FIELD: machine building.
SUBSTANCE: invention relates to a nut used as a screw of a lead screw or similar electric actuator. Nut comprises a plurality of plate elements, in which through holes of almost identical diameter are made. In each of plate-like elements there formed are multiple protrusions of thread profile projecting inside through hole and spaced at the specified angular gap from each other. Plate-like elements are layer-by-layer laid on each other so that through holes are arranged practically coaxially to each other. Outer circumferential sections of each plate-like elements are connected to each other as a result of welding in state after layer-by-layer application of plate-like elements on each other, at which projections of thread profile of each of plate-like elements are continuation of each other in direction of nut axis.
EFFECT: invention is aimed at simplification of parameters monitoring, as well as reduction of time of nut processing and manufacturing.
