Anwendungsgebiet der Erfindungfield of use the invention
Die Erfindung betrifft ein gegen axiales Verschieben gesichertes, spanlos geformtes dünnwandiges rotationssymmetrisches Bauteil, das von einer Aufnahmebohrung eines Gehäuses aufgenommen ist. Derartige Bauteile sind beispielsweise Innen- oder Außenringe von Wälzlagern, Gleitlagern oder Freiläufen.The The invention relates to a secured against axial displacement, non-cutting shaped thin-walled rotationally symmetrical component, of a receiving bore of a housing is included. Such components are, for example, indoor or outer rings of rolling bearings, Plain bearings or freewheels.
Hintergrund der Erfindungbackground the invention
Derartige als Hülsenlager ausgebildete Bauteile, die spanlos hergestellte gehärtete, aber nicht geschliffene Außenringe aufweisen, sind bereits seit langem vorbekannt. Ein solch gattungsgemäßes Lager ist beispielsweise in dem Fachbuch Albert/Köttrich „Wälzlager", Springer-Verlag Wien, New York, 1987, auf Seite 29, beschrieben. Derart gattungsgemäß ausgebildete Hülsenlager müssen nun durch aufwändige Maßnahmen in einer Aufnahmebohrung eines Gehäuses fixiert werden.such as a sleeve bearing trained components, the non-machined hardened, but non-ground outer rings have already been known for a long time. Such a generic camp is for example in the reference book Albert / Köttrich "Wälzlager", Springer-Verlag Vienna, New York, 1987, on page 29. Such generic trained sleeve bearing have to now through elaborate activities be fixed in a receiving bore of a housing.
Da, wie der Fachmann weiß, solche Hülsenlager erst durch Festsitz in der Gehäusebohrung ihre endgültige runde Form erhalten, werden sie in der Regel mit Überdeckung in die Gehäusebohrung eingepresst. Hierbei besteht die Gefahr, dass bei zu geringer Überdeckung der erforderliche Festsitz nicht erreicht wird, d. h., die Hülsenlager wandern in axialer Richtung aus der Gehäusebohrung heraus. Ist im Gegensatz die Überdeckung zu groß gewählt, besteht die Gefahr, dass das Hülsenlager beim Einpressen in die Aufnahmebohrung deren Form verändert, so dass die erforderliche Rundheit nicht gegeben ist. Dies trifft insbesondere dann zu, wenn das Hülsenlager in eine weiche Umgebungskonstruktion, beispielsweise in ein Gehäuse aus Aluminium, eingesetzt wird.There, as the expert knows, such sleeve bearings only by tight fit in the housing bore their final Obtained round shape, they are usually covered into the housing bore pressed. There is a risk here that too little coverage the required interference fit is not achieved, d. h., the sleeve bearings migrate out of the housing bore in the axial direction. Is in contrast the overlap too big, exists the danger of the sleeve bearing when pressed into the receiving hole changes their shape, so that the required roundness is not given. This is especially true then too, if the sleeve bearing in a soft environment construction, for example in a housing Aluminum, is used.
Um ein Herauswandern des äußeren Lagerringes aus der Gehäusebohrung zu verhindern, ist es ebenfalls bekannt, den äußeren Lagerring mit einer umlaufenden Rändelung zu versehen. Dies hat den Nachteil, dass zur Erstellung der Rändelung ein zusätzlicher aufwändiger Arbeitsgang erforderlich ist und dass durch die Rändelung eine ungleichmäßige Wanddicke, und damit ein nicht definierter Hüllkreis realisiert ist, der sich wiederum auf die zu erzielende Rundheit negativ auswirkt.Around a migration of the outer bearing ring from the housing bore To prevent, it is also known, the outer bearing ring with a circumferential knurling to provide. This has the disadvantage that to create the knurling an additional one complex Operation is required and that by knurling an uneven wall thickness, and thus an undefined enveloping circle is realized, the in turn has a negative effect on the roundness to be achieved.

Zusammenfassung der ErfindungSummary the invention
Ausgehend von den Nachteilen des bekanntes Standes der Technik liegt daher der Erfindung die Aufgabe zu Grunde, für gattungsgemäß ausgebildete Bauteile eine axiale Verschiebesicherung zu entwickeln, die einerseits sehr wirkungsvoll und andererseits auch kostengünstig herstellbar ist.outgoing from the disadvantages of the known prior art is therefore The invention is based on the task for generically designed components to develop an axial displacement safety, on the one hand very effective and on the other hand also inexpensive to produce.
