Abstract
Description
Die Erfindung betrifft ein Wälzlager mit einem Lageraußenring und einem Lagerinnenring.The The invention relates to a rolling bearing with a bearing outer ring and a bearing inner ring.
Aus dem Stand der Technik sind allgemein Wälzlager, wie beispielsweise Kugellager, mit einem niedrigen Axialspiel bekannt, die jedoch nur geringe Schwenkbewegungen erlauben und keine Dämpfungseigenschaften in axialer Richtung aufweisen. Ferner sind Vier-Punkt-Lager bekannt, die zwar ein sehr niedriges Axialspiel aufweisen, jedoch keine nennenswerte Schwenkbewegung des Vier-Punkt-Lagers und ebenfalls keine Dämpfung ermöglichen. Um das Vier-Punkt-Lager schwenkbar zu gestalten, kann ein zusätzlicher Lagering vorgesehen sein. Jedoch weist ein solches Lager ebenfalls keine Dämpfungswirkung auf und kann nur noch geringe Axialkräfte aufnehmen.Out The prior art are generally rolling bearings, such as Ball bearings, known with a low axial clearance, but only allow small pivoting movements and no damping properties in the axial Have direction. Furthermore, four-point bearings are known, although have a very low axial play, but not significant Swivel movement of the four-point bearing and also no damping allow. To make the four-point bearing pivotable, an additional Storage be provided. However, such a bearing also has no damping effect and can only absorb low axial forces.
Die Erfindung hat die Aufgabe, ein Wälzlager der eingangs genannten Art dahingehend zu verbessern, dass es trotz minimalem Axialspiel Schwenkbewegungen ermöglicht und außerdem Dämpfungseigenschaften aufweist.The Invention has the task of a rolling bearing of to improve the above-mentioned type in that it despite minimal axial play allows for swivel movements and also damping properties having.
Die Erfindung löst die gestellte Aufgabe durch ein Wälzlager der eingangs genannten Art, bei dem erfindungsgemäß der Lageraußenring und/oder der Lagerinnenring jeweils zwischen mindestens einem Dämpfungselement angeordnet ist. Mit Hilfe des Dämpfungselementes können auf das Wälzlager wirkende Stöße und Schwingungen aufgenommen werden. Somit ist durch das Dämp fungselement eine akustische Entkopplung des Wälzlagers von den das Wälzlager umgebenden Bauteilen möglich bei gleichzeitig höherer Lagerbelastung und somit höherer Lebensdauer. Ferner ermöglicht das Dämpfungselement dem Wälzlager eine Schwenkbewegung um eine radiale Schwenkachse durchzuführen. Ein zusätzlicher Lagerring zur Realisierung der Schwenkbewegung kann also zukünftig entfallen, da lediglich die Schwenkeinheit des Wälzlagers geometrisch möglich sein muss. Durch das Dämpfungselement wird das Wälzlager insgesamt einfacher und komfortabler, da das Dämpfungselement sowohl eine Dämpfungsfunktion als auch eine Schwenkfunktion ermöglicht.The Invention solves the task posed by a rolling bearing of the aforementioned Kind, in the present invention, the bearing outer ring and / or the bearing inner ring in each case between at least one damping element is arranged. With the help of the damping element can on the rolling bearing acting shocks and vibrations be recorded. Thus, by the Dämp tion element is an acoustic Decoupling of the rolling bearing from the rolling bearing surrounding components possible at the same time higher Bearing load and thus higher Lifespan. Furthermore allows the damping element the rolling bearing to perform a pivoting movement about a radial pivot axis. One additional Bearing ring for the realization of the pivoting movement can therefore be omitted in the future, since only the pivot unit of the bearing be geometrically possible got to. By the damping element is the rolling bearing overall easier and more comfortable because the damping element both a damping function as well as a swivel function allows.
In einer bevorzugten Ausführungsform kann das mindestens eine Dämpfungselement den Lageraußenring und/oder den Lagerinnenring wenigstens teilweise umgreifen. Somit ermöglicht das Dämpfungselement als ein einziges und einfach gestaltetes Bauteil eine axiale und eine radiale Dämpfung sowie die Durchführung und Dämpfung der Schwenkbewegung.In a preferred embodiment this can be at least one damping element the bearing outer ring and / or enclose the bearing inner ring at least partially. Consequently allows the damping element as a single and simply designed component an axial and a radial damping as well as the implementation and damping the pivoting movement.
