Description
Die Erfindung betrifft eine Anordnung zur Sicherung eines Sprengringes nach dem Oberbegriff des Patentanspruches 1 und 6.The The invention relates to an arrangement for securing a snap ring according to the preamble of claim 1 and 6.
Sprengringe, die in eine Ringnut einer Welle oder einer Bohrung eingesetzt werden und der axialen Abstützung von auf der Welle oder in der Bohrung angeordneten Bauteilen dienen, neigen im Betrieb, insbesondere bei höheren Drehzahlen und durch Axial- und Radialbewegungen der umgebenden Bauteile ausgelöste Schwingungen dazu, sich aus ihrer Verankerung in der Ringnut zu lösen – insbesondere treten Sprengringe auf Wellen infolge Durchmesservergrößerung aus der Ringnut aus. Man hat daher vorgeschlagen, eine radiale Auswärtsbewegung der Stoßenden eines Sprengringes durch Anordnung von Sicherungselementen zu blockieren.Snap rings, which are inserted into an annular groove of a shaft or a bore and the axial support serve components arranged on the shaft or in the bore, tend in operation, especially at higher speeds and by axial and radial movements of the surrounding components triggered vibrations to break away from their anchorage in the annular groove - especially kicking Circlips on waves due to increase in diameter from the annular groove. It has therefore been proposed, a radial outward movement of the butt ends of a Snap ring to block by arranging fuse elements.
In der DE-PS 25 08 677 ist eine Sprengringsicherung für einen Wellensprengring offenbart, bei welcher ein zweiter Sprengring radial außerhalb des Wellensprengringes in einer Bohrung angeordnet ist. Diese Maßnahme erfordert einen zusätzlichen Sprengring und entsprechenden radialen Bauraum, der insbesondere bei Getrieben nicht immer zur Verfügung steht.In DE-PS 25 08 677 is a snap ring for a Shaft snap ring disclosed in which a second snap ring radially outside the Wellenensprengringes is arranged in a bore. This action requires an additional snap ring and corresponding radial space, especially in transmissions not always available stands.
In der älteren Patentanmeldung der Anmelderin mit dem Aktenzeichen 103 02 075.6 ist eine Sprengringsicherung, insbesondere für Teile eines Getriebes beschrieben, bei welcher die Stoßenden eines Sprengringes an ihrer radialen Aus- oder Einwärtsbewegung durch Anordnung vom Rampen gehindert sind. Eine Bewegung des Sprengringes in Umfangs richtung ist durch einen Noppen zwischen den Stoßenden blockiert. Diese Sicherung erfordert ein Einfädeln des Sprengringes bei der Montage, was zusätzliche Montagezeit erfordert.In the older one Patent application of the applicant with the file number 103 02 075.6 is a snap ring, especially for parts of a transmission described where the butt ends of a Retaining ring at its radial outward or inward movement by arrangement are prevented from ramping. A movement of the snap ring in the circumferential direction is blocked by a pimple between the butt ends. This fuse requires threading the snap ring during assembly, which requires additional installation time.
Es ist Aufgabe der vorliegenden Erfindung, eine Anordnung zur Sicherung eines Sprengringes der eingangs genannten Art zu schaffen, die zu niedrigen Kosten herstellbar sowie leicht und schnell montierbar ist.It Object of the present invention, an arrangement for securing a snap ring of the type mentioned above to create Low cost to produce and easy and quick to install is.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Erfindungsgemäß ist vorgesehen, dass im Bereich des Umfangsspaltes am zweiten Bauteil ein Sperrelement vorgesehen ist, welches vorzugsweise einstückig mit dem Bauteil ausgebildet ist. Damit wird der Vorteil erreicht, dass der Sprengring in Umfangsrichtung festgelegt und damit gesichert ist. Vorteilhaft ist ferner, dass kein zusätzliches Teil für die Sicherung des Sprengringes benötigt wird.These The object is solved by the features of claim 1. According to the invention, it is provided that in the region of the circumferential gap on the second component, a blocking element is provided, which is preferably formed integrally with the component is. Thus, the advantage is achieved that the snap ring in the circumferential direction fixed and thus secured. It is also advantageous that no additional Part for the securing of the snap ring is needed.
