Description
Die Erfindung betrifft eine HF-Drehkupplung, bestehend aus einer feststehenden und einer in dieser gelagerten drehbaren Baugruppe, mit einer ersten Koaxialleitung, deren Mittelachse gleich der Drehachse der Drehkupplung ist, mit einer zweiten Koaxialleitung in Form eines Leitungsabschnitts, der als Innenleiter den Außenleiter der ersten Koaxialleitung hat und dessen Enden in der feststehenden und der drehbaren Baugruppe als Übergänge auf je einen Hohlleiter ausgebildet sind, wobei die Innen- und die Außenleiter der ersten und der zweiten Koaxialleitung zwischen der feststehenden und der drehbaren Baugruppe berührungslos über λ/4-Chokes HF-mäßig verbunden sind.The invention relates to an HF rotary coupling consisting of one fixed and one rotatable in it Assembly, with a first coaxial line, the central axis is equal to the axis of rotation of the rotary coupling, with a second coaxial line in the form of a line section, the the inner conductor is the outer conductor of the first coaxial line has and the ends in the fixed and the rotatable Module designed as transitions to a waveguide are, the inner and outer conductors of the first and the second coaxial line between the fixed and the rotatable assembly without contact via λ / 4-chokes HF-like are connected.
Eine Drehkupplung dieser Gattung ist aus einem 1992 verbreiteten Prospekt der Firma SIVERS IMA, Seiten 10A und 11A, bekannt. Dabei handelt es sich um eine Zweikanal-Drehkupplung. Jeder der beiden Kanäle kann auf einer oder auch mehreren Frequenzbändern betrieben werden. In der Regel dienen derartige HF-Drehkupplungen zur Verbindung von Radar- oder Kommunikations-Sender/Empfängern mit rotierenden oder zumindest schwenkenden Antennen. Über die Kanäle können - frequenzabhängig - Dauerstrichleistungen bis zu einigen 10 KW und Pulsleistungen bis in den Megawattbereich übertragen werden.A swivel coupling of this type is from a widespread 1992 SIVERS IMA brochure, pages 10A and 11A, known. It is a two-channel rotary coupling. Each of the two channels can be on one or also several frequency bands can be operated. Usually such RF rotary couplings are used to connect radar or Communication transmitter / receiver with rotating or at least waving antennas. Via the channels - frequency-dependent - continuous wave power up to a few 10 KW and pulse power transmitted into the megawatt range become.
Der Erfindung liegt die Aufgabe zugrunde, eine HF-Drehkupplung der eingangs genannte Gattung mit mindestens einem dritten HF-Kanal zu versehen.The invention has for its object an HF rotary coupling the genus mentioned at the beginning with at least one to provide the third RF channel.
Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß mindestens eine dritte, flexible Koaxialleitung als Kabel in einem die Dreh-achse der Drehkupplung wendelförmig umgebenden, in dem Man-tel der feststehenden Baugruppe ausgebildeten Kanal etwa rechteckigen Querschnitts angeordnet ist, und daß die Länge des Koaxialkabels so bemessen ist, daß in einer vorgegebenen Stellung der beweglichen Baugruppe zu der feststehenden Bau-gruppe die Windungen des Koaxialkabels etwa auf der halben Tiefe des Kanals schweben.This object is achieved in that at least a third, flexible coaxial line as a cable in a helically surrounding the rotary axis of the rotary coupling, trained in the jacket of the fixed assembly Channel is arranged approximately rectangular cross-section, and that the length of the coaxial cable is such that in a predetermined position of the movable assembly to the fixed assembly the coils of the coaxial cable hover about halfway down the canal.
Diese Lösung schränkt zwar den Drehwinkel der drehbaren Baugruppe, ausgehend von einer definierten Stellung gegenüber der feststehenden Baugruppe, auf z.B. ± 360° ein, hat aber den Vorteil, ohne nennenswerte Vergrößerung des häufig durch die Einbausituation begrenzten Durchmessers der Drehkupplung mindestens einen dritten HF-Kanal bereitzustellen. Dabei sorgt der wendelförmige Kanal in dem Mantel der feststehenden Bau-gruppe dafür, daß sich die Windungen der z.B. dritten, flexiblen Koaxialleitung nicht während der mit wechselndem Drehsinn erfolgenden Bewegungen der drehbaren Baugruppe übereinanderlegen können. Die Eigenelastizität der flexiblen Koaxialleitung stellt sicher, daß diese sich in der Nullstellung der Drehkupplung jeweils wieder auf etwa die halbe Tiefe des wendelförmigen Kanals einstellt. Im Bedarfsfall kann in den Kanal z.B. ein weiteres Koaxialkabel eingelegt und so ein vierter HF-Kanal bereitgestellt werden. Die beiden Kabel können z.B. durch einen radialen Trennsteg getrennt oder nach Art eines Kabelbaums miteinander verbunden werden, damit wie ihre notwendige Bewegungsfreiheit im Zuge der schwenkenden Drehbewegungen der drehbaren Baugruppe behalten.This solution limits the angle of rotation of the rotatable Assembly, starting from a defined position opposite the fixed assembly, e.g. ± 360 ° on but the advantage of not increasing the size significantly due to the installation situation of limited diameter of the rotary coupling to provide at least a third RF channel. The helical channel in the jacket of the fixed one Construction group that the turns of e.g. third, flexible coaxial line is not during the alternating directions of rotation of the rotatable Able to stack the assembly. The inherent elasticity of the Flexible coaxial line ensures that this is in the zero position of the rotary coupling again to about sets half the depth of the helical channel. in the If necessary, can be e.g. another coaxial cable inserted and a fourth RF channel is thus provided. The two cables can e.g. through a radial separator separately or connected in the manner of a wiring harness so as their necessary freedom of movement in the course of the pivoting rotary movements of the rotatable assembly to keep.
Abhängig von dem vorgegebenen, maximalen Drehwinkel kann die radiale Tiefe des wendelförmigen Kanals mindestens etwa das Doppelte des Durchmessers des Koaxialkabels betragen (Anspruch 2).Depending on the specified maximum angle of rotation, the radial depth of the helical channel at least about that Double the diameter of the coaxial cable (claim 2).
Die dritte Koaxialleitung ist ohne Zerlegung der Drehkupplung demontierbar, wenn das diese dritte Koaxialleitung bildende Kabel an beiden Enden fliegend angeordnete Steckverbinder hat (Anspruch 3).The third coaxial line is without disassembling the rotary coupling removable if this is the third coaxial line forming cables at both ends of flying connectors has (claim 3).
Bevorzugt befindet der wendelförmige Kanal sich unter einer den Mantel der feststehenden Baugruppe umschließenden Hülse (Anspruch 4) und ist damit gegen das Eindringen von Feuchtigkeit und Fremdkörpern geschützt. Die Hülse kann so ausgebildet werden, daß sie sich ebenfalls ohne Demontage der Drehkupplung abziehen läßt.The helical channel is preferably located below one sleeve surrounding the shell of the fixed assembly (Claim 4) and is therefore against the ingress of moisture and foreign bodies are protected. The sleeve can be designed in this way be that they can also be dismantled without Pull the rotary coupling off.
