Description
Kohle ist gegen Zug- und Biegebeanspruchungen wenig widerstandsfähig. Die bekannten, aus Kohle aufgebauten Schleifringe elektrischer Maschinen und Apparate eignen sich daher nicht für hohe Umfangsgeschwindigkeiten. Dieser Nachteil wird gemäß der Erfindung dadurch vermieden, daß der Kontaktring des Schleifringes am Umfang zur Aufnahme der Fliehkräfte mit einem oder mehr Halteringen umgeben ist, deren Festigkeit größer als die des Kontaktringes ist. Auf diese Wise gelingt es, selbst bei hohen Umfangsgeschwindigkeiten. den Kontaktring vor großer Ausweitung zu bewahren, so daß er keine große Dehnungen, erfährt und daher nicht zerstört wird.Coal is not very resistant to tensile and bending loads. The well-known slip rings of electrical machines and apparatus made of carbon are therefore not suitable for high peripheral speeds. This disadvantage will avoided according to the invention that the contact ring of the slip ring on The circumference is surrounded by one or more retaining rings to absorb the centrifugal forces, whose strength is greater than that of the contact ring. In this way it succeeds even at high peripheral speeds. the contact ring before great expansion to be preserved so that it does not experience any great stretching and is therefore not destroyed.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Gemäß der Erfindung ist der aus Kohle bestehende Kontaktring i des Schleifringes am Umfang mit einer Bandage 2 umgeben., die auf den Kontaktring i aufgewickelt wird. An Stelle der Bandage kann auch ein aus Metall; z. B. Stahl, bestehender Haltering verwendet werden. Erstreckt sich der Haltering über einen. großen Teil der axialen Länge des Kontaktringes, dann: schleifen die Bürsten, wie dargestellt; an einer oder an beiden Stirnflächen des Kontaktringes. Ist hingegen am Umfang neben den Halteringen ausreichend Platz vorhanden, dann können gegebenenfalls zusätzlich Bürsten auch am Umfang des Kontaktringes schleifen. Der elektrische Anschluß! 4 wird an der Innenseite des Kontaktringes angeordnet. Hierbei ist zwischen dem beispielsweise im Bereich des Kontaktringes als Zylinder ausgebildeten Anschluß- 4 und der Welle 5 bzw. Nabe des Schleifringes Isolation 6 vorgesehen. Nunmehr ist es möglich, den Kontaktring geteilt auszuführen. Die Teilung kann dabei nach Radialebenen oder quer axialen Ebenen erfolgen. Der Kontaktring kann jedoch auch in anderer Weise geteilt werden, da die einzelnen Teile durch den Haltering fest zusammengehalten werden. Beispielsweise kann der Kontaktring auch aus mehreren konzentrisch liegenden Ringen aufgebaut sein.An exemplary embodiment of the invention is shown in the drawing. According to the invention, the contact ring i made of carbon is the slip ring Surrounded on the circumference with a bandage 2, which is wound onto the contact ring i. Instead of the bandage, one made of metal can also be used; z. B. steel, existing retaining ring be used. Does the retaining ring extend over one. large part of the axial Length of contact ring, then: grind the brushes as shown; at a or on both end faces of the contact ring. On the other hand, it is next to the There is sufficient space for the retaining rings, so that additional brushes can be used if necessary also grind around the circumference of the contact ring. The electrical connection! 4 is on arranged on the inside of the contact ring. Here is between, for example in the area of the contact ring formed as a cylinder connection 4 and the shaft 5 or hub of the slip ring insulation 6 is provided. It is now possible to use the Execute contact ring divided. The division can be according to radial planes or across axial planes. However, the contact ring can also be divided in other ways because the individual parts are firmly held together by the retaining ring. For example, the contact ring can also consist of several concentric rings be constructed.
Die Erfindung kann mit Vorteil bei all den Schleifringen verwendet werden, die einen Kontaktring aus gegen Zug- und Biegebeanspruchungen wenig widerstandsfähigem Werkstoff besitzen. Beispielsweise kann der Kontaktring auch aus Perlitgußeisen bestehen.The invention can be used to advantage with all of the slip rings that a contact ring made of little resistant to tensile and bending stresses Own material. For example, the contact ring can also be made of perlite cast iron exist.
