Aus
der
Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine Lagerungsanordnung, insbesondere für eine Werkzeugmaschine, anzugeben, bei welcher eine Wälzlagerung und eine Magnetlagerung in besonders vorteilhafter Weise zusammenwirken.Of the Invention is based on the object, a storage arrangement, in particular for a machine tool, specify, in which a rolling bearing and a magnetic bearing cooperate in a particularly advantageous manner.
Zusammenfassung der ErfindungSummary of the invention
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Lagerungsanordnung mit den Merkmalen des Anspruchs 1. Diese Lagerungsanordnung umfasst ein erstes Teil, allgemein als Stator bezeichnet, und ein relativ zum ersten Teil beweglich gelagertes zweites Teil, allgemein als Läufer bezeichnet, wobei zur Lagerung des Läufers auf dem Stator sowohl eine Wälzlagerung als auch eine Magnetlagerung vorgesehen ist. Die Magnetlagerung kompensiert hierbei zumindest teilweise die Gewichtskraft des Läufers und/oder eine auf den Läufer wirkende Bearbeitungskraft. Zu diesem Zweck umfasst die Magnetlagerung Permanentmagnete, die in sich abstoßender, die Wälzlagerung entlastender Anordnung mit dem Stator bzw. mit dem Läufer verbunden sind. In der Regel sind dabei mehrere Permanentmagnete am Stator befestigt und mehrere weitere Permanentmagnete am Läufer befestigt. Im Extremfall ist jeweils ein einziger am Stator bzw. am Läufer befestigter Magnet ausreichend. Unabhängig von der Anzahl der Permanentmagnete weisen gegenüberliegende, relativ zueinander beweglich gelagerte Magnete auf deren einander zugewandten Seiten stets gleichnamige Pole auf. Daraus resultiert eine Magnetkraft, die die Wälzkörper der Wälzlagerung entlastet. Im Vergleich zu einer Wälzlagerung ohne unterstützende Magnetlagerung wird somit der Verschleiß der Wälzlagerung deutlich verringert und damit die Lebensdauer der Lagerungsanordnung erhöht. Erst recht gilt dies im Vergleich zu einer Lagerungsanordnung, welche Permanentmagnete zur Erhöhung der Vorspannung und damit zur Erhöhung der auf die Wälzkörper wirkenden Belastung aufweist.These The object is achieved by a storage arrangement with the features of claim 1. This Storage arrangement comprises a first part, generally as a stator designated, and a relative to the first part movably mounted second Part, generally as a runner designated, wherein for the storage of the rotor on the stator both a rolling bearing as well as a magnetic bearing is provided. The magnetic bearing compensates at least partially for the weight of the runner and / or one on the runner acting processing power. For this purpose, the magnetic bearing comprises permanent magnets, the more repulsive, the rolling bearing Relieving arrangement with the stator or connected to the rotor are. As a rule, several permanent magnets are attached to the stator and several more permanent magnets attached to the rotor. In extreme cases in each case a single magnet attached to the stator or to the rotor is sufficient. Independently of the number of permanent magnets have opposite, relative to each other movably mounted magnets on their sides facing each other always poles of the same name. This results in a magnetic force, the rolling elements of the roller bearing relieved. Compared to a roller bearing without supporting magnetic bearing Thus, the wear of the Rolling bearing clearly reduces and thus increases the life of the storage arrangement. Above all this applies in comparison to a storage arrangement, which permanent magnets to increase the bias and thus to increase acting on the rolling elements Has load.

kann als Linearlager oder als Rotativlager ausgebildet sein. Unter

nicht notwendigerweise geraden Bahn bewegt. Insbesondere kann die
Wälzlagerung
im Fall eines Linearlagers als Kugelumlauf- oder Rollenumlauflager
sowie als Laufrollenführung ausgebildet
sein. Hat die gesamte Lagerungsanordnung die Form eines Rotativlagers,
so kommt als Wälzlager
beispielsweise ein Kugellager, insbesondere ein zweireihiges Schrägkugellager,
oder ein Zylinderrollenlager, insbesondere in Form eines Radial-Axial-Lagers,
in Betracht. Ein Lager der letztgenannten Bauart ist beispielsweise

