Abstract
Description
Die Erfindung betrifft einen Schleifringübertrager zur Übertragung von elektrischen Strömen und/oder Signalen zwischen einem Stator und einem Rotor.The invention relates to a slip ring transmitter for the transmission of electrical Currents and / or signals between a stator and a rotor.
Bei Schleifringübertragern größeren Durchmessers ist es bekannt, die sogenannte Kohle/Kohle-Technik einzusetzen. Dies ist beispielsweise bei größeren Generatoren der Fall. Um hierbei in den umfangsseitig geschlossenen Schleifringen elektrische Kontakte festlegen zu können, müssen die Schleifringe große Wanddicken haben, damit auch ausreichend große Gewinde untergebracht werden können.In slip ring transmitters of larger diameter it is known, the so-called Use coal / coal technology. This is the case with larger ones, for example Generators the case. To do this in the circumferentially closed The slip rings must be able to define slip rings for electrical contacts have large wall thicknesses, so that threads are sufficiently large can be accommodated.
Mithin ist die Verwendung der Kohle/Kohle-Technik bei Schleifringübertragern mit kleinen Durchmessern und umfangsseitig geschlossenen Schleifringen nicht möglich.Therefore, the use of coal / coal technology in slip ring transmitters with small diameters and slip rings closed on the circumference not possible.
Um dennoch die Kohle/Kohle-Technik auch bei Schleifringübertragern kleineren Durchmessers anwenden zu können, hat man die Schleifringe in einzelne Segmente gegliedert und jedes Schleifringsegment auf einem entsprechenden Tragkörper, insbesondere aus Messing, durch Klebung festgelegt. To make the coal / coal technology smaller even with slip ring transmitters To be able to use diameter, you have the slip rings in individual Structured segments and each slip ring segment on a corresponding one Support body, especially made of brass, fixed by gluing.
Bei solchen Bauarten waren dann Spalte zwischen den in Umfangsrichtung aufeinander folgenden Schleifringsegmenten nicht zu vermeiden. Die Spalte führten zu elektrischen Störungen mit der Folge, dass die Übertragung von Signalen, insbesondere Messsignalen, mit Ungenauigkeiten verbunden war.In such designs there were gaps between those in the circumferential direction successive slip ring segments cannot be avoided. The gap led to electrical interference with the result that the transmission of Signals, especially measurement signals, was associated with inaccuracies.
Der Erfindung liegt - ausgehend vom Stand der Technik - die Aufgabe zugrunde, einen Schleifringübertrager zu schaffen, der auch bei einem kleinen Durchmesser in der Kohle/Kohle-Technik wirtschaftlich herstellbar ist und betrieben werden kann.The object of the invention is based on the prior art to create a slip ring transmitter that works even with a small Diameter in the coal / coal technology is economically producible and can be operated.
Diese Aufgabe wird mit den im Patentanspruch 1 angegebenen Merkmalen gelöst.This object is achieved with the features specified in claim 1 solved.
Danach wird jetzt ein umfangseitig geschlossener Innenring aus einem Nichteisenmetall, insbesondere aus Messing, in eine Isoliermasse als Bestandteil eines Rotors eingebettet. Die Isoliermasse kann zum Beispiel Epoxydharz sein. Der Innenring wird mit einem dem Rotor zugeordneten elektrischen Anschluss elektrisch kontaktiert und von hier aus mit einer stirnseitigen Kabelverschraubung verbunden.Then an inner ring closed on the circumference is now made from one Non-ferrous metal, especially brass, in an insulating compound as a component embedded in a rotor. The insulating compound can, for example Be epoxy resin. The inner ring is assigned to the rotor electrical connection electrically contacted and from here with an end Cable gland connected.
Umfangsseitig des Innenrings erstreckt sich ein umfangseitig ebenfalls geschlossener Außenring aus Graphit. Dieser Außenring ist seitlich so durch Isoliermassen fixiert, dass er zum Innenring einwandfrei konzentrisch zentriert ist. Hierbei wird zwischen den Innenring und dem Außenring gezielt ein Spalt ausgebildet, welcher bei Wärmeeinwirkung den unterschiedlichen Ausdehnungskoeffizienten von z.B. Messing und Graphit Rechnung trägt. Hierbei ist die Temperaturspanne zwischen der Umgebungstemperatur bis maximal zulässiger Betriebstemperatur zu berücksichtigen.On the circumferential side of the inner ring, a circumferentially closed one also extends Graphite outer ring. This outer ring is laterally through Insulating materials fixed that it is perfectly concentric with the inner ring is centered. Here is targeted between the inner ring and the outer ring a gap is formed, which the different when exposed to heat Expansion coefficients of e.g. Takes account of brass and graphite. The temperature range between the ambient temperature is up to the maximum permissible operating temperature.
