Publication number: 20120200050Abstract: A junction between two components of a tool system, that rotates about an axis of rotation, includes a conical seat, on the first component, coaxial to the axis of rotation and which is defined by an annular front face. The second component carries a coupling having a conical surface complementary to the conical seat and an annular end face resting against the front face. A tie bolt axially projects beyond the free end of the coupling pin and engages, in a cavity adjacent to the seat. The junction also has tensioning elements that are actuated from the exterior for mutually bracing the components, which are radially guided in the first component, and which act upon the tie bolt and are functionally linked with joint actuating means for adjustment between detached and tensioned positions. The tensioning elements include ejection portions that can be fitted with a rotatably received rolling element.Type: ApplicationFiled: April 17, 2012Publication date: August 9, 2012Inventors: Uwe KRETZSCHMANN, Jacek Kruszynski, Benno Spors, Wolfgang Bierl