In einer alternativen Ausführungsform ist es jedoch auch möglich, dass an jeder Stirnseite des Lageraußenrings und/oder des Lagerinnenrings jeweils ein Dämpfungselement angeordnet ist. Dieses Dämpfungselement übernimmt dann die Dämpfung in axialer Richtung und die Dämpfung der Schwenkbewegung und ermöglicht außerdem die Bewegung in axialer Richtung und die Schwenkbewegung des Wälzlagers.In an alternative embodiment but it is also possible that on each end face of the bearing outer ring and / or the bearing inner ring one damping element each is arranged. This damping element takes over then the damping in axial direction and damping the pivoting movement and allows Furthermore the movement in the axial direction and the pivoting movement of the rolling bearing.
Alternativ oder zusätzlich kann ein weiteres Dämpfungselement am Außenumfang des Lageraußenrings und/oder am Innenumfang des Lagerinnenrings angeordnet sein. Das weitere Dämpfungselement ist dann für die Dämpfung in radialer Richtung zuständig. Die Verwendung von unterschiedlichen Dämpfungselementen für die Dämpfung in axialer und radialer Richtung ermöglicht eine unterschiedliche Werkstoffauswahl, um verschiedene Dämpfungseigenschaften in radialer und axialer Richtung zu realisieren.alternative or additionally can be another damping element on the outer circumference of the bearing outer ring and / or be arranged on the inner circumference of the bearing inner ring. The further damping element is then for the damping responsible in the radial direction. The use of different damping elements for damping in axial and radial direction allows a different Material selection to different damping properties in radial and to realize axial direction.
Die Schwenkbewegung kann durch die entsprechend gestalteten Dämpfungselemente und/oder durch ein Freistellen des Wälzlagers und/oder durch eine geeignete geometrische Gestaltung des Wälzlagers und/oder durch eine geeignete geometrische Gestaltung der das Wälzlager umgebenden Bauteile ermöglicht werden. So kann beispielsweise der Lageraußenring eine konvexe Wölbung an seinem Außenumfang aufweisen. Außerdem ist es möglich; dass eine Welle, auf welcher der Lagerinnenring sitzt, eine konvexe Wölbung aufweist. Durch die konvexe Wölbung des Außenumfangs des Lageraußenrings und/oder der Welle lässt sich das Wälzlager besonders gut verschwenken. Die Wölbung ist außerdem eine konstruktiv einfache Lösung, die fertigungstechnisch einfach und preiswert zu verwirklichen ist.The Pivoting movement can by the appropriately designed damping elements and / or by an exemption of the rolling bearing and / or by a suitable geometric design of the rolling bearing and / or by a suitable geometric design of the rolling bearing surrounding components allows become. For example, the bearing outer ring to a convex curvature its outer circumference exhibit. Furthermore Is it possible; that a shaft on which the bearing inner ring sits, a convex bulge having. Due to the convex curvature the outer circumference of the bearing outer ring and / or the wave can be the rolling bearing turn very well. The vault is also one structurally simple solution, the manufacturing technology is simple and inexpensive to implement.
Alternativ oder zusätzlich ist es jedoch auch möglich, dass ein Sitz des Lageraußenrings eine konkave Wölbung aufweist. Ebenso kann der Lagerinnenring konkav gewölbt sein.alternative or additionally but it is also possible that a seat of the bearing outer ring a concave curvature having. Likewise, the bearing inner ring may be concave.
