Die vorliegende Neuerung hat ein Bollenlager, insbesondere ein Nadellager mit einem dünnwandigen Lagerring zum Gegenstand, der mit dem Wälzkörperkranz eine einbaufertige Einheit bildet.The present innovation has a ball bearing, in particular a needle bearing with a thin-walled bearing ring to the object that is connected to the Rolling element ring forms a ready-to-install unit.
Rollen- insbesondere Nadellager mit dünnwandigen, d. h. aus einer gezogenen Hülse bestehenden Außenringen sind bekannt. Bei diesen bekannten Ausführungen sind zur Halterung des Käfigs an beiden Enden radiale Borde angeordnet. Um den Käfig mit den Wälzkörpern einführen zu können, ist es bei diesen Lagern erforderlich, einen Bord erst nach dem Einführen umzulegen. Da jedoch die Hülsen im allgemeinen gehärtet werden müssen und ein Umbiegen des Hülsenendes im gehärteten Zustand nur unter großen Schwierigkeiten durchführbar ist, müssen beim Härten der Hülsen Vorkehrungen getroffen werden, daß dieses Ende ungehärtet bleibt. Diese Vorkehrungen sind einmal aufwendig und zum anderen muß entweder dieser Bord nachträglich gehärtet werden oder es muß in Kauf genommen werden, daß beim Anlauf des Käfigs an diesem ungehärteten Bord großer Verschleiß entsteht.Roller, in particular needle roller bearings with thin-walled, d. H. from a drawn Existing sleeve outer rings are known. In these known designs, radial ends are used to hold the cage Arranged shelves. In order to be able to introduce the cage with the rolling elements, with these bearings it is necessary to insert a shelf only after it has been inserted to kill. However, since the sleeves must be hardened in general and bending of the sleeve end in the hardened state only under great difficulty is feasible, precautions must be taken when hardening the sleeves that this end remains uncured. These On the one hand, precautions are time-consuming and, on the other hand, either this board must be subsequently hardened or it must be accepted, that when the cage starts up on this unhardened board, great wear occurs.
Zur Umgehung dieser Schwierigkeiten und zur Schaffung einer Lagereinheit, bestehend aus einem dünnwandigen Außenring und einem Bollen- bzw. Nadelkranz, wurde bereits vorgeschlagen, den Außenring lediglich mit einem radialen Bord zu versehen, der in eine Nut im Mantel des Käfigseitenringes eingreift. Die vorliegende Neuerung baut auf diesen Vorschlag auf und hat zum Ziel, diesen Vorschlag zu verbessern.To circumvent these difficulties and to create a storage unit, consisting of a thin-walled outer ring and a collar or needle ring, it has already been proposed to only provide the outer ring with a radial rim which is inserted into a groove in the jacket of the cage side ring intervenes. The present innovation builds on this proposal and aims to improve this proposal.
Zu diesem Zweck wird vorgeschlagen, den radialen Seitenbord mit einem zur Lagerachse geneigten, nach außen weisenden ringförmigen Ansatz zu versehen. Jurch diese Ausführung wird einmal erreicht, daß der Käfig mit dem Außenring eine Einheit bildet, zum anderen wird der Käfig gut geführt. Hinzu kommt noch, daß der Seitenbord verhältnismäßig steif wird, daß also die Gefahr des Aufbiegens bei axialen Kräften verringert wird.For this purpose, it is proposed that the radial side board with a to provide inclined to the bearing axis, outwardly facing annular projection. By doing this it is achieved that the cage forms a unit with the outer ring, on the other hand, the cage is well guided. In addition, the side board is relatively stiff is, that so the risk of bending is reduced with axial forces will.

Die Neuerung soll an dem in der beiliegenden Zeichnung dargestellten Ausführungsbeispiel näher beschrieben werden.The innovation should be based on the one shown in the accompanying drawing Embodiment will be described in more detail.
Der dünnwandige Außenring 1 weist einen radialen, spanlos angeformten Bord 2 auf, der an seineia freien Ende 3 einen zur Lagerachse geneigten, nach außen weisenden ringförmigen Ansatz 4 besitzt. Der Käfig 5 ist auf dem Mantel eines Seitenringes mit einer etwa v-förmigen Aussparung 6 versehen, in die der Seitenbord 2 mit seinem Ansatz 4 eingreift. The thin-walled outer ring 1 has a radial, non-cutting formed Board 2, which at its free end 3 is inclined to the bearing axis, has outwardly facing annular projection 4. The cage 5 is provided on the jacket of a side ring with an approximately V-shaped recess 6 into which the side rim 2 engages with its extension 4.
Der Käfig 5 wird durch die radiale Fläche 7 in der einen axialen Sichtung, durch die kegelige Fläche 8 in der anderen !Richtung axial geführt und gehalten. Der Zusammenbau erfolgt durch elastische Verformung des Käfigseitenringes bzw. des Außenringes.The cage 5 is through the radial surface 7 in the one axial sighting, guided axially through the conical surface 8 in the other! direction and held. It is assembled by elastic deformation of the Cage side ring or the outer ring.
