    Kugellager-Leerlaufnabe.   



   Der Gegenstand der Erfindung betrifft eine Nabe für   Leerlaufscheiben,   Leitrollen. Spannrollen u. dgl., die die Verwendung von offenen Kugellagern (sogenannten   Einschulterlagern)   gestattet. 



   Bei den bisher bekannten Kugellagernaben werden sogenannte geschlossene Laufringsysteme verwendet, die infolge der grossen Herstellungsgenauigkeit für die oben angeführten Zwecke, bei denen ein Bedürfnis an Genauigkeit in Längsrichtung nicht vorliegt, zu teuer sind ; der Einbau von den bekannten Einschulterlagern stösst wegen der Abstandhaltung der Lager und wegen der Gefahr von Verklemmungen auf Schwierigkeiten. Gemäss der Erfindung kommen offene Kugellager, die zwecks Vermeidung von Verklemmungen mit der bekannten sphärischen Laufbahn am Aussenring versehen sind, zur Anwendung, und sind die Aussen-oder Innenlaufringe durch ein elastisches, den auftretenden Druckwirkungen pro-   portional gehaltenes Zwischenglied (Schraubenfeder od. dgl. ) in Abstand gehalten.   



   Die Zeichnung zeigt eine beispielsweise Ausführungsform der Erfindung. In dem Gehäuse 1 sind die beiden sphärischen Aussenlaufringe 2 und 2a eingelegt. Der Laufring 2 stützt sich gegen die Stirnwand des Gehäuses ab ; der Laufring 2a wird durch Einschrauben des   Absehlussdeekels     4   auf die Kugelreihe aufgezogen, wobei die zwischen den Laufringen sich befindliche Schraubenfeder 5 zusammengedrückt wird ; infolge der Druckwirkung der Feder werden die beiden Laufringe in Abstand sowie der Abschlussdeckel   4   sicher in seiner Lage gehalten.

    Ball bearing idle hub.



   The subject of the invention relates to a hub for idler pulleys, guide rollers. Tension pulleys u. Like. That allows the use of open ball bearings (so-called one-shoulder bearings).



   In the ball bearing hubs known so far, so-called closed raceway systems are used, which are too expensive due to the great manufacturing accuracy for the above-mentioned purposes, in which there is no need for accuracy in the longitudinal direction; the installation of the known one-shoulder bearings encounters difficulties because of the spacing of the bearings and because of the risk of jamming. According to the invention, open ball bearings, which are provided with the known spherical raceway on the outer ring in order to avoid jamming, are used, and the outer or inner races are supported by an elastic intermediate member (helical spring or the like) that is held in proportion to the pressure effects. ) kept at a distance.



   The drawing shows an exemplary embodiment of the invention. In the housing 1, the two spherical outer races 2 and 2a are inserted. The race 2 is supported against the end wall of the housing; the race 2a is pulled onto the row of balls by screwing in the cover plate 4, the helical spring 5 located between the races being compressed; As a result of the pressure effect of the spring, the two races are kept at a distance and the cover 4 is held securely in place.
