Abstract

A component (4) which is located on a rotating shaft (3) is axially secured by a circlip (1) which is retained in an external shaft groove (2). In order to prevent circlip expansion due to centrifugal forces, a closed retaining ring (5) is placed over the circlip. The retaining ring (5) is provided with an axial collar whose profile matches the external circlip profile. The outside end of the retaining ring (5) is provided with an internal ring groove (6) for the location of a radially-corrugated spring clip (8). The inside ends of the spring clip corrugations are located in a ring groove (7) on the shaft in order to secure the retaining ring installations. USE/ADVANTAGE Circlip location on rotating shaft is secured against expansion by simple, shaft mounted retaining ring.

Description

Die Erfindung betrifft die Sicherung eines radial geschlitzten Wellen-Sicherungsringes gegen fliehkraftbedingtes Aufweiten.The invention relates to securing a radially slotted Shaft circlip against centrifugal expansion.

Eine solche Sicherung ist zur Vermeidung eines Aufweitens des Wellen-Sicherungsringes bei hohen Drehzahlen aus DE-U-75 35 901 bekannt. Dort ist über einen radial geschlitzten Wellen-Sicherungsring ein geschlossener Ring außen formschlüssig aufgestülpt. Da dieser aufgestülpte Ring eine innen durchgehende axial hinterschnittfreie Umfangsfläche in gleicher Weise wie der gegen Aufweiten zu sichernde Wellen-Sicherungsring aufweist, ist eine axiale Fixierung des aufgestülpten Ringes notwendig. Dies geschieht dadurch, daß dieser Aufstülp-Ring an seiner einen Seite an der Nabe anliegt, in der die Welle gelagert ist, und auf der anderen Seite durch einen außen spannenden in der Nabenbohrung fixierten Sprengring gesichert ist. Es sind hier also insgesamt zwei Ringe erforderlich, und zwar einmal der geschlossene Aufstülp-Ring und zum anderen noch zusätzlich ein außenspannender Sprengring, der außerhalb der Welle gelagert werden muß.Such a backup is to avoid expanding the Shaft circlip at high speeds from DE-U-75 35 901 known. There is a radially slotted shaft retaining ring a closed ring is positively put on the outside. Because this put on ring is continuous on the inside axially undercut-free peripheral surface in the same way as which has a shaft circlip to be secured against expansion, is an axial fixation of the slipped ring necessary. This happens because this slip-on ring one side abuts the hub in which the shaft is mounted is, and on the other hand by an outside exciting snap ring fixed in the hub bore is secured. It a total of two rings are required here on the one hand the closed slip-on ring and on the other hand additionally an external snap ring that is outside the Shaft must be stored.

Hier eine Vereinfachung zu schaffen, ist die Aufgabe der vorliegenden Erfindung. Außerdem soll die Sicherung nicht außerhalb der Welle angebracht werden müssen. The task of the present is to create a simplification here Invention. In addition, the fuse should not be outside the shaft must be attached.  

Gelöst wird diese Aufgabe durch eine Ausführung des aufzustülpenden Sicherungsringes nach den kennzeichnenden Merkmalen des Patentanspruchs 1.This task is solved by executing the one to be put on Circlip according to the characteristic features of the Claim 1.

Eine zweckmäßige Ausgestaltung der Erfindung ist Gegenstand des Unteranspruchs. Ein Ausführungsbeispiel ist in der Zeichnung dargestellt.A practical embodiment of the invention is the subject of the subclaim. An embodiment is shown in the drawing.

Es zeigt:It shows:

Fig. 1 eine Wellensicherung als Ausschnitt aus einem Längsschnitt, Fig. 1 shows a shaft lock as a segment of a longitudinal section,

Fig. 2 eine Draufsicht auf die Wellensicherung in Richtung auf das freie Ende der Welle, Fig. 2 is a plan view of the shaft lock in the direction of the free end of the shaft,

Fig. 3 den Stoßbereich des Wellensicherungsringes als Ausschnitt einer Draufsicht auf den Wellensicherungsring in Richtung des Pfeiles III, Fig. 3 shows the joint region of the shaft securing ring as a section of a top view of the circlip in the direction of arrow III,

Fig. 4 eine alternative Querschnittsform des Überstülp-Ringes in einer Darstellung nach Fig. 1. Fig. 4 shows an alternative cross-sectional shape of the Überstülp ring in an illustration in FIG. 1.

