Bei einer Vorrichtung der eingangsgenannten Art wird durch die im kennzeichnenden Teil des Hauptanspruches angegebenen Merkmale die Sicherstellung der ordnungsge¬ mäßen Ausrichtung des Sicherungsdrahtrings relativ zu den zusammenzuhaltenden Bauteilen sowie der Schutz der Drahtanordnung vor unbefugtem Zugriff erreicht.In the case of a device of the type mentioned at the outset, the features specified in the characterizing part of the main claim ensure that the securing wire ring is properly aligned relative to the components to be held together and that the wire arrangement is protected against unauthorized access.
Durch bündiges Eindrücken der Sicherungshülse in die Werkstücksbohrung wird der an der abgewinkelten Stirn¬ seite der Sicherungshülse anliegende Sicherungsdrah¬ tring zwischen der Innenwand der Werkstücksbohrung und der axial abgeflachten Außenseite, des zur Bohrungsachse rotationssymmetrisehen Elements zwangsnotwendig nach außen in die, die Innenwand des zylindrischen Werk¬ stücks umlaufende Ringnut gedrückt und rastet dort si¬ cher und vollständig in diese ein. Der ordnungsgemäße Sitz des Sicherungsdrahtringes in der Ringnut ist da¬ durch sichergestellt. Die Sicherungshülse bildet dar- überhinaus einen Schutz gegen unbefugte Manipulierungen, da ein Zugriff auf den in der.Ringnut einliegenden Sicherungsdrahtring nicht mehr möglich ist.By pushing the locking sleeve flush into the workpiece bore, the locking wire ring lying on the angled face of the locking sleeve between the inner wall of the workpiece bore and the axially flattened outside, of the element rotationally symmetrical to the bore axis, is inevitably necessary to the outside, into the inner wall of the cylindrical workpiece Circumferential annular groove pressed and snaps securely and completely into this. This ensures that the securing wire ring is properly seated in the annular groove. The locking sleeve also provides protection against unauthorized manipulation, since it is no longer possible to access the locking wire ring in the ring groove.
Der Korrosionschutz des Sicherungsdrahtringes wird durch eine entsprechende Auswahl des Werkstoffes gewährleistet.Corrosion protection of the locking wire ring is guaranteed by an appropriate selection of the material.
Da die Sicherungshülse vorzugsweise aus Blech geformt ist, wird deren Festsitz über eine Presspassung erreichbar. Durch die Wahl des Hulsenmaterials ist ein zusätzlicher Korrosionsschutz für den Drahtring durch eine Fernwirkung bewirkt.Since the securing sleeve is preferably formed from sheet metal, its tight fit can be achieved via an interference fit. The choice of the sleeve material provides additional corrosion protection for the wire ring through a long-distance effect.
Die vorgeschlagene Sicherungshülse gewährleistet daher eine einwandfreie Montage sowie Manipulierschutz bei kostengünstiger Herstellbarkeit und leichter Montierbarkeit.The proposed locking sleeve therefore ensures proper installation and protection against tampering inexpensive to manufacture and easy to assemble.

Aus Figuren 1a und 1b ist der durch eine ringförmige Drahtanordnung gebildete Sicherungsdrahtring 1 ersichtlich. Dabei ist der Sicherungsdrahtring 1 in Fi¬ gur 1 a in einem Durchgangsstadium der Montage dargestellt, während er in der durch Figur 1b darge¬ 0 stellten Position in seiner endgültigen Lage aufgezeigt ist. Die endgültige Lage des Sicherungsdrahtringes 1 wird bei der Montage dadurch erreicht, daß dieser an der dem zur Bohrungsachse rotationssymmetrischen Ele-The securing wire ring 1 formed by an annular wire arrangement can be seen from FIGS. 1a and 1b. The securing wire ring 1 is shown in FIG. 1 a in a through stage of assembly, while it is shown in its final position in the position shown by FIG. 1 b. The final position of the locking wire ring 1 is achieved during assembly by the fact that it is on the element that is rotationally symmetrical to the axis of the bore.
