Description

Die Neuerung betrifft ein kombiniertes Kugel-Schrägrollenlager.The innovation concerns a combined ball and angular contact roller bearing.

Kombinierte Kugel-Schrägrollenlager haben den Zweck, sowohl Radialkräfte als auch Kräfte in beiden axialen Richtungen aufzunehmen.Combined ball and angular contact roller bearings have the purpose of both radial forces as well as to absorb forces in both axial directions.

Im deutschen Gebrauchsmuster 1 891 686 ist eine Lagerkombination beschrieben, bei der zur Aufnahme der radialen Belastung und der Axiallast in einer Richtung ein Schrägrollenlager dient, während die Axiallast in der anderen Richtung durch ein Kugellager aufgenommen wird. Dieses Lager hat jedoch nicht genügend Elastizität, um Stöße aufzufangen und von der Gehäusewand fernzuhalten. Schwingungen, die etwa durch eine Unwucht der Welle erzeugt werden, werden infolge der Starrheit des Lagers nahezu ungedämpft an das Gehäuse weitergegeben.In the German utility model 1 891 686 a storage combination is described, in which an angular roller bearing is used to absorb the radial load and the axial load in one direction, while the axial load is in the the other direction is taken up by a ball bearing. However, this bearing does not have enough elasticity to absorb impacts and keep them away from the housing wall. Vibrations caused by an imbalance in the Shaft generated are passed on to the housing almost undamped due to the rigidity of the bearing.

Weiter sind kombinierte Wälzlager bekannt, deren Lagerringe aus Blech hergestellt sind. Aber auch die bekannten Ausführungen sind nicht elastisch genug, um Stoß- oder Schwingungsenergie in Formänderungsarbeit umzuwandeln.Combined roller bearings are also known, the bearing rings of which are made from sheet metal are. But even the known designs are not elastic enough to convert shock or vibration energy into deformation work.

Der Neuerung liegt die Aufgabe zugrunde, ein allseitig belastbares Lager zu schaffen, das geeignet ist, Stöße und Schwingungen zu dämpfen, geringes Gewicht hat sowie einfach und billig herzustellen ist.The innovation is based on the task of a bearing that can withstand loads on all sides to create that is suitable to dampen shocks and vibrations, has low weight and is easy and cheap to manufacture.

Diese Auf£abe wird neuerungsgemäß dadurch gelöst, daß bei einem kombinierten Kugel-Schrägrollenlager der beiden Wälzkörperreihen gemeinsame Laufring einstückig aus Blech gefertigt ist, wobei der zur Lageraehse parallele, an der Gehäusewand oder Welle abzustützende Teil übergeht in einen dazu rechtwinkligen Teil und danach nochmals abknickt in den Laufbahnteil für die beiden Wälzkörperreihen. Der andere Lagerring bestehtAccording to the invention, this task is solved by the fact that in the case of a combined Ball tapered roller bearings of the two rows of rolling elements common race is made in one piece from sheet metal, the part parallel to the bearing axle and to be supported on the housing wall or shaft merging into a right-angled part and then bends again into the raceway part for the two rows of rolling elements. The other bearing ring is made

in an sich bekannter Weise aus zwei getrennten Laufringen, die in geeigneter Weise miteinander verbunden sind, so daß eine komplette Einheit entsteht. Der aus Blech gefertigte Ring wird zweckmäßigerweise so gestaltet, daß der Abschnitt, der die Laufbahn für das Schrägkugellager trägt, nicht an der Gehäusewand oder der Welle anliegt, damit das Kugellager keine Radialkräfte aufnehmen muß. Dieser Ring kann beispielsweise im Fließpreßverfahren geformt sein, was nebenbei noch den Vorteil mit sich bringt, daß durch die Kaltverformung eine Verfestigung eintritt. Auf diese Weise brauchen die Ringe nicht unbedingt gehärtet zu werden. Die damit erreichte Festigkeit ist im allgemeinen für die Verwendungszwecke des Lagers ausreichend, da es in erster Linie dort eingebaut wird, wo nur geringe Belastungen zu erwarten sind.in a manner known per se from two separate races, which in suitable Wise connected to each other, so that a complete unit is created. The ring made of sheet metal is expedient designed so that the portion that carries the raceway for the angular contact ball bearing does not bear against the housing wall or the shaft, so the ball bearing does not have to absorb any radial forces. This ring can for example be formed in the extrusion process, which incidentally also has the advantage that a solidification by the cold deformation entry. In this way, the rings do not necessarily need to be hardened. The strength thus achieved is generally Sufficient for the purposes of the bearing, as it is primarily installed where only low loads are to be expected.

In der Zeichnung sind zwei Ausführungsbeispiele dargestellt. Fig. 1 zeigt ein Lager, dessen Außenring, Fig. 2 ein Lager, dessen Innenring aus Blech hergestellt ist.Two exemplary embodiments are shown in the drawing. Fig. 1 shows a bearing, the outer ring of which, FIG. 2 shows a bearing, the inner ring of which is made from sheet metal.

Das kombinierte Lager gemäß Fig. 1 besteht im wesentlichen aus den beiden durch geeignete Mittel 1 verbundenen Innenringen für das Schrägrollenlager 2 und das Schrägkugellager 3 sowie dem aus Blech geformten Außenring 4, dessen zur Lagerachse paralleler, an der Gehäusewand abzustützender Teil 5 übergeht in einen dazu nach innen gerichteten rechtwinkeligen Teil 6, der danach nochmals abknickt in den Laufbahnteil 7 für die Schrägrollen 8 und am Ende schließlich das Kugellager 9 umfaßt.The combined camp of FIG. 1 consists essentially of the two Inner rings connected by suitable means 1 for the angular roller bearing 2 and the angular contact ball bearing 3 as well as the one formed from sheet metal Outer ring 4, whose parallel to the bearing axis, to be supported on the housing wall Part 5 merges into a right-angled one directed inwards Part 6, which then bends again into the track part 7 for the inclined rollers 8 and finally includes the ball bearing 9 at the end.

Fig. 2 zeigt ein ähnliches kombiniertes Lager, wobei hier jedoch der Innenring 10 in entsprechender Weise aus Blech hergestellt ist.Fig. 2 shows a similar combined bearing, but here the Inner ring 10 is made in a corresponding manner from sheet metal.

Neben diesen Ausführungsbeispielen sind selbstverständlich noch andere möglich, beispielsweise solche, bei denen beide Laufringe aus Blech hergestellt sind. Schließlich ist der aus Blech gefertigte, gemeinsame Laufring nicht auf das dargestellte Lager beschränkt, sondern kann durchaus auch etwa bei einer Zusammenstellung Kegelrollenlager - Rillenkugellager zur Anwendung kommen.In addition to these exemplary embodiments, there are, of course, others possible, for example those in which both races are made of sheet metal. After all, the one made of sheet metal is common The raceway is not limited to the bearing shown, but can also be used for a combination of tapered roller bearings and deep groove ball bearings come into use.
