FAG Kugelfischer Georg Schäfer R-RS-804-wa-st Kommanditgesellschaft auf Aktien 19.12.1984FAG Kugelfischer Georg Schäfer R-RS-804-wa-st Limited partnership on shares December 19, 1984
Die Erfindung bezieht sich auf einen Käfig nach dem Oberbegriff des ersten Anspruchs.The invention relates to a cage according to the preamble of the first claim.
Ein Käfig der angeführten Art ist aus dem DE-Gm 19 13 bereits bekannt. Hierin wird ein Radia 1 -Ri1lenkugellager gezeigt, das zum Zwecke der einseitigen Dichtung einen Käfig mit T-förmigen Querschnitt besitzt. Der Dichtungseffekt wird dadurch erzielt, daß die Schenkel des Querteils in Randaussparungen der beiden Laufringe hineinragen. Probleme gibt es aber bei der Montage solcher Lager. Aus Vereinfachungsgründen soll nämlich im verstärkten Umfang das gesamte Lager mit Innen- und Außenring gleichzeitig montiert werden. Dabei ergeben sich aber Schwierigkeiten, denn die Stirnseiten der Innen- und Außenringe können nur mit großem, zusätzlichen Aufwand so genau gefertigt werden, daß keine Montagekräfte über die Kugeln übertragen werden.A cage of the type mentioned is already known from DE-Gm 19 13. This is a Radia 1 roller bearing shown, which has a cage with a T-shaped cross-section for the purpose of one-sided seal. The sealing effect is achieved in that the legs of the transverse part protrude into the edge recesses of the two races. However, there are problems with the assembly of such bearings. For the sake of simplicity, namely, in the reinforced Circumference, the entire bearing with the inner and outer ring can be mounted at the same time. Succeed in this But difficulties arise, because the end faces of the inner and outer rings can only be fitted with large, additional Effort can be made so precisely that no assembly forces are transmitted via the balls.
Bei den Normallagern ergibt sich daher die große Gefahr, daß Kugelbeschädigungen bei der Montage auftreten, was zu einem baldigen Lagerausfall führen kann.With normal bearings there is therefore a great risk that ball damage will occur during assembly, which can lead to an early bearing failure.
Es ist daher Aufgabe der Erfindung das Lager nach dem Oberbegriff des ersten Anspruchs so weiter zu verbessern, daß eventuelle Ungenauigkeiten an den Stirnseiten der Innen- und Außenringe beim Einpressen der Lager auf die Welle und in das Gehäuse zu keinen Beschädigungen der Kugeln führen und wobei gleichzeitig die Dichtwirkung erhalten bleibt und sich zusätzlich noch ein Schutz der Stirnseiten der Laufringe gegen Korrosion ergibt.It is therefore the object of the invention to further improve the bearing according to the preamble of the first claim, that any inaccuracies on the end faces of the inner and outer rings when pressing the Bearings on the shaft and in the housing do not damage the balls and at the same time the sealing effect is retained and the end faces of the race rings are additionally protected against corrosion results.
Die Lösung dieser Aufgabe ist im kennzeichnenden Teil des Anspruchs 1 dargelegt. Die Ansprüche 2 bis 3 enthalten spezielle Ausgestaltungen.The solution to this problem is set out in the characterizing part of claim 1. Claims 2 to 3 contain special designs.
3 3U7U93 3U7U9
Dadurch, daß der T-förmige Käfig mit seinem Querteil ganz oder teilweise über die Stirnseiten der Laufringe herausragt und mit den Schenkeln je einem Laufring mit relativ großer Fläche gegenübersteht, können sehr große Montagekräfte aufgebracht werden. Diese werden über die Schenkel des Querteils auf beide Laufringe übertragen. Ungenauigkeiten der Stirnseiten der Laufringe werden dadurch eliminiert, daß Käfige aus elastischen Kunststoff verwendet werden.The fact that the T-shaped cage with its transverse part wholly or partially over the end faces of the Races protrudes and the legs each face a race with a relatively large area, very high assembly forces can be applied. These are over the legs of the cross piece on both Transferring races. Inaccuracies in the end faces of the races are eliminated in that Cages made of elastic plastic are used.
