Description
Die Neuerung betrifft ein Axial-Zylinderrollenlager, das insbesondere für nur Schwenkbewegungen außführende Lagerungen, z,B, für Lenkschenkellagerungen bestimmt ist. Für dieses Anwendungsgebiet wird ein preisgünstiges Lager verlangt, welches nach Außen abgedichtet sein soll und das als Lagereinheit ungerichtet, also wahloe, eingebaut werden kann.The innovation concerns an axial cylindrical roller bearing, that in particular for swiveling movements only, for example, for steering arm bearings is determined. For this area of application, an inexpensive bearing is required, which is to the outside should be sealed and non-directional as a storage unit, so wahloe, can be built in.
Die bekannten Axial-Wälzlager erfüllen diese Bedingungen nicht optimal, sei es, daß sie zu aufwendig bauen oder, daß bei ihrem Einbau auf die seitenrichtige Anwendung geachtet werden muß. Gemäß der Neuer"^g werden die die Rollenlaufbahnen bildenden gehärteten Feders tahl scheiben von Kunststoff ringen getragen, <?u.e an ihrem Außenumfang alt einer Wulst versehen sind, über die sich am Außenumfang des Rollenkäfigs angeformte Lippen haltend und abdichtend legen. Das neuerungsgemäße Lager ist in sich symmetrisch, sowohl die Laufscheiben als auch die Kunststoffringe sind absolut gleich, die.Werkzeugkosten somit gering. Auch der als Fensterkäfig ausgebildete Rollenkäfig mit den angeformten Halte-und Dichvlippen ist aus Kunststoff einteilig herstellbar, so daß das Lager nur aus '.-fenigen einfachen Teilen besteht, die leicht zu montieren sind. Der gegenüber einem normalen Wälzlager erhöhte Gl.itreibungsanteil, durch die Reibung der Dichtlippen ist bei Lenkschenkellagerungen nicht unerwünscht,,da diese Reibung Lenkungsfiattern entgegenwirkt.The known axial roller bearings do not optimally meet these conditions, be it that they are too expensive to build or that care must be taken when installing them that they are used correctly. According to the New "^ g are the roller tracks forming hardened Feder teel slices of plastic rings worn <? Ue on its outer circumference old a bead are provided place reserved and sealed over which integrally formed on the outer periphery of the roller cage lips. The renewal contemporary bearing Symmetrical in itself, both the running disks and the plastic rings are absolutely the same, the tool costs are therefore low. The roller cage designed as a window cage with the molded retaining and sealing lips can be made of plastic in one piece, so that the bearing is only made of consists of simple parts that are easy to assemble. Compared to a normal roller bearing, the increased sliding friction due to the friction of the sealing lips is not undesirable in the case of steering knuckle bearings, as this friction counteracts steering fiddling.
Die Zeichnung zeigt eine Teilweise geschnittene Sei- ., tenansicht des Neuerungsgegenstandes, Der aus einer Anzahl etwa quadratischer Zylinderrollen 1 bestehende Rollensatz ist in einem Kunststoff-Fensterkäfig 2 gefaßt, dessen Außenrand beiderseitig zur einer Lippe erweitert ist. Die beiden aus Federstahlblech spanlos hergestellten, gehärteten Laufscheiben 3 werden von einem Kunststoffring k getragen, die vorzugsweise aus glasfaserverstärktem Polyamid mit hohem Glasfaseranteil hergestellt sind. Die beiden Ringe k sind bohrungsseitig mit einem Zentrierrand k] für die Laufscheiben versehen und weisen am Außenumfang eine etwa dachförmige Wulst 42 auf. Bei der Montage des Lagers werden die Kunststoffringe 4 mit den gegebenenfalls eingeklebte» Laufscheiben 3 in den Käfig eingeschnappt, wobei die Käfiglippen 21 über die Wulste 42 greifen und die Lagerteile dadurch zusammen halten.The drawing shows a partially sectioned side view. The two hardened running disks 3 made without cutting from spring steel sheet are carried by a plastic ring k , which are preferably made of glass fiber reinforced polyamide with a high glass fiber content. The two rings k are provided on the bore side with a centering edge k] for the running disks and have an approximately roof-shaped bead 42 on the outer circumference. When assembling the bearing, the plastic rings 4 with the possibly glued-in washers 3 are snapped into the cage, the cage lips 21 engaging over the beads 42 and thereby holding the bearing parts together.
