Specific embodiment
For the not high technical problem of the protection coating Forming Quality of pole piece in the prior art, the application's is practical new
Type people has carried out a large amount of experimental study and theory analysis by taking outer rotor as an example, proposes one kind and is able to solve magnetic pole and magnetic yoke wall
The filling problem in the gap between gap, magnetic pole and magnetic pole, between magnetic pole and press strip improves magnetic pole and protects coating Forming Quality,
Improve the technological equipment of reliability of technology.
The utility model people of the application is found through experiments that, protection coating is formed in the state of placing rotor vertically
There are bonding agent Radial Flow Through Porous Media later stage missing in technique, the various problems such as gap filling quality are not can guarantee.
By having carried out a large number of experiments for resin is perfused, it is found by experiment that:It places and grasps in rotor vertical axes
When making to carry out vacuum infusion resin on platform, still have " vacuole " apart from lower end one third region, and there is protection
Coating in axial direction uneven thickness, the larger phenomenon of lower cladding thickness.In the reinforcing material glass-fiber-fabric different using density
As a result it also has any different.
For above-mentioned experimental phenomena, the utility model people of the application has made intensive studies and analyzes.By rotor axial
In the state of vertical placement, the lower part of perfusion die cavity is arranged in gum-injecting port, and the top of perfusion die cavity, bonding agent is arranged in bleeding point
From lower part toward top seepage flow.Pressure near gum-injecting port is close to environmental pressure, and the pressure near the bleeding point on top is close
In the reading of the vacuum meter of vacuum pump.Therefore, the inside and outside differential pressure of vacuum bag lower part is less than the inside and outside differential pressure on vacuum bag top, from
And to bonding agent, seepage flow causes certain obstruction from the bottom up.At the same time, due to the axial direction along rotor, to viscous
Connect dosage form at radial pressure difference it is serious inconsistent so as to lack seepage flow in radial directions dynamic for the bonding agent of rotor lower area
Power, it is difficult into the narrow gap between magnetic pole 43, press strip 42, magnetic yoke 41, especially be difficult to cross magnetic pole 43 and press strip 42
Into in the gap between magnetic pole 43 and magnetic yoke 41.Simultaneously as gravity is further slackened from vertical, gravity drainage effect
The effect of bonding agent Radial Flow Through Porous Media, the bonding agent for being less useful for magnetic pole and magnetic yoke wall gap are filled, especially radially the seepage flow later period
Pressure missing causes to form starved gap between magnetic pole 43 and magnetic yoke 41, becomes the security risk that magnetic pole falls off.
In addition, previously having carried a large amount of air, vapor in the reinforcing materials such as glass-fiber-fabric.Also, between magnetic pole and magnetic pole
Gap, the gap between magnetic pole and press strip, in the gap between magnetic pole and magnetic pole plug also adsorb air, vapor.It is attached
Water in reinforcing material will gasify for 43 DEG C under vacuum, therefore, the solid components in priming by vacuum die cavity carries
Aqueous vapor, bubble is gasificated as when vacuumizing.In addition, water can be such that the sizing material of isocyanate groups solidifies, and it is accompanied by two
The release of carbonoxide, causes foamed polymer to be formed.Therefore, bonding agent cannot well seepage flow to and fill magnetic pole gap, institute
Bubble easy to form and hole in the protection coating of formation.
By a large number of experiments, rotor is vertical in the prior art, static placement progress vacuum is auxiliary for the utility model discovery
When helping form, flowing trace of the bonding agent in protection system has certain rule.Fig. 5 shows rotor and exists
Vertically, in the case where static placement, during forming protection coating using vacuum auxiliary pouring and molding technique, bonding agent is being filled out
Fill the schematic diagram of the flow trace during gap.
As seen in Figure 5, bonding agent has following several situations to occur in flow process:
(1) there is circumferential section region and axially flows in circle distribution in the bonding agent of magnetic yoke wall and magnetic pole gap
Speed is faster than above magnetic pole radial the speed between reinforcing material and vacuum bag film, and bonding agent is axially flowed along gap, and
It takes the lead in overflowing the gap between the top layer of magnetic pole 43 and magnetic yoke 41.That is, bonding agent is flowed along the track A-F-E-B, in space
Whether there is bonding agent seepage flow between position E and C, between F and D, pass through magnetic pole gap, is all unable to control.
