Thus, even balace weight 54 is lightened, also can eliminate the vibration that the eccentric motion along with pin portion 19 produces effectively by the relation of torque.In addition, owing on the periphery of bearing portion 6 position of centre of gravity is arranged, so the bending of running shaft 5 also is reduced, and can suppress the problem of crank portion 41 and bearing portion 6 OFFSET COLLISION.In addition because balace weight 54 is fixed on the running shaft 5 of support frame 4 one sides by rotor 39, even thereby be expanded to the periphery of bearing portion 6, also can keep enough installation strength.
Then, 61 expulsion valves that are mounted on fixed scroll 7 end plates 11 another sides (with the uper side surface of cover plate 13 opposite sides).This expulsion valve 61 roughly is the support body 63 of a shape by the section of installing on the bolt 62,62 corresponding with the tap hole 14 of end plate 11, but and the side of this support body 63 and below the open easy on and off that forms remain on disc-shaped valve body 66 formations mobile space 64 in movably.The center of this valve body 66 is consistent with the center of tap hole 14.And, on the mobile space portion 64 of support body 63, constitute surface of contact 67.
In addition, form the 1st and the 2nd communication paths 68,69 of two perforations on the upper wall of support body 63, the lower ending opening of each communication paths 68,69 is on surface of contact 67, and upper end open is in hyperbaric chamber 9.Two communication paths 68,69 are extended in vertical direction, and simultaneously, the 1st communication paths 68 is opened on the surface of contact 67 with the corresponding part of leaving from valve body 66 centers in position.On the other hand, the 2nd communication paths 69 is positioned at and the corresponding position of end cap 1B central lower, and has been formed centrally through hole 71 in end cap 1B.And, on the 2nd communication paths 69, being inserted with pipe 72 as the part of temperature-detecting device not shown in the figures, this pipe 72 is drawn out to the outside by through hole 71.The temperature-sensitive portion of temperature-detecting device is housed in this pipe 72.
Below, the assembling sequence of scroll compressor S of the present invention is described.At first, running shaft 5 is entrenched on the rotor 39 of electric element 3, with each balace weight 54,56 by being pressed into or hot pressing is chimeric is assembled on the running shaft 5.And the stator 38 of mounting electric element 3 on supplementary bearing 42 makes through hole 44 consistent with bolt hole 43.Then, the rotor 39 that is assembled with running shaft 5 and balace weight 54,56 is inserted in the stator 38, allows the lower support of running shaft 5 on supplementary bearing 42.Then, support frame 4 is covered on stator 38, make bolt hole 46 consistent, simultaneously, allow crank portion 41 insertions of running shaft 5 be supported in the bearing portion 6 with through hole 44.And, aforesaid bolt 47 is inserted by the order of bolt hole 43, through hole 44, bolt hole 46 from supplementary bearing 42 1 sides, finally be screwed on the bolt hole 46, thereby support frame 4, electric element 3 and supplementary bearing 42 are assembled in advance, form one.Here it is state shown in Figure 9.By assembling,, balace weight 54 expansions assemble even also can having no obstacle ground according to this order.
In addition, with above-mentioned reversed in order, also the crank portion 41 of running shaft 5 with rotor 39 of running shaft 5 and balace weight 54,56 can be supported in the bearing portion 6 of support frame 4 at first, then, rotor 39 is inserted in the stator 38, afterwards, allow lower end (the other end) side of running shaft 5 be supported on the supplementary bearing 42.Also can have no obstacle ground assembling balace weight 54 with this order.
On the one hand,,, cover thereon, allow cover plate 13 and 16 mesh cover plate 16 swing scrollwork 8 down to allow cover plate 13 mode mounting up with fixed scroll 7.Then, with Oldham's coupling 20, allow key 21,21 as the downside mounting on swing scrollwork 8, allow and match in key 21,21 and the keyway 23,23 of swinging scrollwork 8.Then, staggering on the fixed scroll 7 of 90 degree positions with the bolt key member 24,24 of screwing on admittedly, under the state that is projected into upside than Oldham's coupling 20 with in each keyway 22,22, match with this key 21,21 and keyway 23,23.So just, assembled vortex compressing member 2 shown in Figure 7.
