In jedem Fall wird durch das partielle Trennen eine Kontaktzunge nur teilweise vom Material des Bürstenelements getrennt, so dass eine Verbindung zwischen dem Körper des Bürstenelements und der Kontaktzunge bestehen bleibt beziehungsweise ein entsprechender Verbindungssteg existiert.In particular, the brush element has a body and comprises the contact tongue for transmitting the electrical currents or signals. The partial separation can be carried out, for example, by cutting, for example by means of a punching or a laser cutting process or also - in particular with comparatively thin-walled brush elements - by an etching process. In any case, the partial separation of a contact tongue is only partially separated from the material of the brush element, so that a connection between the body of the brush member and the contact tongue remains or a corresponding connecting web exists.
Zusätzlich kann auch der Schleifring eine Kontaktzunge zum Übertragen der elektrischen Ströme oder Signale aufweisen, wobei dann die Kontaktzunge des Bürstenelements axial versetzt zur Kontaktzunge des Schleifrings angeordnet ist.In addition, the slip ring may also have a contact tongue for transmitting the electrical currents or signals, in which case the contact tongue of the brush element is arranged axially offset from the contact tongue of the slip ring.

In Vorteilhafterweise ist das Verhältnis der Länge L zur Breite w größer als 3, insbesondere größer als 4.According to a development of the invention, the at least one contact tongue has a width w in the axial direction along the bending line and a length L in the circumferential direction (relative to the grinding path), wherein the ratio of length L to width w is greater than 2 (L / w > 2). Advantageously, the ratio of the length L to the width w is greater than 3, in particular greater than 4.
Mit Vorteil ist das Bürstenelement als einstückiges Stanz-Biege-Teil ausgestaltet. Alternativ kann das Bürstenelement auch statt mit Hilfe eines Stanzprozesses durch einen Laserschneidprozess oder - insbesondere bei vergleichsweise dünnwandigen Bürstenelementen - durch einen Ätzprozess hergestellt werden.Advantageously, the brush element is designed as a one-piece stamped and bent part. Alternatively, the brush element may also be produced by an etching process instead of with the aid of a stamping process by a laser cutting process or, in particular with comparatively thin-walled brush elements.
Das Bürstenelement kann weiterhin aus einem mehrschichtigen Metallstreifen hergestellt sein. Alternativ oder ergänzend kann der Schleifring aus einem mehrschichtigen Metallstreifen hergestellt sein. Insbesondere kann ein entsprechender Metallstreifen eine Außenschicht aufweisen, die ein Edelmetall umfasst, beispielsweise Gold oder Silber oder eine Legierung, die Gold oder Silber enthält.The brush element may further be made of a multilayer metal strip.

In particular, a corresponding metal strip may have an outer layer which is a noble metal includes, for example, gold or silver or an alloy containing gold or silver.
Mit Vorteil weist die Schleifringeinheit mehrere konzentrische Schleifringe und mehrere konzentrische Bürstenelemente auf. Insbesondere kann die Schleifringeinheit zumindest zwei konzentrische Schleifringe und zumindest zwei konzentrische Bürstenelemente aufweisen, die in einer geometrischen Ebene angeordnet sind, welche orthogonal zur Achse orientiert ist. Dementsprechend wird in diesem Fall ein erster Schleifring von einem ersten Bürstenelement elektrisch kontaktiert und ein zweiter Schleifring von einem zweiten Bürstenelement elektrisch kontaktiert.Advantageously, the slip ring unit has a plurality of concentric slip rings and a plurality of concentric brush elements. In particular, the slip ring unit may comprise at least two concentric slip rings and at least two concentric brush elements arranged in a geometric plane which is oriented orthogonal to the axis. Accordingly, in this case a first slip ring is electrically contacted by a first brush element and a second slip ring is electrically contacted by a second brush element.
