Description
Verfahren und Einrichtung zur Isolierung -.von Blechpaketen elektrischer Maschinen c'ür stopfbuchslose Heizwasserumwälzpumpen verwendet man Spaltrohr-,n otore, deren Kifigläufer durch das FIeizung:-#wasser einem starken r;orro;:ionsverschlei3 ausgesetzt sind.' Auch treten im Läufer UnwuchterUcheinungen auf', da sich der Läufer ungleich mit w'hisser vollsaugt. Diese Unwuchterscheinungen wirken sich wieder auf die E,ebensdauer der mit Wasser geschmierten Lager aus: Die rfindung bezweckt die Beseitigung der vorgenannten Nachteile und erreicht dies mit einem Verfahren zur IsoLierung von Blechpaketen elektrischer Maschinen, welches darin besteht, daß zwischen die einzelnen Eleche des fertiggestellten Paketes von dessen Bohrun; aus,ein Isolierstoff gepreßt wird. Das fertigmontierte Blechpaket, bei Käfigläufern bereits mit dem Käfig versehen, wird ohne Welle in eine Abdrückanlage gespannt und in dieser dann ein Gießharz oder ein sonstiger-geeigneter Isolierstoff durch Druckluft oder eine andere Druckerzeugungseinriehtung in die Paketbohrung gepreßt, von der er radial zwischen die einzelnen Bleche gelangt. Auf diese Weise ist das Läuferpaket vollst@.nait; mit einer Schutzisolierung versehen, die bei Verwendung des Läufers in einem Spaltrohrmotor ein Eindringen von @;asser in das 1°aket verhindert.Method and device for the insulation of sheet metal stacks electrical Machines for hot water circulation pumps without a stuffing box are used with canned, n otors, whose kiffi runners by the heating: - # water a strong r; orro;: ion wear3 are exposed.' Imbalance phenomena also occur in the runner, since the runner unequal with w'hisser soaks. These imbalance phenomena have an effect again The E, service life of the bearings lubricated with water from: The aim of the invention is the Eliminating the aforementioned disadvantages and achieves this with a method for IsoLierung of sheet metal stacks of electrical machines, which consists in that between the individual parts of the completed package from its drilling; made of an insulating material is pressed. The fully assembled sheet metal package, with cage rotors already with the cage provided, is clamped in a push-off system without a shaft and then inserted into it Cast resin or some other suitable insulating material by means of compressed air or another Druckzeugungseinriehtung pressed into the package bore, from which he radially between the individual sheets arrives. In this way the runner package is completely @ .nait; Provided with protective insulation, which when the rotor is used in a canned motor a penetration of @; water into the 1 ° aket is prevented.
Das Verfahren kann jedoch auch für jedes andere Blechpaket angewendet werden, wobei sich neben der Korrosionsfestigkeit noch folgende Vorteile ergeben: Die einzelnen Bleche sind durch den eingepreiten Isolierstoff gleichzeitig elektrisch gegeneinander isoliert, so daß eine vorherige Behandlung der einzelnen Bleche in Form von Glühen od.dgl. entfallen kann. weiterhin ist bei einem Käfigläufer gleichzeitig auch der Käfig gegenüber dem Eisenpaket isoliert, was bisher auf sehr große Schwierigkeiten stieß.However, the method can also be used for any other laminated core with the following advantages in addition to corrosion resistance: The individual sheets are electrical at the same time due to the insulated material isolated from each other, so that a previous treatment of the individual sheets in Form of glow or the like. can be omitted. is also at the same time with a squirrel cage The cage is also isolated from the iron package, which has so far caused great difficulties bumped.
Die Zeichnung zeigt . in rein schematischer Darstellung eine E.nrichtung zur Durchführung des erfindungsgemäßen Verfahrens. N1it 1 , ist eine Grundplatte und mit 2 eine Deckplatte bezeichnet, die auf Bolzen 3 so sitzen, daß sie gegeneinander verspannt werden können. In der Grundplatte 1 igt eine Bohrung 4 vorgesehen, die über eine Leitung 5 mit einem Behälter 6 in Verbindung steht. Dieser Behälter enthält einen flüssigen Isolierstoff 7 und ist über eine Zeitung 8-mit-einem .Drucklufterzeuger verbunden. üwischen@-die-Bodenplatten-1 und 2 wird ein bereits montiertes. Blechpaket: 9 unter Zwischenfügung von-Dichtungen.l0 und 11 so eingespannt',' däß° die ?aketbohrüng 12 mit der Bohrung 4 in der Grundplatte 1 in Verbindung steht. Durch die Öffnung der Druckluftleitung 8 wird der Isaliers@toff 7 über die Zeitung 5 und die Bohrung 4 in die Paketbohrung 1?_gepreßt und radial zwischen die einzelnen Bleche des Pakets--gedrückt. Tritt der Iso=lierstoff an der Außenwandung des Pakets aus, dann sieht mäm, dat' eine vollst#indge_ Isolierung erzielt ist und man stellt die Druckluft ab oder sperrt die .hei t@ing 1 bas so isolierte-Paket kann aus der Abdrückanlage entnommen und gegebenenfalls getrocknet werden, sofern man als -Isolierstoff-kein selbsthärtendes Mittel verwendet.The drawing shows. a purely schematic representation of a device for carrying out the method according to the invention. N1it 1, is a base plate and 2 denotes a cover plate, which sit on bolts 3 so that they are against each other can be braced. In the base plate 1 igt a bore 4 is provided which is in communication with a container 6 via a line 5. This container contains a liquid insulating material 7 and is via a newspaper 8-with-a .Drucklufterzeuger tied together. üwischen @ -die-Bodenplatten-1 and 2 becomes an already assembled. Sheet metal package: 9 with the interposition of gaskets, 10 and 11 so clamped 'that' the? Aketbohrüng 12 is in communication with the bore 4 in the base plate 1. Through the opening the compressed air line 8 is the Isaliers @ toff 7 over the newspaper 5 and the hole 4 into the package bore 1? _ Pressed and pressed radially between the individual sheets of the package. If the insulating material emerges on the outer wall of the package, then mäm, dat ' a complete # indge_ isolation is achieved and the compressed air is switched off or blocked the .hei t @ ing 1 bas so insulated package can be removed from the extraction system and optionally dried, provided that the insulation material is not a self-curing one Funds used.
