  Kugellager. 
 EMI1.1 
 verbundenes starkes Verschleissen eines dichten Abschlusses nach aussen. Man hat zu diesem Zweck bisher zwischen dem Kugellager und dem   Gehäuse oder   einem Widerlager Abdichtungs- 
 EMI1.2 
 Flächen gepresst wird. Dieser axiale Druck tritt naturgemäss auf beiden Seiten des Dichtungmaterials auf und es hängt lediglich von den an diesen Seiten herrschenden Reibungsverhältnissen ab, ob der   Dichtungskörper   feststeht oder von dem umlaufenden Teil des Kugellagers oder vom   Widerlager mitgenommen wird.   In allen Fällen schleift der Dichtungskörper an einem Teil des Kugellagers oder am Widerlager, und es findet ein baldiges Unbrauchbarwerden bzw.

   ein starker   Verschleiss der Dichtung   statt,   was einen häufigen   Ersatz derselben erfordert und andere Unzuträglichkeiten zur Folge hat. 



   Ganz besonders treten diese   mängel   bei Fahrradkugellagern in   Erscheinung,   für die eine dauernd gute öl-und staubsichere Abdichtung von ausschlaggebender Bedeutung ist. 



   Gemäss der Erfindung werden diese Nachteile dadurch vermieden, dass der Dichtungskörper nur an den einen Teil des Kugellagers (den umlaufenden oder den feststehenden) angedrückt und zwischen   Dichtungskörper und Widerlager   ein   Stützkugellager angeordnet wird. Dadur h   wird die Reibung zwischen Dichtungskörper und Widerlagei   wesentlich vermindert, so dass sich   
 EMI1.3 
 fast völlig entlastet wird, so behält er auch dauernd seine für die   Abdichtung wertvollen   Eigenschaften. 



   In   der   Zeichnung ist die Erfindung beispielsweise in anwendung bei einem Tret kurbellager mit   konzentrischen Laufringen in einer teilweisen Schnhtügur dargestellt.

  Ball-bearing.
 EMI1.1
 associated heavy wear and tear of a tight seal to the outside. For this purpose, sealing has so far been used between the ball bearing and the housing or an abutment
 EMI1.2
 Surfaces is pressed. This axial pressure naturally occurs on both sides of the sealing material and it depends only on the friction conditions prevailing on these sides whether the sealing body is stationary or is carried along by the rotating part of the ball bearing or by the abutment. In all cases, the sealing body rubs against part of the ball bearing or the abutment, and it soon becomes unusable or becomes unusable.

   a strong wear of the seal instead, which requires frequent replacement of the same and other inconveniences result.



   These deficiencies are particularly evident in bicycle ball bearings, for which a permanently good oil- and dust-proof seal is of decisive importance.



   According to the invention, these disadvantages are avoided in that the sealing body is only pressed against one part of the ball bearing (the rotating or the stationary) and a supporting ball bearing is arranged between the sealing body and the abutment. As a result, the friction between the sealing body and the abutment is significantly reduced, so that
 EMI1.3
 is almost completely relieved, it also permanently retains its properties that are valuable for sealing.



   In the drawing, the invention is shown for example in use with a pedal crank bearing with concentric races in a partial Schnhtügur.
