The invention relates to mechanisms used in industrial and household units where transformation of reciprocating motion to rotary one in direct and reverse directions is needed, mostly in combustion engines. The crank mechanism includes a crankshaft, con-rod, piston, two coaxial piston pins and support insert placed between those. The piston pins and the support insert are turned one to another with their conical end surfaces, respectively, with formation of spaces where solids of revolution are placed, at that the pins are installed with possibility of motion and fixation in axial direction. The invention makes it possible to decrease dynamical load of the units of the crank mechanism due to removal of possibility of skew, to increase reliability, durability and smoothness of operation. |
