Kombinierte Rollen-Kugellager sind bereits in verschiedenen Ausführungsformen bekannt.combined Roller ball bearings are already in various embodiments known.
So
ist beispielsweise in der
Nachteilig dabei ist, dass die im Durchmesser kleineren Lagerkugeln in keiner Rille, sondern auf einer ebenen Fläche abwälzen. Dies hat zur Folge, dass die Lagerkugeln nur axial wirkende Kräfte, aber keine radial angreifenden Kräfte aufnehmen können. Daraus ergibt sich eine geringere Tragzahl der gesamten Lageranordnung. Darüber hinaus kann dieses kombinierte Rollen-Kugellager aufgrund der L-förmigen Bauform seiner Lagerringe Axialkräfte nur in jeweils einer Richtung aufnehmen.adversely It is that the smaller diameter bearing balls in no Groove, but roll on a flat surface. This has the consequence that the bearing balls only axially acting forces, but no radial attacking personnel be able to record. from that results in a lower load rating of the entire bearing assembly. About that In addition, this combined roller ball bearings due to the L-shaped design its bearing rings axial forces record only in one direction.

Nachteilig dabei ist, dass dieses kombinierte Rollen-Kugellager einen Druckwinkel von nahezu 0° aufweist, so dass es in axialer Richtung relativ geringe Kräfte aufnehmen kann. Auch bei diesem gattungsgemäßen Lager, das in erster Linie zur Aufnahme von radialen Kräften ausgelegt ist, werden die Kugeln zur Fixierung des Käfigs verwendet.The disadvantage here is that this combined roller ball bearing has a pressure angle of almost 0 °, so that it can absorb relatively small forces in the axial direction. Also in this generic camp, which is designed primarily for receiving radial forces, the Ku used to fix the cage.
Zusammenfassung der ErfindungSummary of the invention
Ausgehend von den Nachteilen des bekannten Standes der Technik liegt der Erfindung die Aufgabe zugrunde, ein gattungsgemäßes kombiniertes Rollen-Kugellager bereit zu stellen, das optimal an gegebene Lastverhältnisse sowohl in axialer als auch in radialer Richtung einstellbar ist und das darüber hinaus noch einfach handhabbar ist.outgoing from the disadvantages of the known prior art is the invention the task is based, a generic combined roller bearings to provide the best possible given load conditions is adjustable in both the axial and in the radial direction and that about it also easy to handle.
Erfindungsgemäß wird diese Aufgabe nach dem kennzeichnenden Teil von Anspruch 1 in Verbindung mit dessen Oberbegriff dadurch gelöst, dass das Kugellager als ein Vierpunktkugellager ausgebildet ist, so dass die Laufrillen je zwei Berührungspunkte aufweisen.According to the invention this Task according to the characterizing part of claim 1 in conjunction solved with the preamble by the fact that the ball bearing as a four-point ball bearing is formed so that the grooves two points of contact each exhibit.
Vierpunktkugellager haben am Innenring und am Außenring je zwei kreisbogenförmige Laufbahnen, deren Krümmungsmittelpunkte so gegeneinander versetzt sind, dass die Kugeln die Laufringe bei radialer Belastung in vier Punkten berühren. Die Lager sind für wechselnde, rein axiale Belastung oder überwiegende Axiallast geeignet. Dabei berühren die Kugeln den Innen- und Außenring nur an je einem Punkt, wie in einem axial belasteten Schrägkugellager. Die Kugeln, die, wie vorstehend bereits ausgeführt, insbesondere zur Aufnahme von axialen Kräften dienen, sind dabei in den Laufrillen angeordnet, während die Rollen, die zur Aufnahme der radialen Kräfte dienen, auf den verbleibenden Schulterflächen abrollen. Bei der erfindungsgemäßen Lagerkonstruktion wird demnach die radiale Tragkraft in erster Linie von den Rollen und die axiale Tragkraft in erster Linie vom Vierpunktkugellager übernommen. Durch diese Trennung von radialer und axialer Lastaufnahme ist es möglich, durch unterschiedliche Stellung und Anzahl von Rollen und Kugeln das kombinierte Rollen-Kugellager an den jeweiligen Belastungsfall konkret anzupassen.Four-point contact ball bearings have on the inner ring and on the outer ring two circular arc-shaped each Raceways whose centers of curvature are offset from each other so that the balls at the races Touch radial load in four points. The bearings are for changing, purely axial load or predominant Axial load suitable. Touch it the balls the inner and outer ring only at one point, as in an axially loaded angular contact ball bearing. The balls, which, as already stated above, in particular for receiving of axial forces serve, are arranged in the grooves, while the Rollers that serve to absorb the radial forces on the remaining shoulder surfaces roll. In the bearing structure according to the invention Accordingly, the radial load capacity primarily from the rollers and the axial load capacity adopted primarily from the four-point ball bearing. By This separation of radial and axial load bearing, it is possible through different position and number of rollers and balls the combined Concretely adapt roller roller bearings to the respective load case.
