Abstract

The rotary tool is in the form of a rubber or soft plastic washer (1) with an outer crown and an inner crown. The outer crown forms a toothed crown with elastic teeth, and the inner one is for connecting to a rotating holder. There are stabilizing webs (6) offset width and height between the machining teeth (4) in the circumferential direction of the outer crown, forming a joint with the machining teeth.

Description

Die Erfindung betrifft ein Rotationswerkzeug in der Ausführungsform einer Ringscheibe aus Gummi oder gummiartigem Kunststoff zur Oberflächenbearbeitung, mit einem Außenkranz und einem Innenkranz, wobei der Außenkranz einen Zahnkranz mit biegeelastischen Bearbeitungszähnen bildet und der Innenkranz zum Anschluss an einen rotativ antreibbaren Scheibenhalter eingerichtet ist.The invention relates to a rotary tool in the embodiment of an annular disc made of rubber or rubbery plastic for surface treatment, with an outer rim and an inner rim, wherein the outer rim forms a ring gear with bending elastic machining teeth and the inner ring is adapted for connection to a rotatably driven disc holder.

Es ist ein derartiges Rotationswerkzeug bekannt, bei dem die Bearbeitungszähne verhältnismäßig lang sind und daher beachtliche Hebelarme bilden. Zwar hat sich dieses Rotationswerkzeug an sich bewährt, jedoch kann eine ungeschickte Handhabung bei extrem hohen Drehzahlen zu frühzeitigem Verschleiß der Bearbeitungszähne und selbst zu einem Bruch der Bearbeitungszähne führen (vgl. DE 198 45 166 B4). - Hier will die Erfindung Abhilfe schaffen.It is such a rotary tool is known in which the machining teeth are relatively long and therefore form considerable lever arms. Although this rotary tool has proven itself, but an awkward handling at extremely high speeds to premature wear of the machining teeth and even lead to a fraction of the machining teeth (see DE 198 45 166 B4). - Here the invention wants to remedy the situation.

Der Erfindung liegt das technische Problem zugrunde, ein Rotationswerkzeug der eingangs beschriebenen Ausführungsform zu schaffen, bei dem sich die Bearbeitungszähne durch reduzierten Verschleiß und reduzierter Bruchgefahr selbst dann auszeichnen, wenn mit extrem hohen Drehzahlen und unvorschriftsmäßiger Handhabung gearbeitet wird.The invention is based on the technical problem to provide a rotary tool of the embodiment described above, in which the machining teeth are characterized by reduced wear and reduced risk of breakage even when working with extremely high speeds and improper handling.

Diese Aufgabe löst die Erfindung bei einem gattungsgemäßen Rotationswerkzeug dadurch, dass in den Zahnlücken zwischen den Bearbeitungszähnen in Umfangsrichtung des Außenkranzes verlaufende Stabilisierungsstege von vorgegebener Breite und Höhe angeordnet sind und mit den Bearbeitungszähnen einen Verbund bilden. - Diese Maßnahmen der Erfindung haben zur Folge, dass die Länge der von den Bearbeitungszähnen gebildeten Hebelarme durch die Stabilisierungsstege hinreichend reduziert wird, so dass ein Bruch der Bearbeitungszähne überraschenderweise auch dann verhindert wird, wenn die Breite der Stabilisierungsstege geringer als die Breite der Bearbeitungszähne ist. Hinzu kommt, dass auf diese Weise auch der Verschleiß deutlich reduziert wird und selbst unter Berücksichtigung eines zunehmenden Verschleißes die Rundlaufgenauigkeit des Außenkranzes und folglich des Zahnkranzes mit den Bearbeitungszähnen optimiert wird. Das gilt selbst für den Fall einer ungeschickten bzw. unvorschriftsmäßigen Handhabung bei hohen Drehzahlen. Daraus resultieren erhöhte Lebensdauer und Radier- sowie Reinigungsleistung ohne Verletzungs- bzw. Beschädigungsgefahr in Bezug auf die zu bearbeitenden Oberflächen.This object is achieved by the invention in a generic rotary tool characterized in that in the tooth gaps between the machining teeth in the circumferential direction of the outer ring extending stabilizing webs of predetermined width and height are arranged and form a composite with the working teeth. - These measures of the invention have the consequence that the length of the lever arms formed by the machining teeth is sufficiently reduced by the stabilizing webs, so that a fraction of the machining teeth is surprisingly prevented even if the width of the stabilizing webs is less than the width of the machining teeth is. In addition, in this way, the wear is significantly reduced and even with consideration of increasing wear, the concentricity of the outer ring and thus the ring gear is optimized with the machining teeth. This is true even in the case of awkward or improper handling at high speeds. This results in increased life and erasing and cleaning performance without injury or damage to the surfaces to be machined.

Weitere erfindungswesentliche Merkmale sind im Folgenden aufgeführt. So sieht die Erfindung vor, dass die Stabilisierungsstege aus dem gleichen Werkstoff wie die Bearbeitungszähne bestehen und an den Flanken der Bearbeitungszähne angeformt sind. Dadurch bilden die Stabilisierungsstege mit den Bearbeitungszähnen und folglich dem Außenkranz vorzugsweise eine Baueinheit mit gegenseitiger Abstützung der Bearbeitungszähne. Weiter lehrt die Erfindung, dass die Stabilisierungsstege in Umfangsrichtung des Außenkranzes fluchten und mittig zwischen den Bearbeitungszähnen angeordnet sind. Diese symmetrische Ausbildung des Außenkranzes unterstützt die Rundlaufgenauigkeit beim Arbeitseinsatz des erfindungsgemäßen Rotationswerkzeuges. Zweckmäßigerweise weisen die Stabilisierungsstege eine radiale Höhe auf, die etwa 2/3 der Zahnhöhe der Bearbeitungszähne entspricht. Weiter entspricht die axiale Breite der Stabilisierungsstege etwa 1/5 bis 2/5 der axialen Breite der Bearbeitungszähne. Unter Berücksichtigung solcher Abmessungen werden besonders optimale Effekte in Bezug auf Verschleißreduzierung und Reduzierung der Bruchgefahr erreicht. Das gilt auch unter Berücksichtigung der Tatsache, dass die Kopfdicke der Bearbeitungszähne in Umfangsrichtung des Zahnkranzes etwa 7 bis 9 mm, vorzugsweise 8 mm beträgt.Further inventive features are listed below. Thus, the invention provides that the stabilizing webs consist of the same material as the machining teeth and are integrally formed on the flanks of the machining teeth. As a result, the stabilizing webs with the machining teeth and consequently the outer rim preferably form a structural unit with mutual support of the machining teeth. Next, the invention teaches that the stabilizing webs are aligned in the circumferential direction of the outer ring and are arranged centrally between the machining teeth. This symmetrical design of the outer ring supports the concentricity during the labor input of the rotary tool according to the invention. Conveniently, the stabilizing webs have a radial height which corresponds to about 2/3 of the tooth height of the machining teeth. Further, the axial width of the stabilizing webs corresponds to about 1/5 to 2/5 of the axial width of the machining teeth. Taking into account such dimensions, particularly optimal effects in terms of reducing wear and reducing the risk of breakage are achieved. This is also true in consideration of the fact that the head thickness of the machining teeth in the circumferential direction of the ring gear is about 7 to 9 mm, preferably 8 mm.
