Abstract
Description
Die Erfindung bezieht sich auf ein zweireihiges Schrägkugellager gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a two-row Angular contact ball bearings according to the preamble of the claim 1.
Die beschriebene Ausführung ist in der FR 23 08 013 enthalten. Mit den hervorgehobenen Merkmalen ergibt sich hier eine Baueinheit zwischen allen Lagerteilen. Insbesondere werden die geteilten Innenringe durch an den Käfigen angeformten Vorsprüngen, die in die Nuten der Innenringe ragen, zusammengehalten. Bei dem z. B. in Fig. 13 gezeigten Lager ist es aber erforderlich, am einteiligen Außenring auch an den äußeren Stirnsei ten Schultern vorzusehen, die von der möglichen Bela stungsrichtung her gesehen nicht erforderlich sind. Sie sind aber hier nötig, weil sich sonst keine Bau einheit ergibt. Diese zusätzlichen Außenschultern sind aber nicht nur bei der Herstellung nachteilig, sondern erschweren auch die Montage bzw. Demontage des Lagers. Es ist nämlich kein einfaches axiales Einschieben je der Kugelreihe mit dem geteilten Innenring mehr mög lich.The version described is contained in FR 23 08 013. With the highlighted features, there is a structural unit between all bearing parts. In particular, the divided inner rings are held together by projections formed on the cages and projecting into the grooves of the inner rings. In the z. As shown in Fig. 13 camp, it is necessary to provide on the one-piece outer ring also on the outer Stirnsei th shoulders, seen from the possible loading direction direction not necessary. But they are necessary here, because otherwise there is no unit. These additional outer shoulders are not only disadvantageous during manufacture, but also complicate the assembly and disassembly of the bearing. It is namely not a simple axial insertion depending on the row of balls with the divided inner ring any longer possible.
Es ist daher Aufgabe der Erfindung ein zweireihiges Schrägkugellager aufzuzeigen, das diese Nachteile nicht besitzt und bei dem insbesondere auf die Außen schultern des einteiligen Laufrings verzichtet werden kann, ohne daß die Baueinheit verloren geht.It is therefore an object of the invention a double row Angular contact ball bearings demonstrate these disadvantages does not own and in particular on the outside shoulders of the one-piece race are dispensed with can without losing the unit.
Die Lösung dieser Aufgabe wird durch die kennzeichnen den Merkmale des Anspruchs 1 dargestellt. Der Anspruch 2 enthält eine spezielle Ausführung. The solution to this problem is identified by the the features of claim 1 shown. The claim 2 contains a special version.
Dadurch, daß die Vorsprünge aus schräg vom Käfig weg geneigten Ringabschnitten bestehen, die in die Nuten des jeweils anderen geteilten Laufrings eingreifen, ergibt sich offensichtlich auch dann eine Baueinheit, wenn die Außenschultern des einteiligen Laufrings weg gelassen werden. Dieser einteilige Laufring läßt sich dann einfacher und genauer herstellen. Außerdem ist die Lagerung einfacher montier- und demontierbar, dies insbesondere dann, wenn die als Ringabschnitte ausge bildeten Vorsprünge eine gewisse Elastizität besitzen und in die Nuten der gegenüberstehenden Ringe einge schnappt werden können. Diese Ausführung hat noch den Vorteil, daß zwei identische Käfige benutzt werden können, was die Herstellung derselben vereinfacht und verbilligt.The fact that the projections obliquely away from the cage inclined ring sections exist in the grooves of the other split race ring, there is obviously also a structural unit when the outer shoulders of the one-piece race are gone be left. This one-piece race can be then make it easier and more precise. Besides, is storage easier to assemble and disassemble, this especially if the out as ring sections formed projections have a certain elasticity and into the grooves of the opposing rings can be snapped. This version still has the Advantage that two identical cages are used can, which simplifies the manufacture of the same and cheaper.
Damit sich auch dann eine Baueinheit ergibt, wenn die geteilten Ringe noch nicht im einteiligen Laufring eingebaut sind, sind zusätzlich zu den umgriffenen Ku geln noch weitere Vorsprünge an den jeweiligen Käfigen angebracht, die in die Nut des dazugehörigen Laufrings eingreifen.So that there is a structural unit even if the split rings not yet in the one-piece race are installed in addition to the encircled Ku other protrusions on the respective cages attached into the groove of the associated race intervention.
