Abstract
The invention provides a multi-cylinder rotary compressor, which is not prone to refrigerant leakage from joints of separating plates which separate multiple compression chambers even when in the special running mode. The peripheries of dividing plates (130, 131) that constitute separating plates (114) for separating compression chambers are provided with cut portions. The separating plates are combined, and an arrow portion of a metal circular ring (135) is pressed to be deformed while the metal circular ring (135) is disposed on the outer peripheral surface of the separating plates. When the pressing operation is released, the circular arc space is formed between the inner peripheral surface of the metal circular ring (135) and the outer peripheral surface of the separating plates (114). A spring is disposed at a position where the metal circular ring (135) and the space are connected to absorb the interference so as to practically fix the dividing plates (130, 131).

Compression set 103 have also as the bent axle 108 of the running shaft of said motor 102, interior perimembranous be formed with clutch shaft bearing 109a the first framework 109, the first cylinder 110a, the first spring 111a, the first blade 112a, the first roller 113a, space bar 114, the second cylinder 110b, be formed with the second framework 116, the second spring 111b, the second blade 112b, the second roller 113b of the second bearing 116a in interior perimembranous, utilize short bolt 133 and long bolt 134 from fastening up and down.
Bent axle 108 has rotor embedding part 120, clutch shaft bearing insertion part 121, the first eccentric part 122a, intermediate portion 123, the second eccentric part 122b, the second bearing insertion part 125.The eccentric position of the first eccentric part 122a and the second eccentric part 122b differs 180 degree, rotates freely the first roller 113a and second roller 113b are installed at outer circumferential face separately.
Become the first pressing chamber 126a by the lower end surface of the first framework 109, the space that inner peripheral surface, the upper-end surface of space bar 114 and the outer circumferential face of the first roller 113a of the first cylinder 110a impale.
Equally, become the second pressing chamber 126b by the lower end surface of space bar 114, the space that inner peripheral surface, the upper-end surface of the second framework 116 and the outer circumferential face of second roller 113b of the second cylinder 110b impale.

Fig. 3 represents to form the stereogram of two fragmenting plates 130,131 of the isolated space bar 114 of the first pressing chamber 126a and the second pressing chamber 126b.
As shown in Figure 3, space bar 114 combinations have fragmenting plate 130 and fragmenting plate 131.Fragmenting plate 130 has upper-end surface 130a, lower end surface 130b, parting plane 130c and outer circumferential face 130d.Be useful on the groove 130e that inserts bent axle 108 at parting plane 130c.There are three place's otch at outer circumferential face 130d.
The second fragmenting plate 131 has upper-end surface 131a, lower end surface 131b, parting plane 131c and outer circumferential face 131d.Be useful on the groove 131e that inserts bent axle 108 at parting plane 131c.There are three place's otch at outer circumferential face 131d.At fragmenting plate 130 and fragmenting plate 131, be provided with through hole 130f and 131f that multiple (respectively having three in this example) are used for the bolton of assemble compressible device 103.
Fig. 4 is illustrated in the plan view of the isolated space bar 114 of the first pressing chamber 126a and the second pressing chamber 126b having been installed to the state of metal cirque 135.
Fragmenting plate 130 and fragmenting plate 131 are combined under the state of parting plane 130c and parting plane 131c contact, have a metal cirque 135 outer circumferential face 130d, 131d are chimeric.
By the chimeric setting magnitude of interference to space bar 114 and metal cirque 135, the pressing force in the parting plane effect of space bar 114 corresponding to magnitude of interference, prevents that fragmenting plate 130 and fragmenting plate 131 from staggering at joining portion.
In order above-mentioned " pressing force " to be described, to illustrate the method for the metal cirque 135 of pulling down Fig. 4.
Press metal cirque 135 from the direction of arrow everywhere of figure.The inner side of the metal cirque 135 of pressing part becomes circular-arc space.The length of the cut out portion that the circumferential Length Ratio of the inner peripheral surface of the metal cirque 135 joining with this space is faced is long.Therefore, when press everywhere arrow part time, the part that metal cirque 135 contacts with space bar 114, bloats to the radial outside of metal cirque 135.Like this, between the outer circumferential face of space bar 114 and the inner peripheral surface of metal cirque 135, form gap, can pull down metal cirque 135.
The installation of metal cirque 135 is by sequence contrary to the above, and in the time discharging the pressing of metal cirque 135, the part that the inner peripheral surface of metal cirque 135 and above-mentioned space are faced becomes spring and absorbs the magnitude of interference of metal cirque 135.
The groove 130e of fragmenting plate 130 faces mutually with the groove 131e of fragmenting plate 131, forms bent axle patchhole 132.
The diameter of bent axle patchhole 132 is slightly larger than the diameter of the intermediate portion of bent axle 108 123, less than the diameter of the first eccentric part 122a and the second eccentric part 122b.
Because be such structure, so even if the offset of eccentric part 122a, the 122b of bent axle 108 is large, also can reduce the diameter of bent axle patchhole 132, can reduce from the refrigeration agent of bent axle patchhole 132 and sew.
The rotary compressor 100 of present embodiment, by driving from 104 energisings of glass terminal the motor 102 that is arranged on housing 101 inside, rotates the bent axle 108 with the first eccentric part 122a and the second eccentric part 122b.
