Description

Form zum Umgießen der Wickelköpfe von Elektromotoren mit Gießharz Die Erfindung betrifft eine Form zum Umgießen der Wickelköpfe von Elektromotoren mit Gießharz.Mold for encapsulating the winding heads of electric motors with cast resin The invention relates to a mold for encapsulating the winding heads of electric motors with cast resin.

Zum Schutz der Wicklungen von Elektromotoren, insbesondere gegen Witterungseinflüsse, umgibt man diese mit einer flüssigkeitsdichten Isolierung, beispielsweise Kunstharz.To protect the windings of electric motors, especially against the effects of the weather, surround them with a liquid-tight insulation, for example synthetic resin.

Gleichzeitig versucht man hierbei die Wicklungen in einem zulässigen Maße zusammenzudrücken, um das Motorenvolumen zu verringern.At the same time, one tries to keep the windings within a permissible range Compress dimensions to reduce engine volume.

Die erforderlichen Arbeitsgänge werden unterVerwendung von Formen durchgeführt. In mehreren Arbeitsgängen unter Verwendung mehrerer Formen werden die Motorenwicklungen nach und nach zusammengepreßt. In einer Spezialform wird die so vorbereitete Wicklung mit Gießharz umgeben und beispielsweise unter Druck und Hitze das Einhärten durchgeführt.The required operations are performed using molds carried out. Be in multiple operations using multiple molds the motor windings are gradually compressed. In a special form, the so prepared winding surrounded with casting resin and, for example, under pressure and Heat curing done.

Dieses bekannte Verfahren ist umständlich, weil eine Vielzahl Formen benötigt wird. Dabei ist der Zeitaufwand erheblich, und außerdem werden auch nur die Zwischenräume zwischen den einzelnen Drähten ausgefüllt.This known method is cumbersome because of the multitude of shapes is needed. The expenditure of time is considerable, and besides, only the spaces between the individual wires are filled.

Um den geschilderten Nachteilen zu begegnen, wird erfindungsgemäß eine Form zum Umgießen von Wickelköpfen vorgeschlagen, bei der die das Gießharz formende Innenfläche der Form Preßflächen im Abstand so angeordnet aufweist, daß der Gießharzfluß unbehindert ist.In order to counter the disadvantages outlined, according to the invention proposed a mold for encapsulating winding heads, in which the casting resin forming inner surface of the mold comprises pressing surfaces spaced apart so that the flow of casting resin is unhindered.

Man benötigt also nur eine Form zum Umgießen der Wickelköpfe von Elektromotoren mittels Gießharz, in die das Statorblech mit der Wicklung eingeführt und zusammengepreßt wird.So you only need one mold to encapsulate the winding heads of electric motors by means of casting resin, into which the stator lamination with the winding is inserted and pressed together will.

Außerdem ist diese Form in an sich bekannter Weise so ausgebildet, daß die Lager, gegebenenfalls Flansche u. dgl., mit angegossen werden können.In addition, this shape is designed in a manner known per se so that that the bearings, possibly flanges and the like, can be cast on.
