本発明は、車輌用交流発電機における、界磁鉄心のコス
ト低減と、生産効率の向上方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for reducing the cost of a field core and improving production efficiency in a vehicle alternator.
従来の装置は、特開昭５７−１１６５６９号公報に記載
のように、２ピース構造の界磁鉄心を有する交流発電機
について、ボビンの固定方法については、記述されてい
ない。In the conventional device, as described in Japanese Patent Laid-Open No. 57-116569, there is no description of a bobbin fixing method for an alternating current generator having a two-piece field core.
上記従来技術は、２ピース構造の界磁鉄心に組み合わせ
るボビンの種類や方法については配慮されていない。一
般的に２ピース構造の界磁鉄心には紙製のボビンを接着
剤により固定する方法を行なっている。The above-mentioned conventional technology does not consider the type or method of bobbins to be combined with the two-piece field core. Generally, a paper bobbin is fixed to a two-piece field core using an adhesive.
本発明は、２ピース構造の界磁鉄心に、樹脂製ボビンを
組み合わせることを目的としており、さらに、ボビンの
接着工程を省略することを目的とする。The present invention aims to combine a resin bobbin with a field core having a two-piece structure, and further aims to omit the process of bonding the bobbin.
上記目的を達成するために、円筒の金属からなるスペー
サを使用し、ボビンを、前記スペーサに界磁巻線により
巻き付は固定させることにより、鉄心との接着が困難な
樹脂製ボビンを使用できる様にしたものである。In order to achieve the above object, a cylindrical metal spacer is used and the bobbin is fixedly wound around the spacer by a field winding, thereby making it possible to use a resin bobbin that is difficult to bond to the iron core. It was made in a similar manner.
さらに、前記スペーサを、界磁鉄心へ圧入して組み立て
ることにより、前記スペーサと、前記ボビンは固定され
動くことはなくなるため、固定用の接着剤を不要にする
ものである。Furthermore, by assembling the spacer by press-fitting it into the field core, the spacer and the bobbin are fixed and do not move, thereby eliminating the need for a fixing adhesive.
円筒の金属からなるスペーサーに樹脂製ボビンは巻き付
は固定されており、更に、界磁鉄心に、前記スペーサは
圧入固定される構造となる。The resin bobbin is wound and fixed around a cylindrical metal spacer, and the spacer is press-fitted and fixed to the field core.
このため、樹脂製ボビンは、接着剤による固定をしなく
とも、動いたり、ずれたりの不具合は発生しない。Therefore, the resin bobbin does not move or shift even if it is not fixed with adhesive.
以下、本発明の一実施例を第１図により説明する。第１

磁鉄心１を圧入により固定しているシャフトである。An embodiment of the present invention will be described below with reference to FIG. 1st
The figure is a cross-sectional view of a two-piece field core of an alternator. 1 is a field core, two of which form a set. 2
3 is a bobbin made of nylon resin, and 3 is a field winding wound around the bobbin 2. 4 is the field core 1
A spacer 5, which is a cylindrical iron material located between the bobbin 2 and the bobbin 2 to prevent the bobbin 2 from moving, is a shaft to which the field core 1 is fixed by press fitting.

である。Here, for comparison, a current two-piece structure field core will be described. In the current two-piece field core, there is no spacer 4, and a paper bobbin is directly bonded to the field core 1. It is impossible to change from a nylon bobbin to a nylon bobbin because there is no adhesive that can fix the iron core and nylon.
以上の点を踏まえ、次に本発明品の組み立て方について

界磁鉄心１の間は固定され、ずれることはない。Based on the above points, next, a method of assembling the product of the present invention will be explained. First, as shown in FIGS. 2 and 3, the spacer 4 is a cylindrical iron material with a taper. Spacer 4
If the nylon bobbin 2 is set on top of the bobbin 2 and the field winding 3 is wound thereon, the bobbin 2 and the spacer 4 are crimped and fixed, so they will not shift. In addition, the previously mentioned fixed
Integrated bobbin 2. The field winding 3 and spacer 4 are
Since it is press-fitted into the boss part of the field core 1, the spacer 4 and
The space between the field cores 1 is fixed and does not shift.
本実施例によれば、ナイロンボビンは、２ピースの界磁
鉄心構造においても、使用可能となり、加えて、接着剤
の使用も廃止できるという効果がある。According to this embodiment, the nylon bobbin can be used even in a two-piece field core structure, and the use of adhesive can also be eliminated.
本発明によれば、低コストな鍛造鉄心と、樹脂製ボビン
との組み合わせが可能となり、経済性に優れた製品を供
給することができる効果がある。According to the present invention, it is possible to combine a low-cost forged iron core with a resin bobbin, and it is possible to supply a product with excellent economic efficiency.
また、界磁鉄心の組み立て時に、手間の掛る接着剤使用
の工程を省略できるので、生産効率の向上が図れるとい
う効果もある。Furthermore, since the time-consuming step of using adhesive can be omitted when assembling the field core, production efficiency can be improved.
