Damit die Wälzkörper (3, 11) leicht in die Käfigtaschen eingesetzt, aber nur sehr schwer wieder demontiert werden können, werden die Haltevorsprünge (4, 9, 14, 19) nach dem Einsetzen der Wälzkörper (3, 11) in die Käfigtaschen durch an- bzw. umgeformte Käfigteile (6, 10, 15, 21) unterstützt, die zwischen den Haltevorsprüngen (4, 9, 14, 19) zweier benachbarter Käfigtaschen angeordnet sind.In a rolling bearing cage (1, 8, 12, 17), the rolling elements (3, 11) are arranged in cage pockets and are held in them by molded retaining projections (4, 9, 14, 19), which are formed by recesses (13, 18). Like. Are formed elastically. So that the rolling elements (3, 11) can be easily inserted into the cage pockets, but can only be removed again with great difficulty, the retaining projections (4, 9, 14, 19) are replaced by inserting the rolling elements (3, 11) into the cage pockets - or reshaped cage parts (6, 10, 15, 21) supported, which are arranged between the holding projections (4, 9, 14, 19) of two adjacent cage pockets.

Description

Die Erfindung bezieht sich auf einen Wälzlagerkäfig mit Taschen zur Aufnahme der Wälzkörper, in welchen diese durch angeformte Haltevorsprünge gehalten werden, wobei die Haltevorsprünge durch Ausnehmungen oder dgl. elastisch ausgeführt sind.The invention relates to a rolling bearing cage with pockets for receiving the rolling elements, in which they are held by molded holding projections, the holding projections being made elastic by recesses or the like.

Es sind bereits Wälzlagerkäfige gemäß dem Oberbegriff des Patentanspruchs 1 bekannt (deutsches Gebrauchsmuster Nr. 1 910 797), die ohne großen Kraftaufwand auf die Kugeln aufgeschnappt werden können. Diese bekannten Käfige springen aber bei ungünstigen Belastungen leicht aus dem Lager heraus, so daß das Lager zerstört werden kann.There are already roller bearing cages known according to the preamble of claim 1 (German utility model No. 1 910 797), which can be snapped onto the balls without great effort. However, these known cages easily jump out of the bearing under unfavorable loads, so that the bearing can be destroyed.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, einen Wälzlagerkäfig der vorstehend beschriebenen Art zu schaffen, bei dem die Wälzkörper leicht in die Käfigtaschen eingesetzt, aber nur sehr schwer wieder demontiert werden können.The invention seeks to remedy this. The invention, as characterized in the claims, solves the problem of creating a rolling bearing cage of the type described above, in which the rolling elements are easily inserted into the cage pockets, but are very difficult to dismantle again.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, daß der Käfig nach dem Einsetzen der Wälzkörper in die Käfigtaschen auch bei ungünstigen Belastungen nicht aus dem Lager herausspringen kann, so daß die Betriebssicherheit gewährleistet ist.The advantages achieved by the invention are essentially to be seen in the fact that the cage after the rolling elements have been inserted into the cage pockets cannot jump out of the bearing even under unfavorable loads, so that operational safety is ensured.

Bevorzugte Ausführungsbeispiele der Erfindung werden nachstehend in Verbindung mit der Zeichnung näher erläutert.Preferred exemplary embodiments of the invention are explained in more detail below in conjunction with the drawing.

Gleiche Teile sind in der Zeichnung mit gleichen Bezugszahlen versehen.The same parts are provided with the same reference numbers in the drawing.

Der in der Fig. 1 dargestellte Schnappkäfig 1 ist aus Kunststoff gefertigt und besitzt hohlkugelig ausgebildete Taschen 2 zur Aufnahme der Kugeln 3, die an den offenen Enden mit Haltevorsprüngen 4 versehen sind. Die Haltevorsprünge 4 sind elastisch ausgeführt, so daß der Käfig 1 ohne Schwierigkeiten auf die Kugeln 3 aufgeschnappt werden kann. Damit der Käfig 1 auch bei ungünstigen Belastungen nicht aus dem Lager springt, sind jeweils zwischen den Haltevorsprüngen 4 zweier benachbarter Käfigtaschen 2 angeformte Zapfen 5 vorgesehen, die nach dem Aufschnappen des Käfigs 1 auf die Kugeln 3 mit einem angestauchten Kopfteil 6 versehen werden, der sich mit dem Rand 7 außen an die Haltevorsprünge 4 anlegt. Hierdurch werden die Haltevorsprünge 4 in ihrer Lage fixiert und ein Herausfallen des Käfigs 1 aus dem Lager sicher vermieden. Es ist zweckmäßig, das Kopfteil 6 nicht bis zur Anlage an die Haltevorsprünge 4 zu verformen, damit die Kugeln 3 beim Anstauchen des Kopfteils 6 nicht in den Käfigtaschen 2 festgeklemmt werden können.The snap cage 1 shown in Fig. 1 is made of plastic and has hollow spherical pockets 2 for receiving the balls 3, which are provided with retaining projections 4 at the open ends. The holding projections 4 are designed to be elastic, so that the cage 1 can be snapped onto the balls 3 without difficulty. So that the cage 1 does not jump out of the bearing even under unfavorable loads, pegs 5 are provided between the holding projections 4 of two adjacent cage pockets 2 and are provided with an upset head part 6 after snapping the cage 1 onto the balls 3 with the edge 7 on the outside against the holding projections 4. As a result, the holding projections 4 are fixed in their position and the cage 1 falls out of the Bearings safely avoided. It is expedient not to deform the head part 6 until it rests on the holding projections 4 so that the balls 3 cannot be clamped in the cage pockets 2 when the head part 6 is compressed.

