Description
The invention relates to hermetic type compressor and the inner invention that is pressed into the closed shell manufacture method that is equipped with compressor arrangement portion and motor component such as rotor-type compressor.
The rotor-type compressor of using in the cooling recirculation system such as the kind equipment of air conditioner, refrigerator is the closed-type compressor that is equipped with compressor arrangement portion and motor component in closed shell.
Above-mentioned closed shell is formed by housing and two parts of lid at least.Above-mentioned housing has the cylinder-like part of the end or both ends open to form by an end, and its opening end is closed by above-mentioned lid.
Above-mentioned housing inner circle wall face place is pressed into or hot pressing is equipped with the critical piece cylinder barrel of formation compressor arrangement portion and the stator of motor component.
Because said structure, with respect to the closed shell fitted position precision of housing particularly, be higher requirement such as circularity, cylindricity as the compressor arrangement portion of inside components and motor component.
So, in above-mentioned housing molding technology, adopted high-precision technological method, plasticity method expander just, promptly so-called expansion method.
This method as shown in Figure 7.At first as Fig. 7 (A), forming the expansion action piece S that inserts the some of cutting apart on the housing inner circle wall face M cylindraceous and be called expansion.Like this, the bi-side that are fan-shaped each expansion member S contact with each other, and section integral body is circular.
Then, insert coniform expanding body (not shown) in expansion by force with the bi-side of action piece S, each expansion is radially opened with action piece S court, its periphery arc surface and the M crimping of housing inner circle wall face and work are in order to expansionary force.
Housing inner circle wall face M is at above-mentioned expansionary force effect lower edge radial expansion distortion, the amount of deformation X that it is actual
bApproximately being several ten microns～hundreds of microns, is the size of amplifying shown in the figure.
Because each expansion is fan-shaped with action piece S section, so during expansion, respectively bi-side of expanding with action piece S have formed the gap each other.Because the relative housing parts in this gap is provided with and is subjected to radial expansion force, also just form the residual portion that deforms that is provided with.
Above-mentioned this residual fraction is called segmentation trace K (also being expansion trace, expansion segmentation etc.) again.
Shown in Fig. 7 (B), the diameter that is formed by above-mentioned segmentation trace K is the inscribed circle that the circle of A1 has become housing.Though can make expansion consistent with the final external diameter of housing with action piece S outer circumference diameter when design, the expansion amount when the elastic return amount of the size of above-mentioned inscribed circle diameter and case material, expander has substantial connection, otherwise is difficult to obtain desired diameter. B1 is the swollen distortion rear case inner circle wall face M place diameter of a circle that rises among the figure.
During the hermetic type compressor operation that forms with said method, cause by above-mentioned compressor structural portion compression transmission.The electric and magnetic oscillation that vibration and above-mentioned motor component cause is incited somebody to action radiation noise towards periphery after housing transmits.
Because above-mentioned compressor arrangement portion and motor component will be combined closely by above-mentioned each segmentation trace place and housing, so its supporting structure instability.Further, such as concerning motor component, its outer circumferential face has formed the path of cooled gas, is provided with some notch parts that form owing to silicon steel sheet extrusion-deformation simultaneously.
Above-mentioned segmentation trace is positioned on the notch part relevant position sometimes because of assembly error, also can be positioned at sometimes on the notch part motor component outer circumferential face in addition.So just make vibration transfer unstable and complicated, the consequent case noise width of cloth penetrates direction and frequency also can be disperseed very much, causes noise very big.
In addition, the compressor arrangement portion that gets as the precise part assembling, in order to prevent assembly deflections, closely setting-in is gone in the housing.But because the existence of above-mentioned segmentation trace, the precise part that contacts with this position will produce local deformation.These all are the conditions that forms noise, so demand proposing to reduce the countermeasure of noise urgently.
On the other hand, assemble under the situation of the grease of denier, then when the cool cycles operation of reality, can have a strong impact on compression efficiency in the cooled gas because of grease is dissolved in if relevant component are stained with.So traditional way is compressor arrangement portion and motor component to be packed into will carry out degreasing behind the housing, in order to clean enclosure interior, remove grease, washing agent is the Methyltestosterone that coil covering in the motor component is not produced corrosive action.
