Wälzlager mit stirnseitiger AbdeckkappeRolling bearing with a cover cap on the face

Die Erfindung betrifft ein Wälzlager mit stirnseitiger Abdeckkappe, die am Wälzlageraußenring befestigt ist.The invention relates to a roller bearing with an end cap, which is attached to the roller bearing outer ring.

Bekannte derartige Abdeckkappen sind üblicherweise mit einem radial nach außen gerichteten Rand in einer Umfangsnut des äußeren Wälzlagerlaufringes befestigt. Sie dienen teils dazu, das Lagerinnere gegen Schmutzeintritt abzudekken, teils auch dazu, einen Berührungsschutz gegen das umlaufende Ende der in dem Lager gelagerten Welle zu bilden. An der Lagerseite, an der die Abdeckkappe angeordnet ist, ist bei diesen bekannten Lagern auf eine sonstige Lagerabdichtung verzichtet. Dies führt in vielen Fällen dazu, daß bei zunehmender Lagererwärmung das zur Lagerschmierung dienende Fett aus dem Lager abfließt und sich in der Abdeckkappe ansammelt. Eine ausreichende Lagerschmierung ist damit nicht mehr gewährleistet. Die Anbringung einer zusätzlichen Lagerabdichtung bei solchen Lagern scheitert in der Praxis meist am dafür erforderlichen Platzbedarf. Es wäre hierzu erforderlich, den Außenlaufring in axialer Richtung zu verlängern, um genügend Bauraum für die Befestigung der weiteren Abdichtung zu schaffen. Dieser zusätzlich benötigte axiale Bauraum steht in vielen Anwendungsfällen jedoch nicht zur Verfügung. Known such cover caps are usually with a radially outwardly directed edge in a circumferential groove of the outer roller bearing race. You serve partly to cover the inside of the bearing against the ingress of dirt, partly also to form a contact protection against the circumferential end of the shaft mounted in the bearing. On the bearing side on which the cover cap is arranged, in these known bearings there is another bearing seal waived. In many cases, this leads to bearing lubrication as the bearing heats up Serving grease flows out of the bearing and collects in the cover cap. Adequate bearing lubrication is thus no longer guaranteed. The attachment of an additional bearing seal in such bearings fails in practice mostly on the space required for this. This would require the outer race in an axial Direction to lengthen in order to create enough space for the attachment of the further seal. This one in addition However, the required axial installation space is not available in many applications.

Aufgabe der Erfindung ist es, ein derartiges Wälzlager zu schaffen, bei dem ohne zusätzlichen Platzbedarf zusätzlich zu der stirnseitigen Abdeckkappe eine Lagerabdichtung untergebracht werden kann.The object of the invention is to create a roller bearing of this type in which, without additional space requirements, a bearing seal can be accommodated for the end cap.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß der Wälzlageraußenring in einer Ausnehmung einen mit dem Wälzlagerinnenring zusammenwirkenden Dichtring aufnimmt, der seinerseits eine umlaufende Nut aufweist, in die die Abdeckkappe mit einem umlaufenden Rand eingeschnappt ist. Die Lösung der gestellten Aufgabe kann alternativ auch derart erfolgen, daß der Walzlageraußenring in einer Ausnehmung den umlaufenden Rand der Abdeckkappe aufnimmt, die ihrerseits eine umlaufende Innennut besitzt, in die ein mit dem Wälzlagerinnenring zusammenwirkender Dichtring eingesetzt ist. Beiden Lösungen ist gemeinsam, daß am Wälzlageraußenring stets nur eine einzige Ausnehmung (Umfangsnut) vorgesehen werden muß, so daß der Wälzlageraußenring in seinen Abmessungen und seinem Querschnitt völlig einem solchen Walzlageraußenring entspricht, wie er für ein einfaches abgedichtetes Wälzlager verwendet wird. Es kann also dasselbe Wälzlager wahlweise entweder nur mit einer einfachen gleitenden Abdichtung oder auch zusätzlich mit einer stirnseitigen Abdeckkappe versehen werden.This object is achieved according to the invention in that the roller bearing outer ring in a recess with the one Roller bearing inner ring receives cooperating sealing ring, which in turn has a circumferential groove into which the Cover cap is snapped into place with a circumferential edge. The solution to the given task can alternatively also take place in such a way that the roller bearing outer ring receives the circumferential edge of the cap in a recess, which in turn has a circumferential inner groove into which a sealing ring cooperating with the roller bearing inner ring is inserted is. Both solutions have in common that there is always only a single recess (circumferential groove) on the roller bearing outer ring. must be provided so that the roller bearing outer ring in its dimensions and its cross-section completely one corresponds to such a roller bearing outer ring as it is used for a simple sealed roller bearing. So it can the same roller bearing either with only a simple sliding seal or also with one be provided on the front cover cap.

