Die Neuerung bezieht sich auf ein kombiniertes Radial-Axial-Nadellager, bestehend aus einem Radial-Nadellager mit in einem Käfig geführten Nadeln und einem aus Blech hergestellten Außenlaufring sowie aus einem Axial-Nadellager mit in einem Käfig geführten Nadeln und zwai aus Blech hergestellten Laufscheiben, wobei der Außenlaufring des Radial-Nadellagers einstückig mit einer Laufscheibe des Axial-Nadellagers ausgebildet ist.The innovation relates to a combined radial-axial needle roller bearing, consisting of a radial needle roller bearing with a cage Needles and an outer race made of sheet metal as well as one Axial needle roller bearings with needles guided in a cage and two made of sheet metal manufactured running disks, with the outer race of the radial needle bearing formed in one piece with a washer of the axial needle roller bearing is.
Es ist bereits ein kombiniertes Radial-Axial-Nadellager bekannt, bei dem der Außenlaufring des Radial-Nadellagers und die Laufscheibe des Axial-Nuuellagers in einem Stück aus Blech ausgeführt sind. Bei diesem Lager, das nur eine Laufscheibe besitzt, ist der Axialkilfig in keiner Weise L.it dem Lager verbunden und muß daher getrennt gehanc'habt werden, was den Transport und die Montage erschwert.A combined radial / axial needle roller bearing is already known the outer race of the radial needle roller bearing and the washer of the Axial Nuuelllager are made in one piece from sheet metal. With this one A bearing that only has one washer is not an axial thrust in any Wise L. connected to the camp and must therefore be handled separately, which makes transport and assembly difficult.
Bei einem anderen bekannten kombinierten Radial-Axial-Nadellager wird zwar der Axialkiifig durch einen am äußeren Umfang der Laufscheibe befestigten, den Rand des Käfigs umfassenden Ring gehalten, jedoch besitzt dieses Lager ebenfalls nur eine einzige Laufscheibe. Diese ist durch zusätzliche Befestigungsmittel mit dem Außenring des Radiallagers verbunden, wodurch die Herstellung dieses Lagers relativ teuer ist.In another known combined radial-axial needle roller bearing Although the Axialkiifig is attached to the outer circumference of the running disk, held the edge of the cage encompassing ring, but this bearing also has only a single washer. This is due to additional Fasteners connected to the outer ring of the radial bearing, making this bearing relatively expensive to manufacture.
Die Neuerung hat sich nun die Aufgabe gestellt, ein mit niedrigen Kosten aus Blech herstellbares kombiniertes Radial-Axial-Nadellager mit zwei Laufscheiben zn schaffen, das auf einfache Weise zu einer geschlossenen Baueinheit zusaiaiuengehalten wird. Diese Aufgabe wird dadurch gelöst, daß die lose Laufscheibe des Axialnadellagers in inrer Bohrung mit einem axial vorlaufenden, ringförmigen Kragen versehen ist, an dem mehrere gleichmäßig über den Umfang verteilte Vorsprünge ange-The innovation has now set itself the task of a combined radial-axial needle roller bearing that can be produced from sheet metal at low cost with two running disks zn create a closed one in a simple manner Building unit is held together. This object is achieved in that the loose washer of the axial needle bearing is inrer Bore is provided with an axially leading, annular collar, on which there are several projections evenly distributed over the circumference.

bracht sind, die in die Hingnut oder hinter den ringförmigen Absatz eines am inneren Umfang des Außenlaufrings des Radiallagers befestigten, mit einer Anlauffläche für den Radialkäfig versehenen Rings eingreifen. Durch diesen Ring werden einerseits der Radialkäfig und andererseits die lose Laufscheibe und damit auch der Axialkäfig in axialer Richtung gehalten, so daß das Lager eine geschlossene Baueinheit darstellt. Dazu ist der Außenring des Radiallagers zweckmäßigerweise an einem Ende mit einem radial .lach innen gerichteten Bord versehen und der Radialkäfig so ausgebildet, daß die Wälzkörper nicht radial nach innen herausfallen können. Der King kann aus Blech oder Kunststoff sein und wird durch Preßsitz im Außenring des Radiallagers befestigt. Bei geeigneter Formgebung kann der Ring mit zur Abdichtung des Lagers beitragen.are brought into the hanging groove or behind the annular shoulder one attached to the inner circumference of the outer race of the radial bearing, engage with a contact surface for the radial cage provided ring. Through this ring on the one hand the radial cage and on the other hand the loose running disk and thus also the axial cage are held in the axial direction so that the bearing is a closed structural unit. In addition the outer ring of the radial bearing is expediently provided at one end with a radially .lach inwardly directed rim and the radial cage designed so that the rolling elements cannot fall out radially inward. The King can and will be made of sheet metal or plastic fastened by a press fit in the outer ring of the radial bearing. With a suitable shape, the ring can contribute to the sealing of the bearing.
Im folgenden werden mehrere Ausfuhrungsbeispiele der Neuerung anhand der Zeichnung näher erläutert. Es zeigenIn the following, several exemplary embodiments of the innovation are based on the drawing explained in more detail. Show it

