Description
Die Erfindung geht aus von einem Kontaktelementhalter zum elektrischen Kontaktieren eines Rotors, insbesondere von einem Bürstenhalter für Kommutator- oder Schleifringmaschinen, nach dem Oberbegriff des Anspruchs 1.The invention relates to a contact element holder for electrically contacting a rotor, in particular a brush holder for commutator or slip ring machines, according to the preamble of claim 1.
Ein solcher Kontaktelementhalter ist bekannt aus
Insbesondere Kommutatorbürsten von Kommutatormaschinen, z.B. Gleichstromkleinmotoren, verursachen aufgrund von Kommutatorunrundheiten, Sprüngen beim Übergang von der einen zur anderen Kommutatorlamelle u.ä. Laufgeräusche, die über den Bürstenträger auf das Maschinengehäuse übertragen und von diesem abgestrahlt werden. Um diese Laufgeräusche zu reduzieren, werden geräuschentkoppelte Bürstenhalter verwendet.In particular, commutator brushes of commutator machines, e.g. DC small motors, cause due to Kommutatorunrundheiten, jumps in the transition from one to another Kommutatorlamelle u.ä. Operating noise that is transmitted to the machine housing via the brush holder and radiated by the latter. In order to reduce these running noises, noise-decoupled brush holders are used.
Um eine qualitativ gute Kommutierung sicherzustellen, ist es wichtig, daß der Bürstenhalter zentrisch zur Kommutatorachse liegt. Abweichungen davon erzeugen Unsymmetrien bei der Bestromung, und die dadurch erzeugten Kräfte sind wiederum Ursachen von Geräuschen. Bei dem geräuschentkoppelten Bürstenhalter muß eine gewisse Flexibilität der Bürstenköcher gegenüber dem Bürstenträger in Kauf genommen werden, so daß durch die mit dieser Flexibilität verknüpfte Ungenauigkeit der zentrischen Lage der Kommutatorbürsten sich die Kommutierungsqualität verschlechtert.To ensure good quality commutation, it is important that the brush holder is centered to the commutator axis. Deviations from this cause imbalances in the energization, and the forces generated by them are again Causes of noise. In the noise-decoupled brush holder, a certain flexibility of the brush holder with respect to the brush holder must be taken into account, so that deteriorates the commutation by the associated with this flexibility inaccuracy of the centric position of the commutator brushes.
Bei einem bekannten, geräuschentkoppelten Bürstenhalter (
Der erfindungsgemäße Kontaktelementhalter mit den Merkmalen des Anspruchs 1 hat den Vorteil, daß eine rotatorische Entkopplung der Köcher um die Rotorachse ohne zusätzliche Freiheitsgrade translatorischer oder rotatorischer Art erzielt wird und dadurch in Anwendung bei Kommutatormaschinen die für eine gute Kommutierung erforderliche, zentrierte Position der Kommutatorbürsten gegenüber einem nicht geräuschentkoppelten, starren Bürstenhalter.nicht verschlechtert wird. Die für die Bürstengeräusche verantwortlichen Reibwertschwankungen zwischen Kommutatorlamellen und Kommutatorbürsten, bewirken ausschließlich eine rotatorische Verdrehung der Köcher und beeinflussen dadurch die zentrierte Lage der Kommutatorbürsten nicht. Durch Veränderung von Geometrie, Position und Anzahl der Entkopplungselemente ist der Kontaktelementhalter gezielt abstimmbar und kann damit an unterschiedliche Anwendungsfälle Maschinen recht einfach angepaßt werden.The contact element holder according to the invention with the features of claim 1 has the advantage that a rotational decoupling of the quiver around the rotor axis without additional degrees of translational or rotational nature is achieved and thereby in use in commutator required for a good commutation, centered position of the commutator over a not noise-decoupled, rigid brush holder.not deteriorated. The responsible for the brush noise Reibwertschwankungen between commutator and commutator, cause exclusively a rotatory rotation of the quiver and thus do not influence the centered position of the commutator brushes. By changing the geometry, position and number of decoupling elements of the contact element holder is specifically tuned and can therefore be adapted quite easily to different applications machines.
Durch die in den weiteren Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Anspruch 1 angegebenen Kontaktelementhalters möglich.The measures listed in the further claims advantageous refinements and improvements of claim 1 contact element holder are possible.
Der erfindungsgemäße Kontaktelementhalter läßt sich konstruktiv sehr einfach dadurch realisieren, daß gemäß einer bevorzugten Ausführungsform der Erfindung mindestens drei Entkopplungselemente vorgesehen sind und jedes Entkopplungselement nur einen Freiheitsgrad aufweist, wobei die Entkopplungselemente so zwischen Träger und Köcher angeordnet sind, daß der Freiheitsgrad jedes Entkopplungselements in Tangentialrichtung zum Rotor verläuft.The contact element holder according to the invention can be realized structurally very simple in that according to a preferred embodiment of the invention, at least three decoupling elements are provided and each decoupling element has only one degree of freedom, wherein the decoupling elements are arranged between the carrier and quiver so that the degree of freedom of each decoupling element in the tangential direction Rotor runs.
