Abstract

A slip ring arrangement for an electrical connection between two parts that can be rotated with respect to one another has at least one slideway having V-shaped grooves. At least two brushes which extend in the V-shaped grooves are provided. The brushes are connected electrically together and fixed in a holder such that the brushes are fastened in different planes, that is to say at different distances from the rotation axis of the slideway. As a result, increased insensitivity to vibrations and mechanical impacts is achieved.

Description

Schwingungsunempfindlicher Bürstenblock für Schleifringe  Vibration-insensitive brush block for slip rings
Technisches Gebiet Die Erfindung betrifft einen Bürstenblock sowie eine Schleif ringanordnung zur Übertragung elektrischer Signale mittels Schleifkontakten zwischen gegeneinander drehbaren Teilen. Auf einer Schleifbahn aus elektrisch leitfähigem Material schleift wenigstens ein Schleifkontakt, auch Bürste genannt, aus einem ebenfalls elektrisch leitfähigen Material. Durch den galvanischen Kontakt zwischen Schleif- bahnen und Kontakt kann elektrischer Strom übertragen werden. TECHNICAL FIELD The invention relates to a brush block and a grinding ring arrangement for transmitting electrical signals by means of sliding contacts between mutually rotatable parts. On a sliding track made of electrically conductive material, at least one sliding contact, also called a brush, grinds from a likewise electrically conductive material. Due to the galvanic contact between the tracks and contact electrical current can be transmitted.
Stand der Technik State of the art
In der DE 10 2008 001 361 AI ist eine Schleifringanordnung offenbart, bei der eine Bürste mit wenigstens zwei Schleifdrähten in einer Schleifbahn mit einer V- Nut läuft. Die Schleifdrähte haben unterschiedliche Durchmesser und berühren die Schleifbahn an unterschiedlichen Winkelpositionen. Dadurch ergibt sich eine erhöhte Toleranz gegenüber mechanischen Schwingungen und Stößen sowie ein reduzierter Kontaktwiderstand. In DE 10 2008 001 361 AI a slip ring assembly is disclosed in which a brush with at least two grinding wires in a sliding track with a V-groove runs. The grinding wires have different diameters and touch the grinding path at different angular positions. This results in an increased tolerance to mechanical vibrations and shocks as well as a reduced contact resistance.
Die EP 0662736 A offenbart eine Schleifringanordnung, bei der eine einzelne Bürste mehrere Drähte aufweist, die in einer V-Nut laufen. Dadurch ergibt sich durch die Parallelschaltung mehrerer Kontakte ein niedriger Übergangswiderstand. In der US 4398113 A ist eine weitere Schleifringanordnung mit Bürsten offenbart, die eine Vielzahl feinster Drähte aufweisen. Auch hier ergibt sich aufgrund der mehrfachen Kontakte ein relativ niedriger Übergangswiderstand. EP 0 662736 A discloses a slip ring assembly in which a single brush has a plurality of wires running in a V-groove. This results in the parallel connection of several contacts a low contact resistance. In US 4398113 A a further slip ring assembly with brushes is disclosed having a plurality of very fine wires. Again, due to the multiple contacts results in a relatively low contact resistance.
Nachteilig an dem Stand der Technik ist, dass keine dieser Schleifringanordnun- gen bei hohen Schock-und Stoßbelastungen einen zuverlässigen elektrischen Kontakt ermöglicht. So treten bei externen kurzfristigen starken Stößen oder Vibrationen kurzzeitige Kontaktunterbrechungen durch Abheben der Bürsten von der Schleifbahn auf. Ebenso können auch Unterbrechungen durch reibinduzierte interne Schwingungen auftreten, die bei verschiedenen Rotationsge- schwindigkeiten entstehen. A disadvantage of the prior art is that none of these slip ring arrangements permits reliable electrical contact under high shock and impact loads. Thus, in the case of external short-term strong shocks or vibrations, short-term contact interruptions occur due to lifting of the brushes from the grinding path. Likewise, interruptions may occur due to friction-induced internal vibrations, which occur at different rotational speeds.
Darstellung der Erfindung Presentation of the invention
Der Erfindung liegt die Aufgabe zugrunde, einen Bürstenblock sowie eine Schleifringanordnung derart auszugestalten, dass diese auch bei starken kurzfristigen Stößen oder Vibrationen einen zuverlässigen elektrischen Kontakt gewährleistet. Gleichzeitig soll diese Schleifringanordnung einfach und kostengünstig herstellbar sein, sowie eine hohe Lebensdauer und Zuverlässigkeit besitzen. The invention has for its object to design a brush block and a slip ring assembly such that it ensures a reliable electrical contact even with strong short-term shock or vibration. At the same time this slip ring assembly should be simple and inexpensive to produce, and have a long life and reliability.
