Description
Die Erfindung bezieht. sich auf ein Verfahren zur festen Verbindung gegeneinander isolierter Metallkörper, und zwar durch Gießen oder Spritzen. Eine solche Verbindungsart war bisher kaum durchführbar. Entweder litt dabei die Isolation oder die Verbindung war nicht genügend fest. Man stellte deshalb die Verbindung lieber durch Verklemmen oder Einspannen her, benötigte aber dazu entsprechend viele Teile. Oder man steckte oder preßte die Metallteile in ein Isolierstück ein und befestigte erst dieses mit dem anderen Metallteil.The invention relates. relate to a method of permanent connection metal bodies isolated from one another, by casting or spraying. One such a type of connection was previously hardly feasible. Either the isolation suffered or the connection was not strong enough. The connection was therefore made rather by jamming or clamping, but required a corresponding number of them Parts. Or you plugged or pressed the metal parts into an insulating piece and first attached this to the other metal part.
Die Erfindung vermeidet diese Schwierigkeiten. Erfindungsgemäß wird der eine Metallkörper, bevor er mit dem anderen umspritzt oder vergossen wird, an der Berührungsstelle mit einer Isolierschicht aus hitzebeständigem Silicon, vorzugsweise mit hitzebeständigem Füllstoff, versehen. Dieser Stoff hält kurzzeitig sehr hohe Temperaturen aus, ohne seine guten Isoliereigenschaften einzubüßen. Als Füllstoff eignen sich z. B. Quarzpulver und andere hitzebeständige anorganische Stoffe. Am besten verwendet man ein schon stärker polymerisiertes Silicon, das in einem Lösungsmittel gelöst und mit Füllstoff durchmischt ist. Es wird nach dem Auftragen noch einige Zeit wärmebehandelt, bis der Auftrag genügend 'hart ist, um den Gießvorgang auszuhalten. Nach diesem Verfahren lassen sich z. B. Kommutatoren, Schleifringkörper, Klemtnensätze, Stützer, Leiterdurchführungen usw. herstellen.The invention avoids these difficulties. According to the invention one metal body before it is overmolded or potted with the other the point of contact with an insulating layer made of heat-resistant silicone, preferably with heat-resistant filler. This substance holds very high for a short time Temperatures without losing its good insulating properties. As a filler are suitable e.g. B. Quartz powder and other heat-resistant inorganic substances. At the it is best to use a silicone that has already been polymerized to a greater extent and that is in a solvent is dissolved and mixed with filler. It will still be some after application Heat treated time until the job is hard enough to withstand the casting process. According to this method, for. B. Commutators, slip rings, sets of clamps, Make supports, conductor bushings, etc.
Die Erfindung wird an Hand der Zeichnung näher erläutert.The invention is explained in more detail with reference to the drawing.
In Fig. i ist ein Bolzen i bei 2 mit einer solchen Isolierschicht versehen und dann mit einem metallischen Halter 3 umspritzt.In Fig. I a bolt i is at 2 with such an insulating layer provided and then encapsulated with a metallic holder 3.
In Fig. 2 sind in derselben Weise Klemmen 6 in eine '\Letallfassung 7 eingespritzt. Die benachbarten freien Oberflächen sind zwecks Vermeidung von Kriechströmen mit der -gleichen oder einer anderen Isolierschicht 2o bedeckt.In Fig. 2, terminals 6 are in the same way in a '\ Letallfassungen 7 injected. The adjacent free surfaces are in order to avoid leakage currents covered with the same or another insulating layer 2o.
In Fig. 3 sind Schleifringe 4 in einen Na,benkörper 5 eingespritzt.In Fig. 3, slip rings 4 are injected into a Na, ben body 5.
In Fig. 4 sind die Lamellen 8 eines Kommutators auf der Innenseite mit hinterdrehten Rillen g versehen und mit der genannten Isolierschicht bedeckt, an den Rändern sind Isolierwinkelringe r i beigelegt. Die Lamellen sind gegeneinander, wie üblich, mit Glimmer oder ebenfalls mit einer solchen Siliconschicht isoliert. Die Narbe ist eingespritzt. Sie besteht aus Metall.In Fig. 4 the lamellae 8 of a commutator are on the inside provided with back-turned grooves g and covered with said insulating layer, insulating angle rings r i are enclosed at the edges. The slats are against each other, as usual, insulated with mica or also with such a silicone layer. The scar is injected. It is made of metal.
Die Erfindung bringt große Ersparnisse an Baustoff, Raum und Arbeitsaufwand. So läßt sich z. B. der Kommutator nach Fi. 4 und 5 mit besonders geringem Kupferaufwand herstellen, da die üb- lichen Schwalbenschwänze der Lamellen fortfallen, und er ist mechanisch und thermisch viel widerstandsfähiger als Kommutatoren mit Preßmassenahe.The invention brings great savings in building material, space and labor. So z. B. the commutator according to Fi. Manufacture 4 and 5 with particularly little copper, since the usual dovetails of the lamellas are omitted, and it is mechanically and thermally much more resistant than commutators with a molding compound.
