Kohlebürstenhalterung für elektrische MaschinenCarbon brush holder for electrical machines
Die Neuerung betrifft eine Kohlebürstenhalterung für elektrische Maschinen, insbesondere für kleinere Motoren. Die Kohle sitzt in einem Bürstengehäuse und wird von einer Feder gegen den Kommutator gedrückt. Da zwischen Bürstengehäuse und Kohle ein bestimmtes Spiel vorhanden ist, besteht die Gefahr, daß die Kohle durch" das Drehen des Kommutators verkantet und Wackelschwingungen entstehen, die ein Bürstenfeuer sowie Bürstengeräusche hervorrufen.The innovation relates to a carbon brush holder for electrical machines, especially for smaller motors. The coal sits in a brush housing and is held by a spring against the commutator pressed. There is a certain play between the brush housing and the carbon is present, there is a risk that the coal by "turning of the commutator is tilted and wobbly vibrations arise, which cause a brush fire and brush noises.
Zur Vermeidung dieses Nachteiles schlägt die Neuerung vor, daß zwischen der Kohle und der Bürstenfeder eine gegen die Kohle anliegende und diese im Bürstengehäuse führende Scheibe vorgesehen ist, deren Außendurchmesser nur geringfügig kleiner als der Innendurchmesser des Bürstengehäuses ist. Durch den Federdrupk liegt dieTo avoid this disadvantage, the innovation suggests that between the carbon and the brush spring a disk resting against the carbon and guiding it in the brush housing is provided whose outer diameter is only slightly smaller than the inner diameter of the brush housing. Due to the spring pressure, the

Kohle mit ihrem Kopfende fest gegen die genannte Scheibe an. Da die Scheibe selbst aufgrund ihres Durchmessers und ihrer Stärke im Bürstengehäuse nicht verkanten kann, verhindert sie, daß die Kohlenflanken zur Anlage gegen das Gehäuseinnere kommen. Dadurch wiederum werden Wackelschwingungen der Bürste und damit ein übermäßiges Bürstenfeuer und Geräusche verhindert. Außerdem erhöht' sich die Kohlestandzeit und die Funkstörspannung wird herabgesetzt.Coal with its head end firmly against the said disc. Since the Disc itself due to its diameter and its strength in Brush housing cannot tilt, it prevents the carbon flanks come to rest against the interior of the housing. This in turn wobbling vibrations of the brush and thus excessive brush fire and noises are prevented. In addition, the Carbon service life and the radio interference voltage is reduced.
Die Zeichnung zeigt ein Ausführungsbeispiel der neuerungsgemäßen Kohlebürstenhalterung. Mit 1 ist ein Bürstengehäuse bezeichnet, in dem die Kohlebürste 2 sitzt, welche unter der Wirkung einer Feder 3 steht. Gemäß der, Neuerung ist zwischen der Feder und dem Kopfende' 4 der Kohle eine Scheibe 5 angeordnet. Zu diesem Zweck ist die an sich entsprechend der Kohleausbildung viereckige Innenausnehmung 6 des Gehäuses 1 mit einer zusätzlichen Bohrung 7 versehen. Die Scheibe 5 besitzt eine gewisse Stärke und ihr Außendurchmesser ist nur um so viel geringer als der Durchmesser der Bohrung 7, daß die Scheibe gerade noch in der Bohrung 7 gleiten kann.The drawing shows an embodiment of the carbon brush holder according to the innovation. 1 with a brush housing is referred to, in which the carbon brush 2 sits, which is under the action of a spring 3. According to the, innovation is between the pen and the Head end '4 of the coal a disk 5 is arranged. To this end is the square inner recess in accordance with the carbon formation 6 of the housing 1 is provided with an additional bore 7. The disk 5 has a certain thickness and its outer diameter is only so much smaller than the diameter of the bore 7 that the disk can just slide in the bore 7.
Die Kohlebürste 2 wird von.der Feder 3 gegen den Kommutator gedruckt, wodurch ihr Kopfende'4 fest gegen die Scheibe 5 anliegt. Die Scheibe 5 selbst kann innerhalb des Gehäuses 1. nicht verkanten und verhindert damit auch im wesentlichen ein Verkanten der Kohle 2. Diese kann sich nur ganz geringfügig seitlich bewegen, so daß die Kohlenflanken nicht gegen das Gehäuseinnere zum Anliegen kommen. Die Kohle steht somit -fest und es entstehen keine Wackelschwingungen, die ein Bürstenfeuer hervorrufen. - 'The carbon brush 2 is pressed by the spring 3 against the commutator, whereby its head end 4 rests firmly against the disk 5. The disc 5 itself cannot tilt inside the housing 1 and thus also essentially prevents the carbon 2 from tilting can only move very slightly sideways, so that the coal flanks do not come into contact with the inside of the housing. The coal is stable and there are no wobbles, which cause a brush fire. - '
