Abstract
The utility model relates to a motor part and specifically relates to a high strength glass fiber cloth drawing groove wedge. The high strength glass fiber cloth drawing groove wedge is characterized in that front and back surface layers are alkali-free glass cloth, alkali-free glass cloth and alkali-free glass fiber are in staggered arrangement on other layers to form a whole multi-layer structure one layer of alkali-free glass cloth by one layer of alkali-free glass fiber, the alkali-free glass cloth is 85 grams per one square meter or 60 grams per one square meter, a count of the alkali-free glass fiber is 4800tax or 2400tax or 1200tax, both are dipped with adhesives, and each layer of the alkali-free glass cloth and the alkali-free glass fiber are molded by extruding and bonding. The high strength glass fiber cloth drawing groove wedge has great cleavage strength.
Description
Technical field
The utility model relates to a kind of motor component, specifically a kind of high strength glass fiber drawing groove wedge.
Background technology
Motor is when normal operation, and the slot wedge of fixed coil, especially rotor slot wedge will bear huge centrifugal force under electromagnetic force.In addition, owing to require slot wedge and grooved to closely cooperate, so not only require the size of slot wedge accurate, also require slot wedge to have higher mechanical strength, especially time cut intensity has higher requirement.
Existing drawing groove wedge is general to adopt single glass fibre to make, and it is applicable to use in rotor in the stator of motor, because can be subject to the double action of electromagnetic force and centrifugal force, its mechanical strength can't satisfy actual operation requirements.
The utility model content
Technical problem to be solved in the utility model is to overcome shortcoming and defect of the prior art and provide a kind of split resistance good high strength glass fiber drawing groove wedge.
The technical scheme in the invention for solving the above technical problem is: this extraction slot wedge for high intensity glass fiber cloth, it is characterized in that: its positive and negative top layer is alkali-free glass cloth, alkali-free glass cloth and alkali-free glass fibre interval arrange in all the other each layers, the whole sandwich construction that forms layer of glass cloth one deck alkali-free glass fibre, its Gram Mass of alkali-free glass cloth is 85g/m2 or 60g/m2, its number of alkali-free glass fibre is 4800tax or 2400tax or 1200tax, both all flood and contain adhesive, the extrusion bonded moulding of each layer alkali-free glass cloth and alkali-free glass fibre.
Alkali-free glass fibre marshalling described in the utility model is bonded on the alkali-free glass fiber cloth.
The utility model compared with prior art has following beneficial effect: the utility model adopts the alkali-free glass layer of cloth and the alkali-free glass fibre layer is gluing is composited, owing to introduced glass fabric and glass fiber yarn composite reinforcing material makes the heat resisting temperature of slot wedge reach H level (〉=180 ℃), bending strength rises to 〉=500Mpa, split resistance rises to 〉=3500N/10mm, thereby slot wedge can be used for large high-voltage motor, on track traffic (high ferro, motor-car etc.) motor and the wind-driven generator, satisfied motor technology and improved the requirements at the higher level that slot wedge is insulated.

Embodiment
Referring to Fig. 1 ~ Fig. 2, its positive and negative top layer of high strength glass fiber drawing groove wedge I described in the utility model is alkali-free glass cloth 1, alkali-free glass cloth 1 arranges with alkali-free glass fibre 2 intervals in all the other each layers, the whole sandwich construction that forms layer of glass cloth 1 one deck alkali-free glass fibre 2, alkali-free glass cloth 1 its Gram Mass is 85g/m
2Or 60g/m
2, alkali-free glass fibre 2 its numbers are 4800tax or 2400tax or 1200tax, and both all flood and contain adhesive, and alkali-free glass fibre 2 marshallings are bonded on the alkali-free glass fiber cloth 1, each layer alkali-free glass cloth 1 and alkali-free glass fibre 2 extrusion bonded moulding.The number of plies of the alkali-free glass cloth 1 that uses, the number of share of stock of alkali-free glass fibre 2 arranges by the requirement of product actual (real) thickness, and dimensions is adjustable.
Above embodiment has made comparatively detailed description to the utility model, but these descriptions are not to be to restriction of the present utility model; Protection range of the present utility model comprises those to those skilled in the art apparent conversion or alternative and remodeling.Allly conceive equivalence or the simple change that described structure, feature and principle are done according to the utility model patent, be included in the protection range of the utility model patent.
Claims (2)
