Abstract

A radial sealing ring (20) is connected directly to the spring elements (16,17) and slides with at least one sealing lip (18,19) on a radial sealing surface of the inner ring (2). The radial sealing ring is formed in one piece with the spring element. The spring element can be made from elastomer material. The radial sealing ring is pref. mounted on the spring element so that impurities cannot penetrate axially onto the inner or outer tracks nor in any possible interspaces. Where lubricant is in a housing the lubricant cannot escape through the bearing point. USE/ADVANTAGE - The radial sealing ring can be easily integrated in the inside of the bearing for cost-effective prodn. without increasing axial structural length.

Description

Die Erfindung betrifft ein spielfreies Radialwälzlager, vorzugsweise Vierpunkt-Kugellager, mit zwei in einer Außenhülse geführten beidsei­ tig einer Quermittelebene des Wälzlagers angeordneten äußeren Laufrin­ gen, zwischen deren Außenlaufbahnen und Innenlaufbahnen eines konzen­ trischen Innenrings Wälzkörper abrollen, wobei zumindest einer der beiden Laufringe mittels eines an einem Bord der Außenhülse abgestutz­ ten Federelements in axialer Richtung auf die Wälzkörper zu vorge­ spannt ist.The invention relates to a play-free radial roller bearing, preferably Four-point ball bearing, with two both in an outer sleeve tig a transverse center plane of the rolling bearing arranged outer race gene, between the outer raceways and inner raceways of a conc roll inner ring rolling elements, with at least one of the two races supported by one on a board of the outer sleeve th spring element in the axial direction to the rolling elements is tense.

Ein spielfreies Wälzlager der vorgenannten Gattung ist aus der US-A- 4,718,781 bekannt. Dabei sind jeweils zwischen den beiden Borden der Außenhülse und den beiden Laufringen Ringe aus einem elastomeren Material angeordnet, die die beiden Laufringe in axialer Richtung auf die Reihe von Wälzkörpern zu vorspannen. Es sind darüberhinaus aber auch noch spielfreie Wälzlager bekannt, bei denen das Federelement nicht aus einem elastomeren Material, sondern als eine aus Metall hergestellte Feder gebildet wird. Setzt man ein derartiges Wälzlager der im Stand der Technik gezeigten Bauweise derart ein, daß von außen Schmutz in das Lagerinnere gelangen kann oder daß einseitig Schmier­ mittel dem Lagerinneren zugeführt wird, welches aber nicht aus dem Lager austreten darf, so ist zumindest einseitig neben dem spielfreien Wälzlager ein separater Radialdichtring anzuordnen. Durch diese Ver­ wendung eines zusätzlichen radialen Dichtrings wird aber in uner­ wünschter Weise die gesamte axiale Baulänge der auf diese Weise ge­ schaffenen Lager-Dichtungseinheit vergrößert.A play-free roller bearing of the aforementioned type is known from the US-A- 4,718,781 known. There are each between the two shelves Outer sleeve and the two races rings made of an elastomer Material arranged on the two races in the axial direction to preload the row of rolling elements. It is beyond that also known play-free rolling bearings in which the spring element not of an elastomeric material, but of metal manufactured spring is formed. If you put such a rolling bearing the construction shown in the prior art such that from the outside Dirt can get inside the bearing or that one-sided lubrication is fed to the inside of the warehouse, but not from the Camp may exit, so there is at least one side next to the backlash Rolling bearings to arrange a separate radial sealing ring. Through this ver application of an additional radial sealing ring is in un desirable the total axial length of the ge in this way created bearing seal unit enlarged.

Der Erfindung liegt daher die Aufgabe zugrunde, die vorgenannten Nachteile zu vermeiden und somit an einem Radialwälzlager eine radiale Abdichtung gegenüber einem inneren sich relativ zur Außenhülse drehen­ den Bauteil vorzusehen, die kostengünstig herstellbar ist und nicht zu einer Vergrößerung der axialen Baulänge führt.The invention is therefore based on the object, the aforementioned To avoid disadvantages and therefore a radial on a radial roller bearing Seal against an inner turn relative to the outer sleeve to provide the component that is inexpensive to manufacture and not too leads to an increase in the axial length.

