Description
DEUTSCHESGERMAN
Es sind Sicherungen gegen axiale Verschiebung bzw. zum Ausschalten axialen Endspiels von in einer
Bohrung gelagerten Konstruktionsteilen bekannt, bestehend aus einem in eine Nut der Bohrung eingesetzten
geschützen, federnden, kegelförmigen Ring mit radial und auf einer Kegelmantelfläche angeordneten
Lappen. Solche Sicherungsringe müssen, da ihr Außendurchmesser größer ist als der Bohrungsdurehmesser,
unter beträchtlicher elastischer Zusammendrückung, also unter elastischer radialer Vorspannung,
zu ihren Sitzen in der Bohrung gebracht werden. Diese durch Kräfte an den Ringenden ausgeübte elastische
Verformung macht die ungleichmäßige Bemessung des Ringes (er ist in der Mitte am breitesten und
nimmt nach den Enden hin stetig ab) erforderlich, damit er auch im verformten Zustand seine geometrische
Ringform möglichst beibehält. Nach Entlastung springt der Ring infolge seines Bestrebens, seine ursprüngliche
Form wieder anzunehmen, unter Aufweitung in die ihm als Sitz bestimmte Nut, schiebt
sich keilartig zwischen eine Schulter dieser Nut und eine Gegenfläche des benachbarten Konstruktionsteiles
und übt dabei einen axialen Druck aus bzw. hebt unter Ausübung geringen axialen Druckes bestehendes
axiales Spiel auf. Bei diesen Sicherungsringen sind der eigentliche Ringkörper und die nach
innen gerichteten Lappen nur schwach kegelförmig ausgebildet (bei den bekanntgewordenen praktischen
Ausführungen sind die Lappen dazu in entgegengesetzter Richtung gebogen wie der eigentliche Ringkörper).
Diese Sicherungen für Bohrungen bis zu 100 mm Durchmesser ermöglichen daher nur, axiales
Spiel von 0,2 mm bis maximal etwa 0,5 mm auszugleichen. Infolge ihrer unterschiedlichen Breite sind
sie auch nicht imstande, mittels ihrer Lappen gleich große (oder wenigstens annähernd gleich große)
Kräfte in axialer Richtung auszuüben. Außerdem ist ihr Einsetzen bei gleichzeitiger elastischer radialer
Verformung umständlich und häufig mit Schwierigkeiten verbunden. Es ist ferner bekannt, ein
Maschinenelement in der Bohrung eines Maschinenteiles durch ein zweckmäßig aus einem härteren Werkstoff
bestehendes Spreizelement sicherzustellen. Man hat auch schon vorgeschlagen, Kolbenbolzen in ihrem
Lager durch Sicherungskörper axial festzustellen, die ursprünglich (d. h. vor dem Einbringen in den
sichernden Sitz) aus mit einem Sektorauschnitt versehenen ebenen Kreis- oder Kreisringscheiben bestehen,
die beim Einsetzen in die Lagerbohrung zum Kegelmantel bzw. Kegelstumpfmantel bleibend verformt
werden, dessen gegebenenfalls mit Zacken oder Zähnen versehener Grundkreis in einer Rille in der
Lagerbohrung einrastet. Das Verformen dieser SicherungskÖrper beim Einbringen in ihren Sitz ist jedoch,
Federnder, kegelförmiger offener
Sicherungsring mit innenliegenden LappenThere are known safeguards against axial displacement or for eliminating axial end play of structural parts mounted in a bore, consisting of a protected, resilient, conical ring with radially arranged tabs on a conical surface, inserted into a groove in the bore. Since their outer diameter is larger than the bore diameter, such circlips must be brought to their seats in the bore under considerable elastic compression, that is to say under elastic radial prestress. This elastic deformation exerted by forces on the ring ends makes the uneven dimensioning of the ring (it is widest in the middle and steadily decreasing towards the ends) necessary so that it retains its geometric ring shape as much as possible even in the deformed state. After relieving the load, the ring, as a result of its attempt to take on its original shape again, jumps into the groove intended for it as a seat, pushes itself in a wedge-like manner between a shoulder of this groove and a counter surface of the adjacent structural part and exerts an axial pressure or lifts under Exercise of low axial pressure on existing axial play. In these circlips, the actual ring body and