FIELD: engines and pumps.
SUBSTANCE: invention is related to machine building, in particular, to mechanisms for transformation of reciprocal motion to rotary motion and may be used, for instance, in internal combustion engines, pumps and compressors. According to invention, mechanism comprises actuator, in particular case, piston hingedly fixed to stem, which is connected in guide and is hingedly fixed to rocker. Every arm of rocker is hingedly connected to couplers, which in its turn are hingedly connected to two synchronously rotating crank shafts. Besides, every end of rocker is connected to appropriate shaft by means of single coupler, and couplers may each move in their plane.
EFFECT: simplification of design, reduction of mass and dimensional parameters and increase of durability and reliability and also in provision of possibility to adjust characteristics of mechanism torque, speed and value of actuator stroke, without change of crankshafts radiuses.
