Description
Technical field
The utility model relates to the fixture of permanent magnet on the magneto, is specially a kind of magnetic pole box with positioning boss.
Background technology
Wind power generation is as a kind of clean reproducible energy, because its environmentally safe and its good economic benefit more and more are subject to the attention of countries in the world.In numerous wind-driven generator types, the characteristics that permanent-magnetic wind driven generator is lightweight because of it, volume is little, cost is low, efficient is high, maintenance is little become the representative of wind-driven generator of new generation.The magnetic pole box is the critical component on the magneto, and permanent magnet is had well fixedly protective effect.Existing magnetic pole box is generally laminated by the dove-tail form pole lamination and is welded, the dove-tail form pole lamination as shown in Figure 4, the dove-tail form pole lamination is complex-shaped, makes mould, the complex process of pole lamination.The box-packed timing of magnetic pole, the dovetail groove specification on the yoke is generally all larger, when the magnetic pole box is placed in the dovetail groove on the yoke, need to increases voussoir to each magnetic pole box and fix, and causes assembling to waste time and energy, and production efficiency is low.And the magnetic pole box radial dimension of this structure is larger, can cause yoke part stress excessive in high-speed permanent magnet motor, has unsafe factor.
Summary of the invention
The utility model provides a kind of magnetic pole box with positioning boss in order to solve the problem of existing magnetic pole box unreasonable structure.
The utility model is to adopt following technical scheme to realize: the magnetic pole box with positioning boss, some first pole laminations and some second pole lamination identical by shape are overrided to form, all have accordingly permanent magnet installing hole and the fixed lever installing hole that is positioned at permanent magnet installing hole below on the first pole lamination and the second pole lamination, also have bolt penetration hole on the second pole lamination with on the limit that yoke contacts, bolt penetration hole and fixed lever installing hole are communicated with, on the magnetic pole box that namely laminates the permanent magnet installing hole is arranged, the fixed lever installing hole that is positioned at permanent magnet installing hole below be positioned at face that yoke contacts on and the bolt penetration hole that communicates with the fixed lever installing hole, wherein there is the part of bolt penetration hole to be built up by the second pole lamination, remainder is built up by the first pole lamination, also be placed with the fixed lever that is processed with bolt hole in the fixed lever installing hole, the bolt hole position on the fixed lever and the bolt penetration hole position on the magnetic pole box are corresponding.By the fixed lever of bolt and insertion magnetic pole box, the magnetic pole box can be fixed on the yoke, and such pole lamination simple shape, and mould, the technique of making pole lamination are also simple.Because the magnetic pole box radial dimension that such pole lamination builds up is little, applicable to high-speed permanent magnet motor.
The above-mentioned magnetic pole box with positioning boss, the Bian Shangjun that contacts with yoke of the first pole lamination and the second pole lamination is extended with the location lug accordingly, be on the magnetic pole box with on the face that yoke contacts positioning boss to be arranged, positioning boss can insert the guide-localization groove that cooperates with it on the yoke, make things convenient for the installation of magnetic pole box, also so that the circumferential location of magnetic pole box is more accurate.
Above-mentioned magnetic pole box, scribble viscous coating on the first pole lamination and the second pole lamination, laminate the magnetic pole box eddy current loss that forms of welding by pole lamination large, if toughness coating on the pole lamination, the magnetic pole box eddy current loss that forms through heat-insulating pressurizing technique after laminating is little, and also need not weld.
Above-mentioned magnetic pole box, an end of described fixed lever has breach, and the part of the fixed lever of indentation, there is stretched out the fixed lever installing hole; When the magneto of relatively high power assembles the magnetic pole box, a plurality of magnetic pole boxes can be close to along rotor axial and be fixed on the yoke, the indentation, there of the fixed lever on the adjacent pole box fixed lever installing hole cooperates, and can prevent that the adjacent pole box is close to the pole lamination at place and flies out in the rotor high-speed rotary course.
The utility model so that the magnetic pole box to laminate operation simpler, shorten process cycle, save time 10%; Particularly in the box-packed timing of magnetic pole, the positioning boss on the magnetic pole box cooperates with location notch on the yoke, has increased assembly precision when saving the guide-localization frock, and has cancelled the voussoir of assembling usefulness, simplifies assembling process, saves frock cost 12%; Whole magnetic pole box radial dimension is less simultaneously, can satisfy high-speed permanent magnet motor design needs, uses more extensive.
