Description

Technisches GebietTechnical area

Die Erfindung betrifft eine Schleifringanordnung zur Übertragung elektrischer Signale mittels Schleifkontakten zwischen gegeneinander drehbaren Teilen. Auf einer Schleifbahn aus elektrisch leitfähigem Material schleift wenigstens ein Schleifkontakt, auch Bürste genannt, aus einem ebenfalls elektrisch leitfähigen Material. Durch den galvanischen Kontakt zwischen Schleifbahnen und Kontakt kann elektrischer Strom übertragen werden.The invention relates to a slip ring assembly for transmitting electrical signals by means of sliding contacts between mutually rotatable parts. On a sliding track made of electrically conductive material, at least one sliding contact, also called a brush, grinds from a likewise electrically conductive material. Due to the galvanic contact between the sliding tracks and contact electrical current can be transmitted.

Stand der TechnikState of the art

Die EP 0 662 736 A offenbart eine Schleifringanordnung, bei der eine Bürste mit mehreren Drähten in einer V-Nut läuft. Dadurch ergibt sich durch die Parallelschaltung mehrerer Kontakte ein niedriger Übergangswiderstand.The EP 0 662 736 A discloses a slip ring assembly in which a multi-wire brush runs in a V-groove. This results in the parallel connection of several contacts a low contact resistance.

In der DE 14 89 080 A ist eine Schleifring Anordnung offenbart, bei der Bürsten in Form von massiven Einzeldrähten in Nuten einer Schleifbahn laufen.In the DE 14 89 080 A discloses a slip ring assembly in which brushes in the form of solid strands run in grooves of a slideway.

In der US 4,398,113 ist eine weitere Bürste mit mehreren Drähten offenbart. Hierbei weist die Schleifbahn eine geringere Härte als die Bürste auf, so dass sich beim initialen Einlaufen der Bürste weiches Gold von der Schleifbahn an der Bürste anlagert. Dies führt zu einer lang anhaltenden und reibungsarmen Beschichtung an der Bürste.In the US 4,398,113 Another brush with multiple wires is revealed. In this case, the grinding path has a lower hardness than the brush, so that at the initial run-in of the brush soft gold from the grinding path to the brush attaches. This leads to a long-lasting and low-friction coating on the brush.

In der DE 34 34 627 A1 ist eine Schleifkontaktanordnung offenbart, bei der unter einer leitfähigen Kontaktschicht eine harte, amorphe Zwischenschicht angeordnet ist. Diese amorphe Zwischenschicht stützt die Kontaktschicht und sorgt somit dafür, dass diese eine hohe Lebensdauer bei geringem Abrieb erhält.In the DE 34 34 627 A1 discloses a sliding contact arrangement in which a hard, amorphous intermediate layer is arranged under a conductive contact layer is. This amorphous interlayer supports the contact layer, thus ensuring that it has a long service life with low abrasion.

Um gute Übertragungseigenschaften zu erreichen, sind die Kontaktpaarungen, d.h. die äußeren Metallschichten der Bürsten und der Schleifbahnen aus elektrisch gut leitfähigen und abriebfesten Materialien hergestellt. Bevorzugt werden auf Gold basierende Schichten eingesetzt. Dennoch kommt es nach längeren Betriebszeiten oftmals zu einem Verschleiß von Bürsten und/oder Schleifbahnen. Ist die Goldschicht einer Schleifbahn beschädigt, so läuft die Bürste auf der unter dieser liegenden Schicht, welche beispielsweise Nickel oder ein anderes ähnliches Metall umfasst. Es kommt hier sofort zu massiven Kontaktstörungen und zu einem starken Abrieb der Bürste. In einem solchen Fehlerfall ist oftmals nur ein kompletter Ersatz von Bürste und Schleifbahn notwendig.To achieve good transmission properties, the contact pairings, i. the outer metal layers of the brushes and the sliding tracks made of electrically highly conductive and abrasion resistant materials. Preference is given to using gold-based layers. Nevertheless, it often comes after longer periods of operation to a wear of brushes and / or slideways. If the gold layer of a grinding path is damaged, the brush runs on the underlying layer, which for example comprises nickel or another similar metal. It comes here immediately to massive contact disturbances and a strong abrasion of the brush. In such an error case often only a complete replacement of brush and sanding path is necessary.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, die Lebensdauer von Schleifringsystemen zu erhöhen, Schleifringsysteme mit Notlaufeigenschaften zu versehen und eine frühzeitige Verschleißanzeige zu ermöglichen.The invention has for its object to increase the life of slip ring systems to provide slip ring systems with emergency running properties and to allow early wear indicator.

