However, in the above-mentioned patent, although the wear between the small end of the compressor connecting rod and the piston pin and the large end of the compressor connecting rod and the crank have been improved by increasing the oil passage, the connection between the small end of the compressor connecting rod and the crank is also damaged. The integrity of the piston pin and the big end of the compressor connecting rod and the crank force contact surface will cause grooves or holes to appear on the force contact surface. In the case of heavy load, the wear will be aggravated, and the working efficiency of the compressor will also be reduced. poor reliability

The invention relates to a connecting rod of a compressor, the compressor and a refrigerator, relates to the field of compressors, and mainly aims to reduce wear of the connecting rod of the compressor so as to improve the work efficiency and the reliability of the compressor. The technical scheme which is mainly adopted is as follows: the connecting rod of the compressor comprises a connecting part and a head part which is arranged on the connecting part, wherein the head part is the head part which is matched with a piston pin or the head part which is matched with a crank of a crankshaft, and the head part is provided with a shaft hole which is matched with the corresponding piston pin or the crank of the crankshaft; the wall of the shaft hole has a first region which is a stressed region, on the wall of the shaft hole, of the compressor which inhales; the connecting rod of the compressor further comprises an oil guide tank which is arranged in the first region. As the oil guide tank is arranged in the stressed region, on the wall of the shaft hole, of the compressor which sucks, the wall of the shaft hole is favorably lubricated, so that the wear is reduced; meanwhile, the damage on the contact surface by slotting is reduced, and intensified wear is not caused, so that the work efficiency and the reliability of the compressor are improved.
Description
technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor connecting rod, a compressor and a refrigerator. Background technique [0002] At present, the transmission mechanism of the reciprocating piston compressor of the refrigerator includes a crankshaft, a compressor connecting rod, a piston pin and a piston. The piston pin is inserted into the second shaft hole and the piston pin hole of the piston to connect the compressor connecting rod and the piston. Among them, the function of the connecting rod structure of the compressor is to transmit the torque of the crankshaft driven by the motor to the piston, and push the piston to perform periodic reciprocating motion. [0003] In general, the compressor connecting rod structure mainly includes: the small end of the compressor connecting rod, the connecting body of the compressor connecting rod and the large end of the compressor connecting rod. The small end of the c...
