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).

Fig. 2 is the drawing in side sectional elevation that cuts off the rotary compressor 100 of Fig. 1 with the A-A line.
In this mode of execution, use rotary compressor to describe as example with freezing air conditioner with two pressing chambers.
At upper body 101a, be provided be used for from the outside to the glass terminal 104 of motor 102 supply capabilities with make refrigerant compressed to the outside discharge tube 105 of discharging of compressor.
At middle casing 101b internal fixation motor 102 and compression set 103, the suction pipe 106 that imports refrigeration agents to compression set 103 connect middle casing 101b wall be fixed.
Motor 102 has stator 102a and rotor 102b, and rotor 102b is installed on the bent axle 108.The rotation torque that is produced by motor 102 is delivered to compression set 103 through bent axle 108.
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, at outer circumferential face separately the first roller 113a and the second roller 113b is installed with rotating freely.
The space that is impaled by the outer circumferential face of the upper-end surface of the inner peripheral surface of the lower end surface of first framework 109, the first cylinder 110a, space bar 114 and the first roller 113a becomes the first pressing chamber 126a.
Equally, the space that is impaled by the outer circumferential face of the upper-end surface of the inner peripheral surface of the lower end surface of space bar 114, the second cylinder 110b, second framework 116 and the second roller 113b becomes the second pressing chamber 126b.
As shown in Figure 2; On the first cylinder 110a and the second cylinder 110b, be installed in the first spring 111a and the second spring 111b of radial expansion, make the first blade 112a and the second blade 112b press to the outer circumferential face of the first roller 113a and the second roller 113b by the pressing force of each spring.The first blade 112a and the second blade 112b have the function that is divided into the first pressing chamber 126a and the second pressing chamber 126b low-pressure section 128 and high-pressure section 129.In addition, in this example, the position of the first blade 112a and the second blade 112b equates.
Fig. 3 is that expression constitutes two stereograms of cutting apart plate 130,131 with 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 the plate of cutting apart 130 and cut apart plate 131.Cut apart plate 130 and have 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.At outer circumferential face 130d three place's otch are arranged.
Second cuts apart 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.At outer circumferential face 131d three place's otch are arranged.Cut apart plate 130 and cutting apart plate 131, be provided with through hole 130f and 131f that bolton that a plurality of (respectively having three in this example) be used for assemble compressible device 103 is used.
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 the state of metal cirque 135.
Cut apart plate 130 and cut apart plate 131 and under parting plane 130c and parting plane 131c state of contact, be combined, a metal cirque 135 arranged in that outer circumferential face 130d, 131d are chimeric.
Through chimeric setting magnitude of interference,, prevent to cut apart plate 130 and cut apart plate 131 and stagger at the joining portion at the parting plane effect of space bar 114 pressing force corresponding to magnitude of interference to space bar 114 and metal cirque 135.
In order above-mentioned " pressing force " to be described, to be explained the method for the metal cirque 135 of pulling down Fig. 4.
Push metal cirque 135 from the direction of arrow everywhere of figure.The inboard of the metal cirque 135 of pressing part becomes circular-arc space.The length of the notch portion that the circumferential length specific surface of the inner peripheral surface of the metal cirque 135 that joins with this space is right is long.Therefore, when the arrow part of pushing everywhere, the part that metal cirque 135 contacts with space bar 114 bloats to the radial outside of metal cirque 135.Like this, between the inner peripheral surface of the outer circumferential face of space bar 114 and metal cirque 135, form the gap, can pull down metal cirque 135.
The installation of metal cirque 135 be by with above-mentioned opposite in sequence, when discharging the pushing 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 cutting apart plate 130 faces with the groove 131e of cutting apart plate 131 mutually, forms bent axle patchhole 132.
The diameter of bent axle patchhole 132 is bigger slightly than the diameter of the intermediate portion 123 of bent axle 108, and is littler than the diameter of the first eccentric part 122a and the second eccentric part 122b.
Because be such structure,, can reduce from the refrigeration agent of bent axle patchhole 132 and sew so, also can reduce the diameter of bent axle patchhole 132 even the offset of the eccentric part 122a of bent axle 108,122b is big.
The rotary compressor 100 of this mode of execution is through driving the motor 102 that is arranged on housing 101 inside from 104 energisings of glass terminal, make bent axle 108 rotations with the first eccentric part 122a and second eccentric part 122b.
In addition; Refrigeration agent is drawn into the first pressing chamber 126a and the second pressing chamber 126b via sucking silencing apparatus 107 and suction pipe 106; Along with the rotation of bent axle 108 is compressed; When reaching certain pressure, from exhaust port 136 rows to housing 101 inside, and then by discharge tube 105 rows to rotary compressor 100 outsides.