Diese Aufgabe wird an einem spielfreien Radialwälzlager der im Oberbe­ griff des Anspruchs 1 angegebenen Gattung nach dem kennzeichnenden Teil des Anspruchs 1 dadurch gelöst, daß mit dem Federelement unmit­ telbar ein Radialdichtring verbunden ist, der mit zumindest einer Dichtlippe auf einer radialen Dichtfläche des Innenrings gleitet. Auf diese Weise kann mit einfachen Mitteln ein Radialdichtring in das Lagerinnere integriert werden. Der Radialdichtring ist vorzugsweise derart am Federelement angeordnet, daß Verunreinigungen weder in Axialrichtung auf die Innen- und Außenlaufbahnen noch in einen evtl. zwischen den beiden Laufringen und der Außenhülse vorhandenen Zwi­ schenraum gelangen können. Darüberhinaus ist bei einer Anordnung dieses spielfreien Wälzlagers in einem Gehäuse, das ein Schmiermittel aufnimmt, gewährleistet, daß dieses Schmiermittel nicht über die Lagerstelle aus dem Gehäuse austreten kann.This task is performed on a play-free radial roller bearing in the Oberbe handle of claim 1 specified genus for the characterizing Part of claim 1 solved in that with the spring element a radial sealing ring is connected to at least one Sealing lip slides on a radial sealing surface of the inner ring. On in this way, a radial sealing ring can be inserted into the Be integrated inside the warehouse. The radial sealing ring is preferred so arranged on the spring element that contamination neither in Axial direction on the inner and outer raceways in a possible Zwi existing between the two races and the outer sleeve can reach the room. In addition, there is an arrangement this backlash-free rolling bearing in a housing that is a lubricant records, ensures that this lubricant does not have the Bearing point can emerge from the housing.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß der Radi­ aldichtring einteilig mit dem Federelement ausgebildet ist. In diesem Fall soll das Federelement aus einem elastomeren Material hergestellt sein, daß aufgrund seiner Eigenschaften auch eine Abdichtfunktion übernehmen kann und folglich in seinem dem Innenring zugewandten Be­ reich zumindest eine Dichtlippe geformt ist. Bei Verwendung eines elastomeren Materials für das Federelement kann aber auch an das elastomere Material eine aus einem anderen Werkstoff hergestellte Dichtlippe angespritzt sein, so daß nach wie vor das Federelement und die Dichtlippe als gemeinsames Bauteil ausgebildet sind. Auf diese Weise läßt sich ein spielfreies Wälzlager mit einer integrierten Dichtung sehr preiswert herstellen.In a further embodiment of the invention it is provided that the radi is formed in one piece with the spring element. In this In this case, the spring element should be made of an elastomeric material be that due to its properties also a sealing function can take over and consequently in its Be facing the inner ring richly shaped at least one sealing lip. When using a elastomeric material for the spring element can also on the elastomeric material made from another material Injection-molded sealing lip, so that the spring element and the sealing lip are designed as a common component. To this Way, a play-free rolling bearing with an integrated Manufacture gasket very inexpensively.

Zur weiteren Erläuterung der Erfindung wird auf die Zeichnung ver­ wiesen, in der ein Ausführungsbeispiel vereinfacht dargestellt ist. To further explain the invention is ver on the drawing pointed, in which an embodiment is shown in simplified form.  

In der einzigen Figur ist ein spielfreies Radialwälzlager 1 im Längs­ schnitt dargestellt, das als Vierpunkt-Kugellager ausgebildet ist. Das spielfreie Wälzlager 1 weist einen Innenring 2 auf, der üblicherweise auf einer nicht näher dargestellten Welle angeordnet wird und der an einer Umfangsnut 3 Innenlaufbahnen 4, 5 bildet. An diesen Innenlauf­ bahnen 4 und 5 wälzt eine Reihe von als Kugeln ausgebildete Wälzkörper 6 ab. Konzentrisch zum Innenring 2 sind Laufringe 7, 8 angeordnet, an denen durch eine spanlose Formgebung Außenlaufbahnen 9, 10 hergestellt sind.In the single figure, a play-free radial roller bearing 1 is shown in longitudinal section, which is designed as a four-point ball bearing. The play-free rolling bearing 1 has an inner ring 2 , which is usually arranged on a shaft (not shown in more detail) and which forms inner raceways 4 , 5 on a circumferential groove 3 . At this inner race 4 and 5 rolls a series of rolling elements 6 formed as balls. Races 7 , 8 are arranged concentrically to the inner ring 2 , on which outer races 9 , 10 are produced by a non-cutting shape.

