The part such as disk 10, balanced component 11 and anti-rotation component 12, sealing strip 13 (not identified in Fig. 1, Fig. 2, refer to Fig. 4).Below
It will be described in detail for above-mentioned each part.
The vortex dry vacuum pump includes the fixed scroll 2 and orbiter 10 being oppositely arranged, and fixed scroll 2 includes quiet
Vortex, orbiter 10 include dynamic vortex body, wherein, the molded line of static vortex and the molded line of dynamic vortex body use A Ji meter
Moral vortex lines, the phase difference between the molded line of dynamic vortex body and the molded line of static vortex with 180 °, dynamic vortex body is vortexed with quiet
Body can engage to form compression chamber.The vortex dry vacuum pump by optimize the molded line of static vortex and dynamic vortex body design and
Processing scheme, on the premise of reduction difficulty of processing and processing cost, meets the performance of vortex dry vacuum pump product and uses
It is required that.
Preferably, the molded line of the molded line of the static vortex of the present embodiment mesoscale eddies dry vacuum pump and dynamic vortex body is used
The mating connection of Archimedes's vortex lines and secondary Archimedes's vortex lines, head uses secondary Archimedes's vortex lines,
Afterbody is using Archimedes's vortex lines, and the junction of Archimedes's vortex lines and secondary Archimedes's vortex lines has
Continuous first order derivative and second derivative.
In the present embodiment, the involute of circle of the prior art is replaced to design dynamic vortex using Archimedes's vortex lines
Disk 10, the molded line of fixed scroll 2 are based on following reasons：Realizing the necessary condition of scroll vacuum pump normal work in theory is, moves
Scroll plate 10 can be engaged with the vortex of fixed scroll 2 in compression chamber, i.e., the static vortex of fixed scroll 2 is in compression chamber
Certain point, must have a little corresponding to therewith on the dynamic vortex body of orbiter 10, and realize instant contact, Archimedes is vortexed
Line and its equal space line can meet the requirement；Simultaneously, it is contemplated that orbiter 10, the processing of the molded line of fixed scroll 2, it is final to determine
The scroll molded line of orbiter 10, fixed scroll 2 is set up using Archimedes's vortex lines.
When vortex dry vacuum pump is run, although orbiter 10, fixed scroll 2 need to realize instant contact in theory, but
Due to mismachining tolerance, rigging error etc. exist, in actual motion orbiter 10, fixed scroll 2 instant contact it is impossible
Realize, thus a slot reservation number be the factor for reaching that this index of its final vacuum is the most key, gap is excessive, can cause
Its final vacuum is difficult to reach；And gap is too small, can occur friction even between orbiter 10, fixed scroll 2 during operation
Occlusion, causes temperature to steeply rise, is greatly reduced the efficiency of vortex dry vacuum pump, or destruction orbiter 10, quiet whirlpool
Wall between capstan 2, cause vortex dry vacuum pump kills failure.
Consider, the scroll molded line that orbiter 10, fixed scroll 2 are finally used in the present embodiment is not to enter
The Archimedes's vortex lines and its equal space line of row instantaneous touch, but select the Archimedes's vortex lines and two for being adapted to processing
Secondary Archimedes's vortex lines replace its equal space line.Because the gap change of the initial segment is generally than larger, it may appear that gap is zero very
The possibility most born；Also, because head is in the initial segment of scroll molded line, it is easy to produce the knife that allows of stress deformation and cutter
Phenomenon, need to thicken and correct, and be used cooperatively using secondary Archimedes's vortex lines；Tail radius is than larger, therefore radius of curvature
Change is smaller, is used cooperatively using Archimedes's vortex lines, and Archimedes's vortex lines and secondary Archimedes are vortexed
The junction of line need to ensure once to lead and it is secondary lead it is all continuous.
Wherein, gap is reserved between static vortex and dynamic vortex body, gap is gradually successively decreased from outer ring to inner ring, and inner ring
Gap keeps definite value.It may further be preferable that the unilateral interstice coverage reserved between static vortex and dynamic vortex body is 0.03mm
~0.02mm, namely the unilateral gap of the inner ring of centremost inner ring and subcenter is about 0.02mm.
