Description

  

  Einlagering     für    geteilte Seilrollen    Die Erfindung betrifft eine Weiterentwicklung  des Einlageringes für geteilte Seilrollen gemäss Haupt  patent Nr.<B>326283.</B>  



  Der Patentanspruch des Hauptpatentes bezieht  sich auf einen Einlagering .für geteilte Seilrollen, der  aus elastischem, ölbeständigem Material besteht und  bei dem im innern Teil des Ringkörpers eine Gewebe  einlage, zum Beispiel eines Kreuz- oder Cordgewebes,  in mehreren Schichten vorgesehen ist, wobei vor  zugsweise die Flanken des Ringes für konische  Einspannung planparallel und für planparallele  Einspannung des Ringes in der Seilrolle gegen  die Ringinnenseite hin konisch verlaufen. Gemäss  einer beispielsweisen Ausführungsform des Einlage  ringes wurde als elastisches Material für den Ring  teil über den Kreuz- oder Cordgeweben als Gewebe  einlagen einheitlich Weichgummi verwendet.

   Es wurde  nun festgestellt, dass durch die     Walkbewegung    des  Gummis in der     Seilrollenrille    ein Verschleiss an den  Flanken des Einlageringes auftritt, was zu einer  frühzeitigen Zerstörung des Ringes selbst führt.  



  Die zusätzliche Erfindung bezweckt, den den Ring  zerstörenden Verschleiss an den Ringflanken zu ver  hindern.     Erfindungsgemäss    ist zwischen den     Kreuz-          oder    Cordgeweben des innern Ringteiles und einem    äussern Ringteil aus elastischem Material eine Zwi  schenschicht aus härterem elastischem, ebenfalls     öl-          beständigem    Material vorgesehen.  



  In der Zeichnung ist vom erfindungsgemässen  Einlagering ein Ausführungsbeispiel im Querschnitt  veranschaulicht.  



  Der Einlagering für geteilte Seilrollen setzt sich  aus einem     innern    Ringteil mit mehreren Kreuz- oder       Cordgewebelagen    1, einer Zwischenschicht 2 aus  einem härteren elastischen, ölbeständigen Material,  zum Beispiel einer entsprechenden Gummimischung,  und dem äussern Ringteil 3 aus weicherem elastischem,  ölbeständigem Material, zum Beispiel Weichgummi,  zusammen. Durch die härtere Zwischenschicht 2 wird  die schädliche Wirkung des     Walkens    stark vermindert  und damit die Laufzeit des     Einlageringes    bedeutend  verlängert.



  Insert ring for split rope pulleys The invention relates to a further development of the insert ring for split rope pulleys according to main patent no. <B> 326283. </B>



  The claim of the main patent relates to an insert ring .für divided pulleys, which consists of elastic, oil-resistant material and in which a fabric insert, for example a cross or cord fabric, is provided in several layers in the inner part of the ring body, preferably in front the flanks of the ring for conical clamping are plane-parallel and for plane-parallel clamping of the ring in the pulley are conical towards the inside of the ring. According to an exemplary embodiment of the insert ring was used as an elastic material for the ring part over the cross or cord fabric inserts as a uniform soft rubber.

   It has now been found that the flexing movement of the rubber in the pulley groove causes wear to occur on the flanks of the insert ring, which leads to premature destruction of the ring itself.



  The purpose of the additional invention is to prevent the wear on the ring flanks destroying the ring. According to the invention, an intermediate layer of harder, elastic, also oil-resistant material is provided between the cross or cord fabrics of the inner ring part and an outer ring part made of elastic material.



  In the drawing, an exemplary embodiment of the insert ring according to the invention is illustrated in cross section.



  The insert ring for split pulleys consists of an inner ring part with several cross or cord fabric layers 1, an intermediate layer 2 made of a harder elastic, oil-resistant material, for example a corresponding rubber mixture, and the outer ring part 3 made of softer, elastic, oil-resistant material, for example Soft rubber, together. The harder intermediate layer 2 greatly reduces the harmful effect of flexing and thus significantly extends the service life of the insert ring.
