Description

Zahnradpumpe für die Förderung von Viskose zu den Spinndüsen von Kunstfaserspinnmaschinen. Vorliegende Erfindung betrifft Zahnradpumpen, die bei der Herstellung von Kunstseide und sonstigen Kunstfasern zur Förderung der Viskose zu den Spinndüsen Verwendung finden und unter der Bezeichnung »Spinnzahnradpumpen« bekannt sind.Gear pump for conveying viscose to the spinnerets of synthetic fiber spinning machines. The present invention relates to gear pumps used in the manufacture of rayon and other synthetic fibers to use to convey the viscose to the spinnerets and are known as "spinning gear pumps".

Die Erfindung besteht darin, daß die an sich bekannten Zwischenplatten, die zwischen der eigentlichen Gehäuseplatte und den beiden Deckelplatten' angeordnet und mittels durchgehender Schrauben mit der Gehäuseplatte und den Deckelplatten dicht verbunden werden, oder die Deckelplatten an den einander zugekehrten Seiten mit Nuten versehen sind, die zur Zu- und Ableitung der Viskose nach und von den Pumpenarbeitsräumen dienen und hierbei die Lagerstellen der Zahnradachsen durchlaufen.The invention consists in that the intermediate plates known per se, which are arranged between the actual housing plate and the two cover plates' and by means of through screws with the housing plate and the cover plates are tightly connected, or the cover plates on the sides facing each other are provided with grooves for the supply and discharge of the viscose to and from the Serve pump working spaces and pass through the bearing points of the gear axles.

Die Vorteile dieser Bauart bestehen darin, daß erstens die Verwendung eingegossener Nuten ermöglicht ist, wodurch das seither übliche umständliche und teure Bohren der Kanäle in Wegfall kommt, und daß zweitens infolge des Durchlaufens der Kanäle durch die Lagerstellen die letzteren stets ausreichend geschmiert und gekühlt sind und ein Festsetzen und Erhärten der in die Lagerstellen eingedrungenen Viskose und damit ein Festklemmen oder Anfressen der Achsen nicht stattfinden kann.The advantages of this design are that, firstly, the use Cast-in grooves is made possible, whereby the cumbersome and common since then expensive drilling of the channels is eliminated, and that secondly as a result of traversing of the channels through the bearings, the latter is always adequately lubricated and are cooled and a setting and hardening of the penetrated into the bearing points Viscous and thus the axles cannot get stuck or seized.

Die Zeichnung zeigt den Erfindungsgegenstand in Abb. i im Längsschnitt, während Abb. 2 eine Seitenansicht in Pfeilrichtung A bei abgenommener Deckelplatte k und Abb. 3 eine Seitenansicht in Pfeilrichtung B bei abgenommener Deckelplatte l und geschnittener Antriebswelle d darstellt.The drawing shows the subject of the invention in Fig. I in longitudinal section, while Fig. 2 is a side view in the direction of arrow A with the cover plate removed k and Fig. 3 a side view in the direction of arrow B with the cover plate removed l and section drive shaft d represents.

In der Gehäuseplatte a laufen die beiden dicht eingepaßten Zahnräder b und c, die- auf den Achsen d und e befestigt und durch die erste, beispielsweise in Pfeilrichtung f, angetrieben werden. 'Die Platte a und die Seitenflächen der Zahnräder b und c sind durch die Zwischenplatten g und h abgedichtet, die mit den an den Lagerstellen der Zahnradachsen vorbeigehenden Zu- bzw. Abführungsnuten i versehen und wiederum durch die Deckelplatten k und L gedichtet sind. Diese besitzen die Anschlüsse in für die Zu- und Ableitung der Viskose. Sämtliche Platten werden durch die Schrauben 7a zusammengehalten. Die Abdichtung der Antriebswelle erfolgt durch die Stopfbüchse o mit Überwurfmutter p. Die Strömung der Viskose in den Kanälen i und in erfolgt durch die gezeichnete Drehrichtung im Sinne- der in die Kanäle eingezeichneten Pfeile.In the housing plate a run the two tightly fitted gears b and c, which are attached to the axes d and e and are driven by the first, for example in the direction of arrow f. The plate a and the side surfaces of the gears b and c are sealed by the intermediate plates g and h, which are provided with the supply and discharge grooves i that pass the bearing points of the gear axles and are in turn sealed by the cover plates k and L. These have the connections in for the supply and discharge of the viscose. All plates are held together by the screws 7a. The drive shaft is sealed by the stuffing box o with union nut p. The flow of the viscose in the channels i and in takes place through the direction of rotation drawn in the sense of the arrows drawn in the channels.

Bemerkt sei noch, daß es bedeutungslos ist, ob die Nuten i in den Zwischenplatten g und h oder den Deckelplatten k und L oder in diesen und jenen zugleich angeordnet sind, sie müssen lediglich zwischen g und k und h und L liegen.It should also be noted that it is irrelevant whether the grooves i are arranged in the intermediate plates g and h or the cover plates k and L or in these and those at the same time; they only have to be between g and k and h and L.
