Description

本発明は、回転電機およびその製造方法に関するものである。   The present invention relates to a rotating electrical machine and a method for manufacturing the same.

従来の回転電機は、ステータをハウジングへ固定するため、ステータ取付面を有するハウジングとの焼き嵌めが行われる（例えば、特許文献１参照）。しかし、ステータとハウジングを焼き嵌めによって固定する場合、ハウジングの加熱が必要となり、加熱炉などの設備費やその管理費、設置スペースを要するため、製造コストが高くなる。また、焼き嵌めによりステータにハウジングからの応力が加わるため、ステータコアにひずみが生じトルク脈動の悪化やモータ効率の低下の要因となる。そこで、ステータの外径よりもわずかに大きな直径の内周面を有するハウジングにおいて、ステータをハウジングに配置し、ステータの外周面とハウジングの内周面の間に接着剤を注入して固定する方法がある（例えば、特許文献２参照）。   In a conventional rotating electrical machine, shrinkage fitting with a housing having a stator mounting surface is performed in order to fix the stator to the housing (see, for example, Patent Document 1). However, when the stator and the housing are fixed by shrink fitting, the housing needs to be heated, and equipment costs such as a heating furnace, its management costs, and installation space are required, which increases the manufacturing cost. Further, since stress from the housing is applied to the stator by shrink fitting, the stator core is distorted, which causes deterioration of torque pulsation and reduction of motor efficiency. Therefore, in a housing having an inner peripheral surface having a diameter slightly larger than the outer diameter of the stator, the stator is disposed in the housing, and an adhesive is injected and fixed between the outer peripheral surface of the stator and the inner peripheral surface of the housing. (See, for example, Patent Document 2).

しかしながら、上記の様に、ステータとハウジングを接着剤により固定する製造方法の場合、接着剤の使用量が多くなるため、製造コストが高くなるという問題があった。このため、製造コストの安価な回転電機およびその製造方法に対する要望が高まっていた。   However, as described above, in the manufacturing method in which the stator and the housing are fixed with the adhesive, the amount of the adhesive used is increased, which causes a problem that the manufacturing cost is increased. For this reason, the request with respect to the rotary electric machine with low manufacturing cost and its manufacturing method has increased.

実施の形態１．
以下、この発明の実施の形態を図に基づいて説明する。
図１は、本発明の実施の形態に係わる回転電機の正面模式図である。
図１に示すように、ステータ１０は、電磁鋼板などの金属シートからプレスで打ち抜かれたものを積層して形成されるステータコア１ａと、コイル巻線１ｂとを備える。このステータコア１ａは、その径方向外側に、ハウジング固定面１ｃを備える。また、ステータコア１ａを保持するハウジング２はこのハウジング固定面１ｃと対向するステータ取付面３を有するものである。 Embodiment 1 FIG.
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic front view of a rotating electrical machine according to an embodiment of the present invention.
As shown in FIG. 1, the stator 10 includes a stator core 1a formed by laminating metal sheets such as electromagnetic steel sheets punched out by a press, and a coil winding 1b. The stator core 1a includes a housing fixing surface 1c on the radially outer side. The housing 2 holding the stator core 1a has a stator mounting surface 3 facing the housing fixing surface 1c.

ステータ１０をハウジング２内に収納することにより、ステータ１０のハウジング固定面１ｃとハウジング２のステータ取付面３との間に、隙間４が形成される。また、ステータ１０の径方向内側には、軸５に回動可能に組み合わされたロータ６が配置される。 By accommodating the stator 10 in the housing 2, a gap 4 is formed between the housing fixing surface 1 c of the stator 10 and the stator mounting surface 3 of the housing 2. In addition, a rotor 6 that is rotatably combined with the shaft 5 is disposed inside the stator 10 in the radial direction.

図２に示すように、隙間４には接着層９が形成される。この接着層９は、粒体７と結合材８とを含む。この結合材８は粒体７と粒体７との間に浸透するとともに、ステータ１０のハウジング固定面１ｃ、ハウジング２のステータ取付面３、及び、粒体７を互いに接着により結合する。 FIG. 2 is a partial cross-sectional view showing a fixed portion between stator 10 and housing 2 of the rotary electric machine according to Embodiment 1 of the present invention.
As shown in FIG. 2, an adhesive layer 9 is formed in the gap 4. The adhesive layer 9 includes the particles 7 and the bonding material 8. The bonding material 8 penetrates between the granules 7 and bonds the housing fixing surface 1c of the stator 10, the stator mounting surface 3 of the housing 2, and the granules 7 together by adhesion.

ここで、接着層９の厚さをＧ、粒体７の平均径をＤとすると、それぞれの大きさの比率はＤ／Ｇ≦1／３程度となる。 Here, if the thickness of the adhesive layer 9 is G and the average diameter of the granules 7 is D, the ratio of the respective sizes is approximately D / G ≦ 1/3.