Weitere vorteilhafte Ausführungen der Erfindung sind in den Unteransprüchen beschrieben.Further advantageous embodiments The invention are described in the subclaims.
So ist nach Anspruch 2 vorgesehen, dass das Vierpunktkugellager ungeteilte Lagerringe aufweist. Die kompakt ausgebildeten Lagerringe sorgen dafür, dass das kombinierte Rollen-Kugellager nicht in seine Einzelteile beim Transport zerfallen kann. Darüber hinaus wird durch diese Gestaltung auch dem Endverbraucher die Montage eines solchen Lagers vereinfacht, da es als unverlierbare Baueinheit geliefert wird.So is provided according to claim 2, that the four-point ball bearing undivided Has bearing rings. The compactly designed bearing rings ensure that The combined roller ball bearing does not fit into its individual parts Transport can decay. About that In addition, the assembly is also the end user by this design Such a bearing simplifies since it is delivered as a captive unit becomes.
Nach Anspruch 3 ist vorgesehen, dass das Vierpunktkugellager einen Druckwinkel von 35° aufweisen soll. Dieser hohe Druckwinkel sorgt dafür, dass hohe axiale Kräfte in beiden Richtungen aufgenommen werden können.To Claim 3 is provided that the four-point ball bearing a pressure angle of 35 ° should. This high pressure angle ensures that high axial forces in both Directions can be recorded.
Nach einem weiteren Merkmal gemäß Anspruch 4 ist vorgesehen, dass die Rollen und die Kugeln symmetrisch im Käfig angeordnet sind, wobei eine Rolle einer Kugel oder mehrere Rollen mehreren Kugeln in Umfangsrichtung folgen. Die Art der im Käfig angeordneten Rollen und Kugeln wird vom jeweiligen Anwendungsfall bestimmt. Werden hohe radiale und etwas geringere axiale Kräfte aufgenommen, so werden in erster Linie Zylinderrollen vorhanden sein, während im umgekehrten Fall, in erster Linie Kugeln angeordnet sind.To a further feature according to claim 4 it is provided that the rollers and the balls are symmetrical in the Cage arranged are, with one roll of a ball or multiple rolls of multiple balls follow in the circumferential direction. The type of rollers arranged in the cage and Balls are determined by the particular application. Become high radial and slightly lower axial forces are absorbed, so cylindrical rollers are present in the first place, while in the opposite case, primarily balls are arranged.
Schließlich ist nach einem letzten Merkmal der Erfindung gemäß Anspruch 5 vorgesehen, dass dieses kombinierte Rollen-Kugellager zur Lagerung von Wellen im Getriebebau eingesetzt ist. Das ist immer besonders dann der Fall, wenn hohe Belastungen in beiden axialen Richtungen auftreten und wo eine enge axiale Führung und eine geringe Lagerbreite gefordert werden.Finally is provided according to a last feature of the invention according to claim 5 that this Combined roller ball bearings for shaft bearings in gearbox construction is used. This is always especially the case when high Strains occur in both axial directions and where a close axial guidance and a small bearing width are required.