Orbiter 10, the vortex of fixed scroll 2 can not possibly be substantially parallel, and be with orbiter 10 during due to operation
Central axis as benchmark, the nonparallelism of outermost end can be bigger than middle, therefore the reserved gap of outermost end is maximum, inwardly
Gradually successively decrease；And during due to operation, center section temperature rise ratio is very fast, heat affecting is the two of the inside in innermost end than larger
Ring gap is no longer reduced, and keeps constant value, by theoretical calculation and verification experimental verification, the pre- allowance in unilateral gap 0.02mm~
It is the most suitable between 0.03mm.Therefore, static vortex and dynamic vortex body finally using Archimedes's vortex lines and secondary Ah
Base Mead vortex lines are used cooperatively, and reserved gap is maximum in outmost turns, inwardly gradually successively decreases, unilateral gap is also by extroversion
Inside gradually successively decrease, such as unilateral interstice coverage changes between 0.03mm~0.02mm.
According to the operation principle of vavuum pump, closing chamber (namely compression chamber) is transported with orbiter 10, fixed scroll 2
Formed when dynamic, therefore orbiter 10, fixed scroll 2 are the core parts of scroll vacuum pump, with higher morpheme essence
Degree and dimension precision requirement.In the prior art, the processing to orbiter 10, fixed scroll 2 is substantially setting with costliness
Processed for such as millions of specialized working machine tool of machine, to ensure its precision.
As it was previously stated, the vortex dry vacuum pump includes motor and contiguous block 3, anti-rotation component 12, motor has inclined
Electrocardio arbor 9, orbiter 10 is arranged on eccentric motor axle 9, compared with prior art in pass through eccentric stiffener (such as bent axle)
To form the mode of eccentric drive shaft, the drive shaft of the motor of the present embodiment is machined directly to eccentric shaft so that assembly difficulty is big
It is big to decline.Contiguous block 3 is arranged on electric machine casing 6, and fixed scroll 2 is arranged on contiguous block 3；Anti- rotation component 12 and dynamic whirlpool
Capstan 10 and contiguous block 3 are connected simultaneously, and anti-rotation component 12 causes orbiter 10 can be relative under the drive of eccentric motor axle 9
Translational motion is done with the Circular test of the eccentric throw formation of eccentric motor axle 9 in fixed scroll 2.
In the vortex dry vacuum pump, the theoretical barycenter of orbiter 10 is on rotation centerline；And the vortex dry type is true
Empty pump includes balanced component 11, and balanced component 11 includes two pieces of independent balance weights, and two pieces of balance weights set up separately in eccentric motor axle 9
Close to contiguous block 3 and close to the region of back end cover for motor 7.In vacuum pump operation, orbiter 10 is kept in motion, therefore
Orbiter 10 itself need to keep balance, and scroll molded line is asymmetric, therefore can pass through when designing orbiter 10
Remove non-usage facestock material method so that the theoretical barycenter of orbiter 10 at the center line on.Because orbiter 10 is pacified
Mounted in the eccentric position of eccentric motor axle 9, static unbalance and unbalancing value are very big, therefore also devise two pieces of balances simultaneously
Block, to realize static unbalance and the unbalance dynamic of fixed scroll 2 and orbiter 10, but due to the presence of mismachining tolerance, in dress
Dynamic balancing is done with also needing to simulate the real motion of eccentric motor axle 9, orbiter 10 and balance weight with special frock before
Experiment, standard need to reach G6.3 grades.
The present embodiment is while the structure of the vortex dry vacuum pump is provided, in order to more clearly introduce related keyword
The forming process of structure, has also correspondingly provided a kind of manufacture method of vortex dry vacuum pump.
The manufacture method of the vortex dry vacuum pump includes processing and forms the fixed scroll 2 and orbiter 10 being oppositely arranged
The step of, fixed scroll 2, which includes static vortex, orbiter 10, includes dynamic vortex body, the molded line and dynamic vortex body of static vortex
Molded line use Archimedes's vortex lines, there is 180 ° of phase between the molded line of dynamic vortex body and the molded line of static vortex
Difference；Wherein, Archimedes's vortex lines of static vortex and dynamic vortex body are formed using Milling Machining, and during Milling Machining milling cutter to revolve
Switch to main motion, feed motion is moved and realized by the working shaft rotation of rotary table and the working shaft of milling machine horizontal table.
