PARALLELOGRAM STRAIGHT GUIDE MECHANISM Russian patent published in 2022 - IPC F16H21/26 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering. Parallelogram rectilinear guiding mechanism contains a three-crank articulated parallelogram and a four-link structural group kinematically connected to each other through rotational kinematic pairs with parallel axes of angular rotation. All three cranks are made in the form of double-hinged links of the same length and are installed in the same direction with each other. The rack is made in the form of a four-hinged triangular link, three hinges of which are located at the vertices of the mentioned triangle, and the fourth hinge is located in the middle of the base of this triangle. The connecting rod is made in the form of a triangle of a three-hinged link, which is equal to the triangle of the rack, and the four-link structural group is made up of three double-hinged links of the same length, connected at one end through a double hinge, and at the other end, respectively, attached to the rack and to the connecting rod through two double hinges and an additional a double-hinged connecting lever, the length of which exceeds the length of each of the three double-hinged links of the mentioned structural group.

EFFECT: simplification of the design, as well as elimination of dead uncontrolled positions of the mechanism.
