FIELD: transport. ^ SUBSTANCE: invention relates to aircraft engineering, particularly, drone aircraft aerodynamic surface control drives, and may be used in both development of new drone aircraft and updating used aircraft. Proposed steering drive comprises engine, reduction gear consisting of screw gear accommodated in reduction gear box, rack gear made up of carriage rack engaged with sliding nut, and control surface shaft toothed sector. Note here that steering drive is equipped with blocker of flexural deformations in screw gear made up of two pairs of antifriction bearings fitted on sliding nut carriage to rest on reduction gearbox. Reduction gearbox is made up of two lengthwise flat guides making the angle of 120Ç160 between them in the area of said two pairs of antifriction bearings. Said bearings are fitted on sliding nut carriage to control their pressing to said lengthwise flat guides with the help of, for example, cams. ^ EFFECT: higher reliability and faster operation. ^ 2 cl, 3 dwg |
