Description

Kugelkäfig. Die Erfindung betrifft einen Kugelkäfig für Kugellager, bei denen die bekannten Außen-und Innenringe als Laufringe Verwendung finden und ein Haltering zwischen den äußeren und inneren Laufringen angeordnet ist. Bei derartigen bekannten Kugellagern sind einerseits die Außen- und Innenringe so ausgebildet, daß sie die Kugeln in ihrer Lage sichern und deshalb muß entweder der eine oder andere Ring geteilt sein, um das Einsetzen oder Herausnehmen der Kugeln zu ermöglichen. Anderseits sind: bei den bekannten Kugellagern die Halteringe zwischen den äußeren und inneren Laufringen so gestaltet, daß sie mit Ansätzen die Kugeln so weit umgreifen, daß letztere nicht ohne weiteres in achsialer Richtung in den Käfig eingesetzt oder aus demselben herausgenommen werden können.Ball cage. The invention relates to a ball cage for ball bearings, where the known outer and inner rings are used as races and a retaining ring is disposed between the outer and inner races. With such known ball bearings, on the one hand, the outer and inner rings are designed in such a way that that they secure the balls in their position and therefore either one or another ring can be split to allow the balls to be inserted or removed. On the other hand: in the known ball bearings, the retaining rings between the outer ones and inner races designed in such a way that they grip the balls with lugs so that they that the latter is not readily inserted into the cage in the axial direction or can be taken out of the same.

Der Kugelkäfig nach der Erfindung unterscheidet sich von den bekannten dadurch, d'aß der Haltering, der zwsichen dem Außen- und Innenring angeordnet ist, ein ungehindertes Einsetzen und Herausnehmen der Kugeln in achsialer Richtung gestattet und im Zusammenspiel mit seitlich an dem Innenring befestigten Platten, ein Herausfallen der Kugeln unmöglich macht.The ball cage according to the invention differs from the known ones due to the fact that the retaining ring, which is arranged between the outer and inner ring, an unhindered insertion and removal of the balls in the axial direction is allowed and in interaction with plates attached to the side of the inner ring, falling out that makes bullets impossible.

In der Zeichnung veranschaulicht Fig. i einen Schnitt durch ein zweireihiges Kugel-Lager, während Fig. 2 einen Teil dies Käfigs von oben gesehen darstellt.In the drawing, Fig. I illustrates a section through a two-row Ball bearings, while Fig. 2 shows a part of this cage seen from above.

Die Kugeln in der Kugelreihe r wie in der Reihe a werden in einem gewissen Abstand voneinander durch den Haltering 3 gehalten, der mit Aussparungen .4 für die Kugeln versehen ist. Diese Aussparungen sind nur so tief, daß die durch sie gebildeten Ansätze nicht bis zum Halbmesser der Kugeln ragen, so daß die Kugeln in die Laufrinnen 5 des einteiligen Innenrings zo und in die Aussparungen q. ohne Anwendung von Druck hin, eingelegt werden können. Die Kugeln der Reihe r bz-w. a werden ferner durch ringförmige Platten 6 bzw. 7 gehalten, die sich gegen die Außenkanten 8 bzw. 9 des Innenrings 1o anlegen und lösbar an letzterem befestigt sind. Durch: die Platten 6, 7, die über den Halbmesser der Kugeln hinausragen, wird die Stützfläche für die Kugeln größer als deren halbe Sphären, wodurch die Kugeln verhindert werden, aus den Laufrinnen zu fallen, wenn der innere Laufring frei und von der Lagerschale nicht umschlossen ist.The balls in row r as in row a are in a Certain distance from each other held by the retaining ring 3, the with recesses .4 is provided for the balls. These recesses are only so deep that the through they formed approaches do not protrude to the radius of the balls, so that the balls in the grooves 5 of the one-piece inner ring zo and in the recesses q. without Application of pressure to be inserted. The balls in the row r or -w. a are also held by annular plates 6 and 7, which are against the outer edges 8 or 9 of the inner ring 1o apply and are releasably attached to the latter. By: the plates 6, 7, which protrude beyond the radius of the balls, become the support surface for the balls larger than their half spheres, which prevents the balls from falling out of the troughs when the inner race is free and off the bearing shell is not enclosed.

Der Kugelkäfig hat den Vorteil, daß der Haltering nicht aus biegsamem oder federndem Material hergestellt zu werden braucht, sondern aus nur schwer abnutzbarem Metall gemacht oder gegossen werden kann. Ferner ist es nicht nötig, den Haltering so sorgfältig zu bearbeiten, wie es bei den bekannten Kugelkäfigen erforderlich ist, da nur eine kleine Berührungsfläche zwischen dem Haltering und den Kugeln vorgesehen zu werden braucht.The ball cage has the advantage that the retaining ring is not made of flexible material or resilient material needs to be made, but from difficult to wear Metal can be made or cast. Furthermore, it is not necessary to use the retaining ring so carefully to edit, as it is with the well-known ball cages is required because there is only a small contact area between the retaining ring and the balls needs to be provided.

PATENTANSPRUCH: Kugelkäfig für zweireihige Kugellager mit einem Haltering zwischen äußerer. und inneren Laufringen, gekennzeichnet durch die Vereinigung des Halterings (3); der mit nach beiden Seiten ausmündenden, den Kugeln entsprechenden Aussparungen oder Öffnungen (d.) versehen ist,. welche derart geformt sind, daß die Kugeln in achsialer Richtung ungehindert eingeführt und herausgenommen werden können, und einer an jeder Seite des Lagers angeordneten, am Innenring lösbar befestigten ringförmigen Platte (6, 7), die derart geformt ist und derart mit dem Haltering (3) zusammenwirkt, d'aß sie zusammen mit dem Haltering die Kugeln verhindert, aus ihrer Lage in den Aussparungen (q.) herauszufallen. PATENT CLAIM: Ball cage for double row ball bearings with a retaining ring between outer. and inner races characterized by the union of the retaining ring (3); which is provided with recesses or openings (d.) which open out on both sides and correspond to the balls ,. which are shaped in such a way that the balls can be inserted and removed unhindered in the axial direction, and an annular plate (6, 7) which is arranged on each side of the bearing, releasably attached to the inner ring and which is shaped in such a way and with the retaining ring (3 ) cooperates so that, together with the retaining ring, it prevents the balls from falling out of their position in the recesses (q.).
