Abstract
Lagereinrichtung für ein tragbares Arbeitsgerät, insbesondere Freischneide- oder Pflanzenbesprühgerät oder ähnliches, mit einer Tragplatte (1) zur federnden Lagerung eines Antriebsmotors, die eine angenähert dreieckige Form mit einem umlaufenden Rand (4) sowie eine in ihrem Mittenbereich angeordnete Nabe (3) aufweist, dadurch gekennzeichnet, daß die Tragplatte (1) als einstückiges Leichtgußteil ausgebildet und die Nabe (3) mit dem Rand (4) durch verbindende Rippen (5, 6) versteift ist, wobei die Rippen (5, 6) von der Nabe (3) zum umlaufenden Rand (4) hin radial verlaufen.Storage facility for a portable work equipment, in particular free-cutting or Pflanzenbesprühgerät or the like, with a support plate (1) for resilient mounting of a drive motor, which is an approximately triangular Shape with a peripheral edge (4) and one in its center area arranged hub (3), characterized in that the support plate (1) as one piece Leichtgußteil formed and the hub (3) with the edge (4) by connecting Ribs (5, 6) is stiffened, wherein the ribs (5, 6) from the hub (3) extend radially to the peripheral edge (4).
Description
Die Erfindung betrifft eine Lagereinrichtung für ein tragbares Arbeitsgerät, insbesondere nach dem Oberbegriff des Anspruchs 1.The The invention relates to a storage device for a portable working device, in particular according to the preamble of claim 1.
In
der
Die Tragplatte dient zur federnden Lagerung des Antriebsmotors und als Schwenkvorrichtung für denselben, um eine flexible Handhabung des Freischneiders zu gewährleisten. Sie ist als geschweißte Stahlblechkonstruktion von erheblichem Gewicht konzipiert, was insbesondere bei einem tragbaren Gerät von Nachteil ist.The Support plate is used for resilient mounting of the drive motor and as Pivoting device for the same, to ensure flexible handling of the brush cutter. It is as a welded sheet steel construction designed of considerable weight, which is particularly disadvantageous in a portable device is.
Der Erfindung liegt die Aufgabe zugrunde, eine Tragplatte für den Antriebsmotor eines handgeführten Freischneidegerätes zu schaffen, die geringes Gewicht aufweist und einfach herzustellen ist.Of the Invention is based on the object, a support plate for the drive motor a hand-held Brush cutter to create, which has low weight and easy to manufacture is.
Die Aufgabe wird gelöst durch die kennzeichnenden Merkmale des Anspruchs 1.The Task is solved by the characterizing features of claim 1.
Durch die einstückige Leichtgußausführung der Tragplatte entfallen Fügevorgänge und Schweißnähte. Dadurch verringern sich Bauaufwand und Dauerbruchgefahr. Die Rippen gewährleisten die notwendige Steifigkeit.By the one-piece Lightweight version of the Support plate eliminates joining operations and Welds. Thereby Reduce construction costs and fatigue hazard. Ensure the ribs the necessary rigidity.
Die Druckgußausführung in Magnesium oder auch Kunststoff verringert das Gewicht der Tragplatte.The Die casting execution in Magnesium or plastic reduces the weight of the support plate.
Dasselbe gilt für die beanspruchungsgerechte Gestaltung der Tragplatte, mit dem abgerundeten, umlaufenden Rand und den sich zu diesem hin verjüngenden Rippen. Die erfindungsgemäße Verbindung von den Rändern benachbarter Rippen durch abwechselnd äußere und innere Flächen ergibt eine geschlossene, gleichsam gewellte Tragplatte hoher Biegesteifigkeit.The same thing applies to the claim-oriented design of the support plate, with the rounded, circumferential Edge and the tapering ribs. The compound of the invention from the edges adjacent ribs by alternately outer and inner surfaces results a closed, almost corrugated support plate high bending stiffness.
Durch die bis zur Auflagefläche reichenden ersten Rippenpaare, die auf die Ecken der Tragplatte gerichtet sind, wird die Biegesteifigkeit der Tragplatte in der Hauptbeanspruchungsrichtung erhöht.By up to the contact surface reaching first pairs of ribs, which are directed to the corners of the support plate are, the flexural rigidity of the support plate in the main direction of stress elevated.
Die runden, als Einmündung gestalteten Öffnungen im Bereich der drei Ecken der Tragplatte dienen der Montage und der Führung von Federelementen zur federnden Lagerung des Antriebsmotors.The round, as a junction designed openings in the area of the three corners of the support plate are used for mounting and the leadership of spring elements for resilient mounting of the drive motor.
Die Verbindung zwischen Innenzylinder und Nabe über radiale Stege verhindert eine zu große Materialanhäufung im Nabenbereich und die damit verbundene Lunkerbildung.The Connection between inner cylinder and hub via radial webs prevented an excessive accumulation of material in the Hub area and the associated voids formation.
Weitere Merkmale ergeben sich aus den weiteren Ansprüchen, der nachfolgenden Beschreibung und der Zeichnung, in der ausgeführte Beispiele der Erfindung schematisch dargestellt sind.Further Features emerge from the further claims, the following description and the drawing in which executed Examples of the invention are shown schematically.
