Description

Axial federnd ausgebildete Trennsicherung für lose ineinandergesetzte Laufringe eines Schrägkugellagers Die Erfindung bezieht sich auf eine axial federnd ausgebildete Trennsicherung für lose ineinandergesetzte Laufringe eines Schrägkugellagers, insbesondere eines Lenksäulenlagers.Axially resilient separating lock for loosely nested ones Races of an angular contact ball bearing The invention relates to an axially resilient designed separating protection for loosely nested races of an angular contact ball bearing, in particular a steering column bearing.

Bei einer bekannten Ausführung eines Schrägkugellagers erfolgt die Trennsicherung dadurch, daß auf den Innenlaufring eine Haltescheibe aufgeschraubt ist, die sich mit Kugeln gegen den Außenlaufring abstützt. Diese Ausführung ist nicht axial federnd.In a known embodiment of an angular contact ball bearing that takes place Separation protection in that a retaining washer is screwed onto the inner race which is supported by balls against the outer race. This execution is not axially resilient.

Bei einem bekannten, axial federnden Schrägkugellager, dessen Laufringe lose ineinander eingesetzt sind, erfolgt die Trennsicherung durch einen gewellten Stahldrahtring, der in einander entsprechende Ausdrehungen der Umlaufflächen der beiden Laufringe eingreift. Diese Anordnung ist schwierig zu montieren.In a known, axially resilient angular contact ball bearing, its races are loosely inserted into each other, the separation is secured by a corrugated Steel wire ring, the corresponding recesses of the circumferential surfaces of the engages both races. This arrangement is difficult to assemble.

Schließlich ist ein axial federnd ausgebildetes Wälzlager bekannt, bei welchem ein elastischer, auf der Welle sitzender Spannring an einem Ende einen radial über die eine Stirnfläche des Wälzlagerringes reichenden Bund aufweist und am anderen Ende einen Ringwulst besitzt, der die andere Stirnfläche des Wälzlagerringes mit einer das Aufziehen des Spannringes auf den Wälzlagerring gestattenden elastischen Verformbarkeit umgreift. Hierdurch wird zwar eine Axialsicherung erzielt, jedoch sind die Laufringe nicht lose ineinandergesetzt und durch den elastischen Spannring zusammengehalten.Finally, an axially resilient roller bearing is known, in which an elastic, on the shaft seated clamping ring at one end has radially over the one end face of the rolling bearing ring reaching collar and at the other end has an annular bead that forms the other end face of the rolling bearing ring with an elastic that allows the clamping ring to be pulled onto the roller bearing ring Deformability encompasses. An axial securing is achieved in this way, however the race rings are not loosely inserted into one another and by the elastic clamping ring held together.

Der Erfindung liegt die Aufgabe zugrunde, durch die axial federnd ausgebildete Trennsicherung die lose ineinandergesetzten Laufringe zuverlässig zusammenzuhalten und dabei die Montage des Lagers, d. h. das Zusammenfügen der Lagerteile, mit einem Griff zu ermöglichen.The invention is based on the object by the axially resilient trained separator to hold the loosely nested races together reliably and the assembly of the bearing, d. H. the joining of the bearing parts, with one Allow grip.

Die Lösung der Aufgabe besteht darin, daß eine kegelstumpfförmige, die beiden Laufringe gegen die Kugeln haltende elastische Ringscheibe zwischen dem Außenlaufring und radial nach außen gerichteten Nasen einer federnden Spannhülse eingeklemmt ist, die den Innenlaufring entlang seines Innenmantels und seiner den Nasen abgekehrten Seite eng umgreift und an ihrem freien Ende von radial federnden Lappen gebildet ist, an denen in axialem Abstand von den Laufringen die Nasen angeordnet sind.The solution to the problem is that a frustoconical, the two races against the balls holding elastic washer between the Outer race and radially outwardly directed lugs of a resilient clamping sleeve is clamped, which the inner race along its inner jacket and its the Lugs facing away from the side tightly embraced and radially resilient at their free end Flap is formed on which the lugs are arranged at an axial distance from the races are.

Die Figur erläutert die Erfindung an einem Ausführungsbeispiel.The figure explains the invention using an exemplary embodiment.

Eine federnde Spannhülse 1, die vorzugsweise aus Kunststoff besteht, umfaßt den Innenlaufring 2 des Kugelkranzes 3 und besitzt an ihrem freien Ende federnde Lappen 4 mit außenseitigen Nasen 5. Eine elastische, leicht konische Ringscheibe 6 stützt sich einerseits gegen den Außenlaufring 7 des Lagers, andererseits gegen die Nasen 5 der Lappen 4 ab. Die elastische Ringscheibe kann beispielsweise aus Kunststoff, Stahl oder NE-Metallen bestehen. Der Innenlaufring 2 und der Außenlaufring 7 sind üblicherweise aus Stahlblech gefertigt und bei Bedarf gehärtet.A resilient clamping sleeve 1, which is preferably made of plastic, comprises the inner race 2 of the ball ring 3 and has resilient at its free end Tabs 4 with outside lugs 5. An elastic, slightly conical washer 6 is supported on the one hand against the outer race 7 of the bearing, on the other hand against the lugs 5 of the tabs 4 off. The elastic ring disk can for example be made of Plastic, steel or non-ferrous metals are made. The inner race 2 and the outer race 7 are usually made of sheet steel and hardened if necessary.

Bei der Montage des Lagers wird die elastische Ringscheibe 6 über die federnden Lappen 4 der Spannhülse gedrückt, wobei diese Lappen nach innen ausweichen. Nach dem Einsetzen der elastischen Ringscheibe federn die Lappen 4 wieder in ihre Ausgangsstellung zurück, wobei die Nasen 5 die Ringscheibe 6 hintergreifen.When assembling the bearing, the elastic washer 6 is over pressed the resilient tabs 4 of the clamping sleeve, these tabs yielding inward. After inserting the elastic washer, the tabs 4 spring back into their Starting position back, the lugs 5 engaging behind the annular disk 6.

Die Ringscheibe 6 ist so bemessen, daß das Lager kraftschlüssig angestellt wird, dadurch, daß die Scheibe einerseits an den Nasen 5 der Spannhülse 1 und andererseits am Außenring 7 des Lagers federnd anliegt. Unter Belastung werden dann die in axialer Richtung auftretenden Kräfte federnd aufgenommen.The ring washer 6 is dimensioned so that the bearing is non-positively employed is, in that the disc on the one hand on the lugs 5 of the clamping sleeve 1 and on the other hand resiliently rests on the outer ring 7 of the bearing. Under load, the in axial Direction occurring forces resiliently absorbed.

Durch die Erfindung ist ein selbsthaltendes Lager geschaffen, welches z. B. einer Lenksäule während des Fahrbetriebs eine gewisse axiale Beweglichkeit verleiht.The invention provides a self-retaining bearing which z. B. a steering column while driving a certain axial mobility confers.
