Description

  

      Selbstdichtendes    Gleitlager.    Kunstkohle eignet sich bekanntlich wegen  ihrer hervorragenden     Eigenschmierfähigkeit,     ihrem hohen     Wärmeableitvermögen    und ihrer  geringen mechanischen Abnützung sehr gut  als     Gleitlagervwerkstoff.    Es sind zahlreiche  Fälle aus der Praxis, insbesondere aus der  Glas-, Keramik- und Hüttenindustrie be  kannt, bei welchen zylindrische Kunstkohle  lagerbüchsen eine erheblich längere Lebens  dauer als metallische     Gleitslagerbüehsen    zu  verzeichnen hatten.  



  Um diese vorteilhafte Anwendung der  Kunstkohle auch auf solche Gleitlager über  tragen zu können, die neben     ihrer    tragenden  eine abdichtende Funktion haben sollen,  musste ein neuer Weg beschritten werden, um  Wellenträger und Dichtmittel zu vereinen.  



  Die vorliegende Erfindung betrifft ein  selbstdichtendes Gleitlager, dessen Lager  biichse mindestens zum Teil aus Kunstkohle  besteht. Sie ist dadurch gekennzeichnet, dass  die Dichtungselemente aus verformbaren Ab  dichtungsstoffen in Nuten des Kunstkohle  Lagerbüchsenteils verlegt sind.     .Vorteilhaft     werden durch ein nachträglich eingebrachtes  Imprägnier- und Verbundmittel die Abdich  tungsmittel mit dem     Kunstköhlelagerbüchsen-          teil     Das Verbundmittel wird da;  bei zweckmässig so gehalten, dass es die dich  tenden Eigenschaften des Lagerkörpers und  seiner Dichtmedien fördert und unterstützt.  



  Als Dichtmittel können 'je nach Verwen  dungszweck Filz, Hanf- und     Gummigewebe       oder gleichartige, plastisch     bzw.        _    elastisch ver  formbare Abdichtungsstoffe mit rundem,  quadratischem oder dreieckigem Profil in Be  tracht     kommen.    Zweckmässig werden ge  nannte Dichtungselemente vor der Imprägnie  rung in ring- oder     spiralenförmige    Nuten des       Kohlelagerkörpers    durch     Einlegen,    Einpres  sen oder Einkitten so fixiert, dass die aus der  Bohrung des Kohlelagers hervorstehenden  Teile der Dichtungsringe gegenüber dieser  Bohrung ein Untermass aufweisen, welches  bis zum dreifachen Wert des vorgesehenen  Wellenspiels erreichen kann.  



  Die     Anzahl    der     einzulegenden    Dichtungs  elemente kann 1, 2 oder mehr betragen. Sie  richtet sich, ebenso wie die Einbaustellen der  Dichtungselemente innerhalb des Gleitlager  körpers, weitgehend nach den jeweiligen Be  triebserfordernissen.  



       A:bb.1    und 2 der Zeichnung zeigen bei  spielsweise eine Ausführungsform des Erfin  dungsgegenstandes im Längs- und Quer  schnitt.  



  Die Anordnung besteht aus der eigent  lichen Lagerbüchse 1     aus    Kunstkohle, die zur  Erhöhung     der    mechanischen Festigkeit in  eine Stahlhülse 2 gepresst ist. Das zusätz  liche     Aufbringen        dieses    metallischen Stütz  ringen ist nur in aussergewöhnlichen Bela  stungsfällen notwendig; im allgemeinen kann  die Lagerbüchse ohne     besondere        Metallhülse     hergestellt werden.

   Die     Dichtungselemente         sind in Form von Filzringen 3 in die     nut-          artigen    Vertiefungen 4     des        Lagerkörpers    1       eingepresst    und anschliessend durch ein     ge-          eignetes    Imprägnier- und     Verbundmittel,     z. B. Hartwachs, mit diesem zu einem mecha  nisch     festen    Bauelement zusammengefügt.



      Self-sealing plain bearing. Artificial charcoal is known to be very suitable as a plain bearing material because of its excellent self-lubricating properties, its high heat dissipation capacity and its low mechanical wear. There are numerous cases from practice, in particular from the glass, ceramics and metallurgical industry, be known in which cylindrical charcoal bearing bushes had a significantly longer life than metallic sliding bearing bushes.



  In order to be able to carry this advantageous application of charcoal to plain bearings that are supposed to have a sealing function in addition to their load-bearing function, a new approach had to be taken to combine shaft carriers and sealants.



  The present invention relates to a self-sealing sliding bearing, the bearing of which is at least partly made of synthetic carbon. It is characterized in that the sealing elements made of deformable sealing materials are laid in grooves of the synthetic carbon bearing bush part. The sealing means with the synthetic carbon bearing bush part are advantageous through a subsequently introduced impregnation and bonding agent. The bonding agent is there; if kept appropriately so that it promotes and supports the dense properties of the bearing body and its sealing media.



  Depending on the intended use, felt, hemp and rubber fabric or similar, plastic or elastic sealing materials with a round, square or triangular profile can be used as sealing means. Before the impregnation, the sealing elements are appropriately fixed in ring-shaped or spiral-shaped grooves in the carbon bearing body by inserting, pressing or cementing them in such a way that the parts of the sealing rings protruding from the bore of the carbon bearing are undersized compared to this bore, which is up to three times the value the intended shaft clearance can achieve.



  The number of sealing elements to be inserted can be 1, 2 or more. Like the installation locations of the sealing elements within the plain bearing body, it is based largely on the respective operating requirements.



       A: bb.1 and 2 of the drawing show, for example, an embodiment of the subject of the invention in longitudinal and cross-section.



  The arrangement consists of the actual bearing bush 1 made of charcoal, which is pressed into a steel sleeve 2 to increase the mechanical strength. The additional application of this metallic support rings is only necessary in exceptional cases of Bela; In general, the bearing bush can be manufactured without a special metal sleeve.

   The sealing elements are pressed into the groove-like depressions 4 of the bearing body 1 in the form of felt rings 3 and then secured by a suitable impregnating and bonding agent, e.g. B. hard wax, joined with this to form a mechanically solid component.
