Abstract

The object of the invention is to seal off an opening for the passage of a shaft in a maching having a rotor for the treatment of fluid media. Between the working space of the housing and of the shaft bearing, the housing surface opposite the rotor is, according to the invention, designed as a cavity in the form of an inner spherical sector and the rotor, which is secured on the shaft and rotates with it and which has the same spherical curvature but is in the form of the surface of a spherical sector, is arranged with the minimum possible clearance relative to the housing surface, without metallic friction, the interspace which forms between the housing and the rotor thus representing a parallel channel. As a result, a sufficiently strong flow pressure to prevent the fluid to be treated from forcing its way out of the working space, beyond the channel and to the opening for the passage of the shaft is built up in the said channel during the movement of the rotor, even at the minimum speed of rotation.

Beschreibung:Description:

Entgegen der Ausführung nach P 3^ ^O 6O6, wobei der Rotorläufer in einer Krümmung nach innen gehend einen Hohlraum bildet, ist der hier beschriebene Rotorläufer in der Form eines Kugelausschnitts ausgebildet, wie der Längsschnitt der Abbildung nach Teil 1 zeigt.Contrary to the version according to P 3 ^ ^ O 6O6, whereby the rotor rotor Forms a cavity going inwards in a curve, the rotor rotor described here is in the form of a spherical section formed, as the longitudinal section of the figure after part 1 shows.

Das Gehäuse nach Teil 2 der Abbildung der Maschine ist derart als Hohlraum ausgebildet, daß der kugelförmige Rotorläufer ( 1 ) von der Fläche des Gehäuses ( 2 ) in der Größe über den gesamten Durchmesser sozusagen eingebettet umgeben wird.The housing according to part 2 of the illustration of the machine is designed as a cavity in such a way that the spherical rotor rotor (1) is surrounded by the surface of the housing (2) embedded in size over the entire diameter, so to speak.

Der Rotorläufer ist so angeordnet, daß er mit seiner Fläche die ihm gegenüber angeordnete Fläche des Gehäuses nicht berührt und somit zwischen Rotorläufer und Gehäuse ein erforderlicher Zwischenraum entsteht·The rotor rotor is arranged in such a way that it does not have the surface of the housing arranged opposite it with its surface touches and thus a necessary space is created between rotor rotor and housing

Einerseits gewährleistet der Zwischenraum das berührungslose Vorbeigleiten des Rotorläufers an der Gehäusewand, andererseits bildet sich infolge der Rotorbewegung während des Betriebes in dem Zwischenraum eine erfindungsgemäß gewollte Saugströmung aus, die durch ihre Stärke das Eindringen von Flüssigkeit in eben diesen Zwischenraum verhindert. On the one hand, the gap ensures that the rotor rotor glides past the housing wall without contact, on the other hand, as a result of the rotor movement during operation, an according to the invention is formed in the intermediate space intentional suction flow, the strength of which prevents liquid from penetrating into this space.

In diesem Zusammenhang sei z.B. auf die spürbare Wirkung in einem U-Bahnschacht hingewiesen, in dem während der Durchfahrt eines U-Bahnzuges eine enorme Saugströmung auftritt. Ebenso bewirkt die Saugströmung bei Fluggeräten - z.B. Motor- oder Segelflugzeugen - das Abheben vom Boden und: das in der Luft schweben. Wie bekannt , sind die Oberseiten der Tragflächen bei diesen Fluggeräten bogenförmig nach außen ausgebildet, um der Luft eine größere Angriffsfläche zu bieten.In this context, reference should be made, for example, to the noticeable effect in a subway shaft, in which during the An enormous suction flow occurs when a subway train passes through it. The same is true of the suction flow in aircraft - e.g. motor planes or gliders - taking off from the ground and: floating in the air. As is known, the tops are The wings of these aircraft are curved outwards to give the air a larger surface to offer.

Erfindungsgemäß hat sich gezeigt, daß die bogenförmige Ausbildung in der Form eines Kugelausschnitts des Rotorläufers eine genügend große Oberfläche bietet, um während der Bota·* tion eine entsprechende Saugströmungskraft hervorzurufen, wodurch das Eindringen von Flüssigkeit in den Zwischenraum verhindert wird. Ein anderer Weg als dieser vom Rotorläufer zur Wellendurchtrittsoffnung im Maschinengehäuse ist nicht / vorhanden. ΓAccording to the invention it has been shown that the arcuate design in the form of a spherical section of the rotor rotor offers a sufficiently large surface to during the bota * tion to produce a corresponding suction flow force, whereby the penetration of liquid into the space is prevented. Another way than this from the rotor rotor to the shaft passage opening in the machine housing is not / available. Γ

Die. bogenförmige Ausbildung in Kugelform bietet den Vorteil, daß gegenüber einer Planfläche mit gleicher Flächenwirkung, die Baugröße im Durchmesser der Maschine verringert werden kann, bei gleichem Wirkungsgrad.The. arcuate design in spherical shape offers the advantage that compared to a plane surface with the same surface effect, the size in the diameter of the machine can be reduced with the same efficiency.
