenommen werden kann. Gelöst wird dieses Aufgabe dadurch, die Bohrungen im Befestigungselement so ausgeführt sind, dass das Zahnrad und das Befestigungselement (und damit die Welle) gegeneinander verdrehbar sind, so dass ein Abstand der Flanken, der Förderschrauben (das Flankenspiel der Förderschrauben) einstellbar ist, dass am Getriebeabschnitt des Pumpengehäuses eine Öffnung vorgesehen ist, dass die Öffnung mit einer lösbaren Abdeckung versehen, dass die Öffnung so angeordnet ist, dass die Abdeckung im montierten Zustand der Spindelpumpe lösbar ist, und dass der Getrieberaum zur Einstellung des Flankenspiels der Förderschrauben mit dem dafür notwendigen Werkzeug erreichbar ist.

Figure imgaf001
The invention relates to a single-spindle screw pump in a single-flow design with a pump housing, which has a pump section, a bearing section and a gear section with a gear housing, wherein the bearing section and the pump section are designed separately. The object of the invention is to improve the aforementioned pump to the effect that a simpler and less time-consuming maintenance or readjustment can be made. This object is achieved in that the holes in the fastener are designed so that the gear and the fastener (and thus the shaft) are rotated against each other, so that a distance between the flanks of the conveyor screws (the backlash of the conveyor screws) is adjustable that on Gear portion of the pump housing having an opening is provided that the opening provided with a detachable cover, that the opening is arranged so that the cover in the assembled state of the spindle pump is releasable, and that the gear chamber for adjusting the backlash of the conveyor screws with the necessary tools is reachable.
