Description

Schaltmagnet Die Neuerung betrifft Schaltmagnete, insbesondere solche, die unter Öl arbeiten, wie Elektromagnete für die Betätigung von Schaltventilen in hydraulisch gesteuerten , Getrieben. Zur feuchtigkeitsdichten Lagerung der Spule von Elektromagneten wurde die Spule bisher in Lacken im Vakuum getränkt und mit Gießharzen umhüllt. Diese Isolierung reicht erfahrungsgemäß nicht aus, um das Eindringen von Spuren von Öl in die Spule zu verhindern, wenn der Magnet im Öl arbeitet.Switching magnet The innovation concerns switching magnets, especially those that work under oil, such as electromagnets for the Actuation of switching valves in hydraulically controlled , Driven. For moisture-proof storage of the coil of Electromagnets, the coil was previously soaked in lacquer in a vacuum and encased with casting resin. Experience has shown that this insulation is not sufficient to prevent traces of oil from entering the coil when the magnet is working in the oil.

Nach vorliegender Neuerung werden in einem Elektromagnet Ringdichtungen angeordnet, um den Zutritt von Öl zu den Spulendrähten und Kontakten zu verhindern. According to the present innovation, ring seals are used in an electromagnet arranged to prevent oil from entering the coil wires and contacts.

Die Ringdichtungen sind zweckmäßigerweise aus Werkstoffen, die gegen Temperaturen über 1000 und gegen chemische Einwirkungen durch Ölzusätze beständig sind. The ring seals are expediently made of materials that oppose Temperatures over 1000 and resistant to chemical effects from oil additives are.

Die Zeichnung stellt ein Ausführungsbeispiel der Neuerung dar. The drawing shows an embodiment of the innovation.

Es ist 1 der Magnetkörper eines Topfmagneten. Im Innern des Magnetkörpers ist die Magnetspule 2 untergebracht. It is 1 the magnet body of a pot magnet. Inside the magnet body the solenoid 2 is housed.

Der Magnetkörper wird auf'einer Seite durch einen Deckel 3 abgeschlossen, der mit der Magnetspule den Spulenkörper bildet und durch nicht gezeichnete Schrauben mit dem Magnetkörper 1 verbunden ist. In einer Bohrung des Magnetkörpers und im Innern der Spule ist der Anker 4 untergebracht, der in einer Buchse 5 und einer Lagerplatte 6 längsbeweglich gelagert ist. Das freie Ende 7 des Windungsdrahtes der Magnetspule 2 ist mit einem Anschlußbolzen 8 verlötet, der in einem Isolierstück 9 befestigt ist. Das Isolierstück ist mit einem eingepreßten Ring 10 versehen und auf dem Magnetkörper aufgeschraubt. Ein Kabelschuh 17 ist zwischen zwei Klemmuttern 18 und 19 auf dem Anschlußbolzen 8 aufgeschraubt und von einer Schutzhülse 20 umgeben.The magnetic body is closed on one side by a cover 3, which forms the coil body with the solenoid and by screws, not shown is connected to the magnet body 1. In a hole in the magnet body and in the Inside the coil is housed the armature 4, which is in a socket 5 and a bearing plate 6 is mounted so as to be longitudinally movable. The free end 7 of the winding wire the solenoid 2 is soldered to a connecting bolt 8, which is in an insulating piece 9 is attached. The insulating piece is provided with a pressed-in ring 10 and screwed onto the magnet body. A cable lug 17 is between two clamping nuts 18 and 19 are screwed onto the connecting bolt 8 and surrounded by a protective sleeve 20.

Die Spule 2 ist auf einem Rohr"11 aufgewickelt, welches mit dem Deckel 3 und einer Scheibe 12 verlötet ist. In dem Deckel 3 ist eine Nut am Umfang eingedreht, in welcher ein O-Ring 13 liegt. Dieser dichtet die Spule nach außen ab. The coil 2 is wound on a tube 11, which is connected to the cover 3 and a disk 12 is soldered. In the cover 3 a groove is screwed on the circumference, in which an O-ring 13 is located. This seals the coil from the outside.

Ein weiterer O-Ring 14 liegt in einer Nut 15 des Magnetkörpers 1 und dichtet die Spule gegen Öl ab, welches vom Anker her eintritt. Ein O-Ring 16 liegt in einer Nut des Isolierstückes 9 und dichtet das Isolierstück gegen den Magnetkörper l ab. Another O-ring 14 lies in a groove 15 of the magnet body 1 and seals the spool against oil entering from the armature. One O-ring 16 lies in a groove of the insulating piece 9 and seals the insulating piece against the magnet body l from.