Um ständig eine einwandfreie elektrische Kopplung zwischen dem Innenring und dem Außenring unter Überbrückung des Spalts herzustellen, sind umfangsseitig des Innenrings metallische Kontaktlamellen vorgesehen, die über den gesamten Umfang des Innenrings oder nur über Teilbereiche angeordnet sein können. Diese Kontaktlamellen sind so gestaltet, dass sie in sich selbst federnd sind und auf diese Weise den Änderungen in der Spaltgröße zwischen Innenring und Außenring aufgrund Wärmeeinwirkungen ohne weiteres folgen können und ständig die elektrische Kopplung zwischen Innenring und Außenring herstellen.To keep a perfect electrical coupling between the inner ring and to manufacture the outer ring by bridging the gap are circumferential of the inner ring provided metallic contact lamellae, which arranged the entire circumference of the inner ring or only over partial areas could be. These contact blades are designed so that they are in themselves themselves are resilient and in this way the changes in gap size between inner ring and outer ring due to heat effects without more can follow and constantly the electrical coupling between the inner ring and produce the outer ring.
Die Kontaktlamellen können z.B. aus einer Kupfer-Beryllium-Legierung hergestellt und dann wärmetechnisch behandelt sein.The contact blades can e.g. made from a copper-beryllium alloy and then be thermally treated.
Die Erfindung ist mit dem besonderen Vorteil verbunden, dass der Außenring aus Graphit nicht nur in der Wanddicke, sondern auch im Durchmesser klein gehalten werden kann. Auf diese Weise ist es möglich, kompakte Schleifringübertrager mit Außendurchmessern von 200mm und kleiner bereit zu stellen, die neben Signalen, insbesondere Messsignalen, auch elektrische Ströme bis zu etwa 50 Ampere übertragen können.The invention is associated with the particular advantage that the outer ring made of graphite not only small in wall thickness, but also small in diameter can be held. In this way it is possible to be compact Slip ring transmitters with outer diameters of 200mm and smaller ready to provide, in addition to signals, especially measurement signals, also electrical Currents up to about 50 amps can be transmitted.
Darüber hinaus gewährleistet die Erfindung, dass jetzt Geschwindigkeiten bis zu etwa 60 m/s erreichbar sind.In addition, the invention ensures that now speeds up can be reached at about 60 m / s.
Ferner wird mit der Erfindung erreicht, dass der Schleifkontakt nur mit einer vergleichsweise geringen Kraft an den Außenring gepresst werden muss, um eine einwandfreie Signal- und/oder Stromübertragung zu gewährleisten. Ein geringer Anpressdruck führt zu einem deutlich geringeren Verschleiss und letztlich zu einer längeren Standzeit eines Schleifringübertragers. Außerdem ist der Abrieb sehr gering, so dass innerhalb des Schleifringübertragers im Prinzip keine Verschmutzung eintreten kann und demzufolge auch keine durch eine abriebbedingte Verschmutzung hervorgerufenen elektrischen Kurzschlüsse entstehen können.It is also achieved with the invention that the sliding contact with only one comparatively small force must be pressed against the outer ring to ensure proper signal and / or power transmission. On low contact pressure leads to significantly less wear and tear ultimately to a longer service life of a slip ring transmitter. Moreover the abrasion is very low, so that inside the slip ring In principle, no pollution can occur and therefore no pollution electrical caused by abrasion-related contamination Short circuits can occur.
Um den Kontaktlamellen einen sicheren Halt am Innenring zu geben, ist gemäß
Patentanspruch 2 in die äußere Oberfläche des Innenrings eine Umfangsnut
eingearbeitet. In diese Umfangsnut werden nun die Kontaktlamellen
über den ganzen Umfang verteilt oder nur abschnittsweise eingebettet. Da
die Kontaktlamellen einen mittleren bombierten Abschnitt aufweisen, liegt
dieser Abschnitt unabhängig von der Größe des Spalts zwischen Innenring
und Außenring ständig an der inneren Oberfläche des Außenrings.In order to give the contact lamella a secure hold on the inner ring, according to
Die Festlegung der Kontaktlamellen in der Umfangsnute erfolgt insbesondere durch Klemmung über seitlich der Bombierung befindliche Stege.In particular, the contact lamellae are defined in the circumferential groove by clamping over bars located on the side of the crown.
