The hub (3) has a first and second, parallel, end surface between which is a through-hole centered on a lengthwise axis (2) and which has a first section (6). A support disc (11) has a continuos hole (12). A shaft (14) has an outer surface section (15) centered on the length axis. A threaded hole (18) centered on the lengthwise axis and starting from a shaft's end surface(17). A clamping screw (19) has a head (20) and threaded shaft (22) and, starting from the second end surface of the hub, is screwed through the hole in the support disc into the threaded hole. A nut (23) is fixed between the support disc and the shaft's end surface with clearance. |