Ein innenspannender radial geschlitzter Wellen-Sicherungsring 1 sitzt in einer Ringnut 2 einer Welle 3, wobei er sich axial an einem Ende an einer die Welle lagernden Nabe 4 und an dem anderen Ende innerhalb der Ringnut 2 abstützt.An internally clamping, radially slotted shaft retaining ring 1 is seated in an annular groove 2 of a shaft 3 , being axially supported at one end on a hub 4 supporting the shaft and at the other end within the annular groove 2 .

Gegen ein fliehkraftbedingtes Aufweiten, das bei hohen Drehzahlen eintreten kann, ist der Wellen-Sicherungsring 1 durch einen Überstülp-Ring 5 gesichert. The shaft retaining ring 1 is secured by a slip ring 5 against expansion caused by centrifugal force, which can occur at high speeds.

Dieser Ring ist ein gebördelter Blechring, der an einem seiner axialen Enden formschlüssig auf dem Außenumfang des Wellen-Sicherungsringes 1 anliegt. An seinem axial zweiten Ende ist eine zur Welle 3 weisende Umfangs-Sicherungsrille 6 eingeformt. Gegenüberliegend dieser Sicherungsrille 6 des Überstülpringes 5 ist eine entsprechende Wellen-Sicherungsrille 7 vorgesehen. In diese beiden gegenüberliegenden Sicherungsrillen 6, 7 greift ein über den Umfang unrund geformter Schnapp-Federring 8 abwechselnd über dem Umfang verteilt ein. Dadurch ist der Überstülp-Ring 5 axial fixiert. Der Federring 8 kann an den Stellen, an denen er in dem Überstülp-Ring anliegt, fest mit dem Überstülp-Ring 5 verbunden werden. In diesem Fall kann der Überstülp-Ring 5 zusammen mit dem Federring 8 als ein Teil auf die Welle aufgezogen werden, wobei der Federring 8 in die Sicherungsrille 7 der Welle 3 einschnappen kann.This ring is a flanged sheet metal ring which rests on one of its axial ends in a form-fitting manner on the outer circumference of the shaft retaining ring 1 . At its axially second end, a circumferential securing groove 6 facing the shaft 3 is formed. A corresponding shaft securing groove 7 is provided opposite this securing groove 6 of the slip ring 5 . In these two opposite securing grooves 6, 7 , a snap spring ring 8, which is non-circular in shape , engages alternately distributed over the circumference. As a result, the slip ring 5 is axially fixed. The spring ring 8 can be firmly connected to the slip ring 5 at the points at which it rests in the slip ring. In this case, the slip ring 5 can be pulled together with the spring ring 8 as a part onto the shaft, the spring ring 8 being able to snap into the securing groove 7 of the shaft 3 .

Die Ausführung des Überstülp-Ringes 5 nach Fig. 1, bei der die Sicherungsrille 6 durch ein Ausformen des Überstülp-Ringes nach radial außen über den Durchmesser des an dem Wellen-Sicherungsring 1 anliegenden Bereiches hinaus erfolgt, stellt eine axial raumsparende Form dar.The embodiment of the slip ring 5 according to FIG. 1, in which the securing groove 6 is formed by shaping the slip ring radially outward beyond the diameter of the area adjoining the shaft securing ring 1 , represents an axially space-saving shape.

Kommt es dagegen auf eine radial raumsparende Ausführung an, so ist der die Sicherungsrille 6 enthaltende Teil des Überstülp-Ringes 5 nach radial innen unter den Außendurchmesser des Wellen-Sicherungsringes 1 entsprechend Fig. 4 einzuziehen.If, on the other hand, it is a matter of a radially space-saving design, the part of the slip ring 5 containing the securing groove 6 is to be drawn in radially inward under the outer diameter of the shaft securing ring 1 according to FIG. 4.