Sofern die erste Bauteilgruppe mehrere Bürstenelemente aufweist und die zweite Bauteilgruppe mehrere umlaufende Schleifringe, weisen die Schleifringe insbesondere unterschiedliche Durchmesser auf und sind mit radialem Abstand konzentrisch zueinander und insbesondere jeweils radial gegenüber liegend zueinander, insbesondere mit axialer Überlappung, angeordnet.If the first component group has a plurality of brush elements and the second component group has several circumferential slip rings, the slip rings have, in particular, different diameters and are arranged at a radial distance concentric with each other and in particular in each case radially opposite one another, in particular with axial overlap.

Alternatively, the slideways may be arranged in parallel geometric planes which intersect the axis orthogonally.
Die Bürstenelemente können allesamt aus geometrisch identischen Metallstreifen hergestellt sein, so dass also die Kontaktzungen in Umfangsrichtung jeweils den gleichen Abstand aufweisen. Folglich weisen die jeweiligen konzentrischen Bürstenelemente der Schleifringeinheit, die insbesondere unterschiedliche Durchmesser aufweisen, pro Bürstenelement eine unterschiedliche Anzahl von Kontaktzungen auf. Ein erstes Bürstenelement weist demnach gegenüber einem zum ersten Bürstenelement konzentrischen zweiten Bürstenelement eine unterschiedliche Anzahl von Kontaktzungen auf.The brush elements can all be made of geometrically identical metal strips, so that therefore the contact tongues in the circumferential direction each have the same distance. Consequently, the respective concentric brush elements of the slip ring unit, which in particular have different diameters, have a different number of contact tongues per brush element. A first brush element accordingly opposite to a concentric with the first brush element second brush element a different number of contact tongues.

Die erste Bauteilgruppe 1 weist einen ersten Halter 1.4 auf, welcher beispielsweise als ein Kunststoffbauteil ausgestaltet ist. Der erste Halter 1.4 weist ein erstes, zweites und drittes in axialer Richtung hervorspringendes Element 1.41, 1.42, 1.43 auf, die im vorgestellten Ausführungsbeispiel als konzentrische umlaufende Stege ausgestaltet sind. Diese hervorspringenden Elemente 1.41, 1.42, 1.43 sind einstückig am ersten Halter 1.4 angeformt. Der erste Halter 1.4 umfasst zudem Kavitäten 1.45 (
Weiterhin umfasst die erste Bauteilgruppe 1 ein erstes, ein zweites und ein (innen liegendes) drittes Bürstenelement 1.1, 1.2, 1.3, wobei die Bürstenelemente 1.1, 1.2, 1.3 im vorgestellten Ausführungsbeispiel als mehrschichtige Blechstreifen ausgebildet sind. Die als Blechstreifen, insbesondere aus einem mit einer Silberschicht versehenen Messingkern, ausgebildeten Bürstenelemente 1.1, 1.2, 1.3 haben vor ihrer Fertigstellung zunächst eine ebene Geometrie und weisen jeweils mehrere Laschen 1.11 (siehe die
Die Bürstenelemente 1.1, 1.2, 1.3 werden mit Kontaktzungen 1.13, 1.23, 1.33 versehen, die durch partielles Trennen beziehungsweise Einschneiden und Ausbiegen erzeugt werden. Demnach wird das jeweilige als Blechstreifen ausgebildete Bürstenelement 1.1, 1.2, 1.3 nur teilweise getrennt, insbesondere gestanzt, so dass eine Verbindung des Körpers 1.12, 1.22, 1.32 des Bürstenelements 1.1, 1.2, 1.3 zur Kontaktzunge 1.13, 1.23, 1.33 bestehen bleibt. Darauffolgend wird die Kontaktzunge 1.13, 1.23, 1.33 um eine Biegeline B ausgebogen beziehungsweise geprägt. Das erste Bürstenelement 1.1, das zweite Bürstenelement 1.2 und das dritte Bürstenelement 1.3 sind demzufolge jeweils als einstückige Stanz-Biege-Teile ausgestaltet. Das Biegen beziehungsweise Prägen wird in einer Weise vorgenommen, dass am Ende der Kontaktzungen 1.13, 1.23, 1.33 konvexe Flächen entstehen.The brush elements 1.1, 1.2, 1.3 are provided with contact tongues 1.13, 1.23, 1.33, which are produced by partial separation or cutting and bending. Accordingly, the respective formed as a sheet metal strip brush element 1.1, 1.2, 1.3 only partially separated, in particular stamped, so that a compound of the body 1.12, 1.22, 1.32 of the brush element 1.1, 1.2, 1.3 to the contact tongue 1.13, 1.23, 1.33 remains. Subsequently, the contact tongue 1.13, 1.23, 1.33 is bent or embossed by a bending line B. The first brush element 1.1, the second brush element 1.2 and the third brush element 1.3 are therefore each designed as one-piece stamped and bent parts. The bending or embossing is carried out in such a way that at the end of the contact tongues 1.13, 1.23, 1.33 convex surfaces arise.
