Abstract
Die Erfindung betrifft einen Käfig (1) für zylindrische Wälzkörper (13) eines Wälzlagers (12), umfassend zwei den Käfig (1) axial begrenzende Ringborde (2, 3) und mehrere zwischen den Ringborden (2, 3) angeordnete Stege (4), von denen jeweils ein mittlerer Abschnitt (6) radial nach innen abgekröpft ist. Erfindungsgemäß ist das Verhältnis des Durchmessers des Käfigs (1) zur Breite des Käfigs (1) kleiner als 0,7.The invention relates to a cage (1) for cylindrical rolling bodies (13) of a roller bearing (12), comprising two annular rims (2, 3) axially delimiting the cage (1) and a plurality of ridges (4) arranged between the annular rims (2, 3). , of which in each case a central portion (6) is bent radially inwardly. According to the invention, the ratio of the diameter of the cage (1) to the width of the cage (1) is less than 0.7.
Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft einen Käfig für zylindrische Wälzkörper eines Wälzlagers, umfassend zwei den Käfig axial begrenzende Ringborde und mehrere zwischen den Ringborden angeordnete Stege, von denen jeweils ein mittlerer Abschnitt radial nach innen abgekröpft ist.The invention relates to a cage for cylindrical rolling elements of a rolling bearing, comprising two cage walls axially delimiting ring rims and a plurality of webs arranged between the ring rims, of which in each case a central portion is bent radially inwardly.
Hintergrund der ErfindungBackground of the invention
Ein derartiger Wälzkörperkäfig ist aus der
Für bestimmte Anwendungen wäre es wünschenswert, ein breiteres Wälzlager einzusetzen, dessen Außendurchmesser gleich bleibt oder sogar kleiner ist.For certain applications, it would be desirable to use a wider rolling bearing whose outer diameter remains the same or even smaller.
Aufgabe der ErfindungObject of the invention
Der Erfindung liegt daher die Aufgabe zugrunde, einen Käfig anzugeben, der im Vergleich zu einem herkömmlichen Käfig eine größere Breite bei gleichbleibendem oder kleinerem Außendurchmesser aufweist.The invention is therefore based on the object to provide a cage which has a greater width with constant or smaller outer diameter compared to a conventional cage.
Beschreibung der ErfindungDescription of the invention
Zur Lösung dieser Aufgabe ist bei einem Käfig der eingangs genannten Art erfindungsgemäß vorgesehen, dass das Verhältnis des Durchmessers des Käfigs zur Breite des Käfigs kleiner als 0,7 ist.To achieve this object, it is provided according to the invention in a cage of the type mentioned that the ratio of the diameter of the cage to the width of the cage is less than 0.7.
Der erfindungsgemäße Käfig ist ein sogenannter M-Profil-Käfig, dessen Stege jeweils einen mittleren, radial nach innen gekröpften Abschnitt aufweisen. Das erfindungsgemäße Durchmesser-Breiten-Verhältnis von weniger als 0,7 ermöglicht die Herstellung von langgestreckten Käfigen, die den im Betrieb auftretenden hohen Fliehkräften gewachsen sind. Der erfindungsgemäße Käfig ist als einreihiger Käfig ausgebildet, eine derartige einreihige Lagerung erfüllt höhere Anforderungen an die Tragfähigkeit als eine zwei- oder mehrreihige Lagerung.The cage according to the invention is a so-called M-profile cage, whose webs each have a central, radially inwardly bent portion. The diameter-to-width ratio of less than 0.7 according to the invention makes it possible to produce elongate cages which have grown to the high centrifugal forces occurring during operation. The cage according to the invention is designed as a single-row cage, such a single-row storage meets higher demands on the carrying capacity than a two- or multi-row storage.
Bei dem erfindungsgemäßen Käfig wird es bevorzugt, dass er aus einem Bandmaterial durch Umformen hergestellt ist. Auf diese Weise ist eine kostengünstige Herstellung des erfindungsgemäßen Käfigs möglich.In the cage according to the invention it is preferred that it is made of a strip material by forming. In this way, a cost-effective production of the cage according to the invention is possible.
Eine Variante des erfindungsgemäßen Käfigs kann vorsehen, dass er erste Halteflächen zur Halterung der Wälzkörper radial nach innen und an den nicht abgekröpften Abschnitten zweite Halteflächen für die Halterung der Wälzkörper radial nach außen aufweist. Ein derartiger Käfig ist besonders gut dazu geeignet, die hohen während des Betriebs auftretenden Kräfte aufzunehmen.A variant of the cage according to the invention can provide that it has first holding surfaces for holding the rolling elements radially inwardly and at the non-bent portions second holding surfaces for the support of the rolling elements radially outward. Such a cage is particularly well suited to absorb the high forces occurring during operation.
Bei dem erfindungsgemäßen Käfig wird es bevorzugt, dass die zweiten Halteflächen unmittelbar neben den Ringborden angeordnet sind. Das bedeutet, dass zwischen dem Ringbord und den zweiten Halteflächen jeweils lediglich ein kleiner Freiraum bzw. Abstand vorgesehen ist.In the case of the cage according to the invention, it is preferred that the second holding surfaces are arranged directly next to the annular ribs. This means that only a small free space or distance is provided between the ring board and the second holding surfaces.
Daneben betrifft die Erfindung ein Wälzlager, umfassend einen Käfig der beschriebenen Art und in zwischen benachbarten Stegen gebildeten Taschen aufgenommene zylindrische Wälzkörper. Vorzugsweise sind die ersten Halteflächen des Käfigs und die Wälzkörper bei dem erfindungsgemäßen Wälzlager voneinander beabstandet. Dementsprechend sind die ersten Halteflächen, die auch als Innenhalterungen bezeichnet werden, „freigestellt“. Da zwischen den ersten Halteflächen des Käfigs und den Wälzkörpern kein Kontakt besteht, werden keine Kräfte in den Käfig eingeleitet, wodurch eine hohe Lebensdauer gewährleistet ist.In addition, the invention relates to a rolling bearing, comprising a cage of the type described and cylindrical pockets formed in pockets formed between adjacent webs. Preferably, the first retaining surfaces of the cage and the rolling elements in the rolling bearing according to the invention are spaced from each other. Accordingly, the first retaining surfaces, which are also referred to as inner brackets, "free". Since there is no contact between the first holding surfaces of the cage and the rolling elements, no forces are introduced into the cage, whereby a long service life is ensured.
Daneben betrifft die Erfindung eine Planetenradlagerung für ein Planetengetriebe, mit einem Planetenrad, das mittels eines Wälzlagers der beschriebenen Art an einem Planetenbolzen gelagert ist. Die Planetenradlagerung kann beispielsweise Bestandteil eines Planetengetriebes für ein Stufenautomatikgetriebe für ein Kraftfahrzeug sein.In addition, the invention relates to a planetary gear for a planetary gear, with a planetary gear which is mounted by means of a rolling bearing of the type described on a planet shaft. The Planetenradlagerung can for example be part of a planetary gear for a stepped automatic transmission for a motor vehicle.
