Description

Hochbelastbare drehfeste Verbindung  Heavy-duty non-rotatable connection
Die Erfindung betrifft eine Anordnung nach dem Oberbegriff von Anspruch 1. The invention relates to an arrangement according to the preamble of claim 1.
Die Druckschrift EP 2 075466 B1 offenbart ein reibungserhöhendes Mittel mit einer Beschichtung, die ein Pulver mit Körnern aus Diamant enthält. Das Mittel dient dazu, eine niedertourige Hauptwelle einer Windturbine drehfest mit einer Eingangswelle eines Getriebes zu verbinden. Durch das reibungserhöhende Mittel erhöht sich der Reibungskoeffizient zwischen der Hauptwelle und der Eingangswelle. Auf diese Weise lassen sich ohne Änderung der Abmaße der Bauteile höhere Drehmomente übertragen. The document EP 2 075466 B1 discloses a friction-increasing agent with a coating containing a powder with grains of diamond. The means serves to rotatably connect a low-speed main shaft of a wind turbine with an input shaft of a transmission. The friction increasing means increases the friction coefficient between the main shaft and the input shaft. In this way, higher torque can be transmitted without changing the dimensions of the components.
Als Trägermaterial eignet sich Kunststoff. Dieser altert allerdings und ist nicht hinreichend beständig gegen Bestandteile des verwendeten Getriebeöls. Daher besteht die Gefahr, dass Diamantpartikel sich lösen und in das Getriebe gelangen. Dieses Problem besteht auch, wenn das reibungserhöhende Mittel dynamischen Belastungen unterworfen ist oder auf Biegung beansprucht wird. As a carrier material is plastic. This, however, ages and is not sufficiently resistant to components of the gear oil used. Therefore, there is a risk that diamond particles will come loose and get into the transmission. This problem also exists when the friction-increasing agent is subjected to dynamic loads or is subjected to bending.
Der Erfindung liegt die Aufgabe zugrunde, Beschädigungen des Getriebes infolge sich lösender Partikel zu vermeiden. The invention has for its object to avoid damage to the transmission due to loosening particles.
Diese Aufgabe wird gelöst durch eine Anordnung nach Anspruch 1. Bevorzugte Weiterbildungen sind in den Unteransprüchen enthalten. This object is achieved by an arrangement according to claim 1. Preferred developments are contained in the subclaims.
Die Anordnung umfasst eine erste drehbare Komponente und eine zweite drehbare Komponente. Bei der ersten Komponente kann es sich um eine erste Welle, insbesondere die Hauptwelle einer Windturbine, oder einen ersten Kupplungsflansch handeln. Entsprechend kann es sich bei der zweiten Komponente um eine zweite Welle, insbesondere eine Eingangswelle eines Getriebes der Windkraftanlage, eine Nabe oder einen zweiten Kupplungsflansch handeln. The assembly includes a first rotatable component and a second rotatable component. The first component may be a first shaft, in particular the main shaft of a wind turbine, or a first coupling flange. Accordingly, the second component may be a second shaft, in particular an input shaft of a transmission of the wind turbine, a hub or a second coupling flange.
Die Anordnung umfasst darüber hinaus mindestens ein Trägermaterial und Partikel. Die Partikel haften in dem Trägermaterial, d.h. zwischen dem Trägermaterial und den einzelnen Partikel bestehen formschlüssige und/oder stoffschlüssige Verbindungen. Insbesondere können die Partikel in das Trägermaterial eingelassen sein. Dies bedeutet, dass jeder Partikel mindestens teilweise von dem Trägermaterial umschlossen ist. The assembly further comprises at least one carrier material and particles. The particles adhere in the carrier material, ie between the carrier material and the individual particles are positive and / or material connections. In particular, the particles can be embedded in the carrier material. This means that each particle is at least partially enclosed by the carrier material.
Die Partikel zeichnen sich dadurch aus, dass sie aus einem Material bestehen, das härter ist als das Material der ersten Komponente und der zweiten Komponente. Insbesondere können die Partikel aus Sintermaterial oder Diamant bestehen. The particles are characterized in that they are made of a material that is harder than the material of the first component and the second component. In particular, the particles may consist of sintered material or diamond.
Zwischen der ersten Komponente und der zweiten Komponente verläuft mindestens ein Spalt, in dem sich das Trägermaterial mit den Partikeln befindet. Between the first component and the second component extends at least one gap in which the carrier material is located with the particles.
