Vorliegende Erfindung betrifft eine Schleudermaschine, bei welcher eine unter Druck stehende Flüssigkeit zum Ersatz des gebräuchlichen Spurlagers dient. Es ist bekannt, daß die Schmierung von Spurlagern bei Schleudermaschinen dadurch vermehrt werden kann, daß Öl oder ein sonstiges Schmiermittel unter die Welle gepreßt wird, um das Lager vom Gewicht der Welle zuThe present invention relates to a centrifugal machine in which a pressurized standing liquid is used to replace the common thrust bearing. It is known, that the lubrication of thrust bearings in centrifugal machines is increased oil or another lubricant may be pressed under the shaft, to keep the bearing from the weight of the shaft

Ein Nachteil dieser Anordnung besteht darin, daß das ganze Gewicht der sich drehenden Teile beim Fehlen des Schmiermittels in unmittelbare Berührung mit dem Spurlager kommt, wodurch der betreffende Teil der Welle oder des Lagers infolge Mangels an Schmiermittel beschädigt wird..A disadvantage of this arrangement is that all of the weight of the rotating parts in the absence of lubricant in direct contact with the Thrust bearing occurs, which damages the relevant part of the shaft or bearing due to a lack of lubricant.
Um diesen Übelstand zu vermeiden, werdenTo avoid this evil, be
nacli vorliegender Erfindung zwei Flächen, von denen die eine mit dem sich drehenden Teil der Maschine und die andere mit dem Rahmen der Maschine verbunden ist, derart vorgesehen, daß diese Flächen bei Einführung des Schmiermittels als Lager, beim Fehlen des Schmiermittels jedoch als Bremsflächen wirken.According to the present invention, two surfaces, of which one with the rotating part of the machine and the other with the Frame of the machine is connected, provided that these surfaces upon introduction of the lubricant as a bearing, but in the absence of the lubricant as a braking surface works.
Mit der den Korb tragenden Welle A ist eine Tasse B verbunden, deren innere Bodenfläche in Form einer Reibfläche H ausgebildet ist, welche mit einer entsprechenden Reibfläche J eines feststehenden Teiles der Maschine zusammenarbeitet. Das Druckmittel wird durch das Rohr C zu der in dem feststehenden Teil J gebildeten Aussparung D geführt. Beim Zuführen des Druckmittels wird die Tasse B mit der Welle A gehoben, so daß der bewegliche Teil sich auf einer Flüssigkeitsschicht zwischen den Flächen J und H frei drehen kann. Das zwischen den Flächen / und H entweichende Druckmittel wird durch das Rohr E zur Pumpe zurückgeführt. Ein kleiner Teil des Schmiermittels tritt zwischen Welle A und das feststehende Lager K und dient als Schmiermittel für dieses Lager.. Die Flüssigkeit fällt von dem Lager K auf die Platte L in dem Behälter M, aus welchem sie zu dem Saugraum der Pumpe geführt wird. A cup B is connected to the shaft A carrying the basket, the inner bottom surface of which is designed in the form of a friction surface H which cooperates with a corresponding friction surface J of a stationary part of the machine. The pressure medium is fed through the pipe C to the recess D formed in the fixed part J. When the pressure medium is supplied, the cup B is lifted with the shaft A so that the movable part can rotate freely on a layer of liquid between the surfaces J and H. The pressure medium escaping between the surfaces / and H is returned through the pipe E to the pump. A small part of the lubricant occurs between shaft A and the fixed bearing K and serves as a lubricant for this bearing. The liquid falls from the bearing K onto the plate L in the container M, from which it is led to the suction chamber of the pump.
