Abstract
Description
例えば、特許文献1には、アクチュエータ内部への水、粉塵等の侵入防止のためにシャフトとボスの隙間を塞ぐゴム製のブーツを、有底円筒状の遮熱用カバーで保護する技術が開示されている。このカバーがあることで、アクチュエータ内部への伝熱はある程度緩和される。
このように、従来は、シャフト支持部からの伝熱を抑えるための構成を、コンパクトに設けることは難しかった。また、そもそも上記のような従来の構成では、シャフト支持部からの伝熱を抑えることは難しかった。
実施の形態1.
図1は、この発明の実施の形態1に係るシャフト支持部の耐熱構造を備えたアクチュエータ1の断面図である。そして図2は、アクチュエータ1の分解斜視図である。以下では、電制式モータを用いたアクチュエータとして説明するが、圧力式等、他の駆動方式のものであってもよい。
アクチュエータ1は、外部入出力コネクタ2に設けられたターミナル3に電圧が印加されると、固定子4に巻回されたコイル5に電流が流れ、複数の極に分極された固定子4がNS磁化する。そして、NS着磁されたマグネット6を有し、上端をブッシュ7a、下端をベアリング7bで保持された略円筒状の回転子8は、固定子4のNS磁化を受けて回転する。
外部入出力コネクタ2、ターミナル3、固定子4、コイル5、マグネット6、ブッシュ7a、ベアリング7b、回転子8と、それらを納めたモータハウジング10等が、図2におけるモータ部100を構成する。
ブッシュ11は、円筒部11aとフランジ11bとから成り、フランジ11bは、円筒部11aのモータ部100側の端部から延設されている。ブッシュ11は、内周面に接触するシャフト9の削れを抑えるために、例えば樹脂で構成される。
ブッシュ11の円筒部11aの外径は、ボス12の円筒部12aの内径よりほとんどの部分で小さく、円筒部12aと円筒部11aとの間には、空気層13が形成されている。
シール部材14,15を取り付けたブッシュ11が内部に圧入されたボス12は、ねじ16を用いるなどしてモータハウジング10に取り付けられる。なお、シール部材14を省略して、ブッシュ11をモータハウジング10に超音波溶着してもよい。
ブッシュ11、ボス12、空気層13、シール部材15が、シャフト支持部を構成する。
また、従来のようにボス等のシャフト支持部を覆うカバーを設ける必要は無く、コンパクトに耐熱構造を構成できる。
また、ボス12は金属製、一例としてアルミ製としたが、マグネシウム、銅等で構成してもよく、要はブッシュ11よりも熱伝導率の高い材料で構成されていればよい。
