Haschinenteil mit daran angeordneter Innenlaufbahn fürHash part with an inner raceway for
eine Kugellagerunga ball bearing
Die Erfindung betrifft ein Maschinenteil mit daran angeordneter Innenlaufbahn für eine Kugellageruncf.The invention relates to a machine part with arranged thereon Inner raceway for a ball bearing unit.
Bei Kugollagorungen wird häufig das ~u lagernde Kdsch teil selbst als Laufring benutzt, indem die zylindrische Lagerflache des Maschinenteils mit einer die Lauffläche bilde iden Rinne verschon wird. Der Einfachheit und Billigkeit einer solchen Anordnung steht jedoch das Problem gcjonüber, die Lagerflache gegen Korrosionseinflüsse su schlitzen, wo~u sich die Her teilung des gesamten Maschinenteile aus korrosionsbeständigem Material zumeist aus ,.echr.~~.chen und v;irtschaf tlichen Erwägu. jen heraus verbietet. In the case of Kugollagorungen, the ~ u stored Kj part itself used as a running ring by the cylindrical bearing surface of the machine part with a running surface form the gutter is spared. Of simplicity and cheapness such an arrangement, however, has the problem of protecting the bearing surface against the effects of corrosion, see below slit where ~ u are the division of the entire machine parts mostly made of corrosion-resistant material , .echr. ~~ .chen and commercial considerations. that forbids out.
Aufgabe der Erfindung ist es, unter Beibehaltung der Vermeidung eines mit zwei getrennten Laufringen versehenen gesonderten Kugellagers Maschinenteile der eingangs genannten Art so auszubilden, daß sie ohne größeren technischenThe object of the invention is, while maintaining the avoidance of one provided with two separate races separate ball bearing machine parts of the type mentioned in such a way that they can be used without major technical
SKF 7950/19.2.1971SKF 7950 / 02/19/1971
und wirtschaftlichen Aufwand korrosionsbeständig gemacht werden kann. Gemäß der Erfindung w.i rd diese Aufgabe dadurch gelöst, daß die Innenlaufbahn 3 von einem auf eine Zylinderfläche des Maschinenteils aufgeschobenen und in eine oder mehrere Ringnuten 6 an der Zylinderfläche eingerollten Rohrstück 7 gebildet ist.and economic effort made corrosion-resistant can be. According to the invention w.i rd this object is achieved in that the inner raceway 3 from one to one Cylinder surface of the machine part pushed on and in one or more annular grooves 6 is formed on the tubular piece 7 rolled up on the cylinder surface.
Die Erfindung wird nachstehend anhand der Zeichnung näher erläutert, in welcher im Längsschnitt eine Kugellagerung gemäß der Erfindung beispielsweise dargestellt ist.The invention is explained in more detail below with reference to the drawing, in which a ball bearing in longitudinal section is shown according to the invention, for example.
In der Zeichnung ist mit 1 ein als Drehkörper ausgebildetes Maschinenteil, beispielsweise eine Mutter in einer Bremssteuereinheit, dargestellt, auf welche ohne Beeinträchtigung der freien Drehbarkeit eine Axialkraft ausgeübt v/erden soll. Um diese Axialkraft bei freier Drehbarkeit auf das Maschinenteil zu übertragen, ist eine sowohl axial wie radial wirkende Kugellagerung vorgesehen. Diese besteht aus einem mit 2 bezeichneten Innenring und einem Außenring 3, wozwischen Kugeln 4 sowie ein Käfig 5 angeordnet sind.In the drawing, 1 is a machine part designed as a rotating body, for example a nut in a brake control unit, shown, on which an axial force is to be exerted without impairing the free rotatability. To this axial force with free rotation on the machine part to transmit, both axially and radially acting ball bearing is provided. This consists of a 2 designated inner ring and an outer ring 3, between which balls 4 and a cage 5 are arranged.
Bei solchen Anordnungen hat man bisher entweder das Maschinenteil 1 selbst als inneren Laufring verwendet, indem eine Kugellauffläche in die Lagerfläche des Maschinenteils eingearbeitet wird, oder es mußte der getrennte Innenring eines herkömmlichen Kugellagers auf den die zylindrische Lagerfläche tragenden Abschnitt la des Maschinenteils 1 aufgezogen werden. Gemäß der Erfindung wird demgegenüber die Lagerfläche des Maschinenteils 1 mit einer Ringnut 6 versehen, und es wird auf den die Lagerfläche tragenden Abschnitt la ein Rohrstück 7 aufgeschoben und in die Ringnut 6 eingerollt, so daß das Rohrstück 7 in Stellung gehalten und außensei tig zugleich mit einer Lauffläche 8 versehen wird, die ' im Profil der Form der Kugeln 4 entspricht.In such arrangements, either the machine part 1 itself has been used as an inner race by a Ball running surface is incorporated into the bearing surface of the machine part, or it had to have a separate inner ring conventional ball bearings drawn onto the section la of the machine part 1 carrying the cylindrical bearing surface will. According to the invention, on the other hand, the bearing surface of the machine part 1 is provided with an annular groove 6, and a pipe section 7 is pushed onto the section la bearing the bearing surface and rolled into the annular groove 6, so that the pipe section 7 is held in position and outside tig at the same time is provided with a running surface 8, the ' corresponds in profile to the shape of the balls 4.
SKF. 7950/19.2.1971SKF. 7950 / February 19, 1971
Das Rohrstück 7 ist vor dem Einrollen vorzugsweise mit einer flachen ringförmigen Einsenkung (nicht dargestellt) an der Aussenseite gegenüber der Ringnut 6 versehen, wodurch das Einrollen des Materials in die Ringnut erleichtert wird und ein befriedigenderes Ergebnis des Rollvorgangs erzielt wird. Das Einrollen wird dergestalt vorgenommen, daß das Rohrstück 7 gerade den Boden der Nut 6 in deren Mitte erreicht, im übrigen aber etwas Zwischenraum zum Boden der Nut verbleibt (in der Zeichnung nicht dargestellt).The pipe section 7 is preferably with a before rolling flat annular recess (not shown) on the outside opposite the annular groove 6, whereby the Rolling the material into the ring groove is facilitated and a more satisfactory result of the rolling process is achieved. The curling is made such that the pipe section 7 just reaches the bottom of the groove 6 in the middle, in the but some space remains at the bottom of the groove (not shown in the drawing).
Der Aussenring des Lagers kann aus Blech gedrückt oder gestanzt sein, ebenso der Käfig 5·The outer ring of the bearing can be pressed or punched from sheet metal, as can the cage 5
Da die beiden Lagerringe vergleichsweise nur geringen Material- und Herstellungsaufwand erfordern, können sie, ohne zu teuer zu werden, aus korrosionsbeständigem Stahl hergestellt werden. Dies kann bei vielen Kugellagerungen, die einer Korrosion besonders ausgesetzt sind, von entscheidender Bedeutung sein.Since the two bearing rings require comparatively little material and manufacturing costs, they can be used without being too expensive to be made of corrosion-resistant steel. This can be the case with many ball bearings that are particularly susceptible to corrosion exposed to be vital.
