Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Embodiment 1
Referring to Fig. 1, two-cylinder type rotary compressor 1 is made up of motor part 5 and compression mechanical part 4.Motor part 5 is made up of stator 6 and rotor 7, and rotor 7 is fixed on the bent axle 21 of compression mechanical part 4, and is as shown in Figure 2, and stator 6 is fixed in the seal casinghousing 2 with compression mechanical part 4.
Embodiment 1 characteristic is; The cylinder assembly 11 that constitutes compression mechanical part 4 centers is made up of the first cylinder 13a, the second cylinder 13b and intermediate plate 15, the accurate in advance core of transferring of this cylinder assembly 11, then; Main bearing 25 and supplementary bearing 26 are the center with cylinder assembly 11, transfer the core assembling again.
Referring to Fig. 2, shown the internal structure of compression mechanical part 4.Compression mechanical part 4, the main bearing 25 and the supplementary bearing 26 that are accommodated in first piston 17a and the second piston 17b, the first slide plate 18a and the second slide plate 18b in the first cylinder 13a and the second cylinder 13b and support bent axle 21 by cylinder assembly 11, bent axle 21, respectively constitute.Cylinder assembly 11 by the first cylinder 13a, the second cylinder 13b, and the intermediate plate 15 of dividing these two cylinders constitute.
Compression mechanical part 4 is connected by major axis screw 27 and minor axis screw 28 after accomplishing and transferring the core step securely.Simultaneously, the baffler of main bearing 25 and supplementary bearing 26 is installed respectively, in following explanation, has been omitted the drawing and the explanation of this baffler.
Bent axle 21 is made up of main shaft 22, countershaft 23, the first eccentric shaft 24a and the second eccentric shaft 24b.The first eccentric shaft 24a and the second eccentric shaft 24b are configured in the inside of the first cylinder compression chamber 14a and the second cylinder compression chamber 14b respectively, and the first piston 17a and the second piston 17b are installed on these eccentric shafts with freely rotating.And the first slide plate 18a and the second slide plate 18b that the periphery of tip and above-mentioned piston is joined are installed on the cylinder separately.
Main bearing 25 is made up of main bearing planar surface portion 25a and the 25b of main bearing portion, and supplementary bearing 26 is made up of supplementary bearing planar surface portion 26a and the 26b of supplementary bearing portion.
Constitute and assembly through above parts, accomplish the assembling of compression mechanical part 4.At last, sliding blade spring 19 is installed in the back of two slide plates after, begin to carry out arc spot welding from the external diameter of housing 2, the periphery of main bearing planar surface portion 25a is fixed on the inwall of housing 2.
Referring to Fig. 3, be the X-X cross section among Fig. 2.In two holes of the planar surface portion that is arranged at the second cylinder 13b; Have the accent core screw 12 of use on cylinder assembly 11; With five second screw 34b; See Figure 14, the bolt portion of major axis screw 27 and minor axis screw 28 combines with these second screws 34b, makes main bearing 25 be connected with cylinder assembly 11 with supplementary bearing 26.Certainly, this second screw 34b also can adopt nut to substitute.
Be not limited only to two-cylinder type rotary compressor, in the rotary compressor of other type, do not contact, between the two, need the little gap about 20～40 μ m usually at this with the inwall of cylinder compression chamber in order to make rotating piston outer wall.This gap is called the piston side clearance.
From the viewpoint of the improved efficiency of compressor, the piston side clearance changes along with the angle of revolution of piston, such as the angle of revolution is in little scope, and in the little scope of compression pressure, it is big that the piston side clearance becomes; The angle of revolution in big scope, in the big scope of compression pressure, piston side gap smaller.
Therefore, the axle core of the axle core of bent axle and cylinder compression chamber strictly speaking, is not same core, and minimum amount is arranged, such as the amount of 5～15 μ m is biased i.e. transverse direction dislocation.Therefore, in the accent core step of the bent axle of following explanation and cylinder compression chamber, above-mentioned biasing answers forethought to transfer the core instrument well.
In two-cylinder type rotary compressor; In the time of the minimum clearance of two piston external diameters and 16 formation of intermediate plate center hole; Will exist pressurized gas to be leaked to the problem of cylinder compression chamber, therefore, the diameter of expectation intermediate plate center hole 16 and the difference between the eccentric shaft external diameter can be dwindled as much as possible.Also have, existence can enlarge the method for piston thickness t, and frictional loss big, piston increases but the internal diameter of cylinder compression chamber becomes, so should avoid this method.
