FIELD: machine building.SUBSTANCE: screw gear contains the screw (1) and the nut (2). One of elements, the screw or the nut, is implemented in the form of the cylindrical spring interfaced to a rigid thread of another element. Meanwhile the element thread pitch in the form of cylindrical spring exceeds the rigid thread pitch of the second element. The spring (1) has the turn pitch regulation device. The screw-spring can have circular or curvilinear shape with the axis of variable curvature and direction, for example, sinusoid.EFFECT: expansion of application field.2 cl, 6 dwg |
