Drucklager mit getrennt voneinander gehaltenen Kugeln sind an sich bekannt. Desgleichen ist es bekannt, die Trennung dieser tragenden Kugeln durch kleinere mitlaufende Zwischenkugeln zu bewerkstelligen, indem diese kleineren Kugeln einfach seitwärts zwischen die Tragkugeln gelegt werden, und zwar so, daß ihre Laufbahn sich auf einem der beiden Druckringe unmittelbar befindet.
ίο Das Wesentliche der Erfindung besteht nun darin, daß die kleinen Zwischenkugeln keinen der beiden Lagerteile unmittelbar berühren, sondern daß sie in einer besonderen Führungsrille laufe.n. Hierdurch wird bei richtiger Bemessung der Kugeldurchrnesser und der übrigen Teile des Lagers erreicht, daß jedes Gleiten zwischen den Kugeln oder zwischen sonst sich berührenden Punkten des Lagers ausgeschlossen, vielmehr an allen Teilen des Lagers nur rollende Reibung vorhanden ist.
Thrust bearings with balls held separately from one another are known per se. Likewise, it is known to accomplish the separation of these supporting balls by smaller accompanying intermediate balls by simply placing these smaller balls sideways between the supporting balls in such a way that their raceway is directly on one of the two pressure rings.
ίο The essence of the invention is that the small intermediate balls do not touch either of the two bearing parts directly, but that they run in a special guide groove. If the ball diameter and the other parts of the bearing are correctly dimensioned, this ensures that any sliding between the balls or between otherwise contacting points of the bearing is ruled out; rather, there is only rolling friction on all parts of the bearing.

Der Erfindungsgegenstand ist durch die Zeichnung in einer Ausführungsform dargestellt. The subject matter of the invention is shown in one embodiment by the drawing.

Fig. ι zeigt ein gemäß der Erfindung ausgeführtes Drucklager im Schnitt.Fig. Ι shows a carried out according to the invention Thrust bearing in section.

Fig. 3 eine teilweise Seitenansicht.Fig. 3 is a partial side view.

Zwischen dem oberen Druckring α und dem unteren Druckring b sind in bekannter Weise die Kugeln c eingeschaltet. Zwischen den Tragkugeln c sind kleinere Kugeln d angeordnet, welche durch eine mit Rille' f versehene Führungshülse g so gehalten werden, daß die Drehungsachse der Tragkugeln c oder deren Verlängerung zwischen den kleineren Kugeln, d einerseits und der Laufbahn desjenigen Druckringes anderseits zu liegen kommt, mit dem die Führungshülse g fest verbunden ist.Between the upper pressure ring α and the lower pressure ring b , the balls c are switched on in a known manner. Between the supporting balls c , smaller balls d are arranged, which are held by a guide sleeve g provided with a groove 'f so that the axis of rotation of the supporting balls c or its extension comes to lie between the smaller balls d on the one hand and the raceway of that pressure ring on the other, with which the guide sleeve g is firmly connected.

Angenommen, der obere Ring α stehe fest und der untere Ring b laufe von rechts nach links um. Es werden dann die Tragkugeln c in der gleichen Richtung mitgenommen, und jede der kleinen Zwischenkugeln d befindet sich dann jenseits der Drehungsachse α α der Tragkugeln c, berührt aber trotzdem nicht den oberen Druckring a, da die mit b fest verbundene Hülse.g sie davon abhält. Die Zwischenkugeln d drehen sich also entgegengesetzt zu den Tragkugeln c, werden jedoch trotzdem von den nach links laufenden Kugeln c mitgenommen.Assume that the upper ring α is stationary and the lower ring b revolves from right to left. The supporting balls c are then taken along in the same direction, and each of the small intermediate balls d is then on the other side of the axis of rotation α α of the supporting balls c, but still does not touch the upper pressure ring a, since the sleeve firmly connected to b. g prevents them from doing so. The intermediate balls d rotate in the opposite direction to the supporting balls c, but are nevertheless carried along by the balls c running to the left.

Wie ohne weiteres ersichtlich, würde große Reibung entstehen, wenn die Zwischenkugeln d mit dem Ring α in Berührung ständen, was gemäß der Erfindung vermieden wird.As is readily apparent, great friction would arise if the intermediate balls d were in contact with the ring α , which is avoided according to the invention.

Es wird also die Bewegung der aneinander gleitenden Teile dadurch unterstützt, daß dieSo it is the movement of the sliding parts supported by the fact that the

Führungshülse g an dem unteren Ring b befestigt ist, so daß sie mit diesem Ring in gleicher Richtung umläuft.Guide sleeve g is attached to the lower ring b so that it rotates with this ring in the same direction.

Claims (1)

Patent-Anspruch :Patent claim: Drucklager mit zwischen den Tragkugeln mitumlaufenden Zwischenstücken (Kugeln, Rollen o. dgl.), dadurch gekennzeichnet, 'daß diese Zwischenstücke durch eine Führung so gehalten werden, daß die Drehungsachse der Tragkugeln (c) oder deren Verlängerung zwischen den Zwischenstücken einerseits und der Laufbahn desjenigen Druckringes anderseits zu liegen kommt, mit dem die Führung verbunden ist.Thrust bearing with intermediate pieces (balls, rollers or the like) rotating between the supporting balls, characterized in that these intermediate pieces are held by a guide in such a way that the axis of rotation of the supporting balls (c) or its extension between the intermediate pieces on the one hand and the track of that Pressure ring comes to rest on the other hand, with which the guide is connected.
