Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Like Fig. 1, Fig. 2 and shown in Figure 3; Hidden quiet dish in the drawings to show internal structure of the present invention; The present invention includes driving mechanism 1, by the compressing mechanism 2 that the acting position 211 and the quiet dish of Moving plate 21 constitutes, said compressing mechanism 2 is provided with suction port 23, driving mechanism 1 cooperates with drive compression mechanism 2 with Moving plate 21; Said compressing mechanism 2 is provided with even number; The compression direction of said compressing mechanism 2 is identical and be set up in parallel along the axis of compressing mechanism 2, and on the circumferencial direction of compressing mechanism 2, the compressing mechanism 2 of half quantity is opposite with suction port 23 opening directions of the compressing mechanism 2 of second half quantity.Fixing involute vortex forms Vorticose space on the acting position 211 of Moving plate 21 and the quiet dish; Driving mechanism 1 converts the rotation of power source translation into and passes to Moving plate 21; In the translation process of Moving plate 21; Thereby compression is accomplished in this space constantly compression, thereby if air inlet, compression and three processes of exhaust are just carried out in Moving plate 21 then this spatial spread air inlet of translation in opposite direction in the course of the work.Compressing mechanism 2 of the present invention is provided with a plurality of, and arranges along axial direction each other.On the space that Moving plate 21 and quiet dish form, a suction port 23 is arranged, just the suction port 23 of compressing mechanism 2.The quiet dish of compressing mechanism 2 is to be fixed on the corresponding fixing device.Because the opening direction of the suction port 23 of the compressing mechanism 2 of half quantity and second half quantity in opposite directions; Just on the circumference of compressing mechanism 2, suction port 23 openings of half quantity are towards clockwise, and the suction port 23 of second half quantity is towards counterclockwise; The Moving plate 21 of all compressing mechanisms 2 interconnects to guarantee motion consistent; When all compressing mechanisms 2 were arranged side by side, compressing mechanism 2 suction ports 23 opening directions that can be adjacent were opposite, also can be opposite at interval.Accomplish compression at compressing mechanism 2; During the beginning air inlet; Since the suction port 23 of the compressing mechanism 2 of half quantity and second half quantity towards on the contrary, so the moment of reaction of medium generation when getting into suction port 23 just cancels out each other, these compressing mechanisms 2 have identical compression direction; Promptly at Moving plate 21 when compression direction moves, all compressing mechanisms 2 are all carrying out compressed action.Visible by said structure; The present invention can offset the reaction force that compressing mechanism 2 is produced in the intake process medium greatly; So just can be so that compressing mechanism 2 is installed on the fixing device more steady; Neither damage can be caused, also rocking of compressing mechanism 2 can be do not caused because of becoming flexible because of long term.
Concrete, as shown in Figures 2 and 3, on the circumferencial direction of compressing mechanism 2, on the circumferencial direction of compressing mechanism 2, suction port 23 opening directions of adjacent two compressing mechanisms 2 are opposite.Because all suction ports 23 are not or not a plane; Therefore can be to the joint generation moment of torsion of compressing mechanism 2 with fixing device; The suction port 23 of adjacent two compressing mechanisms 2 is at a distance of nearer, so its moment of when air-breathing, cancelling out each other is less to the torque influence that the fixing device joint produces.The angle of 180 degree makes adjacent two suction ports 23 farthest apart, thereby can reduce the phase mutual interference when air inlet.
As preferred implementation of the present invention, as shown in Figures 2 and 3, the formed angle of suction port 23 opening directions of adjacent two compressing mechanisms 2 is 180 degree.Adjacent two identical compressing mechanisms 2 misplace in the plane 180 the degree.Mean that promptly Moving plate 21 is opposite with the spatial form that quiet dish forms; If the space of compressing mechanism 2 on the left sides is compressed, then the space on its adjacent compressor structure 2 the right is compressed, and these two spaces are identical; Therefore; The reaction force that in compression process, produces is cancelled out each other, and the active force that in like manner produces in the space at other position also can receive the counteracting of the active force of adjacent compressor structure 2 generations, removes the space at the axis place; Also can be like this at breathing process.Therefore; After adopting said structure, can alleviate because the reaction force that compressing mechanism 2 work are produced, prevent that being connected between compressing mechanism 2 and the fixing device is damaged; And after having alleviated internal force; The volume of compressing mechanism 2 can be provided with greatlyyer, both can improve volume of the present invention through the quantity that increases compressing mechanism 2, also can increase compressing mechanism 2 and improve volume of the present invention.