Bei dem in der Fig. 2 dargestellten Käfig 8 für ein Radial-Zylinderrollenlager sind neben jedem Haltevorsprung 9 angeformte, radial nach außen ragende Ansätze 10 vorgesehen, die nach dem Einsetzen der Zylinderrollen 11 in die Käfigtaschen durch Ultraschall verformt werden, so daß sie mit ihren freien Enden bis nahe an die Haltevorsprünge 9 heranreichen bzw. außen an den Haltevorsprüngen 9 anliegen und diese unterstützen.In the cage 8 shown in FIG. 2 for a radial cylindrical roller bearing, molded, radially outwardly projecting lugs 10 are provided next to each holding projection 9, which are deformed by ultrasound after the insertion of the cylindrical rollers 11 into the cage pockets, so that they are with their Free ends up to close to the holding projections 9 or rest on the outside of the holding projections 9 and support them.

Beim Ausführungsbeispiel nach den Figuren 3 und 4 ist der Schnappkäfig 12, ausgehend von den Stirnflächen an den Stegenden, mit axial verlaufenden Schlitzen 13 versehen, die die Haltevorsprünge 14 voneinander trennen. Nach dem Aufschnappen des Käfigs 12 auf die Kugeln 3 werden aus den Stegenden Vorsprünge 15 herausgeformt und so gebogen, daß zwischen ihren freien Enden ein Spiel verbleibt bzw. sie mit ihren freien Enden aneinanderstoßen und die Haltevorsprünge 14 abstützen. Damit der Käfig 12 elastischer wird, ist es ferner vorteilhaft, ausgehend vom Käfigrücken Ausnehmungen 16 vorzusehen, die ebenfalls nach dem Einbau des Käfigs 12 durch geeignete Maßnahmen wieder verschlossen werden können.In the exemplary embodiment according to FIGS. 3 and 4, the snap cage 12, starting from the end faces at the web ends, is provided with axially extending slots 13 which separate the holding projections 14 from one another. After the cage 12 has been snapped onto the balls 3, projections 15 are formed out of the web projections and bent so that a play remains between their free ends or they abut with their free ends and support the holding projections 14. So that the cage 12 becomes more elastic, it is also advantageous to provide recesses 16 starting from the cage back, which can also be closed again by suitable measures after the installation of the cage 12.

Der Käfig 17 nach der Fig. 5 zeigt eine Ausführungsform, die besonders für Schnappkäfige aus glasfaserverstärktem Kunststoff geeignet ist. Die Käfigstege sind bei dieser Ausführung mit besonders tiefen Einschnitten 18 versehen, so daß die Haltevorsprünge 19 des aus einem verhältnismäßig harten Kunststoffmaterial hergestellten Käfigs beim Aufschnappen auf die Kugeln 3 elastisch ausfedern können. An den Stegenden sind jeweils zwei Vorsprünge 20 angeordnet, die, nach dem Einbau des Käfigs 17, durch Ultraschall so weit in die entsprechenden Einschnitte 18 verformt werden, bis sich zwischen ihren Enden nur noch ein geringes Spiel befindet bzw. bis ihre Enden 21 aneinanderliegen. Auf diese Weise werden die Haltevorsprünge 19 an einer Be-wegung in Umfangsrichtung gehindert und der Käfig sicher im Lager gehalten.The cage 17 according to FIG. 5 shows an embodiment which is particularly suitable for snap cages made of glass fiber reinforced plastic is suitable. The cage webs are provided with particularly deep incisions 18 in this embodiment, so that the retaining projections 19 of the cage made of a relatively hard plastic material can spring out when snapped onto the balls 3. At the web ends, two projections 20 are arranged, which, after installation of the cage 17, are deformed by ultrasound into the corresponding incisions 18 until there is only a slight play between their ends or until their ends 21 abut one another. In this way, the retaining projections 19 are prevented from B e-movement in the circumferential direction and securely held, the cage in the bearing.

Diese beschriebenen Ausführungsformen stellen nur Beispiele eines erfindungsgemäßen Wälzlagerkäfigs dar. Anderungen in der Konstruktion der einzelnen Bauteile sind im Rahmen der Erfindung ohne weiteres möglich. So können beispielsweise die in der Fig. 5 dargestellten Einschnitte 18 bei einem elastischeren Käfigwerkstoff auch weniger tief ausgeführt werden. Ferner kann das Spiel zwischen den umgeformten Käfigteilen und den Haltevorsprüngen so groß ausgeführt werden, daß ein Herausschnappen des Käfigs gerade noch verhindert wird.These described embodiments represent only examples of a roller bearing cage according to the invention. Changes in the construction of the individual components are readily possible within the scope of the invention. For example, the incisions 18 shown in FIG. 5 can also be made less deep in the case of a more elastic cage material. Furthermore, the game between the deformed cage parts and the retaining projections can be made so large that snapping out of the cage is just prevented.
