Wälzlagerroller bearing
Die Erfindung betrifft ein Wälzlager, bestehend aus einem Innenring, einem Außenring und zwischen Innenring und Außenring angeordneten Wälzkörpern.The invention relates to a rolling bearing consisting of an inner ring, an outer ring and rolling elements arranged between the inner ring and the outer ring.
Als Ausgangsmaterial für die Fertigung der Ringe eines Wälzlagers ist es aus der US 5,866,647 bekannt geworden, einen Faserverbundwerkstoff einzusetzen, bei dem die Festigkeit des Materials durch Glasfasern oder ähnliche Fasermaterialien erhöht wird. Ein solches Material zeichnet sich im Vergleich zu Stahl durch ein geringeres Gewicht aus. Weiterhin ist die Korrosionsbeständigkeit hoch und die thermische Ausdehnung gering.As a starting material for the production of the rings of a rolling bearing, it has become known from US 5,866,647 to use a fiber composite material in which the strength of the material is increased by glass fibers or similar fiber materials. Such a material is characterized by a lower weight compared to steel. Furthermore, the corrosion resistance is high and the thermal expansion is low.
Es hat sich dabei jedoch als nachteilhaft herausgestellt, dass es im Bereich der Laufflächen für den Anlauf der Wälzkörper zu vorzeitigem Verschleiß kommen kann.However, it has been found to be disadvantageous that premature wear can occur in the area of the running surfaces where the rolling elements start.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Lager der eingangs genannten Art so weiterzuentwickeln, dass zwar die Vorteile des Faserverbundwerkstoffs für ein Wälzlager genutzt werden können, dass andererseits das Verschleißverhalten des Wälzlagers hierdurch nicht nachteilhaft beeinflusst wird.The invention is therefore based on the object of further developing a bearing of the type mentioned at the outset in such a way that the advantages of the fiber composite material can be used for a rolling bearing, but that on the other hand the wear behavior of the rolling bearing is not disadvantageously influenced thereby.
f «9 ·» I» ♦· ·f «9 ·» I» ♦· ·
Zur Lösung dieser Aufgabe sieht die vorliegende Erfindung bei dem eingangs beschriebenen Wälzlager vor, dass sowohl am Innenring als auch am Außenring metallische Drähte, insbesondere Stahldrähte, zum Anlauf der Wälzkörper angeordnet sind und dass zumindest einer der Lagerringe, vorzugsweise beide Lagerringe, zumindest teilweise aus Faserverbundwerkstoff bestehen.To achieve this object, the present invention provides for the rolling bearing described at the outset that metallic wires, in particular steel wires, are arranged on both the inner ring and the outer ring for the starting of the rolling elements and that at least one of the bearing rings, preferably both bearing rings, consist at least partially of fiber composite material.
Die Lagerringe selber werden also im wesentlichen, bevorzugt vollständig, aus Faserverbundwerkstoff hergestellt. Die Anlaufflächen für die Wälzkörper werden jedoch durch Drähte gebildet, die in das Faserverbundmaterial eingelagert werden.The bearing rings themselves are essentially, preferably completely, made of fiber composite material. However, the contact surfaces for the rolling elements are formed by wires that are embedded in the fiber composite material.
Die den Faserverbundwerkstoff bildenden Fasern können mit Vorteil Kohlefasern oder Glasfasern sein. Diese Fasern werden durch ein geeignetes Harzmaterial, wie im Stand der Technik bekannt, miteinander verbunden.The fibers forming the fiber composite material can advantageously be carbon fibers or glass fibers. These fibers are bonded together by a suitable resin material, as known in the art.
Das erfindungsgemäße Lager wird vorzugsweise als Drehkranzlager oder als Schwenklager ausgebildet. Dabei wird der Vorteil genutzt, dass sich bei derartig großen Lagern das niedrige Gewicht des Faserverbundwerkstoffs besonders bewährt.The bearing according to the invention is preferably designed as a slewing ring bearing or as a pivot bearing. The advantage is used here that the low weight of the fiber composite material is particularly useful for such large bearings.
Gemäß einer Weiterbildung ist vorgesehen, dass der Innenring und/oder der Außenring des Lagers mit Gewindeeinsätzen oder Durchgangsbohrungen versehen ist, über die Anbauteile an den Ringen befestigt sind. Bei diesen Anbauteilen kann es sich um ringförmige Anschlussteile handeln.According to a further development, the inner ring and/or the outer ring of the bearing is provided with threaded inserts or through holes via which attachments are attached to the rings. These attachments can be ring-shaped connecting parts.
