Problems solved by technology

However, reducing the eccentricity of the crankshaft will cause the meshing gap between the moving scroll and the entire involute of the fixed scroll to increase, which will increase the internal leakage between the moving scroll and the fixed scroll , resulting in a decrease in the overall performance of the scroll compressor

Abstract

The invention relates to the technical field of air-conditioning equipment, in particular to a scroll tooth with a scroll tooth profile structure, a scroll disk structure and a scroll compressor. The outer profile line and the inner profile line of the scroll tooth profile structure are respectively composed of involutes, and the outer profile line and the inner profile line are arranged together to form the tooth wall of the scroll tooth, and its thickness is along the center direction of the scroll tooth. The outer edge gradually becomes larger; Δt is the change value of the tooth wall thickness of the scroll tooth, and the tooth wall thickness at the center of the scroll tooth is 2Δt smaller than the tooth wall thickness at the outer edge; the moving vortex of the scroll structure The scroll tooth profile structure is provided on the disk, and the fixed scroll profile line composed of involute and meshed with the scroll tooth profile line structure is provided on the fixed scroll disk. The fixed tooth profile line and the scroll tooth profile line The structures are staggered by 180°; the scroll compressor includes the scroll structure. The invention can not change the eccentricity of the crankshaft, but can reduce the stress of the vortex caused by temperature and pressure, improve the strength, keep the meshing gap unchanged, and avoid internal leakage.

Description

Technical field [0001] The present invention relates to the technical field of air-conditioning equipment, and in particular to a scroll tooth, a scroll structure and a scroll compressor with a scroll tooth profile structure. Background technique [0002] Scroll compressors are widely used in air-conditioning and heat pump systems due to their high efficiency, small size, light weight and stable operation. The working principle of the existing scroll compressor is that the moving scroll and the fixed scroll cooperate with each other, and the refrigerant is sucked, compressed and discharged continuously in the scroll driven by the crankshaft. During the compression process of the refrigerant, the pressure and temperature from the outside to the center of the scroll gradually increase, and the pressure and temperature are the highest at the center side. Under the action of the refrigerant, the deformation of the scroll wall on the center side of the scroll is the largest, and the ...
