Abstract

The invention relates to a hook-type commutator (24) comprising hooks (26) for the winding wires (20) of an armature winding. The hooks (26) are provided with longitudinal slots (28). A laser welding process is carried out through said longitudinal slots (28) in order to connect the winding wires (20) to the hooks (26). A genuine union of material is thus formed with a minimal, constant contact resistance.

Description

Hakenkommutatorhook commutator
Stand der TechnikState of the art
Die Erfindung geht aus von einem Hakenkommutator nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a hook commutator according to the preamble of patent claim 1.
Derartige beispielsweise in der DE 42 33 132 AI offenbarte Hakenkommutatoren weisen Haken für jeweils einen oder mehrere Wicklungsdrähte aus Kupferlackdraht einer Ankerwicklung auf. Die Verbindung der Haken und der Wicklungsdrähte erfolgt in der Regel im so genannten Hot-Staking- Verfahren, wie beispielsweise in der DE 31 31 117 AI beschrieben. Hierbei erfolgt ein Warmverpressen der Kupferlackdrähte unter den Haken, bei denen die Isolation des Kupferlackdrahtes abgebrannt und eine elektrische Verbindung zur Kommutatorlamelle hergestellt wird. Dieses Verfahren ist in hohem Maße von den Randbedingungen abhängig; insbesondere die Erweichungstemperatur der Isolation der Kupferlackdrähte, die Lage der Drähte unter den Haken sowie die Ausformung des Hakens und die Oberflächenbeschaffenheit erfordern ein peπnanentes Nachfuhren der Prozessparameter. Außerdem hat das Verfahren eine große thermische und mechanischen Einflusszone, wodurch sehr hohe Ansprüche an den Kommutatorunterbau einschließlich der Pressmassen gestellt werden.Such hook commutators, for example disclosed in DE 42 33 132 AI, have hooks for one or more winding wires made of enamelled copper wire of an armature winding. The connection of the hook and the winding wires is usually carried out in the so-called hot staking process, as described for example in DE 31 31 117 AI. Here, the enamelled copper wires are hot-pressed under the hooks, in which the insulation of the enamelled copper wire burns off and an electrical connection is made to the commutator bar. This process is highly dependent on the boundary conditions; In particular, the softening temperature of the insulation of the enamelled copper wires, the position of the wires under the hooks as well as the shape of the hooks and the surface quality require the process parameters to be tracked in a timely manner. In addition, the process has a large thermal and mechanical zone of influence, which places very high demands on the commutator base, including the molding compounds.
Vorteile der ErfindungAdvantages of the invention
Der erfϊndungsgemäße Hakenkommutator mit den Merkmalen des Patentanspruchs 1 hat den Vorteil, dass die mechanische Belastung von Draht und Kommutator geringer sind. Denn die Wärmeeinflusszone ist kleiner und außerdem kommt es zu einer echten stoffschlüssigen Verbindung, die minimale und konstante Übergangswiderstände zur Folge hat. Auch ist keine massive Verformung des Hakens erforderlich. Die geringere Abhängigkeit von Randbedingungen führt somit zu stabileren Fertigungsprozessen. Ferner sind sehr kurze Taktzeiten möglich, da die konventionelle Drahtverlegung mit zeitoptimierter Anhaktechnik benutzt werden kann. Besonders vorteilhaft ist der Einsatz bei Hakenkommutatoren, die nur geringe mechanische und thermische Belastungen, wie beispielsweise ein Kohlekommutator, zulassen.The hook commutator according to the invention with the features of claim 1 has the advantage that the mechanical load on the wire and commutator is lower. Because the heat affected zone is smaller and there is also a real material connection that has minimal and constant contact resistance Consequence. No massive deformation of the hook is required. The lower dependency on boundary conditions thus leads to more stable manufacturing processes. Furthermore, very short cycle times are possible, since conventional wire laying with time-optimized hooking technology can be used. It is particularly advantageous to use hook commutators that only allow low mechanical and thermal loads, such as a carbon commutator.
