FIELD: lever-type transfer devices converting the rotary motion of drive crank into rectilinear motion of driven slider. SUBSTANCE: slider-crank mechanism includes rack with rectilinear guide, crank and rocker arm articulated with this rack, slider mounted in guide, blade articulated with slider, rectilinear double-arm connecting rod; for connecting the crank with connecting rod, blade with slider and connecting rod, use is made of spherical joints; used for connecting the rocker arm with rack, use is made of two-position hinge mounted at point of intersection of plane of rotation of crank with longitudinal axis of slider guide; axis of hinge connecting the crank with rack is parallel to longitudinal axis of slider guide; one of mutually perpendicular axes of hinge connecting the rocker arm with rack is parallel to axis of hinge connecting the rocker arm with connecting rod; other axis coincides with longitudinal axis of slider guide. EFFECT: enhanced reliability. 1 dwgs |
