Description

Jürgen schünhoff Münstereifel Am Nötbener Berg "Halterung von Nutenschließern in Schlitzen, die in den seitenwänden von radialen Nuten bei Motoren axialer Bauart angeordnet sind". Jürgen Schünhoff Münstereifel Am Nötbener Berg "Mounting of slot closers in slots that are in the side walls of radial slots are arranged in motors of axial design ".

Bei Motoren axialer Bauart werden in die radialen Nuten, die vorzugsweise parallele seitenwände aufweisen, fertige Wicklungen eingelegt. Zur Verbesserung des Magnetfeldes verwendet man sog. Nutensohließer, denen die Aufgabe zufällt, die Nuten am äußeren Ende bis auf einen sehr schmalen Spalt zu schließen. Die Nutenschließer bestehen aus einem perforierten Blechstreifen der @estalt, daß sie gleichsam aus zwei Blechstreifen bestehend aussehen, die durch mehrere Stege verbunden sind. Sie wurden von der Seite einzeln eingeschoben und anschließend verspannt, was sehr umständlich ist. Der Neuerung liegt die Aufgabe zugrunde, diese Nachteile zu beseitigen.In the case of motors of an axial design, finished windings are inserted into the radial grooves, which preferably have parallel side walls. To improve the magnetic field, so-called slot bottom molders are used, which have the task of closing the slots at the outer end except for a very narrow gap. The slot closers consist of a perforated sheet metal strip of the shape that they look like two sheet metal strips that are connected by several webs. They were pushed in individually from the side and then tightened, which was very cumbersome is. The innovation is based on the task of eliminating these disadvantages.

Zu diesem Zweck wird eine Halterung von Nutenschließern in Schlitzen, die in den Seitenwänden der radialen Nuten bei Motoren axialer Bauart angeordnet sind, neuerungsgemäß vorgeschlagen, daß die Außenkanten der Schlitze gegenüber der Innenkanten zurückspringen.For this purpose, a holder of slot closers in slots, which are arranged in the side walls of the radial grooves in motors of the axial type are proposed according to the innovation that the outer edges of the slots opposite the Inside edges spring back.

Hierdurch wird erreicht, daß man die Nutenschließer einfach von oben in die Nut einlegen kann, wobei das Verspannen selbst in der einfachsten Weise dadurch erfolgt, daß die in der Längsachse gewölbten Nutenschließer flachgedrückt werden. In der Zeichnung ist die Neuerung beispielsweise und schematisch veranschaulicht : Der stator 1, von dem nur ein Ausschnitt gezeigt ist, weist in bekannter Weise radiale Nuten 2 auf, von denen nur eine gezeigt ist und zwar mit einer Nutenbreite bl. In diese werden nichtdargestellte fertige Uicklungen eingelegt. AN äußeren Ende der Nuten sind schlitze 4 vorgesehen, von denen die äußeren Kanten 4b gegenüber den inneren Kanten 4a zurückspringen, so daß ein Abstand b2 der äußeren Schlitzkanten 4b entsteht, der größer ist als der Abstand b1 der Nutenwände bzw. der inneren schlitzkante 4a. In die Schlitze 4 werden die Nutenschließer 3 im flachgebogenen Zustand eingelegt (Abb. i) und hierauf durch Klopfen oder Druck in die Strecklage gemäß Abb. 2 gebracht. SchutzanspruchThis ensures that the slot closer can simply be opened from above can insert into the groove, the bracing itself in the simplest way thereby takes place that the groove closers curved in the longitudinal axis are flattened. In the drawing, the innovation is illustrated as an example and schematically : The stator 1, of which only a section is shown, has in a known manner radial grooves 2, only one of which is shown, with a groove width bl. Finished wraps (not shown) are inserted into these. At the outer end of the grooves 4 slots are provided, of which the outer edges 4b opposite spring back the inner edges 4a, so that a distance b2 of the outer slot edges 4b arises, which is greater than the distance b1 between the groove walls or the inner slot edge 4a. The slot closers 3 are inserted into the slots 4 in the flat-bent state (Fig. I) and then brought into the extended position according to Fig. 2 by tapping or pressure. Claim to protection
