SLIDE NUT OF LINEAR MOVEMENT MECHANISM Russian patent published in 2015 - IPC F16H25/20 F16H25/00 

FIELD: machine building.

SUBSTANCE: slide nut of linear movement mechanism contains the basic half-nut (1) and auxiliary semi-nut (2), in which open coaxial holes are made, which are equidistant mutually and from the centre, this holes are inserted by the cylindrical pins (3), connecting the half-nuts. Between viaholes on neighbouring ends of half-nuts the coaxial cylindrical deepenings are located, where the cylindrical compression springs (4) are inserted. At the centre of deepenings in the auxiliary nut the threaded holes are made, and at the centre of deepenings in the main half-nut - the viaholes, with the diameter less than the diameter of deepenings, where the screws (5), connecting half-nuts and regulating the compression of springs (4), are installed.

EFFECT: due to use of springs located between half-nuts, at reverse motion the clearance between coils of the slide screw and slide nut, caused by their wear, is automatically compensated.
