Description
Technical Field
The invention relates to the field of compressors, in particular to a damping mechanism of a compressor.
Background
For the fully-closed refrigerator refrigerating compressor, the lower the vibration design of the whole machine is, the better the vibration design is, the more difficult the vibration is reduced on the existing structure, and meanwhile, the phenomenon of resonance is easy to occur in some frequency bands because the rotating speed of the variable-frequency compressor can change. Because the refrigerator compressor industry competes very strongly, the improvement of performance or the maintenance of performance (i.e. the reduction of vibration or the maintenance of vibration at the original level) is a pursuit of the reduction of raw material consumption and the improvement of production efficiency.
In the conventional structure, as shown in fig. 1, in a refrigerator compressor, a movement 1 may generate up and down vibration, torque vibration, and various irregular wobbles due to its own operational characteristics. Various vibrations of the movement 1 are transmitted to the cylindrical spring 5 through the stator bolt gasket 2, the stator bolt 3 and the upper bushing 4, and after being damped by the cylindrical spring 5 (mainly, the vibration damping function in the up-down direction), the vibrations are transmitted to the whole machine through the lower bushing 6 and the steel nail 7, so that noise is generated, and resonance and noise generated due to resonance are generated. The traditional structure has the advantages that the connecting parts of the vibration transmission paths are more, the parts are more, the generated machining accumulated error is large, the phenomenon of connecting dislocation is generated, vibration and noise are increased, the vibration and noise are unfavorable, meanwhile, the connecting parts are more (one vibration transmission path consists of 6 parts, each machine core is provided with 4 identical transmission paths, namely 4x6 = 24 parts), the material cost is high, the stock cost is increased, the assembly process is more, the labor cost is high, and the manufacturing efficiency is low. The traditional vibration reduction is a cylindrical spring, mainly reduces the up and down vibration of the movement 1, has little effect in other directions, has fixed rigidity, changes the transmission speed of the variable frequency compressor in the working process, is very unfavorable for avoiding resonance, and has a resonance phenomenon easily generated in some frequencies. Meanwhile, the traditional cylindrical spring 5 has no spring-off prevention function, and the movement can have a spring-off phenomenon (the spring can be released from the connecting structure) in the complex road condition transportation process.