In vorteilhafter Ausgestaltung der Erfindung sind die Stoßenden abgeschrägt und laufen in ihrem äußeren Durchmesser spitz zu (so genannter V-Stoß). Durch diese Abschrägung ergibt sich der Vorteil, dass die Stoßenden beim Auftreffen auf das Sperrelement radial nach außen, d. h. in die Ringnut gedrückt werden – sie sind damit an einer radialen Einwärtsbewegung gehindert. Daraus ergibt sich der Vorteil, dass der Sprengring gegen Austreten aus der Ringnut gesichert ist.In Advantageous embodiment of the invention, the butt ends are chamfered and run in their outer diameter pointed (so-called V-shock). By this bevel There is the advantage that the butt ends when hitting the blocking element radially outward, d. H. pressed into the annular groove will you are thus prevented from radial inward movement. from that There is the advantage that the snap ring against leakage the annular groove is secured.
In weiterer vorteilhafter Ausgestaltung der Erfindung ist das Sperrelement keilförmig ausgebildet und weist zu den Stirnflächen der Stoßenden parallel laufende Keilflä chen auf. Damit wird der Vorteil erreicht, dass die schrägen Stoßenden direkt auf den Keilflächen aufgleiten und nach radial außen, d. h. in die Ringnut gedrückt werden. Der Sprengring ist somit in tangentialer und radialer Richtung gesichert.In Another advantageous embodiment of the invention is the blocking element cuneiform formed and has parallel to the end faces of the butt ends running wedge surfaces on. Thus, the advantage is achieved that the oblique butt ends directly on the wedge surfaces slip on and radially outward, d. H. pressed into the annular groove become. The snap ring is thus in the tangential and radial directions secured.
Die Erfindung wird auch durch die Merkmale des Patentanspruches 6 gelöst, d. h. für eine formschlüssige Verbindung zwischen einem Hohlrad und einem Hohlradträger, welcher über einen Sprengring gegenüber dem Hohlrad axial festgelegt ist. Zwischen Hohlrad und Hohlradträger besteht ein durch ein Mitnahmeprofil am Hohlrad und ein Zahnprofil am Hohlradträger hergestellter Formschluss. Die Ringnut, in welcher der Sprengring angeordnet ist, ist in das Mitnahmeprofil, welches aus einzelnen Klauen besteht, eingeschnitten. Derartige Bauteile werden insbesondere bei Kraftfahrzeuggetrieben verwendet. Erfindungsgemäß ist vorgesehen, dass die Stoßenden abgeschrägt sind und dass zwischen den Stoßenden ein Sperrelement, insbesondere ein nach außen spitz zulaufender Keil angeordnet ist. Der Sprengring wird somit einerseits in Umfangsrichtung an einer Bewegung gehindert und andererseits durch Aufgleiten auf die Keilflächen in seine Ringnut gezwungen. Vorteilhafterweise ist das Sperrelement bzw. der Keil einstückig mit dem Hohlradträger ausgebildet, was insbesondere durch eine Prägung bzw. eine so genannte Eindrückung oder Blechdurchstellung des keilförmigen Sperrelementes erreicht wird. Damit fallen praktisch keine zusätzlichen Herstellkosten an, und es ist auch keine Montage von zusätzlichen Sicherungselementen nach der Montage des Sprengringes erforderlich. Somit ergibt sich eine Sprengringsicherung, die zu minimalen Kosten herstellbar ist und keine zusätzlichen Bauteile sowie zusätzliche Montagearbeiten erfordert.The Invention is also solved by the features of claim 6, d. H. for one positive Connection between a ring gear and a Hohlradträger, which via a Circlip opposite axially fixed to the ring gear. Between ring gear and Hohlradträger consists one produced by a driving profile on the ring gear and a tooth profile on Hohlradträger Form-fitting. The annular groove in which the snap ring is arranged, is in the transport profile, which consists of individual claws, cut. Such components are particularly in motor vehicle transmissions used. According to the invention, it is provided that the butt ends bevelled are and that between the butt ends a blocking element, in particular an outwardly tapered wedge is arranged. The snap ring is thus on the one hand in the circumferential direction prevented from moving and, on the other hand, by sliding up the wedge surfaces forced into its groove. Advantageously, the blocking element or the wedge in one piece with the ring gear carrier formed, which in particular by an embossing or a so-called depression or Blechdurchstellung the wedge-shaped locking element achieved becomes. This incurs practically no additional manufacturing costs, and it is also no assembly of additional security elements required after mounting the snap ring. Thus results a snap ring fuse that can be produced at minimal cost and No additional Components as well as additional installation work requires.