Diese Aufgabe wird durch eine Vorrichtung nach Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by a device according to claim 1. Advantageous embodiments of the invention are specified in the subclaims.

Die Erfindung basiert auf der Kombination unterschiedlicher Kontaktmaterialien mit unterschiedlichen Abriebeigenschaften. Die Bürste, die einen oder mehrere Drähte umfassen kann, hat an ihrer Oberfläche, d.h. an der Oberfläche des einen oder der mehreren Drähte ein erstes elektrisch gut leitfähiges Kontaktmaterial. Die Bürste kann auch vollständig aus diesem ersten Kontaktmaterial bestehen. Die Bürste liegt auf einer entsprechenden Schleifbahn auf und kann bei Bewegung auf dieser entlang schleifen.The invention is based on the combination of different contact materials with different Abriebeigenschaften. The brush, which may comprise one or more wires, has on its surface, ie on the surface of the one or more wires, a first electrically highly conductive contact material. The brush may also consist entirely of this first contact material. The brush rests on a corresponding sliding track and can grind along it when moving.

Die Schleifbahn umfasst wenigstens eine obere Schicht mit einem zweiten elektrisch gut leitfähigen Kontaktmaterial. Unter dieser oberen Schicht ist eine untere Schicht mit einem dritten elektrisch gut leitfähigen Kontaktmaterial angeordnet. Die Schichten aus dem zweiten und dritten Kontaktmaterial weisen im Kontakt mit dem ersten Kontaktmaterial ähnlich gute Eigenschaften auf und besitzen einen geringen Übergangswiderstand. Unter dieser Schicht können sich noch weitere Schichten, wie beispielsweise auf Nickel und/oder auf Kupfer basierende Schichten befinden. Bevorzugt werden diese Schichten galvanisch aufgebracht.The slideway comprises at least one upper layer with a second electrically highly conductive contact material. Under this upper layer, a lower layer is arranged with a third electrically good conductive contact material. The layers of the second and third contact material have similar good properties in contact with the first contact material and have a low contact resistance. Under this layer may be further layers, such as nickel and / or copper based layers. These layers are preferably applied by electroplating.

Erfindungsgemäß weisen diese Schichten im Schleifkontakt zueinander bestimmte Eigenschaften auf. So ist beim Kontakt der Bürste umfassend das erste Kontaktmaterial mit der oberen Schicht umfassend das zweite Kontaktmaterial der Abrieb des zweiten Kontaktmaterials größer als der des ersten Kontaktmaterials. Somit verschleißt die obere Schicht der Schleifbahn umfassend das zweite Kontaktmaterial schneller als die Bürste umfassend das erste Kontaktmaterial. Weiterhin ist beim Kontakt der Bürste umfassend das erste Kontaktmaterial mit der unteren Schicht umfassend das dritte Kontaktmaterial der Abrieb des dritten Kontaktmaterials kleiner als der des ersten Kontaktmaterials.According to the invention, these layers have sliding properties relative to each other. Thus, upon contact of the brush comprising the first contact material with the upper layer comprising the second contact material, the abrasion of the second contact material is greater than that of the first contact material. Thus, the upper layer of the abrasive web comprising the second contact material wears faster than the brush comprising the first contact material. Furthermore, upon contact of the brush comprising the first contact material with the lower layer comprising the third contact material, the abrasion of the third contact material is smaller than that of the first contact material.

