Compression member 5 ' can comprise: cylinder, rotating piston and the blade for completely cutting off high low pressure chamber in the cylinder, and multiple for jointly limiting compression volume with described cylinder and supporting the bearing of bent axle 31 '.Bearing is usually located at the side of motor 3 ' to support bent axle 31 '.
As shown in Figure 1, in the rolling rotor type compressor of prior art, adopt bearing (upper bearing (metal) 4 ' and lower bearing 6 ') and bent axle 31 ' directly to contact the mode coordinated, and upper bearing (metal) 4 ' weld with can 2 '.Study discovery through inventor, the bearing of this structure of prior art is difficult to the requirement simultaneously meeting two aspects: on the one hand, and because bearing and bent axle form friction pair, be engaged characteristic both therefore requiring good, abrasion will meet relevant criterion; On the other hand, bearing meets the weld seam technological requirement with housing again.
In addition, inventor also finds that this structure of prior art has following drawback:
(1) upper bearing (metal) 4 ' is serious with the abrasion of bent axle 31 '.Specifically, micro-compressor is owing to limitting by size, and the height of upper bearing (metal) 4 ' is less than common rotary compressor.Bent axle 31 ' is thinner again, causes upper bearing (metal) 4 ' face to be pressed and increases, and local operating mode is comparatively severe, and abrasion are serious.In addition, to weld with can 2 ' improperly in situation at upper bearing (metal) 4 ', the axis of bent axle 31 ' may tilt, even if very little angle of inclination also may cause abrasion to concentrate between upper bearing (metal) 4 ' and bent axle 31 '.
(2) can 2 ' easily causes can 2 ' to be out of shape with upper cover 1 ', welding of lower cover 7 '.Specifically, because can 2 ' is generally cylinder-like structure, so when with upper cover 1 ', the welding of lower cover 7 ', be heated and easily deformation occur, thus, not only affect the overall tightness of compressor, and cause the rotor of motor and stator gap uneven, and then affect the overall coaxality of motor and bent axle, bearing, cylinder etc., reduce compressor operating efficiency and performance.
(3) gap between internal rotor 32 ' and external stator 33 ' is bad.Specifically, the rolling rotor type compressor of prior art, by the impact of component machining accuracy and rotor positioning datum, cannot eliminate the bad problem in rotor gap from root always.Due to upper bearing (metal) 4 ', to be mounted in can 2 ' interior, and the coaxality between the bearing surface of upper bearing (metal) 4 ' itself and the inwall of can 2 ' is difficult to ensure, the difficulty of processing of upper bearing (metal) 4 ' is high.External stator 33 ' is located based on can 2 '; Internal rotor 32 ' is located based on bent axle 31 ', bent axle 31 ' is located based on upper bearing (metal) 4 ' again, so when the coaxality between upper bearing (metal) 4 ' and can 2 ' is not up to standard time, gap between internal rotor 32 ' and external stator 33 ' will become very poor, even cause the wearing and tearing between internal rotor 32 ' and external stator 33 ', shorten motor working life, and a large amount of noise can be produced.

As shown in Figure 4, upper bearing (metal) 2 have band through hole 24 round plate 21, from the inner edge portion 25 of the inner circumferential projection of round plate 21 and the outer edge of going up downward-extension from round plate 21 outer rim respectively, outer edge comprises outer edge epimere 22 and outer edge hypomere 23, the middle cross section entirety of upper bearing (metal) 2 is in H-shaped, the outer circumferential face of the outer edge of upper bearing (metal) 2 as a part for housing, and is welded as a whole with the remaining part of housing.Also namely, in the present embodiment, housing primarily of upper bearing (metal) 2 outer edge, connect the outer edge epimere 22 of upper bearing (metal) 2 and the upper cover 1 of outer edge hypomere 23 and lower cover 7 forms respectively.
Visible, instead of multiple component such as central enclosure, upper bearing (metal) of prior art as unified frame with the upper bearing (metal) 2 of outer edge in the present embodiment, not only structure is simplified, and be conducive to improving the overall assembly precision of compressor, fundamentally solve puzzlement industry rotor clearance issues for many years.
Specifically, the outer edge epimere 22 of upper bearing (metal) 2 is provided with the first shoulder 221, and the outer edge hypomere 23 of upper bearing (metal) 2 is provided with the second shoulder 231, can by upper cover 1 laser bonding in the first shoulder 221, lower cover 7 laser bonding in the second shoulder 231, thus forms sealing shell.
The laser bonding used in the utility model embodiment utilizes the laser beam of high-energy-density as a kind of high-efficiency and precision welding method of thermal source.Use laser emission heated parts surface, surperficial heat is internally spread by heat transfer, adjusts, make work pieces meld, form specific molten bath parameters such as the width of laser pulse, energy, peak power and repetition frequencys.The most important thing is to drop to minimum requirement by entering heat, heat affected zone metallographic excursion is little, and the distortion caused because of heat transfer is also minimum.
As can be seen here, because upper bearing (metal) of the present utility model and housing are by laser bonding, make mounting position of motor (describe hereinafter) more flexibly like this, not only can not cause that the motor feels hot has a strong impact on performance, and making component spacing little, compressor arrangement is compacter.
About the means of fixation of motor, incorporated by reference to shown in Fig. 2 to Fig. 4, the external stator 33 of motor 3 is fixed on the inwall of the outer edge epimere 22 of upper bearing (metal) 2.The internal rotor 32 of motor 3 is set in the major axis portion 311 of bent axle 31, and internal rotor 32 is held tightly by colding pressing and is with dynamic crankshaft 31, but not as limit, internal rotor 32 also can pass through hot jacket, bonding and bent axle 31 to be fixed.Internal rotor 32 rotates relative to external stator 33, the rotating force of motor 3 is passed to cylinder 5, with compressed refrigerant.Like this, just do not need to be processed into the endoporus 91 of lining 9 coaxial further to the inner circumferential circle of the outer edge epimere 22 by upper bearing (metal) 2, can ensure the coaxial and good gap of internal rotor 32 and external stator 33 yet.Except above-mentioned means of fixation, the external stator 33 of motor 3 also directly can be fixed at the inner circumferential circle upper (such as, arranging the 3rd shoulder in inner circumferential, not shown) of the outer edge epimere 22 of upper bearing (metal) 2.Like this, because the inner circumferential circle of outer edge epimere 22 is as the positioning datum of external stator 33, the endoporus 91 of lining 9 is as the positioning datum of internal rotor 32, need by processing further the outer edge of bearing, make the inner circumferential of the outer edge epimere 22 of upper bearing (metal) 2 circle coaxial with the endoporus 91 of lining 9, thus can ensure that internal rotor 32 is coaxial with external stator 33, reach splendid Spielpassung effect between the two, reduce abrasion and noise.
Also be provided with passage 26 in upper bearing (metal) 2, one end UNICOM liquid-storage container of passage 26, cylinder 5 described in the other end UNICOM, flow into from liquid-storage container 8 in cylinder 5 for coolant, this structure can not produce air-breathing internal leakage, can improve compressor performance.
