Abstract
Description
Vorzugsweise zweireihiges, kompaktes SchrägkugellagerPreferably double row, compact angular contact ball bearing
Die Erfindung bezieht sich auf ein Schrägkugellager nach dem Oberbegriff des ersten Anspruchs.The invention relates to an angular contact ball bearing according to the preamble of the first claim.
Ein Schrägkugellager der obengenannten Art ist z. B. aus der DE-OS 24 44 340 bekannt. Zwischen den Laufringen ist hier oft nur so wenig Raum, daß nur ein dünnwandiger Kammkäfig eingesetzt werden kann. Damit dieser axial fixiert wird, werden hier zumindest die Kugeln einer Reihe von Haltelappen des Käfigs umgriffen. Diese Haltelappen sind aber of so schwach, daß bei den manchmal stoßartig auftretenden Belastungen nicht sichergestellt ist, daß der Käfig im Lager bleibt. Außerdem ist der Endring des Käfigs zumindest im Taschenbereich so dünn, daß es zu Käfigbrüchen kommen kann. Die Betriebssicherheit eines mit einem solchen Käfig ausgerüsteten zweireihigen Schrägkugellagers ist daher in hohem Maße eingeschränkt.An angular contact ball bearing of the type mentioned above is, for. B. from the DE-OS 24 44 340 known. Often there is so little space between the race rings that only a thin-walled comb cage can be used. So that this is axially fixed, at least the balls of a number of retaining tabs of the cage are encompassed here. However, these retaining lobes are often so weak that the ones that sometimes appear jerkily Loads it is not ensured that the cage remains in the camp. Also is the end ring of the cage is so thin, at least in the pocket area, that the cage breaks can come. The operational safety of someone equipped with such a cage double row angular contact ball bearing is therefore very limited.
Es ist daher Aufgabe der Erfindung, ein Schrägkugellager nach dem Oberbegriff des ersten Anspruchs so weiter zu verbessern, daß sich eine betriebssichere Lagerung ergibt, wobei ein axiales Herauswandern und eine Zerstörung des Käfigs vermieden wird.It is therefore an object of the invention to provide an angular contact ball bearing according to the To improve the preamble of the first claim so that an operationally reliable Storage results, with an axial migration and destruction of the cage is avoided.
Die Lösung ist im kennzeichnenden Teil des ersten Anspruchs angegeben. Die Ansprüche 2 bis 4 enthalten spezielle Ausgestaltungen.The solution is given in the characterizing part of the first claim. Claims 2 to 4 contain special designs.
Dadurch, daß axial versetzt neben den Endringen des Käfigs elastische Haltevorsprünge angeordnet sind, ist eine axiale Fixierung der Käfige auch dann möglich, wenn die Laufringe nur geringe Breite besitzen. Da weiterhin in den Taschenbereichen der Ringteile radial herausragende Verstärkungsrippen vorgesehen sind, wird die Stabilität des Käfigs wesentlich erhöht. Durch die wechselseitioe Anordnung dieser Vorsprünge und Rippen ist eine einfache Herstellung des Käfigs durch axial herausziehbare Formteile möglich.The fact that axially offset next to the end rings of the cage elastic Holding projections are arranged, an axial fixation of the cages is also then possible if the races are only small in width. Since still in the pocket areas the ring parts are provided radially protruding reinforcing ribs, the Stability of the cage significantly increased. Through the reciprocal Arrangement of these projections and ribs is a simple manufacture of the cage possible through axially extractable molded parts.
Aus der DE-OS 24 49 194 sind zwar zweireihige Schrägkugellager bekannt, bei denen die Kamrnkäfige radial gerichtete Vorsprünge besitzen, die in Nuten eines Laufringes eingreifen. Hier handelt es sich aber um Wälzlager, bei denen zwischen den Laufringen sowohl in radialer als auch in axialer Richtung relativ viel Raum vorhanden ist, in denen sowohl die umlaufenden Vorsprünge als auch relativ dickwandige Endringe vorgesehen werden können. Diese Ausführung ist daher nicht mit dem hier neu aufgezeigten Lager vergleichbar.From DE-OS 24 49 194 double row angular contact ball bearings are known, in which the Kamrnkäfige have radially directed projections in the grooves of a Engage the race. But here it is about rolling bearings, where between the races relatively much space both in the radial and in the axial direction is present, in which both the circumferential projections and relatively thick-walled End rings can be provided. This version is therefore not the same as here newly identified camp comparable.
