Description

Die Erfindung betrifft eine Anordnung zum Befestigen von Innenteilen elektrischer Maschinen mittels Beines H.alteriiiges. Bei der Befestigung von Innenteilen mittels eines Haheriinges traten bisher insofern Schwierigkeiten auf, als zur Befestigung besondere Hilfsmittel, Schraubteile od.:dgl. erforderlich waren. Ein weiterer Nachteil :der bekannten Befestigungsweisen bestand darin, daß die verhältnismäßig kostspieligen Verbindungen während des Betriebes der elektrischen Maschinen locker wurden. Als Folgen 'dies Lockerwerdens :einzelner Teile der elektrischen Maschine hergaben sich Betriebsstörungen der verschiedensten Art. .The invention relates to an arrangement for fastening internal parts electrical machines by means of leg H.alteriiiges. When fastening internal parts by means of a Haherringes have so far encountered difficulties insofar as the attachment special tools, screw parts or the like. were required. Another disadvantage : the known methods of attachment consisted in the fact that the relatively expensive Connections became loose during operation of the electrical machines. as The consequences of this loosening up: individual parts of the electrical machine gave up Operational disruptions of various kinds..

Gemäß der vorliegenden Erfindung we'rden nun B,Hestigungen von Innenteilen elektrischer Maschinen mittels eines Halteringes dadurch wesentlich verbessert und vereinfacht, daß der seinen gadialschlitz aufweisende Haltering einenetwas größeren Durchmesser besitzt als eine zu seiner Aufnahme vorgesehene Eindrehung in :der zylindrischen öffnung des Gehäuses, in nie @er mittels an ihm oder an dem Gehäuse vorgesehener Abflachungen ein '-setzbar ist.According to the present invention, we'rden now B, fixings of internal parts electrical machines by means of a retaining ring thereby significantly improved and Simplified that the holding ring having its radial slot has a somewhat larger Diameter has as a recess provided for its reception in: the cylindrical Opening of the housing, in never @er means provided on it or on the housing Flats a 'can be inserted.

In der Zeichnung ist ein Ausführungsbeispiel dargestellt.An exemplary embodiment is shown in the drawing.

Fig. i zeigt einen Querschnitt durch einen Teil einer elektrischen Maschine mit seinem zur Befestigung des Lagerschildes :dienenden Haltering, und Fig. z veranschaulicht das Einsetzen des Halteringes.Fig. I shows a cross section through part of an electrical Machine with its retaining ring, which is used to attach the end shield, and Fig. Z illustrates the insertion of the retaining ring.

Zur Aufnahme dieses Halteringes besitzt .das zylindrische Gehäuse 5 auf seiner Innenseite eine Ringnut 6 vom der Breite b mit dein Durchmesser La. Durch diese Ringnut wird auf der Vorderseite des Gehäuseseine Rippe mit dem Durchmesser k. gebildet, gegen die .sich einerseits der Haltering i und andererseits der Lagerschild 8, die durch die Schrauben 7 miteinander verbunden werden, anlegen. Der Haltering i hat, wie aus Fig. 2 :ersichtlich, etwas größeren Durchmesser D, als die Ausdrehum;g 6 :des Gehäuses 'und ist mit einem radialen Schlitz -versehen, so, daß .er etwas federn kann. Dadurch setzt @er sich infolge Eigenfederung in der Ringnut 6 fest. Um den Haltering i an seinen Bestimmungsplatz bringen zu können, ist er, wie aus Fig. z ersichtlich, bei 3 reit einer Abflachung versehen. Der Haltering wird in der in Fig. z gezeigten Stellung in !einer durch die Achse :des Gehäuses hindurchgehenden Ebene eingeführt und :dann durch Drehen in :dieser Ebene verankert, sobald die Ab- flachung 3 aus :der Nut herausgedreht ist. Sodann wird der Halteräig i in eine Lage senkrecht zur Achse ,des Maschinengehäuses geschwenkt und damit n: die in Fig. i gezeigte Stellung gebracht, so, dä.ß der Lagerschild 8 an ihm angeschraubt werden kann. An Stelle einer Abflachung an dem Haltering i kann natürlich auch :eine entsprechende Ausneh@mung an der Rippe des Gehäuses 5 vorgesehen sein.To accommodate this retaining ring, the cylindrical housing 5 has on its inside an annular groove 6 of width b and diameter La. This annular groove creates a rib with the diameter k on the front of the housing. formed against which .sich on the one hand the retaining ring i and on the other hand the end shield 8, which are connected to one another by the screws 7, apply. As can be seen from FIG. 2, the retaining ring i has a slightly larger diameter D than the turning rotation; g 6: of the housing and is provided with a radial slot so that it can spring somewhat. As a result, it becomes stuck in the annular groove 6 due to its own springiness. In order to be able to bring the retaining ring i to its destination, it is provided with a flattening at 3, as can be seen from FIG. The retaining ring is in the z shown in Fig position in a through the axis: inserted therethrough of the housing plane, and:.! Then rotating in: anchored this level as soon as the waste 3 of flattening: the groove is rotated. The holder arm is then pivoted into a position perpendicular to the axis of the machine housing and thus brought to the position shown in FIG. Instead of a flattening on the retaining ring i, a corresponding recess can of course also be provided on the rib of the housing 5.
