SIX-LINK MECHANISM Russian patent published in 2008 - IPC F16H21/46 

FIELD: engines and pumps.

SUBSTANCE: six-link mechanism relates to machine building, particularly to multi-link link mechanisms designed to transform the drive link rotary motion into translation of the driven drawing point. The link mechanism incorporates four dogs forming two dyads interlinked by two intermediate links. The mechanisms links are linked in pairs by single-way hinges. The first dyad first dog makes a drive link. The first dyad hinge axes are perpendicular to those of the second dyad. The first dyad outer hinge axes are located in the second dyad plane. The drawing point is coupled with one of the mechanism links. The first dyad second dog is fixed. The second dyad first dog is the mechanism driven link. The second dyad inner link is located in the first dog central point, the said dog free end representing a drawing point. Every intermediate link is aligned with the first dyad outer hinge axis, the first dyad first dog length being smaller that that of its second dog. The second dyad second dog length a makes a length of the second dyad first dog. The sum of the second dyad second dog length and a half the length of the first dog exceeds that of lengths of the first dyad dogs, the intermediate link lengths being equal.

EFFECT: high accuracy of straight line reproduction thanks to redistribution of links functions.