Above-mentioned cleaning is to carry out after assembling, that is to say it is the assembling of carrying out motor component etc. under the residual state that grease arranged on the housing inner peripheral surface.Like this, even be formed with the segmentation trace on the housing, because the grease before removing has lubrication, scratch and so on problem can not take place and influence manufacturability.
But,, determined to stop using the policy of Methyltestosterone because the consciousness of the environment of preserving our planet in recent years becomes more and more stronger comprehensively.The substitute is water-soluble washing agent, but because of its corrosive action to the insulating motor coil layer, so must before motor component is packed housing into, clean the housing endosome.
Like this, just motor component etc. must be pressed in the housing of complete degreasing, then above-mentioned segmentation trace will become the starting point that scratch takes place.This kind scratch not only can produce and press-fit manufacturability issues such as bad, and can rest on because of the fragment that scratch forms and influenced reliability in the compressor arrangement.
In view of the above problems, the objective of the invention is to, provide the manufacture method of a kind of hermetic type compressor with following characteristics closed shell relevant: use a kind of expansion action piece that does not produce abrasive segmentation trace that on housing inner circle wall face, forms with this hermetic type compressor, even and the noise that the vibration that produces of compressor arrangement portion or motor component passes to its generation of closed shell also can reduce, simultaneously, assembling the time can prevent from really to abrade with local deformation to realize high-precision assembling and higher reliability.

Because the straight A of inscribed circle is the same substantially with housing 2 internal diameter B, and slightly big, so stator 9 is pressed in it being in state of contact one with housing inner circle wall face 2a than inscribed circle diameter A due to 9 external diameter.In addition, the above-mentioned cylinder barrel seat 12 of formation compressor arrangement portion 8 also is to be pushed down into housing inner circle wall face 2a's with above-mentioned same state.
As shown in Figure 3, on the outer circumferential face of said stator 9, uniformly-spaced be formed with the 4 plat part 9a of place.And above-mentioned expansion divided 8 fens with action piece 21 grades, was formed with 8 place's segmentation traces 21, so make above-mentioned plat part 9a aim at one of them segmentation trace 21 respectively when being pressed into.
Because the above-mentioned portion 21 of passing through mutually highlights in the inscribed circle outside, so and formed the space portion of enough capacity between the above-mentioned plat part 9a, can guarantee as cooled gas path.
As shown in the figure, when expansion with action piece 20 when expanding to greatest extent, it can produce the gap each other.Though the front had been narrated above-mentioned segmentation trace 21 and had been highlighted in the inscribed circle outside, but in fact, in segmentation trace apex office since above-mentioned expansion produce the gap each other with action piece and be not close together, so the words of this place, summit expansion can be formed the recess of certain radius of curvature well, perhaps be even shape, be summit place at least and be provided with outstanding.
When at this hermetic type compressor of cool cycles driving in service, motor component 7 will be because electric and magnetic oscillation and the surge pressure that reaches silicon steel sheet and so on will produce vibration, but because its outer circumferential face and housing inner circle wall face 2a are in and contact condition, so even above-mentioned vibration is delivered on the closed shell 1 by the connecting part with housing 2, this kind vibration transfer is stable, and noise direction that is produced and frequency can great changes yet.
In addition, because segmentation trace 21 is with compressor arrangement portion 8 and motor component 7 and be provided with very big contact force, institute in the housing 2 during assembling, can not abrade in the past, did not also have local deformation simultaneously, can keep the precision of relevant parts.
Fig. 6 has represented the measured result of hermetic type compressor noise level that produces when driving of hermetic type compressor of the present invention and conventional construction respectively.
Shown in Fig. 6 (B), for hermetic type compressor with conventional construction, the peak change of the noise level that each operation frequency is relative rises and falls very big, and for the hermetic type compressor of the present invention shown in Fig. 6 (A), the relative noise level peak change of each operation frequency is littler than the conventional construction, obviously, structure of the present invention has reduced noise.
In above-mentioned form of implementation, above-mentioned expansion with the circular arc external diameter of action piece 20 with greater than inscribed circle diameter φ A for imposing a condition, can not limit so yet.Circular arc can be arranged to have if the circular arc of different curvature radius is gathered and its segmentation trace 21 is not contacted with housing 2 inscribed circles, so also can obtain above-mentioned same effect.
