Gebiet der ErfindungField of the invention
Die Erfindung betrifft eine Wälzlageranordnung mit einer kreisringförmigen Nadelhülse, deren innere Oberfläche eine Laufbahn für Wälzkörper bildet, welche als Lagernadeln ausgeführt und in Umfangshchtung in Abständen hintereinander in einem Käfig angeordnet sind, der in die Nadelhülse eingesetzt ist und eine Welle umgibt, an deren Mantelfläche die Lagernadeln abrollbar abgestützt sind, wobei die Nadelhülse in einen Aufnahmeraum, z. B. eine Bohrung eines Gehäuses passend eingesteckt ist.The invention relates to a rolling bearing assembly with an annular needle sleeve, whose inner surface forms a raceway for rolling elements, which are designed as bearing needles and arranged in the circumferential direction at intervals in a row in a cage which is inserted into the needle sleeve and surrounds a shaft on the lateral surface of which Storage needles are supported rollable, wherein the needle sleeve in a receiving space, for. B. a hole of a housing is inserted appropriately.
Hintergrund der ErfindungBackground of the invention
Für die Sicherung gegen Axialverschiebungen einer Nadelhülse in einem Auf- nahmeraum eines Gehäuses werden häufig besondere Sicherungsringe verwendet, womit in nachteiliger Weise ein zusätzlicher Montageaufwand verbunden ist. Das Anbringen eines Sicherungsringes ist oft nur schwer möglich, da ein Werkzeugzugang nicht immer in ausreichendem Maße gegeben ist. Oft fehlt auch der für Sicherungsringe erforderliche axiale Bauraum, so dass deren Anbringung gar nicht möglich ist.For securing against axial displacements of a needle sleeve in a receiving space of a housing often special retaining rings are used, which is disadvantageously connected to an additional installation effort. The attachment of a retaining ring is often difficult, since a tool access is not always given sufficient. Often also missing for circlips required axial space, so that their attachment is not possible.
Aus der Druckschrift DE 197 81 320 B4 ist eine Wälzlageranordnung der eingangs genannten Art bekannt, bei welcher eine als erstes Ringteil bezeichnete Nadelhülse mit Lagernadeln von einem zweiten Ringteil umgeben ist, welches sich in der Aufnahmebohrung eines Gehäuses befindet. Über mögliche Siche- rungsmaßnahmen gegen axiales Herausbewegen der Ringteile aus der Gehäusebohrung ist in dieser Veröffentlichung nichts erwähnt.
Die Druckschrift US 2,779,641 zeigt und beschreibt ein als Kugellager ausgebildetes Wälzlager mit einem massiven Lageraußenring. Dieser ist in eine Öffnung bzw. Ausnehmung einer Wand eingesteckt. Er ist vorzugsweise aus wärmebehandeltem Stahl hergestellt und an einer Umfangsstelle mit einem radial durchgehenden Schlitz versehen. Dadurch kann er elastisch zusammengedrückt werden und sich zurückfedernd wieder aufweiten. An der Mantelfläche des Außenringes ist eine Vielzahl von Auszackungen oder Rippen angeordnet. Die Ausdehnungskraft des Außenringes bewirkt, dass die Auszackungen nach außen gegen die innere Oberfläche der Wandöffnung bzw. -ausnehmung ge- drückt werden, in der sich der Außenring befindet. Dadurch werden die Auszackungen in das Material der Wand eingegraben. Auf diese Weise wird der Außenring in der Wand axial gehalten.From the document DE 197 81 320 B4 a rolling bearing assembly of the type mentioned is known in which a designated as the first ring member needle sleeve is surrounded with bearing needles of a second ring member, which is located in the receiving bore of a housing. About possible insurance measures against axial moving out of the ring parts of the housing bore is not mentioned in this publication. The document US 2,779,641 shows and describes a designed as a ball bearing roller bearing with a massive bearing outer ring. This is inserted into an opening or recess of a wall. It is preferably made of heat-treated steel and provided at a peripheral location with a radially continuous slot. As a result, it can be compressed elastically and widen back springing back. On the lateral surface of the outer ring a plurality of serrations or ribs is arranged. The expansive force of the outer ring causes the serrations to be pressed outwardly against the inner surface of the wall opening or recess in which the outer ring is located. This buries the serrations in the material of the wall. In this way, the outer ring is held axially in the wall.
Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine Lageranordnung zu schaffen, bei welcher die in einen Aufnahmeraum eines Gehäuses eingesteckte Nadelhülse in einfacher Weise gegen ein axiales Herauslösen aus dem Gehäuse gesichert ist.The invention has for its object to provide a bearing assembly in which the inserted into a receiving space of a housing needle sleeve is secured in a simple manner against axial detachment from the housing.