FIG. 3A shows an example of a substantially circular solid body, and FIG. 3B shows an example of a substantially I-shaped, L-shaped, and V-shaped solid body.
As for the type of the binder 8, an inorganic adhesive such as cement may be used in addition to an organic adhesive such as an acrylic adhesive.

次に、本願発明の実施の形態１にかかる回転電機の製造方法の一例について図１から図４を用いて説明する。かかる製造方法により得られる回転電機において用いられる粒体７は、ステータコア１ａと同じ材料、若しくは、コイル１ｂと同じ材料で形成される金属材料からなる粒体７が含まれる。
図４は、電磁鋼板などの金属シートをプレス加工することによりステータコア１ａを形成する際に生じる廃材１１や、コイル巻線１ｂの廃材１２を粒体７として用いる場合の模式図である。
この実施の形態においては、まず、図４に示すように、電磁鋼板などの金属シートをプレス加工することにより、ステータコア１ａの各層の一部を構成する略Ｔ字型の金属片を得る。図４は、略Ｔ字型の部分が打ち抜かれた後の残りの金属シートが示されており、略Ｔ字型の部分は図示されていない。得られた略Ｔ字型の金属片を円形に配置すると共に、紙面方向（図１の軸と平行な方向）に積層することにより、ステータコア１ａが形成される。 Next, an example of a method for manufacturing the rotating electrical machine according to the first embodiment of the present invention will be described with reference to FIGS. The granular material 7 used in the rotating electrical machine obtained by such a manufacturing method includes the granular material 7 made of the same material as the stator core 1a or the same material as the coil 1b.
FIG. 4 is a schematic diagram when the waste material 11 generated when the stator core 1a is formed by pressing a metal sheet such as an electromagnetic steel sheet or the waste material 12 of the coil winding 1b is used as the granular material 7.
In this embodiment, first, as shown in FIG. 4, a substantially T-shaped metal piece constituting a part of each layer of the stator core 1 a is obtained by pressing a metal sheet such as an electromagnetic steel sheet. FIG. 4 shows the remaining metal sheet after the substantially T-shaped part is punched out, and the substantially T-shaped part is not shown. The obtained substantially T-shaped metal pieces are arranged in a circle and stacked in the paper surface direction (a direction parallel to the axis in FIG. 1) to form the stator core 1a.

次に、このようにして得られたステータコア１ａにコイル１ｂを巻くことにより、ステータ１０が形成される。このようにして得られたステータ１０をハウジング２に収納することにより、ステータ１０のハウジング固定面１ｃとハウジング２のステータ取付面３との間に、隙間４が形成される。 Next, the stator 10 is formed by winding the coil 1b around the stator core 1a thus obtained. By accommodating the stator 10 thus obtained in the housing 2, a gap 4 is formed between the housing fixing surface 1 c of the stator 10 and the stator mounting surface 3 of the housing 2.

続いてこの隙間４に複数の粒体７と結合材８とを入れる。ここで、この粒体７は、図４において、プレス加工を行った際に略Ｔ字型の金属片が打ち抜かれることにより残ることとなった金属シート（図４で斜線で示される部分）から得られる廃材１１や、コイル巻き線の廃材１２を細かく破砕することにより得られる。このような廃材１１や１２を粒体７に用いた場合、粒体７の平均径Ｄの下限値は、コア積層板（金属シート）厚さ、コイル巻線（マグネットワイヤ）の線径などから、約０．１ｍｍとなる。   Subsequently, a plurality of granules 7 and a binder 8 are put in the gap 4. Here, the granular material 7 is obtained from the metal sheet (portion indicated by hatching in FIG. 4) that is left by punching out a substantially T-shaped metal piece in the press processing in FIG. 4. It is obtained by finely crushing the obtained waste material 11 and the coil-wound waste material 12. When such waste materials 11 and 12 are used for the granules 7, the lower limit value of the average diameter D of the granules 7 is based on the thickness of the core laminate (metal sheet), the wire diameter of the coil winding (magnet wire), and the like. About 0.1 mm.

結合材８が、適度な過熱、冷却、あるいは時間経過により、固まることにより、ステータ１０のハウジング固定面１ｃ、ハウジング２のステータ取付面３、及び、粒体７とが互いに接着される。このようにして、接着層９が形成され、ステータ１０がハウジング２に接着により固定される。 When the bonding material 8 is hardened by appropriate overheating, cooling, or passage of time, the housing fixing surface 1c of the stator 10, the stator mounting surface 3 of the housing 2, and the particles 7 are bonded to each other. In this way, the adhesive layer 9 is formed, and the stator 10 is fixed to the housing 2 by adhesion.

