Description

  

  Teleskopwelle.    Die Erfindung betrifft eine Teleskopwelle  mit einer Schmiervorrichtung, durch     ;die          Schmiermittel    zwischen die beiden     ineinander     verschiebbaren Wellenteile     eingeführt    wer  den kann.  



  Auf der Zeichnung ist ein Ausführungs  beispiel des Erfindungsgegenstandes in einem  Längsschnitt dargestellt.  



  Es bezeichnet 1 den     innern    und 2 den  äussern der beiden     ineinander        verschiebbaren     Teile der dargestellten Teleskopwelle. Der       Querschnitt    der Welle kann beliebig, z. B.  kreisrund, quadratisch, rechteckig, polygo  nal usw. sein. Der äussere Wellenteil 2 trägt  etwa in der     Längsmitte    seiner     Gleitfläche     einer nach innen offenen, hohlen Ring  und ist auf seinem     Umfang    mit mehreren  Löchern 4 versehen. Auf den Ring 3     ist     ein Anschlussnippel 5 für Druckschmierung  geschraubt.

   Bei Schmiermittelzuführung wird  der Hohlraum des Ringes 3 mit Schmier  mittel .gefüllt, das durch die Löcher 4 zwi-    scheu die beiden Wellenteile 1 und 2     dringt.     Dadurch     wenden    die     Reibungsflächen    der  selben vom     mittleren    Teil nach den beiden  Enden hin mit Schmiermittel versehen, das  heisst das     Schmiermittel    fliesst nach den  Enden der beiden     Wellenteile.    Dadurch wird  nicht nur die gegenseitige Bewegung der       letzteren        erleichtert,    sondern zugleich     ,

  deT        Zu-          tritt    von Staub     etc.        zwischen    die Reibungs  flächen     vermieden    oder eventuell eingedrun  gener     Staub    und     Sand    nach aussen geschoben.

    Demzufolge wird auch die     Abnützung    der  selben     vermindert    und damit die Gefahr     des          Entstehens    von     iSpiel        zwischen    den Wellen  teilen erheblich     herabgesetzt.    Um den     Aus-          tritt        des        ,Schmiermittels    am Ende des     äussern     Wellenteils etwas hintan zu hasten, ist an  diesem Wellenende ein Kopf 6 mit ein  geklemmten     Dichtungsscheiben    7 aus     Filz     aufgesetzt.

   Die     letzteren    halten ausserdem  den     zeitweise    aus dem äussern Wellenteil aus  tretenden Teil der '     Reibungsflächen    des  innern     Wellenteils    frei von Staub     etc.  



  Telescopic shaft. The invention relates to a telescopic shaft with a lubricating device through which the lubricant can be introduced between the two shaft parts which can be slid into one another.



  In the drawing, an embodiment example of the subject invention is shown in a longitudinal section.



  It denotes 1 the inside and 2 the outside of the two mutually displaceable parts of the illustrated telescopic shaft. The cross section of the shaft can be arbitrary, for. B. circular, square, rectangular, polygo nal, etc. be. The outer shaft part 2 carries an inwardly open, hollow ring approximately in the longitudinal center of its sliding surface and is provided with several holes 4 on its circumference. A connection nipple 5 for pressure lubrication is screwed onto the ring 3.

   When lubricant is supplied, the cavity of the ring 3 is filled with lubricant, which penetrates through the holes 4 between the two shaft parts 1 and 2. As a result, the friction surfaces of the same turn from the middle part to the two ends provided with lubricant, i.e. the lubricant flows to the ends of the two shaft parts. This not only facilitates the mutual movement of the latter, but at the same time,

  deT Ingress of dust etc. between the friction surfaces is avoided or any dust and sand that may have penetrated are pushed outwards.

    As a result, the wear and tear of the same is reduced and thus the risk of creating play between the shafts is considerably reduced. To prevent the lubricant from escaping at the end of the outer shaft part, a head 6 with a clamped sealing washer 7 made of felt is placed on this shaft end.

   The latter also keep the part of the friction surfaces of the inner shaft part that temporarily emerges from the outer shaft part free of dust etc.