Zusammenfassung der ErfindungSummary of the invention
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass an der Nadelhülse an wenigstens einer Umfangsstelle ihrer äußeren Oberfläche ein radial abste- hender Widerhaken angeordnet ist, welcher nach dem Einstecken der Nadelhülse in das Gehäuse in eine zu dem Aufnahmeraum offene Gehäuseausneh- mung infolge elastischer Hülsenverformung eingeschnappt ist. Besonders kostengünstig ist es dabei, wenn die Nadelhülse nur mit einem einzelnen Widerhaken ausgebildet und die offene Gehäuseausnehmung in Form einer umlau- fenden Nut im Aufnahmeraum der Nadelhülse gebildet wird. Alternativ ist es jedoch auch möglich, anstelle einer umlaufenden Nut mehrere, der Anzahl der Widerhaken entsprechende Nutabschnitte oder auch Sackbohrungen als Ge-
häuseausnehmungen auszubilden, die zudem den Vorteil haben, dass die Nadelhülse somit zusätzlich gegen Verdrehen in Umfangsrichtung gesichert ist.This object is achieved according to the invention in that a radially projecting barb is arranged on the needle sleeve at at least one peripheral point of its outer surface, which is snapped into a housing recess open to the receiving space as a result of elastic sleeve deformation after insertion of the needle sleeve into the housing , It is particularly cost effective if the needle sleeve is formed only with a single barb and the open housing recess is formed in the form of a circumferential groove in the receiving space of the needle sleeve. Alternatively, however, it is also possible, instead of a circumferential groove, to have a plurality of groove sections corresponding to the number of barbs or also blind bores as a form housing recesses, which also have the advantage that the needle sleeve is thus additionally secured against rotation in the circumferential direction.
Die Nadelhülse kann ein spanlos hergestelltes Bauteil sein, beispielsweise ein Blechteil aus Stahl. Sie kann mit dem Widerhaken als einstückiges Bauteil in einem Ziehverfahren hergestellt sein, durch welches der Widerhaken an der Nadelhülse angeformt ist.The needle sleeve may be a chipless produced component, for example, a sheet metal part made of steel. It can be made with the barb as a one-piece component in a drawing process, by which the barb is formed on the needle sleeve.
Die Schnappfunktion bewirkt als axiale Sicherung der Nadelhülse eine Kosten- reduzierung und eine Vereinfachung des Montagevorganges. Ein zusätzlicher Sicherungsring ist in diesem Falle nicht mehr erforderlich.The snap-action function as axial securing of the needle sleeve reduces costs and simplifies the assembly process. An additional locking ring is no longer necessary in this case.

häuses 5 passend eingesteckt. Der Aufnahmeraum 4 ist in dem Gehäuse 5 in der Form einer Bohrung angeordnet.Rolling elements. The needle sleeve 1 is axially in a receiving space 4 of a Ge housing 5 fitting inserted. The receiving space 4 is arranged in the housing 5 in the form of a bore.
In dem Aufnahmeraum 4 des Gehäuses 5 ist mittels der Nadelhülse 1 eine Welle 6 drehbar gelagert. Diese wird koaxial von der Nadelhülse 1 umgeben, wobei die Lagernadeln 3 sowohl an der Mantelfläche 7 der Welle 6 als auch an der inneren Oberfläche der Nadelhülse 1 , die als Laufbahn 8 wirkt, abrollbar abgestützt sind.In the receiving space 4 of the housing 5, a shaft 6 is rotatably supported by means of the needle sleeve 1. This is coaxially surrounded by the needle sleeve 1, wherein the bearing needles 3 are supported both on the lateral surface 7 of the shaft 6 and on the inner surface of the needle sleeve 1, which acts as a raceway 8, unrolling.
Erfindungsgemäß ist an der Nadelhülse 1 an einer Umfangsstelle ein radial abstehender Widerhaken 9 ausgebildet. Dieser ist während der Herstellung der Nadelhülse 1 durch ein Ziehverfahren an der Nadelhülse 1 angeformt, so dass die Nadelhülse 1 mit dem Widerhaken 9 ein einstückiges Bauteil bildet.According to the invention, a radially projecting barb 9 is formed on the needle sleeve 1 at a peripheral location. This is formed during the manufacture of the needle sleeve 1 by a pulling method on the needle sleeve 1, so that the needle sleeve 1 forms a one-piece component with the barb 9.
Entsprechend der Form und der Lage des Widerhakens 9 an der Nadelhülse 1 ist in dem Gehäuse 5 eine als umlaufende Nut ausgebildete Gehäuseausneh- mung 10 angeordnet, die von dem Aufnahmeraum 4 ausgeht. Auf diese Weise kann beim axialen Einstecken der Nadelhülse 1 in den Aufnahmeraum 4 der Widerhaken 9 in die Gehäuseausnehmung 10 einschnappen (einrasten), wobei im Bereich des Widerhakens 9 eine elastische Verformung der Nadelhülse 1 erfolgt. Dadurch ist die Nadelhülse 1 gegen ein axiales Herausbewegen aus dem Ausnahmeraum 4 des Gehäuses 5 gesichert.Corresponding to the shape and the position of the barb 9 on the needle sleeve 1, a housing recess 10 designed as a circumferential groove is arranged in the housing 5, which extends from the receiving space 4. In this way, when the needle sleeve 1 is inserted axially into the receiving space 4, the barbs 9 snap into the housing recess 10, whereby in the region of the barb 9 an elastic deformation of the needle sleeve 1 takes place. As a result, the needle sleeve 1 is secured against axial movement out of the exception space 4 of the housing 5.
In Figur 1 befindet sich der Widerhaken 9 im Bereich der linksseitigen Stirnflä- che der Nadelhülse 1. Im Bereich von deren rechtsseitiger Stirnfläche befindet sich im Aufnahmeraum 4 ein Ringbord 11 des Gehäuses 5, der ebenfalls eine Axialverschiebung der Nadelhülse 1 begrenzt.
BezugszahlenlisteIn FIG. 1, the barb 9 is located in the region of the left-hand end face of the needle sleeve 1. In the region of its right-hand end face, a ring flange 11 of the housing 5 is located in the receiving space 4, which likewise limits an axial displacement of the needle sleeve 1.
