FIELD: machine building.
SUBSTANCE: invention relates to motion transmission mechanisms. Opposite crank mechanism comprises cylinder with piston and rod. Piston is rigidly fixed with a forked rod. Arms of the forked stock are connected to coaxial axes having the possibility of performing a complex translational-rotational movement. Coaxial axes have two diametrically oppositely directed cranks, spaced apart in axial directions. Mid cranks are connected by crank pin. Connecting rod with the swinging axis in the housing is located opposite to the working cylinder side from the main shaft axis. Connecting rod axis in the upper dead point and the lower dead point is located on the extension of the straight line of the cylinder axis. Cranks of the main shaft are connected by axes of rotation with cranks of coaxial axes, and the length of the connecting rod exceeds the radius of the crank of the main shaft by more than two times.
EFFECT: mutual conversion of rotational and reciprocal motion is achieved.
