  Rollenlager. 



   Vorliegende Erfindung betrifft ein Rollenlager, welches mit Rollen und Laufringen von solcher
Form ausgestattet ist, dass der   durch dielaufr ; nge auf   die Rollen ausgeübte Druck bestrebt ist, die Rollen in deren Achsenrichtung zu verschieben, und das mit an einem der Laufringe angeordnetem Druckflansch versehen ist, der dazu dient, eine solche Verschiebung der Rollen in axialer Richtung zu verhindern. Die . Erfindung verfolgt den Zweck, e-n Lager dieser Gattung zu schaffen, bei dem der Druckflansch gleich-   zeitig   als Führung für die Rollen dient, so dass diese verhindert werden, sich schräg einzustellen. 



   Die Erfindung besteht zu diesem Zweck in der Hauptsache darin, dass das gegen den Druckflansch anliegende Ende jeder   Rolle sphärische   Form hat mit dem Mittelpunkte der Kugel im Schnittpunkt zwischen der Rollenachse und der Lagerachse und dass die   Anlagefläche   des Druckflansches solche Form hat, dass die Berührung zwischen den genannten Flächen längs einer Fläche oder einer Linie stattfindet, die sich in der Richtung des Rollens erstreckt. Hiedurch wird eine gute Führung der Rollen, ohne dass ein besonderer Führungsflansch zu diesem Zweck angeordnet zu werden braucht, und somit auch eine wesentliche Vereinfachung des Lagers erzielt.

   Der Druckflansch kann dabei entweder mit einer sphärischen Anlagefläche, die der sphärischen   Endfläche   jeder Rolle entspricht und gegen die die genannte Endfläche so anliegt, dass die Berührung zwischen beiden längs einer Fläehe stattfindet, oder auch mit einer kegelförmigen   Anlagefläche,   deren Spitze in der Lagerachse liegt, versehen sein, gegen die die sphärische
Endfläche jeder Rolle so anliegt, dass die Berührung zwischen beiden Flächen längs einer Linie stattfindet, die die Richtung des Rollens hat.

   Der   Druckflansch   1 kann auch an dem Aussenring 3 angeordnet werden ; er kann auch gesondert hergestellt sein und ist nur mit dem betreffenden Laufring so zu verbinden, dass er die Verschiebung der Rollen in deren Achsenrichtung verhindert. 



   PATENT-ANSPRÜCHE :

  Roller bearings.



   The present invention relates to a roller bearing, which with rollers and races of such
Shape is equipped that the through the run; The pressure exerted on the rollers tends to move the rollers in their axial direction, and which is provided with a pressure flange arranged on one of the races, which serves to prevent such a displacement of the rollers in the axial direction. The . The invention pursues the purpose of creating a bearing of this type in which the pressure flange also serves as a guide for the rollers, so that they are prevented from adjusting at an angle.



   For this purpose, the invention consists mainly in the fact that the end of each roller resting against the pressure flange has a spherical shape with the center of the ball at the point of intersection between the roller axis and the bearing axis and that the contact surface of the pressure flange has such a shape that the contact between said surfaces takes place along a surface or line extending in the direction of rolling. This achieves good guidance of the rollers without the need for a special guide flange to be arranged for this purpose, and thus also a significant simplification of the bearing.

   The pressure flange can either have a spherical contact surface, which corresponds to the spherical end surface of each roller and against which the named end surface rests in such a way that the contact between the two takes place along a surface, or with a conical contact surface, the tip of which lies in the bearing axis, be provided against which the spherical
End face of each roller in such a way that the contact between the two faces takes place along a line which has the direction of the rolling.

   The pressure flange 1 can also be arranged on the outer ring 3; it can also be manufactured separately and only needs to be connected to the relevant race in such a way that it prevents the rollers from shifting in their axial direction.



   PATENT CLAIMS:
1. Roller bearings with rollers and races of such a shape that the pressure exerted by the races on the rollers tends to move the rollers in their axial direction and with a pressure flange arranged on one of the races, which prevents such a displacement of the rollers in the axial direction , characterized in that the end of each roller resting against the pressure flange has a spherical shape with the center point of the ball at the intersection between the roller axis and the bearing axis and that the contact surface of the pressure flange has such a shape that the contact between said surfaces along a surface or takes place in a line extending in the direction of the roll to prevent the rolls from tipping.
