Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft ein Wälzlager mit zwei koaxial zueinander angeordneten Lagerringen mit zwischen diesen in einem radialen Zwischenraum abwälzenden Wälzkörpern und einer den Zwischenraum an zumindest einer Stirnseite des Wälzlagers nach außen abdichtenden Dichtung.The invention relates to a rolling bearing with two bearing rings arranged coaxially with one another with rolling elements rolling off between them in a radial gap and a seal which seals off the gap on at least one end face of the rolling bearing to the outside.
Hintergrund der ErfindungBackground of the invention
Gattungsgemäße Wälzlager mit zwei zueinander als Außen- und Innenring ausgebildeten Lagerringen und zwischen diesen auf entsprechenden Laufbahnen abwälzenden Wälzkörpern sind hinreichend bekannt. Zur Abdichtung eines radialen Zwischenraums der Lagerringe nach außen sind verschiedene Formen von Dichtungen bekannt. Beispielsweise ist aus der
Aufgabe der ErfindungObject of the invention
Aufgabe der Erfindung ist die vorteilhafte Weiterbildung eines Wälzlagers mit einer einfach herzustellenden drehfesten Anbindung einer Dichtung an einen Lagerring.The object of the invention is the advantageous development of a rolling bearing with a simple to produce rotationally fixed connection of a seal to a bearing ring.
Allgemeine Beschreibung der ErfindungGeneral description of the invention
Die Aufgabe wird durch den Gegenstand des Anspruchs 1 gelöst, die von dem Anspruch 1 abhängigen Ansprüche geben vorteilhafte Ausführungsformen des Gegenstands des Anspruchs 1 wieder.The object is solved by the subject matter of
Das vorgeschlagene Wälzlager enthält zwei koaxial zueinander angeordnete Lagerringe in Form eines ein- oder mehrteiligen Außenrings und eines einoder mehrteiligen Innenrings in Form eines Rillenkugellagers, Schrägkugellagers, Zylinderrollenlagers, Kegelrollenlagers, Tonnenrollenlagers, Nadellagers und dergleichen. Auf ein- oder mehrreihigen Laufbahnen wälzen dabei zwischen den Lagerringen Wälzkörper ab, so dass zwischen den Laufringen an einer oder beiden Stirnseiten ein nach außen offener radialer Zwischenraum zwischen den Laufringen vorgesehen ist. An zumindest einer Stirnseite des Wälzlagers ist zum Schutz beispielsweise gegen von außen eindringendes Wasser, Verschmutzungen wie Staub oder dergleichen eine nach außen abdichtende Dichtung vorgesehen. Die Dichtung ist gegenüber einem der Lagerringe mittels an einem Umfang der Dichtung verteilter elastischer Zähne an einem Gegenprofil des Lagerrings verliersicher und drehfest verkrallt. Auf diese Weise kann eine umlaufend konstante Befestigungskraft erzielt werden, so dass auf den Lagerring keine Befestigungskräfte wirken, die die Rundheit des Lagerrings negativ beeinflussen. Die Dichtung kann an einem als Innenring ausgebildeten Lagerring angeordnet sein und weist hierzu die Zähne am Innenumfang der Dichtung auf. In bevorzugter Weise ist die Dichtung jedoch an einem als Außenring ausgebildeten Lagerring angeordnet. Hierbei weist die Dichtung die über den Umfang verteilten Zähne an deren Außenumfang auf. The proposed rolling bearing comprises two coaxially arranged bearing rings in the form of a one- or multi-part outer ring and a one or multi-part inner ring in the form of a deep groove ball bearing, angular contact ball bearing, cylindrical roller bearing, tapered roller bearing, roller bearing, needle roller bearing and the like. Rolling bodies roll on single or multi-row tracks between the bearing rings, so that between the races on one or both end faces an outwardly open radial gap is provided between the races. On at least one end face of the rolling bearing is provided for protection against, for example, from the outside penetrating water, dirt such as dust or the like, a sealing gasket to the outside. The seal against one of the bearing rings by means of distributed on a circumference of the seal elastic teeth on a counter-profile of the bearing ring captive and rotatably locked. In this way, a circumferentially constant fastening force can be achieved, so that no fastening forces act on the bearing ring, which adversely affect the roundness of the bearing ring. The seal may be arranged on a bearing ring formed as an inner ring and has for this purpose the teeth on the inner circumference of the seal. Preferably, however, the seal is arranged on a bearing ring designed as an outer ring. In this case, the seal on the circumferentially distributed teeth on the outer circumference.
