Description

  

  Stopfbüchse für umlaufende Wellen.    Den Gegenstand der vorliegenden Erfin  dung bildet eine Stopfbüchse für umlaufende  Wellen, die auf der Zeichnung in einem Aus  führungsbeispiel durch     achsialen    Schnitt, dar  gestellt ist.  



  a ist die umlaufende Welle, die eine zum  Beispiel aus Kompositionsmetall bestehende  Büchse c trägt, welche durch eine Mutter b  gegen einen Absatz der Welle gedrückt und  dadurch auf letzterer festgehalten wird.  



  Die Büchse c ist von einem Abdichtungs  kolben d umgeben, der an jeder Stirnseite  einen Dichtungsring e und am Umfange zwei  Kolbenringe f trägt und in welchem die  Büchse c auf Kugeln<I>g</I> läuft. Ein Ring<I>h,</I>  der auf die Büchse c geschraubt ist, hält den  Kolben d auf der Büchse, die gegen Drehung  durch eine oder mehrere Schrauben i gesichert  ist, die im Flansche     1c    stecken. Durch letz  teren und den Kolben d hindurch ist an den  zwischen diesem und der Büchse c befind-    liehen Hohlraum ein Schmierkanal l gelegt  zwecks     Schmierens    der Kugeln     1/.     



       Durelr    Zwischenraum zwischen Büchse c       lind    Kolben d einerseits und dem Flansche       I,    anderseits ist dafür     gesorgt,    dar sich Welle,  Kolben und Büchse ausdehnen können.  



  Die dargestellte Stopfbüchse kann bei  hohem Drucke zugleich als Entlastungskolben  dienen. Die Anzahl der Ringe e und f kann  verschieden gewählt werden.



  Stuffing box for rotating shafts. The subject matter of the present inven tion is a stuffing box for rotating shafts, which is shown on the drawing in an exemplary embodiment by axial section.



  a is the rotating shaft that carries a sleeve c, for example made of composite metal, which is pressed against a shoulder of the shaft by a nut b and is thereby held on the latter.



  The sleeve c is surrounded by a sealing piston d, which carries a sealing ring e on each end face and two piston rings f around the circumference and in which the sleeve c runs on balls <I> g </I>. A ring <I> h </I> screwed onto the sleeve c holds the piston d on the sleeve, which is secured against rotation by one or more screws i inserted in the flange 1c. Through the latter and the piston d, a lubrication channel l is placed on the cavity between this and the bushing c for the purpose of lubricating the balls 1 /.



       The space between the liner c and piston d on the one hand and the flange I on the other hand ensures that the shaft, piston and liner can expand.



  The stuffing box shown can also serve as a relief piston at high pressures. The number of rings e and f can be chosen differently.