Referring to Fig. 4, the center of cylinder assembly 11, the first cylinder compression chamber 14a and the second cylinder compression chamber 14b is strict with, such as, remove form error after, be asked to the same core degree below the 5 μ m.And, as stated, such as, be the gap design between the intermediate plate center hole 16 and the second eccentric shaft 24b external diameter 0.1mm when following, the same core degree at the center of cylinder compression chamber and intermediate plate center hole 16 centers is all very important.In order to satisfy above precision prescribed, the first cylinder compression chamber 14a, the second cylinder compression chamber 14b and intermediate plate 15 are transferred core screw 12 to be connected by two.
As the accent core means that satisfy the height-precision requirement; For technology and pattern assembly and the gap between the cylinder compression chamber internal diameter of measuring internal diameter are disappeared; Give pressure, carry out the axle method of the accent core of two cylinder compression chambers, perhaps capable of using at the cylinder compression chamber internal diameter and transfer between the core instrument, the core regulating method of the non-contact method through pneumoelectric momentum appearance, electrical equipment amount appearance etc.
Referring to Fig. 5, two the cylinder compression chambers of center roller method and the accent core and the assembling method of intermediate plate describe.
In the central authorities that transfer core tool table 45, the cylinder assembly 11 of the temporary transient assembling of configuration.The first sliding axle 44a and the second sliding axle 44b of accent core instrument 41b that has accent core instrument 41a and second cylinder of first cylinder at tip respectively moves to the center direction of transferring core tool table 45 simultaneously; And, invade the inside of inlet casing compression chamber from towards between the internal diameter of opening portion, maintenance and the cylinder compression chamber of two cylinder compression chambers of cylinder assembly 11, existing small gap.
At this moment, be arranged on the engagement protrusion 43 and intermediate plate aligning axle 42, perforation intermediate plate center hole 16, intermediate plate aligning axle 42 and intermediate plate center hole 16 almost equal diameters of the second sliding axle 44b tip.Tip engagement protrusion 43 is chimeric with the trapezoidal hole that is arranged on the first sliding axle 44a tip, between the first sliding axle 44a and second sliding axle 44b axle core separately, small error takes place, and needs to revise.
When move stop after, be clipped in temporary transient assembling cylinder assembly 11 both sides the first block 46a and the second block 46b almost simultaneously elastic force property ground support sliding axle.What be configured in that two cylinders transfer core instrument peripheries cuts apart plate (segment), with the power of setting in advance, makes the internal diameter expansion of cylinder compression chamber separately.Simultaneously, temporary transient two of installing transfer core screw 12 to tighten the first cylinder 13a and the second cylinder 13b and be positioned at its central intermediate plate 15, and cylinder assembly 11 is connected securely, accomplish and transfer the core step.
Consequently, can the accurate same core degree of transferring the core first cylinder compression chamber 14a and the second cylinder compression chamber 14b.And, can also correctly transfer core and the compression chamber of relative these cylinders, the same core degree of intermediate plate center hole 16.
At this, like technology in the past, any one among the first cylinder 13a, the second cylinder 13b and intermediate plate 15 use the method for nothing pin, when transferring core in advance, do not need intermediate plate to transfer mandrel 42.And, if can guarantee the same core degree of the first sliding axle 44a and the second sliding axle 44b, just do not need tip engagement protrusion 43.Above-mentioned core regulating method is not limited only to the mode of Fig. 5 explanation, also automation easily.
Next, to using the cylinder assembly of transferring after core is accomplished 11, the step of accomplishing compression mechanical part 4 to describe.
In two-cylinder type rotary compressor, be designed to the diameter of the first cylinder compression chamber 14a and the second cylinder compression chamber 14b to equate; And the eccentric amount e of the second eccentric shaft 24b and the first eccentric shaft 24a, the value that is designed to equate with these outside dimension.
In Fig. 6, center line C is the center line of cylinder assembly 11, and is the center line of intermediate plate center hole 16.Under the condition of above-mentioned design size, for the second eccentric shaft 24b that makes bent axle 21 through intermediate plate center hole 16, this eccentric shaft moment the eccentric amount e of must not only setovering.
The external diameter of the first eccentric shaft 24a that form this moment and the minimum clearance w1 between the first cylinder compression chamber 14a inwall are more than zero, that is to say w1＞0.If w1＜0 o'clock, the inwall of the external diameter of the first eccentric shaft 24a and the first cylinder compression chamber 14a is interfered, and the second eccentric shaft 24b just can not pass through intermediate plate center hole 16.