Wherein, during Archimedes's vortex lines of processing static vortex and dynamic vortex body, the work of rotary table
Forward or reverse is remained as axle, the working shaft of milling machine horizontal table only realizes feed motion in a direction movement；
During the Archimedes's vortex lines for finishing static vortex or dynamic vortex body, the working shaft commutation of rotary table is once.
To be further ensured that machining accuracy, the Milling Machining of static vortex and dynamic vortex body also includes, and is detected and mended by laser interferometer
The positioning of the working shaft of horizontal table and the working shaft of rotary table is repaid, wherein positioning precision is 0.005mm, resetting
Precision is 0.003mm；The positioning precision of the working shaft of rotary table is 7 ＂, and repetitive positioning accuracy is 4 ＂.
Specifically, in the present embodiment vortex dry vacuum pump, orbiter 10, fixed scroll 2 are as a result of A Ji meter
Moral vortex lines, and Archimedes's vortex lines performances of itself determines that scroll plate milling cutter in finishing can be transported based on rotation
Dynamic, feed motion is the rotation of C axles and the mobile realization of milling machine X or Y workbench by circular table, and the synthesis of the two motions is with regard to shape
Into Archimedes's vortex lines.In the prior art, round involute determines that scroll plate when using Four-axis milling, can only make
Fitted with Archimedes's vortex lines come.And the processing method that the present embodiment scroll vacuum pump is used is, adopted during processing vortex
It is that (Y workbench need to carry the weight of X workbench to the rotation of C axles below X workbench with X workbench with four-axle linked lathe
Amount, ratio of inertias X workbench is big, and positioning precision etc. is also lower than X) mobile realization, and can be matched with vortex lines design, it is to avoid adopt
The reversing error (this application condition of high precision machine tool is small) produced with X, Y interpolation, the lathe used is domestic lathe (such as knob
Prestige VM903H lathes), the accuracy class of this lathe key position in the fabrication process is improved, because the processing method of use is only used
To X-axis and C axles, detected by laser interferometer and X-axis positioning precision 0.005mm, repetitive positioning accuracy 0.003mm after compensating,
Additional Taiwan high precision turntable is as C axles, and positioning precision is 7 ＂, and repetitive positioning accuracy is 4 ＂, and uses suitable processing technology
Method, processes the part for meeting required precision.
It can be seen that, the most key part of the processing method is that requirement C axles infinitely angle can rotate, i.e., C axles are in processing one
Forward or reverse is remained during the vortex lines of side, during whole vortex is finished, X-axis or C axles can not be kept away
Once, the error produced through the C axles commutation that converts is smaller than X-axis for the need commutation exempted from, therefore selection C axle commutations.In order to avoid model
Error is produced when being converted between software, scroll plate is modeled using UG and nc program is generated, due to this processing
Y-axis can not be contained in program, therefore the establishment and post processing of program have sizable difficulty.The program track of establishment need to be carried out
Modification and optimize, what is now generated is X, Y interpolation and without the cls files of post processing, with VC++6.0 software programmings generate X,
The post processing program of C interpolations processing, is converted into radius and angle, due to this four axles lathe by the position coordinates in cls files
It is that the control program rotated with A axles is transformed, therefore C must be replaced to recognize with A in NC programs.It is vortexed in only processing
Body, on the premise of not considering that design of part causes deformation, as shown in figure 3, being the orbiter 10 after lathe four axis processing
Outer, inner side profile error schematic diagram, it is seen then that the wheel of on the outside of the orbiter processed using the processing method and inner side
In the measurement of wide degree, the profile error in outside is 0.01mm, and the profile error of inner side is 0.009mm.
Using the processing method, not only scroll plate machining accuracy is high, and production cost substantially reduces that (lathe used is total
Price is less than 600,000 yuan).
