Description

Rollenlager.
Die Erfindung betrifft eine Verbesserung und weitere Ausgestaltung des Rollenlagers gemäss
Patent Nr. 98841. Bei dem Stammpatent legen sich die Rollen mit kugelig gewölbten Enddruckflächen gegen konische Enddruckflächen der Laufring. Dieselbe Wirkung wie bei dem Stammpatent wird gemäss der vorliegenden Zusatzerfindung dadurch erreicht, dass die Enddruckflächen an den Rollen nicht kugelig, sondern kegelig und die Schultern an den Laufringen konvex oder konkav gewölbt ausgebildet sind.
Die kegelige Ausbildung hat den Vorteil, dass die Endflächen an den Rollen wesentlich leichter als kugelige herzustellen sind. Ferner wird durch die Anordnung gemäss der vorliegenden Erfindung erreicht, dass die Berührung zwischen den Rollen und den Laufringen möglichst lange auf einer Linie und nicht auf einer
Fläche erfolgt. Diese Fläche nimmt mit dem Verschleiss an Breite zu. Bildet man nun z. B. die Berührungstellen an den Ringen stark konvex aus, so muss auch bei eintretendem Verschleiss die Breite der Berührungs- fläche um so kleiner bleiben, und es wird infolgedessen die Reibung um so geringer, je stärker die Berührung- fläche am Ring konvex gewölbt ist.
Die Erfindung ist auf der Zeichnung in zwei Figuren dargestellt. Bei beiden Ausfuhrungs- beispielen sind die Endflächen der Rollen kegelig ausgebildet ; bei der Ausführungsform nach Fig. 1 sind die Enddruckflächen der Laufringe konvex und bei Fig. 2 konkav ausgebildet.

Roller bearings.
The invention relates to an improvement and a further embodiment of the roller bearing according to
Patent No. 98841. In the parent patent, the rollers with spherically curved end pressure surfaces lie against conical end pressure surfaces of the raceway. The same effect as in the parent patent is achieved according to the present additional invention in that the end pressure surfaces on the rollers are not spherical but conical and the shoulders on the raceways are convex or concave.
The conical design has the advantage that the end surfaces on the rollers are much easier to manufacture than spherical ones. Furthermore, it is achieved by the arrangement according to the present invention that the contact between the rollers and the races as long as possible on a line and not on one
Area takes place. This area increases in width with wear. If you now z. If, for example, the contact points on the rings are strongly convex, the width of the contact surface must remain smaller even if wear occurs, and the more the contact surface on the ring is convex, the lower the friction.
The invention is shown in the drawing in two figures. In both exemplary embodiments, the end surfaces of the rollers are conical; In the embodiment according to FIG. 1, the end pressure surfaces of the races are convex and in FIG. 2 they are concave.
