FIELD: mechanical engineering. ^ SUBSTANCE: roller-screw gearing comprises screw (1) with closed screw groove, unmovable wheel (4), driven wheel (6), and rollers which are in contact with them. The rollers reciprocates along the axis of the gearing. The inner roller moves along the closed screw groove. Outer roller (5) rotates driven wheel (6). Axle (3) between the rollers rolls around the teeth of unmovable wheel (4) whose teeth are cut in the face and have screw cross-sections. ^ EFFECT: reduced wear and enhanced efficiency. ^ 5 dwg |