Bei zweireihigen Lagerungen, bei denen häufig die Axialkräfteanteile wechseln, wie es beispielsweise bei Radlagern von Kraftfahrzeugen im Falle von Kurvenfahrten möglich ist, ist es für die Funkti onsfähigkeit des Lagers günstig, wenn sich die beiden Kugelreihen in Umfangsrichtung gegeneinander verdrehen können. Dies wird hier dadurch erreicht, daß die sich kreuzenden Ringabschnitte jeweils in breitere Frei räume der gegenüberliegenden Ringabschnitte hineinra gen. Zwischen den sich kreuzenden Abschnitten ergeben sich dadurch Spalte. Letztere lassen eine Relativbewe gung der beiden Käfige und damit der beiden Kugelrei hen in Umfangsrichtung gegeneinander zu, ohne daß es zu Zwangskräften bzw. zu Zerstörungen der Käfige kommt.In the case of double-row bearings, in which the Axial force components change, as is the case with Wheel bearings of motor vehicles in the case of Cornering is possible, it is for the radio ability of the camp if the two Twist rows of balls against each other in the circumferential direction can. This is achieved here in that the crossing ring sections each in broader free spaces of the opposite ring sections between the intersecting sections thereby column. The latter leave a relative proof the two cages and thus the two balls hen against each other in the circumferential direction without it to force or destruction of the cages is coming.
Die Erfindung wird anhand von zwei Figuren näher er läutert.The invention is illustrated by two figures purifies.
Fig. 1 zeigt einen Teil Längsschnitt durch ein erfin dungsgemäßes Lager. Fig. 1 shows a partial longitudinal section through an inventions inventions bearing.
Fig. 2 zeigt eine radiale Draufsicht auf die beiden Kugelreihen im Ausschnitt. Fig. 2 shows a radial top view of the two rows of balls in the cutout.
Gemäß Fig. 1 besteht das zweireihige Schrägkugellager in O-Anordnung aus einem einteiligen Außenring 1, zwei Kugelreihen 2 mit den dazugehörigen Kammkäfigen 3 und 4, sowie den symmetrischen Innenringen 5. An den Kammkäfigen 3 und 4 sind erst Vorsprünge 6, 6′ ange formt, die in die Nuten 7′, 7 des jeweils anderen Laufrings hineinragen. Im zusammengebauten Zustand er gibt sich mit diesen einfachen Mitteln auch dann eine Baueinheit, wenn die äußeren Borde am einteiligen Au ßenring 1 (s. Bereich 8) weggelassen sind.Referring to FIG. 1, the double row angular contact ball bearing in O-arrangement of a one-piece outer ring 1, two rows of balls 2 with the associated comb cages 3 and 4, as well as the symmetrical inner rings 5. On the comb cages 3 and 4 are only projections 6 , 6 'is formed, which protrude into the grooves 7 ', 7 of the other race. In the assembled state he gives himself a structural unit with these simple means even if the outer rims on the one-piece outer ring 1 (see region 8 ) are omitted.
Da es oft auch erwünscht ist, daß das Lager im halb montierten Zustand eine Baueinheit bildet, werden die Kugeln, wie Fig. 2 zeigt, von Stegabschnitten 9 der Kammkäfige umgriffen und besitzen außerdem noch meh rere am Umfang verteilte weitere Vorsprünge 10, die in die Nuten 7, 7′ des dazugehörigen Innenrings 5 ein greifen. Beide Maßnahmen bewirken eine Baueinheit des jeweiligen Innenrings 5 mit den dazugehörigen Kugel reihen 2 samt Käfig 3 bzw. 4, wenn diese Teile noch nicht im einteiligen Außenring 1 eingebaut sind.Since it is often also desirable that the bearing forms a structural unit in the semi-assembled state, the balls, as shown in FIG. 2, are encompassed by web sections 9 of the comb cages and also have a plurality of further projections 10 distributed around the circumference, which in the Grooves 7 , 7 'of the associated inner ring 5 engage. Both measures bring about a structural unit of the respective inner ring 5 with the associated ball rows 2 together with the cage 3 or 4 if these parts are not yet installed in the one-piece outer ring 1 .
Da es oft erwünscht ist, daß sich die beiden Kugelrei hen 2 gegeneinander verdrehen können, sind, wie Fig. 2 zeigt, die Ringabschnitte 6, 6′ schmäler als die Freiräume 11, die zwischen dem gegenüberliegenden Ringabschnitten 6′, 6 bzw. weiteren Vorsprüngen 10 vorhanden sind. Diese Freiräume 11 ermöglichen dann eine Verdrehung der Kugelreihen 2 in Umfangsrichtung um einen gewissen Winkel und verhindern so eine höhere Reibung zwischen den Kugeln und den Käfigen bzw. eine Beschädigung der Käfige.Since it is often desirable that the two Kugelrei hen 2 can rotate against each other, are, as Fig. 2 shows, the ring sections 6 , 6 'narrower than the free spaces 11 , between the opposite ring sections 6 ', 6 or other projections 10 are available. These free spaces 11 then allow the rows of balls 2 to be rotated in the circumferential direction by a certain angle and thus prevent higher friction between the balls and the cages or damage to the cages.
