Abstract

Roller pockets (6) are offset from the centre line (8) alternately to the left and right in the axial direction, the amount of the offset (9) being determined by the axial displacement of the rollers themselves (2). The pockets can also be offset left and right in groups. Additional components include outer (1) and inner rings defining the cage (3) arranged to lie inward from the respective end flanges (4,5). The displacement of the rollers relates to their movement between loaded and relieved zones of the bearing. The group arrangement can be as required, notably two groups offset left followed by one to the right etc.

Description

Anwendungsgebiet der ErfindungField of application of the invention

Die Erfindung betrifft ein Radiallager, bestehend aus einem Außenring, einem Innenring und zwischen diesen in einem Käfig angeordneten, auf zugehörigen Laufbahnen abrollenden Wälzkörpern, wobei die Wälzkörper an Borden des Außen- und/oder Innenrings geführt sind.The invention relates to a radial bearing consisting of an outer ring, a Inner ring and arranged between them in a cage, on associated Rolling rolling bodies, the rolling elements on the edges of the Outer and / or inner ring are guided.

Hintergrund der ErfindungBackground of the Invention

Ein derartiges Radiallager ist aus Fig. 2 der DE 39 12 856 A1 vorbekannt. Dabei sind die Taschen des Käfigs umlaufend in einer Ebene positioniert, so daß sich der Rollenkranz einseitig an dem Außenringbord oder dem Innenringbord anlegen an. Nun kann aber der Fall eintreten, daß beispielsweise durch eine Wellendurchbiegung oder andere Einflüsse die Wälzkörper in der Lastzone in eine bestimmte Richtung gezwungen werden und dabei die Wälzkörper in der entlasteten Zone über den Käfig in dieselbe Richtung wandern müssen. Verläßt der betreffende Wälzkörper die Lastzone, wandert der Käfig wieder in die andere Richtung. Mit anderen Worten, der Wälzkörperkranz läuft einseitig an, löst sich wieder, läuft wieder an und so weiter. Das heißt, es entsteht durch die Schraubwirkung ein pulsierendes umlaufendes Reibmoment. Dieses Reibmo­ ment stellt eine zusätzliche Verlustquelle im Lager dar. Such a radial bearing is previously known from FIG. 2 of DE 39 12 856 A1. The pockets of the cage are positioned circumferentially in one plane, so that the roller ring lies on one side on the outer ring rim or the inner ring rim. Now, however, the case can occur that, for example, due to a shaft deflection or other influences, the rolling elements in the load zone are forced in a certain direction and the rolling elements in the unloaded zone have to migrate in the same direction over the cage. If the rolling element in question leaves the load zone, the cage moves again in the other direction. In other words, the rolling element ring runs on one side, loosens again, starts again and so on. This means that the screwing action creates a pulsating rotating friction torque. This friction torque represents an additional source of loss in the warehouse.

Zusammenfassung der ErfindungSummary of the invention

Der Erfindung liegt daher die Aufgabe zugrunde, einen Rollenkranz für ein bordgeführtes Radiallager so zu entwickeln, daß ein pulsierendes umlaufendes Reibmoment vermieden wird.The invention is therefore based on the object, a roller ring for to develop on-board radial bearing so that a pulsating rotating Frictional torque is avoided.

Diese Aufgabe wird nach dem kennzeichnenden Teil des Hauptanspruches dadurch gelöst, daß die Tasche gegenüber einer Mittellinie des Käfigs abwech­ selnd von Tasche zu Tasche in axialer Richtung nach links bzw. nach rechts versetzt sind. Dadurch wird erreicht, daß die Wälzkörper unabhängig vonein­ ander in die Lastzone einlaufen können und so das Reibmoment gleichmäßig niedrig bleibt, da sich die Wälzkörper nach beiden Seiten hin orientieren können.This task will be done according to the characterizing part of the main claim solved in that the pocket deviates from a center line of the cage alternating from pocket to pocket in the axial direction to the left or to the right are offset. This ensures that the rolling elements are independent of one another others can enter the load zone and thus the frictional torque evenly remains low because the rolling elements are oriented on both sides can.