Die Bürstenelemente 1.1, 1.2, 1.3 werden nun zu konzentrischen Ringen mit jeweils unterschiedlichen Durchmessern um die Achse A gebogen. Bezüglich der hervorspringenden Elemente 1.41, 1.42, 1.43 beziehungsweise der Stege werden die Bürstenelemente 1.1, 1.2, 1.3 im Zuge der weiteren Montage der ersten Bauteilgruppe 1 jeweils radial innen liegend angeordnet, wobei die Laschen 1.11 durch in Umfangsrichtung versetzt angeordnete, axial durchgehende Schlitze 1.44 (
Die axial hervorspringenden Elemente 1.41, 1.42, 1.43 beziehungsweise konzentrischen Stege dienen zur Abstützung in radialer Richtung eines jeweiligen Bürstenelements 1.1, 1.2, 1.3. Die Kontaktzungen 1.13, 1.23, 1.33 sind radial nach innen zur Achse A hin ausgebogen, wobei die Biegeline B parallel zur Achse A verläuft.The axially projecting elements 1.41, 1.42, 1.43 or concentric webs serve to support in the radial direction of a respective brush element 1.1, 1.2, 1.3. The contact tongues 1.13, 1.23, 1.33 are bent radially inwards towards the axis A, wherein the bending line B extends parallel to the axis A.
Die zweite Bauteilgruppe 2 weist einen zweiten Halter 2.4 auf, welcher beispielsweise ebenfalls als ein Kunststoffbauteil ausgestaltet ist. Auch der zweite Halter 2.4 weist in axialer Richtung ein erstes, zweites und drittes hervorspringendes Element 2.41, 2.42, 2.43 auf, wobei diese im vorgestellten Ausführungsbeispiel als umlaufende Stege ausgestaltet sind. Diese hervorspringende Elemente 2.41, 2.42, 2.43 sind einstückig am zweiten Halter 2.4 angeformt. Außerdem umfasst auch der zweite Halter 1.4 eine Kavität 2.45 beziehungsweise einen nach einer Seite hin offenen Hohlraum.The
Weiterhin umfasst die zweite Bauteilgruppe 2 einen ersten, zweiten und dritten Schleifring 2.1, 2.2, 2.3. Die Schleifringe 2.1, 2.2, 2.3 weisen unterschiedliche Durchmesser D2.1, D2.2, D2.3 auf und sind mit radialem Abstand konzentrisch zueinander angeordnet. Im vorgestellten Ausführungsbeispiel sind die Schleifringe 2.1, 2.2, 2.3 als mehrschichtige Blechstreifen, insbesondere aus einem versilberten Messingmaterial, ausgebildet. Die als Blechstreifen ausgebildeten Schleifringe 2.1, 2.2, 2.3 haben vor ihrer Fertigstellung zunächst eine ebene Geometrie und weisen jeweils mehrere Laschen 2.11 (
Die Schleifringe 2.1, 2.2, 2.3 werden zu konzentrischen Ringen um die Achse A gebogen. Bezüglich der hervorspringenden Elemente 2.41, 2.42, 2.43 beziehungsweise der konzentrischen Stege werden die Schleifringe 2.1, 2.2, 2.3 im Zuge der weiteren Montage der zweiten Bauteilgruppe 2 jeweils radial außen liegend angeordnet, wobei die Laschen 2.11 durch in Umfangsrichtung versetzt angeordnete, axial durchgehende Schlitze 2.44 des zweiten Halters 2.4 hindurch gesteckt werden. Danach werden insbesondere die hindurch gesteckten Bereiche der Laschen 2.11 plastisch verformt, insbesondere in radialer Richtung umgebogen. Auf diese Weise