Die Neuerung betrifft ein wälzlager, vorzugsweise ein großes Zylinderrollenlager, bei dem der Käfig von einzelnen kastenförmigen Segmenten gebildet wird.The innovation concerns a rolling bearing, preferably one Large cylindrical roller bearing in which the cage is made up of individual box-shaped segments.
Aus dem DE-Gm 70 34 212 ist ein Gliederkäfig für zylindrische Wälzkörper bekannt, der aus einer Vielzahl νοπ untereinander formgleichen Einzelgliedern besteht, die iiL aufwendiger Weise untereinander mittels Schrauben verbunden sind.From DE-Gm 70 34 212 a link cage for cylindrical Rolling body known, which consists of a large number of νοπ among each other there is identical individual links, the iiL more complex Way are connected to each other by means of screws.
Aus Fig. 3 und 4 der DE-OS 15 75 603 ist ein Zylinderrollenlager bekannt, bei dem die Rollen von je einem kastenförmigen Segment umfaßt sind. Die Segmente sind untereinander nicht verbunden. Nach Entfernen eines Laufrings besteht kein Zusammenhalt mehr für die restlichenLagerteile.From Fig. 3 and 4 of DE-OS 15 75 603 is a cylindrical roller bearing known, in which the roles are each comprised by a box-shaped segment. The segments are one below the other not connected. After removing a race, there is no longer any cohesion for the remaining bearing parts.
Schließlich ist aus dem DE-Gm 74 32 281 noch ein aus einzelnen mit einer Rollentasche versehenen Gliedern zusammengesetzter Käfig für Axialrollenlager bekannt, bei dem kastenartige nach einer Seite offene Segmente vorgesehen sind, wobei die offene Seite nach dem Einlegen der Wälzkörper durch einen Ring verschlossen wird. Auch ein solches Lager bildet keine Baueinheit und benötigt einen zusätzlichen Ring zum Verschließen und Zusammenfassen der Segmente.Finally, from DE-Gm 74 32 281 there is also one from individual Known with a roller pocket members composite cage for thrust roller bearings, in which box-like segments open to one side are provided, the open side after the rolling elements have been inserted is closed by a ring. Such a bearing also does not form a structural unit and requires one additional ring to close and combine the segments.
Es ist deshalb Aufgabe der Neuerung, ein Wälzlager aufzuzeigen, bei dem Wälzkörper, Käfig und mindestens ein Laufring mit einfachen Mitteln und ohne zusätzliche Teile eine leicht montierbare und wieder demontierbare Baueinheit bilden und wobei auch bei größeren Lager durchmessen! der Käfig billig hergestellt werden kann. It is therefore the task of the innovation to show a rolling bearing in which the rolling elements, cage and at least one raceway form an easily assembled and disassembled structural unit with simple means and without additional parts, and also with larger bearings! the cage can be manufactured cheaply.

Die Lösung ist aus Anspruch 1 ersichtlich. Eine vorteilhafte Ausführung enthält Anspruch 2.The solution can be seen from claim 1. An advantageous embodiment contains claim 2.
Heben den günstigen Preis des Käfigs, vor allem, wenn die Segmente aus Kunststoff gespritzt sind, ist die einfache Montage bzw. Demontage der Segmente vorteilhaft. Die Nut im Laufring fällt fertigungsmäßig nicht ins Gewicht, da die Binge sowieso einer Drehbearbeitung unterliegen und die Nut ohne großen Mehraufwand eingestochen wird. Die axial gerichteten Haltenasen werden im Betrieb infolge der Fliehkraft entlastet, so daß der Käfig gute Gleiteigenschaften aufweist. Da die Taschen dem Wälzkörperprofil angepaßt sind, werden die Bollen nach dem elastischen Einschnappen in die Taschen sicher gehalten und die Segmente werden exakt geführt. Raising the low price of the cage, especially when the segments are injection-molded from plastic, the simple assembly and disassembly of the segments is advantageous. The groove in the race is not significant in terms of production, since the binge is anyway subject to a turning process and the groove is pierced with little extra effort. The axially directed retaining lugs are relieved during operation as a result of the centrifugal force, so that the cage has good sliding properties. Since the pockets are adapted to the rolling element profile, the studs are held securely after they have snapped into place elastically in the pockets and the segments are guided precisely.
Die Neuerung ist in den nachfolgenden Figuren näher dargestellt.

Nach Fig. 1 ist der Innenring 1 bordlos ausgeführt. Die Bollen 2 werden von den Borden 3 des Außenrings 4- geführt. Die Segmente 5, die aus Kunststoff gespritzt sind, haben radiale VorSprunge 6, die axial gerichtete Haltenasen 7 aufweisen. Diese Haltenasen 7 hintergreifen die an denAccording to Fig. 1, the inner ring 1 is designed without a rim. the Bollen 2 are guided by the ribs 3 of the outer ring 4-. The segments 5, which are injection-molded from plastic, have radial projection 6, the axially directed retaining lugs 7 exhibit. These retaining lugs 7 engage behind the to
Stirnseiten des Außenringe 4 angebrachten Nuten 8 und verbinden die Hollen 2, den Außenring 4· und die Segmente 5 zu einer Baueinheit, die auch nach abgezogenem Innenring 1 nicht auseinander fällt. Trotzdem kann sie wieder leicht demontiert werden.End faces of the outer rings 4 attached grooves 8 and connect the lobes 2, the outer ring 4 · and the segments 5 close a structural unit that does not fall apart even after the inner ring 1 has been removed. Nevertheless she can easily again be dismantled.
In Fig. 2 sind die Nuten 8 in die Anlaufseite der Borde 3 eingearbeitet, was den Vorteil aufweist, daß die Nuten 8 als Schmiermittelvorratsraum dienen..In FIG. 2, the grooves 8 are in the contact side of the rims 3 incorporated, which has the advantage that the grooves 8 serve as a lubricant reservoir ..
Wie aus Fig. 3 ersichtlich ist, sind die Segmente 5 zur Aufnahme der Bollen mit Haltelappen 10 versehen, bzw. die Kafigtaschen 9 sind dem Profil der Rolle angepaßt, um sif; im Segment 5 zu halten.As can be seen from Fig. 3, the segments 5 are for Receipt of the balls provided with retaining tabs 10, or the cage pockets 9 are adapted to the profile of the role in order to sif; to hold in segment 5.
Fig. 4 zeigt zwei nebeneinander angeordnete Segmente 5 mit Hollen 2, die so einen einfachen und billigen Käfig bilden.Fig. 4 shows two segments 5 arranged next to one another Hollen 2 that make such a simple and cheap cage.
