MOBILE ELEMENT MOVEMENT DEVICE Russian patent published in 2020 - IPC B23Q5/40 B23Q5/56 F16H25/20 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, namely, to screw-nut transmissions with drive screw and driven nut. Proposed device comprises helical pair with lead screw engaged with fixed element. Nut with possibility of rotation is inserted into through cylindrical hole of insert and is made in form of cylinder with radial threaded hole for screw. Insert is installed with possibility of rotation relative to the movable element. Lead screw is connected to the fixed element by means of an axis which is inserted with the possibility of rotation into the through cylindrical hole of the additional insert and is made in the form of a cylinder with a radial hole at the end of the screw. Movable and fixed elements are made in the form of a bracket with two lugs. Each of the inserts with its cylindrical protrusions is inserted into holes of the lugs of the corresponding bracket with possibility of rotation.

EFFECT: as a result, expansion of the application area of the device is provided with provision of its operability preservation at angular displacement of the longitudinal axis of the screw to the required movement direction of the movable element.