Diese Aufgabe wird durch eine Vorrichtung nach Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben. Ein erfindungsgemäßer Bürstenblock für eine Schleifbahn umfasst wenigstens eine erste Bürste (auch Drahtbürste genannt) sowie eine zweite Bürste aus elektrisch leitfähigem Material, die in einer Halterung fixiert und elektrisch miteinander verbunden sind. Die beiden Bürsten sind in der Halterung in unterschiedlichen Ebenen und somit in unterschiedlichen Abständen zur Drehachse einer Schleifbahn fixiert. Damit ergeben sich unterschiedliche Längen der Bürsten zwischen der Halterung und dem Auflagepunkt an der Schleifbahn. Damit sind die mechanischen Eigenschaften der beiden Bürsten unterschiedlich. Es resultiert hieraus eine erhöhte Unempfindlichkeit gegenüber Stößen und Vibrationen. This object is achieved by a device according to claim 1. Advantageous embodiments of the invention are specified in the subclaims. An inventive brush block for a sliding track comprises at least a first brush (also called wire brush) and a second brush made of electrically conductive material, which are fixed in a holder and electrically connected to each other. The two brushes are fixed in the holder in different planes and thus at different distances from the axis of rotation of a grinding path. This results in different lengths of the brush between the holder and the contact point on the grinding path. This is the mechanical properties of the two brushes differ. This results in an increased insensitivity to shocks and vibrations.
Bevorzugt umfasst die Halterung eine erste Trägerplatte sowie eine zweite in einem Abstand daran befestigte zweite Trägerplatte. Die erste Bürste ist zumin- dest an der zweiten Trägerplatte mechanisch befestigt. Zudem kann sie auch an der ersten Trägerplatte mechanisch befestigt und/oder kontaktiert sein. Die zweite Bürste ist ausschließlich an der ersten Trägerplatte mechanisch befestigt und wird auch mit dieser kontaktiert. The holder preferably comprises a first carrier plate and a second second carrier plate fastened thereto at a distance therefrom. The first brush is at least mechanically fastened to the second carrier plate. In addition, it can also be mechanically fastened and / or contacted on the first carrier plate. The second brush is mechanically attached exclusively to the first support plate and is also contacted with this.
Bevorzugt ist es, wenn zumindest die erste Trägerplatte als Leiterplatte ausge- führt ist. So lässt sich hiermit auf einfache Weise eine Kontaktierung der Bürsten erreichen. Durch eine mechanische Verbindung von erster Trägerplatte und zweiter Trägerplatte wird die gesamte Steifigkeit des Bürstenblocks verbessert. Bevorzugt wird die mechanische Verbindung von erster Trägerplatte und zweiter Trägerplatte dämpfend ausgeführt, so dass eine Entkopplung zwischen den bei- den Leiterplatten besteht. It is preferred if at least the first carrier plate is designed as a printed circuit board. This makes it easy to contact the brushes. By a mechanical connection of the first carrier plate and the second carrier plate, the entire rigidity of the brush block is improved. Preferably, the mechanical connection of the first carrier plate and the second carrier plate is carried out damping, so that there is a decoupling between the two printed circuit boards.
Bevorzugterweise umfasst die zweite Leiterplatte noch ein Fenster, durch welches die zweite Bürste von der ersten Leiterplatte aus hindurchtreten kann, ohne die zweite Leiterplatte zu berühren. Preferably, the second circuit board still comprises a window through which the second brush can pass from the first circuit board without touching the second circuit board.
In einer weiteren vorteilhaften Ausführungsform ist die Halterung einstückig, beispielsweise ein Kunststoff-Spritzgussteil. In a further advantageous embodiment, the holder is in one piece, for example a plastic injection molded part.
