Abstract
The utility model relates to a rotary compressor noise reduction structure, which comprises a shell and a small-diameter stator component, wherein the small-diameter stator component comprises a stator core and a winding, a lining is arranged between the small-diameter stator component and the shell, the lining is a casting, the height of the lining is four fifths of the height of the stator core, and the connection modes between the small-diameter stator component and the lining as well as between the lining and the shell are connected in a hot-sleeve matching mode; the advantage is that the vibration noise caused by the deflection deformation of the rest parts caused by the output can be reduced; compared with the original large-outer-diameter structure, the noise can be reduced by 5dB (A).
Description
Technical Field
The utility model relates to a compressor field specifically is a rotary compressor noise reduction structure.
Background
The shell and the stator assembly of the existing rotary compressor are usually fixed directly by hot charging, and the periodic radial and circumferential deformation vibration generated by the stator core generates electromagnetic noise under the action of electromagnetic force. The large-outer-diameter structure of the existing compressor is formed by directly welding a large-diameter stator assembly with a shell, wherein the large-diameter stator assembly is in contact with the shell, and the stator core of the structure has a large diameter and cannot play a good role in reducing electromagnetic noise.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a rotary compressor noise reduction structure can reduce the electromagnetic noise that stator core warp the vibration and send effectively.
In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a rotary compressor noise reduction structure, includes the shell, its technical essential is: still including minor diameter stator module, minor diameter stator module is inside including stator core and wire winding, is provided with a bush between minor diameter stator module and the shell, and the bush is the foundry goods, and the bush height is four fifths of stator core height, and the connected mode between minor diameter stator module and bush, bush and the shell is the hot jacket complex mode and is connected.
The utility model has the advantages and beneficial effects that: the diameter of the optimized stator core of the compressor structure is reduced, so that the vibration noise generated by unbalanced electromagnetic force of a magnetic circuit can be reduced, the diameter of the stator can be reduced, the output power can be reduced, and the vibration noise caused by the deflection deformation of other parts caused by output can be reduced; compared with the original large-outer-diameter structure, the noise can be reduced by 5dB (A).
