Description

Die Erfindung betrifft «inen zweiteiligen Wälzlagerkäfig aus bildsamem und erhärtendem Werkstoff, wie Kunstharz u. dgl., und besteht in der durch den Anspruch gekennzeichneten und nachstehend näher erläuterten Art der Verbindung der beiden Teile, die für vorteilhafter gehalten wird als die bekannte Verbindung durch Vernieten oder Verkleben oder durch Metallteile, die in die Käfigteile eingegossen oder bei ihrer Herstellung eingepreßt sind.The invention relates to a two-part rolling bearing cage made of a malleable and hardening one Material such as synthetic resin and the like, and consists in that characterized by the claim and the type of connection between the two parts, which is explained in more detail below, for is held more advantageously than the known connection by riveting or gluing or by metal parts that are cast into the cage parts or pressed in during their manufacture are.

Die Erfindung ist durch die Zeichnungen in einem zweckmäßigen Ausführungsbeispiel dargestellt, und zwar für ein zweireihiges Kugellager. Es zeigtThe invention is illustrated by the drawings in an expedient embodiment shown, for a double row ball bearing. It shows

Fig. ι in großem Maßstab einen radialen Querschnitt durch die beiden Kugellagerreihen, Fig. Ι on a large scale a radial cross section through the two rows of ball bearings,

Fig. 2 eine Aufsicht auf eine der Käfighälften mit eingesetzten, verteilten Verbindungsstücken, 2 shows a plan view of one of the cage halves with inserted, distributed connecting pieces,

Fig. 3 'eine entsprechende Seitenansicht, teilweise im Schnitt,3 'shows a corresponding side view, partly in section,

Fig. 4 in großem Maßstab schaubildlich einen Teil eines Käfigelementes,4 shows a part of a cage element on a large scale,

Fig. 5 ebenfalls schaubildlich ein einzelnes (metallisches) Verbindungselement.5 also shows a diagrammatic view of a single (metallic) connecting element.

Die Wälzkörper«, im Beispiel Kugeln, die in üblicher Weise durch innere Laufkränze b und äußere Laufkränze c abgestützt werden, werden durch Käfige geführt, die aus je zwei Ringen. (I1(I1 aus einem urspriinglidh! bildsamen, später erhärtenden Stoff bestehen, wie Kunstharz u. dgl. Diese beiden Hälften, die an den einander zugekehrten Seiten mit kugligen Pfanneme zur Aufnahme der Kugeln versehen sind, werden gemäß der Erfindung dadurch nach Einbringung der Kugeln miteinander verbunden und im gewünschten Abstand gehalten, daß. zwischen den Pfannen e Aussparungen/ angebracht werden, in die zapfenartige Enden .g von Abstandsstücken oder Verbindungsgliedern U eingesetzt werden. Die Abmessungen der Aussparungen/ bzw. g sind so gewählt, daß die Zapfen mit geeignetem Sitz, z. B. Preßsitz, in die Aussparungen einpassen, und insbesondere wähnend sich die Teilet,dt im warmen Zustand befinden. Nach Erkalten und Erhärten der Ringteile' werden die Abstandsglieder dann an den Zapfen vollkommen fest umspannt. -The rolling elements, in the example balls, which are supported in the usual way by inner running rims b and outer running rims c , are guided by cages, each of which consists of two rings. (I 1 (I 1 consist of an originally plastic, later hardening material, such as synthetic resin and the like of the balls are connected to one another and kept at the desired spacing that. Between the sockets e recesses / are made into which peg-like ends .g of spacers or connecting members U are inserted. The dimensions of the recesses / or g are chosen so that the pegs fit with a suitable seat, for example, press fit into the recesses, and in particular imagining the Divide, d t is in the warm state After cooling and hardening of the ring parts', the spacer members are then spans to the pin completely fixed... -

Die Verbindung kann noch dadurch besonders innig gestaltet werden, daß man die zapfenförmigien Eingriffsenden g aufrauht oder mit feinen Vertiefungen, zahnartigen Vorsprüngen u. dgl. versieht, wie dies in der Zeichnung b.eji i bzw. k angedeutet ist.The connection can be made particularly intimate by roughening the peg-shaped engaging ends g or providing them with fine depressions, tooth-like projections and the like, as indicated in the drawing b.eji i and k .

Das Befestigen von Metallteilen, z. B. Muttern, in Kunstharz- o. dgl. Körpern, z. B. Handgriffen, durch Eindrücken dieser Teile in entsprechende Öffnungen des erwärmten Körpers mit dem. Erfolg, daß die Metallteile nach dem Erkalten des Körpers durteh Schrumpfung gehalten werden, ist hierbei als bekannt vorausgesetzt.The fastening of metal parts, e.g. B. nuts, in synthetic resin o. The like. Bodies, z. B. Handles by pressing these parts into the corresponding openings of the heated one Body with the. Success that the metal parts last after the body has cooled down Shrinkage can be maintained is assumed to be known.
