<p>The invention relates to a fastening apparatus for abrasive wheels, comprising an abrasive-wheel carrier with wide-headed fastening pins which are pressed against the abrasive-wheel carrier by elastic force and can project out of the coupling surface of the abrasive-wheel carrier by actuation with a suitable tool, the fastening pins having the task of fixing a plate connected to the abrasive wheel and thus of ensuring the fastening of the abrasive wheel on the abrasive-wheel carrier. The invention is distinguished in that the plate has, on the coupling side, projections in the form of arcuate beads which are located in one plane parallel to the aforementioned coupling surface, are all oriented in the same rotary direction, are at a uniform distance from one another and from the centre point and are located in a central region of the same. The number of projections corresponds to the number of fastening pins, the pin heads of which can be firmly clamped beneath the arcuate beads which engage about a considerable part of the circumference of the pin heads, the plate and the abrasive-wheel carrier being provided with centrally arranged coupling parts for driving the abrasive wheel in co-rotation.</p> |
