Description
Technical field
The present invention relates to a kind of scroll compressor, relate in particular to structure and the manufacture method thereof of this scroll compressor.
Background technique
Since scroll compressor comes out, because it contains the plurality of advantages such as vibrations are little, noise is low, efficiency is high, part is few, therefore become the emphasis of international each large Compressor Manufacturing business develop actively.
The operation principles system of scroll compressor utilizes a motor running and drives a running shaft, makes a moving scrollwork with respect to the fixed scroll moving that revolves round the sun, and then makes successional generation volume ecto-entad enclosed space decrescence between two scrollworks.Thus, when the fluid of low-temp low-pressure enters after this enclosed space, via the process of extruding, can be transformed into the fluid of High Temperature High Pressure and be discharged by the central authorities of fixed scroll, thereby completing the process of gas compression.
Aspect the housing of scroll compressor, the shell constructions that adopt complete close formula in prior art, between the housing of each part, be to connect with welding manner, and the necessary assemblies such as motor and scrollwork assembly are just sealed in enclosure interior, are hedged off from the outer world more.Therefore although the cost that complete close sandwich type element structure is used is less, because its internal component cannot take out easily, if in the time of must keeping in repair or maintain for internal component, conventionally need very high expense, very uneconomical.
Therefore, just there is the shell construction of half close formula to be developed.Although half close sandwich type element structure is also comprised of a plurality of housings in prior art, and necessary assembly is also packaged in enclosure interior, but owing to conventionally paying do combination with screwed lock between a plurality of housings, therefore can be convenient to dismantling separation between housing, to carry out maintenance and the maintenance of internal component.
For example, yet because half close sandwich type element structure in prior art is formed with the housing of three or four formulas conventionally, therefore relative, each assembly of inside (motor, bearing support and fixed scroll) may be fixed on different frame sets.When carrying out assembly assembling, must first corresponding frame set and internal component be combined, then the assembly parts of each part is interosculated, be just accomplished the assembling of whole compressor.But this kind of structure and assembling method need to overturn each assembly parts repeatedly, not only waste time and energy, and more easily at assembling process, cause the damage of assembly.In addition, because each internal component system utilizes different housings assembly to carry out location, axle center, therefore often there is the situation of desaxe to occur.
In view of this, must provide a kind of scroll compressor of structure improvement, to improve shell construction and orientation type, and make its assembling mode more time saving and energy saving.
