Description

Die Erfindung betrifft ein elastisches Lager, und zwar eine dem sogenannten Nadellager verwandte Ausführung desselben.The invention relates to an elastic bearing, namely one of the so-called Needle roller bearing related version of the same.

Es ist bekannt, bei Rollenlagern die Rollen als zylindrische Schraubenfedern von rechteckigem Querschnitt auszubilden, wobei die einzelnenFederrollen von einem durchgehenden Käfigbolzen geführt werden. Im Belastungsfalle geben dieseRollen zwar in radialer Richtung nach. Möglich ist dies aber nur, wenn die Rolle gleichzeitig in axialer Richtung gespannt wird. Auf Grund der hierdurch an den Seitenscheiben eines solchen Lagers auftretenden Reibungskräfte ist man von Lagern der genannten Art dann wieder abgekommen.It is known that in roller bearings, the rollers take the form of cylindrical helical springs of rectangular cross-section, the individual spring rollers from one through cage bolts are guided. In the case of stress, these roles do in the radial direction. But this is only possible if the role is at the same time is tensioned in the axial direction. Because of this on the side windows Frictional forces occurring in such a bearing are one of the bearings mentioned Kind of then strayed again.

Die Erfindung besteht demgegenüber darin, daß die Nadeln bzw. Rollen des Lagers als Spannstifte ausgebildet sind.The invention consists in the fact that the needles or rollers of the bearing are designed as dowel pins.

Als besonders geeignet erweisen sich für diesen Zweck Spannstifte, deren Schlitze schraubenförmig geführt und- deren Enden abgerundet sind. Insbesondere bei Lagern für große spezifische Belastungen werden in den zwischen den Spannstiften einerseits und dem Lagerring bzw. der Achse, Bolzen o. dgl. andererseits gebildeten Hohlräumen weitere Spannstifte angeordnet.Dowel pins prove to be particularly suitable for this purpose, whose slots are helically guided and whose ends are rounded. In particular in the case of bearings for large specific loads, there are between the dowel pins on the one hand and the bearing ring or the axle, bolt or the like. On the other hand formed Cavities further dowel pins arranged.

Zur Veranschaulichung der Erfindung zeigen in beispielsweiser Ausführung Abb. i ein Lager in Ansicht von der Seite, wobei im Interesse der Deutlichkeit von den Seitenscheiben des Lagers nur der äußere Umfang angedeutet ist, Abb. 2 einen Schnitt nach der Linie 2-2 in Abb. i und Abb. 3 bis 5 einen Spannstift im Grundriß, Aufriß und Längsschnitt in gegenüber den Abb. i und 2 vergrößertem Maßstabe.To illustrate the invention show in an exemplary embodiment Fig. I A bearing in side view, with in the interest of clarity of the side plates of the bearing only the outer circumference is indicated, Fig. 2 a Section along the line 2-2 in Fig. I and Fig. 3 to 5 a roll pin in plan, Front elevation and longitudinal section on an enlarged scale compared to Figs. I and 2.

Zwischen einem Lagerring io und einer als Hohlwelle ausgebildeten Welle i i sind Spannstifte 12 angeordnet. Die Spannstifte sind mit einem Längsschlitz 13 versehen, welcher sich schraubenförmig von dem einen Ende 14 des Lagers nach dem anderen Ende 15 hinzieht. An den Enden 14, 15 sind die Spannstifte 12 abgerundet, so daß die Reibung an den Seitenscheiben 16 auf ein Mindestmaß beschränkt wird. Bei Lagern mit besonders hoher spezifischer Belastung werden in den Hohlräumen 17, 18, die im Querschnitt einander mit den Spitzen berührende, ähnliche sphärische Dreiecke darstellen, wie in Abb. i angedeutet, weitere Spannstifte 7, 8 angeordnet. Dieselben sind gegebenenfalls wie Lagernadeln bekannter Art ausgebildet.Between a bearing ring and one designed as a hollow shaft Dowel pins 12 are arranged on shaft i i. The dowel pins have a longitudinal slot 13 provided, which is helical from one end 14 of the bearing to the other end 15 pulls. At the ends 14, 15 the dowel pins 12 are rounded, so that the friction on the side windows 16 is limited to a minimum. In the case of bearings with a particularly high specific load, cavities 17, 18, the similar spherical one in cross section touching one another with the tips Represent triangles, as indicated in Fig. I, further dowel pins 7, 8 arranged. The same are optionally designed as bearing needles of a known type.

Die Abb.3 bis 5 lassen einen Spannstift für elastische Lager von Preßwalzen, Kranen u. dgl. erkennen. Der Spannstift 2o entspricht, abgesehen von der Größe, in Form und Ausführung den in den Abb. i und 2 dargestellten Spannstiften 12.Figures 3 to 5 show a dowel pin for elastic bearings on press rolls, Recognize cranes and the like. The roll pin 2o corresponds, apart from the size, the dowel pins 12 shown in Figs. i and 2 in terms of shape and design.

Wird ein Lager der beschriebenen Art von der Achse oder dem Lagerring her belastet, so wird die Belastung von den Spannstiften elastisch auf die Gegendruck haltende Seite des Lagers übertragen. Führt man die Spannstifte mit leichter' Vorspannung in das Lager ein, so entspricht der Durchmesserverkleinerung der gepreßten Spannstifte auf der einen Seite eine Vergrößerung des Durchmessers der entlasteten Spannstifte auf der gegenüberliegenden Seite des Lagers. Die Welle wird also in jedem Falle allseitig geführt. Durch die Hohlräume des Lagers und der Spannstifte können beliebig große Schmierstoffmengen gefördert werden, so daß das Lager bei jeder Belastung ausreichend geschmiert und gekühlt wird.If a bearing of the type described is used by the axle or the bearing ring loaded, the load from the dowel pins is elastic on the counter pressure transferring the holding side of the bearing. If you guide the dowel pins with a slight 'pretension into the bearing, then corresponds to the reduction in diameter of the pressed dowel pins on the one hand an enlargement of the diameter of the relieved spring pins on the opposite side of the camp. So the wave will in any case guided on all sides. Through the cavities of the bearing and the dowel pins, any large quantities of lubricant are conveyed, so that the bearing is exposed to any load is adequately lubricated and cooled.
