Description

Vorliegende Erfindung hat eine Verbesserung an Nadellagern nachdem Patent 857 300 zum Gegenstand. Dieses bezieht sich auf .ein Nadelläger, bei dem die Nadelrollen in einem Nadelikäfig geführt werden, der in einem aus Blechader Rohrbestehenden Laufring liegt und von diesem seitlich durch umgewalzte Flansche gehalten und geführt wind. Nadelkäfig und Laufring bilden: zusammen ein in sich geschlossenes Lagerelement. Der eine der beiden Seitenflansche des Laufringes wird bei der Fertigung des Laufringes, d. h. vor dem Zusammenbau des Lagers, umgewalzt, während der andere Flansch nach dem Einschieben des Nadelkäfigs umgelegt wird.Present invention is an improvement on needle bearings after Patent 857,300 to the object. This refers to .ein needle roller bearings, in which the needle rollers are guided in a needle cage, which is located in a ring made of sheet metal tube and is held and guided laterally by rolled flanges. Needle cage and raceway form: together a self-contained bearing element. One of the two side flanges of the raceway is rolled during manufacture of the raceway, ie before the assembly of the bearing, while the other flange is folded over after the needle cage has been pushed in.

Es hat sich nun gezeigt, daß der nachträglich umgewalzte Flansch .des äußeren Laufringes beim Betrieb des Lagers einem raschen Verschleiß unterworfen ist, weil dieser Flansch nicht :gehärtet werden darf, wie der übrige Teil .des Laufringes.It has now been shown that the subsequently rolled flange .des outer race subject to rapid wear during operation of the bearing is because this flange: may not be hardened, like the rest of the .the raceway.

Um diesen Mangel zu beheben, wird gemäß der Erfindung vorgeschlagen, zwischen der äußeren Stirnfläche des Nadelkäfigs und :dem nachträglich umgewalzten Flansch des Außenlaufringes einen gehärteten Ring einzufügen.In order to remedy this deficiency, it is proposed according to the invention, between the outer face of the needle cage and: the subsequently rolled over Insert a hardened ring flange of the outer race.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel der-Erfindung. Es ist Abb. r ein. Längsschnitt,durch das Lager und Abb. 2 ein Teilschnitt durch den Laufring.The drawing illustrates an embodiment of the invention. It is fig r a. Longitudinal section through the bearing and Fig. 2 a partial section the race.

Der Nadelkäfig q: zum Halten und Führen der Nadelrollen 3 besteht ebenso wie der Außenlaufring z aus einem Stahlmaterial, welches sich direkt oder im Einsatzverfahren härten läßt. Beim Härten des Außenlaüfringes r muß jedoch das nach dem Einbau des Nadelkäfigs umzuwalzende Ende 2 des Laufringes i weich gehalten werden, was durch besondere Maßnahmen beim HärtungsprozeB erreicht wird.The needle cage q: for holding and guiding the needle rollers 3 consists just like the outer race z made of a steel material, which is directly or can harden in the application process. However, this must be the case when hardening the outer ring r after the installation of the needle cage, the end 2 of the race i which is to be rolled over is kept soft which is achieved through special measures during the hardening process.

Die seitliche Führung des Nadelkäfigs q. erfolgt auf der einen Seite durch den bei der Fertigung des Laufringes r umgewalzten Flansch 211 und auf der anderen Seite durch einen gehärteten Ring 5, der an einer Schulter 6,des Laufringes i anliegt und durch das nach dem Einschieben des Nadelkäfigs q. umgewalzte Ende 2b -des Laufringes z gehalten wird.The lateral guidance of the needle cage q. takes place on the one hand by the flange 211 rolled over during the manufacture of the raceway r and on the the other side by a hardened ring 5 on a shoulder 6 of the race i is applied and after inserting the needle cage q. rolled end 2b - of the raceway z is held.

Ein besonderer Vorteil dieser Ausführung wird noch darin erblickt, daß das seitliche Führungsspiel des Nadelkäfigs sehr genau eingehalten werden kann.A particular advantage of this design is seen in that the lateral guide play of the needle cage can be adhered to very precisely.
