Description
Zweireihiges Schrägkugellager Die Erfindung betrifft ein zweireihiges Schrägkugellager, bestehend aus einem dünnwandigen, als Laufring dienenden oder zur Aufnahme von Laufringen geeigneten Außenring, der aus zwei zylindrischen Hülsen besteht, die an den einander zugekehrten Enden offen sind und an ihren anderen Enden einen zur Achse hin gerichteten Bord aufweisen, der als Stützfläche für die kugelförmigen Wälzkörper oder den eingelegten Laufring dient, sowie einen die Innenlaufbahnen tragenden Teil und dazwischen abrollenden kugelförmigen Wälzkörpern.Double row angular contact ball bearing The invention relates to a double row Angular contact ball bearings, consisting of a thin-walled, or used as a raceway Outer ring suitable for holding race rings, consisting of two cylindrical sleeves consists, which are open at the ends facing each other and at their other ends have a rim directed towards the axis, which acts as a support surface for the spherical Rolling bodies or the inserted raceway is used, as well as one of the inner raceways load-bearing part and spherical rolling elements rolling between them.
Derartige Wälzlager sind in verschiedenen Ausführungen bekannt geworden und finden insbesondere dort Verwendung, wo neben großen Radialkräften auch Axialkräfte aufgenommen werden müssen.Such rolling bearings are known in various designs and are particularly used where there are not only large radial forces but also axial forces must be included.
Bei einem bekannten Wälzlager wird zur Verbindung der den Außenring bildenden Hülsen vorgeschlagen, die offenen Enden der Hülsen über ein Ringteil zu stecken und dieses mit den Enden der Hülsen zu verschweißen.In a known roller bearing, the outer ring is used to connect forming sleeves proposed to the open ends of the sleeves via a ring part and weld this to the ends of the sleeves.
Für eine solche Ausbildung ist einerseits ein zusätzliches Bauteil erforderlich, andererseits müssen die offenen Enden der Hülsen auf der Innenseite im Durchmesser reduziert werden, um einen axialen Anschlag für das Ringteil zu erhalten Außerdem besteht bei dieser Ausführung die Gefahr, daß der den offenen Enden gegenüberliegende, radlal nach innen gerichtete Bord der Hülsen, gegen-den die Wälzkörper stirnseitig anlaufen, beim Einpressen der Lagereinheit in eine Gehäusebohrung verdrückt wird, so daß die Gefahr besteht, daß die Wälzkörper blockiert werden.For such a training, on the one hand, there is an additional component required, on the other hand, the open ends of the sleeves must be on the inside be reduced in diameter in order to obtain an axial stop for the ring part In addition, with this design there is the risk that the opposite to the open ends, radly inwards directed edge of the sleeves against which the rolling elements start at the front, pressed into a housing bore when the bearing unit is pressed in so that there is a risk that the rolling elements will be blocked.
Der Erfindung liegt die Aufgabe zugrunde, die geschilderten Mängel zu vermeiden und die Montage eines solchen Wälzlagers wesentlich zu erleichtern4 Erfindungsgemäß wird dies dadurch erreicht, daß der Außendurchmesser der einen Hülse gleich groß oder kleiner als der Innendurchmesser der anderen Hülse ist und die beiden Hülsen ineinander gesteckt, spielfrei gegen die kugelförmigen Wälzkörper angestellt und direkt miteinander verbunden sind.The invention is based on the problem of the deficiencies outlined to avoid and to make the assembly of such a rolling bearing much easier 4 According to the invention this is achieved in that the outer diameter of the one sleeve is equal to or smaller than the inner diameter of the other sleeve and the two sleeves inserted into each other, free of play against the spherical rolling elements employed and directly connected to each other.
In weiterer Ausgestaltung der Erfindung wird dazu vorgeschlagen, daß die beiden Hülsen in dem Bereich, in dem sie sich überdecken, durch verlöten, verschwei-Ben, verkleben oder dergleichen miteinander verbunden sind.In a further embodiment of the invention it is proposed that the two sleeves in the area where they overlap by soldering, welding, glue or the like are connected to one another.
