Description

Bei- den 'bekannten Tandembürstenhalte-rn -mit zwei oder mehr in der Umfangsrichtung -hintereinander angeordnetem Bürsten für Schleifringe elek= trischer Maschinen und Apparate ist der Befesti-. gungsteil des Halters in der Umfangsrichtung des Schleifringes neben den Bürsten am Halter befestigt. Der Platzbedarf dieser Halter in der Umfangsrichtung - ist daher sehr groß. Wird hierbei zur Platzersparnis der Befestigungsteil nur auf -einer Seite des Halters angebracht, so besteht vor allem bei hohen Umfangsgeschwindigkeiten mit Rücksicht auf die große Länge des Halters die Gefahr, daß er in Schwingungen gerät und damit der Stromüber-. gang schlecht ausfällt.Both of the known tandem brush holders with two or more in the Circumferential direction - brushes arranged one behind the other for electrical slip rings Machines and apparatus is the fastening. supply part of the holder in the circumferential direction of the slip ring attached to the holder next to the brushes. The space required for this Holder in the circumferential direction - is therefore very large. This is used to save space the fastening part is only attached to one side of the holder, so there is especially at high circumferential speeds, taking into account the long length of the holder the danger that it will start to vibrate and thus the current over-. gear bad fails.

Diese Nachteile werden gemäß der Erfindung dadurch vermieden, daß der Befestigungsteil des Halters in axialer Richtung neben den-Bürsten.- am Halter befestigt wird. Neben: den Bürstentaschen befinden sich nunmehr in- der- Umfangsrichtung keine Halterteile; so daß verhältnismäßig viele Halter bzw. solche mit mehreren Bürsten. am Umfang des Schleifringes angeordnet-werden können. Außerdem wird gemäß der Erfindung selbst bei Haltern mit großer Länge in der Umfangsrichtung eine gute Abstützung auf ihre ganze Länge erreicht, so daß Vibrationen praktisch wegfallen. Werden als-Andrückvorrichtungen Druckhebel verwendet, so werden diese zweckmäßigerweise ebenfalls in axialer Richtung neben den Bürsten, beispielsweise auf der den Befestigungsteilen gegenüberliegenden Seite, gelagert. Diese Hebel können. dann alle untereinander gleichgemacht werden, was. die Herstellung vereinfacht. Bei Verwendung von radial gerichteten Andrückfedernkönnen --erfindungsgemäß deren Widerlager besonders einfach gestaltet Werden.These disadvantages are avoided according to the invention in that the fastening part of the holder in the axial direction next to the brushes.- on the holder is attached. Next to: the brush pockets are now in the circumferential direction no holder parts; so that a relatively large number of holders or those with several To brush. can be arranged on the circumference of the slip ring. In addition, according to of the invention is a good one even with holders having a great length in the circumferential direction Support achieved over its entire length, so that vibrations are practically eliminated. If pressure levers are used as pressure devices, these are expediently also in the axial direction next to the brushes, for example on the fastening parts opposite side, stored. These levers can. then all among each other be equalized what. simplifies manufacture. When using radial Directional pressure springs can - according to the invention, their abutment particularly easily be designed.

In der Zeichnung ist ein. Ausführungsbeispiel der Erfindung- angedeutet. Der Halter i besitzt eine Bürstentasche 2, die drei in der Umfangsrichtung des Schleifringes 3 hintereinander angeordnete Bürst°n q. bis 6 aufnehmen kann. Gemäß der Erfindung ist der Befestigungsteil 7 des Halters in der Richtung der .Schleifringachse neben den Bürsten am Halter befestigt. Auf der gleichen: Seite können auch die Widerlager für die hier radial gerichteten Andrückfedern mit dem Halterkörper verbunden sein. Mit Rücksicht auf die gute Befestigung des Halters auf seiner ganzen Länge eignet sich dieser besonders für hohe Umfangsgeschwindigkeiten.In the drawing is a. Embodiment of the invention indicated. The holder i has a brush pocket 2, the three in the circumferential direction of the slip ring 3 brushes arranged one behind the other ° n q. up to 6 can accommodate. According to the invention is the fastening part 7 of the holder in the direction of .Sleifringachse next the brushes attached to the holder. The abutments can also be on the same side be connected to the holder body for the pressure springs directed radially here. With regard to the good fastening of the holder along its entire length, it is suitable This is particularly suitable for high peripheral speeds.

Eine Bürstenhalteranordnung gemäß der Erfindung wird zweckmäßigerweise dadurch geschaffen, daß ein gewöhnlicher Bürstenhalter mit zwei oder mehr in axialer Richtung nebeneinander angeordneten Bürsten um 9o°' gedreht am Umfang des Schleifringes befestigt wird. Das hat den Vorteil, däß vorhandene Halter- der erstgenannten Art ohne jede Änderung als Tandemhalter Verwendung finden können. Es muß nur die Befestigung des Halters entsprechend geändert werden.A brush holder assembly according to the invention becomes useful created by having an ordinary brush holder with two or more in axial Direction of brushes arranged next to one another rotated by 90 ° on the circumference of the slip ring is attached. This has the advantage that existing holders of the first-mentioned type can be used as a tandem holder without any changes. It just needs the attachment of the holder can be changed accordingly.
