Description

  

  Dichtung zwischen sich relativ zueinander drehenden Maschinenteilen    Die Erfindung bezieht sich auf eine Dichtung zwi  schen relativ zueinander drehenden Maschinenteilen, wie  sie     insbesondere    da verwendet wird, wo das Eindringen  von Schmiermitteln oder Flüssigkeiten in zwei Räumen  entlang einer Welle oder das Austreten derartiger Me  dien aus einem Lager oder dergleichen verhindert wer  den soll.  



  Die Erfindung     betrifft    eine     Dichtung,    die aus einem  schon     bekannten    Dichtungsring besteht, dir an einer  Welle anliegt. Um nun die Eigenschaften der Dichtung  zu verbessern, wird die Welle an der Berührungszone  des Dichtungsringes mit einem Schutzbelag aus Bronze  versehen.  



  Durch     diesen    Schutzbelag wird die Abnützung des  Dichtungsringes und der Welle stark herabgesetzt und  somit die Störungsanfälligkeit dieser Maschinenteile ver  ringert.  



  Beim .in der Zeichnung dargestellten Ausführungs  beispiel geschieht das Versehen der Welle 3 mit dem  Schutzbelag 1 denkbar einfach. In die Welle 3 wird für  diesen Zweck eine Nut 4 eingestochen und in diese der  Schutzbelag 1     heiss    eingespritzt. Die Welle 3 wird danach  zusammen mit dem Schutzbelag 1     überschliffen.    Der  Schutzbelag 1 arbeitet mit dem Dichtungsring 2 zusam  men. Die Welle 3 ist im Lager 5 gelagert.    Die Tiefe der in die Welle 3 eingestochenen Nut 4  ist vom Wellendurchmesser abhängig.

   Sie beträgt zum  Beispiel:  
EMI0001.0008     
  
    Wellendurchmesser: <SEP> Nutentiefe:
<tb>  bis <SEP> 30 <SEP> mm <SEP> etwa <SEP> 0,5 <SEP> mm
<tb>  von <SEP> 30 <SEP> mm <SEP> bis <SEP> 50 <SEP> mm <SEP> etwa <SEP> 0,75 <SEP> mm
<tb>  von <SEP> 50 <SEP> mm <SEP> bis <SEP> 75 <SEP> mm <SEP> etwa <SEP> 1,0 <SEP> mm
<tb>  von <SEP> 75 <SEP> mm <SEP> bis <SEP> 100 <SEP> mm <SEP> etwa <SEP> 1,5 <SEP> mm



  Seal between relatively rotating machine parts The invention relates to a seal between relatively rotating machine parts, as it is used in particular where the penetration of lubricants or liquids in two spaces along a shaft or the escape of such media from a warehouse or the like prevented who should.



  The invention relates to a seal which consists of an already known sealing ring, which rests against a shaft. In order to improve the properties of the seal, the shaft is provided with a protective covering made of bronze at the contact zone of the sealing ring.



  This protective covering greatly reduces the wear and tear on the sealing ring and the shaft and thus reduces the susceptibility of these machine parts to malfunction.



  In the embodiment shown in the drawing, providing the shaft 3 with the protective covering 1 is very easy. For this purpose, a groove 4 is pierced into the shaft 3 and the protective covering 1 is hot-injected into it. The shaft 3 is then ground over together with the protective covering 1. The protective covering 1 works together with the sealing ring 2 men. The shaft 3 is supported in the bearing 5. The depth of the groove 4 made in the shaft 3 depends on the shaft diameter.

   It amounts, for example:
EMI0001.0008
  
    Shaft diameter: <SEP> groove depth:
<tb> to <SEP> 30 <SEP> mm <SEP> about <SEP> 0.5 <SEP> mm
<tb> from <SEP> 30 <SEP> mm <SEP> to <SEP> 50 <SEP> mm <SEP> about <SEP> 0.75 <SEP> mm
<tb> from <SEP> 50 <SEP> mm <SEP> to <SEP> 75 <SEP> mm <SEP> about <SEP> 1.0 <SEP> mm
<tb> from <SEP> 75 <SEP> mm <SEP> to <SEP> 100 <SEP> mm <SEP> about <SEP> 1.5 <SEP> mm
