Description

Stromwender für elektrische Maschinen, bei welchem auf einer Büchse aus Isolierstoff eine Kupferhülse festgebördelt ist, die durch Aufschneiden in der Längsrichtung in die einzelnen Stromwenderstege zerlegt ist. Es sind Stromwender (Kommutatoren) für elektrische Maschinen bekannt, bei denen auf einer Büchse aus Isolierstoff eine Kupferhülse festgebördelt ist, die durch Aufschneiden in der Längsrichtung in die einzelnen Stromwenderstege zerlegt ist. Diesen Stromwendern haftet der Mangel an; daß die Stege, die nur durch die Bördelung an ihren Enden auf der Isolierbüchse festgehalten werden, den im Betrieb auftretenden Beanspruchungen nicht standhalten, sondern locker werden und sich dann in der Umfangsrichtung verschieben.Current converter for electrical machines, in which on a can made of insulating material, a copper sleeve is crimped, which is cut in the Is divided longitudinally into the individual commutator bars. They are commutators (Commutators) known for electrical machines, where on a sleeve from Insulating material is crimped on a copper sleeve, which is cut open in the longitudinal direction is broken down into the individual commutator bars. The defect is liable to these commutators at; that the webs, which only through the flanging at their ends on the insulating sleeve are recorded, do not withstand the stresses occurring in operation, but become loose and then shift in the circumferential direction.

Um diesen Mangel zu beseitigen, werden gemäß der Erfindung die umgebördelten Enden der Kupferhülse durch Scheiben oder Ringe an die Stirnflächen der Isolierbüchse angepreßt.In order to eliminate this deficiency, the flanged are according to the invention Ends of the copper sleeve through washers or rings on the end faces of the insulating sleeve pressed on.

Auf der Zeichnung ist eine beispielsweise Ausführungsform der Erfindung dargestellt. Abb. i zeigt eine Stirnansicht des Stromwenders. Abb. 2 ist ein Schnitt nach der Linie A-13 in -Abb. i. In Abb. 3 ist eine Ansicht des Stromwenders dargestellt.The drawing shows an example embodiment of the invention shown. Fig. I shows a front view of the commutator. Fig. 2 is a section after the line A-13 in fig. i. Fig. 3 shows a view of the commutator.

Über eine aus Isolierstoff (Fiber o. dgl.) bestehende Büchse a ist in an sich bekannter Weise eine Kupferhülse b gebördelt. Durch die Bohrung der Büchse a ist eine Rohrniete c gesteckt, die von einer Isolation d umgeben ist. Durch den Nietvorgang werden die Ringe r und f erzeugt, welche die umgebördelten Ränder der Kupferhülse b fest gegen die Stirnfläche.a der Isolierbüchse a pressen. Die einzelnen Stromwenderstege werden durch Aufschneiden der Kupferhülse b in der Längsrichtung erzeugt. Die Rohrniete c wird zweckmäßig gleich als Nabe zur Befestigung des Stromwenders auf der Ankerwelle verwendet.About a made of insulating material (fiber o. The like.) Existing sleeve a is a copper sleeve b crimped in a manner known per se. Through the hole in the sleeve a tubular rivet c is inserted, which is surrounded by insulation d. Through the The riveting process produces the rings r and f, which are the flanged edges of the Press the copper sleeve b firmly against the end face a of the insulating sleeve a. The single ones Commutator bars are made by cutting open the copper sleeve b in the longitudinal direction generated. The tubular rivet c is expediently the same as a hub for fastening the commutator used on the armature shaft.

.Derartige Stromwender lassen sich besonders gut in kleinen Abmessungen herstellen und kommen daher in erster Linie für elektrische Kleinmaschinen in Betracht. Der Druck zum Anpressen der Kupferhülse an die Stirnflächen der Isolierbüchse kann auch auf andere Weise als durch N ietung erzeugt werden.Such commutators can be particularly good in small dimensions manufacture and are therefore primarily suitable for small electrical machines. The pressure for pressing the copper sleeve against the End faces of the The insulating sleeve can also be produced in other ways than riveting.
