Description

Gegenstand der Neuerung ist ein Nadellager, bei dem die Nadeln in einer vorzugsweise spanlos geformten, die äußere Laufbahn bildenden Hülse axial und radial nach außen gehalten sindο Um die Nadeln auch nach Innen gegen Herausfallen zu sichern» ist es bekannt, die seitlichen Anlaufborde der Hülse um die Enden der Nadeln herumzuhö'rdeln o Bei dieser Anordnung müssen die Nadelenden konisch gestaltet oder mit einem Zapfen versehen sein. Beides verteuert die Herstellung der Nadeln und außerdem verringert sich die tragende N&dellänge bei gegebener Lagerbreiteo The object of the innovation is a needle bearing in which the needles are held axially and radially outwards in a preferably non-cutting shaped sleeve that forms the outer raceway zuhö'rdeln the ends of the needles o With this arrangement, the needle ends must be conical or provided with a pin. Both of these make the production of the needles more expensive and, in addition, the load-bearing needle length is reduced for a given bearing width or the like

In .vielen Fällen kann man auf eine dauerhafte innere Halterung der Nadeln verzichten, indem es genügt, die Nadeln.bis zur Montage des Lagers, doho, bis zur Einführung der zu lagernden Welle oder dergleichen, mittels eines Hilfsteiles zu halten0 Dieses Hilfsteil soll einerseits sehr billig sein und muß andererseits bei der Montage des Lagers leicht entfernt werden können, auch durch eine engere Bohrung hindurch» Darüberhinaus wird gefordert, daß das Hilfsteil bei der Handhabung des Lagers sicher an seinem Platz verbleibtοIn .vielen cases one can do without a permanent internal support of the needles by it is sufficient that Nadeln.bis for mounting of the bearing, d o h o, hold until the introduction of the shaft to be supported, or the like, by means of an auxiliary part to be 0 This Auxiliary part should be very cheap on the one hand and must also be easy to remove when assembling the bearing, even through a narrower hole. In addition, it is required that the auxiliary part remains securely in place when handling the bearing

Die für den genannten Zweck seither verwendeten Hilfsteile, nämlich Hülsen aus Pappe oder Kunststofffolie, erfüllen die genannten Forderungen nicht optimal. Die Neuerung schlägt deshalb vor, als Hilfeteil einen annähernd die ganze Lagerbohrung ausfüllenden Stopfen aus leichtem, elastischem Material zu verwenden* der mit Vorspannung in die Lagerbohrung einzubringen ist ο Als besonders vorteilhaftes Material ist künstlicher Schaumetoff zu nennen, der gegebenenfalls mit Schmiermittel oder einem Korrosionsschutzmittel getränkt bzw. benetzt sein kannοThe auxiliary parts that have been used for the stated purpose since then, namely sleeves made of cardboard or plastic film, do not optimally meet the stated requirements. The innovation therefore suggests using a plug made of light, elastic material that fills almost the entire bearing bore as an auxiliary part * which is to be introduced into the bearing bore with preload ο A particularly advantageous material is artificial foam, which may be impregnated with lubricant or an anti-corrosion agent or can be wetted

Die Zeichnung veranschaulicht ein Ausführungsbeispiel des Neuerungsgegenstandesö In Figo 1 ist linke das aus der Hülse 1 und den Nadeln 2 bestehende LagerThe drawing illustrates an embodiment of the novelty article ö In Figo 1 is left to the needles 2, consisting of the sleeve 1 and warehouse
