Abstract

The invention discloses a crank-link mechanism for a refrigeration compressor. The crank-link mechanism comprises a crank shaft, an integral link, a crank shaft box, a piston, a piston pin, a positioning pin and a link stop pin, wherein the thickness of the integral link is less than the height of the inner cavity of the piston; the left end of the integral link is sleeved on the upper end of the crank shaft; the right end of the integral link is arranged in the inner cavity of the piston; the piston pin is arranged at the right end of the integral link and is arranged in an opening arranged on the piston; the positioning pin is arranged at the lower end of the piston and is used for connecting the piston with the piston pin; and the link stop pin is fixedly arranged on the piston pin above the right end of the integral link rod. The compressor provided with the crank-link mechanism provided by the invention has the advantages that a link installation abdication groove is not required to be arranged in the air cylinder hole of the crank shaft box, so that the deformation caused by arranging the link installation abdication groove is not required to be arranged in the air cylinder hole is avoided, the stability of performance of the compressor is ensured, and the compressor is simple and reliable in structure and low in manufacturing cost.

Description

technical field [0001] The invention relates to a crank-link mechanism applied to a refrigeration compressor. Background technique [0002] Existing refrigeration compressors generally use a reciprocating crank-connecting rod mechanism. figure 1 Shown is a kind of crank-connecting rod mechanism commonly used for refrigeration compressors at present, including crankshaft 1, integral connecting rod 2, crankcase 3, piston 4 and piston pin 5, and piston 4 is installed in the cylinder of crankcase 3 In the hole, the piston pin 5 is connected with the integral connecting rod 2. When the compressor is running, the crankshaft 1 rotates, and the connecting rod 2 drives the piston 4 to reciprocate. Since the connecting rod 2 adopts an integral structure, in order to ensure the smooth progress of the assembly, a connecting rod installation relief groove 6 needs to be provided on the crankcase 3 . And because of the existence of the connecting rod installation relief groove 6, the cy...
