Description

Die Erfindung betrifft ein aerodynamisches Lager für Spinn- oder Zwirnringe mit den im Oberbegriff des Anspruches angegebenen Merkmalen.The invention relates to an aerodynamic bearing for spinning or twisting rings with the in the preamble of the claim specified features.

Bei einem bekannten Lager dieser Art (DD-PS 40910) soll das Schmierpolster durch keilförmige Räume zwischen den Laufflächen erzeugt werden. Über die sonstige Gestaltung des Lagers ist nichts bekannt, da in der DD-PS 40910 in erster Linie ein aerostatisches Lager, bei dem das Schmierpolster durch Druckluft erzeugt wird, beschrieben ist.In a known bearing of this type (DD-PS 40910), the lubrication pad should be wedge-shaped Spaces are created between the running surfaces. Nothing is known about the rest of the design of the camp, because in DD-PS 40910 primarily an aerostatic bearing, in which the lubricating pad is generated by compressed air is described.

Ferner gehört durch die DE-OS 2237 327 ein Lager allgemeiner Art zum Stand der Technik. Bei diesem Lager sind in den die Abstützung des rotierenden Teils bewirkenden stationären Lagerflächen gegenläufige Nuten eingebracht, die bei Drehung Schmiermittel fördern. Die Förderung erfolgt nach innen, von wo das Schmiermittel durch ein Filter abgeführt und durch Kanäle den Nuten wieder zugeführt wird. Eine derartige Lagerkonstruktion ist für aerodynamischen Betrieb ungeeignet.Furthermore, DE-OS 2237 327 includes a warehouse general state of the art. This bearing supports the rotating part effecting stationary bearing surfaces counter-rotating grooves introduced, the lubricant when rotating support financially. The conveyance takes place inwards, from where the lubricant is discharged through a filter and is fed back through channels to the grooves. Such a bearing design is for aerodynamic Operation unsuitable.

Der Erfindung liegt die Aufgabe zugrunde, ein Lager der eingangs genannten Art zu schaffen, das eine hohe Betriebssicherheit und Stabilität besitzt.The invention has for its object to provide a bearing of the type mentioned, the one has high operational reliability and stability.

ίο Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Patentanspruches angegebenen Maßnahmen gelöst. Durch die Nuten erfolgt eine selbsttätige Pumpwirkung, durch die nicht nur das Schmierpolster aufgebaut wird, sondern auch die Luft in die Außenbereiche der Lagerflächen gefördert wird, aus denen sie ungehindert abströmen und Verunreinigungen mitnehmen kann. Weil die Luftansaugung ausschließlich durch Ansaugkanäle für gefilterte Luft erfolgt, ist eine Beeinträchtigung des Lagerbe-ίο This task is achieved according to the invention by the characterizing part of the claim specified measures resolved. Takes place through the grooves an automatic pumping action that not only builds up the lubrication pad, but also the Air is conveyed to the outside areas of the storage areas from which it can flow unhindered and take impurities with it. Because the air intake takes place exclusively through intake ducts for filtered air, an impairment of the storage

Fig. 4 einen Schnitt durch den Lagerstator.4 shows a section through the bearing stator.

Das Faserbändchen 5 wird durch einen Fadenführer zum Ringläufer 2 geleitet. Das vom Ringläufer 2 kommende Garn wird auf der Spindel 3 aufgewickelt. Der Ringläufer 2 gleitet auf dem Rotor 1, der in der Ringbank 4 gelagert ist.The fiber ribbon 5 is guided to the ring traveler 2 by a thread guide. The one from the ring traveler 2 incoming yarn is wound on the spindle 3. The ring traveler 2 slides on the rotor 1, which is in the Ring rail 4 is stored.

An der ebenen Fläche des Lagerrotors 1 sind spiralförmige Nuten 7, an der zylindrischen Lagerfläche schräge Nutenreihen 8, 9 angebracht. Durch die Nuten 7 und 8, 9 wird bei Drehung des Rotors 1 über die Kanäle 10 und 11 des Lagerstators 6 gefilterte Luft angesaugt.On the flat surface of the bearing rotor 1 are spiral grooves 7, on the cylindrical bearing surface inclined rows of grooves 8, 9 attached. Through the grooves 7 and 8, 9 is when the rotor 1 rotates the channels 10 and 11 of the bearing stator 6 sucked in filtered air.

Die gefilterte Luft gelangt über die Leitung 14 in den Kanal 13 der Ringbank 4, der in einer ringförmigen Ausnehmung mündet. Der Lagerstator 6 besteht aus einem metallischen-Werkstoff und ist in der axialen und radialen Lagerfläche mit einem Kunststoffbelag 15 aus Polytetrafluorethylen ausgkleidet. Die Kanäle 11 im Kunststoffbelag 15 münden in einer ringförmigen Nut 12. Der Lagerrotor 1 besteht aus Stahl. Die Nuten 7 und 8, 9 sind durch Ätzen eingebracht. The filtered air passes through the line 14 into the channel 13 of the ring rail 4, which is in an annular Opening opens. The bearing stator 6 consists of a metallic material and is axial and radial bearing surface lined with a plastic coating 15 made of polytetrafluoroethylene. The channels 11 in the plastic covering 15 open into an annular groove 12. The bearing rotor 1 consists of Stole. The grooves 7 and 8, 9 are made by etching.
