Description
Kreiselmähwerk Die Erfindung bezieht sich-aufein Kreiselmähwerk nach der deutschen Patentanmeldung-P 16 57 o20.0 mit kreis- bzw. kreisringförmigen, aus einem Trägermaterial mit darin eingebetteten Schneidelementen bestehenden Schneidkörpern.Rotary mower The invention relates to a rotary mower the German patent application P 16 57 o20.0 with circular or circular ring-shaped a carrier material with cutting elements embedded therein.
Nach dieser Patentanmeldung ist vorgeschlagen, die Schneidkörper von Kreiselmähwerken als quer zur Schnittebene elastische Scheiben metallischen - und/oder oxydkeramischen Charakters.According to this patent application it is proposed that the cutting body of Rotary mowers as metallic and / or elastic discs transversely to the cutting plane oxide-ceramic character.
auszubilden, um dadurch zu erreichen, daß letztere den Steinen oder ähnlichen Bodenhindernissen in gewissem Sinne ausweichen bzw. unbeschädigt darüber hinweggleiten können.train in order to achieve that the latter the stones or Dodge similar ground obstacles in a certain sense or go undamaged over them can slide away.
Versuche haben gezeigt, daß besonders gute Schneideigenschaften dieser Schneidkörper gegeben sind, wenn die Schneidelemente faserförmig ausgebildet und über ein Trägermaterial annähernd radial in die Schneidkörper elngebettet sind. Nach einem wesentlichen Merkmal der Erfindung weist hierbei das Trägermaterial eine geringere Verschleiß- bzw. Abrie.bSestigkelt auf als der Faserwerkstoff. Diese Maßnahme hat zur Folge, daß das Trägermaterial beim Arbeiten der Maschine, bedingt durch den schnelleren Verschleiß an der Schnittkante der Schneidkörper, zwischen den Spitzen der Schneidfasern etwa halbkreisförmig ausgerieben wird und da urch eine am Umfang gezahnte Schneidscheibe mit ä.uf3erst guten und über einen langen Zeitraum gleichbleibenden Schneideigenschaften entsteht. Die Spitzen der Schneidfasern werden hierbei von dem kegelförmig. um diese verbleibenden Trägermaterial gestützt, wodurch sie weitgehend gegen Abbrechen geschützt sind.Tests have shown that particularly good cutting properties of this Cutting bodies are given when the cutting elements are fiber-shaped and are embedded approximately radially in the cutting bodies via a carrier material. According to an essential feature of the invention, the carrier material here has a less wear and tear than the fiber material. This measure has the consequence that the carrier material when working the machine, due to the faster wear on the cutting edge of the cutting body, between the tips of the cutting fibers is rubbed out in an approximately semicircular shape and thereby one on the circumference Serrated cutting disc with extremely good and consistent over a long period of time Cutting properties arise. The tips of the cutting fibers are thereby of the conical. supported around these remaining support material, thereby largely reducing them are protected against breaking.
Die Schneidelemente können aus Stahldrähten, Glas-, Kunststoff-, Kohlenstoffasern oder ähnlichen faserförmigen und verschleißfesten Stoffen bestehen und einzeln oder zu Bündeln zusammengefaßt in die Schneidkörper eingebettet sein.The cutting elements can be made of steel wires, glass, plastic, carbon fibers or similar fibrous and wear-resistant materials and individually or be embedded in the cutting body combined into bundles.
Der Vorteil dieser erfindungsgemäßen Ausführung liegt nun neben einer beträchtlichen Verbesserung der Schlagfestigkeit und damit der Standdauer der Schneidkörper besonders darin, daß ein evtl. Zuschmiereii der für gutes Schneiden notwendigen Freiräume zwischen den Schneidelementen, wie dies bei oxydkeramischen Schneidscheiben in .ußerst ungünstigen Arbeitsverhältnissen eintreten kann, vermieden wird.The advantage of this embodiment according to the invention is now next to one considerable improvement in the impact resistance and thus the service life of the cutting body especially in the fact that a possible clogging of the necessary for good cutting Clearances between the cutting elements, as is the case with oxide ceramic cutting disks can occur in extremely unfavorable employment relationships, is avoided.
In der Zeichnung sind Ausführungsbeispiele der Erfindung dargestellt. Es zeigen Fig. 1 eine Seitenansicht des unteren Teiles eines h'reiselmähwerl:es im Schnitt, Fig. 2 eine teilweise geschnittene Draufsicht auf eine beispielsweise Ausführung einer Mähscheibe und Fig. 7 einen Schnitt entlang der Linie A - A in Fig. 2 Die f'aserförmig ausgebildeten, beispielsweise aus Glasfasern bestehenden Schneidelemente 1 sind annähernd radial in die über Schrauben 2 oder dergleichen mit den Kreiseln 5 des in Fig. 1 dargestellten Kreiselmähwerkes 4 verbundenen, quer zur Schnittebene elastischen Schneidkö.rper 5, 5' huber ein Trägerm-terial 6 eingebettet, welches beispielsweise, wie in Fig. 2 und 3 gezeigt, als Kreisringkörper auf einer @ünnen Metallscheibe lo aufgekleb@ ist und deren Außendurc@messer ring1'örmit überragt. Dieses die Schneidfasern 1 umgebende Tr.igermaterial 6 weist hierbei eine geringere Verschleiß- bj. Ab-@iebsfestigkeit auf als der Faserwerkstoff 1, was zur Folge liat, daß das Trc.gerlnaterial 6 beim Arbeiten der Maschine, bedingt durch den schnelleren Verschleiß an der Schnittkante 7 der Schneidkörper 5, 5', zwischen den Spitzen 8 der Schneidfasern 1 etwa halbkreisförmig 9 ausgerieben wird und dadurch eine am Umfang 7 gezahnte Schneidscheibe entsteht.Exemplary embodiments of the invention are shown in the drawing. 1 shows a side view of the lower part of a rotary mower in section, Fig. 2 is a partially sectioned plan view of an example Execution of a mower disc and FIG. 7 shows a section along the line A - A in Fig. 2 The fiber-shaped, for example made of glass fibers Cutting elements 1 are approximately radially in the via screws 2 or the like connected to the rotors 5 of the rotary mower 4 shown in Fig. 1, transversely to the cutting plane elastic cutting body 5, 5 'embedded in a carrier material 6, which, for example, as shown in Fig. 2 and 3, as a circular ring body on a @ is glued on to the inner metal disk and whose outer diameter protrudes beyond ring1'örmit. This carrier material 6 surrounding the cutting fibers 1 has a lower thickness Wear bj. Abrasion resistance than fiber material 1, which results in that the Trc.gerlnaterial 6 when working the machine, due to the faster Wear on the cutting edge 7 the cutting body 5, 5 ', between the tips 8 of the cutting fibers 1 is rubbed out approximately in a semicircle 9 and thereby a cutting disk toothed on the circumference 7 is created.