Aus dieser Konfiguration verläuft der Abrieb ausgehend von einer neuen Bürste mit einer neuen Schleifbahn wie folgt: zunächst verschleißt das zweite Kontaktmaterial der oberen Schicht, was der normalen Lebensdauer eines Schleifringsystems entspricht. Nachdem die Schicht des zweiten Kontaktmaterials aufgebraucht ist, macht die Bürste mit dem dritten Kontaktmaterial der unteren Schicht Kontakt. Übertragungseigenschaften des Schleifrings bleiben hierbei erhalten, da das dritte Kontaktmaterial ebenfalls gute elektrische Leitfähigkeit und gute Kontakteigenschaften besitzt. Dadurch können Notlaufeigenschaften bzw. eine deutliche Verlängerung der Lebensdauer erreicht werden. Dieses dritte Kontaktmaterial der Schleifbahn ist wie bereits zuvor beschrieben, abriebfester als das erste Kontaktmaterial der Bürste. Somit verschleißt nun die Bürste schneller als die Schleifbahn. Bei der Wartung der Schleifringanordnung ist ein Verschleiß der Bürste an deren unebener Oberfläche relativ leicht zu erkennen. In diesem Fall ist bei einer verschlissenen Bürste auch die Schleifbahn auszutauschen. Da in diesem Falle die Goldschicht auf der Schleifbahn noch nicht vollständig abgetragen ist, kann die Schleifbahn bzw. ein Modul, welches mehrere Schleifbahnen trägt, nun auf einfache Weise galvanisch wieder in Stand gesetzt werden. Dies ist nicht möglich bei dem Stand der Technik entsprechenden Modulen, bei denen die Goldschicht bis auf die Unterschicht abgetragen ist.From this configuration, the abrasion proceeds from a new brush with a new sanding path as follows: first, the second upper layer contact material wears out, which is the normal life of a slip ring system. After the layer of the second contact material is used up, the brush makes contact with the third contact material of the lower layer. Transmission properties of the slip ring remain in this case, since the third contact material also has good electrical conductivity and good contact properties. As a result, emergency running properties or a significant extension of the service life can be achieved. This third contact material of the grinding path is, as already described above, more resistant to abrasion than the first contact material of the brush. Thus, the brush now wears faster than the grinding path. During maintenance of the slip ring assembly, wear of the brush on its uneven surface is relatively easy to detect. In this case, replace the grinding path with a worn brush. Since in this case the gold layer on the slideway is not completely removed, the slideway or a module which carries a plurality of slideways can now be galvanically restored in a simple manner. This is not possible in the prior art modules in which the gold layer is removed down to the lower layer.

Wesentlich für die Erfindung sind die Abriebeigenschaften der Kontaktmaterialien. Insbesondere bei Schleifringsystemen tritt ein adhäsiver Verschleiß (Kaltverschweißungen) auf. Dabei bilden sich die Kaltverschweißungen häufig auf dem härteren Material aus und das weichere Material erfährt einen Materialverlust die Härte ist ein Kennwert, der eine erste Aussage über das Verhalten ermöglicht. Allerdings kann je nach verwendetem Materialsystem speziell bei geringen Härteunterschieden, ein Verhalten auftreten, bei dem sich die Kaltverschweißungen auch auf dem weicheren Material bilden. Daher wird bei neuen unbekannten Materialpaarungen ein Komponententest durchgeführt, in dem das Verschleißverhalten sicher erkannt werden kann.Essential for the invention are the Abriebeigenschaften the contact materials. Especially with slip ring systems, adhesive wear (cold welding) occurs. In this case, the cold welds often form on the harder material and the softer material undergoes a loss of material hardness is a characteristic value that allows a first statement about the behavior. However, depending on the material system used, especially at low hardness differences, a behavior may occur in which the cold welds also form on the softer material. Therefore, in new unknown material pairings, a component test is carried out in which the wear behavior can be reliably detected.

Besonders bevorzugt weist die obere Schicht der Schleifbahn mit dem zweiten Kontaktmaterial eine Härte kleiner als die der beiden anderen Kontaktmaterialien auf. Die Bürste mit dem ersten Kontaktmaterial hat bevorzugt eine größere Härte als die obere Schicht der Schleifbahn mit dem zweiten Kontaktmaterial und eine kleinere Härte als die untere Schicht der Schleifbahn mit dem dritten Kontaktmaterial. Weiterhin hat bevorzugt die untere Schicht der Schleifbahn mit dem dritten Kontaktmaterial eine Härte größer als die beiden anderen Kontaktmaterialien. Durch die härtere untere Schicht ergibt sich ein stabiler Schichtaufbau. Unter dem Begriff der Härte wird hier die Härte nach Rockwell oder Brinell oder Vickers verstanden.Particularly preferably, the upper layer of the grinding path with the second contact material has a hardness smaller than that of the other two contact materials. The brush with the first contact material preferably has a greater hardness than the upper layer of the grinding path with the second contact material and a lower hardness than the lower layer of the grinding path with the third contact material. Furthermore, the lower layer of the grinding path with the third contact material preferably has a hardness greater than the other two contact materials. The harder lower layer results in a stable layer structure. The term hardness is understood to mean the hardness of Rockwell or Brinell or Vickers.

Es ist weiterhin besonders bevorzugt, wenn die untere Schicht der Schleifbahn eine relativ glatte Oberfläche, insbesondere mit einer Rauhtiefe kleiner 1 µm und besonders bevorzugt kleiner 0.1 µm aufweist. Dadurch kann ein besonders abriebarmes Gleiten der Bürste auf dieser Schicht realisiert werden.It is furthermore particularly preferred if the lower layer of the grinding path has a relatively smooth surface, in particular with a roughness depth of less than 1 μm and particularly preferably less than 0.1 μm. As a result, a particularly abrasion-free sliding of the brush on this layer can be realized.