In addition, refrigeration agent is drawn into the first pressing chamber 126a and the second pressing chamber 126b via suction silencer 107 and suction pipe 106, along with the rotation of bent axle 108 is compressed, in the time reaching certain pressure, from exhaust port 136 discharged to housing 101 inside, and then by discharge tube 105 discharged to rotary compressor 100 outsides.
Fig. 5 represents the details of the bolt fastening structure of compression set 103.The first framework 109 and the first cylinder 110a, the second framework 116 and the second cylinder 110b are fixing by each three short bolts 133 respectively.In addition, the first framework 109 and the second cylinder 110b, the second framework 116 and the first cylinder 110a are fixing by each three long bolts 134 respectively, space bar 114 with the state clamped by the first cylinder 110a and the second cylinder 110b by jointly fastening.For this reason, act on axial fastening force and the frictional force of substantially horizontal at space bar 114.
In the time that rotary compressor 100 turns round, roller 113a, 113b slide on the plate face of space bar 114.Now, with respect to forming the fragmenting plate 130 of space bar 114 and power (power staggers) F1 that fragmenting plate 131 will stagger, the frictional force between cylinder 110a, 110b and space bar 114 and the pressing force sum being produced by metal cirque 135 become the endurance F2 that staggers.
Large by the endurance F2 ratio that makes the to stagger power F1 that staggers, space bar 114 can not stagger.The endurance F2 ratio that staggers while being generally designed to conventionally the turn round power F1 that staggers is fully large.
But, in the case of being called as the special operation mode of vacuum running, because the sliding variation between roller 113a, 113b and space bar 114, it is large that frictional force between roller 113a, 113b and space bar 114 becomes, frictional force between cylinder 110a, 110b and space bar 114 reduces simultaneously, so it is greatly difficult making to stagger endurance F2 than the power F1 that staggers.
Below, the compression set 103 when running occurs to vacuum is elaborated.
Vacuum running refers to, the special operation mode at the upstream side of the refrigerant flow path of compression set 103 because producing the rotary compressor 100 that turns round under certain former thereby inaccessible state.
Because want compressed refrigerant under the state that does not suck refrigeration agent, so the part, inside of compression set 103 approaches vacuum.For this reason, not cooled dose of the slide part of roller 113a, 113b and blade 112a, 112b is cooling, heated and the hot exapnsion of roller 113a, 113b, by space bar 114 and framework 109,116 are pressed to the axial of bent axle 108, the axial force of long bolt concentrates on the slip surface of roller 113a, 113b and space bar 114, and the frictional force between cylinder 110a, 110b and space bar 114 reduces.
By making the thickness of roller 113a, 113b and cylinder 110a, 110b with small difference, gap is set, thus the reduction of this frictional force can reduce vacuum running time.
But in the time that gap becomes large, the gap in the time conventionally turning round between roller 113a, 113b and cylinder 110a, 110b becomes large, becomes compression performance and reduces such balance relation.
In the case of producing such special operation mode, because mobile electric current increases in motor 102, so the running of the compressor 100 that can detection of excessive current stops the rotation.
During arrival shuts down, if space bar 114 does not stagger, remove the obturation of stream and restart.In this case, the performance of compression set 103 can not reduce.
But, during arrival shuts down, if the seam of space bar 114 staggers, between fragmenting plate 130 and fragmenting plate 131, form gap.In this case, restart rotary compressor 100 even if remove the obturation of stream, compression performance also can reduce.
By making metal cirque 135 chimeric with the periphery of space bar 114, improve the endurance that staggers.Therefore, chimeric for metal cirque 135, it is important controlling magnitude of interference.In the case of the periphery of space bar 114 or the size deviation in the interior week of metal cirque 135 large, the deviation of magnitude of interference also becomes greatly, the installation difficulty of metal cirque 135.
Therefore, in general, in order to maintain the dimensional accuracy between parts, the machining of cutting etc. is necessary.
But, in embodiments of the present invention 1, by otch being set in space bar 114 peripheries, carrying out machining without the inner peripheral surface of the outer circumferential face to space bar 114 or metal cirque 135, can reduce costs.
By in space bar 114 peripheries, otch being set, the part that forms space bar 114 and metal cirque 135 is chimeric, by making when mounted and the position distortion in opposite directions of the notch of metal cirque 135, can adjust magnitude of interference.Therefore, even in the case of the deviation of metal cirque self is large, also can easily assemble.In when batch production, even cheapnesss such as such as working pressure processing but the processing method of poor dimensional precision also can be manufactured space bar 114 or metal cirque 135.
In addition, also sheet material can be carried out to rolling and welding and is formed as toroidal, Zhou Jinhang expander in it is manufactured to metal cirque 135, comparablely manufacture more at an easy rate while utilizing cutting machine manufacturing.
In the time of the common running of compressor from needless to say, even just in case occur when special operation mode, the fragmenting plate 130,131 that forms space bar 114 also can not stagger mutually, can realize the small-sized and jumbo multi-cylindrical rotary compressor that while restarting, compression performance does not reduce.
In addition, before this situation in the periphery of fragmenting plate 130,131 with three place's otch is illustrated, but the quantity of otch is not limited to three places, for example also part at two places up and down in Fig. 4 only, can also be illustrated in figure 6 five places or more than it.