Then, support frame 4, electric element 3 and the supplementary bearing 42 that goes out as shown in Figure 9 assembled in advance, cover the main body 1A of seal container 1 thereon from top, integral body is inserted among the main body 1A, supplementary bearing 42 is pressed on the internal surface that is fixed to main body 1A.Then, aforesaid support locating stud 31,31 is inserted in the pin-and- hole 32,32 of support frame 4.Then, with the Oldham's coupling 20 of as shown in Figure 7 the vortex compressing member 2 that assembles in advance as below cover main body 1A, locating stud 31,31 is inserted in the pin-and- hole 34,34 of fixed scroll 7, allow bolt hole 33 ... bolt hole 29 with support frame 4 ... consistent, the pin portion 19 of running shaft 5 is coupled in the axle sleeve hole portion 17 of swing scrollwork 8, is assembled on the running shaft 5 thereby will swing scrollwork 8.
And, aforesaid bolt 36 is inserted into bolt hole 33 from fixed scroll 7 one sides ... in, with the bolt hole 29 of support frame 4 ... be screwed in together, but the temporary fixed state in the bolt hole 29 that at this moment allows bolt 36 be in not tighten to support frame 4.
Under this state, then carry out the adjustment in gap between the cover plate 13,16 of each scrollwork 7,8.Figure 10 is the structural drawing of expression regulating device 90.For example pump 91, high pressure regulator 93, low-pressure regulator 94, switching valve 96, connector 97 and the formations such as pipe 92 that connect them that this regulating device 90 is used by pressure fluids such as generating pressurized air or nitrogen.
And, at first with being arranged on the stationary platen shown in Figure 10 98 of the state of aforesaid temporary fixed fixed scroll 7, the main body 1A of seal container 1 is fixed.And, connector 97 is connected on the exhaust port 14 of fixed scroll 7, allow pump 91 move.And, allow the pressure fluid such as pressurized air, nitrogen of adjusting to certain pressure P1 by high pressure regulator 93 by switching valve 96 flow in the pressing chamber 18 from exhaust port 14 through connector 97.
By the pressure of this fluid, the opposite rotation of sense of rotation of the beginning of swing scrollwork 8 and common refrigerant gas when the compressed refrigerant compression operation.And, even under temporary fixed fixed scroll 7 is not assembled in regular locational situation when temporary fixed, rotation by swing scrollwork 8, the cover plate 16 of swing scrollwork 8 also can be pushed back the cover plate 13 of the fixed scroll 7 assembling oil by coating, fixed scroll 7 fall back on the whole periphery of cover plate 13 not with cover plate 16 contacted positions on.Under this state, tight a bolt 36 equably, thereby fixed scroll 7 is fixed on the optimal position of support frame 4.
At this moment, determine that locating stud 31 that the position of fixed scroll 7 is used and the gap between each pin-and- hole 32,34 are owing to be set in the scope of foregoing 30 μ m～70 μ m, so the scope that pushes back the cover plate 13 of fixed scroll 7 by this counterrotating is limited on the gap between this locating stud 31 and the pin-and- hole 32,34, in the method for above-mentioned definite rotational position in the past, in for example gap is under the situation of 0～100 μ m, allowing the gap be under the above-mentioned 30 μ m situations is 35 μ m～65 μ m, is in the scope of 15 μ m～85 μ m under above-mentioned 70 μ m situations.
Thus, even locating stud 31 does not have strict regulations with the precision of pin-and- hole 32,34, make gap between the cover plate 13,16 can be on whole periphery than in the past (0～200 μ m, perhaps, 0～200 μ m) little, and, can make it homogenization, thereby realize the remarkable improvement of scroll compressor S performance and the reduction of noise in operating.
After the predetermined screwing force of this fixed scroll 7 and support frame 4 usefulness bolts 36 is fixing, certain pressure P 2 reduced pressure by employing switching valve 96, low-pressure regulator 94 (with the reduce pressure mechanism of certain pressure of pressure fluid) to allow the pressure of the pressure fluid that injects from exhaust port 14.
At this moment, be fixed on the unsuitable position under the situation of support frame 4 at fixed scroll 7, the approaching mutually or contact of the sidewall between the cover plate 13,16 of each scrollwork 7,8, thus slip resistance is increased, allow the rotation of swing scrollwork 8 stop.In addition, under the coaxial situation of the bearing portion 6 that can not get support frame 4 and supplementary bearing 42, slip resistance also can become greatly, thus the rotation of the scrollwork 8 that stops swinging.
Therefore, pressure P 2 is decided by admissible slip resistance, whether good can the sensors by adopt detecting sound, rotational speed etc. etc. (can measure rotation status mechanism) come wobble detection scrollwork 8 and crank portion 41 continue the situations of rotation by pressure P 2, measure assembly precision thus.Thus, do not need to adopt such in the past high price torque meter, just can detect fixed scroll 7 and whether be fixed on the correction position of support frame 4.
