Description

Waagerechte Schubschleuder Die Erfindung betrifft eine waagerechte :Schubschleuder mit einem in der Schleudertrommel axial beweglichen Entleerungseinsatz, der durch einen außerhalb der Schleudertrommel angeordneten Druckzylinder über eine Schubstange hin und her bewegt wird, die ihrerseits durch die als Hohlwelle ausgebildete Schleuderwelle hindurchgeführt ist. Besonders schwierig gestaltet sich bei dieser Sondergattung von Schleudermaschinen das einwandfreie Abdichten der hohlen Schleuderwelle an der Austrittsstelle der Schubstange innerhalb der Schleudertrommel, da auf alle Fälle vermieden werden muß, daß noch so kleine Mengen Druck- bzw. Schmieröl aus der hohlen Schleuderwelle in die Schleudertrömmel gelangen. U m eine sichere Abdichtung zu erzielen, wird erfindungsgemäß dafür gesorgt, daß die Druckstange frei von Biegungskräften bleibt, die erfahrungsgemäß in kürzester Zeit die Abdichtung der Hohlwelle beeinträchtigen.Horizontal thruster The invention relates to a horizontal thruster : Thrust slinger with an emptying insert that is axially movable in the centrifugal drum, by a pressure cylinder arranged outside the centrifugal drum via a Push rod is moved back and forth, which in turn is formed by the hollow shaft Centrifugal wave is passed through. This is particularly difficult Special type of centrifugal machine the perfect sealing of the hollow centrifugal shaft at the exit point of the push rod inside the centrifugal drum, there on all Cases must be avoided that even the smallest amounts of pressure or lubricating oil from the hollow centrifugal shaft get into the centrifugal drum. To ensure a secure seal to achieve, it is ensured according to the invention that the push rod is free from bending forces remains, which experience has shown to impair the sealing of the hollow shaft in a very short time.

Gemäß der Erfindung wird die Schubstange im wesentlichen nur auf ihren beiden Enden, d. h. außerhalb der hohlen Schleuderwelle geführt, und zwar einerseits durch den Kolben im Druckzylinder und andererseits durch den Schubboden in der- Schleudertrommel. Auf diese Weise bleibt die Abdichtung der Hohlwelle gegenüber der Schleudertrommel frei von schädlichen Beanspruchungen.According to the invention, the push rod is essentially only on their both ends, d. H. out of the hollow centrifugal shaft, on the one hand through the piston in the pressure cylinder and, on the other hand, through the push floor in the Centrifugal drum. In this way, the seal against the hollow shaft remains the centrifugal drum free from harmful stresses.

Auf der Zeichnung ist ein Ausführungsbeispiel der Schubschleuder gemäß der Erfindung schematisch im Längsmittelschnitt unter Fortlassung der für die Erfindung unwesentlichen Teile dargestellt.In the drawing, an embodiment of the thruster is shown in accordance with the invention schematically in longitudinal center section omitting the for the invention insignificant parts shown.

Die Schleudertrommel i sitzt frei fliegend auf der waagerechten hohlem Schleuderwelle 2. Die Schleuderwelle läuft in den beiden Lagern 3, q., zwischen denen sie zu dem Druckölzylinder 5 erweitert ist. Der Druckölzylinder enthält den verschiebbaren Kolben 6, der wechselseitig mit Drucköl beaufschlagt wird, das bei 7 und 8 durch die hohle Schleuderwelle 2 zu- bzw. abgeführt wird. An dem Kolben 6 ist die Schubstange g angebracht, die die hohle Schleuderwelle 2 durchsetzt und mit ihrem in der Schleudertrommel befindlichen Ende mit dem Boden des Schubbodens io starr verbunden ist. Der in der Schleudertrommel i - axial verschiebbare Schubboden ist nahe seinem Umfang mit Längsstegen i i versehen, an denen ein Trommelabdeckring 12 angebracht ist. Die Schleuderwelle 2 ist an der Austrittsstelle der Schubstange 9 durch die Stopfbuchse 13 abgedichtet. Das axial verschiebbare System, bestehend aus dem Schubboden i o, i i, 12, der Schubstange 9 und dem Druckkolben 6, wird. nur auf seinen Enden, und zwar im Druckzylinder 5 und an dem Schubboden io in der Schleudertrommel i geführt. Auf diese Weise bleibt die Stopfbuchse 13 frei von schädlichen Beanspruchungen, so daß eine einwandfreie Abdichtung gegenüber der Schleudertrommel gesichert bleibt.The centrifugal drum i sits freely floating on the horizontal hollow one Centrifugal shaft 2. The centrifugal shaft runs in the two bearings 3, q., Between which it is extended to the pressure oil cylinder 5. The pressure oil cylinder contains the displaceable piston 6, which is alternately acted upon with pressurized oil, which at 7 and 8 is supplied and discharged through the hollow centrifugal shaft 2. On the piston 6, the push rod g is attached, which penetrates the hollow centrifugal shaft 2 and with its end located in the centrifugal drum with the bottom of the push floor io is rigidly connected. The moving floor in the centrifugal drum i - axially movable is provided near its circumference with longitudinal webs i i, on which a drum cover ring 12 is attached. The centrifugal shaft 2 is at the exit point of the push rod 9 sealed by the stuffing box 13. The axially displaceable system, consisting of from the push floor i o, i i, 12, the push rod 9 and the pressure piston 6, is. only on its ends, namely in the pressure cylinder 5 and on the push floor io in the Centrifugal drum i out. In this way, the gland 13 remains free from harmful ones Stresses, so that a perfect seal against the centrifugal drum remains secured.
