Abstract

The invention discloses a compressor connecting rod and a production method thereof. The compressor connecting rod comprises a connecting rod, a first connecting end and a second connecting end, wherein the first connecting end and the second connecting end are respectively arranged at the two ends of the connecting rod, the radial dimension of the first connecting end is larger than the radial dimension of the second connecting end, and the outer wall surface of the first connecting end is covered with an oxide film layer. According to the compressor connecting rod of the embodiment of the invention, by covering the first connecting end with larger radial direction with the oxide film layer, the oxide film layer covers the basal body surface of the first connecting end and is densely and firmly attached, vapor and corrosive medium in the environment are difficult to enter the internal part of the first connecting end, not only a good antirust function is achieved, but also a certain anticorrosive effect is obtained, the voids in parts can be closed, and the hardness and the wear resistance of the parts are improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor connecting rod and a preparation method thereof. Background technique [0002] The connecting rod is one of the main moving parts of the pin-shaft refrigeration compressor. The main function of the connecting rod is to convert the rotary motion of the crankshaft into the reciprocating motion of the piston, so as to achieve the purpose of compressing the refrigerant medium. The connecting rod is an iron-based powder metallurgy product, including a large end, a shaft, and a small end. Low. The connecting rod has been subjected to huge inertial force and gas pressure due to high-speed operation for a long time, and the phosphating layer on the surface is easy to wear and fall off, which seriously affects the service life of the compressor. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems at leas...
