Dichtring für AxialwälzlagerSealing ring for thrust roller bearings
Die Neuerung bezieht sich auf Wälzlagerabdichtungen und insbesoi.dere auf die Ausbildung eines Dichtringes für Axialwälzlager mit einer Laufscheibt, die am Außenumfang einen hechgezogenen Rand aufweist, der den Wälzkörperkäfig und die zweite Laufscheibe mit Spiel umschließt. Dem Dichtring obliegt neben seiner zweckgemäßen Aufgabe noch die zusätzliche Aufgabe, die Lagerteile zusammenzuhalten, so daß das Lager für Transport und Einbau eine bauliche Einheit bildet. Zur Lösung dieser gemeinsamen Aufgabe weist der auf den hochgezogenen Laufscheibenrand aufschiebbare Dichtring ein Paar sjch nach außen erstreckende, zur Anlage an den beiderseitigen Lagerstützflächen ausgebildete Dichtlippen und einen sicn einseitig von der Bohrung aus radial nach innen erstreckenden Flansch auf, der bei montiertem DiCiitring den Luftspalt zwischen dem hochgezogenen Rand der einen Laufscheibe und denn Außenrand der anderen Laufscneibe überdeckt und somit den Spalt abdichtet und gleichzeitig die eingelegte Laufscheibe und damit auch den Käfig mit den Wälzkörpern in der ersten Laufscheibe hält.The innovation relates to roller bearing seals and insbesoi.dere to the formation of a sealing ring for Axial roller bearing with a running disk, which has a drawn edge on the outer circumference, which encloses the rolling element cage and the second running disk with play. The sealing ring is also responsible for its intended task still the additional task of holding the bearing parts together so that the warehouse for transport and installation forms a structural unit. To solve this common task the sealing ring, which can be pushed onto the raised rim of the running disk, faces a couple of times to the outside extending sealing lips designed to rest on the bearing support surfaces on both sides and a flange extending radially inward from the bore on one side, which when the DiCiitring the air gap between the raised edge of one of the running discs and the outer edge of the covers the other running disk and thus seals the gap and, at the same time, the inserted running disk and thus also holds the cage with the rolling elements in the first running disk.
Die Zeichnung veranschaulicht ein Ausführungsbeispiel des Neue/ungsgegenstp.ndes» Sie zeigt einen Teilaxialschnitt durch ein Axial-Nadelrollenlager.The drawing illustrates an embodiment of the new counterpart »It shows a partial axial section by an axial needle roller bearing.
Die beiden Laufscheiben 1 und 2 des dargestellten Lagers bestehen aus gehärtetem Stahlblech, die Laufscheibe 1 ist außen mit einem hochgezogenen Rand 1' versehen, der die ebene Laufscheibe 2 mit Spiel umschließt. Zwischen den beiden Laufscheiben liegt ein die Nadeln 3 auf Abstand haltender Kunststuffkäfig 4. Ein elastischer Dichtring 5, der auf den hochgezogenen Rand 1' aufgeschoben und dort durch Haftreibung oder durch Anwendung geeigneter Haftmittel gegen Verdrehung gesichert ist, greift mit einem sich einseitig von seiner Bohrung aus radial nach innen erstreckenden Flansch 6 über den Luftspalt zwischen den hochgezogenen Rand 1' und den äußeren Rand der Laufscheibe 2, deckt diesen Spalt ab und verhindert das Herausfallen der Laufscheibe 2. The two running disks 1 and 2 of the bearing shown are made of hardened sheet steel, the running disk 1 is provided on the outside with a raised edge 1 'which surrounds the flat running disk 2 with play. Between the two running disks lies a plastic cage 4 that keeps the needles 3 at a distance. An elastic sealing ring 5, which is pushed onto the raised edge 1 'and secured there against rotation by static friction or by using suitable adhesives, engages one side of its bore from flange 6 extending radially inward across the air gap between the raised edge 1 'and the outer edge of the running disk 2, covers this gap and prevents the running disk 2 from falling out.
