Patent number: 9138870Abstract: A tool has disks or ring disks arranged for metal-cutting, which are stacked on top of each other in an overlapping fashion and engage into each other at their incisions which reach from the outer circumference up to the center point of the disks or the inner circumference of the ring disks. The incisions of the directly adjacent disks or ring disks are respectively angularly offset by 360°/n, with n being the number of the disks or ring disks. A production method is also provided for such a tool, in which the disks or ring disks are incised up to the center point or inner circumference, are completely slid into each other at the incisions, folded towards one another and displaced until an angular offset of the incisions of 360°/n is produced.Type: GrantFiled: July 27, 2012Date of Patent: September 22, 2015Assignee: Gerd Eisenblaetter GmbHInventor: Gerd Eisenblaetter

Publication number: 20080152422Abstract: The present invention relates to a shaft-hub connection for fastening a grinding tool on a grinding tool driveshaft and the use of a shaft-hub connection for fastening a grinding tool on a grinding tool driveshaft. To simplify the mounting of a grinding tool on a grinding tool driveshaft, the peripheral surface of the shaft or the internal surface of the grinding tool hub has a number of circular wedge faces and the other of the two components has a number of counterparts working together with the circular wedge faces, by which a friction lock is producible by twisting the shaft and hub in relation to one another. Furthermore, a rotational lock is provided for blocking and releasing the relative twisting of shaft and hub, the rotational lock being implemented to release the twisting at least in a predetermined shaft-hub position.Type: ApplicationFiled: November 12, 2007Publication date: June 26, 2008Inventor: Gerd EISENBLAETTER

Publication number: 20070259611Abstract: The invention relates to a fastening system for mounting a roller-shaped tool on a drive shaft of a drive motor with the help of a fastening adapter comprising a hollow-cylindrical basic body which comprises in the interior a fastening apparatus for mounting on a drive shaft. A plurality of lamellae originate from the hollow-cylindrical basic body which are distributed about the cylinder axis and are spaced from one another by slits and which are each tilted in their direction perpendicular to the cylinder axis by a predetermined angle relative to the radial direction. The outside diameter of the fastening adapter can be reduced elastically by exerting pressure or the action of a shearing force in the direction of the tilting on the lamellae. The roller-shaped tool comprises a rigid cylindrical pass-through opening for this purpose whose inside diameter is smaller than the outside diameter of the fastening adapter in the relaxed state.Type: ApplicationFiled: April 11, 2007Publication date: November 8, 2007Inventor: Gerd Eisenblaetter