Like this, after having detected fastening between fixed scroll 7 and the support frame 4, connector 97 is taken off from fixed scroll 7, make expulsion valve 61 corresponding with the tap hole 14 of the end plate 11 of fixed scroll 7, be fixed on the end plate 11 by bolt 62,62, be inserted into the communication paths 69 from top pipe 72.This state is exactly a state shown in Figure 3.
Then, end cap 1B hot pressing is fixed to around the end plate 11 of fixed scroll 7, covers main body 1A by the high low pressure sealing, at this moment, allow upright pipe 72 be inserted in the through hole 71 of end cap 1B at first as shown in Figure 3,, cover main body 1A allowing end cap 1B hot pressing be fitted on the end plate 11 under this state.At this moment, aforesaid communication paths 69 is owing to be positioned at and corresponding position, end cap 1B center, so by making pipe 72 also corresponding with the center of end cap 1B, allow end cap 1B cover main body 1A under the state in being inserted into through hole 71, carry out location and the assembling of end cap 1B thus with respect to main body 1A easily.The restriction of sense of rotation is also relaxed during in addition, to hot pressing.
Like this, allow hot pressing around the end plate 11 of fixed scroll 7 be fixed to the internal surface of end cap 1B, after allowing end cap 1B cover main body 1A, welding around the end cap 1B is fixed on the main body 1A.Afterwards, bottom 1C is covered in the lower end of main body 1A, welding around it is fixing.And, other pipe is installed in the assembling of just having finished scroll compressor S on the seal container 1.Under this state, from top in order that vortex compressing member 2, support frame 4, electric element 3 and supplementary bearing 42 is integrated, 2 at the place of being pressed into of chimeric place of hot pressing and supplementary bearing 42 remains on the seal container 1 around the end plate 11 of fixed scroll 7.
Below, the action of scroll compressor S of the present invention is described.If by power supply from terminal T, rotor 39 rotations of electric element 3, then this rotating force will be sent on the swing scrollwork 8 by running shaft 5.
That is, swing scrollwork 8 is revolved round the sun on circular track under the state with respect to fixed scroll 7 not rotations by Oldham's coupling 20 by driving with respect to these running shaft 5 eccentric axle sleeve hole portions that insert 17 in the pin portion 19 of running shaft 5.And, the compression volume 18 that fixed scroll 7 and swing scrollwork 8 will be formed between their cover plate 13,16 dwindles towards the inboard successively from the outside, the low pressure chamber 10 of compression in suction pipe 51 flow into seal container 1, by electric element 3, flow to the notch 27 of support frame 4 ... refrigerant gas.
This refrigeration agent that has compressed is discharged in the hyperbaric chamber 9 from the tap hole 14 of fixed scroll 7, and the valve body 66 of expulsion valve 61 is lifted by the high-pressure refrigerant of discharging from downside tap hole 14, leaves from tap hole 14, opens this tap hole 14, simultaneously, be close on the surface of contact 67.The refrigeration agent of discharging from tap hole 14 enters in the hyperbaric chamber 9 from the lateral opening of mobile space portion 64, is discharged to outside the seal container 1 from discharge tube 52.
On the one hand, if electric element 3 stops, and the rotation of rotor 39 stops, then stopping owing to aforesaid compression, and therefore in order to allow pressure balance, can adverse current just lead to the gas of tap hole 14.And owing to have communication paths 68 on surface of contact 67, be connected with hyperbaric chamber 9, thereby the pressure in this hyperbaric chamber 9 will draw back valve body 66 as back pressure from surface of contact 67, fall the below and close tap hole 14.At this moment, communication paths 68 is owing to surface of contact 67 upper sheds in the central position that is positioned at the valve body 66 that staggers, so valve body 66 is in from the state of the position separating of close its edge part.Thus, seal rapidly by 66 pairs of tap holes 14 of valve body.
In addition, the temperature-sensitive portion of temperature-detecting device being housed in this pipe 72, is under the situation of the abnormal high temperature be scheduled in this detected discharge temperature of temperature-sensitive portion (refrigerant temperature of discharge), and control gear not shown in the figures stops the protection action of electric element 3.At this moment, temperature-detecting device can detect after tap hole 14, thereby the correct discharge temperature of perception scroll compressor S can suitably be avoided because abnormal high temperature and scroll compressor S is produced the problem of damage.
In addition, among the embodiment, though be with the 90 degree positions of staggering the state that arm 28 is installed to be set to be formed with 4 places on support frame 4, but notch 27 is formed 3 places (the 120 degree positions of staggering), thereby forming 3 places installation arm 28 also is fine, perhaps, arm 28 will be installed also is fine more than forming 5 places.But under any circumstance, above-mentioned terminal T and key member 24 all are to be configured in the notch 27 in not corresponding to mode.
