The invention relates to a ball screw which comprises a threaded nut (12) with grooves (14) for rolling bodies (34), a threaded spindle (36) with grooves (40) for rolling bodies (34), and an intermediate bush (24) which is interposed between the threaded nut (12) and the threaded spindle (36). Said intermediate bush (24) comprises grooves (26) which face the threaded nut (12) and which are adapted to the grooves (14) of the threaded nut (12), rolling bodies (16) being guided in these grooves. The intermediate bush (24) comprises grooves (32) which face the threaded spindle (36) and which are adapted to the grooves (40) of the latter, rolling bodies being guided in these grooves. A first threaded element (25) which is configured by means of the grooves (14, 26) of the threaded nut (12) and the intermediate bush (24) facing each other, and a second threaded element (35) which is configured by means of the intermediate bush and the threaded nut facing each other work in opposite directions. |
