Abstract
Description
Lagerungsvorrichtung für eine WelleStorage device for a shaft
Stand der Technik Die Erfindung geht aus von einer Lagerungsvorrichtung nach der Gattung des Hauptanspruchs. Es sind schon Lagerungsvorrichtungen bekannt, bei denen ein Mitdrehen des Lageraußenrings in der Lagerbüchse durch geeignete Mittel verhindert wird. Solche Mittel sind Wellfederringe, 0-Ringe oder Kunststoffbuchsen. Bei der Anwendung solcher Mittel müssen einige Nachteile in Kauf genommen werden. So wie es beispielsweise das Lagerschild nicht ohne weiteres auf die Welle mit dem Lager aufsetzbar, weil ohne zusätzliche Maßnahmen bei der Montage die Luft in der Lagerbüchse gestaut würde. Außerdem wird die Reibung zwischen dem Kugellageraußeinring und der Innenwand der Lagerbüchse nicht im gewünschten Maß erhöht.PRIOR ART The invention is based on a storage device according to the genre of the main claim. Storage devices are already known in which the bearing outer ring rotates in the bearing bush by suitable means is prevented. Such means are corrugated spring washers, O-rings or plastic bushings. When using such agents, some disadvantages must be accepted. Just as it is, for example, the end shield does not simply fit onto the shaft with the The bearing can be fitted because there is no additional air in the assembly during assembly Bearing bush would be jammed. It also reduces the friction between the ball bearing outer ring and the inner wall of the bearing bush is not increased to the desired extent.
Schließlich muß die Wandstärke der Lagernabe am gesamten Umfang der Lagerbüchse erhöht werden.Finally, the wall thickness of the bearing hub must be on the entire circumference of the Bearing bush can be increased.
Vorteile der Erfindung Die erfindungsgemäße Vorrichtung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß die Auflagefläche des Lagers in der Lagerbüchse nur geringfügig verringert ist. Als weiterer Vorteil ist anzusehen, daß die Wandstärke der Lagernabe nicht auf den gesamten Umfang erhöht werden muß.Advantages of the invention The device according to the invention with the characterizing Features of the main claim has the advantage that the support surface of the bearing in the bearing bush is only slightly reduced. Another advantage can be seen that the wall thickness of the bearing hub does not cover the entire Scope needs to be increased.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Vorrichtung möglich. Besonders vorteilhaft ist, daß kein Luftstau und keine Pumpwirkung auftritt und daß ohne weiteres ein Luftausgleich möglich ist. Die Montage ist problemlos. Die keilförmige oder prismatische Ausführung des Dämpfungselements oder der Dämpfungselemente erhöht die Reibung beim Drehen des Lageraußenrings gegenüber den herkömmlichen Mitteln beträchtlich.The measures listed in the subclaims are advantageous Developments and improvements of the device specified in the main claim possible. It is particularly advantageous that there is no accumulation of air and no pumping action and that an air balance is easily possible. The assembly is easy. The wedge-shaped or prismatic design of the damping element or elements increases the friction when turning the bearing outer ring compared to conventional means considerably.
Zeichnung Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Figur 1 zeigt einen Querschnitt durch eine Lagerbüchse, die Figuren 2 und 3 mögliche Querschnitte der Dämpfungsmittel, die Figuren 4 und 5 die Dämpfungsmittel in eingebautem Zustand.Exemplary embodiments of the invention are shown in the drawing and explained in more detail in the following description. Figure 1 shows a cross section through a bearing bush, Figures 2 and 3 possible cross sections the damping means, FIGS. 4 and 5 show the damping means in the installed state.
Beschreibung der Ausführungsbeispiele In Figur 1 ist eine Lagernabe mit einer Lagernabe 11 gezeigt, in die ein Wälzlager mit einem Außenring 12 eingesetzt ist. In die Lagerbüchse 11 ist eine Keilnut 13 mit einem trapezförmigen Querschnitt eingebracht.Description of the exemplary embodiments In FIG. 1 there is a bearing hub shown with a bearing hub 11 into which a roller bearing with an outer ring 12 is inserted is. In the bearing bush 11 is a keyway 13 with a trapezoidal cross-section brought in.
Figur 2 zeigt als ein erstes Beispiel ein Dämpfungselement 14, das einen eben wesentlichen trapezförmigen Querschnitt mit angeformten Lippen 15 aufweist. In Figur 3 ist als Dämpfungselement eine Ausführungsform 16 mit einem Querschnitt eines gleichseitigen Dreiecks vorgestellt. Die Dämpfungselemente 14, 16 aus einem elastischen Material hergestellt, daß gleichzeitig schwingungsdämpfend wirkt.As a first example, FIG. 2 shows a damping element 14 which has a substantially trapezoidal cross-section with lips 15 molded on. In Figure 3 is an embodiment 16 with a cross section as a damping element of an equilateral triangle. The damping elements 14, 16 from one made of elastic material that at the same time has a vibration-damping effect.
In Figur 4 ist eine Lagerungsvorrichtung gezeigt, bei der ein Dämpfungsmittel 14 nach Figur 2 verwendet ist.In Figure 4, a storage device is shown in which a damping means 14 of Figure 2 is used.
Figur 5 zeigt die Verwendung eines Dämpfungsmittels 16 nach Figur 3.FIG. 5 shows the use of a damping means 16 according to FIG 3.
Die Keilnut 13 erstreckt sich vorzugsweise über die gesamte Breite der Lagerbüchse 11. Im Umfang der Lagerbüchse 11 können eine oder mehrere Keilnuten 13 angeordnet sein.The keyway 13 preferably extends across the entire width of the bearing bush 11. In the circumference of the bearing bush 11, one or more keyways can be used 13 be arranged.
Die Dämpfungsmittel 14, 16 dämpfen Schwingungen des Wälzlagers 12 und verhindern ein Mitdrehen des äußeren Lagerrings 12 in der Lagerbüchse 11.The damping means 14, 16 dampen vibrations of the roller bearing 12 and prevent the outer bearing ring 12 from rotating in the bearing bush 11.