Ein einwandfreier Korrosionsschutz der Kontaktlamellen wird entsprechend
Patentanspruch 3 dadurch erzielt, dass die neben den Kontaktlamellen liegenden
Bereiche der äußeren Oberfläche des Innenrings vergoldet sind.Correct corrosion protection of the contact lamellae is accordingly
Auch die Maßnahme des Patentanspruchs 4 trägt mit dazu bei, dass eine einwandfreie Strom- und Signalübertragung gewährleistet werden kann, ohne dass hohe Anpressdrücke des Schleifkontakts an den Außenring erforderlich wären.The measure of claim 4 also contributes to the fact that a perfect power and signal transmission can be guaranteed, without the need for high contact pressure of the sliding contact on the outer ring would.
Eine besonders vorteilhafte Ausführungsform der Erfindung wird in den
Merkmalen des Patentanspruchs 5 erblickt. Eine solche Ausführungsform
besitzt in der Regel mehrere mit Abstand einander koaxial zugeordnete Innenringe
und Außenringe sowie den Außenringen zugeordnete Schleifkontakte.
Die Innenringe sind hierbei in eine Isoliermasse in Form einer Isolierbuchse
eingegossen. Die Außenringe sind durch Isoliermassen in Form von
Isolierringen zueinander distanziert. An jeden Außenring sind zwei Schleifkontakte
gedrückt, die an den Enden von Schwenkarmen befestigt sind. Die
Schwenkarme weisen hierbei in entgegengesetzte Richtungen. Um eine axial
kompakte Bauart zu verwirklichen, sind die jedem Außenring zugeordneten
Schwenkarme zum jeweils benachbarten Außenring in Umfangsrichtung
versetzt angeordnet. Ein gegenseitiger störender Einfluss wird auf diese
Weise vermieden.A particularly advantageous embodiment of the invention is in the
Features of
Jeder Innenring ist über in die Isolierbuchse eingebettete elektrische Verbindungsleitungen zu einem Kontaktanschluss an einem Ende der Isolierbuchse geführt. Von diesem Kontaktanschluss führen dann Leitungen zu einer stirnseitigen Kabelverschraubung am Rotor.Each inner ring is via electrical connection lines embedded in the insulating bush to a contact connection at one end of the insulating bush guided. Lines then lead from this contact connection to one front cable gland on the rotor.

den Enden der Isolierbuchse. Dazu ist ein Längenabschnitt der Hohlwelle,
welche aus Stahl oder aus einem anderen Material bestehen kann, im etwa
mittleren Längenbereich der Isolierbuchse umfangsseitig mit einem kleineren
Durchmesser versehen. Die Außenringe und die Isolierringe sind von einem
Stirnende der Isolierbuchse her nacheinander auf die Innenringe bzw. die
Isolierbuchse geschoben. Dazu weist die Isolierbuchse an einem Ende einen
umfangseitigen Kragen auf. Am anderen Ende wird eine Scheibe gegen den
letzten Isolierring verspannt, so dass dann alle Außenringe und Isolierringe
sicher lagefixiert sind. Die Hohlwelle kann über endseitige Wälzlager in
Stirnwänden des Stators gelagert sein.According to the features of
Die jedem Außenring zugeordneten Schwenkarme sind jeweils an eine Halterung angelenkt. Diese Halterung ist auf einer sich parallel zur Drehachse des Rotors erstreckenden, im Stator fixierten Tragstange durch Klemmung festgelegt. Die Tragstange kann beispielsweise in den Stirnwänden des Stators festgelegt sein. Die aufeinander folgenden Halterungen sind durch die Tragstange umgebende Distanzhülsen lagebestimmt.The swivel arms assigned to each outer ring are each attached to a holder hinged. This bracket is on a parallel to the axis of rotation of the rotor extending, fixed in the stator support rod by clamping established. The support rod can, for example, in the end walls of the Stator. The successive brackets are through the spacer sleeves surrounding the support rod are positioned.
