Abstract
Die Erfindung betrifft ein Schleifaggregat mit einer in einer Schleifspindel angeordneten Exzenterwelle zur Lagerung eines ein Schleifmittel tragenden Schleiftellers. Am oder in der Schleifspindel ist die ausgewuchtete Exzenterwelle drehstarr und längsverschiebbar gelagert. Auf dem freien Ende der Exzenterwelle ist der - in mindestens einer Rotationsrichtung gegenüber der Schleifspindel frei bewegliche - Schleifteller direkt oder mittels eines Schleiftellergehäuses über mindestens ein Wälz-, Gleit- oder Luftlager gelagert.The invention relates to a grinding unit with an eccentric shaft arranged in a grinding spindle for supporting a sanding disc bearing an abrasive. On or in the grinding spindle, the balanced eccentric shaft is torsionally rigid and mounted longitudinally displaceable. On the free end of the eccentric shaft of the - in at least one direction of rotation relative to the grinding spindle freely movable - sanding pad is mounted directly or by means of a sanding disk housing over at least one rolling, sliding or air bearings.
Mit der vorliegenden Erfindung wird ein Schleifaggregat entwickelt, das bei einem geringen Bauraum einen einfachen und robusten Aufbau hat. With the present invention, a grinding unit is developed, which has a simple and robust construction with a small space.
