Problems solved by technology

[0002] At present, in the transmission mechanism of traditional reciprocating piston compressors, the force transmission method is through the crankshaft: a crank pin → a connecting rod → a crosshead → a piston transmission method, and several pistons need to be equipped with the same number of crossheads , connecting rod, and crank pin, the structure is complex and the production cost is high; because the piston is not on the same axis, there is a crank between the crank pins, which will form bending stress on the crank, the crankshaft structure is complicated, and the production cost is high; the piston force cannot be offset , the corresponding components have large dimensions, resulting in great waste, how to solve the above technical problems has become the direction of efforts of those skilled in the art

Abstract

The invention discloses a double-way cross-shaped head transmission mechanism for a reciprocating piston type compressor. The double-way cross-shaped head transmission mechanism for the reciprocatingpiston type compressor comprises a crankshaft, a double-way cross-shaped head and a connecting rod, the crankshaft is connected with a power source of the compressor, the double-way cross-shaped headis perpendicular to the crankshaft, the two ends of the double-way cross-shaped head are connected with pistons, and the connecting rod is connected between the double-way cross-shaped head and the crankshaft. The power source of the compressor drives the crankshaft to do rotating motion, the crankshaft drives the connecting rod, the connecting rod pulls the double-way cross-shaped head to do reciprocating motion, two independent cross-shaped heads are rigidly connected together through the double-way cross-shaped head, the two pistons are driven to do reciprocating motion for gas compression,the two pistons are rigidly connected through the double-way cross-shaped head transmission mechanism, the motion directions are in the same axis, the piston force is counteracted, the acting force on a crank pin is reduced, and the reliability of a unit is improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a bidirectional crosshead transmission mechanism for reciprocating piston compressors. Background technique [0002] At present, in the transmission mechanism of traditional reciprocating piston compressors, the force transmission method is through the crankshaft: a crank pin → a connecting rod → a crosshead → a piston transmission method, and several pistons need to be equipped with the same number of crossheads , connecting rod, and crank pin, the structure is complex and the production cost is high; because the piston is not on the same axis, there is a crank between the crank pins, which will form bending stress on the crank, the crankshaft structure is complicated, and the production cost is high; the piston force cannot be offset , and the corresponding parts have large dimensions, resulting in great waste. How to solve the above technical problems has become the direct...
