Description

Antriebsvorrichtung für drehbar gemachte Röntgenröhren Zusatz ztziet°'tent 643 507 Das Hauptpatent betrifft eine Glühkathodenentladungsröhre für Hochspannung mit Zwischenwand, die aus Isolierstoff besteht und die Elektroden völlig umhüllt. Diese Zwischenwand umhüllt ferner die mit den Elektroden verbundenen, im Vakuum befindlichen Metallteile derart im Abstand und ist mit derartigen Öffnungen zwischen Mantelraum und Entladungsraum versehen, daß geradlinig von den Metallteilen ausgehende Ladungsträger praktisch nicht in den Mantelraum gelangen können.Drive device for rotatable X-ray tubes add-on ztziet ° 'tent 643 507 The main patent relates to a hot cathode discharge tube for high voltage with a partition made of insulating material and completely enveloping the electrodes. This intermediate wall also envelops the electrodes connected to the electrodes in a vacuum located metal parts so in the distance and is with such openings between Provide shell space and discharge space that straight out from the metal parts Load carriers can practically not get into the shell space.

Die Eigenschaft einer Entladungsröhre gemäß dem Hauptpatent, daß in der unmittelbaren Umgebung ihrer Entladungszone geerdete leitende Körper angebracht werden können, ist gemäß der vorliegenden Erfindung bei einer um ihre Längsachse drehbar gemachten Röntgenröhre . in vorteilhafter Weise ausgenutzt. Infolge der Möglichkeit der Mittelerdung und der gleichmäßigen Potentialverteilung auf der Außenseite der Röhre ist die Unterbringung der drehbar gemachten Röntgenröhre in einem Schutzgehäuse wesentlich erleichtert. Es sind Anordnungen bekannt, bei denen drehbar gemachte Röntgenröhren mittels einer Transmission oder einer starren Welle mit einem fest angeordneten Antriebsmotor verbunden sind. Solche mechanischen Verbindungen erschweren die Einstellbarkeit der Röntgenröhre beträchtlich.The property of a discharge tube according to the main patent that in earthed conductive bodies are attached to the immediate vicinity of their discharge zone is, according to the present invention, at one about its longitudinal axis rotatable X-ray tube. exploited in an advantageous manner. As a result of Possibility of central earthing and uniform potential distribution on the outside the tube is the accommodation of the rotatable X-ray tube in a protective housing much easier. There are known arrangements in which made rotatable X-ray tubes by means of a transmission or a rigid shaft with a fixed arranged drive motor are connected. Such mechanical connections make it difficult the adjustability of the X-ray tube is considerable.

Gemäß der Erfindung wird dieser Nachteil dadurch beseitigt, daß der Antriebsmotor unmittelbar an der Röntgenröhre angebracht ist, so daß der Motor beim Einstellen der Röntgenröhre mit dieser bewegt werden kann, ohne die Einstellbarkeit der Röntgenröhre zu beeinträchtigen. Der Statur des Motors ist dabei am Schutzgehäuse angebracht, während der Rotor mit dem einen Ende des Röntgenröhrenglashohlkörpers in starrer Verbindung steht. Handelt es sich um eine drehbar gemachte Röntgenröhre mit mechanischer Ablenkung des Kathodenstrahlenbündels, so müssen Stätor und Rotor in entsprechendem Abstand von der zum Ablenken der Kathodenstrahlen dienenden Vorrichtung angebracht sein, -weil sonst, abgesehen von Schwierigkeiten beim Zusammenbau der Röntgenröhre, die gegenseitige Beeinflussung der Magnetfelder sich störend bemerkbar machen würde.According to the invention, this disadvantage is eliminated in that the Drive motor is attached directly to the X-ray tube, so that the motor when Adjustment of the X-ray tube with this can be moved without the adjustability affect the X-ray tube. The stature of the motor is on the protective housing attached, while the rotor with one end of the X-ray tube glass hollow body is in rigid connection. Is it a rotatable X-ray tube? with mechanical deflection of the cathode ray beam, the stator and rotor must at a corresponding distance from the device used to deflect the cathode rays be appropriate, -because otherwise, apart from difficulties in assembling the X-ray tube, the mutual influence of the magnetic fields is noticeable disturbing would do.

Der Motor kann auf der Anoden- oder Kathodenseite, etwa am Anoden- bzw. Kathodensockel, angebracht werden und gegen Erde durch Zwischenschalten eines Transformators isoliert sein. Ist der Motor auf der Kathodenseite angeordnet, so kann die den Motor speisende Wicklung zweckmäßig auf dem Heizstrorntransformator für die Glühkathode angebracht sein.The motor can be on the anode or cathode side, for example on the anode or cathode base, are attached and to earth by the interposition of a Transformer isolated. If the motor is arranged on the cathode side, so the winding that feeds the motor can expediently be placed on the heating current transformer for the hot cathode.

Ein Ausführungsbeispiel einer Vorrichtung gemäß der Erfindung ist in der Abbildung im Längsschnitt wiedergegeben.An embodiment of a device according to the invention is reproduced in the figure in longitudinal section.

Der Glashohlkörper i der Röntgenröhre ist in der Schutzhülle 2 mittels der Kugellager 3, :I drehbar gelagert. Am Antikathodenende ist, mit der Hülle 2 fest verbunden, der Statur 5 des Antriebsmotors angebracht, innerhalb dessen sieh der mit der Antikathodenkappe fest verbundene Rotor 6 drehen kann.The hollow glass body i of the X-ray tube is in the protective cover 2 by means the ball bearing 3,: I rotatably mounted. At the end of the anticathode is, with the sleeve 2 firmly connected, attached to the stator 5 of the drive motor, within which see the rotor 6, which is fixedly connected to the anticathode cap, can rotate.