Gemäß einer bevorzugten Ausführungsform der Erfindung sind die Entkopplungselemente um vorzugsweise gleiche Drehwinkel in Umfangsrichtung gegeneinander versetzt, also sternförmig angeordnet.According to a preferred embodiment of the invention, the decoupling elements are offset by preferably the same rotation angle in the circumferential direction against each other, so arranged in a star shape.
Gemäß einer bevorzugten Ausführungsform der Erfindung sind die Köcher auf einem Zwischenträger angeordnet und Träger und Zwischenträger durch die Entkopplungselemente miteinander verbunden.According to a preferred embodiment of the invention, the quivers are arranged on an intermediate carrier and carrier and intermediate carrier are interconnected by the decoupling elements.
Träger und Zwischenträger sind dabei als Isolierstoffplatten ausgeführt, die in einer gemeinsamen Ebene liegen, und die elastischen Stege erstrecken sich rechtwinklig zu den Platten. Durch diese konstruktive Ausführung mit "stehenden Entkopplungselementen" hat der Kontaktelementhalter einen geringen Platzbedarf, was vorteilhaft für die Unterbringung zusätzlicher Entstörelemente ist. Außerdem liegen die Entkopplungselemente beim Spritzen des einstückigen Kontaktelementhalters in Entformungsrichtung, so daß im Spritzwerkzeug keine zusätzlichen Querschieber erforderlich sind.Carrier and intermediate carrier are designed as Isolierstoffplatten, which lie in a common plane, and the elastic webs extend at right angles to the plates. This constructive design with "standing decoupling elements" of the contact element holder has a small footprint, which is advantageous for the accommodation of additional suppression elements. In addition, the decoupling elements are when spraying the one-piece contact element holder in Entformungsrichtung, so that no additional cross slide are required in the injection mold.

Für den zweipolig ausgeführten Gleichstromkleinmotor hat der Bürstenhalter zwei Kommutatorbürsten 16, die jeweils in einem sich in Richtung der Durchtrittsöffung 15 erstreckenden Bürstenköcher 17 axial verschieblich aufgenommen sind und im montierten Zustand mittels hier nicht dargestellter Bürstenandruckfedern auf den Kommutator aufgedrückt werden. Die elektrischen Anschlußlitzen der Kommutatorbürsten 16 sind mit 18 bezeichnet. Die Bürstenköcher 17 sind auf dem Zwischenträger 13 befestigt. Hierzu sind am Zwischenträger 13 zwei abstrebende Arme 131 vorgesehen, die mit Spiel in entsprechenden, seitlichen Verlängerungen 121 der Aussparung 12 einliegen. Die Bürstenköcher 17 sind aus Metall gefertigt und auf den Armen 131 befestigt. In einer alternativen Ausführungsform der Erfindung können die Bürstenköcher 17 auch aus Isolierstoff gefertigt werden und werden dann einstückig mit der Isolierstoffplatte des Zwischenträgers 13 durch Spritzen hergestellt, so daß die Arme 131 entfallen. Die vier Entkopplungselemente 14 sind um gleiche Umfangswinkel gegeneinander versetzt sternförmig um die Durchtrittsöffnung 12 im Zwischenträger 13 angeordnet und sind einerseits zwischen den Bürstenköchern 17 an dem Zwischenträger 13 und andererseits an dem Träger 11 festgelegt. Jedes Entkopplungselement 14 weist nur einen Freiheitsgrad auf und ist so angeordnet, daß dieser Freiheitsgrad in Tangentialrichtung zum Kommutator, also zu der den Kommutator aufnehmenden Durchtrittsöffnung 15, verläuft, wobei selbstverständlich der Bürstenhalter so im Motorgehäuse montiert ist, daß die Achse der Durchtrittsöffnung 15 im Zwischenträger 13 mit der Kommutatorachse zusammenfällt. Durch die sternförmige Anordnung der Entkopplungselemente 14 mit tangential gerichtetem Freiheitsgrad vermag der Zwischenträger 13 mit den darauf befestigten Bürstenköchern 17 ausschließlich einen begrenzten, rotatorischen Schwenkweg um den Kommutator auszuführen, so daß die auf den Kommutator sich aufpressenden Kommutatorbürsten 16 rotatorisch entkoppelt sind. Weitere Freiheitsgrade, nämlich zwei rotatorische und drei translatorische, sind nicht vorhanden oder sind vernachlässigbar.For the two-pole DC motor, the brush holder has two
