Description

Verfahren zum Isolieren der Haltebolzen von Körpern elektrischer Maschinen oder Apparate Das Isolieren von Haltebolzen solcher Körper elektrischer Maschinen und Apparate, die aus einzelnen Blechen zusammengesetzt sind, bereitete erhebliche Schwierigkeiten, da die Bolzen gegenüber den Blechen durch aufgeschobene Isolierhülsen oder aufgewickeltes, mit Kunstharz getränktes Papier isoliert werden mußten. Besonders bei größeren Blechpaketen wurde das Einsetzen der Haltebolzen durch die vor dem Einsetzen aufgebrachte Isolierschicht wesentlich erschwert, da beim nicht genauen Übereinstimmen des isolierten Bolzendurchmessers mit den Blechpaketbohrungen die Zentrierung für die Bleche verlorerigeht oder die Bolzen nachgearbeitet werden müssen.Method of isolating the retaining bolts of bodies of electrical machines or apparatus The isolation of retaining bolts of such bodies of electrical machines and apparatuses which are composed of individual sheets of metal prepared considerable Difficulties because the bolts are pushed against the metal sheets by insulating sleeves or wrapped paper soaked in synthetic resin had to be insulated. Particularly in the case of larger laminated cores, the insertion of the retaining bolts was made easier by the front of the Insertion of the applied insulating layer is made much more difficult because the inaccurate Coincide with the insulated bolt diameter with the laminated core bores Centering for the sheets is lost or the bolts have to be reworked.

Es ist auch bekannt, lamellierte Magnetsysteme mit einer Isolierschicht, die durch Spritzen aufgebracht wird, zu umgeben. In diesem Falle dient die Isolationsschicht weder zum Zentrieren noch zum Zusammen*-halten der lamellierten Körper. Eine Isolation von für den Körper bestimmte Halteteile kommt dabei nicht in Betracht.It is also known to use laminated magnet systems with an insulating layer, which is applied by spraying to surround. In this case, the insulation layer is used neither for centering nor for holding the laminated bodies together *. An isolation holding parts intended for the body are out of the question.

Durch das Verfahren der vorliegenden Erfindung wird es ermöglicht, die Haltebolzen gegenüber der Bohrung der geschichteten Blechkörper dadurch schnell und einwandfrei zu isolieren, daß zwischen Haltebolzen und Bohrung Isoliermaterial in flüssigem oder plastischem Zustand eingegossen bzw. eingespritzt wird, was nach dem Erstarren als Halte- oder Bindemittel zwischen Bolzen und Blechpaket dient.The method of the present invention makes it possible to the retaining bolt against the bore of the layered sheet metal body thereby quickly and to insulate properly that insulating material between the retaining bolt and the hole is poured or injected in liquid or plastic state, what after serves to solidify as a holding or binding agent between the bolt and the laminated core.

Ein ähnliches Verfahren ist zum Isolieren und Ausfüllen der eingesetzten Wicklungen elektrischer Maschinen angewandt worden, jedoch soll dabei das unter Druck eingegossene Material nicht zum Zusammenhalten der Blechkörper bzw. zum Isolieren von Halteteilen des Blechkörpers dienen.A similar procedure is used to isolate and fill in Windings of electrical machines have been used, but this is intended under Pressure-poured material is not used to hold the sheet metal bodies together or to isolate them serve of holding parts of the sheet metal body.

Das Eingießen bzw. Einspritzen des Isoliermaterials nach der vorliegenden Erfindung kann mit kleinen transportablen Apparaten oder mit einer stationären Anlage erfolgen, welche direkt an die als Gießform dienenden Blechkörper angeschlossen werden, so daß sämtliche oder mehrere Gußstellen einer Maschine oder eines Apparates auf einmal gespritzt bzw. gegossen werden können.Pouring or injecting the insulating material according to the present invention Invention can be done with small portable apparatus or with a stationary system take place, which are connected directly to the sheet metal body serving as a casting mold so that all or more casting points of a machine or apparatus can be injected or poured at once.
