Abstract
The utility model discloses a non-magnetic high manganese steel balance weight for a sealed compressor and belongs to the technical field of sealed compressor accessories. The non-magnetic high manganese steel balance weight for the sealed compressor comprises a circular ring structure and a balance weight body fixed to the circular ring structure. The balance weight body and the circular ring structure constitute a step combined structure. The non-magnetic high manganese steel balance weight for the sealed compressor is simple in structure and reasonable in design. A circle of riveting holes are formed in the balance weight, so that eccentricity generated when the balance weight rotates is transmitted to rivets arranged in all the riveting holes, the load intensity is relieved and the damage to a rotor iron core is reduced. The outer side of the circular ring structure of the balance weight is provided with a plurality of cut side structures according to the thickness of the outer side of the circuit ring structure of the balance weight, so that the material utilization amount of the balance weight and cost are reduced. Due to the fact that a plurality of arc surface structures are arranged on the inner side of the circular ring structure of the balance weight, the strength of the riveting hole portions is improved, and the balance weight production operation performance of the casting technique production is improved. Each riveting hole is of a recessed structure, so that each assembled rivet is embedded into the balance weight, and noise caused by airflow friction is reduced.
Description
Technical field
The utility model belongs to hermetic compressor accessory technical field, is specifically related to hermetic compressors without magnetic high manganese steel equilibrium block.
Background technique
The noise that the vibration of compressor that the noise of hermetic compressor is caused by the electromagnet pull of motor electromagnetic noise and motor itself greatly forms forms, the electromagnet pull of motor mainly acts on motor at the motor gas-gap magnetic Field Coupling, from compressor arrangement, motor and compressor gas compression member distance (being that acting force arm length is longer) far away, the vibration noise that electromagnet pull causes by compressor housing and live axle transmission is larger, therefore, as optimal design, the common claimed structure compactness of hermetic compressor is short, particularly frequency-changeable compressor need to be designed to short as much as possible, in order to be conducive to reduce compressor noise.
The compressor balance piece is arranged on rotor and can effectively reduces compressor assembling height, obtain compact short structure, but equilibrium block is arranged on rotor can bring the large band of equilibrium block eccentric force to produce harmful effect to rotor structure, baroque frequency-changeable compressor rotor particularly, its structure is generally the magnet built-in structure, rotor core structure intensity is not strong especially, is subject to larger equilibrium block eccentric force and does the used time and likely sustain damage, and particularly rotor is every the magnetic bridge position.Therefore common its main equilibrium block of large capacity frequency-changeable compressor is arranged on live axle, and main equilibrium block is arranged on live axle and can brings assembly space not compact, the problem that requirement on machining accuracy is high.
