Abstract
Beschrieben wird ein mit Druckluft betriebenes Schleifgerät mit einem Rotor (40), der Schlitze (41) aufweist, in denen Rotorschieber (42) radial verschiebbar sind, wobei der Rotor (40) mit den Rotorschiebern (42) in einer gegenüber der Drehachse (A) des Rotors (40) exzentrisch angeordneten Hülse (30) drehbar ist. Die Hülse (30) ist in einem Stator (25) mittels eines Luftspalts (70) luftgelagert. Durch die Reibung der Rotorschieber (42) an der Hülse (30) wird die Hülse in Drehrichtung mitgenommen. Hülse (30) und Rotorschieber (42) sind aus einem Material, das als wesentliche Bestandteile Phenolharz und Baumwollgewebe enthält.A grinding machine operated with compressed air is described with a rotor (40) which has slots (41) in which rotor slides (42) can be moved radially, the rotor (40) with the rotor slides (42) in a direction opposite the axis of rotation (A ) of the rotor (40) eccentrically arranged sleeve (30) is rotatable. The sleeve (30) is air-borne in a stator (25) by means of an air gap (70). Due to the friction of the rotor slide (42) on the sleeve (30), the sleeve is carried in the direction of rotation. Sleeve (30) and rotor slide (42) are made of a material that contains phenolic resin and cotton fabric as essential components.
Description
Die Erfindung betrifft ein Schleifgerät der im Oberbegriff des Patentanspruches 1 genannten Art.The Invention relates to a grinder in the preamble of the claim 1 mentioned Art.
Derartige
Schleifgeräte
sind bei feinen Schleifarbeiten, die von Hand geführt werden,
im Einsatz und arbeiten mit hohen Drehzahlen (siehe
Aufgabe der Erfindung ist es, ein Schleifgerät dieser Art derart weiterzubilden, dass weniger Reibungsverluste entstehen. Somit sollen höhere Drehzahlen erreichbar und der Verschleiß geringer sein.task the invention is to develop a grinding device of this type in such a way that there is less friction loss. Thus, higher speeds should be achievable and less wear his.
Die Lösung dieser Aufgabe erfolgt durch ein Schleifgerät mit den im Patentanspruch 1 angegebenen Merkmalen. Die Erfindung betrifft ferner die in den Unteransprüchen angegebenen vorteilhaften Weiterbildungen.The solution this task is performed by a grinder with in the claim 1 specified characteristics. The invention further relates to the dependent claims specified advantageous developments.