Die Bürsten sind bevorzugt Metalldrähte und umfassen wenigstens ein elektrisch leitfähiges Material. Bevorzugt haben Sie einen Kern aus einem mechanisch stabilen und federelastischen Material, wie beispielsweise Stahl oder Messing sowie eine äußere Beschichtung oder Hülle aus einem elektrisch gut leitenden und vorzugsweise korrosionsbeständigen Material, wie beispielsweise Gold oder einer Goldlegierung. Besonders günstig ist es, wenn auf den Bürstenblöcken Drahtbürsten mit unterschiedlichen Drahtgeometrien, insbesondere unterschiedlichen Drahtdurchmessern vorhanden sind. The brushes are preferably metal wires and comprise at least one electrically conductive material. Preferably, you have a core of a mechanically stable and resilient material, such as steel or brass, and an outer coating or shell of a highly electrically conductive and preferably corrosion-resistant material, such as gold or a gold alloy. It is particularly favorable if wire brushes with different wire geometries, in particular different wire diameters, are present on the brush blocks.
Eine erfindungsgemäße Schleif ringanordnung weist eine Schleifbahn sowie we- nigstens einen der hier offenbarten Bürstenblöcke auf. Zur Führung der Bürsten hat die Schleifbahn bevorzugt wenigstens eine V-Nut. Grundsätzlich sind aber auch Schleifbahnen mit anderen Geometrien einsetzbar. Dies können beispielsweise ebene Schleifbahnen oder Schleifbahnen mit U-förmigen Nuten (halbkreisförmig, elliptisch) sein. Bevorzugterweise umfasst die Schleif ringanordnung mehrere der erfindungsgemäßen Bürstenblöcke, wobei bevorzugterweise alle auf derselben Bahn laufenden Bürsten elektrisch parallel geschaltet sind. A slip ring assembly according to the invention has a slideway and at least one of the brush blocks disclosed herein. For guiding the brushes, the grinding path preferably has at least one V-groove. In principle, however, also sliding tracks with other geometries can be used. These may be, for example, flat sliding tracks or sliding tracks with U-shaped grooves (semicircular, elliptical). Preferably, the abrasive ring assembly comprises a plurality of brush blocks according to the invention, wherein preferably all running on the same path brushes are electrically connected in parallel.
Besonders vorteilhaft ist es, wenn wenigstens zwei Bürstenblöcke bezogen auf die Drehachse gegenüberliegend angeordnet sind. Vorteilhaft ist es, wenn zumindest ein Bürstenblock schwingungsgedämpft gelagert ist. Bevorzugt sind die Bürstenblöcke unterschiedlich schwingungsgedämpft gelagert. So haben Sie bevorzugt unterschiedliche Dämpfungswerte und/oder unterschiedliche Resonanzfrequenzen. It is particularly advantageous if at least two brush blocks are arranged opposite one another with respect to the axis of rotation. It is advantageous if at least one brush block is mounted vibration-damped. Preferably, the brush blocks are mounted differently vibration damped. So you have preferred different attenuation values and / or different resonance frequencies.
Vorteilhafterweise haben wenigstens zwei Bürstenblöcke unterschiedliche For- men. Dadurch sind auch die Schwingungseigenschaften dieser Bürstenblöcke unterschiedlich. Advantageously, at least two brush blocks have different shapes. As a result, the vibration characteristics of these brush blocks are different.
Vorteilhafterweise werden mehrere, elektrisch miteinander verbundene Bürstenblöcke in gleichen Abständen um die Schleifbahn verteilt angeordnet. So können beispielsweise 3 Bürstenblöcke jeweils um 120 Grad versetzt oder auch 4 Bürstenblöcke jeweils um 90 Grad versetzt angeordnet werden. Dadurch kann die Stoß- und Vibrationsfestigkeit weiter erhöht werden. Alternativ werden mehrere, elektrisch miteinander verbundene Bürstenblöcke in unterschiedlichen Abständen um die Schleifbahn verteilt angeordnet. So können beispielsweise 3 Bürstenblöcke um 90, 120 und 150 Grad versetzt angeordnet werden. Auch dadurch kann die Stoß- und Vibrationsfestigkeit weiter erhöht werden. Advantageously, a plurality of electrically interconnected brush blocks are arranged distributed at equal intervals around the grinding path. For example, 3 brush blocks can be offset by 120 degrees, or 4 brush blocks can be offset by 90 degrees. As a result, the shock and vibration resistance can be further increased. Alternatively, a plurality of electrically interconnected brush blocks are arranged distributed at different distances around the grinding path. For example, 3 brush blocks can be offset by 90, 120 and 150 degrees. This also allows the shock and vibration resistance can be further increased.
