Abstract
The utility model belongs to the technical field of compressors, and relates to a reciprocating type double-cylinder compressor. The reciprocating double-cylinder compressor comprises a crank case, a motor and an eccentric shaft stretching into the crank case and connected with a motor shaft. Air cylinders are arranged at two sides of the crank case symmetrically, a piston and a piston rod connected with the piston are arranged in the air cylinder, wherein the piston and the piston rod connected with the piston are matched with the air cylinder to act. The eccentric shaft inside the crank case is connected with the piston rod through a connecting device. A double cylinder structure is adopted by the reciprocating type double-cylinder compressor, and the reciprocating type double-cylinder compressor has the advantages of being good in balance, low in gravity center and small in vibration. A connecting rod and the piston rod are connected in a hinged mode, and therefore the piston rod at the connecting position side and the piston are enabled to carry out straight reciprocating motion relative to the air cylinder, and abrasion between the piston and the air cylinder is reduced. A bearing is fixedly arranged on the eccentric shaft, and bearings are arranged at motion auxiliary positions, friction can be effectively reduced, and service life of a driving mechanism is effectively prolonged.