Hierzu ist vorgesehen, dass der Hakenkommutator mit wenigstens einem Haken für wenigstens einen Wicklungsdraht einer Ankerwicklung in dem Haken wenigstens eine sich durch den Haken erstreckende Ausnehmung aufweist.For this purpose it is provided that the hook commutator with at least one hook for at least one winding wire of an armature winding in the hook has at least one recess extending through the hook.
Vorzugsweise beträgt die Breite der Ausnehmung im Wesentlichen ein Drittel der Breite des Hakens und/oder die Breite der Ausnehmung entspricht im Wesentlichen der doppelten Dicke des Hakens. Dadurch ist der Haken mechanisch ausreichend stabil und die Ausnehrnung breit genug.The width of the recess is preferably essentially one third of the width of the hook and / or the width of the recess essentially corresponds to twice the thickness of the hook. As a result, the hook is mechanically stable enough and the opening is wide enough.
Die Ausnehrnung lässt sich besonders leicht herstellen, wenn sich die Ausnehrnung vom freien Ende des Hakens aus in Richtung des Ansatzes des Hakens an seiner Lamelle erstreckt. Es ist vorteilhaft, wenn sich die Ausnehmung im Wesentlichen bis zum Ansatz des Hakens erstreckt, da dadurch später alle Wicklungsdrähte für eine Laserbearbeitung direkt zugänglich sind. Dabei ist die Ausnehmung vorzugsweise als ein Längsschlitz ausgebildet, der sich im Wesentlichen parallel zur Längsachse des Kommutators erstreckt, da sich die notwendige Länge leicht einstellen lässt.The cutout can be produced particularly easily if the cutout extends from the free end of the hook in the direction of the attachment of the hook to its lamella. It is advantageous if the recess extends essentially up to the attachment of the hook, since this later makes all winding wires directly accessible for laser processing. The recess is preferably designed as a longitudinal slot which extends essentially parallel to the longitudinal axis of the commutator, since the necessary length can be easily adjusted.
Bei einem A-nker für eine elektrische Maschine mit einem derartigen Hakenkommutator werden Schwachstellen an den Hakenkanten vermieden. Dadurch wird die Gefahr von Schwingungsbrüchen der Drähte bei einer elektrischen Maschine mit einem derartigen Anker beträchtlich vermindert.With an armature for an electrical machine with such a hook commutator, weak points on the hook edges are avoided. This considerably reduces the risk of vibration breakage of the wires in an electrical machine with such an armature.
Bei einem Verfahren zur Herstellung eines Ankers mit einem derartigen Kommutator lässt sich die Verbindung der Ankerwicklungen mit den Haken des Kommutators mittels Laserschweißung durch die Ausnehmung hindurch vornehmen. Dies wirkt sich vorteilhaft auf die Prozesssicherheit aus, da das Hot-Staking- Verfahren vermieden wird. Weitere Vorteile und vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen und der Beschreibung.In a method for producing an armature with such a commutator, the armature windings can be connected to the hooks of the commutator by means of laser welding through the recess. This has an advantageous effect on process reliability, since the hot staking process is avoided. Further advantages and advantageous further developments result from the subclaims and the description.
Zeichnungdrawing
Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigen Figur 1 eine stark vereinfachte elektrische Maschine in einem Längsschnitt, Figur 2 einen Teil eines Kommutators, Figuren 3-5 die Herstellungsschritte einer Verbindung eines Kommutatorhakens mit Wicklungsdrähten.An embodiment is shown in the drawing and explained in more detail in the following description. FIG. 1 shows a greatly simplified electrical machine in a longitudinal section, FIG. 2 shows a part of a commutator, FIGS. 3-5 show the manufacturing steps for connecting a commutator hook to winding wires.