Referring to Fig. 7, the state that often is in w1＞0 is described.In Fig. 6, as shown in Figure 7 after the second eccentric shaft 24b can pass through intermediate plate center hole 16, need turn back to regular position to the center of bent axle 21.That is to say, consistent for the Center-to-Center line C that makes bent axle 21, need only from the state of Fig. 6 and return eccentric amount e.Consequently, become Fig. 7.At this moment, the maximal clearance that forms between the external diameter of the second eccentric shaft 24b and intermediate plate center hole 16 internal diameters equates with eccentric amount e.
As stated, in order to prevent from piston internal leakage gas to the cylinder compression chamber, the wall thickness t of the piston that closes with the eccentric shaft cunning has to bigger than eccentric amount e, so t＞e.Consequently, in Fig. 6, can prove w1＞0.
In other words, in two-cylinder type rotary compressor, the wall thickness t of piston has to bigger than the eccentric amount e of eccentric shaft.On embodiment 1, according to this principle, can connect two cylinders and intermediate plate in advance, accomplish cylinder assembly 11.
In design in the past, consider the accent core error between intermediate plate center hole 16 and cylinder compression chamber, the diameter of intermediate plate center hole 16 will design greatlyyer than the diameter of eccentric shaft.Under such condition, compare with embodiment 1, have to design piston wall thickness t greatly, and design the internal diameter of cylinder compression chamber greatly, the reason place of compressor efficiency reduction that Here it is.
Referring to Fig. 8, following step is to transfer the step of 21 cores of core bent axle and the second cylinder compression chamber 14b axle core.
Bearing is transferred core instrument 51, is made up of axle holding part 52 and compression chamber holding part 53.The axis of these two holding parts is identical, can be flexible to center line and right angle orientation, and stretch, make the same core degree of two holding parts not change according to this.
First eccentric shaft 24a of bent axle 21 and the height center of the second eccentric shaft 24b; Be positioned at the height center consistent location with separately cylinder compression chamber, countershaft 23 and axle holding part 52 be sliding closes, the inwall of the second cylinder compression chamber 14b is slidingly matched with the outer wall maintenance of compression chamber holding part 53.
Thereafter, the internal diameter of axle holding part 52 dwindles, and the external diameter of compression chamber holding part 53 enlarges, and keeps this state.In above step, accomplish the accent core of bent axle 21, the second cylinder compression chamber 14b and the first cylinder compression chamber 14a.
Referring to Fig. 9, as following step, be installed in first piston 17a on the first eccentric shaft 24a, be installed in the first slide plate 18a on the first cylinder 13a.At this moment, in preceding step, accomplished the accent core of the bent axle 21 and the first cylinder compression chamber 14a, so can correctly transfer the piston side clearance that forms between the internal diameter of external diameter and the first cylinder compression chamber 14a of core first piston 17a.Till following following step, can keep this state.
Referring to Figure 10, as following step, insert main bearing 25 in the main shaft 22, contact under the state on the first cylinder 13a closely at main bearing planar surface portion 25a, use five major axis screws 27, be installed on the second screw 34b of the second cylinder 13b.Consequently, accomplish being connected of cylinder assembly 11 and main bearing 25.
Referring to Figure 11, as following step, remove bearing and transfer the maintenance of core instrument 51 to the countershaft 23 and the second cylinder compression chamber 14b, remove bearing and transfer core instrument 51., be installed in second piston 17b second eccentric shaft 24b on, be installed in the second slide plate 18b on the second cylinder 13b thereafter.
Referring to Figure 12,, insert supplementary bearing 26 in the countershaft 23 as following step.At this moment, use two to three minor axis screws 28, temporarily install, supplementary bearing 26 is contacted with the second cylinder 13b closely.Need to countershaft 23 and supplementary bearing portion 26b separately axle core transfer core thereafter.Its reason is, between the inwall of the outer wall of main shaft 22 and the 25b of main bearing portion, between the inwall of the outer wall of countershaft 23 and the 26b of supplementary bearing portion, have the bearing play about 15～30 μ m at the diameter place.
For the axle core that makes countershaft 23 and main shaft 22 can be correctly matches with the center in this associated bearings gap; Through making the revolution of main shaft 22 low speed; At the minor axis screw 28 of the less temporary transient installation in position of rotary torque, with fixed moment of torsion installation, be installed in supplementary bearing 26 on the second cylinder 13b.And, through the minor axis screw 28 that keeps, the second cylinder 13b and supplementary bearing 26 are installed, be connected cylinder assembly 11 securely with supplementary bearing 26.
In above-mentioned steps, finish the accent core step of cylinder assembly 11, main bearing 25 and supplementary bearing 26, accomplish compression mechanical part 4.Be slidedly assemblied in bent axle 21 in the above-mentioned bearing, under correct position, also can turn round with two pistons of bent axle 21 interlocks.
