Abstract
The invention discloses a process for fixing resin impregnated adhesive tapes for a rotor. In the process, a rotor iron core, a rotary shaft and magnets are adopted, wherein the rotor iron core is formed by laminating a plurality of rotor blades; and a plurality of magnet grooves and non-magnetic grooves are formed on the circumferential surface of the rotor iron core. The process comprises the following steps of: firstly, putting the rotor iron core into a baking oven, and pre-heating the rotor iron core; secondly, uniformly coating glue on the surface of the rotor iron core, and inlaying the magnets into the magnet grooves; thirdly, winding the resin impregnated adhesive tape on the surface of each magnet, and winding an insulating adhesive tape outside the resin impregnated adhesive tape; and finally, putting the rotor iron core into the baking box again, baking the rotor iron core to make the resin impregnated adhesive tape tightly wrap on the surface of the magnet, and thus obtaining a finished product for fixing the resin impregnated adhesive tapes for the rotor. The process for fixing the resin impregnated adhesive tapes for the rotor has the advantages that: the thickness of each resin impregnated adhesive tape can be a fraction of that of metal; an interval between the adhesive tape and the magnet can be quite smaller than the interval between a metal annular ring and the magnet; the friction between the rotor and a stator is greatly reduced; the conduction conversion rate of a magnetic field of a motor is higher; and the rotor can be polished and shaped.
Description
Technical field:
The present invention relates to a kind of parts technique for fixing of servo permanent-magnet motor, what be specifically related to is a kind of technique for fixing rotor being coated and fixed with resin impregnated adhesive.
Background technology:
At present, normally used servo permanent-magnet motor, most of integral rotor structure that adopts, at the surface label magnet of rotor block, this mode structure is comparatively outmoded, and the poor stock utilization of manufacturability is lower, and easily cause in process of production waste of material, the intensity of rotor is low.
Conventionally technique for fixing is with the magnetic stripe on becket fixed rotor; do like this sheet metal to be worked into very thin very difficult; if the thick power output that can affect motor of sheet metal; sheet metal is in the time that motor moves, and the temperature of motor can reach 70 degree left and right conventionally, and at this moment sheet metal can because be heated, expansion etc. react; higher to motor-field conducting effect conversion ratio; and by the fixing magnetic sheet of metal, complex process, be difficult for outer through revising.
Summary of the invention:
In order to overcome the deficiency in prior art, the object of the invention is to be that a kind of technique is simple, magnetic conductivity good and the process for fixing resin impregnated adhesive tapes for rotor of energy-conserving and environment-protective.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of process for fixing resin impregnated adhesive tapes for rotor, comprise the rotor core being formed by stacking by multi-disc rotor blade, rotating shaft and magnet, on the periphery of described rotor core, be provided with a plurality of magnet grooves and magnet isolation tank, it is characterized in that, its technique is: first rotor core being put in baking oven in temperature is preheating one hour at 80 ℃, then in the surface uniform spreading glue of rotor core, be nested with magnet at magnet groove, be wound around resin impregnated adhesive at magnet surface again, after this at the outer insulating tape that is wound around of resin impregnated adhesive, prevent that resin impregnated adhesive from getting loose in not heating.Finally, rotor core is put into baking oven again and toast, baking temperature is 80 ℃, and baking time is 4～5 hours, makes resin impregnated adhesive sclerosis, is wrapped in closely the surface of magnet, thereby completes rotor resin impregnated adhesive consolidated article.
According to a kind of process for fixing resin impregnated adhesive tapes for rotor, it is characterized in that, described glue is EP-138 glue.
The present invention adopts above-mentioned technique, add man-hour 80 degree drying room baking 5 hours, resin impregnated adhesive thickness can reach the part of metal, with this adhesive tape fixed magnet, it is very small that the gap of adhesive tape and magnet can reach, and is much smaller than the gap of metal ring circle fixed magnet, greatly reduce the friction between rotor and heavy stone used as an anchor, higher to motor-field conducting effect conversion ratio, the shaping of can polishing after fixing with adhesive tape, it also has the following advantages:
(1), magnetic conductivity is good: the main component of resin impregnated adhesive is that glass fibre and ring are supported resin, is more beneficial to the conducting in the magnetic field of rotor;
(2), superiority:, can adsorb after being heated for solid in refrigeration, reduce taking of space, be convenient to install;
(3), processability: because its main component is resin and glass fibre, be convenient to the outer correction through size of rotor, reduce and turn the friction between stator and avoid because of the rotor diameter card machine causing that transfinites;
(4), the feature of environmental protection is good: its main component to operational environment without any chemical contamination.
Accompanying drawing explanation:
Further illustrate the present invention below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of rotor of the present invention resin impregnated adhesive consolidated article;
Fig. 2 is rotor cross section structure schematic diagram of the present invention.
Embodiment:
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Shown in figure 1 and Fig. 2:
A kind of process for fixing resin impregnated adhesive tapes for rotor of the present embodiment, wherein, rotor comprises the rotor core 101, rotating shaft 102 and the magnet 103 that are formed by stacking by multi-disc rotor blade, rotor core 101 is fixing by the rear cast aluminium of multi-disc rotor punching stack, and at interior reinforced hole and the lightening hole of being axially provided with of rotor core 101, in reinforced hole 109, penetrate reinforced pole or be cast into aluminium.
Its technique for fixing is: first rotor core 101 being put in baking oven in temperature is preheating one hour at 80 ℃, and then, in the surface uniform spreading glue of rotor core 101, what this glue adopted is EP-138 glue.After glue is smeared, magnet is nested in magnet groove, is wound around resin impregnated adhesive 106 on each magnet 103 surfaces, by fat impregnated adhesive 106, it is sealed, after this at the outer insulating tape that is wound around of resin impregnated adhesive 106, prevent that resin impregnated adhesive 106 from getting loose in not heating.
Finally, rotor core 101 is put into baking oven again and toast, baking temperature is 80 ℃, and baking time is 4～5 hours, and resin impregnated adhesive 106 is hardened, and is wrapped in closely the surface of magnet 103, thereby completes rotor resin impregnated adhesive consolidated article.
In addition, after fixing with resin impregnated adhesive 106, rotor core 101 shaping of can polishing.
The resin impregnated adhesive 106 of the present embodiment can be preserved at low temperatures, add and in 80 ℃ of baking ovens, toast 5 hours man-hour, its thickness can reach the part of metal, as shown in table 1, the test data that it is planted in the surperficial Gauss who uses before and after resin impregnated adhesive for rotor magnet:
The present embodiment is by this resin impregnated adhesive 106 fixed magnets 103, it is very small that the gap of resin impregnated adhesive 106 and magnet 103 can reach, gap than metal ring circle fixed magnet 103 is much smaller, greatly reduce the friction between rotor and heavy stone used as an anchor, higher to motor-field conducting effect conversion ratio.