Fig. 5 representes the details of the bolt fastening structure of compression set 103.First framework 109 and the first cylinder 110a, second framework 116 and the second cylinder 110b are fixing by the bolt 133 of each three weak point respectively.In addition, first framework 109 and the second cylinder 110b, second framework 116 and the first cylinder 110a are fixing by each three long bolt 134 respectively, and space bar 114 is fastening jointly with the state quilt of being clamped by the first cylinder 110a and the second cylinder 110b.For this reason, act on the axial fastening force and the frictional force of substantially horizontal at space bar 114.
When rotary compressor 100 runnings, roller 113a, 113b slide on the plate face of space bar 114.At this moment, with respect to constituting cutting apart plate 130 and cutting apart power (power staggers) F1 that plate 131 will stagger of space bar 114, frictional force between cylinder 110a, 110b and the space bar 114 and the pressing force sum that is produced by metal cirque 135 become the endurance F2 that staggers.
Through making the endurance F2 ratio that the staggers power F1 that staggers big, space bar 114 can not stagger.The endurance F2 ratio that staggers when generally being designed to turn round the usually power F1 that staggers is fully big.
But; Under the situation of the special operation mode that is called as the vacuum running; Because the sliding variation between roller 113a, 113b and the space bar 114, the frictional force between roller 113a, 113b and the space bar 114 become big, the frictional force between cylinder 110a, 110b and the space bar 114 reduces simultaneously; So, make that to stagger endurance F2 than the power F1 that staggers be greatly difficult.
Below, the compression set 103 when running takes place to vacuum is elaborated.
Vacuum running is meant, the special operation mode that under the situation of running rotary compressor 100 under the upstream side of the refrigerant flow path of compression set 103 state former thereby inaccessible because of certain, produces.
Because do not want compressed refrigerant sucking under the state of refrigeration agent, so the part, inside of compression set 103 is near vacuum.For this reason; The slide part of roller 113a, 113b and blade 112a, 112b is not by refrigerant cools; Roller 113a, 113b are heated and hot exapnsion; Through pressing to space bar 114 and framework 109,116 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 the space bar 114 reduces.
Thickness through making roller 113a, 113b and cylinder 110a, 110b has small difference, and the gap is set, thereby can reduce the reduction of this frictional force in vacuum when running.
But when the gap became big, the gap when turning round usually between roller 113a, 113b and cylinder 110a, the 110b became big, became compression performance and reduced such balance relation.
Under the situation that produces so special operation mode, because the electric current that in motor 102, flows increases, so the running of compressor 100 but detection of excessive current is stopped the rotation.
Arrival shut down during, if space bar 114 do not stagger, then remove the obturation of stream and restart.In this case, the performance of compression set 103 can not reduce.
But, arrival shut down during, if the seam of space bar 114 staggers, then form the gap cutting apart plate 130 and cut apart between the plate 131.In this case, restart rotary compressor 100 even remove the obturation of stream, compression performance also can reduce.
Through making metal cirque 135 chimeric, improve the endurance that staggers with the periphery of space bar 114.Therefore, chimeric for metal cirque 135, the control magnitude of interference is important.Under the big situation of the size deviation in interior week of the periphery of space bar 114 or metal cirque 135, the deviation of magnitude of interference also becomes greatly, the difficult installation of metal cirque 135.
Therefore, in general, in order to keep the dimensional accuracy between parts, the machining of cutting etc. is necessary.
But, in mode of execution 1 of the present invention,, need not the outer circumferential face of space bar 114 or the inner peripheral surface of metal cirque 135 are carried out machining through otch being set in space bar 114 peripheries, can reduce cost.
Through otch being set in space bar 114 peripheries, form the local chimeric of space bar 114 and metal cirque 135, be out of shape through making the notch position in opposite directions with metal cirque 135 when mounted, can adjust magnitude of interference.Therefore, even under the big situation of the deviation of metal cirque self, also can easily assemble.When producing in batches, even cheapness such as working pressure processing but the processing method of poor dimensional precision also can be made space bar 114 or metal cirque 135 for example.
In addition, also can carry out rolling and welding to sheet material and form toroidal, Zhou Jinhang expander in it is made metal cirque 135, comparablely make more at an easy rate when utilizing the cutting machine manufacturing.
When the common running of compressor from needless to say; Even just in case when special operation mode takes place; Constitute cutting apart plate 130,131 and also can not staggering the small-sized and jumbo multi-cylindrical rotary compressor that compression performance does not reduce in the time of can realizing restarting each other of space bar 114.
In addition, before this situation that has three place's otch in the periphery of cutting apart plate 130,131 is illustrated, but the quantity of otch is not limited to three places, the also part at two places up and down in Fig. 4 only for example can also be illustrated in figure 6 as five places or more than it.