Für die Anordnung des Trägermaterials mit den Partikeln in dem Spalt gibt es verschiedene Alternativen. So ist es möglich, als Trägermaterial Klebstoff zu verwenden. Die Partikel können dann direkt auf der ersten Komponente und/oder der zweiten Komponente verklebt werden. Auch ist es möglich, eine Einlage zu verwenden, etwa eine Beilagscheibe, auf welche die Partikel aufgeklebt werden. Die Einlage besteht bevorzugt aus Metall. For the arrangement of the carrier material with the particles in the gap, there are various alternatives. So it is possible to use as a carrier adhesive. The particles can then be bonded directly to the first component and / or the second component. It is also possible to use an insert, such as a washer on which the particles are adhered. The insert is preferably made of metal.
Auch ist es möglich, Kunststoff als Trägermaterial zu verwenden. Der Kunststoff dient zugleich als Einlage, die zusammen mit den Partikeln in den Spalt eingesetzt werden kann. It is also possible to use plastic as a carrier material. The plastic also serves as an insert, which can be used together with the particles in the gap.
Die erste Komponente und die zweite Komponente sind gegen das Trägermaterial mit den Partikeln verspannt. Dies dient dazu, eine drehfeste Verbindung zwischen der ersten Komponente und der zweiten Komponente herzustellen. Das Trägermaterial mit den Partikeln erfüllt dabei den Zweck des in der Druckschrift EP 2 075 466 B1 beschriebenen reibungserhöhenden Mittels. The first component and the second component are braced against the carrier material with the particles. This serves to establish a rotationally fixed connection between the first component and the second component. The carrier material with the particles thereby fulfills the purpose of the friction-increasing agent described in the document EP 2 075 466 B1.
Zur Verspannung der ersten Komponente und der zweiten Komponente gegen das Trägermaterial mit den Partikeln eignet sich etwa ein Schraubflansch. Dabei bildet die erste Komponente eine erste Hälfte des Schraubflansches und die zweite Komponente eine zweite Hälfte des Schraubflansches. Zwischen die beiden Hälften wird das Trägermaterial mit den Partikeln eingebracht. Eine drehfeste Verbindung kommt durch Verschrauben der beiden Hälften zustande. Auch ist es möglich, die erste Komponente und die zweite Komponente zu verbinden, indem eine Presspassung in dem Spalt erzeugt wird, etwa durch Eindehnen und/oder Aufschrumpfen. For bracing the first component and the second component against the carrier material with the particles is about a screw. In this case, the first component forms a first half of the screw and the second component a second half of the screw. Between the two halves becomes introduced the carrier material with the particles. A non-rotatable connection is achieved by screwing the two halves together. It is also possible to join the first component and the second component by creating an interference fit in the gap, such as by shrinking and / or shrinking.
Um zu verhindern, dass die Partikel aus dem Spalt austreten, ist erfindungsgemäß mindestens eine Dichtung vorgesehen, die den Spalt abdichtet. Die Dichtung verläuft zwischen der ersten Komponente und der zweiten Komponente und überbrückt dabei den Spalt. Dort, wo die Dichtung verläuft, können keine Partikel mehr aus dem Spalt austreten. Durch die mindestens eine Dichtung wird der Spalt zu einem geschlossenen Hohlraum. In order to prevent the particles from escaping from the gap, according to the invention at least one seal is provided which seals the gap. The seal extends between the first component and the second component, bridging the gap. Where the seal passes, no particles can escape from the gap. Due to the at least one seal, the gap becomes a closed cavity.
Als Dichtung eignen sich etwa O-Ringe oder Quadringe. Um die Dichtung an geeigneter Stelle zu positionieren, können der Anordnung geeignete Fixiermittel hinzugefügt werden. So kann die Dichtung etwa durch eine verschraubte Platte fixiert werden. As a seal are about O-rings or quad rings. In order to position the gasket at a suitable location, suitable fixing means may be added to the assembly. For example, the seal can be fixed by a bolted plate.