Fig. 2 und 3 einen Toi!schnitt durch ein neuerungsgemäßes Lager mit anderen Ausführungen der Halterung.2 and 3 show a section through a bearing according to the invention with other versions of the bracket.
Der Außenring 1 für die in einem Käfig 2 geführten Nadeln 3 des Radiallagers eines kombinierten Lagers gemäß Fig. 1 ist an einem Ende mit einem radial nach innen gerichteten Bord 4 versehen und geht am anderen Ende in einen radial nach außen verlaufenden Flansch 5 über, der als Laufscheibe fur die im Käfig 6 geführten Nadeln 7 des Axiallagers dient und an seinem Ende den axial gerichteten Kragen 8 aufweist. Die lose Laufscheibe 9 ist in der Bohrung mit einem axial gerichteten Kragen 10 ausgestattet, an dem mehrere gleichmäßig über den Umfang verteilte Eindrückungen 11 vorgesehen sind. Diese Eindrückungen 11 greifen hinter den Absatz 12 eines in den Außenring 1 eingefügten Rings 13 aus Blech, der am anderen Ende einen radial nach innen gerichteten Bord 14 aufweist. Durch die Borde 4 und 14 wird der Käfig 2 axial geführt und durch den Absatz 12 wird die lose Laufscheibe 9 gehalten, so daß das Lager eine geschlossene Baueinheit bildet.The outer ring 1 for the needles 3 guided in a cage 2 of the radial bearing of a combined bearing according to FIG serves as a running disk for the needles 7 of the axial bearing guided in the cage 6 and has the axially directed collar 8 at its end. The loose running disk 9 is equipped in the bore with an axially directed collar 10 on which a plurality of indentations 11 distributed evenly over the circumference are provided. These indentations 11 engage behind the shoulder 12 of a ring 13 made of sheet metal which is inserted into the outer ring 1 and has a rim 14 directed radially inward at the other end. The cage 2 is axially guided by the rims 4 and 14 and the loose running disk 9 is held by the shoulder 12, so that the bearing forms a closed structural unit.

Der Ring 15 ist hier aus Kunststoff und ebenfalls mit einem Anlaufbord l6 für den Käfig 2 und einem Absatz 17 versehen.In Fig. 2 is another embodiment of the mounting of the loose washer shown. The ring 15 is here made of plastic and is also provided with a run-up rim l6 for the cage 2 and a shoulder 17.
Bei der Halterung nach Fig. 3 weist der Ring 18, der ebenfalls aus Kunststoff ist, einen Anlaufbord 19 und eine Ringnut 20 aui, in die nach außen gerichtete Eindrückungen 21 des axial verlaufenden Kragenr 10 eingreifen. Die Käfige 2, 6 sind hier aus Kunststoff.In the holder according to FIG. 3, the ring 18, which is also made of plastic is, a run-up rim 19 and an annular groove 20 aui, in the outward directed indentations 21 of the axially extending collar 10 engage. The cages 2, 6 are made of plastic here.
Die Neuerung ist nicht auf die gezeigten Beispiele beschränkt, sondern es sind noch andere konstruktive Abänderungen der Halterung denkbar.The innovation is not limited to the examples shown, but rather there are other design modifications of the bracket conceivable.
In jedem Falle biJJen die neuerungsgemäßen Lager eine geschlossene Baueinheit, die bei Bedarf ohne Zerstörung eines Lagerteils demontierbar ist und die relativ billig unter Verwendung gezogener Blechteile hergestellt werden kann.In any case, the bearings in accordance with the renewal are a closed structural unit, which can be dismantled if necessary without destroying a bearing part and which can be manufactured relatively cheaply using drawn sheet metal parts.
