Then, as shown in Figure 10 and Figure 11, with last discharge cover 11 for example by the peripheral part that is installed in upper bearing (metal) 9 such as being pressed into, discharge cover 11, upper bearing (metal) 9, casing top half 5, intermediate clapboard 4 and following cylinder 6 in order to link, upside in-and-out bolt 15 is inserted the logical bore portion 5b that are arranged on the casing top half, and binding is fixed on the screw section 6a last (S70 of Figure 15) that is arranged at down on the cylinder.Each three upside in-and-out bolt 15 and downside in-and-out bolt 16 alternately are arranged on the Zhou Fangxiang as the sense of rotation of bent axle 3.Being preferably in same circumference equal intervals ground is provided with.But also with its approximate setting.
Afterwards, the lower bearing binder bolt 14 that temporarily will link time cylinder 6 and lower bearing 10 is pulled down.This is in order to cover 12 with lower bearing binder bolt 14 fixing discharges down.As Figure 12 and shown in Figure 13, temporarily lower bearing binder bolt 14 is pulled down, for example wait discharge down cover 12 for the peripheral part that is installed in lower bearing 10 by being pressed into, and once more with lower bearing binder bolt 14 link discharge down cover 12, lower bearing 10 and following cylinder 6 (S80 of Figure 15).
As mentioned above, upside in-and-out bolt 15 and the downside in-and-out bolt 16 of compression mechanical part 30 by equal number (in the present embodiment being 3) respectively alternately is attached on the same circumference as the sense of rotation of bent axle 3 equally spacedly, power acts on respectively on the thrust face of each parts uniformly thus, therefore, with existing in order to link casing top half 5, following cylinder 6 and intermediate clapboard 4, and in the outside of upper bearing (metal) 9 and lower bearing 10, utilize special-purpose bolt to link the mode of casing top half 5 and intermediate clapboard 4 and following cylinder 6 and intermediate clapboard 4 respectively, link upper bearing (metal) 9 and casing top half 5 and lower bearing 10 and following cylinder 6 respectively, only from descending cylinder 6 sides the mode that these parts and intermediate clapboard 4 are attached on the screw section 5a that is arranged on the casing top half is compared with downside in-and-out bolt 16, reduce the casing top half 5 and the plane lapping portion of following cylinder 6 or the distorted deformation of internal diameter grind section that when linking, produce, therefore can obtain the assembly precision height, leakage loss or slip loss are low, high efficiency compressor.In addition, upside in-and-out bolt 15 and downside in-and-out bolt 16 alternately are provided with on as the Zhou Fangxiang of the sense of rotation of bent axle 3 and get final product.The radical of upside in-and-out bolt 15 and downside in-and-out bolt 16 is at least each two and gets final product.
And, by dwindling the upside in-and-out bolt 15 that links compression mechanical part 30, the circumference spacing between the downside in-and-out bolt 16, can straitly set the plane lapping portion of casing top half 5 and following cylinder 6, can make intermediate clapboard 4 miniaturizations, therefore, can the be reduced twin-tub rotation-type hermetic type compressor 1000 of low price of material cost and processing charges.
Second mode of execution
Figure 16 is the figure of expression second mode of execution, is the longitudinal section of twin-tub rotation-type hermetic type compressor 2000.
As shown in figure 16, in the twin-tub rotation-type hermetic type compressor 2000 of present embodiment, suck connecting pipe 19 and casing top half 5 or the suction port binding of cylinder 6 down with one from storage 18.The example of Figure 16 is that the suction port that sucks connecting pipe 19 and casing top half 5 links.
The assembling sequence of compression mechanical part 30 is identical with first mode of execution.When assembling twin-tub rotation-type hermetic type compressor 2000, compression mechanical part 30 and electric element 2 are inserted seal container 1 inside, then, the suction port with outer tube 20 insertion casing top halfs 5 is pressed into its inside with interior pipe 21.Afterwards, will insert outer tubes 20 from the suction connecting pipe 19 of storage 18 and weld.The suction port of following cylinder 6 is communicated with suction connecting pipe 19 by air inlet connect apertures 40.
Since the heating in the time will inserting outer tube 20 from the suction connecting pipe 19 of storage 18 and weld, possible distorted deformation such as the internal diameter grind section of casing top half 5 and following cylinder 6 or plane lapping portion, and leadkage loss or slippage loss change are big, compression horsepower reduces.