Bonding agent self gravity direction and bonding agent are perpendicular along rotor magnetic pole radial dipping direction;Radial Flow Through Porous Media
Pressure from vacuum bag film 50 to the radial pressure of protection system, when vacuum bag film 50 compresses protection system, pressure is transferred to
When 43 surface of magnetic pole, when the volume that protection system occupies no longer reduces, radial pressure is promoted to glue by the radial complete equipilibrium of magnetic pole 43
It connects agent and enters magnetic pole gap, the motive force disappearance into E, F area of space, it is difficult to cross magnetic pole and press strip enters magnetic pole and magnetic yoke
Gap between wall.Because taking the lead in having bonding agent filling in E, F area of space, these bonding agents fill E, F spatial joint clearance, lead
The pressure for causing the later period of the bonding agent Radial Flow Through Porous Media (by the region C to E, D to F) of protection system to push bonding agent flowing weakens very
To disappearance, the gap glued dose of filling completely in protection coating molding space can not be ensured.
(2) there is circumferential section region and axially flows in circle distribution in the bonding agent of magnetic yoke wall and magnetic pole gap
Speed is slower than above magnetic pole radial the speed between reinforcing material and vacuum bag film, and bonding agent is along flow-guiding screen along motor pole
Surface is axially flowed, and takes the lead in overflowing magnetic pole top layer region.I.e.:It is flowed along the track A, D, C, B;Spatial position A, F, E
The gap area in direction is still filled without glued dose, and can bonding agent radially pass through magnetic pole gap and magnetic pole and pressure
Gap between item, so that seepage flow is between C and E, between D and F, requiring that bonding agent is waited to pass through along axial seepage flow, dipping
Extra bonding agent fills up radial clearance after composite protective coating molding space.Bonding agent self gravity direction and bonding agent edge
Rotor magnetic pole radial dipping direction it is perpendicular, can not to bonding agent Radial Flow Through Porous Media provide driving force;The drive of Radial Flow Through Porous Media
Power is from vacuum bag film 50 to the radial pressure of protection system.After vacuum bag film 50 compresses protection system gradually, along electricity
Arbor to flowing and be introduced into the bonding agent in vacuum bag 50 can it is fewer and fewer until stagnate so that bonding agent quality cannot get
Supplement.In the case where vacuum pump continues working, when pressure is transferred to magnetic pole surfaces, the volume that protection system occupies is not reducing
When, radial pressure is passed through magnetic pole and magnetic pole gap is promoted bonding agent to enter magnetic pole seam by magnetic pole radial reaction force complete equipilibrium
Gap, the motive force disappearance into E, F area of space.Further, since the drainage of flow-guiding screen, bonding agent is along magnetic pole surfaces stream
Dynamic, so that the filling of the bonding agent of A, D, C, B area of space takes the lead in completing, this phenomenon causes " to be shorted " bonding agent continuation edge
The power that axially flows of inner wall gap of magnetic pole 43 and magnetic yoke 41.Therefore, driving force (pressure difference) source of mass flow disappears
It loses, continues to supplement so that being difficult to bonding agent in E, F area of space.Therefore, it is impossible to ensure in vacuum perfusion process later period magnetic
Pole and magnetic yoke wall gap can glued dose refill.
Experimental study also found, carrying out the technique of priming by vacuum in the state that rotor axial is placed vertically, there is also partial zones
Not the phenomenon that domain does not have bonding agent to flow through and forms hole or bubble.The embodiments of the present invention have carried out into one this phenomenon
Step is explored and analysis, please refers to Fig. 6 A and 6B.Fig. 6 A and 6B show forward's trace of two kinds of different moments bonding agents flowing.It is attached
Icon remembers that a1, a2, a3, a4 indicate that gum-injecting port, appended drawing reference b1, b2, b3 indicate bleeding point.As shown in Figure 6B, on bonding agent edge
Axially upwards flow during, the bonding agent of generally existing regional area axially from lower end flow up speed compared with
Slowly, the phenomenon that being outflanked by the bonding agent of adjacent two side areas, the left and right sides flowing forward outflank converge after formed one do not have
The region that bonding agent flows through.Obviously, such region exists, to bonding agent along Radial Flow, be sufficiently impregnated protection coating, fill out
Magnetize clearance between poles, filling magnetic pole and the flowing in magnetic yoke wall gap is worst intrinsic phenomenon.
