Description

Für die Stromabnahme an Kommutatoren oder Schleifringen elektrischer Maschinen sind Anordnungen bekannt, bei denen die auf dem Kommutator schleifende Bürste in einem Kasten geführt ist und von einer· Feder an die Kommutator- oder Schleifringfläche angepreßt wird. Um Vibrationen der Bürste im Führungskasten zu vermeiden, sind noch entweder an der Bürste oder anFor drawing current on commutators or slip rings in electrical machines arrangements are known in which the brush sliding on the commutator is guided in a box and is supported by a Spring is pressed against the commutator or slip ring surface. To avoid vibrations of the Avoid brushes in the guide box are either still on or on the brush

ίο dem Kasten befestigte Federn vorgesehen, die die Bürste auch an die Kastenwand anpressen. Die Bürste wird dabei an die Kastenwand angepreßt, deren Fläche in Richtung der Breitseite parallel zur Achse der elektrisehen Maschine ist. Man hat diese Anordnung gewählt, weil man sich sagte, daß dadurch den durch den Kommutatorumlauf hervorgerufenen Bürstenschwingungen, die in einer Ebene normal zur Maschinenachse ver-ίο springs attached to the box are provided, which also press the brush against the box wall. The brush is against the box wall pressed, the surface of which is parallel to the axis of the electric view in the direction of the broad side Machine is. This arrangement was chosen because it was said to oneself that it would cause the commutator to circulate caused brush vibrations, which move in a plane normal to the machine axis

ao laufen, am besten entgegengewirkt wird.ao run, is best counteracted.

Die vorliegende Erfindung betrifft eine neue Stellung derartiger in einem Kasten geführter Bürsten an Kommutatoren oder Schleifringen elektrischer Maschinen, die den Vorzug hat, daß sie für beide Umlaufrichtungen des Läufers der Maschine gleich wirksam ist. Außerdem haben Versuche gezeigt, daß bei der neuen Anordnung gegenüber der oben geschilderten bekannten die Vibrationen der Bürste im Kasten wesentlich vermindert sind, so daß auch der Stromübergang zwischen Bürste und Kommutator wesentlich vollkommener ist. Erfindungsgemäß wird die Bürste von den. seitlichen Federn an die zur Maschinenachse normale Kastenführungsfläche angepreßt. Die ganze Bürstenanordnung ist also gegenüber der bisherigen um 90 ° gedreht.The present invention relates to a new position of such boxes guided Brushes on commutators or slip rings of electrical machines, which has the advantage that they are used for both directions of rotation of the machine's rotor is equally effective. In addition, tests have shown that compared to the new arrangement the above-described known the vibrations of the brush in the box significantly are reduced, so that the current transfer between brush and commutator is much more perfect. According to the invention is the brush of the. lateral springs pressed against the box guide surface normal to the machine axis. The whole The brush arrangement is rotated by 90 ° compared to the previous one.

Die Achse der Bürste, längs der diese im Führungskasten entlang gleitet, kann entweder auf der Kommutator- oder Schleifringfiäche normal stehen oder einen spitzen Winkel mit dieser Fläche einschließen. Namentlich die letztere Anordnung hat sich als vorteilhaft erwiesen.The axis of the brush along which it slides in the guide box can either stand normally on the commutator or slip ring surface or at an acute angle with include this area. The latter arrangement in particular has proven to be advantageous proven.

Die Zeichnung veranschaulicht die neue Anordnung, wobei 1 die Lamelle eines Kommutators, dessen Achse in der Zeichenebene liegt, bedeutet, 2 die Kohlebürste, 3 eine Feder, die die Kohle an die Fläche der Kastenführung 4 anpreßt, deren Fortsetzung von der Kommutatorachse geschnitten wird.The drawing illustrates the new arrangement, where 1 is the lamella of a commutator, whose axis lies in the plane of the drawing, means 2 the carbon brush, 3 a spring that attaches the carbon to the surface of the Box guide 4 presses, the continuation of which is cut by the commutator axis.
