The invention relates to mechanisms used in industrial and household units where it is needed to transform reciprocating motion to rotary one in direct and reverse directions, mostly in combustion engines. The crank mechanism includes a crankshaft, con-rod, piston and two coaxial piston pins turned to each other with their conical end surfaces with formation of space where solid of revolution is placed. At that the pins are installed with possibility of displacement and fixation in axial direction. The invention makes it possible to decrease dynamical load on the units of the crank mechanism due to removal of possibility of skew, to increase reliability, durability and smoothness of operation. |