Besonders vorteilhaft ist es, wenn die Bürste massiv aus dem ersten Kontaktmaterial ausgeführt ist. Es steht dann besonders viel Material zum Abrieb zur Verfügung, so dass sich eine verlängerte Lebensdauer ergibt.It is particularly advantageous if the brush is made of solid material from the first contact material. There is then a lot of material available for abrasion, so that there is an extended life.

In einer vorteilhaften Weiterbildung der Erfindung weist die Bürste unter der Schicht mit dem ersten Kontaktmaterial eine weitere Schicht mit einem vierten Kontaktmaterial auf. Das vierte Kontaktmaterial ist bevorzugt härter als das erste Kontaktmaterial und besonders bevorzugt härter als das dritte Kontaktmaterial. Hierdurch kann die Lebensdauer des Schleifrings weiter verlängert werden Beispielhaft hat das erste Kontaktmaterial der Bürste eine Härte im Bereich von HV 270-350. Weiterhin kann beispielhaft die Härte des zweiten Kontaktmaterials der Schleifbahn in einem Bereich von HV 180-220 liegen. Schließlich kann der Bereich der Härte des dritten Kontaktmaterials der Schleifbahn in einem Bereich von HV 350-420 liegen.In an advantageous development of the invention, the brush has a further layer with a fourth contact material under the layer with the first contact material. The fourth contact material is preferably harder than the first contact material, and more preferably harder than the third contact material. As a result, the life of the slip ring can be further extended. By way of example, the first contact material of the brush has a hardness in the range of HV 270-350. Furthermore, by way of example, the hardness of the second contact material of the grinding path may be in the range of HV 180-220. Finally, the range of hardness of the third contact material of the grinding path may be in a range of HV 350-420.

Der Begriff der Kontaktmaterialien bezieht sich hier immer auf Materialien, die in mechanischem Kontakt mit einem weiteren Kontaktmaterial zur Übertragung elektrischer Signale geeignet sind. Kontaktmaterialien haben bevorzugt geringe Übergangswiderstände und zum Einsatz in Schleifringen niedriges Kontaktrauschen bei mechanischer Bewegung. Kontaktmaterialien sind beispielsweise Gold und/oder Silber sowie Legierungen daraus. Keine Kontaktmaterialien sind beispielsweise Stahl, welcher aufgrund seiner Federeigenschaften als Kern einer Bürste eingesetzt werden kann, wenn dieser mit einem Kontaktmaterial beschichtet ist, oder auch Nickel, welches im galvanischen Schichtaufbau von Schleifringen unterhalb einer Schicht aus Kontaktmaterial eingesetzt wird.The term contact materials here always refers to materials which are suitable in mechanical contact with another contact material for the transmission of electrical signals. Contact materials preferably have low contact resistance and, for use in slip rings, low contact noise during mechanical movement. Contact materials are, for example, gold and / or silver and alloys thereof. No contact materials are, for example, steel, which due to its spring properties as the core of a Brush can be used when it is coated with a contact material, or nickel, which is used in the galvanic layer structure of slip rings below a layer of contact material.

Ein weiterer Aspekt der Erfindung ist ein Verfahren zur Herstellung von einer Schleifbahn für den Schleifkontakt mit einer Bürste. Hierbei hat die Bürste ein erstes Kontaktmaterial an der Oberfläche.Another aspect of the invention is a method of making a sanding pad for brushing with a brush. Here, the brush has a first contact material on the surface.

Das Verfahren umfasst die folgenden Schritte:

  • Beschichtung der Schleifbahn mit einem dritten Kontaktmaterial, welches im Kontakt mit der Bürste einen geringeren Abrieb als die Bürste aufweist;
  • Beschichtung der Schleifbahn mit einem zweiten Kontaktmaterial, welches im Kontakt mit der Bürste einen höheren Abrieb als die Bürste aufweist.
The method comprises the following steps:
  • Coating the slideway with a third contact material, which has less abrasion than the brush in contact with the brush;
  • Coating the grinding path with a second contact material, which has a higher abrasion than the brush in contact with the brush.

Mit diesem Verfahren sind alle zuvor beschrieben Varianten und Ausführungsbeispiele kombinierbar.All previously described variants and exemplary embodiments can be combined with this method.

