Title (EN) ROTARY MACHINE
(FR) MACHINE ROTATIVE
(JA) 回転機械
Abstract:
(EN) Provided is a rotary machine which is provided with a rotating resin impeller, a rotary shaft penetrating the impeller, and a fastening part that is screwed to the rotary shaft, wherein: the rotary shaft is provided with a through-shaft part that faces an inner peripheral surface of the impeller, a leading-end shaft part that is screwed to the fastening part, and a fastening reception part that holds the impeller interposed between itself and the fastening part; the through-shaft part is provided with a non-circular part in which a cross-section orthogonal to the rotational axis has an outline that deviates from a perfect circle line drawn with the rotational axis as center; and the impeller is provided with a coupling part that engages with the non-circular part.
(FR) L'invention concerne une machine rotative, laquelle machine comporte une hélice en résine rotative, un arbre rotatif pénétrant dans l'hélice, et une partie de fixation qui est vissée sur l'arbre rotatif, et dans laquelle : l'arbre rotatif comporte une partie d'arbre traversant qui fait face à une surface périphérique interne de l'hélice, une partie d'arbre d'extrémité avant qui est vissée sur la partie de fixation, et une partie de réception de fixation qui maintient l'hélice interposée entre elle-même et la partie de fixation ; la partie d'arbre traversant comporte une partie non circulaire dans laquelle une section transversale orthogonale à l'axe de rotation a un contour qui s'écarte d'une ligne de cercle parfait tracée avec l'axe de rotation comme centre ; et l'hélice comporte une partie d'accouplage qui vient en prise avec la partie non circulaire
(JA) 回転する樹脂製のインペラと、インペラを貫通する回転軸と、回転軸に螺合する締結部と、を備え、回転軸は、インペラの内周面に対向する貫通軸部と、締結部に螺合される先端軸部と、締結部との間でインペラを挟持する締結受け部と、を備え、貫通軸部は、回転軸線に直交する断面の外形が、回転軸線を中心とした真円から外れた非円形部を備え、インペラは、非円形部に係合する連結部を備えている回転機械である。
