Description

Zahnradpumpe für Kunstseidenspinnmaschinen mit einem das treibende Pumpenrad und das äußere Antriebsrad kuppelnden Zwischenglied Die vorliegende Erfindung betrifft eine Zahnradpumpe für Kunstseidenspinnmaschinen zur Förderung der Spinnmasse.Gear pump for rayon spinning machines with a driving force The impeller and the intermediate member coupling the outer drive wheel The present invention relates to a gear pump for rayon spinning machines to convey the spinning mass.

Bei diesen Pumpen ist es bekannt, die Antriebswelle für das treibende Pumpenrad, die außen das Antriebsrad trägt, aus der Pumpe herauszuführen oder das Antriebsrad auf dem Gehäuse zu lagern und mit dem Pumpenrad zu kuppeln. Für diese Kupplung ist unter anderem ein Zwischenglied vorgeschlagen, das einerseits in das Pumpenrad, andererseits in das Antriebsrad eingreift. Es ist weiterhin auch bekannt, das treibende Pumpenrad auf einem im Gehäuse gelagerten Bolzen anzuordnen, welcher in unmittelbarer Verbindung mit der Antriebswelle steht. Alle diese Ausführungen haben den Nachteil, daß die austretende Spinnmasse mit der Lagerstelle der Antriebswelle in Berührung kommen kann, worauf die Spinnmasse infolge Luftzutritts kristallisiert und so einen frühzeitigen Verschleiß der Lagerstellen und der Welle herbeiführt.In these pumps, it is known that the drive shaft for the driving Pump wheel, which carries the drive wheel on the outside, out of the pump or the To store the drive wheel on the housing and to couple with the pump wheel. For this Coupling is proposed, among other things, an intermediate member that on the one hand in the Pump wheel, on the other hand, engages in the drive wheel. It is also known to arrange the driving impeller on a bolt mounted in the housing, which is in direct contact with the drive shaft. All of these designs have the disadvantage that the escaping spinning mass with the bearing point of the drive shaft can come into contact, whereupon the spinning mass crystallizes as a result of the ingress of air and thus causes premature wear of the bearings and the shaft.

Durch die vorliegende Erfindung soll dieser Nachteil beseitigt werden.This disadvantage is to be eliminated by the present invention.

Dieselbe besteht darin, daß das das treibende Pumpenrad und die Antriebswelle verbindende Zwischenglied einerseits in einen das treibende Pumpenrad tragenden Bolzen eingreift, andererseits in der als Hohlwelle ausgebildeten, mit einer nach außen führenden Bohrung versehenen Antriebswelle gelagert ist.The same consists in that the driving impeller and the drive shaft connecting intermediate member on the one hand in a bearing the driving pump wheel Bolt engages, on the other hand, in the hollow shaft designed with one after outside leading bore provided drive shaft is mounted.

Bei der Bauart nach der Erfindung besteht die Möglichkeit, den Austritt der Spinnmasse durch Anbringen einer Abdichtung am Bolzen des treibenden Pumpenrades auf ein Mindestmaß herabzudrücken; tritt doch noch Spinnmasse aus, so wird sie am Zwischenglied entlang in die Hohlwelle und von hier durch die nach außen führende Bohrung abgeleitet, ohne daß eine Berührung mit der Lagerstelle der Antriebswelle vorkommt.In the design according to the invention there is the possibility of the exit the spinning mass by attaching a seal to the bolt of the driving impeller press down to a minimum; if spinning mass still emerges, it becomes on Intermediate member along into the hollow shaft and from here through the leading to the outside Bore derived without coming into contact with the bearing point of the drive shaft occurs.

Die Zeichnung stellt den Erfindungsgegenstand in einer beispielsweisen Ausführungsform dar; und zwar zeigt Fig. i eine Pumpe im Längsschnitt, Fig. 2 einen Schnitt nach der Linie A-B der Fig. i.The drawing represents the subject matter of the invention in an exemplary manner Embodiment; namely FIG. 1 shows a pump in longitudinal section, FIG. 2 shows one Section along the line A-B of Fig. I.

Der Pumpenkörper besteht aus der Vorderplatte i, Mittelplatte 2 und Rückplatte g und ist mit dem Antriebskörper bzw. Anschraubstück q. verbunden. In der Mittelplatte 2 sind die Pumpenräder 5 und 6 angeordnet, wovon das treibende Pumpenrad 5 auf einem im Pumpenkörper gelagerten Bolzen 7 angeordnet ist. Im Antriebskörper q. ist die einerseits als Hohlwelle ausgebildete Antriebswelle 9 gelagert, welche außen das in der Zeichnung nicht dargestellte Antriebsrad trägt und im Innern mit der nach außen hin durchgehenden Bohrung io versehen ist. Die Verbindung zwischen der Antriebswelle 9 und dem Bolzen 7 erfolgt durch das Zwischenglied 8 mit kantigem Querschnitt, welches beiderseits in die Wellen eingreift. Die Antriebswelle 9 kann mit einer Fettschmierung versehen werden.The pump body consists of the front plate i, middle plate 2 and Back plate g and is connected to the drive body or screw-on piece q. tied together. In the center plate 2, the pump wheels 5 and 6 are arranged, of which the driving Pump wheel 5 is arranged on a bolt 7 mounted in the pump body. In the drive body q. the one hand designed as a hollow shaft drive shaft 9 is mounted, which outside carries the drive wheel, not shown in the drawing, and inside with the outwardly continuous bore io is provided. The connection between the drive shaft 9 and the bolt 7 takes place through the intermediate member 8 with angular Cross-section, which engages in the shafts on both sides. The drive shaft 9 can be provided with grease lubrication.