In einer bevorzugten Weiterbildung umfasst die Anordnung auch ein Getriebegehäuse. Die erste Komponente und die zweite Komponente befinden sich innerhalb des Getriebegehäuses. Dies impliziert, dass sich auch der Spalt und damit das Trägermaterial mit den Partikeln innerhalb des Getriebegehäuses befinden. Die Dichtung verhindert, dass die Partikel aus dem Spalt heraus in das Getriebegehäuse gelangen und dort Schäden an Lagern oder Verzahnungen verursachen. In a preferred embodiment, the arrangement also includes a transmission housing. The first component and the second component are located within the transmission housing. This implies that the gap and thus the carrier material with the particles are also located inside the gear housing. The seal prevents the particles from entering the gearbox housing from the gap, causing damage to bearings or gears.
Bevorzugte Ausführungsbeispiele der Erfindung sind in den Figuren dargestellt. Übereinstimmende Bezugsziffern kennzeichnen dabei gleiche oder funktionsgleiche Merkmale. Im Einzelnen zeigt: Preferred embodiments of the invention are shown in the figures. Matching reference numbers identify identical or functionally identical characteristics. In detail shows:
Fig. 1 : eine erste Flanschverbindung; und Fig. 1: a first flange connection; and
Fig. 2: eine zweite Flanschverbindung.  Fig. 2: a second flange connection.
In den Figuren 1 und 2 sind ein erster Flansch 101 und ein zweiter Flansch 103 abgebildet. Zwischen dem ersten Flansch 101 und dem zweiten Flansch 103 verläuft ein Spalt 105. Entlang des Spalts 105 sind der erste Flansch 101 und der zweite Flansch 103 relativ zueinander verdrehbar. In Figures 1 and 2, a first flange 101 and a second flange 103 are shown. Between the first flange 101 and the second flange 103 extends a gap 105. Along the gap 105, the first flange 101 and the second flange 103 are rotatable relative to each other.
Um den ersten Flansch 101 und den zweiten Flansch 103 drehfest miteinander zu verbinden, ist eine Scheibe 107 in den Spalt 105 eingelegt. Die Scheibe 107 ist mit Diamantstaub beschichtet. Weiterhin sind der erste Flansch 101 und der zweite Flansch 103, etwa mittels Schrauben, gegen den Ring 107 verspannt. Dadurch drückt sich der Diamantstaub in den ersten Flansch 101 , in den zweiten Flansch 103 und in den Ring 107 ein. Zwischen den Partikeln des Diamantstaubs, dem ersten Flansch 101 , dem zweiten Flansch 103 und dem Ring 107 kommt somit eine formschlüssige Verbindung zustande. Diese ist stärker belastbar als kraftschlüssige Verbindungen herkömmlicher Flansche. In order to non-rotatably connect the first flange 101 and the second flange 103, a disk 107 is inserted into the gap 105. The disc 107 is coated with diamond dust. Furthermore, the first flange 101 and the second flange 103, for example by means of screws, clamped against the ring 107. As a result, the diamond dust presses into the first flange 101, into the second flange 103 and into the ring 107. Between the particles of the diamond dust, the first flange 101, the second flange 103 and the ring 107 thus comes about a positive connection. This is stronger than non-positive connections of conventional flanges.
Um zu verhindern, dass der Diamantstaub aus dem Spalt 105 austritt und umgebende Lager oder Verzahnungen beschädigt, weist die in Fig. 1 dargestellte Anordnung einen O-Ring 109 auf. Der O-Ring 109 ist so angeordnet, dass er den Spalt 105 abdichtet. In order to prevent the diamond dust from escaping from the gap 105 and damaging surrounding bearings or toothings, the arrangement shown in FIG. 1 has an O-ring 109. The O-ring 109 is arranged to seal the gap 105.
Die in Fig. 2 dargestellte Anordnung weist anstelle des O-Rings 109 eine Hülse 201 auf. Die Hülse 201 ist so auf den ersten Flansch 101 und den zweiten Flansch 103 aufgeschoben, dass sie den Spalt 105 abdeckt. Sie wird mittels eines Sprengrings 203 in Position gehalten. Zum Auffangen der gelösten Partikel bildet die Hülse 201 eine Kammer 203 aus. The arrangement shown in FIG. 2 has a sleeve 201 instead of the O-ring 109. The sleeve 201 is pushed onto the first flange 101 and the second flange 103 so as to cover the gap 105. It is held in position by means of a snap ring 203. To catch the dissolved particles, the sleeve 201 forms a chamber 203.
