Description

Verfahren zur Vermeidung von Kohlestaubbrücken zwischen den Kohlelamellen bei der Herstellung von Kohlekollektoren für elektrische Maschinen oder Apparate Als Material für die Lamellen der Kollektoaren elektrischer Maschinen oder elektrischer Apparate wird neuerdings auch Kohle verwendet. Bei der Herstellung solcher Kohlckollekto@ren werden die Kohlelamellen, zunächst zu rechteckigen Platten gepreßt, oder sie werden aus größeren Kohleplatten herausgesohnitten. Sodann werden sie auf das notwendige Schrägmaß geschliffen, und mit isolierenden. Zwischenlagen zu einem Lamellenring -zusammengefügt. Die Stirnflächen dieses Lamcllenringes werden schließlich abgedreht, so, daß schwalbenschwanzförrnige oder andere schräge Flächen: entstehen, auf welche unter Zwischen. schalturig von isolierenden Schichten Halte- oder Preßringe aus Metall oder aus isolierenden Werkstoffen aufgesetzt werden.Procedure to avoid carbon dust bridges between the carbon louvers in the manufacture of coal collectors for electrical machines or apparatus As a material for the lamellae of the collectors of electrical machines or electrical machines Apparatus, coal has also been used recently. In the manufacture of such cabbage collectors are the coal lamellas, first pressed into rectangular plates, or they are Grown out of larger carbon plates. Then they focus on what is necessary Sanded at an angle, and with insulating. Interlayers to form a lamellar ring - put together. The end faces of this lamellar ring are finally turned off, so that dovetail-shaped or other inclined surfaces: arise on which under between. schalturig of insulating layers holding or pressing rings Metal or made of insulating materials.

Bei diesen. Arbeitsvorgängen bedarf es sehr großer Sorgfalt, um die Bildung von Kohles.taubbTücken zu verhindern. ErfindungsgeinM wird bei der Herstellung vom. Kohlekollektoren dien Bildung von. Kohlestaubbrücken und damit die Notwendigkeit, eine umverhältnismäßig große Sorgfalt anwenden zu müssen, dadurch vermieden, daß die zu rechteckigen; Platten gepreßten oder aus Kohle platten herausgeschnittenen, dann auf das notwendige Schrägmaß geschliffenen, Kohlelamellen vor ihrem Zusammenbau mit den Isälierzwischenlagen zu dem Lamellenring von jedem Oberflächenstaubbefreit werden "und einen staubdichten Überzug. oder eine staubdichte Imprägnierung erhalten. Die Entfernung des. Oberflächenstaubes kann z. B. durch Preßlu.ft oder durch: Auswaschen unter Druck oder durch Auswassahen und Bürsten, geschehen.With these. Work processes require a great deal of care in order to Prevent the formation of carbon deposits. Invention is used in the manufacture from the. Coal collectors are used to form. Coal dust bridges and thus the need having to apply a comparatively great care, thereby avoiding that those to be rectangular; Plates pressed or cut out of coal plates, then carbon lamellas, ground to the necessary diagonal dimension, before they are assembled with the insulating interlayers to the lamellar ring, free of any surface dust will "and received a dust-proof coating. or a dust-proof impregnation. The Removal of the surface dust can, for. B. by Preßlu.ft or by: washing out under pressure or by scrubbing and brushing.

So@ vorbehandelte Kohlelamellen geben beim Zusammenbeu zu einem Lamellenring keinen mehr abi. Hat man die Kofilelamellen nur mit einem staubdichten. Überzug versehen, so, tritt bei der Stirnflächenbeacbeitung des Lamellenringes durch Schleifen oder Drehen wieder Kohlestaut auf. Dieser läßt sich aber mit einem genügendkräftigen Wasserstrahl teilweise binden: und entfernen, ohne däß schädliche Neben- oder Nachwirkungen eintreten. Nach einer Imprägnierung, die genügend tief in die Kohle eingedrungen ist, entstehen bei der Bearbeitung nur Krümel und spanähnliche Abfälle, die zu Kohlestannbbrücken keinen-Ansaß geben.So @ pretreated carbon lamellas form a lamellar ring when assembled no more abi. If you have the Kofilelamellen only with a dustproof. coating provided, so, occurs in the end face machining of the lamellar ring by grinding or turn back coal jams. But this can be done with a strong enough Partially bind water jet: and remove without harmful side effects or after-effects enter. After an impregnation that penetrated deep enough into the coal is, only crumbs and chip-like waste arise during processing, which form carbon fiber bridges not give up.

Das Verfahren gemäß der Erfindung kann selbstverständlich auch bei der Herstellung von. Kontaktbahnen elektrischer Regeleinrichtungen ver-,vendet werden. ,The method according to the invention can of course also be used in the manufacture of. Contact tracks of electrical control devices are used. ,
