Description

  

      Tretkurbellager    für Fahrräder.    Die vorliegende Erfindung betrifft ein       Tretkurbellager    für Fahrräder, das sich  durch leichteren Gang und     besonders    durch  höhere Belastungsfähigkeit auszeichnen soll  als die bekannten     Konuslager-    und Kugel  lager.  



  Gemäss der Erfindung weist     da-s        Tret-          kurbellager    wenigstens ein Walzenlager auf.  Um auch grössere     achsiale    Belastungen  aufnehmen zu können, sind die Laufflächen  für die Walzen     vorteilhafterweise    konisch  ausgebildet.  



  In der     Zeichnung    ist eine beispielsweise       Ausführungsform        des    Erfindungsgegenstan  des im     Aehsialschnitt    dargestellt.  



  In der     Tretlagermuffe    1 des Fahrrad  rahmens ist mittelst der Walzenlager 2, 3 die       Tretkurbelachse    4 gelagert. Die Walzen  verlaufen zur     Tretkurbelachseschräg.    Durch  die auf die     Stirnseiten    der Muffe 1 aufge  schraubten Schalen 5, 6 sind die Walzen  lager 2, 3 vor Staub geschützt. Die Lauf  ringe 2', 2" des Walzenlagers 2, sowie die       Laufringe    3', 3" des Walzenlagers 3 haben    konische Laufflächen. Während der Lauf  ring 3' des Walzenlagers 3 an der Achse 4  festsitzt, ist beim Walzenlager 2 der innere  Laufring 2'     mittelst    Gewinde 7 auf der  Achse 4 verstellbar gelagert.

   Dadurch ist es  möglich, die Walzenlager 2, 3 von Zeit zu  Zeit     nachzuspannen.    Die Stellung des Lauf  ringes 2' ist durch die Gegenmutter 8 ge  sichert.  



  In Fällen weniger hoher     Beanspruchung     des     Tretkurbellagers    können .die Laufringe  2', 2" und 3', 3" auch zylindrische     Lauf-          flächen    aufweisen. In diesem Falle sind die  Walzenlager nicht     nachspannbar    und .die  Walzen sind parallel zur     Tretkurbelachse    4  angeordnet. .



      Pedal crank bearings for bicycles. The present invention relates to a pedal crank bearing for bicycles, which is to be characterized by easier gear and especially by higher load capacity than the known cone bearings and ball bearings.



  According to the invention, the pedal crank bearing has at least one roller bearing. In order to be able to absorb larger axial loads, the running surfaces for the rollers are advantageously conical.



  In the drawing, an example embodiment of the subject matter of the invention is shown in the axial section.



  In the bottom bracket sleeve 1 of the bicycle frame, the crank axle 4 is mounted by means of the roller bearings 2, 3. The rollers run obliquely to the crank axle. By screwing up on the end faces of the sleeve 1 shells 5, 6, the rollers are bearings 2, 3 protected from dust. The race rings 2 ', 2 "of the roller bearing 2, and the races 3', 3" of the roller bearing 3 have conical running surfaces. While the running ring 3 'of the roller bearing 3 is firmly seated on the axis 4, the inner running ring 2' of the roller bearing 2 is adjustably supported by means of a thread 7 on the axis 4.

   This makes it possible to re-tension the roller bearings 2, 3 from time to time. The position of the running ring 2 'is secured by the lock nut 8 ge.



  In cases where the pedal crank bearing is not subjected to high loads, the races 2 ', 2 "and 3', 3" can also have cylindrical running surfaces. In this case the roller bearings cannot be re-tensioned and the rollers are arranged parallel to the crank axle 4. .
