Description

Einstellvorrichtung für nachstellbare Wälzlager. Der Erfindungsgegenstand betrifft eine Einstellvorrichtung für nachstellbare Wälzlager (Kegelrollenlager, Schräg- und Schulterkugellager, Längskugellager u. dgl.). Nach-; steilbare Wälzlager werden bisher mittels Gewindemuttern nach dem Gefühle eingestellt; das richtige Einstellen bleibt dabei der Erfahrung und Geschicklichkeit des Einstellers überlassen. Häufig kommt es dabei vor, daß die Wälzlager zu fest angepreßt werden, sich vorzeitig abnutzen und schadhaft werden, oder aber zu locker eingestellt sind.Adjustment device for adjustable roller bearings. The subject of the invention relates to an adjustment device for adjustable roller bearings (tapered roller bearings, Angular contact and shoulder ball bearings, longitudinal ball bearings and the like). To-; adjustable rolling bearings are so far adjusted by means of threaded nuts according to the feeling; the right thing Setting is left to the experience and skill of the person setting it up. It often happens that the roller bearings are pressed too tightly, prematurely wear out and become damaged, or are set too loosely.

Es sind auch Einrichtungen bekannt, bei denen durch den Axialdruck einer gespannten Feder die Wälzlager selbsttätig in ihre Laufbahnen gedrückt werden. - Hierbei entsteht jedoch der Nachteil, daß die Wälzlager dauernd der Axialbelastung durch den Federdruck ausgesetzt sind.There are also devices known in which by the axial pressure a tensioned spring, the roller bearings are automatically pressed into their raceways. - Here, however, the disadvantage arises that the roller bearings are constantly subjected to the axial load are exposed to the spring pressure.

Bezweckt wird, das Ein- und Nachstellen der Wälzlager, ohne Axialbelastung durch Federdruck, unabhängig von der Geschicklichkeit des Einstellers zu machen. Erreicht wird dieser Zweck dadurch, daß beim Einstellen der Wälzlager durch selbsttätiges Einschalten einer Kupplung die Einstellmutter blockiert wird.The aim is to adjust and readjust the rolling bearings without any axial load by spring pressure, regardless of the skill of the adjuster. This purpose is achieved in that when adjusting the roller bearings by automatic Switching on a clutch the adjusting nut is blocked.

In der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes dargestellt. Es zeigt Abb. i die in eine Nabe eingebaute Anordnung vor dem Einstellen, Abb. 2 nach erfolgter Einstellung; Abb. 3 zeigt einen Schnitt A-B von Abb. 2, Abb. q. die Form der Kupplungszähne, Abb. 5 einen Schnitt C-D von Abb, i.In the drawing is an embodiment of the subject matter of the invention shown. Fig. I shows the arrangement built into a hub before adjustment, Fig. 2 after setting; Fig. 3 shows a section A-B from Fig. 2, Fig. q. the shape of the coupling teeth, Fig. 5 a section C-D of Fig, i.

a ist die Achse, b die Nabe, c die nachstellbaren Kegelrollenlager, d eine Einstellmutter mit Splintsicherung. An der Einstellmutter d ist eine Zahnkupplung e mit Zähnen f befestigt. Ein Kuppelkonus g mit Zähnen h ist auf der Achse a längsverschiebbar, aber durch die Nasen i in den Nuten k undrehbar angeordnet. Die Einstellmutter d besitzt eine über den Kuppelkonus g greifende rohrförmige Verlängerung L und trägt die Stahldrahtfeder -izz. Letztere ragt an zwei durchbrochenen Stellen des Rohres l hindurch und drückt auf die kegeligen Außenflächen n, o des Kuppelkonus g. p ist eine vor dem Einstellen kegelige Stahlblechscheibe zwischen Wälzlager und Einstellmutter d. Die Wirkungsweise ist folgende: In der Lage der Teile, wie in Abb. i ersichtlich, wird die Einstellmutter d in bekannter Weise aufgeschraubt; die Feder in und die Stahlblechscheibe p drücken zunächst die Wälzlager c-gegeneinander, bis kein Spielraum mehr vorhanden ist. Beim Weiterdrehen der Einstellmutter d steigt die Feder m an der inneren Kegelfläche .n des Kuppelkonus auf, bis dessen größter Durchmesser überschritten ist. Dann drückt die Feder in auf die äußere Kegelfläche o, der Kuppelkonus kippt nach der Zahnkupplung e zu, die Zähne f, h greifen ineinander und verhindern die Einstellmutter, d am Weiterdrehen. Gleichzeitig mit dem Umkippen bzw. Verschieben des Kuppelkonus schnappt auch die Stahlblechscheibe in die Form einer geraden Planscheibe, wie in Abb.2 ersichtlich. Nach rückwärts kann die Mutter d gedreht werden, so daß ein Splint in das Splintloch q eingesetzt und auch die Anordnung abgeschraubt und neu eingestellt werden kann.a is the axle, b the hub, c the adjustable tapered roller bearings, d an adjusting nut with cotter pin lock. A toothed clutch e with teeth f is attached to the adjusting nut d. A coupling cone g with teeth h is longitudinally displaceable on the axis a, but is arranged non-rotatably in the grooves k due to the lugs i. The adjusting nut d has a tubular extension L reaching over the coupling cone g and carries the steel wire spring -izz. The latter protrudes through two perforated points of the tube l and presses on the conical outer surfaces n, o of the coupling cone g. p is a conical sheet steel washer between the roller bearing and the adjusting nut d. The mode of operation is as follows: In the position of the parts, as can be seen in Fig. I, the adjusting nut d is screwed on in a known manner; the spring in and the sheet steel washer p first press the roller bearings c-against each other until there is no longer any leeway. As the adjusting nut d continues to be turned , the spring m rises on the inner conical surface .n of the dome cone until its largest diameter is exceeded. Then the spring presses in on the outer conical surface o, the coupling cone tilts towards the tooth coupling e, the teeth f, h interlock and prevent the adjusting nut, d from turning further. At the same time as the coupling cone is tipped over or moved, the sheet steel disk also snaps into the shape of a straight face disk, as can be seen in Fig. The nut d can be turned backwards so that a cotter pin can be inserted into the cotter pin hole q and the arrangement can also be unscrewed and readjusted.
