Abstract:
A rolling-body screw drive, comprising:a threaded spindle having an axis A of elongation; a threaded nut carried by the threaded spindle for movement axially therealong; a helically running threaded channel provided between an outer circumferential surface of the threaded spindle and an inner circumferential surface of the threaded nut; the threaded channel forming, together with an axially extending return channel in the nut which connects the two end regions of the threaded channel, an endless circulatory channel; an endless series of rolling bodies accommodated in the circulation channel; a deflecting element mounted on the threaded nut adjacent each of the two end regions of the threaded channel, each of the deflecting elements having therein a deflecting channel for transferring the rolling bodies between the threaded channel and the return channel and between the return channel and the threaded channel; a cutout in the threaded nut for accommodating each of the deflecting elements; at least one of the cutouts for accommodating the respective deflecting element being introduced into the threaded nut from the outer circumferential surface of the nut and being bounded by the threaded nut in both directions running essentially parallel to the longitudinal axis (A) of the threaded spindle; and the at least one respective deflecting element being secured on the threaded nut by fastening means running essentially parallel to the longitudinal axis (A) o f the threaded spindle.
