Description

Käfighülse für Axial-Pendelrollenlager Die Erfindung betrifft eine Käfighülse für Axial-Pendelrollenlager.Cage sleeve for spherical roller thrust bearings The invention relates to a Cage sleeve for spherical roller thrust bearings.

Die wesentlichste Aufgabe der Käfighülse eines Axial-Pendelrollenlagers ist, den. Käfig zu führen. Dazu genügt es nicht, die Käfighülse entsprechend den auftretenden Führungskräften zu bemessen, die Führungsflächen müssen, auch so beschaffen sein, daß Verschleiß der aufeinandergleitenden Flächen von Käfig und Hülse möglichst verhindert wird.. Hierzu ist es vor allem erforderlich, dafür zu sorgen, daß stets eine genügend tragfähige Schmierschicht zwischen: diesen Flächen vorhanden ist.The most important task of the cage sleeve of a spherical roller thrust bearing is that. Lead cage. It is not enough to adjust the cage sleeve according to the occurring executives to measure, the guide surfaces must also be designed in such a way be that wear of the sliding surfaces of the cage and sleeve as possible is prevented .. For this it is especially necessary to ensure that always there is a sufficiently stable smear layer between these surfaces.

In dieser Beziehung sind. die bekannten Käfighülsen noch recht verbesserungsbedürftig. Es ist wohl eine Ausführung bekannt, bei der radial angeordnete Schmierbohrungen dem Öl den. Zutritt zu den aufeinandergleitenden Flächen erleichtern, indessen, befriedigt auch diese Käfighülse nicht restlos. Wie die Erfahrung zeigt, tritt immer wieder Verschleiß auf, der nur allzuoft den Ausfall des ganzen Lagers zur Folge hat. Mit der erfindungsgemäßen Käfighülse werden diese Unzuträglichkeiten vermieden.. Nach der Erfindung wird dies dadurch erreicht, daß die den Käfig führende Planfläche der Käfighülse eine die Entstehung einer tragfähigen. Schmierschicht begünstigende Gestalt erhält.In this relationship are. the known cage sleeves are still in need of improvement. A design is well known in which radially arranged lubrication bores the oil the. Facilitate access to the sliding surfaces, while this cage sleeve does not completely satisfy either. As experience shows, always occurs Wear again, which all too often leads to the failure of the entire bearing Has. With the cage sleeve according to the invention, these inconveniences are avoided. According to the invention, this is achieved in that the plane surface leading the cage the cage sleeve one the emergence of a viable. Smear layer favoring Takes shape.

In der Zeichnung ist Abb. 1 ein Teilschnitt durch ein mit der erfindungsgemäßen Käfighülse ausgerüstetes Axial-Pendelrollenlager, Abb. 2 in größerem Maßstab eine Teilansicht der Käfighülse.In the drawing, Fig. 1 is a partial section through a with the invention Axial spherical roller bearing equipped with a cage sleeve, Fig. 2 on a larger scale Partial view of the cage sleeve.

In der Käfighülse 1 sind, verteilt auf den Umfang, mehrere radiale Bohrungen 2 so angebracht, daß sie die Planfläche 3, auf der der Käfig 4 aufliegt, anschneiden. Die Übergänge 5 der Bohrungen 2 in die Planfläche 3 sind lang auslaufend abgeschrägt, so daß sich keilförmige, die Entstehung einer tragfähigen Schmierschicht begünstigende Schmierspalte ergeben. Da eine Schmierschicht nur aufgebaut wird, wenn die Höhe des Schmierspaltes in Richtung der Bewegung abnimmt und die Käfighülse für beide Drehrichtungen. des Axial-Pendelrollenlagers geeignet sein muß, sind die Übergänge 5 in beiden Drehrichtungen lang auslaufend abgeschrägt. `In the cage sleeve 1, distributed over the circumference, several radial Bores 2 attached so that they the plane surface 3 on which the cage 4 rests, cut. The transitions 5 of the bores 2 in the plane surface 3 are tapered long beveled so that it is wedge-shaped, creating a stable smear layer favorable lubrication gaps result. Since a smear layer is only built up when the height of the lubrication gap decreases in the direction of movement and the cage sleeve for both directions of rotation. of the spherical roller thrust bearing must be suitable, are the Transitions 5 tapered long in both directions of rotation. `