Damit das Einbringen der Kammkäfige erleichtert werden kann, sind nach einer bevorzugten Ausführung die elastischen Haltevorsprünge schräg zu den Endringen hin geneigt. Damit wird weiterhin erreicht, daß ein Herausspringen der Käfige aus den Nuten sehr erschwert wird.So that the introduction of the comb cages can be facilitated according to a preferred embodiment, the elastic retaining projections obliquely to the End rings inclined. This is also achieved that a jumping out of the Cages from the grooves is very difficult.
Die Verstärkungsrippen sind dann optimal, wenn sie sich bis nahe an den jeweiligen Laufring erstrecken. Die Steifigkeit des Käfigs wird noch dadurch erhöht, daß die Verstärkungsrippe eine größere Breite besitzen als die Taschen. In diesem Fall müssen allerdings die elastischen Vorsprünge eine geringere Breite erhalten, was aber nicht weiter nachteilig ist, weil ja am Umfang mindestens so viel angeordnet werden können, wie Stege vorhanden sind.The reinforcement ribs are optimal when they are up close extend the respective race. This increases the rigidity of the cage increases that the reinforcing rib have a greater width than the pockets. In this case, however, the elastic projections must have a smaller width received, which is not a further disadvantage, because at least so in terms of scope much can be arranged as there are bars.
Die Erfindung wird anhand von zwei Figuren näher erläutert.The invention is explained in more detail with reference to two figures.
Fig. 1 zeigt einen Teilquerschnitt durch ein zweireihiges Schrägkugellager gemäß der Erfindung.Fig. 1 shows a partial cross section through a double row angular contact ball bearing according to the invention.
Fig. 2 zeigt einen abgewinkelten Ausschnitt auf einen Käfig nach Fig. 10 Gemäß Fig. 1 besteht das zweireihige Schrägkugellager aus dem mit einem Flansch versehenen Außenring 1, dem ebenfalls mit einem Flansch versehenen Innenring 2 und dem Kammkäfig 3, der zwischen den Stegen 4 Taschen 4' besitzt, in denen sich die Kugelreihen 5 und 6 befinden. Damit der Kammkäfig 3 axial nicht aus dem Lager herauswandern kann, besitzt er im Bereich der Stege 4 jeweils einen elastischen Vorsprung 7, der in eine Nut 8 des Außenrings 1 eingeschnappt ist. Mit Hilfe des Endrings 9 werden einerseits die Stege 4 miteinander verbunden, andererseits sind hier in dem Umfangsbereich, in dem keine Vorsprünge 7 vorgesehen sind, Verstärkungsrippen 10 am Endring 9 angebracht. Dadurch wird der im Taschenbereich sich ergebende kleine Querschnitt des Endrings 9 wesentlich verstärkt. Durch die abwechselnde Anbringung der Vorsprünge 7 und der Verstärkungsrippen 10 ist eine einfache Herstellung des Kammkäfigs 3 möglich.FIG. 2 shows an angled section of a cage according to FIG. 10 According to Fig. 1, the double row angular contact ball bearing consists of the provided with a flange outer ring 1, which is also provided with a flange Inner ring 2 and the comb cage 3, which has 4 pockets 4 'between the webs, in where the rows of balls 5 and 6 are located. So that the comb cage 3 does not extend axially can migrate out of the camp, it has an elastic one in each case in the area of the webs 4 Projection 7 which is snapped into a groove 8 in the outer ring 1. With the help of End ring 9 on the one hand the webs 4 are connected to one another, on the other hand here in the circumferential area in which no projections 7 are provided, reinforcing ribs 10 attached to the end ring 9. This makes the small one that arises in the pocket area Cross-section of the end ring 9 significantly reinforced. Due to the alternating attachment the projections 7 and the reinforcing ribs 10 is a simple manufacture of the Comb cage 3 possible.
Er kann nämlich durch zwei axial entfernbare Ringschieber hergestellt werden.Namely, it can be produced by two axially removable ring slides will.