And, on casing top half 5 and following cylinder 6, all has the twin-tub rotation-type hermetic type compressor 1000 (first mode of execution) that sucks connecting pipe, because the pressure pulsation that respectively sucks the refrigerant among connecting pipe 19a, the suction connecting pipe 19b during compressor operation increases, therefore, might cause compression horsepower to reduce.
And, if 21 o'clock bump of pipe surpasses the shearing force of each bolt of fixing compressor structure portion 30 in being pressed into, then the concentricity of the internal diameter of the internal diameter of upper bearing (metal) 9 and lower bearing 10 might depart from, the reliability reduction.
Therefore, in the twin-tub rotation-type hermetic type compressor 2000 with a suction connecting pipe 19 shown in Figure 16, compare with twin-tub rotation-type hermetic type compressors with two suction connecting pipes 19, because it is a place that the suction connecting pipe 19 from storage 18 is carried out the welding part, therefore reduced heat input quantity to compression mechanical part 30, the distorted deformation of the internal diameter grind section of casing top half 5 and following cylinder 6 or plane lapping portion etc. dwindles, leakage loss or slip loss reduce, and therefore can obtain high-power twin-tub rotation-type hermetic type compressor 2000.
And, in twin-tub rotation-type hermetic type compressor 2000 with a suction connecting pipe, because the stream of refrigerant is at the fork in front of each cylinder suction port of casing top half 5 and following cylinder 6, therefore, compare with twin-tub rotation-type hermetic type compressors 1000 with two suction connecting pipes, the pressure loss reduces, and can further realize high power.
And, in twin-tub rotation-type hermetic type compressor 2000 with a suction connecting pipe, because pipe 21 a place is pressed in, so reduced the influence that the concentricity to the internal diameter of the internal diameter of upper bearing (metal) 9 and lower bearing 10 causes that is pressed into, can further improve reliability because of interior pipe 21.
And, in twin-tub rotation-type hermetic type compressor 2000 with a suction connecting pipe, compare with having two twin-tub rotation-type hermetic type compressors 1000 that suck connecting pipe, number of spare parts is less, therefore can obtain the twin-tub rotation-type hermetic type compressor 2000 of low price.
The 3rd mode of execution
Figure 17, Figure 18 are the figure of the 3rd mode of execution, are the sectional views of the major component of compression mechanical part 30.
Shown in first mode of execution and second mode of execution, owing to link compression mechanical part 30 by each bolt, so distorted deformation takes place for the internal diameter grind section of casing top half 5 and following cylinder 6 or plane lapping portion, cause the circularity reduction thus, so leadkage loss or slippage loss might improve.
Therefore, in order to reduce the distorted deformation of internal diameter grind section, release portion (escaping Ga portion) is set on the end face of screw section 5a and screw section 6a, described screw section 5a is arranged on the casing top half of the twin-tub rotation-type hermetic type compressor shown in first mode of execution and second mode of execution, and described screw section 6a is arranged on down on the cylinder.
As shown in figure 17, in case utilize upper bearing (metal) binder bolt 13 that casing top half 5 and upper bearing (metal) 9 are fixed by the screw section 5a that is arranged on the casing top half, then the internal diameter grind section of casing top half 5 is with ground shown in dotted line distorted deformation.
Therefore, as shown in figure 18, by at the 5c of release portion on the end face that columnar, the screw section that is arranged on casing top half with certain depth is set on each plane lapping portion side of the screw section 5a that is arranged at casing top half be arranged on the 5d of release portion on the end face of screw section of casing top half, the distorted deformation of the internal diameter grind section in the time of can suppressing bolt and link.
Thus, the circularity of the internal diameter grind section of the cylinder that produces in the time of can improving by each bolt binding compression mechanical part 30 can obtain the low high power compressor of assembly precision height, leadkage loss or slippage loss.
Though in Figure 18, be that example illustrates with casing top half 5, upper bearing (metal) 9, upper bearing (metal) binder bolt 13, but in following cylinder 6, lower bearing 10, lower bearing binder bolt 14 fixing, also can under being arranged at, on the end face of the screw section 6a of cylinder release portion be set same as described abovely, can obtain identical effect with this.