従来技術においては、接着強度を確保するために、接着層の厚さを０．１ｍｍ以下、好ましくは０．０３〜０．１ｍｍ程度に設定することが望ましかった。しかし、例えば鋳造でハウジング２を製造した場合、鋳抜き後のハウジング２の寸法公差は±２〜１０ｍｍ程度である。このため、ハウジング２の成形後にステータ取付面３の追加工を行わなわなければ、接着層が０．１ｍｍより厚くなることがある。
このため接着層が厚くなる場合があり、接着強度が低下するとの問題があった。
本実施の形態によれば、ステータ１０のハウジング固定面１ｃとハウジング２のステータ取付面３の隙間４に、粒体７を充填し、結合材８によってステータ１０を固定するため、接着層９が厚くなる場合においても、高強度にステータ１０を固定することができる。 In the prior art, in order to ensure the adhesive strength, it has been desired to set the thickness of the adhesive layer to 0.1 mm or less, preferably about 0.03 to 0.1 mm. However, when the housing 2 is manufactured by casting, for example, the dimensional tolerance of the housing 2 after casting is about ± 2 to 10 mm. For this reason, the adhesive layer may become thicker than 0.1 mm unless the stator mounting surface 3 is additionally processed after the housing 2 is molded.
For this reason, the adhesive layer may be thick, and there is a problem that the adhesive strength is lowered.
According to the present embodiment, the gap 4 between the housing fixing surface 1c of the stator 10 and the stator mounting surface 3 of the housing 2 is filled with the granules 7, and the stator 10 is fixed by the bonding material 8. Even when the thickness is increased, the stator 10 can be fixed with high strength.

また、結合材８の使用量を低減することが可能となり、製造コストの抑制を図ることができる。
さらに、粒体７に鉄や銅などの金属材料を用いた場合、接着層９の放熱性や磁気特性が向上し、製品の特性向上を図ることができる。 Moreover, it becomes possible to reduce the usage-amount of the coupling | bonding material 8, and can aim at suppression of manufacturing cost.
Furthermore, when a metal material such as iron or copper is used for the particles 7, the heat dissipation and magnetic characteristics of the adhesive layer 9 are improved, and the characteristics of the product can be improved.

加えて、この実施の形態では、ステータ１０のハウジング固定面１ｃとハウジング２のステータ取付面３の隙間４に入れる粒体７に、ステータコア１ａを電磁鋼板などの金属シートからプレス加工して形成した際に生じる廃材１１や、コイル巻線１ｂの廃材１２を用いたので、廃材の再利用が可能となり、工場内での材料歩留まりが良くなる。 In addition, in this embodiment, the stator core 1a is formed by pressing from a metal sheet such as a magnetic steel sheet in the granule 7 to be inserted into the gap 4 between the housing fixing surface 1c of the stator 10 and the stator mounting surface 3 of the housing 2. Since the waste material 11 generated at the time and the waste material 12 of the coil winding 1b are used, the waste material can be reused, and the material yield in the factory is improved.

尚、図２に示すように、先に粒体７を隙間４にいれておき、その後、結合材８を注入することが可能である。このように、粒体７と結合材８とを別々に隙間４に入れることができる。あるいは、粒体７と結合材８とをあらかじめ混合したものを隙間４に入れても良い。いずれの場合もこの発明に含まれる。 In addition, as shown in FIG. 2, it is possible to put the granule 7 in the gap 4 first and then inject the binder 8. Thus, the granule 7 and the binder 8 can be put into the gap 4 separately. Or you may put what mixed the granule 7 and the binder 8 previously in the clearance gap 4. FIG. Either case is included in the present invention.

また、プレス加工や廃材の破砕工程と、隙間４に接着層９を形成する工程との間にはタイムラグがあるのが通常である。このため、ある特定の一回のプレス加工で得られた略Ｔ字型の金属片と、その特定のプレス加工時に生じた廃材である粒体７とが同じ１つの回転電機の製造に用いられる場合は少ないと考えられる。しかし、このような場合も本願発明に含まれる。また、当然、あるロットで製造された略Ｔ字型の金属片と、この金属片とは異なるロット（異なる回のプレス加工）で得られた廃材とが１つの回転電機の製造に用いられる場合も本願発明に含まれることは言うまでもない。 Further, there is usually a time lag between the pressing process and the waste material crushing process and the process of forming the adhesive layer 9 in the gap 4. For this reason, the substantially T-shaped metal piece obtained by one specific press work and the granular material 7 which is the waste material produced at the time of the specific press work are used for manufacturing the same single rotating electric machine. There are few cases. However, such a case is also included in the present invention. Naturally, a case where a substantially T-shaped metal piece manufactured in a certain lot and waste material obtained in a lot different from the metal piece (pressing different times) are used for manufacturing one rotating electrical machine. Needless to say, this is also included in the present invention.

また、隙間４に入れられる粒体７の全てが、回転電機を製造する際に生じる廃材で構成される場合の他、隙間４に入れられる粒体７の一部がそのような廃材で構成されても良い。   Further, in addition to the case where all of the granules 7 put in the gap 4 are made of waste materials generated when the rotating electrical machine is manufactured, a part of the granules 7 put in the gap 4 is made of such waste materials. May be.
