Description

  

  Welle für elektrische Maschinen, insbesondere Lichtmaschinen  auf Kraftfahrzeugen oder Flugzeugen.    Die Erfindung bezieht sich auf eine Welle  für elektrische Maschinen, insbesondere Licht  maschinen auf Kraftfahrzeugen oder Flug  zeugen. Der Zweck der Erfindung ist, das  Gewicht der elektrischen Maschine herunter  zusetzen. Beim Betrieb von elektrischen  Maschinen, z. B. Lichtmaschinen auf Flug  zeugen kommen häufig starke Beschleuni  gungen oder auch Verzögerungen vor, die  eine so starke Beanspruchung der Maschinen  welle bedingen, dass die Verwendung von  Leichtmetallen auf Schwierigkeiten stösst.  Um Leichtmetall verwenden zu können,     wird     gemäss der Erfindung als Welle eine mit  einem elastischen Antriebsglied verbundene  und die umlaufenden Maschinenteile tragende  Hülse aus Leichtmetall vorgesehen.  



  In der Abbildung ist eine Ausführungs  form der Erfindung im Schnitt dargestellt.  <I>a</I> ist der Anker und<I>b</I> der Stromwender einer    Lichtmaschine. Diese beiden sind auf einer  einen Teil der Welle bildenden Hülse c aus  Duraluminium aufgesetzt. Die .Hülse ist an  beiden Enden in den Kugellagern d gelagert.  In der Hülse befindet sich eine als Torsions  stab wirkende Torsionswelle e, die mit der  Hülse an einem Ende fest verbunden ist und  freischwebend sich durch die ganze Hülse  erstreckt. Das über die Hülse vorstehende  Ende der Torsionswelle ist als Kupplungs  glied f ausgebildet.  



  Die Torsionswelle schwächt die bei plötz  lichen Beschleunigungen oder Verzögerungen  auftretenden Drehmomentstösse ab, so dass  die an der Hülse auftretenden Beanspruchun  gen ihre Spitzenwerte verlieren.



  Shaft for electrical machines, in particular alternators on motor vehicles or aircraft. The invention relates to a shaft for electrical machines, in particular light machines on motor vehicles or aircraft testify. The purpose of the invention is to reduce the weight of the electrical machine. When operating electrical machines, e.g. B. alternators on flight testify often strong accelerations or delays that cause such a heavy load on the machine shaft that the use of light metals encounters difficulties. In order to be able to use light metal, according to the invention a sleeve made of light metal is provided as the shaft, which is connected to an elastic drive member and carries the rotating machine parts.



  In the figure, an embodiment of the invention is shown in section. <I> a </I> is the armature and <I> b </I> the commutator of an alternator. These two are placed on a sleeve c made of duraluminium which forms part of the shaft. The sleeve is mounted at both ends in the ball bearings d. In the sleeve there is a torsion shaft e which acts as a torsion bar and which is fixedly connected to the sleeve at one end and which extends freely through the entire sleeve. The protruding over the sleeve end of the torsion shaft is designed as a coupling member f.



  The torsion shaft weakens the torque surges that occur in the event of sudden accelerations or decelerations, so that the stresses that occur on the sleeve lose their peak values.