  • FIG. 2 shows a slip ring assembly in general form
  • FIG. 3 shows different levels of abrasion
  • FIG. 4 shows a brush with visible wear

In Figur 1 ist eine erfindungsgemäße Vorrichtung dargestellt. Der Bürste 10 hat eine Schicht 11 aus einem ersten Kontaktmaterial. Alternativ hierzu kann die Bürste auch vollständig aus diesem ersten Kontaktmaterial bestehen. Sie läuft in einer V-förmigen Nut der Schleifbahn 30 und liegt an den Auflagepunkten 50, 51 an der Schleifbahn an. Die Schleifbahn 30 hat eine untere Schicht 32 mit einem dritten Kontaktmaterial sowie eine obere Schicht 31 mit einem zweiten Kontaktmaterial. Die Schichten der Kontaktmaterialien sind in diesen Figuren deutlich vergrößert dargestellt, um die Zeichnungen anschaulich zu machen. Tatsächlich sind typische Schichtdicken im Bereich von ca. 3 µm bis 5 µm.In FIG. 1 a device according to the invention is shown. The brush 10 has a layer 11 of a first contact material. Alternatively, the brush may also consist entirely of this first contact material. It runs in a V-shaped groove of the grinding path 30 and abuts against the support points 50, 51 on the grinding path. The grinding path 30 has a lower layer 32 with a third contact material and an upper layer 31 with a second contact material. The layers of the contact materials are shown clearly enlarged in these figures in order to illustrate the drawings. In fact, typical layer thicknesses are in the range of about 3 microns to 5 microns.

In Figur 2 ist ein Schleifringanordnung in allgemeiner Form dargestellt. Auf einer Schleifbahn 30 läuft wenigstens eine Bürste 10, welche von einem Bürstenträger 20 gehalten wird.In FIG. 2 a slip ring assembly is shown in general form. On a grinding path 30 at least one brush 10, which is held by a brush holder 20 runs.

In Figur 3 verschiedene Stufen des Antriebs dargestellt. Hierzu zeigt die Figur 3a den Neuzustand mit vollständig ausgebildeten und nicht abgeschriebenen Schichten aus Kontaktmaterialien 11, 31,32. Die Figur 3b zeigt eine verschlissene obere Schicht 31 mit zweitem Kontaktmaterial der Schleifbahn. Hier ist noch die Schicht 11 mit erstem Kontaktmaterial der Bürste ohne Verschleißerscheinungen. Durch weitere Benutzung des Schleifring Verschleißt nun auch diese Schicht, so dass sich der in Figur 3c dargestellte Zustand einstellt. Für den Fall, dass die Bürste einen Kern aus einem Nicht-Kontaktmaterial, wie beispielsweise Stahl aufweist, ist nun die Verschleißgrenze erreicht. Sollte die Bürste massiv aus dem ersten Kontaktmaterial bestehen, so kann diese weiter benutzt werden.In FIG. 3 represented different stages of the drive. This shows the FIG. 3a the new condition with fully formed and not written off layers of contact materials 11, 31,32. The FIG. 3b shows a worn upper layer 31 with second contact material of the grinding path. Here is the layer 11 with the first contact material of the brush without signs of wear. By further use of the slip ring now also wear this layer, so that in Figure 3c shown state. In the event that the brush has a core of a non-contact material, such as steel, the wear limit has now been reached. If the brush is made of the first contact material, then it can continue to be used.

Figur 4 zeigt in seitlicher Ansicht eine Bürste 10 mit verschlissenem Kontaktmaterial. Hier ist an der Position 12 durch das Schleifen an der Schleifbahn ein Materialdefekt entstanden. Dieser kann zur Verschleißanzeige herangezogen werden. Solange die Bürste ohne Defekte im Material ist, wird offensichtlich noch die obere Schicht 31 mit dem zweitem Kontaktmaterial der Schleifbahn abgetragen und eine Verschleißgrenze ist noch nicht erreicht. Erst wenn Materialdefekte an der Bürste auftreten, schleift diese in der unteren Schicht 32 der Schleifbahn. In diesem Zustand sollte nun ein Austausch oder eine Erneuerung der Schleifbahn erfolgen. FIG. 4 shows a side view of a brush 10 with worn contact material. At position 12, a material defect has been created by grinding on the grinding path. This can be used for wear indication. As long as the brush is without defects in the material, obviously the top layer 31 is removed with the second contact material of the grinding path and a wear limit has not yet been reached. Only when material defects on the brush occur, this rubs in the lower layer 32 of the grinding path. In this state, an exchange or a renewal of the slideway should now take place.
