Abstract

The invention provides a piston assembly, a reciprocating compressor and a refrigerator. The piston assembly comprises a piston pin assembly used for connecting a piston and a connecting rod. The piston pin assembly comprises a piston pin, the piston pin is arranged in a piston pin hole, and at least two mounting positions are arranged in the piston pin hole so that the piston pin can be located at different positions in the axial direction of the piston. One end of the connecting rod is sleeved on the piston pin. According to the piston assembly, the piston pin is adjusted to be located at different positions in the piston pin hole, the piston assembly can meet the use requirements of pistons of different types and displacements, and therefore the universality is greatly improved.

Description

technical field [0001] The application belongs to the technical field of refrigerators, and in particular relates to a piston assembly, a reciprocating compressor and a refrigerator. Background technique [0002] At present, with the improvement of living standards and quality, the overall size of fully enclosed reciprocating compressors is getting smaller and smaller. At the same time, with the increase in labor and material costs, refrigerator manufacturers are in fierce price competition, and the price requirements for compressors are getting lower and lower. , low-cost compressors have great competitive advantages. In this competitive environment, the profit margins of compressor manufacturers are further compressed, and the miniaturization of compressor dimensions, reduction of material costs, and reduction of parts processing costs are carried out. Reduce costs and increase efficiency. [0003] Conventional piston assembly structure, such as Figure 11 As shown, the p...
