Description
Einrichtung zur Änderung der Fördermenge von Zahnradpumpen durch achsiale Verstellung der Zahntrommeln gegeneinander. Es sind Einrichtungen zur Änderung der Fördermenge von Zahnradpumpen bei gleichbleibender Umdrehungszahl bekannt, bei denen die fördernden Zahnräder gegeneinander in der Achsrichtung verschoben werden und an Stelle des verschobenen Zahnrades ein seinen Raum dicht ausfüllender Körper tritt.Device for changing the delivery rate of gear pumps through axial Adjustment of the toothed drums against each other. There are bodies for changing the Flow rate of gear pumps at a constant number of revolutions known, in which the conveying gears are shifted against each other in the axial direction and instead of the shifted gear, there is a body that tightly fills its space.
Die vorliegende Erfindung betrifft eine Ausführungsart einer solchen Einrichtung und besteht darin, daß die Zahnräder samt den sie umgebenden Geräusehälften gegeneinander verschoben werden.The present invention relates to an embodiment of such Device and consists in the fact that the gears together with the surrounding halves of the noise are shifted against each other.
Diese Einrichtung hat den bekannten Einrichtungen gegenüber den Vorteil, daß sie weniger Bestandteile erfordert, daß sich hierdurch der Aufbau der Zahnradpumpe, die Herstellung sowie das Gewicht derselben einfacher bzw. niedriger gestalten und die Dichtigkeit der Zahnräder in den entsprechenden Hohlräumen des Gehäuses erhöht wird.This facility has the advantage over the known facilities, that it requires fewer components, that this improves the structure of the gear pump, make the production and the weight of the same simpler or lower and increases the tightness of the gears in the corresponding cavities of the housing will.
Abb. i stellt den Gegenstand der Erfindung im Längsschnitt, Abb. 2 im Querschnitt und Abb. 3 im Längsschnitt, für geringere Fördermenge verstellt, dar.Fig. I shows the subject matter of the invention in longitudinal section, Fig. 2 in cross section and Fig. 3 in longitudinal section, adjusted for lower delivery rate, represent.
Auf die durch die Antriebsmaschine in Drehung zu setzenden Wellen i und 2 (Abb. i und 2) sind die in ihrer vollen Breite im Eingriff stehenden Zahnradtrommeln 3 und 4 fest aufgesetzt und werden durch das zwischen den beiden Zahnrädtrommeln geteilte Gehäuse 5, 6 dicht umschlossen, so daß sie, wenn sie in Drehung gesetzt werden, wie eine normale Zahnradpumpe wirken, und die geförderte Flüssigkeit durch die Anschlußstutzen 7 und 8 des geteilten Gehäuses 5, 6 strömt.On the shafts to be set in rotation by the drive machine i and 2 (Fig. i and 2) are the full width meshed gear drums 3 and 4 firmly attached and are through the between the two gear drums split housing 5, 6 tightly enclosed so that when they are set in rotation will act like a normal gear pump, and the pumped liquid through the connecting pieces 7 and 8 of the divided housing 5, 6 flows.
Beide Gehäusehälften 5, 6 haben je eine auf der in der Achsrichtung entgegengesetzten Seite angebrachte lappenförmige Verlängerung 9 und io, von welcher jede die andere Gehäusehälfte samt der darin liegenden Zahnradtrommel dicht abdeckt, falls die eine Gehäusehälfte, im dargestellten Falle die untere 6, in der Richtung des Pfeiles ii gegen die andere Gehäusehälfte 5 auf irgendeine Weise verschoben wird (Abb. 3).Both housing halves 5, 6 each have a flap-shaped extension 9 and io attached to the opposite side in the axial direction, each of which tightly covers the other housing half including the gear drum located therein, if one housing half, in the case shown the lower 6, is in the Direction of arrow ii against the other housing half 5 is shifted in some way (Fig. 3).
Urr die Zahnradtrommel in der einen Gehäusehälfte beim Verschieben der anderen Gehäusehälfte am Umfange dicht abzudecken und sie in der Drehung nicht zu hindern, sind die lappenförmigen Verlängerungen g und io mit je einer dem Umfange der Zahnradtrommel in der anderen Gehäusehälfte sich anschmiegenden kreisbogenförmigen Ausbauchung versehen.Urr the gear drum in one half of the housing when moving to cover the other half of the housing tightly around the circumference and not to rotate it to prevent, the lobe-shaped extensions g and io are each one of the circumference the gear drum in the other half of the housing nestling in the shape of an arc of a circle Bulge provided.
Die beiden Gehäusehälften werden bei der Verschiebung gegeneinander durch die haken förmige Ausbildung i2,- 13 der einen Gehäusehälfte aufeinander dicht geführt.The two housing halves are guided tightly against each other by the hook-shaped design i2, - 13 of the one housing half when they are shifted against each other.