the inwardly directed tabs are only slightly conical (in the practical designs that have become known, the tabs are bent in the opposite direction to the actual ring body). These securing devices for bores up to 100 mm in diameter therefore only make it possible to compensate for axial play of 0.2 mm to a maximum of about 0.5 mm. As a result of their different widths, they are also unable to exert forces of the same size (or at least approximately the same size) in the axial direction by means of their lobes. In addition, their insertion with simultaneous elastic radial deformation is cumbersome and often associated with difficulties. It is also known to secure a machine element in the bore of a machine part by means of an expansion element which is expediently made of a harder material. It has also already been proposed to axially determine the piston pin in its bearing by means of securing bodies, which originally (i.e. before being inserted into the securing seat) consist of flat circular or circular ring disks provided with a sector cut-out, which when inserted into the bearing bore to the surface of the cone or truncated cone are permanently deformed, whose base circle, optionally provided with prongs or teeth, engages in a groove in the bearing bore. The deformation of these securing bodies when they are introduced into their seat is, however, more resilient, more cone-shaped

insbesondere bei größerer Blechdicke, umständlich und bietet keine Gewähr dafür, daß der Grundkreis stets in einer Ebene liegt und in allen Punkten seines Umfanges einen annähernd gleichmäßigen axialen Druck hervorruft.especially with thicker sheet metal, cumbersome and does not guarantee that the base circle always lies in one plane and an approximately uniform axial plane in all points of its circumference Pressure.
Die Erfindung bezweckt, eine Sicherung für Bohrungen zu schaffen, die nicht wie die auf dem Markt befindlichen Sicherungsringe nur geringes axiales Spiel unter leichtem Andruck ausgleicht, sondern beträchtliche axiale Verspannungen durch möglichst gleichmäßig verteilte Axialkräfte unter Ausgleich größeren axialen Spiels zu erzeugen gestattet. Die Erfindung geht dabei aus von einem federnden, kegelförmigen offenen Sicherungsring mit innenliegenden Lappen, der in die Nut einer Bohrung eingesetzt wird und die Axialverschiebung eines Teiles in der Bohrung verhindert, und ist gekennzeichnet durch die Kombination folgender Merkmale:The invention aims to provide a fuse for bores to create, which is not like the retaining rings on the market only slight axial Compensates play under light pressure, but rather considerable axial tension through as much as possible Allowed to generate evenly distributed axial forces while compensating for larger axial play. The invention is based on a resilient, conical open locking ring with an internal Flap that is inserted into the groove of a hole and the axial displacement of a part in the hole prevented, and is characterized by the combination of the following features:
1. Der Außendurchmesser des unbelasteten Ringes ist etwas kleiner als der Durchmesser der Bohrung. 2. Der Abstand der Nutkante, an der der eingesetzte Ring anliegt, von der Gegenfläche des gesicherten Teiles ist kleiner als die Höhe des unbelasteten Ringes.1. The outside diameter of the unloaded ring is slightly smaller than the diameter of the bore. 2. The distance between the groove edge on which the inserted ring rests and the opposite surface of the secured one Part is smaller than the height of the unloaded ring.
Der erfindungsgemäße Sicherungsring bildet in seiner ganzen Breite, einschließlich seiner Lappen, im unbelasteten Zustand die Mantelfläche eines Kegelstumpfes von verhältnismäßig kleinem Kegelwinkel, The locking ring according to the invention forms in its entire width, including its lobes, in the unloaded state the lateral surface of a truncated cone with a relatively small cone angle,
