Title (EN) AXIAL FAN
(FR) VENTILATEUR AXIAL
(JA) 軸流ファン
Abstract:
(EN) An axial fan (10) comprises: a shaft (11), which is a rotating shaft; an air dynamic pressure bearing (34) that through air dynamic pressure minimizes radial shifting of the shaft (11); a metal frame (13) having a circular surface in the middle of which is provided a first hole through which the shaft (11) passes, and having a cylindrical shape closed at one end; and a resinous impeller (2) which covers the frame such that the frame (13) is accommodated in the interior, and which is centered between the shaft (11) and the inner side of a second hole provided to the center of the circular surface.
(FR) La présente invention concerne un ventilateur axial (10) qui comprend : un arbre (11), qui est un arbre rotatif ; un palier à pression dynamique d'air (34) qui, par pression dynamique d'air, réduit au minimum le décalage radial de l'arbre (11) ; un cadre métallique (13) ayant une surface circulaire au milieu de laquelle est ménagé un premier trou que traverse l'arbre (11) et ayant une forme cylindrique fermée à une extrémité ; et une roue en résine (2) qui recouvre le cadre de telle sorte que le cadre (13) soit logé à l'intérieur et qui est centré entre l'arbre (11) et le côté intérieur d'un second trou ménagé au centre de la surface circulaire.
(JA) 軸流ファン(10)は、回転軸であるシャフト(11)と、空気動圧によりシャフト(11)のラジアル方向の変動を抑制する空気動圧軸受(34)と、シャフト(11)が貫通する第1の穴が中央に設けられた円形状の面で円筒形状の一端が塞がれた形状の金属製のフレーム(13)と、フレーム(13)を内部に収納するようにフレーム(13)に被さり、円形状の面の中央に設けられた第2の穴の内側とシャフト(11)との間で芯出しされた樹脂製のインペラー(2)とを備える。
