Description
Käfig für die Wälzkörper von Wälzlagern Die Erfindung bezieht sich auf einen Käfig für die Wälzkörper von Wälzlagern mit Ausnehmungen für die Aufnahme der Wälzkörper, Bekanntlich werden die Wälzkörper, d.h. Kugeln, Rollen, Kegel usw., von Wälzlagern häufig in einem Käfig, der sich zwischen dem inneren und dem äußeren Laufrng des Lagers befindet, gelagert. Dieser Käfig dient insbesondere als Abstandshalter für die Wälzkörper oder auch als Dichtung, um vorhandenes Fett oder Öl in der Laufbahn des Wälzkörpers zu halten. Cage for the rolling elements of rolling bearings The invention relates on a cage for the rolling elements of rolling bearings with recesses for the reception The rolling elements, as is well known, the rolling elements, i.e. balls, rollers, cones, etc., of rolling bearings often in a cage that is located between the inner and outer Run of the bearing is stored. This cage serves in particular as a spacer for the rolling elements or as a seal to remove any grease or oil in the raceway to keep the rolling element.
In Getrieben und ähnlichen Geräteteilen, die einer Schmierung bedürfen, ist es oft schwierig, dafür zu sorgen, daß räumlich ungünstig, d.h. z.B. verdeckt gelegene Teile ausreichend mit Öl versorgt werden. Aufgabe der Erfndung ist es, einen Käfig für Wälzlager zu schaffen, der es ermöglicht, Öl durch den Wälzlager-Käfig hindurchzupumpen, und somit auch dahinterliegende Teile des Getriebes zuverlässig zu schmieren.In gearboxes and similar device parts that require lubrication, it is often difficult to make sure that the space is unfavorable, i.e. e.g. covered parts are adequately supplied with oil. The task of the invention is To create a cage for rolling bearings that allows oil to pass through the rolling bearing cage to pump through, and thus also underlying parts of the transmission to lubricate reliably.
Diese Aufgabe wird bei einem Käfig der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß der Käfig zwischen den Ausnehmungen für die Wälzkörper Durchbrüche besitzt, die etwa in axialer Richtung verlaufen. Vorteilhafte Ausgestaltungen des erfindungsgemäßen Käfigs sind dadurch gekennzeichnet, daß die Durchbrüche schräg zur axialen Richtung gestellt sind und schaufelartig vorgezogene Außenkanten besitzen. Mit Hilfe der Durchbrüche und ihrer besonderen Anordnung ist es in einfacher Weise möglich, Öl in gewünschter Menge und in gewünschter Richtung durch den Wälzlager-Käfig hindurchzupumpen.This object is achieved according to the invention in a cage of the type mentioned at the beginning solved in that the cage has openings between the recesses for the rolling elements possesses, which run approximately in the axial direction. Advantageous embodiments of the The cage according to the invention are characterized in that the openings are inclined are placed to the axial direction and have shovel-like protruding outer edges. With the help of the openings and their special arrangement, it is easy possible, oil in the desired amount and in the desired direction through the roller bearing cage to pump through.
Anhand eines in der Zeichnung dargestellten Ausführungsbeispiels sei die Erfindung erläutert. Figur 1 zeigt die Draufsicht auf einen Wälzlager-Käfig. In Figur 2 ist eine Schnittdarstellung eines Teiles des Wälzlager-Käfigs gezeigt. Der Käfig 1 des Wälzlagers, der getrennt von den übrigen Teilen des kompletten Wälzlagers dargestellt ist, enthält Ausnehmungen 2 in denen die Wälzkörper 3, im vorliegenden Fall Kugeln, gelagert sind. Der Käfig 1 enthält zwischen den Ausnehmungen 2 Durchbrüche 4. Diese Dumhbrüche 4 verlaufen schräg durch den Käfig 1. In Figur 2, in der ein Schnitt durch einen Teil des abgewickelten Wälzlager-Käfigs dargestellt ist, ist der Verlauf der Durchbrüche 4 leicht zu erkennen. Die Durchbrüche sind unter einem Winkel d , der vorzugeweise zwischen 10 und 15° beträgt, in Umfangsrichtung schräg zur axialen Richtung des Lagers gestellt. Pie Schräge der Durchbrüche bestimmt zusammen mit der Drehgeschwindigkeit des Käfigs 1 u.a. die Durchflußgeschwindigkeit des Öls. Um das Öl besser zu erfassen, sind die Außenkanten 5 der Durchbrüche 4 schaufelartig vorgezogen. In den Figuren 1 und 2 ist durch Pfeile angedeutet, in welcher Richtung Öl in Abhängigkeit von der Drehrichtung des Käfigs 1 gefördert wird.Based on an embodiment shown in the drawing the invention explained. Figure 1 shows the plan view of a roller bearing cage. FIG. 2 shows a sectional view of part of the roller bearing cage. The cage 1 of the rolling bearing, which is separate from the other parts of the complete rolling bearing is shown, contains recesses 2 in which the rolling elements 3, in the present Case balls, are stored. The cage 1 contains 2 openings between the recesses 4. These Dumhbrbruch 4 run obliquely through the cage 1. In Figure 2, in the a Section through part of the developed rolling bearing cage is shown the course of the breakthroughs 4 can easily be seen. The breakthroughs are under one Angle d, which is preferably between 10 and 15 °, inclined in the circumferential direction to the axial direction of the bearing. Pie slope of the breakthroughs determined together with the speed of rotation of the cage 1, among other things, the flow rate of the oil. In order to better grasp the oil, the outer edges 5 are the openings 4th pulled forward like a shovel. In Figures 1 and 2 is indicated by arrows, in which direction oil is conveyed depending on the direction of rotation of the cage 1 will.
Die ausgezogenen Pfeile zeigen die Förderrichtung des Öls bei Rechtsumlauf des Käfigs 1. Gestrichelt dargestellt ist die Förderrichtung bei einem Linksumlauf des Käfigs 1.The solid arrows show the direction in which the oil is conveyed in clockwise rotation of the cage 1. The direction of conveyance is shown in dashed lines with a counterclockwise rotation of the cage 1.
Es versteht sich das sich diese Verhältnisse umkehren, wenn die Durchbrüche 4 in entgegengesetzter Richtung angeschrägt sind. Anstelle der schaufelartigen Ausbildung der Außenkanten der Durchbrüche 4 könnte die Käfigwand zwischen zwei Ausnehmungen als solche in der Weise gekröpft sein, daß sich für die AuBenkanten der Durchbrüche 4 eine vorstehende Auflaufkante ergibt.It goes without saying that these relationships reverse when the breakthroughs 4 are beveled in the opposite direction. Instead of the shovel-like training the outer edges of the openings 4 could be the cage wall between two recesses as such be cranked in such a way that the outer edges of the openings 4 results in a protruding run-up edge.
Die Herstellung des erfindungsgemäßen Käfigs wird besonders einfach wenn als Werkstoff für den Käfig ein Kunststoff oder ein Preßstoff gewählt wird.The manufacture of the cage according to the invention is particularly simple if a plastic or a molded material is chosen as the material for the cage.
