STRAIGHTLY DIRECTING PIVOT MECHANISM Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: pivots 5,8 that connect crank 2 with stand 1 and rockers 3 with connecting rod 4 can move in one direction only. Pivot 7 that connects crank 2 with connecting rod 4 is spherical. Pivot 6 that connects rocker 3 with stand 1 can move in two directions and is mounted at the point of intersection of the plane of rotation of crank 2 with the straight line that passes through the drawing point of connecting rod 4 parallel to the axis of pivot 5. One of the mutually perpendicular axes of pivot 6 is parallel to the axis of pivot 8. The other one is parallel to the axis of pivot 5. The axis of pivot 8 is perpendicular to connecting rod 4 and rocker 3. When crank 8 rotates the drawing point of connecting rod 4 moves along a straight line. EFFECT: enhanced efficiency. 1 dwg
