Description
Es wurde bereits vorgeschlagen, die Dauermagnetkörper durch Schweißung oder Lötung mit dem Halter zu verbinden. Bei manchen Magneteis, namentlich bei Magneten aus einer spröden Nickel und Aluminium enthaltenden Eisenlegierung, läßt sich aber dadurch mitunter keine genügend dauerhafte Verbindung mit .dem Halter erzielen. Die Erfindung beseitigt diese Schwierigkeiten.It has already been proposed to weld the permanent magnet body or soldering to connect to the holder. With some magnet ice, especially with magnets from a brittle iron alloy containing nickel and aluminum, but can as a result, it may not be possible to achieve a sufficiently permanent connection with the holder. The invention overcomes these difficulties.
Erfindungsgemäß wird .an der Schweiß-oder Lätsitelle ,des, Dauermagneten ein Metallmantel nach dem Schoopsch en Verfahren herumgespritzt. Dieser Metallmantel, dervorzugsweise aus Kupfer hergestellt ist, umschließt den Dauermagnetkörper ringartig. Dadurch :ergibt sich bei schlechter Oberflächenhaftung eine feste, dauerhafte Verbindung zwischen dem Belag und dem Dawermagnetkörper. Auf diesen Belag wird nun der Halter aufgelötet oder aufgeschweißt. Es empfehlt sich, vorher den mit Belag versehenen Teil des. Dauermagnetkärpers in eine Zinn- o. dgl. Schmelze zu tauchen. Das Zinn dringt dann in die Poren des Metallbelages und legiert sich zum Teil mit diesem Metall. Der Metallbelag wird dadurch verfestigt und das Anlöten bzw. Anschweißen des. Halters, wesentlich terleichtert.According to the invention, on the welding or soldering part, the permanent magnet a metal jacket was sprayed around using the Schoopsch en method. This metal jacket, which is preferably made of copper, surrounds the permanent magnet body like a ring. As a result: if the surface adhesion is poor, there is a firm, permanent connection between the pad and the Dawermagnet body. The holder is now on this covering soldered or welded on. It is advisable to cover the covered area beforehand To immerse part of the permanent magnet body in a tin or similar melt. The tin then penetrates the pores of the metal covering and is partly alloyed with it Metal. The metal covering is thereby solidified and the soldering or welding des. Holder, much easier.
Der Vorteil der Erfindung ist in dieser leicht und vor allem ohne Schädigung des hochempf ndlichen Magnetmaterials durchführbaren Verbindung von Dauermagnet und Halter zu sehen.The advantage of the invention is easy in this and, above all, without Damage to the highly sensitive magnetic material, which can be connected to permanent magnets and keeper to see.
Die Erfindung soll an Hand der Zeichnung niäher erläutert werden.The invention will be explained in more detail with reference to the drawing.
i ist ein U-förmiger Dauermagnetkörper aus Hochleistungsmagnetstahl. a ist die aufgebrachte, um den ganzen Umfang des Magnetkörpers herumlaufende Metallschicht. 3 ist der Halter, der bei q. mit der Metallschicht verlötet ist. Beim Aufspritzen der Metallschicht werden die Polenden 5 des Magnetkörpers auf irgendeine Weise abgedeckt.i is a U-shaped permanent magnet body made of high-performance magnetic steel. a is the applied metal layer running around the entire circumference of the magnetic body. 3 is the holder who is at q. is soldered to the metal layer. When spraying the metal layer, the pole ends 5 of the magnetic body are covered in some way.
