verwendet.
Diese Unterlagstücke sind aus geeignetem Metall gegossen oder gepresst und besitzen einen U-förmigen Teil 9, welcher die Bandagendrähte aufnimmt und in ihrer Lage und ihrem
EMI2.2
Abstand sichert als auch die Ventilatorwirkung beträchtlich erhöht. Fig. 4 zeigt ein solches Unterlagstück in Seitenansicht und Schnitt. Diese Unterlagstücke werden in geeigneten Abständen oder auch dicht aneinanderliegend zwischen die Wickelköpfe geschoben und dann die Bandagen daraufgewickelt. Hiedurch werden die Unterlagstücke befestigt und gegen Herausschleudern gesichert.
Statt einzelne Unterlag- und Distanzstücke nach Fig. 4 zu verwenden, kann man gemäss Fig. 5 auch eine beliebige Anzahl von ihnen zu einem segmentförmigen Gussstut k vereinigen. Ebenso können mehrere solcher Segmente durch achsiale Verbindungsstücke oder Stege zu einem zusammenhängenden Distanzstück für mehrere Wickelköpfe und Bandagen ausgebildet werden. An Stelle der Gussstücke können naturgemäss auch entsprechend geformte, aus Blech gestanzte und gebogene Stücke treten.
PATENT-ANSPRÜCHE :
1. Einrichtung zur Befestigung der Stirnverbindungen von Wicklungen elektrischer Maschinen nach Patent Nr. 48832, bei welcher die bogenförmigen Wicklungsköpfe (4) auf Unterlagsringen (5) aufliegen, dadurch gekennzeichnet, dass diese Wicklungsköpfe gegen die durch Luftzwischenräume voneinander getrennten Unterlagsringe mittels konzentrisch zu diesen verlaufender Bandagen oder Schrumpfringe (6) gepresst werden, zum Zwecke, der Kühlluft ungehinderten Durchgang zwischen den Wickelköpfen zu gestatten.

used.
These shims are cast or pressed from suitable metal and have a U-shaped part 9, which receives the bandage wires and their position and their
EMI2.2
Clearance ensures that the fan effect is increased considerably. Fig. 4 shows such a base piece in side view and section. These base pieces are pushed between the winding heads at suitable intervals or close together and the bandages are then wound on them. As a result, the base pieces are attached and secured against being thrown out.
Instead of using individual base and spacer pieces according to FIG. 4, any number of them can also be combined into a segment-shaped cast piece k according to FIG. Likewise, several such segments can be formed into a coherent spacer for several winding heads and bandages by means of axial connection pieces or webs. In place of the cast pieces, of course, appropriately shaped pieces punched from sheet metal and bent can also be used.
PATENT CLAIMS:
1. Device for fastening the end connections of windings of electrical machines according to patent no. 48832, in which the arcuate winding heads (4) rest on washer rings (5), characterized in that these winding heads against the washer rings separated by air gaps by means of concentric rings Bandages or shrink rings (6) are pressed in order to allow the cooling air to pass unhindered between the winding heads.