An dem mindestens einen Dämpfungselement kann mindestens ein konzentrisch zum Wälzlager angeordneter Distanzring anliegen. Der Distanzring erzeugt einen definierten Einbauraum für das Dämpfungselement und schützt dieses gegebenenfalls vor Beschädigungen. Somit stellt der konzentrisch zum Wälzlager angeordnete Distanzring eine optimale Dämpfungswirkung des Dämpfungselements sicher. Außerdem begrenzt der Distanzring Schwenkbewegungen und/oder Radialbewegungen. Ein axialer Abstand zwischen dem Wälzlager und den das Wälzlager umgebenden Bauteilen ermöglicht die Axial- und Schwenkbewegung. Somit steht dem Wälzlager ein Bewegungsspielraum zur Verfügung, der benötigt wird, um Stöße und Schwingungen, die auf das Wälzlager einwirken, zu dämpfen.On the at least one damping element may be present at least one concentric with the rolling bearing arranged spacer ring. The spacer ring creates a defined installation space for the damping element and protects it if necessary from damage. Thus, the concentric with the roller bearing arranged spacer ring ensures optimal damping effect of the damping element. In addition, the spacer ring limits pivoting movements and / or radial movements. An axial distance between the rolling bearing and the rolling bearing surrounding components allows the axial and pivotal movement. Thus stands the rolling bearing a movement margin available, which is needed to absorb shocks and vibrations acting on the rolling bearing.
Aufgrund der guten Dämpfungseigenschaften kann das Dämpfungselement aus einem Kunststoff oder aus einem Elastomer gefertigt sein.by virtue of the good damping properties can the damping element be made of a plastic or an elastomer.
Es ist jedoch auch möglich, dass das Dämpfungselement eine Metallfeder ist. So kann das Dämpfungselement beispielsweise eine Tellerfeder oder eine Wellfeder sein.It but it is also possible that the damping element a metal spring is. For example, the damping element a diaphragm spring or a wave spring.
Wenn das mindestens eine Dämpfungselement aus einem Kunststoff oder aus einem Elastomer gefertigt ist, kann es mit Aussparungen versehen sein. Durch die Aussparungen kann die Steifigkeit des Dämpfungselementes in axialer und/oder in radialer Richtung unabhängig voneinander genau eingestellt werden. Die Anbringung von Aussparungen ist besonders dann sinnvoll, wenn für die Dämpfung in axialer und radialer Richtung derselbe Werkstoff ausgewählt werden soll. Das ist beispielsweise dann der Fall, wenn das Dämpfungselement den Lageraußenring und/oder den Lagerinnenring wenigstens teilweise umgreift, weil dann ein und dasselbe Dämpfungselement in radialer und in axialer Richtung die Dämpfungsfunktion übernimmt.If the at least one damping element is made of a plastic or an elastomer can it can be provided with recesses. Through the recesses, the Stiffness of the damping element set in the axial and / or radial direction independently of each other exactly become. The attachment of recesses is particularly useful then if for the damping be selected in the axial and radial directions of the same material should. This is the case, for example, when the damping element the bearing outer ring and / or the bearing inner ring at least partially surrounds, because then one and the same damping element assumes the damping function in the radial and in the axial direction.
Um im Falle eines Versagens des Dämpfungselementes trotzdem eine Kraftübertragung auf das Wälzlager zu gewährleisten, kann ein Anschlag die Bewegungsfreiheit des Wälzlagers in axialer und/oder in radialer Richtung begrenzen. Außerdem kann der Anschlag im Versagensfall des Dämpfungselementes auch die Schwenkbewegung des Wälzlagers begrenzen.Around in case of failure of the damping element nevertheless a power transmission on the rolling bearing to ensure, a stop the freedom of movement of the bearing in the axial and / or limit in the radial direction. In addition, the stop in the Failure of the damping element also the pivoting movement of the rolling bearing limit.
Der Lageraußenring kann einen umlaufenden Absatz aufweisen. Der Absatz kann dann das den Lageraußenring teilweise umgreifende Dämpfungselement aufnehmen.Of the Bearing outer ring can have a circumferential paragraph. The paragraph can then be the Bearing outer ring partially encompassing damping element take up.
Damit das erfindungsgemäße Wälzlager auch ein möglichst geringes Axialspiel aufweist, kann es ein Vier-Punkt-Kugellager sein.In order to the rolling bearing according to the invention also one possible low axial play, it can be a four-point ball bearing be.
Nachfolgend werden verschiedene Ausführungsbeispiele des erfindungsgemäßen Wälzlagers anhand der beiliegenden Zeichnungen näher erläutert.following Be different embodiments of the rolling bearing according to the invention the accompanying drawings closer explained.