Auch bei großen Ungenauigkeiten werden die Kugeln nicht belastet, denn das Spiel zwischen den Schenkeln und den Laufringen ist immer kleiner als das axiale Spiel der Wälzkörper zum Boden der Käfigtaschen. Da die Kugeln in den Taschen Spiel besitzen, wird sich in Betriebsstellung zwischen dem Schenkeln des T-förmigen Käfigs und den Stirnseiten der Laufringe ein kleiner Spalt einstellen. Dadurch entsteht zu beiden Laufringen hin eine oft erwünschte Labyrinthdichtung. Even with great inaccuracies, the balls are not loaded, because the play between the legs and the races is always smaller than the axial play of the rolling elements to the bottom of the cage pockets. Since the balls in the pockets have play, they are in the operating position between the legs set a small gap between the T-shaped cage and the end faces of the races. This creates an often desired labyrinth seal towards both races.
Nach einer bevorzugten Ausführung werden die Montagekräfte über eine Erhebung am Querteil des Käfigs aufgebracht. Dadurch wird der Kräfteverlauf zusätzlich verbessert. Die Schenkel des Querteils können sich nämlich·je nach Belastung unterschiedlich zurückbiegen. According to a preferred embodiment, the assembly forces are applied via an elevation on the transverse part of the cage. This also improves the force distribution. The legs of the transverse part can namely · bend back differently depending on the load.
Der Dichtungseffekt kann noch erhöht werden, wenn sich nach einer weiteren, bevorzugten Ausgestaltung die Schenkel des Querteils bis an die Mantelfläche des Außenrings und die Bohrungsfläche des Innenrings, erstrecken. Zusammen mit dem Gehäuse und der Welle ergeben sich dann noch günstigere, geknickte Labyrinthspalte und ein Schutz der Laufringstirnseiten.The sealing effect can be increased if, according to a further, preferred embodiment, the Legs of the transverse part extend to the outer surface of the outer ring and the bore surface of the inner ring. Together with the housing and the shaft, even cheaper, kinked labyrinth gaps result and protection of the face of the race.
Die Erfindung wird anhand einer Figur näher erläutert. Sie zeigt einen Teilquerschnitt eines Radial-Ri1lenkugellagers mit einem Kammkäfig.The invention is explained in more detail with reference to a figure. It shows a partial cross-section of a radial Ri1lenkballager with a comb cage.
Gemäß Figur 1 besteht das Lager aus dem Innenring 1, dem Außenring 2, dem Kugelsatz 3 und dem T-förmigen Käfig 4. In Betriebsstellung stehen die Schenkeln 51 und 511 des Querteils 5 des Käfigs 4 den Stirnseiten der Laufringe 1 und 2 mit geringem Spiel 6 gegenüber. According to Figure 1, the bearing consists of the inner ring 1, the outer ring 2, the ball set 3 and the T-shaped cage 4. In the operating position, the legs 5 1 and 5 11 of the transverse part 5 of the cage 4 with the end faces of the races 1 and 2 low game compared to 6.
Am Querteil 5 ist außerdem noch eine umlaufende Erhebung 8 vorgesehen. Wird nun auf letztere eine Montagekraft 9( aufgebracht, so wird zunächst das Spiel 6 zur Null, denn das Spiel 7 zwischen den Kugeln 3 und dem Boden 4' der Käfigtaschen ist kleiner als das Spiel 6. Die Kugeln 3 werden daher in keinem Fall von Montagekräften belastet. Letztere werden hingegen wunschgemäß direkt von den Schenkeln 51 und 511 auf die Laufringe 1 und 2 übertragen. Ungenauigkeiten werden durch die Elastizität der Schenkel 51 bzw. 511 ausgeglichen. Dieser Effekt wird noch erhöht, wenn der Käfig 4 aus Kunststoff besteht.A circumferential elevation 8 is also provided on the transverse part 5. If an assembly force 9 ( is now applied to the latter, then the game 6 is initially zero, because the game 7 between the balls 3 and the bottom 4 'of the cage pockets is smaller than the game 6. The balls 3 are therefore in no case of The latter, on the other hand, as required, are transmitted directly from the legs 5 1 and 5 11 to the races 1 and 2. Inaccuracies are compensated for by the elasticity of the legs 5 1 and 5 11. This effect is increased when the cage 4 is off Made of plastic.