Nach Anspruch 2 ist vorgesehen, daß die Größe des axialen Versatzes der Taschen durch die Größe der axialen Verschiebung der Wälzkörper zwischen Lastzone und entlasteter Zone bestimmt ist.According to claim 2 it is provided that the size of the axial offset of the Pockets by the size of the axial displacement of the rolling elements between Load zone and unloaded zone is determined.

Nach dem unabhängigen Anspruch 3 ist es auch möglich, daß die axiale Ver­ schiebung der Taschen gegenüber einer Mittellinie des Käfigs nicht abwech­ selnd von Tasche zu Tasche erfolgt, sondern abwechselnd von mehreren Ta­ schen zu mehreren Taschen. So ist es beispielsweise denkbar, daß zwei Ta­ schen nach links und eine nach rechts oder drei Taschen nach links und zwei Taschen nach rechts versetzt sind.According to the independent claim 3, it is also possible that the axial Ver the sliding of the pockets does not deviate from a center line of the cage alternately from bag to bag, but alternately from several days to several pockets. For example, it is conceivable that two Ta to the left and one to the right or three pockets to the left and two Pockets are offset to the right.

Die Erfindung wird an nachstehendem Ausführungsbeispiel näher erläutert.The invention is explained in more detail using the following exemplary embodiment.

Kurze Beschreibung der ZeichnungBrief description of the drawing

Die einzige Figur zeigt eine Draufsicht auf ein erfindungsgemäßes Radiallager, teilsweise geschnitten. The single figure shows a plan view of a radial bearing according to the invention, partially cut.  

Ausführliche Beschreibung der ZeichnungDetailed description of the drawing

Das in der Figur dargestellte Radialwälzlager besteht aus dem Außenring 1, auf dessen nicht näher bezeichneter Innenlaufbahn die Zylinderrollen 2 abwälzen, die in dem Käfig 3 geführt sind. Der Käfig 3 ist in seiner radialen Ausdehnung so gewählt, daß er unterhalb der radial nach innen gerichteten Borde 4, 5 angeordnet ist. Die Zylinderrollen 2 laufen aus diesem Grund mit ihren Stirn­ flächen an der Innenseite der Borde 4, 5 an, d. h. der Wälzkörperkranz ist bordgeführt.The radial roller bearing shown in the figure consists of the outer ring 1 , on the inner race (not specified) of which the cylindrical rollers 2 roll, which are guided in the cage 3 . The radial extent of the cage 3 is selected such that it is arranged below the radially inwardly directed rims 4 , 5 . For this reason, the cylindrical rollers 2 run with their end faces on the inside of the rims 4 , 5 , ie the rolling element ring is carried on board.

Wie aus der einzigen Figur weiter ersichtlich, sind die Halterungen 7 aufweisen­ den Taschen 6 so angeordnet, daß sie gegenüber der Mittellinie 8 abwechselnd von Tasche 6 zu Tasche 6 in axialer Richtung nach links bzw. nach rechts versetzt sind, d. h. der Versatz 9 verläuft einmal links und einmal rechts neben der Mittellinie 8. Durch diesen alternierend angeordneten Versatz 9 wird erreicht, daß die Zylinderrollen 2 beim Einlaufen in die Lastzone sich unab­ hängig von der jeweiligen Stellung des Käfigs 3 einordnen können.As can also be seen from the single figure, the holders 7 have the pockets 6 arranged in such a way that they are offset from the pocket 6 to the pocket 6 alternately in the axial direction to the left or to the right, ie the offset 9 runs once, with respect to the center line 8 left and once to the right of the center line 8 . This alternately arranged offset 9 ensures that the cylindrical rollers 2 when entering the load zone can be arranged independently of the respective position of the cage 3 .
