ARTICULATION LINKAGE Russian patent published in 2017 - IPC F16H21/48 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly, to articulation linkages. Articulation linkage includes post, drive and driven cranks, two crank rods and intermediate link, which are connected by rotators. Mechanism links have angular and linear parameters, which satisfy equality of l₂/sinα₂ = l₃/sinα₃ = l₄/sinα₄ = l₅/sinα₅ = l and inequality α₃<α₅<α₄<α₂, as well as α₆=α₂+α₄, l₆=l₂+l₄. Here designated lengths of: l – posts, l₂ – driving crank, l₃ – driven crank, l₄ – driving crank crank rod, l₅ – driven crank crank rod, l₆ – intermediate link; intersection angles: α₂ – driving crank, α₃ – driven crank, α₄ – driving crank crank rod, α₅ – driven crank crank rod, α₆ – intermediate link.

EFFECT: achieved is design simplification.
