Description

Bei schleifenden Kontakten, wie beispielsweise hei Kohlebürsten von Motoren, ergeben sich oft infolge nicht rechtzeitiger Auswechselung der Kohle Schwierigkeiten. Durch unzulässig weiteAbnutzung dir Kohle schleifen metallische Teile, z. B. die Druckfedern der Kohlen, unmittelbar als Kontaktübertrager auf dein Kollektor. Hierdurch tritt ein starkes Feuern auf, und dit (>lrerflä ehe des Kollektors wird beschädigt.With sliding contacts, such as carbon brushes from Engines, problems often arise as a result of not replacing the coal in good time. Metallic parts, e.g. B. the Coal compression springs, directly as contact transmitters on your collector. Through this If a strong fire occurs and the surface of the collector is damaged.

Die vorliegende Erfindung vermeidet diese Nachteile durchdieVerwendung eirne#sfedernd gelagerteli Gliedes, welches das Kontaktstück abtastet und 1>ei Erreichung der kleinsten nutzbaren Länge des Kontaktstückes, die elektrische Verbindung unterbricht. Vorteilhaft ist die Anordnung des Abtastorgans so getrottcn, daß dieses bei Erreichen der hleinstelt nutzbarenLänge des Kontaktstückes bzw. der Kohlebürste über eine Kante des Kontaktstückes abgleitet und hierdurch denStrom'kreis unterbricht. Dadurch wird stets eine rechtzeitige Anzeige erfolgen, daß die Kolik bürste ihre kleinste nutzliat-e läng: (erreicht hat, so daß ein Auswechseln der Bürste vorgelionimen «-erden muß. Beschädigungen des Kollektors bzw. des Motors können somit nicht treten.The present invention avoids these disadvantages by using it a spring-loaded link which scans the contact piece and 1> when it is reached the smallest usable length of the contact piece that interrupts the electrical connection. The arrangement of the scanning element is advantageous in such a way that it is when it is reached the smallest usable length of the contact piece or the carbon brush over a The edge of the contact piece slides off and thereby interrupts the current circuit. Through this There will always be a timely indication that the colic is brushing its smallest Nutzliat-e long: (has reached, so that a replacement of the brush vorgelionimen «- must earth. Damage to the collector or the motor can therefore not occur.

In den Fig. i und 2 ist die Erfindung schematisch an einem Ausführungsbeispiel dargestellt. Die auf (lern Kollektor gleitende Kohlebürste t wird von einem federnd ausgebildeten Abtastorgan 2 in bezug auf ihre nutzbare Länge abgetastet. Das federnde Abtastorgan 2 ist mit einem Bolzen 3 versehen, der an der Seitenfl;iche glcit@t. 1)i: Strornzuführutt@r zur Bürste t erfolgt iil>er den ortsfesten Kontakt 5. ITierbei ist die Anordnung sot getroffen, daß der Kontakt 3, solange die Bürste t eine ausreichende nutzbare Länge aufweist. geschlossen ist. Zu dein Zeitpunkt. zu dem die Bürste 1 die kleinste ahnutz- liare Länge erreicht hat. gleitet tler Holzen von der Seitenfläche 4 der Dürste alt und üttrnet dabei Jett Kontakt 5. wodurch der Stroiniki-eis unterbrochen wird. Das federnde Abtastorgan ist bei 6 fest ein- gespannt und wird entgegen schier Federwirkun- durch den Bolzen 3, solange dieser 110c11 auf der Seitenfläche d der Bürste gleitet, nach rechts ge- drückt, so daß der Kontakt ; itl diesem 7eitlitinl<; gesc1ilosseli geltalteti ist. In FIGS. I and 2, the invention is shown schematically using an exemplary embodiment. The carbon brush t sliding on the collector is scanned for its usable length by a resilient scanning element 2. The resilient scanning element 2 is provided with a bolt 3, the on the side panel glcit @ t. 1) i: Strornzuführutt @ r The fixed contact 5 is made to the brush t. The arrangement is made so that the Contact 3 as long as the brush t sufficient having usable length. closed is. To yours Time. to which the brush 1 has the smallest useful reached liare length. the wood slides off the Side surface 4 of the thirsts old and otttrnet Jett Contact 5. whereby the Stroiniki-eis interrupted will. The resilient sensing element is fixed at 6 tensioned and is counter to the sheer spring action through the bolt 3 as long as this 110c11 on the Side surface d of the brush slides, to the right presses so that the contact; itl this 7eitlitinl <; is closed.
