Description
Technical field
The utility model is related to refrigeration compressor spare and accessory parts field, especially a kind of to reduce the magnetic of frequency-changeable compressor noise
Steel rotor structure.
Background technology
Because the magnetic steel rotor structure of current frequency-changeable compressor is fixed, cause inertia and intrinsic frequency that its rotor is rotated
Rate is also fixed, and the vibration of compressor and noiseproof feature can only be changed by compressor global design, add compressor
Design difficulty.
The content of the invention
There is provided one kind for vibration and the inconvenient technical problem of noiseproof feature regulation of the utility model for the existing compressor of solution
The magnetic steel rotor structure of the simple in construction, total quality of adjustable magnetic steel rotor and centroid position.
It is to solve above-mentioned technical problem the technical solution of the utility model：It is a kind of to reduce the magnetic of frequency-changeable compressor noise
Steel rotor structure, including magnet ring, bottom end cover, upper end cover, rotor core, rivet, the bottom end cover are arranged on rotor core bottom,
The upper end cover is arranged at the top of rotor core, and the rotor core is positioned with magnet ring by upper end cover, and is fixed by rivet,
It is characterized in that：It is provided with outside the upper end cover on regulating block, the outer ring of the regulating block and is provided with counterweight hole, it is described to match somebody with somebody
Balance rivet is provided with repeated hole hole.
The external diameter of the regulating block is 48~54mm, and thickness is 1.5~10.5mm.
The quantity of the counterweight hole is less than 50.
The utility model has following technique effect：The magnetic steel rotor can freely be adjusted rotor and turned within the specific limits
Dynamic inertia, rotor intrinsic frequency, it is possible to be adjusted after the completion of compressor other parts designs, and then improve compressor
Vibration and noiseproof feature, so as to reduce compressor global design difficulty.And can be assembled in production after compressor crank shaft,
The dynamic balancing of adjusting rotation axle system, improves product quality and production stability.
Brief description of the drawings
Fig. 1 is the structural representation of magnetic steel rotor in the prior art；
Fig. 2 is the structural representation of the utility model magnetic steel rotor.
Embodiment
Below in conjunction with the accompanying drawings 1,2 and embodiment the content of the invention of the present utility model is described in detail it is as follows：
Reference picture 1,2, it is a kind of to reduce the magnetic steel rotor structure of frequency-changeable compressor noise, including magnet ring 1, bottom end cover 2, on
End cap 3, rotor core 4, rivet 5, by rivet 5 by bottom end cover 2 and upper end cover 3 be separately fixed at rotor core 4 bottom and
Top, the rotor core 4 and upper end cover 3 are socketed in inside magnet ring 1, and the bottom end cover 2 is protruded at the top of magnet ring 1, described
It is bonded with outside bottom end cover 2 on regulating block 6, the outer ring of the regulating block 6 and is stamped with counterweight hole 8, can in the counterweight hole 8
Riveting has balance rivet 7.
The external diameter of the regulating block is 50mm, and thickness is 6mm.
The quantity of the counterweight hole is 25.
Operation principle of the present utility model：Regulating block 6 is installed outside upper end cover 3 to be determined in compressor total system
Afterwards, within the specific limits by changing external diameter, the thickness of regulating block 6, to change rotary inertia, the intrinsic frequency of rotor, so that
Reduce the vibration under frequency-changeable compressor specific rotation speeds and noise.And balance can be installed additional in the counterweight hole 8 of regulating block 6
Rivet 7 is used for the dynamic balancing for adjusting rotation system, so as to solve not adjusting dynamic during the production of frequency conversion refrigerator compressor rotation system
The defect of balance.
Better embodiment of the present utility model is illustrated above, but the invention be not limited to it is described
Embodiment, those skilled in the art can also make a variety of equivalent changes on the premise of without prejudice to the utility model spirit
Type or replacement, these equivalent modifications or replacement are encompassed within the application Seeking for Right limited range.
