Description
【発明の詳細な説明】 [産業上の利用分野コ 本発明はロータ体の製造方法に関する。[Detailed description of the invention] [Industrial application fields] The present invention relates to a method for manufacturing a rotor body.
[従来の技術]
磁石とシャフトからなるロータ体では磁石とシャフトを
接合する必要があるが従来は接着、かし[発明が解決し

しかし、この作業は接着剤を付ける際に、接着剤の貴、

点がある。[Prior art] In a rotor body made up of magnets and a shaft, it is necessary to join the magnets and the shaft, but conventionally the magnets and the shaft have to be joined by adhesive or crimping.[Problem to be solved by the invention] However, when applying adhesive, this work Adhesive noble,
There are many control items such as viscosity, position, shaft insertion speed, etc., and although it seems to be a simple operation, it has the disadvantage of being expensive.
[課題を解決するための手段]

ことを特徴とする。[Means for Solving the Problems] The present invention, when adhering a shaft to a magnet, immerses the magnet in epoxy resin, dries it at room temperature or with hot air, and then inserts the shaft into the magnet and heats it to harden the epoxy resin and bond it. It is characterized by doing.
エポキシ樹脂の中には2段階の硬化過程を経るもの、が

初の硬化状態をBステージと言う。Some epoxy resins undergo a two-step curing process. Generally, it hardens once in the range from room temperature to about 80 degrees Celsius, then softens as the temperature rises, and then rises further to 1.
The initial curing state in which the final curing reaction occurs at 20-150°C is usually referred to as the B stage.

が行われる。After a magnet is immersed in epoxy resin, if it is brought to a B-stage hardening state by drying at room temperature or with warm air, the magnet will be in the same state as before immersion in terms of handling. When a shaft is inserted into this magnet and treated at 120-150℃ for 1-4 hours, the resin that was in the B stage softens and enters the gap between the inner diameter of the magnet and the shaft, further increasing the temperature. As a result, the next step is to harden the magnet and the shaft.
[実施例コ 以下に本発明について実施例をもとに詳細に説明する。[Example code] The present invention will be described in detail below based on examples.

25μm, maximum diameter = 177μrIL), outer diameter 6
A ring magnet with an inner diameter of 2 mm and a thickness of 2.5 m was created.

じエポキシ樹脂をシャフトに直接付け、磁石に挿入して
接着したものも作成した。Each magnet was immersed in a solution of triethane containing 30% epoxy wood, dried at room temperature for 1 hour, and then the shaft (outer diameter 1.98 rran: the clearance between the inner diameter of the magnet and the shaft after immersion was α005 group). After inserting the shaft into which the epoxy resin was inserted, the shaft was cured at 150° C. for 1 hour to harden the epoxy resin, and the shaft was bonded. In addition to measuring the time required for bonding each piece, the adhesive strength (pulling force) of each bonded item was examined. For comparison, we also created a model in which the same epoxy resin was applied directly to the shaft, inserted into a magnet, and then glued.
接着に用した時間及び接着強度4を結果を第1表に示す
。Table 1 shows the results of the adhesion time and adhesion strength 4.
第1表より従来法に較べ約1/2の時間で接着ができし
かも強度的には殆んど同等の物が得られることがわかる
。From Table 1, it can be seen that adhesion can be achieved in about 1/2 the time compared to the conventional method, and a product with almost the same strength can be obtained.
第 1
表
また、シャフトを挿入して加熱するだけなので工程の機
械化も従来法にくらべ容易に行える。Table 1 In addition, since the shaft is simply inserted and heated, the process can be mechanized more easily than conventional methods.
以上that's all
