SPATIAL MECHANISM WITH CIRCULAR LEVER BASE Russian patent published in 2018 - IPC B25J11/00 B25J17/02 F16H21/04 F16H21/02 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to mechanisms used in the art for obtaining a predetermined motion of a driven member. Inside the circular guide is installed a flat lever mechanism of the base, which includes a leading link forming three rotational kinematic pairs with a guide, located in the center and opposite in diameter to the circular guide, the carriages are hingedly connected to additional connecting rods connected by means of rocker arms to the main connecting rods connected in turn to the driving link, while all kinematic pairs of links of the mechanism of the base are made with vertical axes, and the main and additional connecting rods on the side of the connection with the rockers have cellular grooves, in which fixers with different diameters of cross-section are fixed, fixed by pins.

EFFECT: object of the invention is to create such a parallel structure mechanism in which the movement of the platform could be controlled by a single leading link.