ist der jeweilige Schleifring 2.1, 2.2, 2.3 am zweiten Halter 2.4 formschlüssig befestigt, so dass eine axiale und radiale Fixierung bezüglich des ersten Halters 1.4 erreicht ist. Die axial hervorspringenden Elemente 2.41, 2.42, 2.43 beziehungsweise Stege dienen zur Abstützung in radialer Richtung eines jeweiligen Schleifrings 2.1, 2.2, 2.3.The slip rings 2.1, 2.2, 2.3 are bent into concentric rings about the axis A. With regard to the protruding elements 2.41, 2.42, 2.43 or the concentric webs, the slip rings 2.1, 2.2, 2.3 are arranged in the course of the further assembly of the second group of
Die so hergestellten Bauteilgruppen 1, 2 werden nun zusammengefügt. Entsprechend wird die erste Bauteilgruppe 1, wie sie in der
Zur elektrischen Anbindung der Bürstenelemente 1.1, 1.2, 1.3 und der Schleifringe 2.1, 2.2, 2.3 wird pro Bürstenelement 1.1, 1.2, 1.3 beziehungsweise pro Schleifring 2.1, 2.2, 2.3 zumindest eine der Laschen nicht umgebogen. Diese im vorgestellten Ausführungsbeispiel nicht umgebogenen Laschen werden im Folgenden als Anschlusslaschen 2.12 bezeichnet, wobei in der
Im montierten Zustand sind also elektrische Ströme über die Kontaktzungen 1.13, 1.23, 1.33 zwischen der ersten und der zweiten Bauteilgruppe 1, 2 übertragbar sind. Die Biegelinien B der Kontaktzungen 1.13, 1.23, 1.33 verlaufen mit einer axialen Richtungskomponente, im vorgestellten Ausführungsbeispiel parallel zur Achse A. Die Ausbiegung der Kontaktzungen 1.13, 1.23, 1.33 liegt in radialer Richtung vor. Die Kontaktzungen 1.13, 1.23, 1.33 weisen in Umfangsrichtung eine Länge L auf und in axialer Richtung entlang der Biegeline B einen Breite w. Für die Funktionsfähigkeit der Schleifringeinheit ist es vorteilhaft, wenn das Verhältnis L/w von Länge L zur Breite w vergleichsweise groß ist. Im vorgestellten Ausführungsbeispiel nimmt dieses Verhältnis etwa den Wert 5,5 an.In the mounted state, therefore, electrical currents can be transmitted via the contact tongues 1.13, 1.23, 1.33 between the first and the
Im Betrieb der Schleifringeinheit dreht sich die zweite Bauteilgruppe 2 relativ zur ersten Bauteilgruppe 1. Infolgedessen entsteht ein schleifender Kontakt zwischen den Bürstenelementen 1.1, 1.2, 1.3 und den damit korrespondierenden Schleifringen 2.1, 2.2, 2.3. Insbesondere sind jeweils schleifende Kontakte zwischen dem ersten Bürstenelement 1.1 und dem ersten Schleifring 2.1, zwischen dem zweiten Bürstenelement 1.2 und dem zweiten Schleifring 2.2, sowie zwischen dem dritten Bürstenelement 1.3 und dem dritten Schleifring 2.2 hergestellt. Die Bürstenelemente 1.1, 1.2, 1.3 und die Schleifringe 2.1, 2.2, 2.3 sind über 360° weitgehend geschlossenen umlaufend ausgestaltet. Selbst wenn im Bereich eines Stoßes eines Schleifrings 2.1, 2.2, 2.3 der Kontakt zu einer der Kontaktzungen 1.13, 1.23, 1.33 unterbrochen oder reduziert wäre, würde dennoch eine ungestörte Übertragung der Ströme über die anderen Kontaktzungen 1.13, 1.23, 1.33 desselben Bürstenelements 1.1, 1.2, 1.3 auf den Schleifring 2.1, 2.2, 2.3 erfolgen. Durch die Schleifringeinheit ist eine Übertragung von elektrischen Strömen mit unbegrenztem Drehwinkel, also über beliebig viele Umdrehungen hinweg, erreichbar.During operation of the slip ring unit, the
