Abstract
The utility model provides a magnetic steel of a generator, belonging to the technical field of machinery. The utility model solves to problem that the conventional magnetic steel is inconvenient to process, wasting the materials. The magnetic steel of the generator comprises a plate-shaped magnetic body, wherein the body has a first direct side edge and a second direct side edge on the left side and the right side respectively; the body has a first arc side edge and a second arc side edge on the upper side and the lower side, the second arc side edge being arranged in the same direction with the first arc side edge; an upper end of the first direct side edge is connected with one end of the first arc side edge, an upper end of the second direct side edge is connected with the other end of the first arc side edge, a lower end of the first direct side edge is connected with one end of the second arc side edge, and a lower end of the second direct side edge is connected with the other end of the second arc side edge; the first arc side edge has an arc radius equal to that of the second arc side edge; and the circle center of the first arc side edge and the circle center of the second arc side edge are in a connecting line of a midpoint of the first arc side edge and a midpoint of the second arc side edge. The magnetic steel of the generator is convenient to process and reasonable in structure.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of magnet steel of generator.
Background technology
The magnet steel of existing permanent magnet generator is screwed in the rotating shaft surface, be drilled with screwed hole to facilitate the installation of screw on the rotating shaft surface, cause the rotating shaft surface crackle to occur, course of work shaft vibrates for a long time, easily fatigue break, magnet steel is also frangible, causes its useful life short, and concentricity is relatively poor.
problem for above-mentioned rotating shaft existence, the applicant has invented a kind of rotor structure of permanent magnet generator, it comprises rotating shaft, be set in successively the pad in this rotating shaft, head plate one, magnet steel and head plate two, pad is fixedly installed in rotating shaft, head plate one is resisted against on this pad, magnet steel is resisted against on head plate one, head plate two is resisted against on this magnet steel, and then by a locking nut, head plate two is locked, have some fixed cells that are set in rotating shaft between head plate one and head plate two, have two shrinkage pools that relatively arrange on fixed cell, magnet steel is embedded in this shrinkage pool.Consider that said structure need to be circumferentially fixing with rotating shaft, spline shaft structure is arranged in rotating shaft.There is no screw in this rotor structure, can not crack, because fixed cell is enclosed in the inside with magnet steel, even the overall structure of the cracked rotor of magnet steel is unaffected.Two arc limits of common magnet steel arrange with one heart, and the arc radius does not wait, and under the condition of same magnetic intensity, needed material is more, and its structural design is unreasonable.Therefore, need a kind of rational permanent magnet magnet steel of design.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of magnet steel of generator of reasonable in design.
The purpose of this utility model can realize by following technical proposal:
a kind of magnet steel of generator, comprise magnetic body in the form of sheets, it is characterized in that, the left and right sides of described body is respectively the first straight sided and the second straight sided, the second arc side that the both sides up and down of described body are respectively the first arc side and arrange in the same way with the first arc side, the upper end of described the first straight sided is connected with an end of the first arc side, the upper end of the second straight sided is connected with the other end of the first arc side, the lower end of described the first straight sided is connected with an end of the second arc side, the lower end of the second straight sided is connected with the other end of the second arc side, described the first arc side equates with the arc radius of the second arc side, the center of circle of the center of circle of the first arc side and the second arc side is positioned on the line of both mid points.
In the magnet steel of above-mentioned a kind of generator, the even thickness of described body.
Compared with prior art, the magnet steel of this generator has the following advantages:
Because the arc radius of the first arc side with the second arc side equates, easy to process, easily make, increased the area of body, after body magnetized, magnetic was stronger.
Description of drawings
Fig. 1 is the structural representation of a kind of preferred embodiment of providing of the utility model.
Fig. 2 is the cutaway view at A-A place in Fig. 1.
In figure, 1, body; 2, the first straight sided; 3, the second straight sided; 4, the first arc side; 5, the second arc side.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, the magnet steel of this generator, comprise magnetic body 1 in the form of sheets, the left and right sides of body 1 is respectively the first straight sided 2 and the second straight sided 3, the second arc side 5 that the both sides up and down of body 1 are respectively the first arc side 4 and arrange in the same way with the first arc side 4.As shown in Figure 1, the upper end of this first straight sided 2 is connected with an end of the first arc side 4, the upper end of the second straight sided 3 is connected with the other end of the first arc side 4, the lower end of the first straight sided 2 is connected with an end of the second arc side 5, and the lower end of the second straight sided 3 is connected with the other end of the second arc side 5.In the present embodiment, as shown in Figure 2, the even thickness of body 1.
As shown in Figure 1, the first arc side 4 equates with the arc radius of the second arc side 5, and the center of circle of the center of circle of the first arc side 4 and the second arc side 5 is positioned on the line of both mid points.In the present embodiment, easy to process because the arc radius of the first arc side 4 with the second arc side 5 equates, easily make, increased the area of body 1, after body 1 magnetized, magnetic was stronger.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more used 1, body; 2, the first straight sided; 3, the second straight sided; 4, the first arc side; 5, the term such as second arc side, but do not get rid of the possibility of using other term.Using these terms is only in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