Beschreibung des AusführungsbeispielsDescription of the embodiment
Figur 1 zeigt einen als Gleichstrommotor ausgebildeten Elektromotor 10. Ein derartiger Elektromotor 10 wird vorzugsweise in Kraftfahrzeugen als Fensterheber, Wischerantrieb oder dergleichen verwendet.FIG. 1 shows an electric motor 10 designed as a direct current motor. Such an electric motor 10 is preferably used in motor vehicles as a window regulator, wiper drive or the like.
Im Gehäuse 12 ist die Welle 14 eines Ankers 16 drehbar um eine Rotationsachse 18 gelagert. Als Kupferlackdrähte ausgebildete Wicklungsdrähte 20 der auf dem Blechpaket 22 des Ankers 16 angeordneten Ankerwicklung sind mit einem Hakenkommutator 24 verbunden, auf dem nicht gezeigte Bürsten schleifen.The shaft 14 of an armature 16 is rotatably mounted in the housing 12 about an axis of rotation 18. Coil wires 20 designed as enamelled copper wires of the armature winding arranged on the laminated core 22 of the armature 16 are connected to a hook commutator 24 on which brushes, not shown, grind.
In der Figur 2 ist ein Ausschnitt des Hakenkommutators 20 in einer perspektivischen Ansicht im Bereich eines Hakens 26 gezeigt. Der doppelt um den Haken 26 gelegte Wicklungsdraht 20 ist dabei aufgetrennt dargestellt.FIG. 2 shows a detail of the hook commutator 20 in a perspective view in the area of a hook 26. The winding wire 20 placed twice around the hook 26 is shown separated.
Der Haken 26 umfasst zwei durch einen Längsschlitz 28 getrennte Flügel 30 und hat eine Länge 31. Vorzugsweise verlaufen die Flügel 30 im weseαtlichen parallel zueinander und zur Längsachse des Hakenkommutators 20, die mit der Rotationsachse 18 (Figur 1) übereinstimmt. Die Flügel 30 sind über einen bogenförmigen Ansatz 32, der vorzugsweise im Wesentlichen einen Halbkreis beschreibt-, mit der dem Haken 26 zugeordneten Lamelle 34 verbunden. Durch die Anordnung der Flügel 30 verläuft auch der Längsschlitz 28 im Wesentlichen parallel zur Längsachse des Kommutators 20.The hook 26 comprises two wings 30 separated by a longitudinal slot 28 and has a length 31. The wings 30 preferably run essentially parallel to one another and to the longitudinal axis of the hook commutator 20, which corresponds to the axis of rotation 18 (FIG. 1). The wings 30 are connected to the lamella 34 assigned to the hook 26 via an arcuate extension 32, which preferably essentially describes a semicircle. Due to the arrangement of the wings 30, the longitudinal slot 28 also runs essentially parallel to the longitudinal axis of the commutator 20.
Die Breite 36 des Längsschlitzes 28 beträgt im Wesentlichen ein Drittel der Breite 38 des Hakens 26. Es ist alternativ oder zusätzlich möglich, dass die Breite 36 des Längsschlitzes 28 im Wesentlichen der doppelten Dicke 40 des Hakens 26 entspricht. Diese Angaben beinhalten natürlich Abweichungen, insbesondere fertigungsbedingte Abweichungen, im Bereich von einigen Zehαtelmillimetern bis Millimetern.The width 36 of the longitudinal slot 28 is essentially one third of the width 38 of the hook 26. It is alternatively or additionally possible that the width 36 of the Longitudinal slot 28 substantially corresponds to twice the thickness 40 of the hook 26. This information naturally includes deviations, in particular production-related deviations, in the range from a few tenths of a millimeter to millimeters.