In the vortex dry vacuum pump, dynamic vortex body be arranged in parallel with static vortex, between dynamic vortex body and static vortex
The depth of parallelism be less than or equal to 0.005mm.As it was previously stated, the vortex dry vacuum pump includes motor, motor has eccentric motor axle
9；Contiguous block 3 is fitted together with electric machine casing 6 by interference fits, eccentric motor axle 9 by bearing and back end cover for motor 7,
Contiguous block 3 is fitted together, and eccentric motor axle 9 is connected as outside with the bearing of contiguous block 3 and is connected, and eccentric motor axle 9 is with being connected
The bearing outside diameter that block 3 is connected is more than the bearing outside diameter of eccentric motor axle 9 and back end cover for motor 7, eccentric motor axle 9 and contiguous block 3
The axiality of bearing hole (uses automatic tool changer mode, axiality is basic within 0.02mm between back end cover for motor 7 before improving
It is extremely difficult to 0.03mm).
The manufacture method also includes the assembling of fixed scroll 2 and orbiter 10, and fixed scroll 2 is assembled by contiguous block 3
On electric machine casing 6, orbiter 10 is assemblied on eccentric motor axle 9.For ease of mechanically connecting, contiguous block 3 and electric machine casing 6
Between bearing hole be first axle bearing bore, first axle bearing bore embeds steel bushing；The bearing hole that eccentric motor axle 9 is connected with contiguous block 3
For second bearing hole, first axle bearing bore and second bearing hole are formed using boring cutter, and the knife bar material of boring cutter is hard alloy.
Processed for the ease of boring cutter, the external diameter of first axle bearing bore is less than the external diameter in second bearing hole；Specific processed
Cheng Zhong, after first axle bearing bore is formed, continuously forms second bearing hole by the way of manual tool changing, and processing is kept during manual tool changing
The point X of position, Y-coordinate are constant, only change Z coordinate value, the axiality in first axle bearing bore and second bearing hole 0.02mm with
It is interior.
In addition, (fixed scroll 2 is set positioning hole when fixed scroll 2 is assembled with contiguous block 3 with corresponding on contiguous block 3
Put) it is symmetrically arranged two, the line of two positioning holes centers passes through the center line in second bearing hole and two positioning hole phases
It is symmetrical for the center line in second bearing hole.In specific process, two positioning holes are beforehand with frock so that two fixed
The line at Wei Kong centers is parallel relative to X-axis, and carries out X-axis interpolation, then carries out the processing of two positioning holes, two positioning holes
Symmetry be 0.01mm within.
Specifically, as shown in figure 4, the vortex of orbiter 10, fixed scroll 2 needs parallel, such as quiet vortex after mounting
The vortex of disk 2 and orbiter 10 is not parallel, then between the engagement place molded line that can cause orbiter 10, fixed scroll 2
Radial clearance half becomes big half and diminished, and change can then cause tangentially to leak, diminish greatly, is possible to that orbiter 10 can be caused, quiet
The mutual frictional heat of scroll plate 2 causes deformation or even is engaged, and causes product not run normally.In order that orbiter 10,
The depth of parallelism need to then need to ensure that motor has assembled rear eccentric motor the vortex of fixed scroll 2 within 0.005mm after mounting
Axle 9 is vertical with fixed scroll 2 and contiguous block 3 reference plane for being engaged place, and perpendicularity must be within 0.005mm, namely requires
After motor has been assembled, the axiality between two holes of two bearing block dress bearings need to be reached within 0.02mm.According to existing skill
The conventional assembly method of art, having assembled rear axiality can have 0.05mm just all well and good.Back end cover for motor 7, motor in so Fig. 1
The machining accuracy of housing 6 and contiguous block 3 particularly coaxial accuracy requires very high, and this brings very big difficulty to processing.
General electric machine structure is in order to dust-proof etc., and bearing is all mounted in the inner side of motor, and the size being just as, due to two
Bearing hole is not to process together, therefore coaxial accuracy between the two is not very high, does not reach vavuum pump institute
The requirement used.