In einer weiteren vorteilhaften Ausgestaltung hat wenigstens eine Drahtbürste wenigstens eine teilweise Ummantelung um die Schwingungseigenschaften zu verändern. Diese Ummantelung kann beispielsweise aus einem elastischen Material sein. Sie ist bevorzugt außerhalb des Bereichs, der mit der Schleifbahn in Kontakt steht angeordnet. Besonders bevorzugt haben verschiedene Drahtbürsten auf unterschiedlichen Bürstenblöcken unterschiedliche Arten der Ummantelung. Besonders günstig ist es, wenn beispielsweise ein erster Schleifdraht auf einem ersten Bürstenblock eine Ummantelung aufweist, während ein zweiter Schleifdraht auf einem zweiten Bürstenblock keine Ummantelung aufweist. In a further advantageous embodiment, at least one wire brush has at least one partial sheathing to change the vibration properties. This sheath may be made of an elastic material, for example. It is preferably located outside of the area in contact with the slideway. More preferably, different wire brushes on different brush blocks have different types of sheath. It is particularly favorable if, for example, a first grinding wire has a casing on a first brush block, while a second grinding wire does not have a casing on a second brush block.
In einer anderen Ausgestaltung stehen die Enden der Schleifdrähte wesentlich über den Kontaktpunkt mit der Schleifbahn hinaus. Die überstehende Länge liegt in einem Bereich zwischen 0,2-2 mal der Länge zwischen dem Bürstenblock und dem Kontaktpunkt mit der Schleifbahn. Besonders bevorzugt wird das überstehende Ende vom Schleifring weg gebogen. In another embodiment, the ends of the sanding wires are substantially beyond the point of contact with the sanding path. The protruding length is in a range between 0.2-2 times the length between the brush block and the contact point with the grinding path. Particularly preferably, the protruding end is bent away from the slip ring.
Beschreibung der Zeichnungen Description of the drawings
Die Erfindung wird nachstehend ohne Beschränkung des allgemeinen Erfindungsgedankens anhand von Ausführungsbeispielen unter Bezugnahme auf die Zeichnungen exemplarisch beschrieben. The invention will now be described by way of example without limitation of the general inventive idea by means of embodiments with reference to the drawings.
Figur 1 zeigt einen Erfindungsgemäßen Bürstenblock sowie eine Schleifbahn Figur 2 zeigt schematisch die Geometrie einer erfindungsgemäßen Vorrichtung FIG. 1 shows a brush block according to the invention and a sliding track Figure 2 shows schematically the geometry of a device according to the invention
In Figur 1 ist ein erfindungsgemäßer Bürstenblock dargestellt. Der Bürstenblock hat eine Halterung, welche aus der ersten Leiterplatte 20 sowie der zweiten Lei- terplatte 21 besteht. Die beiden Leiterplatten sind über Verbindungsschraube in 23 (hier mit zusätzlicher Distanzrolle oder als Distanzbolzen ausgeführt) derart miteinander verbunden, dass sie in unterschiedlichen Ebenen bzw. in unterschiedlichen Abständen zur Drehachse der Schleifbahn 10 liegen. An der Halterung sind eine erste Bürste 30 sowie eine zweite Bürste 31 befestigt. Die erste Bürste 30 ist über Lötstellen 25 mit der ersten Leiterplatte 20 zur elektrischen Kontaktierung verbunden. Sie ist zusätzlich mechanisch mit der zweiten Leiterplatte 21, bevorzugt über eine weitere Lötstelle 25 verbunden. Die mechanische Verbindung kann aber auch jede andere Art einer mechanischen Verbindung sein. Wesentlich ist hier die mechanische Fixierung an der zweiten Leiterplatte. Die zweite Bürste 31 ist ebenfalls über eine Lötstelle 25 mit der ersten Leiterplatte 20 elektrisch und mechanisch verbunden. Somit ist der Abstand der mechanischen Fixierung der beiden Bürsten zum Mittelpunkt der Schleifbahn unterschiedlich. Die erste Bürste 30 liegt am Auflagepunkt 11 an der Schleifbahn 10 auf, während die zweite Bürste 31 am Auflagepunkt 12 auf der Schleifbahn 10 aufliegt. Damit die zweite Bürste 31 nicht in mechanischen Kontakt mit der zweiten Leiterplatte 21 treten kann weist diese ein Fenster 22 zum Durchtritt der zweiten Bürste 31 auf. FIG. 1 shows a brush block according to the invention. The brush block has a holder which consists of the first printed circuit board 20 and the second printed circuit board 21. The two printed circuit boards are connected to one another in this way by means of connecting screws in FIG. 23 (in this case with an additional spacer roller or as spacer bolts), so that they lie in different planes or at different distances from the axis of rotation of the grinding track 10. On the holder, a first brush 30 and a second brush 31 are attached. The first brush 30 is connected via solder joints 25 to the first circuit board 20 for electrical contacting. It is additionally mechanically connected to the second printed circuit board 21, preferably via a further solder joint 25. The mechanical connection can also be any other type of mechanical connection. Essential here is the mechanical fixation on the second circuit board. The second brush 31 is also connected via a solder joint 25 with the first circuit board 20 electrically and mechanically. Thus, the distance between the mechanical fixation of the two brushes to the center of the grinding path is different. The first brush 30 rests against the contact point 11 on the grinding path 10, while the second brush 31 rests on the contact point 12 on the grinding path 10. So that the second brush 31 can not come into mechanical contact with the second circuit board 21, this has a window 22 for the passage of the second brush 31.
