Abstract

The invention provides a low-compression-ratio and fully-oilless scroll air compressor assembly, belongs to the technical field of compressors and particularly relates to the low-compression-ratio and fully-oilless scroll air compressor assembly. The low-compression-ratio and fully-oilless scroll air compressor assembly provided by the invention has the advantages of good leak tightness and stability. The low-compression-ratio and fully-oilless scroll air compressor assembly comprises a host shell and a moving scroll disc and has the structural features that the host shell is connected with the moving scroll above the internal middle part of the host shell through a three-axis autorotation preventing module, a static scroll disc is arranged at the upper end of the moving scroll disc, and the edge of the static scroll disc is connected with the upper end of the edge of the host shell; a main drive bearing mounting groove is formed in the middle part of the lower end face of the moving scroll disc, a motor front bearing mounting hole is formed in the middle part of the host shell corresponding to the main drive bearing mounting groove, the lower end of the host shell is connected with the upper end of a stator shell body, the lower end of the stator shell body is connected with a motor after-frame, and the periphery of the motor after-frame, the periphery of the host shell and the periphery of the static scroll disc are connected through vertical fasteners.

Description

technical field [0001] The invention belongs to the technical field of compressors, in particular to a low compression ratio oil-free scroll air compressor assembly. Background technique [0002] At present, the scroll compressor products available on the market are mainly concentrated in the field of refrigeration and air conditioning, but the oil-free series scroll air compressors are rare, the main reason is that the problem of gas leakage is difficult to solve. Compared with refrigeration scroll compressors, oil-free series products have stricter requirements on meshing clearance and working stability, especially the larger the compression ratio, the larger the leakage ratio and frictional heat, and the lower the working efficiency , which increases the difficulty of marketization of such products. Contents of the invention [0003] The present invention aims at the above problems and provides a low compression ratio oil-free scroll air compressor assembly with good s...