During bore hole, the diameter for the cutter head of the boring cutter of processing need to be consistent with the size in the hole to be processed.Through
Cross and consider, the vortex dry vacuum pump of the present embodiment uses assembling mode as shown in Figure 5, because right side also needs to install
Other parts, therefore position of bearings direction can be designed to outwards, and pass through and select bearing not of uniform size, it is ensured that follow-up
Production in can use overall processing method, guarantee to be processed and formed at one time with this, the bearing rib diameter (example of right-hand member
Such as Ф 46) it is more than the bearing that left end is used (such as external diameter is Ф 40).It therefore, it can after structure as shown in Figure 5 has been assembled,
Further play the bearing hole (Ф 40) of processing left end and for the end for the peaceful right-hand member in hole such as (Ф 52) for assembling orbiter
Face, the problem of interference is not present due to this processing mode, therefore can preferably ensure axiality, perpendicularity etc., and also
Other holes for having axiality requirement to the hole for assembling orbiter can be processed together, for example：For fixed scroll 2 and contiguous block
3 assembling bearing hole (such as 2- Ф 6) and the assembling bearing hole (such as 3- Ф 19) for anti-rotation component 12 and contiguous block 3,
Meet requirement used in vavuum pump.Further, since assembling eccentric motor axle 9 etc. is also needed, therefore after mounting before overall processing
Also need with dowel hole is beaten, to reach the purpose of resetting.
During using assembling mode as shown in Figure 5, during overall processing is carried out, because the holes of Ф 40 have embedded steel
Set, and have 200mm deep away from right side, the rigidity of boring cutter need to be especially good during this hole of boring, therefore selects BIG boring cutter, and knife bar material is
Hard alloy, to avoid because rigid deficiency causes knife bar to tremble during processing, influences machining accuracy.Due to the Hes of Ф 40
The sizes of Ф 52 are different, therefore need tool changing during this holes of boring, according to the mode of automatic tool changer, that is, refer to first boring Ф 40 and Ф
The knife in 52 holes is all first attached in the tool magazine of lathe, and automatic tool changer, the rear holes of boring Ф 52 are controlled by machine tool program behind the complete holes of Ф 40 of boring.
As shown in fig. 6, must arrive during due to lathe automatic tool changer the position specified could tool changing, therefore behind the complete holes of Ф 40 of boring, pass through
Walk X, Y to be incorporated into up to tool changing point, changed after knife and returned to the holes of processing stand position boring Ф 52, the repetition that such a method is related to lathe is determined
Position precision, it is 0.03mm or so that the axiality of holes is measured after processing.It is preferred to use the complete holes of Ф 40 of the mode of manual tool changing, i.e. boring
Afterwards, keep processing stand position X, Y-coordinate constant, only become Z coordinate values, when boring cutter reaches home, manual tool changing, boring Ф
52 holes, the axiality that holes is measured after processing is 0.016mm, i.e., when using manual tool changing, can avoid because resetting is drawn
The error risen.
The method is equally used for the holes of processing 2- Ф 6, because 2- Ф 6 are positioning when fixed scroll 2 is assembled with contiguous block 3
Hole, therefore required precision is especially high, the line of two positioning holes centers need to be by the center line in the holes of Ф 52, and relatively in theory
Center line in the holes of Ф 52 is symmetrical.If at will look for individual position placement overall processing part, X, Y-axis need to be walked during boring 2- 6 holes of Ф same
When interpolation, if being beforehand with frock so that the line for this two positioning holes center that need to be processed is parallel relative to X-axis, then can only walk X
Axle interpolation, it is to avoid requirement to Y axle positioning precisions, experiment proves that, when using the interpolation simultaneously of X, Y-axis symmetry for
0.02mm or so, and X-axis interpolation is used, symmetry can drop to below 0.01mm.

Therefore the micropore inside bipeltate will swell, and produce upward top power, and pressure differential is bigger, then the power of upward jack-up is also got over
Greatly so that sealing strip 13 is brought into close contact with the end face coordinated, sealing is realized, therefore the power of jack-up needs control upwards, can neither
It is too big, can not be too small, it is computed finding, when the density range of bipeltate is 160~230kg/m3When can preferably meet
Use requirement, when part wears occurs in the high-abrasive material of the use ultra-high molecular weight polyethylene formation in upper strata, due under
The presence of the jack-up power of the use fretting map rubber elastomer of layer, with certain compensating action, therefore the life-span of sealing strip 13
Can be long.