Nach einer bevorzugten Ausgestaltung sind die Permanentmagnete in mehrreihiger Anordnung mit dem Stator bzw. mit dem Läufer verbunden. Hierbei sind in besonders vorteilhafter Ausgestaltung die einzelnen Permanentmagnete in den verschiedenen Reihen in ungleicher Teilung angeordnet. Dies trägt wesentlich dazu bei, die Abhängigkeit der zwischen Stator und Läufer wirkenden abstoßenden Kraft von der Positionierung des Läufers zu minimieren.To In a preferred embodiment, the permanent magnets are in multi-row Arrangement with the stator or connected to the rotor. Here are in a particularly advantageous embodiment, the individual permanent magnets arranged in different rows in unequal pitch. This contributes significantly in addition, the dependency between the stator and the runner acting repulsive To minimize force from the positioning of the runner.
Eine weitere, mit der vorstehend erläuterten Ausgestaltung kombinierbare Bauform der Lagerungsanordnung umfasst einzelne, Komponenten eines Rotativlagers bildende, ringsegmentartige Permanentmagnete, die insgesamt mindestens einen zur Rotationsachse des Lagers konzentrischen Ring beschreiben. Durch die segmentartige Form der einzelnen Permanentmagnete sind diese praktisch ohne Zwischenräume anordenbar.A further, with the above-described embodiment Combined design of the storage arrangement comprises individual, components a rotativlagers forming, ring-segment-like permanent magnets, the total of at least one concentric with the axis of rotation of the bearing Describe ring. Due to the segment-like shape of the individual permanent magnets These can be arranged practically without gaps.
Nach einer vorteilhaften Weiterbildung sind die am Stator oder am Läufer befestigten Permanentmagnete nicht direkt, sondern mittelbar, nämlich über eine Zwischenplatte, mit dem Stator bzw. mit dem Läufer verbunden. Die Zwischenplatte hat im Vergleich zu dem Stator bzw. zu dem Läufer, den sie kontaktiert, eine geringere spezifische elektrische Leitfähigkeit. Bei der Bewegung des Läufers relativ zum Stator entstehende Wirbelströme werden damit gering gehalten. Als Materialien zur Herstellung der Zwischenplatten sind insbesondere Kunststoff, Sintermetall oder keramische Werkstoffe geeignet. Ebenso können die Zwischenplatten, wie prinzipiell von Elektromotoren bekannt, in Form von Blechpaketen aufgebaut sein.According to an advantageous development, the permanent magnets attached to the stator or to the rotor are not connected directly, but indirectly, namely via an intermediate plate, to the stator or to the rotor. The intermediate plate has a lower specific electrical conductivity compared to the stator or to the rotor, which it contacts. In the movement of the rotor relative to the stator resulting eddy currents are thus kept low. As materials for the production of Intermediate plates are particularly suitable plastic, sintered metal or ceramic materials. Likewise, the intermediate plates, as known in principle from electric motors, be constructed in the form of laminated cores.
In allen Ausführungsformen weist die erfindungsgemäße Lagerungsanordnung gegenüber reinen Wälzlagerungen ohne unterstützende Magnetlagerung den besonderen Vorteil auf, dass die Wälzlagerung aufgrund der unterstützenden Wirkung der Magnetlagerung relativ gering dimensioniert werden kann, wodurch bei geringer Reibung hohe Verfahrgeschwindigkeiten bzw. Drehzahlen ermöglicht werden. Die hohe statische und/oder dynamische Belastbarkeit der gesamten Lagerungsanordnung ist verbunden mit einer für Wälzlagerungen typischen hohen Genauigkeit und Steifigkeit. Die durch die Magnetlagerung gegebene Kraft wirkt vorzugsweise derjenigen Kraft, insbesondere Gewichts- und/oder Bearbeitungskraft, die die Wälzlagerung belastet, exakt entgegen. Sofern die die Magnetlagerung bildenden Permanentmagnete in mehrere Gruppen, insbesondere Reihen, unterteilt sind, wobei in jeder Gruppe eine Anzahl Permanentmagnete mit dem Stator und eine weitere Anzahl Permanentmagnete mit dem Läufer verbunden sind, wirken die abstoßenden magnetischen Kräfte zwischen den Permanentmagneten der ersten Gruppe vorzugsweise in einer Richtung, welche zumindest annähernd parallel zu den Kraftvektoren, die die zwischen Stator und Läufer wirkenden Magnetkräfte, welche durch die Permanentmagnete der mindestens einen weiteren Gruppe erzeugt werden, gerichtet ist. Diese einheitliche Richtung, in welche die durch die Permanentmagnete erzeugten Kräfte wirken, schließt mit der Bewegungsrichtung des Läufers vorzugsweise einen rechten Winkel ein.In all embodiments has the storage arrangement according to the invention across from pure rolling bearings without supportive Magnetic bearing the particular advantage that the rolling bearing because of the supportive Effect of the magnetic bearing can be dimensioned relatively small, whereby at low friction high traversing speeds or Speeds possible become. The high static and / or dynamic load capacity of the entire storage arrangement is associated with one for rolling bearings typical high accuracy and rigidity. The by the magnetic bearing given force preferably acts that force, in particular Weight and / or Processing force, the rolling bearing charged, exactly opposite. If the magnetic bearings forming permanent magnets into several groups, in particular rows, are divided in each group a number of permanent magnets with the stator and a more permanent magnets are connected to the rotor act the repulsive ones magnetic forces between the permanent magnets of the first group preferably in a direction which is at least approximately parallel to the force vectors, the ones between the stator and the runner acting magnetic forces, which by the permanent magnets of at least one other Group is generated, directed. This unified direction, in which act the forces generated by the permanent magnets, includes with the direction of movement of the runner preferably a right angle.
Die Lagerungsanordnung ist je nach Ausführungsform beispielsweise in Werkzeug- und Druckmaschinen, Sondermaschinen, Förderanlagen, Werkstückträgerumlaufsystemen, Nahrungs-, Abfüll- oder Verpackungsanlagen verwendbar. Allgemein ist die Lagerungsanordnung in erster Linie für Anwendungsfälle ge eignet, in denen auf ein Lager von außen Kräfte in definierter, gleich bleibender Richtung wirken.The Storage arrangement is depending on the embodiment, for example in Tool and printing machines, special machines, conveyor systems, workpiece carrier circulation systems, Food, bottling or Packaging systems usable. General is the storage arrangement primarily for use cases ge is suitable in which to a bearing from the outside forces in defined, equal permanent direction.
