FIELD: mechanical engineering.
SUBSTANCE: invention relates to mechanical systems of parallel design. A two-moving reconfigurable spherical mechanism with a circular guide includes a rack and a platform, between which three kinematic chains are installed, two of which include lower and upper levers, and the third chain consists of a rod and a fork. The mechanism rack is made in the form of a circular guide with teeth cut on it, on which carriages with gear wheels are placed, whereas the carriages form rotational hinges with lower levers, and connecting rods are installed between the upper levers and the platform by means of rotational hinges. The geometric axes of the hinges intersect at the centre of the rotational hinge between the yoke and the platform, and the rod is connected to the circular guide by means of a translational hinge. The lower and upper levers are flat.
EFFECT: expansion of the field of application.
