Die Erfindung betrifft eine Wälzlageranordnung mit einer Vorrichtung zur Vorspannungseinstellung sowie ein Verfahren zum Betrieb eines Wälzlagers.The invention relates to a rolling bearing assembly with a device for bias adjustment and a method for operating a roller bearing.

Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, ein Wälzlager auch unter wechselnden, insbesondere hohen mechanischen und/oder thermischen Belastungen spielfrei zu betreiben.The invention has for its object to operate a roller bearing under varying, especially high mechanical and / or thermal loads backlash.
Zusammenfassung der ErfindungSummary of the invention
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Wälzlageranordnung mit den Merkmalen des Anspruchs 1 sowie durch ein Verfahren zum Betrieb eines Wälzlagers mit den Merkmalen der Anspruch 9. Im Folgenden im Zusammenhang mit der Wälzlageranordnung erläuterte Ausgestaltungen und Vorteile gelten sinngemäß auch für das Verfahren und umgekehrt.This object is achieved by a rolling bearing assembly with the features of
Die Wälzlageranordnung umfasst mindestens eine Reihe, vorzugsweise zwei Reihen, zwischen zwei Lagerringen angeordneter Wälzkörper, sowie eine Vorspannungsregelungseinrichtung, welche eine Vorspannungsmesseinrichtung, eine mit der Vorspannungsmesseinrichtung datentechnisch verknüpfte Regelungsvorrichtung, und eine mit der Regelungsvorrichtung datentechnisch verknüpfte Vorspannungseinstellvorrichtung umfasst, wobei die Vorspannungseinstellvorrichtung als zur Temperierung mindestens eines Lagerrings vorgesehene Temperierungsvorrichtung ausgebildet ist.The rolling bearing assembly comprises at least one row, preferably two rows, between two bearing rings arranged rolling elements, and a bias voltage control device, which comprises a bias measuring device, a data link with the bias voltage associated control device, and with the control device data-linked Vorspannungseinstellvorrichtung, wherein the Vorspannungseinstellvorrichtung than for tempering at least a bearing ring provided Temperierungsvorrichtung is formed.
Mittels der Vorspannungsregelungseinrichtung wird mindestens ein Lagerring derart temperiert, das heißt je nach Bedarf gekühlt oder beheizt, dass sich eine zumindest annähernd konstante Vorspannung zwischen den Lagerringen einstellt. Insbesondere werden zu hohe Vorspannungen, welche sich ansonsten durch temperaturbedingte Abmessungsänderungen an Lagerkomponenten ergeben könnten, zuverlässig vermieden. Ebenso wird jedoch auch vermieden, dass das Lager durch thermisch bedingte Längenänderungen mit Spiel läuft.By means of the bias voltage control device, at least one bearing ring is temperature-controlled, that is, cooled or heated as required, that sets an at least approximately constant bias between the bearing rings. In particular, excessively high bias voltages, which otherwise could result from temperature-induced dimensional changes of bearing components, are reliably avoided. Likewise, however, it is also avoided that the bearing runs through thermally induced changes in length with play.
Die Vorspannungsmesseinrichtung ist in bevorzugter Ausgestaltung zwischen den beiden Wälzkörperreihen angeordnet. Diese Anordnung ist raumsparend sowie mit gutem Schutz vor mechanischer Beschädigung der Messeinrichtung realisierbar. Zudem sind damit die thermischen Verhältnisse an beiden Wälzkörperreihen auf einfache Weise mit einem einzigen Sensor erfassbar.The bias measuring device is arranged in a preferred embodiment between the two rows of rolling elements. This arrangement is space-saving and can be realized with good protection against mechanical damage to the measuring device. In addition, the thermal conditions on both rows of rolling elements can be detected in a simple manner with a single sensor.
Die Vorspannungsmesseinrichtung ist beispielsweise als einen Abstand zwischen den Lagerringen messender Abstandssensor ausgebildet. Alternativ kann auch die Temperaturdifferenz zwischen den Lagerringen zur Ermittlung der Lagervorspannung oder des Lagerspiels verwendet werden. In jedem Fall wird aus den gemessenen Daten automatisch auf die Vorspannung beziehungsweise das Spiel des Lagers geschlossen.The bias voltage measuring device is formed, for example, as a distance between the bearing rings measuring distance sensor. Alternatively, the temperature difference between the bearing rings can be used to determine the bearing preload or the bearing clearance. In any case, from the measured data is automatically closed to the bias or the game of the camp.
Die Temperierungsvorrichtung ist vorzugsweise als fluiddurchströmte, insbesondere flüssigkeitsdurchströmte, Temperierungsvorrichtung ausgebildet. Um die Zuführung des Fluids zu dem zu temperierenden Lagerring möglichst einfach zu gestalten, ist in bevorzugter Ausgestaltung derjenige Lagerring, welcher nicht rotiert, mit einer als Flüssigkeitskühlung ausgebildeten Temperierungsvorrichtung versehen, während der zweite, rotierende Lagerring nicht geregelt temperiert ist.The tempering device is preferably designed as a fluid-flowing, in particular liquid-flow, tempering device. In order to make the supply of the fluid to the bearing ring to be tempered as simple as possible, in a preferred embodiment that bearing ring, which does not rotate, provided with a designed as liquid cooling tempering, while the second, rotating bearing ring is not controlled temperature.
Zur geregelten Temperierung eines Lagerrings kann beispielsweise eine drehzahlgeregelte Pumpe, welche das Kühl- oder Heizmedium durch am Lagerring angeordnete Kanäle pumpt, vorgesehen sein. Auf einfachere Weise kann ein Drosselorgan verwendet werden, welches in den Regelkreis der Temperierung eingebunden ist und die Strömung des Kühl- oder Heizmediums beeinflusst.For controlled temperature control of a bearing ring, for example, a speed-controlled pump which pumps the cooling or heating medium through arranged on the bearing ring channels may be provided. In a simpler way, a throttle body can be used, which is integrated in the control loop of the temperature and affects the flow of the cooling or heating medium.
Das Wälzlager ist vorzugsweise als Axial-Radial-Lagerung ausgebildet. Derartige Lagerungen sind bei Werkzeugmaschinen gängig und arbeiten beispielsweise mit Kugeln als Wälzkörper. Alternativ sind beispielsweise Zylinderrollen als Wälzkörper der erfindungsgemäßen Wälzlageranordnung verwendbar.The rolling bearing is preferably designed as an axial-radial bearing. Such bearings are common in machine tools and work, for example, with balls as rolling elements. Alternatively, for example, cylindrical rollers are usable as rolling elements of the rolling bearing assembly according to the invention.
Zusätzlich zur Vorspannungsregelungseinrichtung ist auch eine Winkelmessvorrichtung in die Wälzlageranordnung integrierbar. Weiter ist ein elektrischer Direktantrieb eines beispielsweise fest mit einem Drehtisch verbundenen Lagerrings realisierbar.In addition to the bias control device and an angle measuring device can be integrated into the rolling bearing assembly. Further, an electric direct drive of a bearing ring, for example, firmly connected to a turntable can be realized.
