REVERSE MECHANISM FOR CONVERSION OF ROTARY MOTION INTO TRANSLATIONAL MOTION Russian patent published in 2020 - IPC F16H19/06 

FIELD: machine building.

SUBSTANCE: invention relates to the machine building. Reversible mechanism comprises slider guides, slider, first and second differential pulleys (DP) installed in housing and interconnected by rotation transmission with reversible drive, the first and the second deflecting pulleys installed on axes in the housing opposite to the corresponding DP, installed on the axes on the slider are two deflecting pulleys, a belt covering the deflecting and DP, located so that the belt branches covering the differential and deflecting pulleys are parallel to each other. Each belt branch interacts with one of DP or deflecting pulleys installed in the housing. Product of ratio of diameters DP and gear ratio of mechanical transmission of rotation has a value different from 1. Additionally, third and fourth DPs are installed on the slider, interacting with belt branches, respectively, connecting the first differential and the first diverting pulley installed in the housing, as well as the second differential and second deflecting pulley installed in the housing, wherein the third and fourth DP are connected to each other by mechanical rotation transmission.

EFFECT: higher rigidity and accuracy of positioning reversing mechanism, as well as higher smoothness of movements.
