Description

Abdichtungsvorrichtung für Zahnradpumpen, insbesondere zur Förderung von Viskose. ylit vorliegender Erfindung wird bezweckt, die durch den nicht zu vermeidenden Verschleiß der Zahnräder bei Zahnradpumpen entstehenden Undichtheiten und die hierdurch hervorgerufene ungleichmäßige Förderung zu beseitigen. Gegenüber bekannten Vorrichtungen, bei denen das die Zahnräder umgebende Gehäuse nachstellbar ist, besteht das Neue darin, daß Teile dieser Gehäuse federn und von Druckschrauben bewegt werden. Diese federnden Teile befinden sich zweckmäßig gegenüber der Eingriffstelle der Zahnräder, so daß die dort entstandenen Undichtheiten schnell und leicht beseitigt werden können, indem diese federnden Gehäuseteile gegen die Zahnradkränze gedrückt werden.Sealing device for gear pumps, in particular for conveying of viscose. ylit of the present invention is intended to be avoided by the inevitable Wear of the gears in gear pumps and the resulting leaks to eliminate the uneven conveyance caused. Compared to known devices, in which the housing surrounding the gears can be readjusted, there is something new in that parts of this housing spring and are moved by pressure screws. These Resilient parts are conveniently located opposite the point of engagement of the gears, so that the leaks that have arisen there can be eliminated quickly and easily, by pressing these resilient housing parts against the ring gears.

Auf der Zeichnung ist eine Zahnradpumpe nach der Erfindung in .einer Ausführungsform beispielsweise dargestellt, und zwar zeigen Abb. i die Pumpe im Längsschnitt, Abb. 2 das Zahnradgehäuse in Vorderansicht und Abb. 3 die Lagerung eines Zahnrades vergrößert.In the drawing, a gear pump according to the invention is in .einer Embodiment shown for example, namely Fig. I show the pump in Longitudinal section, Fig. 2 the gear housing in front view and Fig. 3 the bearing of a gear enlarged.

Die Platten a und b bedecken in bekannter Weise die Platte c, welche als Gehäuse für die Zahnräder d und e dient. Das Zahnrad d ist mit der Antriebsspindel f durch einen in dieser lose steckenden Stift g verbunden. Das Zahnrad e ist auf einem Ring h lose gelagert und dieser auf einer Kopfschraube i drehbar angeordnet (Abb. 3). Zwischen dem Ringh und der Schraube i ist ein kleiner Hohlraum k vorgesehen. Im Gehäuse c befinden sich Schlitze m, von denen Spalte ta nach den Rädern d bzw. e führen, während Schrauben o die so gespalteten Gehäuseteile p, u an die Zahnräder ,d und e andrücken. Sofern sich das Gehäuse c in der Umgebung der Zahnräder d, e oder die Zähne der letzteren merkbar abgenutzt haben, werden die Gehäuseteile p und u durch die Schrauben o entsprechend nach innen gedrückt. Infolge des vorhandenen Hohlraums k kann auch der Drehpunkt des Zahnrades e verändert werden. Desgleichen empfiehlt .es sich, das lose mitgenommene Antriebsradd mit einem Luftspalt zu umgeben, um dem durch seitlichen Druck der Spindel f ,entstehenden Verschleiß der Gehäuseteile d und b vorzubeugen.The plates a and b cover, in a known manner, the plate c, which serves as a housing for the gears d and e . The gear wheel d is connected to the drive spindle f by a pin g loosely inserted therein. The gear wheel e is loosely mounted on a ring h and this is rotatably arranged on a head screw i (Fig. 3). A small cavity k is provided between the ring h and the screw i. In the housing c there are slots m, from which gaps ta lead to the wheels d and e, while screws o press the housing parts p, u that are split in this way onto the gears, d and e. If the housing c in the vicinity of the gears d, e or the teeth of the latter have noticeably worn down, the housing parts p and u are correspondingly pressed inwards by the screws o. As a result of the existing cavity k, the pivot point of the gear wheel e can also be changed. It is also advisable to surround the loosely entrained drive wheel d with an air gap in order to prevent wear of the housing parts d and b caused by lateral pressure from the spindle f.
