Description
Die Erfindung betrifft ein Verfahren zum Herstellen eines Kommutatorringes für einen Kommutator mit den im Anspruch 1 genannten Merkmalen.The The invention relates to a method for producing a commutator ring for one Commutator with the features mentioned in claim 1.
Stand der TechnikState of the art
Es ist bekannt, Kommutatorringe aus einem zuvor geprägten Bandmaterial für sogenannte Rollkommutatoren herzustellen. Hierbei wird ein gegebenenfalls profiliertes Endlosband, dessen Breite der späteren axialen Länge des Kommutators entspricht, quer zur Bewegungsrichtung des Bandes mittels eines Formwerkzeugs mit Nuten versehen, so daß lediglich noch über Stege verbundene Lamellen entstehen. Entsprechend der Lamellenanzahl eines Kommutatorrings wird eine entspre chende Anzahl von Lamellen von dem fortlaufenden, jetzt geformten Band abgetrennt und zu dem Kommutatorring geschlossen. Zur Stabilisierung des Kommutatorrings und Isolierung der einzelnen Lamellen untereinander wird der Kommutatorring zumeist zusammen mit einer metallischen Nabe in eine Isolierstoffmasse eingebettet.It is known commutator rings from a previously embossed strip material for so-called Roll commutators produce. This is an optionally profiled Endless band whose width is the later axial length of the commutator, transverse to the direction of movement of the tape provided with grooves by means of a molding tool so that only still over Webs connected lamellae arise. According to the number of slats a commutator ring is a corre sponding number of fins separated from the continuous, now formed band and to the Commutator ring closed. To stabilize the commutator ring and Insulation of the individual fins among themselves becomes the commutator ring usually together with a metallic hub in a Isolierstoffmasse embedded.
Um beim späteren bestimmungsgemäßen Einsatz des Kommutatorrings ein axiales Verschieben der Lamellen zu verhindern, ist es bekannt, die Lamellen mit Befestigungsmitteln zu versehen, die in die Isolierstoffmasse eingreifen.Around later intended use the commutator ring to prevent axial displacement of the slats, it is known to provide the lamellae with fastening means, which engage in the insulating material.

Der Erfindung liegt die Aufgabe zugrunde, ein einfaches Verfahren zur Herstellung von Kommutatorlamellen, die eine sichere Verankerung im Isolierstoffkörper gegen axiale und radiale Kräfte besitzen, anzugeben.Of the Invention is based on the object, a simple method for Manufacture of commutator blades that provide a secure anchorage in the insulating body against axial and radial forces have to indicate.
Diese Aufgabe wird mit einem Verfahren gemäß Anspruch 1 gelöst.These The object is achieved by a method according to claim 1.
Vorteile der ErfindungAdvantages of invention
Das erfindungsgemäße Verfahren mit den im Anspruch 1 genannten Merkmalen bietet demgegenüber den Vorteil, daß unter Beibehaltung der nutzbaren Lamellenstärke eine sichere Verankerung der Lamellen in der Isolierung möglich ist. Dadurch, daß die Befestigungsmittel als in Axialrichtung der Lamellen verlaufendes, unterbrochenes Schwalbenschwanzprofil ausgebildet werden, ist es vorteilhaft möglich, mittels eines einzigen, einfach ausführbaren Verfahrensschrittes den Lamellen eine derartige Formgebung zu geben, daß gleichzeitig eine sichere Verankerung der Lamellen gegen radiale und/oder axiale Kräfte in der Isolierung möglich wird. Insbesondere durch das in Axialrichtung unterbrochene Schwalbenschwanzprofil werden in Axialrichtung verlaufende Hinterschneidungen zwischen den Befestigungsmitteln der Lamellen und dem Isoliermaterial möglich, die eine Verschiebung in axialer Richtung verhindern.The inventive method with the features mentioned in claim 1 offers the other hand Advantage that under Maintaining the usable lamella strength a secure anchorage slats in the insulation possible is. Due to the fact that the fastening means as in the axial direction of the slats extending, interrupted dovetail profile be formed, it is advantageously possible by means of a single, easy to execute Process step to give the lamellae such a shape, that at the same time a secure anchoring of the slats against radial and / or axial forces in the Isolation possible becomes. In particular, by the broken in the axial direction dovetail profile are in the axial direction undercuts between the fastening means of the slats and the insulating material possible, the prevent a shift in the axial direction.
Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den in den Unteransprüchen genannten Merkmalen.advantageous Embodiments of the invention will become apparent from the mentioned in the dependent claims Features.
