Description

Bewegungsbereich des Kugelkäfigs, worauf eine mechanische Zerstörung der Dichtung erfolgt. In allen bekannten Bauarten sind die Befestigungs- bzw. Spannelemente dem Angriff der verschiedensten Schmiermittel ausgesetzt. In einigen Einbauzuständen unterliegen sie auch dem Korrosionsangriff von Wasser. Insbesondere zeigen sich bei dem Angriff von Wasser schon nach verhältnismäßig kurzer Betriebszeit Störungen, die zu einem Ausfall des Wälzlagers führen. Movement range of the ball cage, whereupon the seal is mechanically destroyed. In all known designs, the fastening or clamping elements are exposed to the attack of the most varied of lubricants. In some installation conditions, they are also subject to the corrosive attack of water. In particular, already show up in the attack of water after a relatively short period of operation disorders that lead to failure of the bearing.

Es ist deshalb die Aufgabe der Erfindung, einen Dichtring für Wälzlager zu schaffen, der in seinen Abmessungen so klein gehalten ist, daß er mit dem Wälzlager zu einer baulichen Einheit vereinigt werden kann. Diese Dichtringe sollen jedoch die Mängel der bekannten Deckscheiben nicht mehr aufweisen und insbesondere ein Federlement enthalten, welches gegen den Angriff von Schmiermitteln und "asser völlig geschützt.ist, um somit über längere Zeit eine Federwirkung bzw. eine konstante Anpreßkraft in der Dichtfläche zu erreichen. Dieser Dichtring muß ferner so ausgebildet sein, daß seine Dichtheit am Einspannfuß garantiert ist, In der Dichtfläche, in der Relativbewegung auftritt, muß eine konstante Anpreßkraft über lange Zeit und über einen bestimmten Federweg erreicht werden. Diese Anpreßkraft muß einerseits genügen, um eine zuverlässige Schmiermitteldicht- Fi.g:-4`eine Draufsicht auf den erfindungsgemäßen Dichtring von der Kugellagerinnenseite aus; Fig. 5 einen Schnitt gemäß der Linie V-V in Fig. 4 in vergrößertem Maßstab; Fig. 6 eine besondere Ausbildungsform des Einspannfußes ; Fig. 7 eine weitere Ausführungsmöglichkeit des Ein-Spannfußes; Fig. 8 einen Halbschnitt ähnlich wie in Fig. 1, jedoch mit einem Dichtring, der auf dem Innenring eingespannt ist; Fig. 9 zwei Ausbildungsmöglichkeiten der Ringscheibenfedern, wie sie bei den in Fig. 8 gezeigten Dichtringen Verwendung finden; Fig.10 eine Seitenansicht von Fig. 9. It is therefore the object of the invention to provide a sealing ring for roller bearings which is kept so small in its dimensions that it can be combined with the roller bearing to form a structural unit. However, these sealing rings should no longer have the deficiencies of the known cover disks and in particular contain a spring element which is completely protected against attack by lubricants and water in order to achieve a spring effect or a constant contact pressure in the sealing surface over a longer period of time. this sealing ring has to be further adapted so that its tightness is guaranteed at Einspannfuß occurs in the sealing surface, in the relative movement, a constant contact force over a long period and over a certain travel must be achieved. this contact pressure has on the one hand sufficient to provide a reliable lubricant sealing - Fi.g: -4` a plan view of the sealing ring according to the invention from the inside of the ball bearing ; FIG. 5 shows a section along the line VV in FIG. 4 on an enlarged scale; FIG. 6 shows a particular embodiment of the clamping foot ; 7 shows a further possible embodiment of the clamping foot; FIG. 8 shows a half section similar to FIG. 1, but with a sealing ring which is clamped on the inner ring; FIG. FIG. 9 shows two possible designs of the annular disk springs as they are used in the sealing rings shown in FIG. 8; FIG. FIG. 10 is a side view of FIG. 9.

In Fig. 1 ist ein Rillenkugellager teilweise dargestellt, welches einen Innenring 1 und einen Außenring 2 aufweist. Die Kugeln 3 werden von einem Käfig 4 auf Abstand gehalten. Im Außenring 2 ist eine Nut 5 für die Aufnahme des Dicht- ringes 6 vorgesehen. Auch der Innenring 1 weist eine Nut, Anlagefläche od.dergl. 7 auf. In Fig. 1, a deep groove ball bearing is partially shown, which has an inner ring 1 and an outer ring 2. The balls 3 are held at a distance by a cage 4. A groove 5 for receiving the sealing ring 6 is provided in the outer ring 2. The inner ring 1 also has a groove, contact surface or the like. 7 on.

Der Dichtring 6 ist im wesentlichen aus einer Dichtungs- membran 8 aus elastischem Material gebildet. Die Dichtungs- The sealing ring 6 is essentially formed from a sealing membrane 8 made of elastic material. The sealing
