KLASSE 47b. GRUPPE 12.CLASS 47b. GROUP 12.

. ARTHUR KUHN in BERLIN. . Schraubenförmig bis. zu den Enden geschlitzte, hohle Tragrolle für Rollenlager. Patentiert im Deutschen Reiche vom 20. Februar 1912 ab.. ARTHUR KUHN in BERLIN. . Helical to. Hollow roller for roller bearings with slotted ends. Patented in the German Empire on February 20, 1912.

Die Erfindung betrifft schraubenförmig bis zu den Enden geschlitzte, hohle Tragrollen für Rollenlager. Der Erfindung gemäi3 sind die Enden des die Rollen bildenden Schraubenkörpers nach innen abgebogen und vorteilhaft abgerundet. Dadurch werden die nach längerem Gebrauch der Rollen bei den bekannten Rollenformen sich bildenden scharfen Kanten und Ecken vermieden. Diese scharfen Kanten und Ecken verursachen häufig ein Festsetzen der Rollen in den Lagern und infolgedessen die Wirkungslosigkeit der Rollen und ihre Zerstörung. · The invention relates to helical up to Hollow support rollers with slotted ends for roller bearings. According to the invention are the ends of the screw body forming the rollers bent inwards and advantageously rounded. This eliminates the sharp edges and sharp edges that are formed after prolonged use of the rollers in the known roller shapes Avoided corners. These sharp edges and corners often cause the Roles in the camps and, as a result, the ineffectiveness of the roles and their destruction. ·

Auf der Zeichnung ist eine Ausführungsform der Erfindung dargestellt. Fig. ι zeigt die Seitenansicht, Fig. 2 eine Stirnansicht einer Rolle. Die Wandung des spiralförmig aufgeschlitzten Rohres α ist an ihren Enden b nach innen gebogen, derart, daß das Ende ungefähr in die Mitte des Rohres zu liegen kommt. Die Enden sind abgerundet.An embodiment of the invention is shown in the drawing. Fig. Ι shows the side view, Fig. 2 shows an end view of a roller. The wall of the spirally slit tube α is bent inwards at its ends b , in such a way that the end comes to lie approximately in the middle of the tube. The ends are rounded.
