Abstract

The invention discloses a vortex compressor with a gasket pin structure. The vortex compressor with the gasket pin structure comprises a machine shell (1), a static disk (2), a dynamic disk (3), an eccentric sleeve (4), a crankshaft (5) and a front cover (6), and is characterized in that pins (13) are arranged on the end surface, opposite to the front cover (6), of the dynamic disk (3); a gasket (14) with the thickness of 3 to 5.5 mm, the hardness of HRC 40 to 50, the material of 40Cr or 20CrMo is arranged on the end surface, opposite to the dynamic disk (3), of the front cover (6); circular holes (12) with the same number as that of the pins (13) are formed in the gasket (14); the height H of each pin (13) is equal to 80 to 95 percent of the thickness of the gasket (14); the gasket (14) is positioned on the end surface, opposite to the dynamic disk (3), of the front cover (6) through a positioning pin (19); the positioning pin (19) is in clearance fit with the corresponding positioning hole (14a) in the gasket (14); the fit clearance between the positioning pin (19) and the positioning hole (14a) is 0.045 to 0.127. The vortex compressor with the gasket pin structure has the advantages of simple structure, light weight and convenience in installation.

Description

technical field

[0001] The invention relates to a scroll compressor, in particular to a scroll compressor with simple structure and high transmission efficiency, specifically a scroll compressor with ring pin structure. Background technique

[0002] As we all know, in scroll compressors (electric or conventional power), in order to make the rotor plate swing in the plane driven by the crankshaft, it is necessary to restrict the rotor disc from rotating. Currently, the commonly used methods include the structure of steel balls plus fixed ball rings and There are two types of ring pin structures. Chinese patents 2006100405145 and 2008100236786 all use the structure of steel balls and fixed bead rings. In order to ensure wear resistance, stop rings need to be installed on the end face and front end surface of the moving disc, and because the steel The volume of the ball is large, which increases the volume and weight of the scroll compressor; in addition, because the fixed bead...