Erfindungsgemäß wird diese Aufgabe nach dem kennzeichnenden Teil von Anspruch 1 in Verbindung mit dessen Oberbegriff dadurch gelöst, dass wenigstens an einer Umfangsstelle des Bauteils eine radial hervorstehende Haltenase derart angeformt ist, dass ein nicht unterbrochener Materialzusammenhang zwischen der Haltenase und dem Bauteil realisiert ist, wobei die Haltenase in eine zugehörige Ausnehmung im Gehäuse elastisch einschnappbar ist.According to the invention this Task according to the characterizing part of claim 1 in conjunction solved with the preamble by at least one Peripheral point of the component a radially projecting retaining lug is formed such that an uninterrupted material connection between the retaining lug and the component is realized, wherein the Retaining lug in an associated recess in the case is elastically snap-in.
Ein Vorteil der erfindungsgemäß ausgebildeten Haltenasen besteht darin, dass sich diese durch einen zusätzlichen Prägevorgang am äußeren Lagerring in einfacher Weise anbringen lassen. Durch den nicht unterbrochenen Materialzusammenhang zwischen äußerem Lagerring und Haltenasen ist sichergestellt, dass deren Bruch, insbesondere bei hoher Axialbelastung, ausgeschlossen ist. Es ist auch von Vorteil, dass Haltenasen und Aufnahmebohrung in ihren Größenverhältnissen so abgestimmt sind, dass diese beim Einpressen in die Aufnahmebohrung sich im elastischen Bereich verformen, das bedeutet, dass die Haltenasen nach dem Erreichen der in der Anschlusskonstruktion eingebrachten Ausnehmung wieder auffedern.One Advantage of the invention designed Retaining lugs is that they are replaced by an additional embossing process on the outer bearing ring attach in a simple manner. By the uninterrupted Material connection between outer bearing ring and retaining lugs ensures that their breakage, in particular at high axial load, is excluded. It's also an advantage that retaining lugs and receiving bore are matched in their size ratios so that this when pressed into the mounting hole in the elastic Deform area, which means that the retaining lugs after reaching the recess introduced in the adjacent construction again spring open.
Weitere vorteilhafte Ausführungsvarianten der Erfindung sind in den Unteransprüchen beschrieben.Further advantageous embodiments of the Invention are in the subclaims described.
So ist nach Anspruch 2 vorgesehen, dass die Haltenase in Montagerichtung einen abfallenden Verlauf aufweist. Dadurch ist sichergestellt, dass beim Einschieben des Hülsenlagers in die Aufnahmebohrung das elastische Einfedern der Haltenasen allmählich erfolgen kann.So is provided according to claim 2, that the retaining lug in the mounting direction has a sloping course. This ensures that when inserting the sleeve bearing in the receiving bore, the elastic compression of the retaining lugs take place gradually can.
Nach einem weiteren Merkmal der Erfindung gemäß Anspruch 3 ist vorgesehen, dass neben der Haltenase beidseitig in Umfangsrichtung durchgehende Freistanzungen angeordnet sind. Diese Freistanzungen sind insbesondere dann erforderlich, wenn relativ dickes Bandmaterial zur Herstellung des Bauteils verwendet wird. Die Freistanzungen sorgen dafür, dass die erforderliche Elastizität der Haltenasen durch die Veränderung der Federkennlinie des Bauteils gewährleistet ist.According to a further feature of the invention according to claim 3 it is provided that in addition to the retaining lug on both sides in the circumferential direction continuous free distances are arranged. These free cuts are particularly necessary when relatively thick strip material is used to make the component. The free-punches ensure that the required elasticity of the retaining lugs is ensured by the change in the spring characteristic of the component.
Schließlich ist nach den Ansprüchen 4 und 5 vorgesehen, dass entweder die Haltenase außerhalb des Laufbahnbereichs der Lagernadeln angeordnet ist oder dass die Haltenase im Laufbahnbereich, aber außerhalb der Lastzone angeordnet ist, wobei das Bauteil ein äußerer Lagerring eines Hülsenlagers ist, auf dessen Laufbahn Lagernadeln abwälzen.Finally is according to the claims 4 and 5 provided that either the retaining lug outside the Track area of the bearing needles is arranged or that the retaining lug in the career area, but outside the load zone is arranged, wherein the component is an outer bearing ring a sleeve bearing is on whose career rolling stock needles.
Durch beide Maßnahmen wird der Laufbahnbereich der Wälzkörper nicht beeinträchtigt, so dass ein besonders ausgeglichener und ruhiger Lauf der Lageranordnung gewährleistet ist.By both measures the raceway area of the rolling elements is not impaired so that a particularly balanced and smooth running of the bearing assembly guaranteed is.
Die Erfindung wird an nachstehenden Ausführungsbeispielen näher erläutert.The Invention will be explained in more detail in the following embodiments.
