Rolling screw and nut assembly comprising a screw (V) and a nut (E) with multiple threads, of identical pitch. The consecutive threads (I, II) have, on the screw (V) and on the nut (E), intervals (a+ delta , a- delta ) varying in repetitive fashion with a period corresponding to the pitch, the change in mounting position of the screw (V) with respect to the nut (E) allowing, with the same constituent elements, the contact conditions of the roller elements (B) with the threads of the nut (E) and of the screw (V) to be varied. …<??>Application: especially to screw and nut assemblies with balls and with a fast pitch. …<IMAGE>… |