Die Dichtung ist gemäß einer bevorzugten Ausführungsform an einer axialen Anlagefläche des einen Lagerrings wie Außenring angelegt. Die über den Umfang bevorzugt lückenlos über den Umfang angeordneten Zähne sind hierbei nach radial außen umgelegt. Das Gegenprofil des Außenrings ist dabei aus einem axialen, radial erweiterten Hinterschnitt in einem axial die Dichtung umgreifenden Bereich des Außenrings gebildet. Durch die elastische Ausbildung der Zähne kann die Dichtung gegen die Anlagefläche gepresst und die Zähne können in den Hinterschnitt unter elastischer Verformung zu einem kleineren Durchmesser in den Hinterschnitt eingeschnappt beziehungsweise eingerastet werden. Die Zähne bilden an dem Hinterschnitt einen axialen Formschluss mit dem Außenring und verkrallen sich beim Einschnappen mit dem Außenring, so dass eine verliersichere und drehfeste Aufnahme der Dichtung an dem Außenring erfolgt. In ähnlicher Weise kann eine Dichtung mit einem entsprechenden Hinterschnitt eines Innenrings verbunden werden.The seal is applied according to a preferred embodiment of an axial bearing surface of a bearing ring as outer ring. The preferably over the circumference of the circumference circumferentially arranged teeth are hereby folded radially outward. The mating profile of the outer ring is formed from an axial, radially enlarged undercut in an axially surrounding the seal region of the outer ring. Due to the elastic design of the teeth, the seal can be pressed against the contact surface and the teeth can be snapped into the undercut with elastic deformation to a smaller diameter in the undercut or snapped. The teeth form on the undercut an axial positive engagement with the outer ring and digs when snapping with the outer ring, so that a captive and rotationally fixed receiving the seal is made on the outer ring. Similarly, a seal can be connected to a corresponding undercut of an inner ring.
Um beispielsweise den Bauraum des Zwischenraums zu erweitern, kann die Dichtung in einem Bereich des Zwischenraums axial nach außen erweitert sein. Bevorzugt fluchtet diese Erweiterung mit dem axial endseitigen Abschluss wie Stirnfläche des Außenrings, so dass eine im Wesentlichen plane Stirnseite des Wälzlagers erzielt wird.For example, to expand the space of the gap, the seal may be extended axially outwardly in a region of the gap. Preferably, this extension is aligned with the axial end-side termination as the end face of the outer ring, so that a substantially planar end face of the rolling bearing is achieved.
Die Dichtung kann aus Kunststoff beispielsweise mittels eines Spritzgussverfahrens hergestellt sein, in vorteilhafter Weise machen sich die Vorteile der vorgeschlagenen Dichtung insbesondere bei den wesentlich steifer ausgebildeten Dichtungen aus Metall bemerkbar. Eine derartige Dichtung kann aus Blech hergestellt, beispielsweise gestanzt und umformend, beispielsweise tiefgezogen oder in einer Matrize umgeformt hergestellt sein. The seal may be made of plastic, for example by means of an injection molding process, in an advantageous manner, the advantages of the proposed seal in particular in the much stiffer formed metal seals noticeable. Such a seal can be made of sheet metal, for example, punched and be formed, for example, deep-drawn or formed in a die formed.
Die Dichtung kann ringförmig ausgebildet sein und gegenüber dem anderen, radial gegenüberliegenden Lagerring, beispielsweise dem Innenring abgedichtet sein. Die Abdichtung kann mittels eines einfachen oder labyrinthförmigen Luftspalts gegenüber dem anderen Lagerring oder mittels einer dynamischen Dichtung erfolgen. Die dynamische Dichtung ist bevorzugt mittels zumindest einer Dichtlippe ausgebildet. Alternativ können polymere Dichtstoffe wie Kautschuk, Gummi oder dergleichen, Filz- und Faserstoffe oder dergleichen alternativ oder zusätzlich in anderer Form die dynamische Dichtung bilden.The seal may be annular and be sealed relative to the other, radially opposite bearing ring, for example, the inner ring. The sealing can be done by means of a simple or labyrinthine air gap relative to the other bearing ring or by means of a dynamic seal. The dynamic seal is preferably formed by means of at least one sealing lip. Alternatively, polymeric sealants such as rubber, rubber or the like, felt and fibrous or the like may alternatively or additionally form the dynamic seal in another form.
Alternativ zu einer ringförmigen Dichtung kann bei Aufnahme des Wälzlagers an einer abschließenden Welle oder Achse die Dichtung einen das Wälzlager an einer Stirnseite vollständig abdichtenden Deckel bilden, so dass wie beispielsweise bei Radlagern neben dem Zwischenraum auch der komplette Innenring an einer Stirnseite des Wälzlagers vollständig abgedeckt ist. An der gegenüberliegenden Seite kann eine entsprechend ringförmig ausgebildete Dichtung vorgesehen sein. Es versteht sich, dass an durchgehenden Wellen oder Achsen an beiden Stirnseiten des Wälzlagers den Zwischenraum abdichtende ringförmige Dichtungen vorgesehen sein können. Desweiteren kann die vorgeschlagene als ringförmige Dichtung oder als Deckel ausgebildete Dichtung an dem drehenden Lagerring oder in bevorzugter Weise am stehenden Lagerring angeordnet sein.As an alternative to an annular seal, when the rolling bearing is received by a final shaft or axle, the seal can form a cover which completely seals off the rolling bearing at one end, so that the complete inner ring is completely covered at one end face of the rolling bearing, as in the case of wheel bearings, for example , On the opposite side, a correspondingly annular seal may be provided. It is understood that the interspace sealing annular seals can be provided on continuous shafts or axles on both end sides of the rolling bearing. Furthermore, the proposed designed as an annular seal or as a lid seal can be arranged on the rotating bearing ring or in a preferred manner on the stationary bearing ring.
