Description

Es sind walzenförmige Schleifkörper mit einer gewindeartig verlaufenden Schleiffläche bekannt, die bei paarweiser Anordnung mit ihrer Schleiffläche ineinandergreifen. Die Schleifflächen beider Schleifkörper bilden somit eine ununterbrochene Schleifrinne von keilförmigem Querschnitt, durch welche die Klinge bewegt und hierbei in einem Arbeitsgang an beiden Schneidenflächen abgezogen wird.They are roller-shaped grinding wheels with a thread-like one Known grinding surface which, when arranged in pairs, interlock with their grinding surface. The grinding surfaces of both grinding tools thus form an uninterrupted grinding groove of wedge-shaped cross-section through which the blade moves and here in one Operation is deducted from both cutting surfaces.

Bei den bekannten Schleifkörpern vorliegender Art kommt die gewindeartig verlaufende Schleiffläche zwischen den. Gängen einer auf den Kern des Schleifkörpers aufgesetzten Schraubenfeder zu stehen und wird bei. deren Zusammendrücken zwischen den Gängen der Feder eingespannt. Da jedoch beim Zusammendrücken der Schraubenfeder diese sich erweitert, kommt die Schleiffläche von dem Schleifkörper abzustehen, wodurch eine sichere Befestigung der Schleiffläche auf dem Schleifkörper nicht gewährleistet ist. Auch kann der Fall eintreten, daß sich bei starker Beanspruchung der Schleiffläche diese in die Nut der Ringe des Schleifkörpers eindrückt.In the case of the known grinding tools of the present type, the thread-like approach running grinding surface between the. Gears one on the core of the grinding wheel attached coil spring to stand and is at. their compression between clamped in the gears of the spring. However, as when compressing the coil spring if this expands, the grinding surface protrudes from the grinding wheel, as a result, a secure attachment of the grinding surface to the grinding wheel is not guaranteed is. It can also happen that the grinding surface is subject to heavy use this presses into the groove of the rings of the grinding tool.

Die Erfindung bezieht sich auf einen Schleifkörper mit gewindeartig verlaufender Schleiffläche und besteht darin, daß die zusammenschraubbaren Ringe des Schleifkörpers eine gewindeartig verlaufende Nut bilden, in die die aus einem Lederstreifen bestehende Schleiffläche hochkant zu stehen kommt und beim Zusammenschrauben der Ringe zwischen diesen fest eingeklemmt wird.The invention relates to a grinding body with a thread running grinding surface and consists in the fact that the rings that can be screwed together of the grinding wheel form a thread-like groove into which the one Leather strip of the existing sanding surface comes to stand on edge and when screwing together the rings are firmly clamped between them.

In der Zeichnung ist der Schleifkörper in einer beispielsweisen Ausführung dargestellt und zeigt ihn Abb. i und 2 in Ansicht und Draufsicht; Abb.3 zeigt eine Scheibe des Schleifkörpers in Draufsicht und Abb. 4 ein Stück der Abziehfläche in Seitenansicht.In the drawing, the grinding wheel is in an exemplary embodiment and shows it Fig. i and 2 in view and plan view; Fig.3 shows a Disc of the grinding wheel in plan view and Fig. 4 a piece of the honing surface in Side view.

Mit i sind die den Schleifkörper bildenden Ringe bezeichnet, die mittels Schrauben 2 zu einem festen Körper vereinigt sind, der mittels, Bohrung 5 auf eine Antriebsachse aufgesetzt wird. An der Stirnfläche bilden die Ringe i gemeinschaftlich eine gewindeartig verlaufende Nut 3, in welcher die aus einem Lederstreifen o. dgl. bestehende Schleiffläche hochkant zu stehen kommt. Beim Zusammenpressen der Ringe i mittels der Schrauben 2 werden die Lederstreifen zwischen den einzelnen Ringen i festgeklemmt. Die Dicke der Streifen ist so zu wählen, daß die Lederstreifen beim Zusammenschrauben der Ringe eine Pressung erfahren..With i the rings forming the grinding body are referred to, which by means of Screws 2 are combined into a solid body, which by means of, hole 5 on a Drive axle is placed. The rings i form jointly on the end face a thread-like groove 3, in which the leather strip o. existing sanding surface is upright. When pressing the rings together i by means of the screws 2 are the leather strips between the individual rings i stuck. The thickness of the strips is to be chosen so that the leather strips at When the rings are screwed together, a compression is experienced.

Der die Abziehfläche 4 bildende Lederstreifen kann aus - mehreren gleich dicken Stücken bestehen und an der unteren Kante zackenartig ausgeschnitten sein, damit sie sich besser der gewindeartig verlaufenden Nut 3 des Schleifkörpers anpassen.The leather strip forming the peel area 4 can consist of several consist of pieces of equal thickness and cut out like jagged edges on the lower edge be so that they better the thread-like groove 3 of the grinding wheel adjust.
