Description
Technical field
The utility model belongs to bearing of wind power generator insulating Design, relates to a kind of shaft current of avoiding to the impact in bearing useful life, reduces the insulating end cover structure of the wind-driven generator of manufacturing cost simultaneously.
Background technology
Due to stator and rotor air gap uneven, the reasons such as stator silicon steel sheet seam, axle center and magnetic field center are inconsistent, rotor is inevitably rotated in the magnetic field of non complete symmetry, cause rotating shaft produces shaft voltage, when it runs up to a certain degree, can bearing film be punctured and form shaft current.When shaft current is by bearing roller and inner ring, form electric discharge, damage bearing.Therefore, insulation bearing is selected when designing.Adopt insulation bearing to be the effective measures preventing shaft current, but owing to limiting by the source of goods, grow, price, is difficult to the production cycle ensureing motor insulation bearing procurement cycle.
Utility model content
The purpose of this utility model is the insulating end cover structure providing a kind of wind-driven generator, compact conformation, and insulation effect is desirable, is convenient to processing and manufacturing.Replace insulation bearing with it, can procurement cycle be shortened, reduce production cost.
The technical solution of the utility model is as follows:
An insulating end cover structure for wind-driven generator, comprises insulating sleeve, insulating case, securing member, insulation board and end cap; End cap is fixed on insulating sleeve by securing member; Insulating case is arranged between insulating sleeve and securing member; Insulation board is arranged between insulating sleeve and end cap; Insulating sleeve, insulating case, insulation board and end cap connect by securing member.
Its further technical scheme is: described insulating sleeve comprises axle sleeve and covers the insulating barrier on the contact-making surface between axle sleeve and end cap.The material of described insulating barrier is insulating tape, and colligation is on axle sleeve; The surface that described axle sleeve contacts with insulating barrier is zigzag, ring fills or helical form.Or the material of described insulating barrier is epoxy resin insulating material or ceramic insulating material.
And its further technical scheme is: the material of described insulating case and insulation board is epoxy resin insulating material.
And its further technical scheme is: end cap and casing are fixedly linked, and bearing is arranged in insulating sleeve.
Advantageous Effects of the present utility model is:
Metalwork is separated by insulating sleeve, insulation board, insulating case by the utility model, blocks electric current and reaches insulation object.Insulating end cover structure is simple, easily manufactured, can replace expensive insulation bearing by plain bearing, reduces the cost of motor, shortens the production cycle.
Advantage of the present utility model provides in the description of embodiment part below, and part will become obvious from the following description, or be recognized by practice of the present utility model.

In Fig. 2: 1-insulating sleeve, 2-insulating case, 3-securing member, 4-insulation board, 5-end cap.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Assembling effect of the present utility model as shown in Figure 2, is made up of insulating sleeve 1, insulating case 2, securing member 3, insulation board 4, end cap 5.
Insulating sleeve 1 mainly comprises axle sleeve 01 as shown in Figure 1 and insulating barrier 02.Insulating barrier 02 material is a kind of insulating tape, and this insulating tape colligation is on axle sleeve 01.For ensureing that insulating tape colligation is firm, axle sleeve 01 surface (with the contact-making surface of insulating barrier 02) being designed to zigzag, ring fills or helical form.This insulating barrier 02 has good mechanical performance and impact resistance.
Insulating case 2, insulation board 4 can be arbitrary insulating material.Preferred insulating case 2, insulation board 4 are made up of epoxy resin.Epoxy resin body after solidification is the superior isolation material with excellent mechanical property, high dielectric property, resistance to surface leakage, resistance to electric arc.
Insulating barrier 02 material is not limited to insulating tape, adopts the material of the good insulation preformances such as epoxy resin insulating material, pottery.Insulating case 2, insulation board 4 material are also not limited to epoxy resin insulating material, and other have insulating properties, the material of impact resistance.
Mounting means of the present utility model: end cap 5 is fixed on insulating sleeve 1 by securing member 3; Insulating case 2 is arranged between insulating sleeve 1 and securing member 3, and insulation board 4 is arranged between insulating sleeve 1 and end cap 5; Insulating sleeve 1, insulating case 2, insulation board 4, end cap 5 connect by securing member 3.When using the utility model, end cap 5 and casing are fixedly linked, and bearing is arranged in insulating sleeve 1.
As can be seen from Figure 2, the contact-making surface between insulating sleeve 1 and end cap 5 utilizes insulating barrier 02, insulating case 2, insulation board 4 reach insulation object, prevent electric current from transmitting between insulating sleeve 1 and end cap 5, and then achieve the object intercepting shaft current.
Above-described is only preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate under the prerequisite not departing from basic conception of the present utility model, all should think and be included within protection range of the present utility model.
