 hat aus diesem Grunde vielfach die Schleifspindel in nachgiebigen Lagern gelagert. Diese Bauart ist aber sehr kompliziert und gibt, da die treibende, starr gelagerte Welle und die angetriebene, elastisch gelagerte   Schleifspindel   hintereinander angeordnet   TA erden müssen,   eine grosse Baulänge des Schleifgerätes, die hauptsächlich bei   Handschleifgeräten   die Führung ungünstig beeinflusst. 



   Gemäss der Erfindung wird nun die Schleifscheibe selbst durch Vermittlung von Gummiringen oder ändern elastischen Mitteln nachgiebig mit der starr gelagerten Antriebswelle verbunden, und die für die Übertragung des Drehmomentes erforderlichen Reibungsflächen werden so angeordnet, dass sie die Bewegung der Schleifscheibe in der zur Antriebswelle senkrechten Richtung nicht hindern.

 for this reason has often stored the grinding spindle in flexible bearings. However, this design is very complicated and, since the driving, rigidly mounted shaft and the driven, elastically mounted grinding spindle have to be grounded one behind the other, TA, a large overall length of the grinding device, which mainly has an unfavorable influence on the guidance of hand-held grinding devices.



   According to the invention, the grinding wheel itself is flexibly connected to the rigidly mounted drive shaft by means of rubber rings or by changing elastic means, and the friction surfaces required for the transmission of the torque are arranged so that they do not prevent the grinding wheel from moving in the direction perpendicular to the drive shaft prevent.

Claims

In Fig. 1 of the drawing, the example embodiment of a grinding wheel attachment according to the invention is shown in the untensioned state. In the bore of the grinding wheel 1, correspondingly shaped sleeves 2 are arranged in order to relieve the pressure on the rubber, which acts radially outwards and which grasp the side surfaces of the wheel with flanges. The rubber rings 3 are supported on the one hand against the flanges of the sleeve 2 and on the other hand against the support plates 4 and 5. The support plates are pressed together by means of the screw nut 7 arranged on the grinding spindle 6 (Fig. 2), with at least a space between the support plates on the axis remains the same as the width of the billet, in order to allow yielding even in the tensioned state.

In order to prevent mutual rotation of the support plates when tightening the nut 7 or during operation, a wedge is provided which prevents the two support plates from rotating against one another. allows- PATENT CLAIM: Floating disc fastening, characterized in that the disc is connected to the shaft by an elastic means; which simultaneously applies the torque from the shaft to the disk EMI1.3 EMI1.4 ** WARNING ** End of CLMS field may overlap beginning of DESC **.
