Abstract

The embodiments of the invention provide a balance block, a scroll compressor and an air conditioner. The balance block comprises a mounting part and a balance weight part; the mounting part is provided with a mounting hole used for mounting a crankshaft of the scroll compressor; the balance weight part is arranged on the mounting part and extends towards one side of the mounting part in the axial direction of the mounting hole, the balance weight part comprises a first arc surface and a second arc surface, the second arc surface is far away from the mounting hole compared with the first arc surface, the cross section of the first arc surface is a first arc section, and the cross section of the second arc surface is a second arc section; and the center of circle where the first arc section is located and / or the center of circle where the second arc section is located are / is spaced from the central axis of the mounting hole. According to the balance block, the scroll compressor and the air conditioner, the gas resistance moment borne by the balance block can be effectively reduced, the input power of the scroll compressor is reduced, the energy efficiency of the scroll compressor is improved, the weight proportion of the balance block in the whole dynamic and static design can be reduced, the vibration level of the scroll compressor is improved, and the reliability of the scroll compressor during high-frequency operation is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of scroll compressor equipment, in particular, to a balance weight, a scroll compressor and an air conditioner. Background technique [0002] Scroll compressor is a new type of positive displacement compressor, which is mainly composed of casing, static disk, moving disk, main frame, main balance weight, crankshaft, stator, rotor, auxiliary balance weight and auxiliary support. [0003] At present, when the main balance weight in the related art is applied, there is a problem that the gas resistance moment of the main balance weight is large during the operation of the scroll compressor, and the weight of the balance weight in the entire dynamic and static balance design is large, resulting in the input of the scroll compressor. The power increases and the high-frequency vibration is large, which will affect the energy efficiency of the scroll compressor and the reliability of high-freq...
