FOUR-BAR REDUCTION GEAR Russian patent published in 2007 - IPC F16H25/20 

FIELD: the invention refers to machine building namely to reduction gears of advance motion and may be used for increasing efforts on a driven shaft.

SUBSTANCE: the reduction gear has a driving slide-block and a driven slide-block, an intermediate unit and a post. The driven and the driving slide-blocks are connected with the intermediate unit through screw kinematic pairs and the intermediate unit itself forms with the post a rotating kinematic pair.

EFFECT: transformation of the advance motion of the driving slide-block through kinematic pairs into advance motion of the driven slide-block.
