Description

Es ist bekannt, die Polspulen in elektrischen Maschinen statt durch Zwischenlagen aus kittgetränkten Bändern auf die Weise an den Polen bzw. dem Gehäuse zu befestigen, daß ein selbsthärtender oder durch Wärme erhärtender Stoff (Kunstharz) in flüssiger oder plastischer Form in die Räume zwischen Spulen und Pole oder Gehäuse eingeführt wurde.It is known to be held by the pole coils in electrical machines Intermediate layers made of cement-soaked tapes in the manner on the poles or the housing to fix that a self-hardening or heat-hardening material (synthetic resin) in liquid or plastic form in the spaces between coils and poles or housings was introduced.

Die Anwendung dieser Methode beschränkt sich jedoch auf Maschinen oder Spulengehäuse, die entweder voll mit dem Kunstharz ausfüllbar waren oder deren Bauart das Eindringen der Füllmasse in freizuhaltende Gehäuseteile verhinderte. Ferner eignet sich dieses Verfahren nicht für die Befestigung von Spulen, deren Ausbau zu Reparaturzwecken nach einer bestimmten Betriebsdauer -zu erwarten ist.However, the use of this method is limited to machines or bobbin cases that could either be completely filled with the synthetic resin or their Design prevented the filling compound from penetrating into housing parts that were to be kept free. Furthermore, this method is not suitable for the attachment of coils whose Removal for repair purposes after a certain period of operation is to be expected.

Nach der Erfindung sollen zur Erweiterung der Anwendungsmöglichkeit mit-Kitt oder Kunstharz gefüllte, flexible Schläuche als Zwischenlagen Verwendung finden. Der Füllstoff kann dabei entweder vor der Montage bereits in die Schläuche gefüllt oder nach dem Einbau von außen in diese eingepreßt werden.According to the invention are intended to expand the application possibilities Flexible hoses filled with putty or synthetic resin are used as intermediate layers Find. The filler can either be in the hoses before assembly filled or pressed into this from the outside after installation.

Neben der bedeutenden Arbeitsersparnis und dem Umstand, daß die Montagearbeiten nicht durch die bisher üblichen klebenden, kittgetränkten Textilzwischenlagen behindert werden und bei nachträglichem Einpressen des Kitts sogar die Maschine vorher komplett mit losen Spulen montierbar ist, können die auszufüllenden Hohlräume weit größere räumliche Unebenheiten und Volumen aufweisen. Es besteht ferner die Möglichkeit, den Preßdruck, solange die Masse noch elastisch ist, gedrosselt beizubehalten, um eine Vorspannung zu schaffen, die das Schwinden während des Erhärtungsprozesses ausgleicht.In addition to the significant labor savings and the fact that the assembly work not hindered by the previously customary adhesive, cement-soaked textile intermediate layers and if the putty is subsequently pressed in, the machine can even be completed beforehand can be mounted with loose coils, the cavities to be filled can be much larger have spatial unevenness and volume. There is also the possibility the pressing pressure, as long as the mass is still elastic, to keep throttled in order to to create a pre-tension that reduces the shrinkage during the hardening process compensates.

Wirkungsweise und Vorrichtung zur Durchführung dies neuen Verfahrens sind in der Zeichnung schematisch angedeutet. Fig. I zeigt die zwischen Spule 3 und den Wänden --von Pol 2 -bzw. Gehäuse I eingelegten Schläuche 6, die zweckmäßig aus elastischem Kunststoff hergestellt werden. Den Schläuchen ist seitlich Raum zur Ausdehnung gelassen.Mode of operation and device for carrying out this new method are indicated schematically in the drawing. Fig. I shows the between coil 3 and the walls - from pole 2 - or. Housing I inserted hoses 6, the appropriate made of elastic plastic. There is space on the side for the hoses left to expand.

Bei der Zuführung des Kitts von außen wird dieser (vgl. Fig. 2) den in den Zwischenräumen befindlichen Schläuchen mittels einer Kittpresse durch Bohrungen 5, 5' zugeführt. Für den Ansatz der Kittpresse sind im Gehäuse Gewindeansätze 7,7' vorgesehen.When the putty is supplied from the outside, this (see FIG. 2) is the Hoses located in the interstices by means of a putty press through holes 5, 5 'supplied. For the attachment of the putty press, there are 7.7 'threads in the housing intended.