Durch diese Maßnahme wird nicht nur ein gesondertes Bauteil für die Verbindung der Hülsen eingespart, sondern es erübrigt sich auch eine Bearbeitung der Hülsenenden. Ein weiterer Vorteil ergibt sich dadurch, daß die vorgeschlagene Ausbildungsform einen Außenring von doppelter Materialstärke ergibt, der größere Radialkräfte aufnehmen kann. Weiterhin ist dafür Sorge getragen. daß die beim Einpressen der Lagereinheit in eine Gehäusebohrung auftretenden Kräfte keinen Einfluß auf die Kugellaufbahnen haben.This measure is not only a separate component for the Connection of the sleeves saved, but there is also no need for machining of the sleeve ends. Another advantage results from the fact that the proposed Form of training results in an outer ring of twice the material thickness, the larger one Can absorb radial forces. Furthermore, care is taken. that the press in the bearing unit in a housing bore has no effect on the forces Have ball tracks.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung mittels eines Längsschnittes durch ein Wasserpumpenlager dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing by means of a longitudinal section through a water pump bearing and is shown below described in more detail.
Das Schrägkugellager besteht aus dem durch die zylindrischen Hülsen 1 und 2 gebildeten Außenring, in dem zwei Reihen kugelförmiger Wälzkörper 3 abrollen, die in Käfigen 4 gehalten sind und einer die inneren Laufrillen 5 tragenden Welle 6. Die Hülsen 1 und 2 sind an den einander zugekehrten Enden 7 und 8 offen und weisen an ihren anderen Enden zur Achse hin gerichtete Borde 9 und 10 auf, die als äußere Laufbahnen für die kugelförmigen Wälzkörper 3 dienen.The angular contact ball bearing consists of the cylindrical sleeves 1 and 2 formed outer ring in which two rows of spherical rolling elements 3 roll, which are held in cages 4 and a shaft carrying the inner raceways 5 6. The sleeves 1 and 2 are open at the mutually facing ends 7 and 8 and point at their other ends to the axis facing shelves 9 and 10, the outer Raceways for the spherical rolling elements 3 are used.
Der Außendurchmesser der Hülse 1 ist gleich groß oder kleiner als der Innendurchmesser der Hülse 2 ausgeführt, dadurch können die Hülsen 1 und 2 über die auf der Welle 6 montierten kugelförmigen Wälzkörper 3 ineinander gesteckt, spielfrei gegen diese angestellt und direkt miteinander verbunden werden. Die Lagereinheit kann, wie das dargestellte Ausführungsbeispiel zeigt, beidseitig mit einer. Dichtung 11 versehen sein.The outer diameter of the sleeve 1 is equal to or smaller than executed the inner diameter of the sleeve 2, thereby the sleeves 1 and 2 can over the spherical rolling elements 3 mounted on the shaft 6 are plugged into one another, free of play employed against them and connected directly to one another. The storage unit can, as the illustrated embodiment shows, on both sides with a. poetry 11 be provided.
Zum Einpressen der Lagereinheit in eine Gehäusebohrung wird ein entsprechendes Montagewerkzeug an der Stirnkante 12 der Hülse 2 angesetzt und dadurch erreicht, daß keine zusätzliche Vorspannung auf die spielfrei eingestellten kugelförmigen Wälzkörper 3 übertragen wird, da die Einpreßkräfte keinen Einfluß auf die äußeren Laufbahnen in den zylindrischen Hülsen 1 und 2 ausüben.To press the bearing unit into a housing bore, a corresponding Assembly tool attached to the front edge 12 of the sleeve 2 and thereby achieved that no additional preload on the spherical set free from play Rolling body 3 is transmitted, since the press-fit forces have no effect on the outer Exercise raceways in cylindrical sleeves 1 and 2.
Die Erfindung ist jedoch nicht auf das dargestellte Ausführungsbeispiel beschränkt. Es ist durchaus möglich, daß die äußeren Laufbahnen von in die Hülsen 1 und 2 eingesetzten Laufringen gebildet werden oder andere von der beschriebenen Ausführung abweichende Änderungen vorgenommen werden können.However, the invention is not limited to the illustrated embodiment limited. It is quite possible that the outer raceways of into the sleeves 1 and 2 inserted races are formed or others of Changes to the design described can be made.
