Abstract
Die Erfindung betrifft eine Lagereinheit (10, 11) mit einem Kugellager (12, 13) das einen Innenring (14) und/oder einen Außenring (15) aufweist, wobei der Innenring (14) und/oder der Außenring (15) zwei axial hintereinander angeordnete Teilinnenringe (100, 101) und/oder Teilaußenringe (16, 17) aufweist. Bisher drückt nur ein Federelement auf einen der beiden Teilaußenringe, weshalb infolge einer Wärmeausdehnung die Kugeln undefiniert zwischen den inneren und den äußeren Lagerringen hin- und herlaufen. Deshalb sind erfindungsgemäß an den äußeren Stirnseiten der Teilinnenringe (100, 101) und/oder der Teilaußenringe (16, 17) Federelemente (103, 104, 106, 107) angeordnet.The invention relates to a bearing unit (10, 11) with a ball bearing (12, 13) which has an inner ring (14) and / or an outer ring (15), the inner ring (14) and / or the outer ring (15) having two axially having partial inner rings (100, 101) and / or partial outer rings (16, 17) arranged one behind the other. So far, only one spring element presses on one of the two partial outer rings, which is why the balls run back and forth between the inner and outer bearing rings in an undefined manner due to thermal expansion. Therefore, according to the invention, spring elements (103, 104, 106, 107) are arranged on the outer end faces of the partial inner rings (100, 101) and / or the partial outer rings (16, 17).
Description
Die Erfindung betrifft eine Lagereinheit mit einem Kugellager, das einen Innenring und/oder einen Außenring aufweist, wobei der Innenring und/oder der Außenring zwei axial hintereinander angeordnete Teilinnenringe und/oder Teilaußenringe aufweist.The invention relates to a bearing unit with a ball bearing having an inner ring and / or an outer ring, wherein the inner ring and / or the outer ring has two axially arranged behind one another part inner rings and / or part outer rings.
Solche gattungsgemäßen Lagereinheiten werden in der
Die Erfindung hat die Aufgabe eine gattungsgemäße Lagereinheit dahingehend zu verbessern, dass zukünftig die oben genannten Nachteile vermieden werden.The invention has the object to improve a generic storage unit to the effect that the above-mentioned disadvantages are avoided in the future.
Die Aufgabe wird erfindungsgemäß mit einer Lagereinheit der eingangs genannten Art gelöst, bei der an den äußeren Stirnseiten der Teilinnenringe und/oder der Teilaußenringe Federelemente angeordnet sind. Somit pressen die Federelemente an beiden äußeren Stirnseiten gegen die Teilinnenringe und/oder die Teilaußenringe. Dadurch können thermisch bedingte Größenänderungen innerhalb der Lagereinheit und bezüglich eines die Lagereinheit umgebenden Gehäuses kein unerwünschtes Lagerspiel mehr erzeugen. Eine Spielfreiheit ist somit gewährleistet.The object is achieved according to the invention with a bearing unit of the type mentioned above, in which spring elements are arranged on the outer end faces of the partial inner rings and / or the outer partial rings. Thus, the spring elements press against the part inner rings and / or the part outer rings on both outer end faces. As a result, thermally induced changes in size within the bearing unit and with respect to a housing surrounding the bearing unit can no longer produce an undesired bearing clearance. A backlash is thus guaranteed.
Das Kugellager kann in einer Hülse angeordnet sein, die wenigstens teilweise über die äußeren Stirnseiten der Teilaußenringe gezogene Ränder aufweist, wobei zwischen den Rändern und den Stirnseiten die Federelemente angeordnet sind. Somit können die Federelemente zuverlässig gegen die Teilinnenringe und/oder die Teilaußenringe drücken. Als Federelemente können sämtliche dem Fachmann bekannte Federn in Betracht kommen, insbesondere Tellerfedern, Wellfedern, Schraubenfedern und dergleichen.The ball bearing can be arranged in a sleeve, which has at least partially over the outer end faces of the outer part rings drawn edges, wherein between the edges and the end faces, the spring elements are arranged. Thus, the spring elements can reliably press against the inner part rings and / or the outer part rings. As spring elements, all known in the art springs can be considered, in particular disc springs, corrugated springs, coil springs and the like.
In einer Weiterbildung der Erfindung können die Ränder als entlang dem Umfang der Hülse hintereinander angeordnete Federelemente ausgebildet sein. Somit sind die Federelemente und die Hülse einstückig ausgebildet, wodurch der Montageaufwand reduziert wird.In one development of the invention, the edges may be formed as along the circumference of the sleeve one behind the other arranged spring elements. Thus, the spring elements and the sleeve are integrally formed, whereby the assembly cost is reduced.
Die Hülse kann an ihrer Innenwandung im Bereich eines Spaltes zwischen den Teilaußenringen und/oder den Teilinnenringen einen umlaufenden Wulst oder über den Umfang verteilte Noppen aufweisen. Sowohl der Wulst als auch die Noppen können mit der Hülse einstückig aus einem elastisch verformbaren Material hergestellt sein. Auf diese Weise bewirken sie eine wirkungsvolle Abdichtung, so dass ein im Kugellager befindlicher Schmierstoff nicht austreten kann.The sleeve may have on its inner wall in the region of a gap between the outer part rings and / or the partial inner rings a circumferential bead or nubs distributed over the circumference. Both the bead and the nubs can be made in one piece with the sleeve of an elastically deformable material. In this way, they effect an effective seal, so that a lubricant located in the ball bearing can not escape.