Jeder dieser Laufringe 7 und 8 hat einen der Formgebung der Wälzkörper 6 angepaßten Abschnitt 11 mit den entsprechenden Außenlaufbahnen 9, 10 und einen, im Querschnitt gesehen, dazu abgewinkelten Führungsab­ schnitt 12. Über den Führungsabschnitt 12 ist jeder der beiden Lauf­ ringe 7, 8 in einer zylindrischen ebenfalls spanlos hergestellten Außenhülse 13 geführt. Die Außenhülse weist Borde 14, 15 auf, zwischen welchen und den jeweils benachbarten Laufringen jeweils ein Feder­ element 16 bzw. 17, das den entsprechenden Laufring 7 bzw. 8 in axia­ ler Richtung auf die Wälzkörper 6 zu vorspannt, angeordnet ist. Die Federelemente 16, 17 sind radial nach innen in Richtung des Innenrings verjüngt ausgebildet und jeweils mit einer Dichtlippe 18 bzw. 19 versehen, so daß sie in diesem Bereich die Funktion eines Radialdicht­ rings 20 haben.Each of these races 7 and 8 has a section 11 adapted to the shape of the rolling elements 6 with the corresponding outer races 9 , 10 and, seen in cross section, angled guide section 12 . About the guide portion 12 each of the two rings 7 , 8 is guided in a cylindrical outer sleeve 13 also made without cutting. The outer sleeve has rims 14 , 15 , between which and the respective adjacent races each have a spring element 16 or 17 , which biases the corresponding race 7 or 8 in axial direction on the rolling elements 6 , is arranged. The spring elements 16 , 17 are tapered radially inwards in the direction of the inner ring and are each provided with a sealing lip 18 or 19 , so that they have the function of a radial sealing ring 20 in this area.

Aus der einzigen Figur geht hervor, daß die einstückig mit den Dicht­ lippen 18, 19 ausgebildeten elastomeren Federelemente 16, 17 eine Doppelfunktion übernehmen, und zwar eine Vorspannung der Laufringe 7, 8 in axialer Richtung und gleichzeitig eine Abdichtung des Inneren des spielfreien Wälzlagers 1 gegenüber seiner Umgebung. Dies gelingt erfindungsgemäß unter Beibehaltung einer äußerst kompakten Bauweise. Ein derartiges spielfreies Wälzlager 1 eignet sich insbesondere zur Verwendung in Federbeinlagern von Kraftfahrzeugen, bei denen im Radka­ sten eine sehr starke Verschmutzung auftritt und demzufolge das Risiko groß ist, daß das Wälzlager 1 durch eindringenden und auch auf die Laufbahnen 4, 5, 9 und 10 gelangenden Schmutz zerstört wird. Dieses Problem wird durch die in das spielfreie Wälzlager integrierten Radi­ aldichtringe vermieden.From the single figure it can be seen that the elastomeric spring elements 16 , 17 formed in one piece with the sealing lips 18 , 19 perform a double function, namely preloading the races 7 , 8 in the axial direction and at the same time sealing the interior of the play-free rolling bearing 1 with respect to one another its surroundings. This is achieved according to the invention while maintaining an extremely compact design. Such a backlash-free rolling bearing 1 is particularly suitable for use in suspension strut bearings of motor vehicles in which a very heavy contamination occurs in the Radka and consequently the risk is high that the rolling bearing 1 by penetrating and also on the raceways 4 , 5 , 9 and 10th dirt is destroyed. This problem is avoided by the radial sealing rings integrated in the play-free rolling bearing.
