Abstract
Description
Die Erfindung betrifft ein Wälzlager, wie Kugellager, Rollenlager oder Nadellager.The Invention relates to a rolling bearing, such as ball bearings, roller bearings or needle roller bearings.
Die üblichen Wälzlager haben Laufschalen und Wälzkörper, die jeweils aus Stahl bestehen. Die herkömmlichen Lager sind bis zu einer Einsatztemperatur von etwa 200°C geeignet. Für höhere Temperaturen verwendet man keramische Lager, die zwar temperaturbeständig sind, jedoch den Nachteil einer hohen Sprödigkeit haben. Bei Stoß- oder Schlagbeanspruchungen kann das Lager bersten, mit der Folge, dass erhebliche Beschädigungen an Maschinenteilen auftreten können.The usual roller bearing have running shells and rolling elements that each made of steel. The conventional bearings are up to an operating temperature of about 200 ° C suitable. For higher temperatures you use ceramic bearings that are temperature resistant, However, they have the disadvantage of high brittleness. At impact or Impact stresses can rupture the bearing, with the result that considerable damage can occur on machine parts.
Gute Laufeigenschaften erfordern den Einsatz harter Materialien bei den Komponenten eines Wälzlagers. Gehärtete Materialien, wie beispielsweise gehärteter Stahl, sind aber nicht gegen hohe Temperaturen im Bereich von 500°C beständig. Sie verlieren ihre Härte bei hohen Temperaturen.Quality Running properties require the use of hard materials in the Components of a rolling bearing. hardened However, materials such as hardened steel are not resistant to high temperatures in the range of 500 ° C. They lose their hardness high temperatures.
Der Erfindung liegt die Aufgabe zugrunde, ein Wälzlager zu schaffen, das gute Laufeigenschaften und geringen Verschleiß hat, hochtemperaturbeständig ist und eine hohe Berstfestigkeit hat.Of the Invention is the object of the invention to provide a rolling bearing, the good Runnability and low wear has high temperature resistance and has a high bursting strength.
Das Wälzlager nach der vorliegenden Erfindung ist durch den Patentanspruch 1 definiert. Hiernach bestehen die innere und die äußere Laufschale aus Hartmetall und die Wälzkörper bestehen aus Hartmetall oder keramischem Material. Die innere Laufschale ist von einem inneren Stützring abgestützt und die äußere Laufschale ist von einem äußeren Stützring abgestützt.The roller bearing according to the present invention is defined by the patent claim 1. Thereafter, the inner and the outer barrel made of carbide and the rolling elements exist made of tungsten carbide or ceramic material. The inner race is from an inner support ring supported and the outer race is supported by an outer support ring.
Das erfindungsgemäße Wälzlager zeichnet sich dadurch aus, dass die Laufschalen und Wälzkörper aus harten und temperaturbeständigen Materialien bestehen, die geringe Reibungsverluste haben und sich durch hohe Temperaturbeständigkeit auszeichnen. Die Laufschalen, die an sich aus sprödem Material bestehen, sind durch Stützringe abgestützt, welche eine höhere Nachgiebigkeit haben als die Laufschalen. Die Stützringe bilden Stützkörper, die das Bersten der Laufschalen verhindern. Auf diese Weise hat das Wälzlager nicht nur eine hohe Wärmebeständigkeit sondern auch eine hohe Stoßfestigkeit.The Rolling bearing according to the invention is characterized by the fact that the running shells and rolling elements hard and temperature resistant Materials exist that have low friction losses and themselves due to high temperature resistance distinguished. The running shells, which are made of brittle material exist, are by support rings supported, which a higher one Give in as the running shells. The support rings form supporting body, which is the Prevent bursting of the running shells. In this way has the rolling bearing not only a high heat resistance but also a high impact resistance.
Mit den erfindungsgemäßen Werkstoffpaarungen können Lager für Betriebstemperaturen in der Größenordnung von 500°C hergestellt werden.With the material pairings according to the invention can Warehouse for Operating temperatures of the order of magnitude of 500 ° C getting produced.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist die innere Laufschale mit dem inneren Stützring durch eine Hartlotschicht verbunden. In ähnlicher Weise kann die äußere Laufschale mit dem äußeren Stützring durch eine Hartlotschicht verbunden sein. Hartlot ist oxidationsbeständig für Temperaturen bis 650–700°C. Die Hartlotschicht besteht vorzugsweise aus einem Hochtemperatur-Silberlot.According to one preferred embodiment of the invention is the inner race with the inner support ring connected by a brazing layer. Similarly, the outer race with the outer support ring through be connected to a brazing layer. Brazing is resistant to oxidation for temperatures up to 650-700 ° C. The brazing layer preferably consists of a high-temperature silver solder.
Die Lauffläche mindestens einer der beiden Laufschalen kann mit einer Hartstofflaufschicht beschichtet sein. Diese besteht vorzugsweise aus DLC (Diamond like Carbon), AlCrN, AlTiN, CrN oder TiB2 und liefert gute Gleiteigenschaften für die Wälzkörper.The tread at least one of the two running shells can with a hard material layer be coated. This preferably consists of DLC (Diamond like Carbon), AlCrN, AlTiN, CrN or TiB2 and provides good sliding properties for the Rolling elements.
Eine gute Werkstoffkombination mit geringen Reibverlusten ergibt sich, wenn die Laufschalen aus Hartmetall und die Wälzkörper aus SiN oder AlO bestehen. Ebenfalls besteht die Möglichkeit, Lager mit großen Durchmessern herzustellen, da gegenüber rein keramischen Lagern eine erheblich größere Schadenstoleranz besteht. Ein Bersten der Laufschalen wird durch die angelöteten Stützringe verhindert. Die Stützringe bilden jeweils die tragende Struktur des Wälzlagers.A good material combination with low friction losses results, if the running shells are made of carbide and the rolling elements consist of SiN or AlO. It is also possible Warehouse with large Diameters to produce, as compared to purely ceramic bearings a much greater damage tolerance consists. A bursting of the shells is caused by the soldered support rings prevented. The support rings each form the supporting structure of the rolling bearing.
Ein Stützring aus Titan ist vorteilhaft, da Titan einen ähnlichen Ausdehnungskoeffizienten wie Hartmetall besitzt. Alternativ können die Stützringe aus einer Nickellegierung bestehen oder aus ungehärtetem Stahl.One support ring Titanium is advantageous because titanium has a similar expansion coefficient like carbide has. Alternatively, the support rings may be made of a nickel alloy consist of unhardened Stole.
Im Folgenden wird unter Bezugnahme auf die einzige Figur der Zeichnung ein Ausführungsbeispiel der Erfindung näher erläutert. In der Zeichnung ist ein Längsschnitt des erfindungsgemäßen Wälzlagers dargestellt.in the The following will be made with reference to the sole figure of the drawing an embodiment closer to the invention explained. In the drawing is a longitudinal section the rolling bearing of the invention shown.
Bei dem Wälzlager des vorliegenden Ausführungsbeispiels handelt es sich um ein Kugellager. Unter den Begriff „Wälzlager” fallen außerdem Rollenlager, Kegellager und Nadellager und dergleichen.at the rolling bearing of the present embodiment it is a ball bearing. Under the term "rolling bearings" fall Furthermore Roller bearing, taper and needle bearings and the like.
