  • Patent number: 6561053
    Abstract: A rolling-body screw drive (10) comprises a threaded spindle and a threaded nut (12) enclosing the threaded spindle. A helically running threaded channel (16) is provided between an outer circumferential surface of the threaded spindle and an inner circumferential surface (12a) of the threaded nut (12). The threaded channel (16) forms, together with a return channel (22) in the nut (12) which connects the two end regions (16a, 16b) of the threaded channel (16), an endless circulatory channel (24) in which an endless series of rolling bodies is accommodated. Each of the two end regions (16a, 16b) of the threaded channel (16) is assigned a deflecting element (18) which is retained on the threaded nut (12) and has a deflecting channel (20) for transferring the rolling bodies between the threaded channel (16) and the return channel (22). At least one of the deflecting elements (18) is made up of at least two deflecting-element parts (26, 28) which together bound the deflecting channel (20).
