Description
Technical field
The invention belongs to the technical fields of electromechanical structure, and in particular to a kind of insulation system of machine winding and its preparation side
Method.
Background technique
Whether the insulation of machine winding and motor leak electricity and the turn-to-turn of winding, and short circuit is inseparable between phase and phase.Electricity
The reliability of machine winding insulation is the key that guarantee motor service life, even a little neglecting in manufacturing process, can also make
At the decline of insulation quality, or even cause insulation breakdown, causes motor damage.Traditional stator core insulation way majority is system
There is copper wire winding after performing insulation sleeve, on insulation sleeve, insulation sleeve is covered on stator core by way of the fitting of front and back, winding
It is separated with stator core by insulation sleeve, but this fitting mode has fitting gap, and this gap is exactly that one kind is deposited
Weak location, it is easy to insulation breakdown is caused to motor.
Summary of the invention
For above-mentioned machine winding insulation system there are fitting gap, which is easy to cause insulation breakdown to motor
The problem of, the present invention provides a kind of insulation system of machine winding and preparation method thereof in no fitting gap.
In order to solve the above technical problems, the technical solution adopted by the present invention is that：A kind of insulation system of machine winding, including
Stator core and insulation sleeve, the stator core are integral type pied geometries；The stator core includes multiple " work " words
Shape unit stator；The insulation sleeve includes the unit insulation sleeve in gap between multiple embedded unit stators, and the unit is exhausted
Edge covers integrated injection molding.
Further：In the insulation system of above-mentioned machine winding, the unit insulation sleeve be in lead to column structure, and
There is outer edge at cylindricality both ends.The outer edge is equipped with the buckle mouth for facilitating copper wire to lay out.During the unit insulation sleeve is
Logical flat column structure, the outer edge are also square structure, and the buckle mouth is symmetricly set on outer edge.
The present invention also provides the preparation method of the insulation system of above-mentioned machine winding, step is：A, stator core uses
Self-clinching punching shaping；B, the stator core of step A is fixed in injection mold, is molded and is insulated using injection molding machine high temperature and pressure
Set；The insulation sleeve material weight percentage composition is the PA of 68%-72%, and surplus is glass fibre.Between step A and B
Further include injection mold is pressed stator core, oil removing, exhaust and injection moulding process.Preparation process is simple and easy.PA nylon is (poly-
Amide) there is good comprehensive performance, including mechanical property, heat resistance, wear resistance, chemical resistance and self-lubrication,
And coefficient of friction is low, there is certain anti-flammability, and it is easy to process, with glass fibre and other filler filling enhancing modifieds, raising property
It can and expand application range and glass fibre be added in nylon, can achieve the effect of plasticising, that is, so-called plasticizer, it can
To enhance the Physical Constants of nylon.30% glass fibre is added in PA, it is the mechanical property of PA, dimensional stability, heat resistance, resistance to
Ageing properties are significantly improved, and endurance life is non-reinforced 2.5 times.The moulding process of glass fiber reinforcement PA and non-reinforced
When it is roughly the same, but mobility can reduce, so injection pressure and injection speed will properly increase, material temperature and Mo Wen will be appropriate
Raising.Since meeting streamwise is orientated glass in injection moulding process, cause mechanical property and shrinking percentage in the orientation direction
Enhancing, leads to product deformation warpage, and therefore, when mold design, will mould be rationally can be improved in the position of cast gate, shape in technique
The temperature of tool, the ratio that glass is added is bigger, bigger to the abrasion of the plasticizing element of injection molding machine, the mainly abrasion of screw rod.
Compared with prior art, the stator core is integral type pied geometry；The stator core includes multiple
I-shaped unit stator；The insulation sleeve includes the unit insulation sleeve in gap between multiple embedded unit stators, described
Unit insulation sleeve integrated injection molding.So that together with the insulation sleeve injection molding seamless with stator core, so that machine winding coil
There is no gap between stator punching iron core, greatly improve the insulation performance and security performance of motor, can also according to difference around
Insulation sleeve is fabricated to different shapes by line mode of connection, is facilitated winding outlet and wiring, is greatly improved production efficiency.Pass through spy
The insulation sleeve buckle mouth very designed can hang over winding the end of a thread according to the mode of connection of different requirements and fasten above buckle mouth,
When wiring in sequence the end of a thread welding can, will not be excessive because of the end of a thread and lead to wrong line.Insulation sleeve can be
The buckle mouth of copper wire the design various sizes and shape of different size, can be very good protective winding copper wire and is not damaged and causes
Winding short-circuit between conductors.
Detailed description of the invention
Fig. 1 is the schematic diagram of machine winding insulation system of the present invention；
Fig. 2 is the structure diagram of iron core of the present invention；
Fig. 3 is the structure diagram of invention unit insulation sleeve；
Wherein, 1 stator core, 2 insulation sleeves, 3 outer edges, 4 buckle mouths, 5 unit stators, 6 unit insulation sleeves.
Specific embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with specific embodiments and drawings to structure of the invention original
Reason is further described in detail：