Nach einer bevorzugten Ausführungsform besitzt der Wälzlageraußenring nahe seinem stirnseitigen Ende in seiner Bohrung eine umlaufende Nut, in die ein Dichtring aus elastischem Werkstoff, wie Gummi, Kunststoff oder dergleichen eingreift, der mit einem axial gerichteten Kragen den Wälzlageraußenring stirnseitig überragt und in diesem Abschnitt eine umlaufende Nut aufweist, in die ein radial gerichteter Rand der Abdeckkappe formschlüssig eingreift.According to a preferred embodiment, the roller bearing outer ring has near its front end in its bore a circumferential groove into which a sealing ring made of elastic Material, such as rubber, plastic or the like, engages the roller bearing outer ring with an axially directed collar protrudes at the end and in this section has a circumferential groove into which a radially directed The edge of the cap engages positively.

Ausführungsbeispiele der Erfindung sind in den Zeichnungen im Längsschnitt dargestellt.Embodiments of the invention are shown in the drawings in longitudinal section.

Gemäß Figur 1 ist auf der Welle 1 der Wälzlagerinnenring 2 mittels eines Exzenterspannringes 3 befestigt. Zwischen dem Innenring 2 und dem Wälzlageraußenring 4, der in dem Gehäuse 5 untergebracht ist, rollen die Kugeln 6 ab. Nahe seinem stirnseitigen Ende weist der Wälzlageraußenring 4 eineAccording to FIG. 1, the roller bearing inner ring 2 is fastened to the shaft 1 by means of an eccentric clamping ring 3. Between the The balls 6 roll off the inner ring 2 and the roller bearing outer ring 4, which is accommodated in the housing 5. Near his the front end of the roller bearing outer ring 4 has a

Umfangsnut 7 auf, in welche der Dichtring 8, der mit dem Wälzlagerinnenring 2 abdichtend zusammenwirkt, eingesetzt ist. Der Dichtring 8 ist mit einem den Wälzlageraußenring 4 stirnseitig überragenden Ansatz 9 versehen, der seinerseits wiederum eine Umfangsnut 1o besitzt. In diese Umfangsnut 1o greift der radiale Rand 11 der Abdeckkappe 12 formschlüssig ein.Circumferential groove 7, in which the sealing ring 8, which cooperates in a sealing manner with the roller bearing inner ring 2, is inserted is. The sealing ring 8 is provided with a projection 9 protruding on the end face of the roller bearing outer ring 4, which in turn in turn has a circumferential groove 1o. In this circumferential groove 1o the radial edge 11 of the cap 12 engages in a form-fitting manner.

Bei der in Figur 2 in einem Ausschnitt dargestellten Variante greift in die Umfangsnut 7 des Wälzlageraußenringes 4 ein umlaufender Rand 13 der Abdeckkappe 14 ein. Im Bereich des Randes 13 weist die Abdeckkappe 14 in ihrer Bohrung eine weitere Umfangsnut 15 auf, in die ein Dichtring 16 formschlüssig eingreift, der mit dem Wälzlagerinnenring 2 abdichtend zusammenwirkt.In the variant shown in a section in FIG. 2, it engages in the circumferential groove 7 of the roller bearing outer ring 4 a circumferential edge 13 of the cap 14. In the area of the edge 13, the cap 14 has its bore a further circumferential groove 15 into which a sealing ring 16 engages in a form-fitting manner, which with the roller bearing inner ring 2 cooperates sealingly.
