Die Neuerung betrifft einen mehrreihigen Wälzlagerkäfig, bestehend aus Bordringen, die durch Stege miteinander verbunden sind, bei dem der Abstand zwischen benachbarten Wälzkörperreihen größer als die Breite der stirnseitigen Bordringe ist und der aus einem flachen Band rundgerollt ist.The innovation concerns a multi-row rolling bearing cage, consisting from flange rings, which are connected to one another by webs, in which the distance between adjacent rows of rolling elements is larger than the width of the end flange and which is rolled from a flat strip.
Derartige bekannte, z.B, zweireihige Wälzlagerkäfige haben häufig aus Abmessungsgründen einen mittleren Bordring, der erheblich breiter als die stirnseitigen Bordringe ist. Wenn derartige Käfige aus einem flachen Band rundgerollt werden, hat eine solche Ausbildung den Nachteil, daß sich wegen der über die Breite des Bandes recht unterschiedlichen Querschnitt sverteilung Probleme beim Rundrollen ergeben. Für den Rundrollvorgang wäre es wünschenswert, Borde möglichst gleichen Querschnittes, d.h. also möglichst gleicher Breite zu haben.Such known, e.g., double-row roller bearing cages often for reasons of size a middle rim, the is considerably wider than the front flange rings. When such cages are rolled from a flat strip, Such a design has the disadvantage that because of the very different cross-section over the width of the band Distribution problems arise when rolling round. For the rolling process, it would be desirable to resemble shelves as much as possible Cross-section, i.e. the same width as possible to have.
Der Neuerung liegt die Aufgabe zugrunde, die bei derartigen Käfigen gegebenen Probleme beim Rundrollen durch einfache und billige Maßnahmen zu beseitigen.The innovation is based on the task of solving the problems encountered with such cages when rolling round by simple and eliminate cheap measures.
Gemäß der Neuerung wird dies dadurch erreicht, daß in dem zwischen benachbarten Wälzkörperreihen liegenden Bereich Fenster eingestanzt sind, die in Käfigumfangsrichtung annähernd so breit sind wie benachbarte Käfigtaschen und deren axiale Länge so bemessen ist, daß die Breite der zwischen ihnen und den Käfigtaschen verbleibenden Bordringe angenähert der Breite der stirnseitigen Bordringe entspricht.According to the innovation, this is achieved in that in the area lying between adjacent rows of rolling elements Windows are punched, which are approximately as wide in the cage circumferential direction as neighboring cage pockets and their axial length is such that the width of the rim rings remaining between them and the cage pockets approximates corresponds to the width of the front flange rings.
Diese einfache Maßnahme bedingt keine zusätzlichen Kosten, weil die zwischen den Wälzkörperreihen vorgesehenen Fenster gleichzeitig mit dem Stanzen der Käfigtaschen mitgestanzt werden. Mit dem Einstanzen dieser Fenster ergeben sich für üümtliche Bordringe annähernd gleiche Querschnitte, so daß beim liiegevorgang die vorzunehmenden Verformungen an allen Stellen gleich groß sind.This simple measure does not entail any additional costs because the window provided between the rows of rolling elements be punched at the same time as the cage pockets are punched. With the punching of these windows results for ümtliche rim rings approximately the same cross-sections, so that the deformations to be carried out on all during the lying process Digits are the same size.
In den Zeichnungen ist die Neuerung an einem Ausführungsbeispiel dargestellt. Es zeigen:In the drawings, the innovation is shown in an exemplary embodiment. Show it:
Fig. 1 die perspektivische Ansicht eines neuerungsgemäßen zweireihigen Wälzlagerkäfigs und1 shows the perspective view of a two-row roller bearing cage according to the invention and
Fig. 2 das als Ausgangsmaterial dienende Blechband für den Käfig nach Figur 1 in Ansicht.FIG. 2 shows the sheet metal strip serving as the starting material for the cage according to FIG. 1 in a view.
Der in Figur 1 dargestellte Käfig besteht aus den stirnsei tigen Bordriixgen 1, den mittleren Bordringen 2, den die Käfigtaschen 3 begrenzenden Stegen 4 und den die zwischen den Käfigtaschen 3 angeordneten Fenster 5 begrenzenden Stegen 6.The cage shown in Figure 1 consists of the stirnsei term Bordriixgen 1, the middle rim 2, the Cage pockets 3 delimiting webs 4 and the window 5 arranged between the cage pockets 3 delimiting Bars 6.
Der Käfig ist aus einem flachen Band rundgerollt und an den Stoßstellen 7 verschweißt.The cage is rolled from a flat strip and welded at the joints 7.
In Figur 2 ist das Blechband, aus dem der in Figur 1 dargestellte Ks.*' ; hergestellt ist, in Ansicht gezeigt. Diese Figur läßt erkennen, daß im mittleren Bereich die die Fenster 5 bildenden Ausstattungen eine solche Größe besitzen, daß sie in Längsrichtung des Bandes, der späteren Käfigumfangsrichtung, eine Breite besitzen, die wenigstens angenähert der Breite der Käfigtaschen 3 entspricht, während ihre Länge so gewählt ist, daß die mittleren Bordringe 2 eine Breite besitzen, die wenigstens angenähert der Breite der stlrnseitigen Bordringe 1 entspricht.In Figure 2 is the sheet metal strip from which the Ks. * 'Shown in Figure 1; is made, shown in view. These Figure shows that in the central area the fittings forming the windows 5 are of such a size that they have a width in the longitudinal direction of the band, the later circumferential direction of the cage, which is at least approximately corresponds to the width of the cage pockets 3, while their length is chosen so that the middle rim rings 2 have a width which corresponds at least approximately to the width of the front flange rings 1.
Die Bordringe selbst sind in ihren Endbereichen 8 vorzugsweise annähernd trapezförmig ausgebildet. Diese an den Ekken
mit Abschrägungen versehene Ausbildung hat den Vorteil, daß in die dadurch gebildeten Hohlräume beim Verschweißen
des Käfigbandes sich,bildender Schweißaufwurf eintreten
kann, der damit nicht über die Käfigoberfläche hervorsteht.The rim rings themselves are preferably approximately trapezoidal in their end regions 8. This design, which is provided with bevels at the corners, has the advantage that it enters the cavities formed during welding
of the cage tape, forming sweat build-up occur
that does not protrude beyond the surface of the cage.
