Description

Armierung von Spulen fG..eisenlose Induktionsöfen Zusatz zum Patent 625 933 Das Hauptpatent betrifft eine Armierung von Spulen für eisenlose Induktionsöfen mit Hilfe von Kammleisten, bei ,denen die zwischen den Windungen liegenden Teile der Leiste, die Zähne des Kammes, entweder dadurch gebildet werden, daß Isolierplättchen hälftig in entsprechende Nuten eingesetzt, oder breite Nuten in eine entsprechend dickere Leiste eingefräst werden. Die so entstehenden Kammleisten bedürfen zu ihrer Herstellung sehr exakter Ausführung, da von der ,genauen Einhaltung der Abstände zwischen den Zähneu des Kammes die Betriebssicherheit der Armatur ,abhängt.Reinforcement of coils fG. Ironless induction furnaces Addition to the patent 625 933 The main patent relates to a reinforcement of coils for ironless induction furnaces with the help of comb strips, in which the parts lying between the windings the bar, the teeth of the comb, are either formed by insulating plates half inserted in corresponding grooves, or wide grooves in a corresponding thicker bar can be milled. The resulting comb strips require their Production of very exact execution, because of the exact observance of the distances between the teeth of the comb the operational safety of the valve depends.

Erfindungsgemäß wird die Herstellung solcher Kammleisten ganz wesentlich dadurch vereinfacht, daß die Kammleiste mit einer durchgehenden Nut versehen wird, in die an Stelle von fest eingebauten oder durch Fräsüng herausgearbeiteten Zähnen Winkel aus Isoliermaterial so eingesenkt werden, daß sie sich in Richtung der Nut beliebig bewegen können.According to the invention, the production of such comb strips becomes very essential simplified by the fact that the comb bar is provided with a continuous groove, in the teeth instead of permanently installed or milled out teeth Brackets made of insulating material are countersunk so that they are in the direction of the groove can move at will.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Fig. i zeigt die Aufsicht ,auf die Kammleiste i von innen. Man erkennt deutlich die durchgehend eingefräste Nut z, in die die Winkel 3 (Fig. 2) eingesetzt sind. In der Fig. z ist ein seitlicher Teilschnitt einer gemäß: der Erfindung armierten Spule dargestellt. In der Kammleiste i bzw. in deren Nut 2 sind die Winkel 3 geführt, deren ,abgebogene Teile zwischen den Windungen d. der Spule liegen.The drawing shows an exemplary embodiment of the subject matter of the invention shown. Fig. I shows the plan view of the comb bar i from the inside. One recognises clearly the continuously milled groove z into which the angle 3 (Fig. 2) is used are. In Fig. Z is a side partial section of a reinforced according to: the invention Coil shown. The angles 3 are guided in the comb strip i or in its groove 2, their bent parts between the turns d. the coil.

Durch die lose Führung der Kammwinkel in der Nut der Kammleiste sind Brüche des Isoliermaterials und damit verbundene Überschlage zwischen den Spule windungen ausgeschlossen: Die Kammwinkel können sich in der Nut der Kammleiste in Vertikalrichtung beliebig bewegen und haben keine für ihre Dauerhaftigkeit schädliche Abscherbeanspruchungaufzunehmen. Eine Befestigung der Winkel in der Nut erübrigt sich, da diese durch die Spule selbst in der Nut in der Klemmleiste festgehalten werden.Due to the loose guidance of the comb angles in the groove of the comb bar Breaks in the insulating material and the associated flashover between the coil Twists excluded: The comb angles can be in the groove of the comb bar in Move in any vertical direction and do not have any detrimental to their durability To absorb shear stress. There is no need to fasten the angle in the groove because this is held by the coil itself in the groove in the terminal strip will.
