Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, ein gegenüber dem genannten Stand der Technik weiterentwickeltes, als Spindellager vorgesehenes Wälzlager anzugeben, welches sich insbesondere durch schmierungstechnisch günstige Eigenschaften, selbst bei höchsten Drehzahlkennwerten, auszeichnet.The invention has for its object to provide a comparison with the cited prior art evolved, provided as a spindle bearing bearings, which is characterized in particular by lubricating favorable properties, even at the highest speed characteristics.
Beschreibung der ErfindungDescription of the invention
Diese Aufgabe wird erfindungsgemäß gelöst durch ein Wälzlager mit den Merkmalen des Anspruchs 1. Weiter wird die Aufgabe gelöst durch ein Verfahren zum Betrieb eines Wälzlagers gemäß Anspruch 8. Im Folgenden im Zusammenhang mit dem Betriebsverfahren erläuterte Ausgestaltungen und Vorteile der Erfindung gelten sinngemäß auch für die Vorrichtung, das heißt das Spindellager, und umgekehrt.This object is achieved by a rolling bearing with the features of claim 1. Further, the object is achieved by a method for operating a rolling bearing according to
Das Wälzlager weist im Wesentlichen zylindrische Wälzkörper auf, welche in einem Käfig geführt sind. Hierbei befindet sich in einer Tasche des Käfigs jeweils eine Wälzkörperanordnung, welche durch einen einzelnen oder durch mehrere Wälzkörper gebildet sein kann. Die Wälzkörper rollen auf Bauteilen ab, die ohne Beschränkung der Allgemeinheit als Innenring und Außenring bezeichnet werden können. Diese Bezeichnungen sind rein funktional zu verstehen; tatsächlich kann anstelle eines Innenrings beispielsweise auch eine Welle und anstelle eines Außenrings beispielsweise auch ein Gehäuse vorgesehen sein. In jedem Fall weist jede Wälzkörperanordnung mindestens eine von ihren Stirnseiten beabstandete Verjüngung auf.The rolling bearing has substantially cylindrical rolling elements, which are guided in a cage. In each case a rolling body arrangement, which can be formed by a single or by a plurality of rolling elements, is located in a pocket of the cage. The rolling elements roll on components, which can be referred to without restriction of generality as inner ring and outer ring. These terms are purely functional; in fact, instead of an inner ring, for example, also a shaft and instead of an outer ring, for example, also a housing may be provided. In any case, each rolling element arrangement has at least one taper spaced from its end faces.
Die Verjüngung kann entweder durch eine in einen Wälzkörper eingearbeitete Nut oder, im Fall von mehreren aneinander grenzenden, zusammen eine Wälzkörperanordnung bildenden Wälzkörpern, an einer Stoßstelle zwischen Wälzkörpern gebildet sein. In beiden Fällen sind durch die Verjüngung offene Querschnittsbereiche zwischen der Wälzkörperanordnung und dem Innen- bzw. Außenring gebildet. Die Käfigführung jeder Wälzkörperanordnung sorgt gleichzeitig dafür, dass die Bereiche innerhalb des Querschnitts des Wälzlagers, in denen durch die Verjüngung Öffnungen für den Durchtritt von Schmiermittel gebildet sind, beim Betrieb des Wälzlagers nicht wandern. Das Wälzlager ist damit für sehr hohe Drehzahlkennwerte von mindestens 500.000 min–1 mm, beispielsweise mehr als 750.000 min–1 mm, insbesondere mehr als 1.000.000 min–1 mm, geeignet. Der Käfig des Wälzlagers ist vorzugsweise am Außenring geführt. Bei der Schmierung des Wälzlagers handelt es sich in bevorzugter Ausgestaltung um eine Luft-Öl-Schmierung.The taper may be formed either by a groove incorporated in a rolling element or, in the case of a plurality of adjacent rolling elements which together form a rolling element arrangement, at a joint between rolling elements. In both cases, open cross-sectional areas between the Wälzkörperanordnung and the inner and outer ring are formed by the taper. At the same time, the cage guide of each rolling element arrangement ensures that the regions within the cross section of the rolling bearing, in which openings for the passage of lubricant are formed by the taper, do not migrate during operation of the rolling bearing. The rolling bearing is thus suitable for very high speed characteristics of at least 500,000 min -1 mm, for example more than 750,000 min -1 mm, in particular more than 1,000,000 min -1 mm. The cage of the rolling bearing is preferably guided on the outer ring. The lubrication of the rolling bearing is in a preferred embodiment to an air-oil lubrication.
Gemäß einer möglichen Ausführungsform weist jede Wälzkörperanordnung nur eine einzige Verjüngung auf. Im Fall der Bildung der Wälzkörperanordnung durch einen einzigen Wälzkörper ist die Verjüngung vorzugsweise in der Mitte des Wälzkörpers angeordnet. Ebenso sind auch Wälzkörperformen realisierbar, bei welchen sich eine einzige Verjüngung asymmetrisch in der Mantelfläche befindet. In analoger Weise kann im Fall der Bildung der Wälzkörperanordnung durch zwei aneinanderstoßende Wälzkörper entweder die Verwendung von zwei gleich breiten oder von zwei ungleich breiten Wälzkörpern vorgesehen sein.According to a possible embodiment, each rolling element arrangement has only a single taper. In the case of forming the rolling element assembly by a single rolling element, the taper is preferably arranged in the center of the rolling element. Likewise, rolling element shapes can be realized in which a single taper is asymmetrically in the lateral surface. In an analogous manner, in the case of the formation of the rolling body assembly by two abutting rolling elements either the use of two equally wide or two unequal width rolling elements can be provided.
Bei einer möglichen geometrischen Variante der Verjüngung ist diese ausschließlich durch eine gekrümmte Kontur beschrieben, wobei beispielsweise kreisbogenförmige Konturen und/oder sonstige gekrümmte Konturen, etwa elliptische oder logarithmische Konturen, gegeben sein können.In a possible geometric variant of the taper this is described exclusively by a curved contour, for example, circular-arc contours and / or other curved contours, such as elliptical or logarithmic contours, may be given.
In anderen möglichen Varianten weist die Verjüngung des Wälzkörpers mindestens eine gerade Kontur auf. Ein gerader Konturabschnitt kann mit einem gekrümmten Konturabschnitt beliebiger Art kombiniert sein. In allen Fällen sind die Übergänge zwischen dem verjüngten und dem zylindrischen Teil der Mantelfläche des Wälzkörpers in vorteilhafter Weise abgerundet gestaltet. Die in radialer Richtung des Wälzkörpers gemessene Tiefe der Verjüngung beträgt in bevorzugter Ausgestaltung zwischen 0,02 mm und 1,5 mm. Der Betrag der Tiefe kann mehr als 5 % des Wälzkörperdurchmessers sein.In other possible variants, the taper of the rolling element has at least one straight contour. A straight contour section can be combined with a curved contour section of any type. In all cases, the transitions between the tapered and the cylindrical part of the lateral surface of the rolling body are advantageously rounded rounded. The depth of the taper measured in the radial direction of the rolling element is in a preferred embodiment between 0.02 mm and 1.5 mm. The amount of depth may be more than 5% of the rolling element diameter.
Die als modifizierte Zylinderrollen gestalteten Wälzkörper des Wälzlagers sind entweder aus Stahl oder aus einem keramischen Werkstoff, beispielsweise Siliciumnitrid, gefertigt. The designed as a modified cylindrical rollers rolling elements of the bearing are made of either steel or a ceramic material, such as silicon nitride.
