Abstract

In a radial/axial (thrust) rolling bearing, the axial rolling element ring of which rotates on one face of a race disc, in the hole of which the radial rolling element ring rolls, the rolling element rings being accommodated in cages, one of which is connected positively to the race disc to form a subassembly, axial fixing of the radial and axial bearing part relative to one another is achieved by the fact that the cages (4, 11) each have on one of their enveloping surfaces projections (12, 13) which engage positively one over the other and by means of the radial faces of which the cages (4, 11) are fixed axially relative to one another. <IMAGE>

Description

Radial-Axialwälzlager Radial thrust roller bearings

Die Erfindung betrifft ein Radial-Axialwälzlager, bestehend aus einem, in einem Käfig untergebrachten, axial wirkenden Wälzkörperkranz, der stirnseitig auf einer Laufscheibe umläuft, die eine Bohrung aufweist, welche als Laufbahn für einen zweiten, in einem Käfig untergebrachten, radial wirkenden Wälzkörperkranz dient, wobei ein Käfig mit der Laufscheibe formschlüssig zu einer Baueinheit verbunden ist.The invention relates to a radial axial roller bearing, consisting of a, axially acting rolling element ring housed in a cage, the front side revolves on a running disk which has a bore that serves as a raceway for a second, radially acting rolling element ring housed in a cage serves, with a cage positively connected to the running disk to form a structural unit is.

Es sind sowohl Axiallager (DE-AS 12 11 445), als auch Radiallager (DE-AS 10 56 881) bekannt, deren Käfige formschlüssig mit der Laufscheibe bzw. dem Laufring zu einer Baueinheit verbunden sind. Bisher auf einer gemeinsamen Laufscheibe kombinierte Lager dieser Art erfordern zusätzliche Mittel, wie z.B. Anlaufborde, Sicherungsringe oder dgl., zur Sicherung des zweiten Lagerteiles gegen axiales Verschieben. Dies kann oftmals nur an den angrenzenden Maschinenteilen angebracht werden und somit ist außerdem eine Transportsicherung nötig, da das Lager sonst nicht vormontiert werden kann. Der damit verbundene Arbeits- und Zeitaufwand erhöht den Kostenaufwand und vermindert die Wirtschaftlichkeit.There are both axial bearings (DE-AS 12 11 445) and radial bearings (DE-AS 10 56 881) known whose cages form-fit with the running disc or the Running ring are connected to form a structural unit. So far on a common running disc Combined bearings of this type require additional resources, such as stop rims, Circlips or the like. To secure the second bearing part against axial displacement. This can often only be attached to the adjacent machine parts and Thus, a transport lock is also necessary, since otherwise the bearing will not be preassembled can be. The associated expenditure of time and effort increases the cost and reduces profitability.

Die Erfindung hat sich die Aufgabe gestellt, ein Radial-Axialwälzlager zu schaffen, bei dem sich der radiale und der axiale Lagerteil gegenseitig axial fixieren und so- mit eine vormontierbare Baueinheit bilden.The object of the invention is to provide a radial axial roller bearing to create, in which the radial and the axial bearing part are mutually axial fix and so- with form a preassembled unit.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Käfige an je einer ihrer Hüllflächen einander formschlüssig übergreifende Vorsprünge aufweisen, durch deren radiale Flächen die Käfige gegenseitig axial fixiert sind. Somit erhält man eine komplette Baueinheit, welche aus wenigen Teilen besteht und keinerlei zusätzliche Maßnahmen zur gegenseitigen Fixierung bzw. Zentrierung der axialen und radialen Lagerteile beansprucht. Dadurch entfällt z.B. auch eine Transportsicherung. Die Laufscheibe weist eine einfache Form auf, wodurch ein Minimum an Bearbeitung und ein dadurch bedingter geringer Materialverlust erreicht wird.This object is achieved according to the invention in that the cages each have one of their enveloping surfaces positively overlapping projections, the cages are mutually axially fixed by their radial surfaces. Thus receives a complete structural unit, which consists of a few parts and no additional parts Measures for mutual fixation or centering of the axial and radial Storage parts stressed. This means that there is no need for a transport lock, for example. the Washer has a simple shape, which allows a minimum of machining and a resulting low material loss is achieved.

Eine vorteilhafte Ausbildung der Erfindung zeigt einen an der äußeren Käfighüllfläche des radial wirkenden Wälzkörperkranzes annähernd radial nach außen gerichteten Vorsprung, der in eine von der Laufscheibe und dem Käfig des axial wirkenden Wälzkörperkranzes begrenzte Umfangsnut einschnappt.An advantageous embodiment of the invention shows one on the outer Cage envelope surface of the radially acting rolling element ring approximately radially outwards directed projection, which is in one of the running disk and the cage of the axially acting Rolling element rim snaps limited circumferential groove.

Eine andere vorteilhafte Ausbildung der Erfindung schafft dadurch, daß ein an der inneren Käfighüllfläche des axial wirkenden Wälzkörperkranzes annähernd radial zur Lagerachse gerichteter Vorsprung in eine von der Laufscheibe und dem Käfig des radial wirkenden Wälzkörperkranzes begrenzte Umfangsnut eingreift, eine weitere Möglichkeit mit einfachsten Mitteln und einem Minimun an einfach geformten Teilen eine Baueinheit mit geringem Platzbedarf wirtschaftlich herzustellen.Another advantageous embodiment of the invention creates that an approximate to the inner cage envelope surface of the axially acting rolling element ring projection directed radially to the bearing axis in one of the running disk and the Cage of the radially acting rolling element ring engages limited circumferential groove, a Another possibility with the simplest means and a minimum of simply shaped Share a structural unit with a small footprint to produce economically.

In den Zeichnungen sind zwei Ausführungsbeispiele der Erfindung dargestellt, die im folgenden näher beschrieben werden. Es zeigen: Fig. 1 einen Längsschnitt durch ein erfindungsgemäßes Radial-Axialwälzlager, Fig. 2 einen Längsschnitt durch eine Variante des in Fig. 1 dargestellten Lagers.In the drawings, two exemplary embodiments of the invention are shown, which are described in more detail below.

The cage 16 also has a ring-shaped outwardly protruding projection 17, which, however, is on the end face 2 opposite running ring face 18 rests. The cage 15 engages with one on the inner cage envelope surface 19 pointing radially to the bearing axis, annularly formed Projection 20 in a circumferential groove 21, which is formed by the running disk 1 and an annular Projection 22 of the cage 16 is formed.

Der Zusammenbau dieser Lagereinheiten erfolgt durch das Einfügen des in dem Käfig 11 bzw. 16 untergebrachten, radial wirkenden Wälzkörperkranzes 10 in die Bohrung 9 des Laufringes 1 und das anschließende axiale Darüberschieben des Käfigs 4 bzw 15 über die Laufscheibe 1 bzw.These storage units are assembled by inserting the housed in cage 11 or 16, radially acting rolling element ring 10 into the bore 9 of the race 1 and then axially pushing it over it of the cage 4 or 15 over the running disk 1 or