Zwar erstreckt sich der Längsschlitz 28 ausgehend vom freien Ende 41 des Hakens 26 aus in Richtung des Ansatzes 32 des Hakens 26. Es ist aber auch denkbar, dass der Längsschlitz 28 sich nicht vom freien Ende des Hakens 26 unter Bildung zweier Flügel 30 erstreckt, sondern das dass freie Ende 41 geschlossen ist. Auch muss sich der Längsschlitz 28 nicht, wie gezeigt, im Wesentlichen bis zum Ansatz 32 des Hakens 26 erstrecken, sondern kann auch ein Stück davon entfernt enden. Durch die Erstreckung bis zum Ansatz 32 jedoch sind die sich unter den Flügeln 30 befindenden Wicklungsdrähten von außen leichter zugänglich.The longitudinal slot 28 extends from the free end 41 of the hook 26 in the direction of the shoulder 32 of the hook 26. It is also conceivable that the longitudinal slot 28 does not extend from the free end of the hook 26 to form two wings 30, but that the free end 41 is closed. Also, as shown, the longitudinal slot 28 does not have to extend essentially as far as the extension 32 of the hook 26, but can also end a distance away from it. Due to the extension to the neck 32, however, the winding wires located under the wings 30 are more easily accessible from the outside.
Statt eines Längsschlitzes 28, d.h. eines Schlitzes, der sich in Längsrichtung des Hakens 26 bzw. der Flügel 30 erstreckt, kann auch eine andere Form einer sich quer durch den Haken 26 erstreckenden Ausnehmung vorgesehen sind, beispielsweise eine runde, elliptische oder sonstige Ausnehmung.Instead of a longitudinal slot 28, i.e. of a slot which extends in the longitudinal direction of the hook 26 or the wing 30, another shape of a recess extending transversely through the hook 26 can also be provided, for example a round, elliptical or other recess.
Wie aus der Figur 3 hervorgeht, wird bei der Herstellung des Ankers 16 zunächst der Wicklungsdraht 20 zweimal bzw. so oft wie notwendig, zum Beispiel im sogenannten „Flyer- Wickelverfahren" um den Haken 26 des Hakenkommutators 24 gelegt. Anschließend wird, wie in der Figur 4 verdeutlicht, der Haken 26 mit einem Stempel 42 an den Kommutator 24 gedrückt und damit zugebogen. Dadurch wird der Wicklungsdraht 20 mechanisch fixiert. Dann wird, wie in Figur 5 gezeigt, der Wicklungsdraht 20 durch einen durch den Längsschlitz 28 gerichteten Laserstrahl 43, der von einer Laserquelle 44 erzeugt wird, aufgeschmolzen. Dabei werden auch Teile des Hakens 26, d. h. die Innenbereiche der Flügel 30 gegebenenfalls des Ansatzes 32 aufgeschmolzen. Dadurch entsteht eine echte metallische Verbindung des Kupfers des Haken 26 und des Kupfers des Wicklungsdrahtes 20 mit geringen und gut reproduzierbaren Übergangswiderständen. Durch das Aufschmelzen entstandene mechanische Schwachstellen des Wicklungsdrahtes 20 befinden sich mittig unter dem Haken 26. Die Bereiche an den Außenkanten des Hakens 26 Werte nicht geschwächt. As can be seen from FIG. 3, when the armature 16 is produced, the winding wire 20 is first placed twice or as often as necessary, for example in the so-called “flyer winding method”, around the hook 26 of the hook commutator 24. Then, as in FIG 4 illustrates that the hook 26 is pressed against the commutator 24 with a plunger 42 and is thus bent in. The winding wire 20 is thereby mechanically fixed. Then, as shown in FIG. 5, the winding wire 20 is moved by a laser beam 43 directed through the longitudinal slot 28. which is generated by a laser source 44. Parts of the hook 26, that is to say the inner regions of the wings 30 and, if applicable, of the attachment 32, are also melted on Easily reproducible contact resistances. Mechanical weak points in the winding wire caused by the melting htes 20 are located centrally under the hook 26. The areas on the outer edges of the hook 26 values are not weakened.
