Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning compressors, and in particular relates to a dynamic and static disk structure of an air-conditioning compressor. Background Art

[0002] The scroll compressor is composed of two double-function equation-shaped movable and stationary scroll plates that engage with each other. During the working process of suction, compression and exhaust, the stationary plate is fixed to the frame, and the movable plate is driven by the eccentric shaft and restrained by the anti-rotation mechanism. It rotates in a plane with a very small radius around the center of the base circle of the stationary plate. The gas is sucked into the periphery of the stationary plate through the air filter element. As the eccentric shaft rotates, the gas is gradually compressed in the several crescent-shaped compression chambers formed by the engagement of the movable and stationary plates, and then continuously discharged from the axial hole of the central component of the stationary plate. The friction between the traditional movable and stationary plates is large, which is prone to loss. In addition, in order to ensure the sealing, the axial lengths of the barrel, the stationary vortex plate and the movable vortex plate must be equal, so the processing accuracy requirements are relatively high. Therefore, it is very important to obtain a movable and stationary plate structure of an air-conditioning compressor that overcomes the above-mentioned defects. Utility Model Content

[0021] Through the above technical solution, the contact areas between the first arc surface 1013 and the second arc surface 1022 and the dynamic chassis bottom plate and the static chassis bottom plate are small and linear, which can reduce contact friction, reduce kinetic energy loss, and reduce friction heat generation.

[0022] Preferably, the stationary vortex blade 1011 includes a stationary main body 1014 and a stationary telescopic body 1015. A first stop ring 1016 is provided at the end of the stationary telescopic body 1015. The first stop ring 1016 is positioned within a first chamber 1017 within the stationary main body 1014. A hollow rubber ring 103 is disposed between the stationary main body 1014 and the stationary telescopic body 1015. A first groove ring is defined on the stationary main body 1014, and a first mating ring is defined on the stationary telescopic body 1015 to mate with the first groove ring. Two first mounting locations 1018 for accommodating the hollow rubber ring 103 are formed between the first groove ring and the first mating ring.
