CRANK MECHANISM AND RECIPROCATING COMPRESSOR USING IT

摘要

PURPOSE: A crank mechanism and a reciprocating compressor using the same are provided to improve mechanical strength, and to stabilize a reciprocating motion of a piston when the piston is rotated with high-speed. CONSTITUTION: A crank mechanism comprises an inclined plate, a rising rod(2), an auxiliary rod(3), and a lifting unit(4). The inclined plate is coupled to a power shaft(110), and is rotated in the bottom of a cylinder(130). The rising rod is risen by the rotation of the inclined plate, and pushes up a piston(120) coupled to the top end of the rising rod. The lifting unit descends the rising rod when the auxiliary rod is ascended, and ascends the rising rod when the auxiliary rod is descended.
