Abstract
The utility model relates to a fixing device for a permanent magnet of a permanent magnetic motor. The fixing device comprises a magnet yoke, a permanent magnet and a permanent magnet fixing assembly. The fixing device is characterized in that the permanent magnet fixing assembly is formed by splicing multiple arc permanent magnet isolation units, the permanent magnet isolation units mainly comprise arc positioning sheets, arc connection sheets and isolation boards, one end of each isolation board is connected with an axial section of the corresponding arc positioning sheet, an outer side face of the other end of the isolation board is connected with an inner circumferential face of the corresponding arc connection sheet, the arc connection sheets, the arc positioning sheets and every two adjacent isolation boards form an isolation chamber, the permanent magnet is embedded in the isolation chamber, the arc connection sheet and the magnet yoke are provided with connection holes, and the connection holes are internally equipped with thread connection members. The fixing device for the permanent magnet of the permanent magnetic motor can be used without special mechanical processing, and processing difficulty can be reduced; through the permanent magnet isolation units, constraint of the permanent magnet in the circumference direction can be realized, and problems of dislocation in the circumference direction and shedding can be settled.
Description
Technical field
The utility model belongs to magneto manufacturing technology field, particularly relates to the fixture of a kind of magneto permanent magnet.
Background technology
As everyone knows, magneto has advantages of energy-efficient, be widely used in industry-by-industry, but the permanent magnet of magneto easily demagnetizes, during especially at high temperature with motor frequent starting, so in the time that permanent magnet has influence on the performance of motor, just must change, so just the fixed form of permanent magnet be had relatively high expectations.
At present; the permanent magnet of magneto is fixing generally all adopts the modes such as built-in plug-in type or surface-type bonding, connector connection; these structures all have shortcoming in various degree to the surface protection of permanent magnet; and after damaging, permanent magnet is difficult for changing; particularly built-in plug in construction; change a permanent magnet, often need to expend larger man power and material.In addition, along with improving constantly of magneto power, the applied environment of magneto is also changing, therefore to the surfacecti proteon of permanent-magnet magnetic and fixing more and more important.Therefore be necessary the fixed form of existing permanent magnet to improve.
The material of fixed permanent magnet can adopt various non-magnet materials, and the non-magnetic plastics of general employing are made at present.But intensity is lower after injection molding, in assembling process, easily damage, easily distortion, dimensional accuracy is not easy to guarantee, particularly after motor rotation temperature raises.
Summary of the invention
One is simple in structure, difficulty of processing is processed in reduction, improve installation and maintenance efficiency for the technical problem existing in solution known technology provides for the utility model, the magneto the reducing costs fixture of permanent magnet.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:
The fixture of permanent magnet for a kind of magneto, comprise yoke, permanent magnet and permanent magnet fixation kit, it is characterized in that: described permanent magnet fixation kit is assembled by several permanent magnet isolated locations, and the inner periphery of described yoke is provided with the step for placing above-mentioned permanent magnet fixation kit; Above-mentioned permanent magnet isolated location is formed by the non-metallic magnetic material integrally casting of leading, and permanent magnet isolated location is arc-shaped structure, and its radian is to carry out decile according to yoke inner peripheral surface; Described permanent magnet isolated location mainly comprise arc spacer, arc brace and be arranged on arc spacer and arc brace between demarcation strip; Described demarcation strip one end connects on the axial section of arc spacer, and concordant with the excircle of arc spacer; The lateral surface of the other end of described demarcation strip connects the inner peripheral surface of arc brace sheet; Above-mentioned arc brace, arc spacer and two adjacent demarcation strips have formed separate cavities, in separate cavities, place setting-in permanent magnet, described permanent magnet is adsorbed in yoke, on above-mentioned arc brace, be in axial direction provided with connecting hole, on the outer face of yoke be provided with the connecting hole mating with connecting hole, equipped threaded connectors in two corresponding connecting holes.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, adopt according to the permanent magnet isolated location of any decile of circumference and carry out permanent magnet to be fixed, permanent magnet isolated location adopts non-ly leads metallic magnetic material casting and forms, non-magnetic Strength of Metallic Materials is high, not yielding, after casting, easily obtain higher dimensional accuracy, do not need special machining to use, thereby reduce difficulty of processing, reduced processing cost; Constraint by permanent magnet isolated location to permanent magnet circumferencial direction, and then avoided the generation of problems such as misplacing, come off at circumferencial direction; In addition, the utility model is all comparatively convenient and swift in the time of maintenance and installation, has alleviated operating personnel's labour intensity, has saved maintenance cost simultaneously.