In order to simplify structure of the present invention, like Fig. 1 and shown in Figure 4, compressing mechanism 2 is provided with two, and two compressing mechanisms 2 are made up of a Moving plate 21 and two quiet dishes, and the both sides of Moving plate 21 are respectively arranged with the acting position 211 that is complementary with quiet dish.Only need a Moving plate 21 this moment, only need process respectively 211, two actings position 211, corresponding acting position and match with corresponding quiet dish respectively again and form two compressing mechanisms 2 in the both sides of Moving plate 21.So just, can simplified structure, reduce the making amount of Moving plate 21, also practiced thrift material, alleviated whole quality, this has also alleviated the pressure to fixing device after installation.
For medium in the balance zone of high pressure to the reaction force of Moving plate 21, as shown in Figure 5, the zone of high pressure of two compressing mechanisms 2 is interconnected.In the process of compression, compressing mechanism 2 is compressed to the zone of high pressure with the medium in its space, the zone that the zone of high pressure is the last space that compressing mechanism 2 is compressed to medium and prepares to discharge; Pressure at the medium of zone of high pressure is maximum, and therefore in compression process, medium can produce bigger active force to Moving plate 21; But because the zone of high pressure is interconnected; The active force that is positioned at the zone of high pressure generation of Moving plate 21 both sides is cancelled out each other, thereby has alleviated the active force that Moving plate 21 receives, and helps the working life of Moving plate.
Concrete, as shown in Figures 2 and 3, the zone of high pressure that Moving plate 21 centers are provided with 212, two compressing mechanisms 2 of through hole is interconnected through through hole 212.Certainly, also can adopt special-purpose pipeline to be communicated with.
In order to reduce the wearing and tearing of 1 pair of Moving plate 21 of driving mechanism; Like Fig. 1 and shown in Figure 4; Driving mechanism 1 comprises driving shaft crank throw 12 and the gear frame 13 on driving shaft bent axle 11, the driving shaft bent axle 11; Said gear frame 13 is arranged on driving shaft crank throw 12 places and matches with it, and this gear frame 13 interconnects with Moving plate 21.Driving Moving plate 21 when quiet disk axis is done the revolution translation; Driving shaft bent axle 11 drives gear frame 13 through driving shaft crank throw 12 and does revolution motion around driving shaft bent axle 11 axis; Gear frame 13 can cooperate with driving shaft crank throw 12 through parts such as bearings; Driving shaft bent axle 13 axis are coaxial with quiet disk axis, and gear frame 13 interconnects with Moving plate 21, and Moving plate 21 can be done the revolution motion identical with gear frame 13.At this moment, driving shaft bent axle 11 no longer directly acts on Moving plate 21, thereby can effectively reduce the wearing and tearing to Moving plate 21, reduces the maintenance to Moving plate 21, only needs that gear frame 13 is done maintenance and gets final product.
In order to increase the accuracy of driving mechanism 1 transmission; Like Fig. 1 and shown in Figure 4, gear frame 13 is provided with at least one driven shaft 14, and driven shaft 14 is by 11 transmissions of driving shaft bent axle; Its velocity ratio is 1:1; Driven shaft 14 is provided with eccentric wheel 15, and eccentric wheel 15 has identical throw of eccentric and angular orientation with driving shaft crank throw 12, and driven shaft 14 matches with gear frame 13 through eccentric wheel 12.When work; Drive power source driving shaft bent axle 11 rotates; Driving shaft bent axle 11 1:1 transmission is again given driven shaft 14, and driving shaft bent axle 11 can pass through the kinds of drive such as gear, bent axle, chain with driven shaft 14, owing to the driving shaft crank throw 12 on the driving shaft bent axle 11 has identical throw of eccentric and angular orientation with eccentric wheel 15 on the driven shaft 14; Therefore they are identical with revolution motion that gear frame 13 cooperations are converted into; Even one of them in driving shaft crank throw 12 or the eccentric wheel 15 be inaccuracy because wear and tear, other driving shaft crank throw 12 or eccentric wheel 15 also can be revised the motion of gear frame 13, thereby guarantee accurately carrying out of motion.This is for large-scale symmetric type scroll compressor main frame, and more driven shaft 14 can also disperse stressed, avoids gear frame 13 owing to the stressed concentrated infringement that causes.
In order to make the transmission between driving shaft bent axle 11 and the driven shaft 14 steady more continuously; As shown in Figure 4; Driving shaft bent axle 11 carries out transmission with driven shaft 14 through bent axle, and said driving shaft bent axle 11 has identical throw of eccentric and angular orientation with crank throw on the driven shaft 14 with driving shaft crank throw 12.At this moment, the motion of bent axle is identical with the motion of driving shaft crank throw 12, and the motion of whole driving mechanism 1 is more neat.
As shown in Figure 1, driven shaft 14 is provided with the 2-4 root and on gear frame 13, circumferentially evenly distributes, and its center is the axle center of driving shaft bent axle 11.