In Figur 2 ist schematisch die Geometrie der e rf i nd u ngsge mä ße n Vorrichtung dargestellt. Wegen der besseren Übersichtlichkeit sind hier die Unterkanten der Leiterplatten 20 und 21 sowie die Außenkante der Schleifbahn 10 nur schematisch als Linie dargestellt. Die Mittelachse 14 geht von der Drehachse der Schleifbahn 15 senkrecht auf den Bürstenblock, hier dargestellt als senkrecht nach oben verlaufend. Die Bürste 31 hat gegenüber der Unterkante der ersten Leiterplatte 20 einen Winkel 41 sowie eine Länge 42. Sie liegt am Kontaktpunkt 12 unter einem Winkel 45 zur Mittelachse an der Schleifbahn 10 an. Der Winkel liegt bevorzugterweise in einem Bereich von 20° bis 60°. Die notwendige Länge einer Bürste ergibt sich aus dem Abstand zwischen dem Befestigungspunkt der Bürste an der Leiterplatte und dem Kontaktpunkt der Bürste mit der Schleifbahn zuzüglich einem Überstand, mit dem die Bürste über den Kontaktpunkt hinaus ragt. Die Bürste 30 hat gegenüber der Unterkante der zweiten Leiterplatte 21 einen Winkel 40 sowie eine Länge 43. Der Winkel 40 ist kleiner als der Winkel 41. Bevorzugterweise liegt der in einem Bereich von 80 % bis 95 % des Winkels 41. Entsprechend ist auch die Länge 43 der ersten Bürste kürzer als die Länge 42 der zweiten Bürste. Die erste Bürste liegt hier am Kontaktpunkt 11 unter einem Winkel 46 zur Mittelachse an der Schleifbahn 10 an. Es wird hierbei ein konstanter Überstand angenommen. FIG. 2 schematically shows the geometry of the device of the invention. Because of the better clarity here the lower edges of the printed circuit boards 20 and 21 and the outer edge of the grinding path 10 are shown only schematically as a line. The central axis 14 extends from the axis of rotation of the grinding path 15 perpendicular to the brush block, shown here as vertically upwards Gradient. The brush 31 has an angle 41 and a length 42 relative to the lower edge of the first printed circuit board 20. It is located at the contact point 12 at an angle 45 to the central axis of the grinding path 10 at. The angle is preferably in a range of 20 ° to 60 °. The necessary length of a brush results from the distance between the attachment point of the brush to the circuit board and the point of contact of the brush with the grinding path plus a projection with which the brush protrudes beyond the point of contact. The brush 30 has an angle 40 and a length 43 relative to the lower edge of the second printed circuit board 21. The angle 40 is smaller than the angle 41. Preferably, this is in a range of 80% to 95% of the angle 41. The length is also corresponding 43 of the first brush shorter than the length 42 of the second brush. The first brush is here at the contact point 11 at an angle 46 to the central axis of the grinding path 10 at. It is assumed here a constant supernatant.
Gestrichelt ist noch der Verlauf einer Bürste 32 bei einer Anordnung entsprechend dem Stand der Technik eingezeichnet. Hierbei wäre die erste Bürste entsprechend der zweiten Bürste an der ersten Leiterplatte befestigt entsprechend würde hierbei die Bürste an einem Kontaktpunkt 13 unter einem Winkel 45 zur Mittelachse an der Schleifbahn anliegen. Dieser Winkel wäre ebenso groß wie der Winkel 44 und größer als der Winkel 46. Dashed still the course of a brush 32 is shown in an arrangement according to the prior art. Here, the first brush according to the second brush would be attached to the first circuit board according to the brush would abut at a contact point 13 at an angle 45 to the central axis of the grinding path. This angle would be as large as the angle 44 and greater than the angle 46.