Die konzentrischen Schleifringe 2.1, 2.2, 2.3 und die konzentrischen Bürstenelemente 1.1, 1.2, 1.3 sind in einer geometrischen Ebene angeordnet, welche orthogonal zur Achse orientiert ist. Insbesondere berühren sich jeweils die konzentrischen Schleifringe 2.1, 2.2, 2.3 und die dazu korrespondierenden konzentrischen Bürstenelemente 1.1, 1.2, 1.3 jeweils entlang einer Schleifbahn. Im vorgestellten Ausführungsbeispiel liegen drei Paare von Bürstenelementen 1.1, 1.2, 1.3 und Schleifringen 2.1, 2.2, 2.3 vor, so dass dementsprechend drei Schleifbahnen existieren. Die kreisförmigen Schleifbahnen sind in ein und derselben geometrischen Ebene angeordnet, welche orthogonal zur Achse orientiert ist, so dass also die Achse A diese geometrische Ebene orthogonal schneidet.The concentric slip rings 2.1, 2.2, 2.3 and the concentric brush elements 1.1, 1.2, 1.3 are arranged in a geometric plane which is oriented orthogonal to the axis. In particular, the concentric slip rings 2.1, 2.2, 2.3 and the corresponding concentric brush elements 1.1, 1.2, 1.3 each touch each other along a grinding path. In the illustrated embodiment, there are three pairs of brush elements 1.1, 1.2, 1.3 and slip rings 2.1, 2.2, 2.3, so that accordingly there are three sliding tracks. The circular sliding tracks are arranged in one and the same geometric plane, which orthogonal to the axis, so that the axis A intersects this geometric plane orthogonally.
Der erste Halter 1.4 und der zweite Halter 2.4 können an relativ zueinander drehbaren Maschinenteilen oder Tragarmen befestigt werden, deren relative Anordnung den Abstand a definiert. Derartige Maschinenteile können naturgemäß im Betrieb wechselnde Drehrichtungen annehmen und vibrieren oder Stöße in die Schleifringeinheit einleiten. Durch die Vibrationen oder Stöße kann der axiale Abstand a, wenn auch nur in geringem Maße, zeitlichen Änderungen unterliegen. Durch die vorliegende Konstruktion wird die Übertragung von Strömen durch derartige Betriebszustände nicht beeinträchtigt.The first holder 1.4 and the second holder 2.4 can be attached to relatively rotatable machine parts or support arms whose relative arrangement defines the distance a. Such machine parts can naturally assume changing directions of rotation in operation and vibrate or initiate shocks in the slip ring unit. As a result of the vibrations or impacts, the axial distance a may be subject to changes in time, albeit only to a limited extent. The present design does not affect the transmission of currents through such operating conditions.
