Description

Der Erfindung liegt die Aufgabe zugrunde, die Lauffläche des Außenrings eines Lagers mittels einer Kugel einzuwalzen. Zu diesem Zweck dient eine Vorrichtung, die im wesentlichen aus einer unter Druck gegen eine Gleitbahn bewegbaren gabelförmigen Haltevorrichtung und einer mittels einer Achse, die durch die Gabel gehalten wird, geführten Kugel besteht. Über die Kugel ist der Außenring, dessen Lauffläche eingewalzt werden soll, geschoben, so daß also die Kugel in der Bohrung des Außenrings liegt und damit Kugel und Außenring zwischen der Gabel. Die Kugel ist beiderseitig entsprechend der Dicke des Außenrings abgeflacht, so daß die Kugel und der Außenring von der Gabel der Haltevorrichtung seitlich unverrückbar festgehalten werden können. Der Außenring ragt über die Gabel hinaus, so daß bei einer Führung des Außenrings mittels der Haltevorrichtung über eine Gleitbahn bei Anwendung von Druck eine der Rundung. der Kugel entsprechende Lauffläche in den Außenring eingewalzt wird. ' Eine beispielsweise Ausführungsform der Erfindung ist in der Zeichnung dargestellt.The invention is based on the object, the running surface of the outer ring rolling in a bearing by means of a ball. A device is used for this purpose, which essentially consist of a fork-shaped which can be moved under pressure against a slideway Holding device and one by means of an axis which is held by the fork, guided ball. The outer ring with its running surface is rolled over the ball is to be pushed so that the ball lies in the bore of the outer ring and thus the ball and the outer ring between the fork. The ball is mutually equivalent the thickness of the outer ring flattened so that the ball and the outer ring of the Fork of the holding device can be held laterally immovable. Of the Outer ring protrudes beyond the fork, so that when the outer ring is guided by means of the holding device over a slideway when applying pressure one of the rounding. The running surface corresponding to the ball is rolled into the outer ring. 'One for example Embodiment of the invention is shown in the drawing.

Es bedeutet: a eine gabelförmige Haltevorrichtung, b eine beiderseitig abgeflachte Kugel, c die Achse der Kugel, die durch die Gabel der Haltevorrichtung geht, d einen Außenring (Abb. z), e eine Gleitbahn und g einen Ring, in welchen der Außenring d vor dem Einwalzen der Lauffläche eingelegt wird.It means: a a fork-shaped holding device, b one on both sides flattened ball, c the axis of the ball passing through the fork of the holding device goes, d an outer ring (Fig. z), e a slideway and g a ring in which the outer ring d is inserted before the rolling surface is rolled in.

Wie aus der Zeichnung ersichtlich, ist eine Lauffläche in den Außenring d eingewalzt; dies geschieht durch die Kugel b, wenn die Haltevorrichtung a unter Druck über die Gleitfläche e bewegt wird. Wenn die Gleitbahn eben ist, wird die Haltevorrichtung hin und her bewegt; wenn die Gleitbahn als drehbarer Zylinder ausgebildet ist, wird die Haltevorrichtung und/oder die zylinderförmige Gleitbahn gedreht. Gemäß der Zeichnung sind über die Achse c der Kugel b noch zwei gehärtete Stahlscheiben f' und f" geschoben, die fest an der gabelförmigen Haltevorrichtung a bzw. an der abgeflachten Kugel b und dem Außenring anliegen, aber sich drehen können. An Stelle der Scheiben können seitliche Walzdrucklager dienen, die lose angesetzt oder auch vorgespannt sind. Wenn trotz dieser Vorkehrungen beim Auswalzen der Lagerfläche seitliche Ausbuchtungen des Lagerringsd' zur Achse hin auftreten, wie aus Abb. 2 ersichtlich, dann empfiehlt es sich, den Lagerring d" vor dem Auswalzen gemäß Abb. 3 zur Achse hin beizuholen. Beim Einwalzen der Lauffläche tritt dann wieder ein Ausgleich der Wandstärke ein.As can be seen from the drawing, a running surface is rolled into the outer ring d; this is done by the ball b when the holding device a is moved under pressure over the sliding surface e. If the slide is flat, the holding device is moved back and forth; if the slide is designed as a rotatable cylinder, the holding device and / or the cylindrical slide is rotated. According to the drawing, two hardened steel disks f ' and f "are pushed over the axis c of the ball b , which rest firmly against the fork-shaped holding device a or the flattened ball b and the outer ring, but can rotate. Instead of the disks Lateral roller thrust bearings can be used that are loosely attached or preloaded. If, despite these precautions, lateral bulges of the bearing ring d 'occur towards the axis when rolling out the bearing surface, as can be seen in Fig. 2, then it is advisable to remove the bearing ring d "before rolling to be obtained towards the axis according to Fig. 3. When the running surface is rolled in, the wall thickness is compensated for again.
