DEVICE FOR TRANSFORMATION OF ROTARY MOTION INTO PROGRESSIVE (VERSIONS) Russian patent published in 2009 - IPC F16H25/20 F16H1/34 

FIELD: machine building.

SUBSTANCE: device for transformation of motion consists of screw, casing with covers and thread rolls. Thread rolls with ends installed in casing with ability of rotation around its axis and allows cylindrical threaded surfaces engaged to screw. At ends of each thread roll there are implemented spherical projections centres of which are located on axis of roller. At each cover there are implemented spherical angular clearances centres of which are also located on axis of corresponding roller. Additionally radius of spherical angular clearances in covers for 2-3% more than radius of spherical projections implemented on corresponding to it ends of each threaded roll. Device is outfitted by two pins which are provided for angular attitude of covers relative to casing.

EFFECT: increasing of output capability and durability of device, decreasing of its overall dimensions.
