 lockern. Die bekannten Druckfingeranordnungen verhindern nicht das Vibrieren und Ausbrechen der
Blechzähne. 



   Erfindungsgemäss erhalten die Druckfinger eine eigene Spannvorrichtung. Es kann jeder einzelne
Druckfinger eine eigene Spannvorrichtung oder es können auch mehrere Druckfinger eine gemeinsame
Spannvorrichtung haben. Die Segmente mit ausgeschnittenen Druckfingern aus unmagnetischem Material werden unter die Druckplatten eingebaut. Durch Druckschrauben werden die Druckfinger gegen die
Zähne gepresst. Diese Druckfinger können auch in Gelenkpfanne drehbar sein, um die sie durch die
Spannvorrichtung geschwenkt werden. Zwischen Druckfinger und Blechpaket können auch Keile aus unmagnetischem Material eingetrieben werden, die an den Druckfingern fixiert werden. 



   In der Zeichnung sind Ausführungsbeispiele der Erfindung dargestellt. In Fig. 1 ist 1 das gezahnte Blechpaket, 2 die Enddruckplatte, 3 das Druckfingersegment,   4   der Pressbolzen, 5 ist die Schraube, die erfindungsgemäss das Druckfingersegment an das Blechpaket presst. In Fig. 2 ist jedem Zahn ein eigener Druckfinger zugeordnet, der durch die Schraube   5   an das Blechpaket angepresst wird. 6 ist eine Pfanne im Druckfinger   3,   7 eine Wulst auf der Enddruekplatte 2, um die der Druckfinger gelenkig drehbar ist. 



   In Fig. 3 ist 8 ein Keil, der zwischen Blechpaket und Druckfinger eingetrieben und an diesem durch seine vorstehenden Ränder 9 gegen Verschiebung in der Umfangsrichtung fixiert ist. 



   PATENT-ANSPRÜCHE :
1. Druckfingeranordnung für gezahnte Blechpaket elektrischer Maschinen und Apparate, dadurch gekennzeichnet, dass die Druckfinger   (3)   eigene Spannvorrichtungen (5, 8) haben, durch die sie gegen die Zahnpakete verspannt werden.

    Pressure finger arrangement for toothed sheet metal stacks of electrical machines.
 EMI1.1
 loosen. The known pressure finger assemblies do not prevent the vibration and breaking out of the
Tin teeth.



   According to the invention, the pressure fingers receive their own clamping device. Anyone can do it
Pressure fingers have their own clamping device or several pressure fingers can share one
Have jig. The segments with cut-out pressure fingers made of non-magnetic material are installed under the pressure plates. The pressure fingers are pressed against the
Teeth pressed. These pressure fingers can also be rotatable in the joint socket around which they are passed through
Clamping device can be pivoted. Wedges made of non-magnetic material can also be driven in between the pressure fingers and the laminated core, which are fixed to the pressure fingers.



   Exemplary embodiments of the invention are shown in the drawing. In FIG. 1, 1 is the toothed laminated core, 2 the end pressure plate, 3 the pressure finger segment, 4 the press bolt, 5 is the screw which according to the invention presses the pressure finger segment onto the laminated core. In FIG. 2, each tooth is assigned its own pressure finger which is pressed against the laminated core by the screw 5. 6 is a pan in the pressure finger 3, 7 is a bead on the end pressure plate 2, around which the pressure finger can be pivoted.



   In FIG. 3, 8 is a wedge which is driven between the laminated core and the pressure finger and is fixed to it by its protruding edges 9 against displacement in the circumferential direction.



   PATENT CLAIMS:
1. Pressure finger arrangement for a toothed lamination stack of electrical machines and apparatus, characterized in that the pressure fingers (3) have their own clamping devices (5, 8) by means of which they are clamped against the tooth stacks.

Claims

2. Pressure finger arrangement according to claim l, characterized in that several contiguous pressure fingers (pressure finger segments) have common clamping devices (Fig. 1).

3. Pressure finger arrangement according to claim 1, characterized in that each individual pressure finger has its own clamping device (Fig. 2).

4. Pressure finger arrangement according to claim 1, 2 or 3, characterized in that the pressure fingers or pressure finger segments are mounted by means of joint sockets (6) around which they are pivoted by the clamping device.

5. Pressure finger arrangement according to claim 1 or one of the dependent claims, characterized in that the pressure fingers (3) which are separate from the press plates (2) are braced against the tooth packs by screws (5) seated in the press plates.

6. Pressure finger arrangement according to claim 1 or one of the dependent claims, characterized in that the pressure fingers are braced against the tooth packs by preferably non-magnetic wedges (8).

7. Pressure finger arrangement according to claim 6, characterized in that the wedges (8) are secured against displacement in the circumferential direction. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