„,- ment 2 zugewandten Stirnseite 3 der Sicherungshülse 4 - auf die Zeichnung bezogen - nach oben geführt wird und dann zwangsnotwendig in die aus einer Ringnut 5 beste¬ hende Sicherungsrille in der Innenwandung des zylindri¬ schen Werkstückes 6 einrastet. Der Sicherungsdrahtring 0 1 ist daher in montiertem Endzustand durch die Siche¬ rungshülse 4 verdeckt, wodurch ein Korrosions- und Ma- nipulierungsschutz gewährleistet ist, da eine Einwir¬ kung von außen auf den Sicherungsdrahtring 1 in dieser Lage nicht mehr möglich ist. Die an ihrer Stirnseite 3", - 2 facing end face 3 of the securing sleeve 4 - based on the drawing - is guided upwards and then necessarily engages in the securing groove consisting of an annular groove 5 in the inner wall of the cylindrical workpiece 6. The securing wire ring 0 1 is therefore covered in the assembled final state by the securing sleeve 4, which ensures protection against corrosion and manipulation, since it is no longer possible to act on the securing wire ring 1 in this position from the outside. The 3
35 kegelförmig zulaufende Sicherungshülse 4 stellt dabei aufgrund ihrer aus Blech gebildeten Ausformung sicher, daß im Montageendstadium der Festsitz des Sicherungs- - k - drahtringes 1 in der Ringnut 5 über eine Presspassung erreicht wird. Die Lage der Sicherungshülse 4 im End¬ stadium der Montage ist durch Figur 1b dargestellt. Während des Montagevorganges wird die Sicherungshülse 4 bündig mit der Innenwandung der Werkstücksbohrung in das Werkstück 6 gegen das zur Bohrungsachse rotations¬ symmetrische Element 2 eingedrückt. Das zur Bohrungs¬ achse rotationssymmetrische Element 2 kann dabei durch eine Welle oder ein Deckelelement gebildet werden. Da¬ durch wird die endgültige Lage des Sicherungsdrahtrin¬ ges 1 in der aus Figur 1b ersichtlichen Position bei Abschluß des Montagevorganges erreicht. 35 tapered locking sleeve 4 ensures due to their shape formed from sheet metal that the tight fit of the fuse in the final assembly stage - k - wire rings 1 in the ring groove 5 is achieved by a press fit. The position of the securing sleeve 4 in the final stage of assembly is shown by FIG. 1b. During the assembly process, the securing sleeve 4 is pressed flush with the inner wall of the workpiece bore into the workpiece 6 against the element 2 which is rotationally symmetrical with respect to the bore axis. The element 2, which is rotationally symmetrical to the bore axis, can be formed by a shaft or a cover element. As a result, the final position of the safety wire ring 1 in the position shown in FIG. 1b is reached when the assembly process is complete.
Die in Figur 2 im Querschnitt dargestellte Sicherungs¬ hülse 4 weist an ihrer Stirnseite 3, die beim Montage¬ vorgang dem aus der Zeichnung nicht ersichtlichen, zur Bohrungsachse rotationssy metrischen Element zugewandt ist, eine Auεstanzung 7 auf. Diese Ausstanzung 7 ent¬ steht dadurch, daß aus der napfförmigen Sicherungshülse 4 an ihrer Stirnseite 3 der Napfboden ausgestanzt ist. Während des Montagevorganges wird ein zur Bohrungsachse rotationssymmetrisches Element 2 zugeführt, das wie aus Figur 1 ersichtlich ist, an seiner der Sicherungshülse 4 zugewandten Seite konisch abgeflacht ist und mit ei¬ nem in diesem Bereich geringeren Durchmesser in die Ausstanzung 7 der Sicherungshülse 4 trifft. Die Siche¬ rungshülse 4 weist in ihrem dem zur Bohrungsachse rota¬ tionssymmetrischen Element 2 zugewandten Bereich eine konzentrische Abwinkelung von ca 45° zur - auf die Zeichnung bezogen - Horizontalen auf. Diese ist erforderlich, da die Sicherungshülse 4 während des Mon¬ tagevorganges bündig mit der Innenumwandung der Werk¬ stücksbohrung eingeführt wird und daher die Sicherungs¬ hülse 4 in ihrem oberen Bereich eine Ausformung aufwei¬ sen muß, die genügend Raum für den in diesem Bereich der Sicherungshülse (4) aufliegenden Sicherungs- drahtring 1 läßt, um in der Endphase des Montagevorgan¬ ges ein Einrasten dieses Sicherungsdrahtringes 1 in der Ringnut 5 bewirken zu können.The securing sleeve 4 shown in cross section in FIG. 2 has a punched-out portion 7 on its end face 3, which faces the element which is not evident from the drawing and is rotationally symmetrical to the bore axis during the assembly process. This punching 7 is due to the fact that the cup base is punched out of the cup-shaped securing sleeve 4 on its end face 3. During the assembly process, an element 2, which is rotationally symmetrical with respect to the bore axis, is fed in, as can be seen in FIG. The securing sleeve 4 has, in its area facing the element 2 rotationally symmetrical to the bore axis, a concentric bending of approximately 45 ° to the horizontal - based on the drawing. This is necessary because the securing sleeve 4 is inserted flush with the inner wall of the workpiece bore during the assembly process and therefore the securing sleeve 4 must have a shape in its upper area which has sufficient space for the in this area Securing sleeve (4) wire ring 1, in order to be able to cause this locking wire ring 1 to snap into the annular groove 5 in the final phase of the assembly process.
Eine mögliche Blockierung des Sicherungsdrahtringes 1 während des Montagevorganges wird aufgrund der Ausfor¬ mung des zur Bohrungsachse rotationssymmetrischen Ele¬ ments 2 Rechnung getragen, da dieses in seinem der Si¬ cherungshülse 4 zugewandten Bereich eine konische Ab- flachung aufweist und mit verringertem Durchmesser in die Sicherungshülse 4 trifft. A possible blocking of the locking wire ring 1 during the assembly process is taken into account on the basis of the shape of the element 2 which is rotationally symmetrical to the bore axis, since this has a conical flattening in its area facing the locking sleeve 4 and has a reduced diameter in the locking sleeve 4 hits.
