Aufgabe der ErfindungObject of the invention
Es ist die Aufgabe der Erfindung, eine bauraumsparende Dichtung für ein Wälzlager, insbesondere für ein zweireihiges Pendelrollenlager, anzugeben. It is the object of the invention to provide a space-saving seal for a roller bearing, in particular for a double-row spherical roller bearing.
Zusammenfassung der ErfindungSummary of the invention
Diese Aufgabe wird erfindungsgemäß gelöst durch ein abgedichtetes Wälzlager, insbesondere durch ein abgedichtetes zweireihiges Pendelrollenlager, umfassend
einen ersten Lagerring,
einen zweiten Lagerring,
eine Abdeckscheibe, die an dem ersten Lagerring befestigt ist und mit dem zweiten Lagerring einen Dichtspalt ausbildet, und
einen Käfig, an dem eine erste Dichtlippe und eine zweite Dichtlippe befestigt ist,
wobei die erste Dichtlippe nahe dem Dichtspalt mit der Abdeckscheibe eine erste Lippendichtung ausbildet, und
wobei die zweite Dichtlippe nahe dem Dichtspalt mit dem zweiten La gerring eine zweite Lippendichtung ausbildet.This object is achieved by a sealed roller bearing, in particular by a sealed double-row spherical roller bearing, comprising
a first bearing ring,
a second bearing ring,
a cover plate which is fixed to the first bearing ring and forms a sealing gap with the second bearing ring, and
a cage to which a first sealing lip and a second sealing lip is attached,
wherein the first sealing lip forms a first lip seal near the sealing gap with the cover, and
wherein the second sealing lip gerring near the sealing gap with the second La forms a second lip seal.
Vorzugsweise ist vorgesehen, dass die beiden Dichtlippen als Abschnitte eines Kunststoff-Formteils ausgebildet sind.It is preferably provided that the two sealing lips are formed as sections of a plastic molding.
Vorzugsweise ist vorgesehen, dass das Kunststoff-Formteil einen Endabschnitt des Käfigs in einer Nut aufnimmt.It is preferably provided that the plastic molded part receives an end portion of the cage in a groove.
Vorzugsweise ist vorgesehen, dass die Dichtlippen, mittels einer Klebelage an dem Käfig befestigt sind, insbesondere, dass das die Dichtlippen ausbildende Kunststoff-Formteil mittels einer Klebelage an dem Käfig befestigt ist.It is preferably provided that the sealing lips, are attached by means of an adhesive layer on the cage, in particular, that the sealing lips forming plastic molding is secured by means of an adhesive layer on the cage.
Weitere Vorteile und Merkmale der Erfindung ergeben sich aus den abhängigen Ansprüchen sowie aus der Beschreibung eines Ausführungsbeispiels. Further advantages and features of the invention will become apparent from the dependent claims and from the description of an embodiment.
Die Erfindung wird im Folgenden unter Bezugnahme auf die anliegende Zeichnung näher beschrieben und erläutert. The invention will be described and explained in more detail below with reference to the accompanying drawings.