Insbesondere bei großen Lagern kann mit Vorteil vorgesehen werden, dass ;oimindest einer der Lagerringe kreissegmentartig geteilt ausgebildet ist.Particularly in the case of large bearings, it can be advantageous to provide that at least one of the bearing rings is divided into circular segments.
In die aus Faserverbundwerkstoff bestehenden Lagerringe können weiterhin Funktionselemente integriert sein. Hierbei ist insbesondere an elektrische Wicklungen oder an Verzahnungen gedacht.Functional elements can also be integrated into the bearing rings made of fiber composite material. This particularly includes electrical windings or gears.
Das beschriebene Lager zeichnet sich durch ein im Vergleich zu herkömmlichen Lagern geringeres Gewicht aus. Es hat eine geringe thermische Ausdehnung und ist beständig gegen Korrosion. Es hat auch günstigere Eigenschaften hinsichtlich der Ortung mittels Infrarot-Anlagen, was sich bei militärischen Anwendung vorteilhaft bemerkbar macht. Trotzdem ist die Gebrauchsdauer des Lagers beim Einsatz des Faserverbundwerkstoffs unverändert hoch, da zum Anlauf der Wälzkörper übliche Laufdrähte aus Stahl zum Einsatz kommen.The bearing described is characterized by its lower weight compared to conventional bearings. It has low thermal expansion and is resistant to corrosion. It also has better properties when it comes to location using infrared systems, which is advantageous in military applications. Despite this, the service life of the bearing remains high when using the fiber composite material, since conventional steel running wires are used to start the rolling elements.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigen:An embodiment of the invention is shown in the drawing. It shows:
Figur 1 schematisch in dreidimensionaler Ansicht den Schnitt durch ein Drehkranzlager,Figure 1 shows a schematic three-dimensional view of a section through a slewing ring bearing,
Figur 2 schematisch den Radialschnitt durch ein ähnliches Lager.Figure 2 shows a schematic radial section through a similar bearing.
In Figur 1 ist ein Wälzlager 1 dargestellt, das aus einem Innenring 2 und einem Außenring 3 besteht. Zwischen Innenring und Außenring sind Wälzkörper 4 angeordnet.Figure 1 shows a rolling bearing 1 consisting of an inner ring 2 and an outer ring 3. Rolling elements 4 are arranged between the inner ring and the outer ring.
Den Anlauf für die Wälzkörper 4 bilden Laufdrähte 5, die aus Stahl bestehen und mit dem Innenring bzw. Außenring verbunden sind. Das Grundmaterial des ][nnenrings 2 und des Außenrings 3 ist ein Faserverbundwerkstoff auf metallischer Basis. Hierzu sind in das metallische Grundmaterial Kohlefasern und/oder Glasfasern eingelagert. Diese Fasern erhöhen die Festigkeit des Materials erheblich, während gleichzeitig die Dichte des Materials im Vergleich zu reinem Metall abnimmt. Details hierzu sind in der US 5,866,647 dargestellt.The starting point for the rolling elements 4 is formed by running wires 5, which are made of steel and are connected to the inner ring and outer ring respectively. The base material of the inner ring 2 and the outer ring 3 is a fiber composite material on a metallic basis. For this purpose, carbon fibers and/or glass fibers are embedded in the metallic base material. These fibers increase the strength of the material considerably, while at the same time the density of the material decreases in comparison to pure metal. Details of this are shown in US 5,866,647.
In die Ringe sind Gewindebohrungen 6 eingearbeitet, über die Anbauteile 7 befestigt werden können.Threaded holes 6 are machined into the rings through which attachments 7 can be attached.
In Figur 2 ist eine ähnliche Ausführungsform dargestellt, wobei als Wälzkörper 4 Kugeln zum Einsatz kommen.Figure 2 shows a similar embodiment, where 4 balls are used as rolling elements.
Wie bei Drahtwälzlagem üblich, ist insbesondere vorgesehen, dass zumindest einer der Ringe geteilt ausgebildet ist. Zwischen den beiden Teilringen ist ein Distanzelement eingelegt, so dass bei der Montage des Lagers eine definierte Vorspannung der Lagerringe über die Laufdrähte auf die Wälzkörper ausgeübt wird.As is usual with wire roller bearings, it is particularly intended that at least one of the rings is split. A spacer element is inserted between the two partial rings so that when the bearing is assembled, a defined preload of the bearing rings is exerted on the rolling elements via the running wires.