Die Hülse kann im Bereich des Spaltes an ihrer Außenwandung ebenfalls einen umlaufenden Wulst oder über den Umfang verteilte Noppen aufweisen. Dieser Wulst oder die Noppen liegt unmittelbar an dem Gehäuse an, in welches das Kugellager eingebaut ist. Folglich existiert zwischen dem Gehäuse und dem Kugellager seitlich von dem Wulst oder den Noppen ein Spalt, so dass das Kugellager innerhalb des Gehäuses etwas verschwenkbar ist. Somit ist die Funktionstüchtigkeit des Kugellagers auch im verschwenkten Zustand möglich. Die Gefahr eines Blockierens oder von Beschädigungen der Lagereinheit infolge von Querkräften, die auf eine in dem Kugellager gelagerte Welle wirken, sind somit reduziert. Der Wulst oder die Noppen können einstückig mit der Hülse hergestellt werden, vorzugsweise aus einem elastischen Material, so dass der Wulst oder die Noppen auch Toleranzen ausgleichen können, die entstehen können, wenn sich das Gehäuse thermisch stärker ausdehnt als die Lagereinheit oder sich diese stärker zusammenzieht als das Gehäuse.The sleeve may also have a circumferential bead or circumferentially distributed nubs in the region of the gap on its outer wall. This bead or nubs lies directly on the housing in which the ball bearing is installed. Consequently, there is a gap between the housing and the ball bearing laterally from the bead or nubs, so that the ball bearing is slightly pivotable within the housing. Thus, the functionality of the ball bearing is possible even in the pivoted state. The risk of jamming or damage to the bearing unit due to lateral forces acting on a shaft mounted in the ball bearing are thus reduced. The bead or nubs may be made integral with the sleeve, preferably of a resilient material, so that the bead or nubs can also compensate for tolerances that may result when the housing thermally expands more than the bearing unit or contracts more strongly as the case.
Zur Fixierung des Kugellagers an dem Gehäuse kann an der Außenumfangsfläche der Hülse mindestens ein Federelement angeordnet sein. Das Federelement kann wulstartig entlang des gesamten Umfangs der Hülse verlaufen und einstückig mit der Hülse ausgeführt sein. Es kann aber auch sein, dass mehrere Federelemente entlang des Außenumfangs der Hülse verteilt sind und mit dieser einstückig verbunden sind. Das Federelement drückt gegen das Gehäuse und kann beim Einschieben in das Gehäuse während der Montage des Kugellagers in einen im Gehäuse befindlichen Hinterschnitt einrasten.For fixing the ball bearing to the housing, at least one spring element may be arranged on the outer peripheral surface of the sleeve. The spring element can run bead-like along the entire circumference of the sleeve and be designed in one piece with the sleeve. But it may also be that a plurality of spring elements are distributed along the outer circumference of the sleeve and are integrally connected thereto. The spring element presses against the housing and can engage when inserted into the housing during assembly of the ball bearing in a housing located in the undercut.
In einer alternativen Ausführungsform der Erfindung können die Teilaußenringe und/oder die Teilinnenringe mit mindestens zwei Klammern gegeneinander gepresst werden. Die Klammern können einstückig mit einem um die Teilaußenringe und/oder die Teilinnenringe herumlaufenden Wulst verbunden sein, wobei der Wulst in dem Spalt zwischen den Teilaußenringen und/oder den Teilinnenringen einpassbar sein kann. Der Wulst vermeidet somit den Austritt des Schmierstoffs. Wenn die Teilinnenringe und/oder die Teilaußenringe an den äußeren Stirnseiten Ausnehmungen zur Aufnahme der Klammern aufweisen, so kann auf diese Weise in axialer Richtung Bauraum eingespart werden.In an alternative embodiment of the invention, the partial outer rings and / or the partial inner rings can be pressed against each other with at least two brackets. The brackets may be integrally connected to a bead running around the partial outer rings and / or the partial inner rings, wherein the bead may be adaptable in the gap between the partial outer rings and / or the partial inner rings. The bead thus avoids the escape of the lubricant. If the partial inner rings and / or the partial outer rings on the outer end faces recesses for receiving the brackets, so can be saved in this way in the axial direction of space.
Die Erfindung betrifft außerdem eine Lenkung für ein Kraftfahrzeug, die erfindungsgemäß die Lagereinheit nach einem der Ansprüche 1 bis 10 aufweist.The invention also relates to a steering for a motor vehicle, which according to the invention comprises the bearing unit according to one of claims 1 to 10.
Nachfolgend werden verschiedene Ausführungsbeispiele der erfindungsgemäßen Lagereinheit anhand der beiliegenden Zeichnungen näher erläutert. Various embodiments of the storage unit according to the invention will be explained in more detail with reference to the accompanying drawings.
