| description | To provide a centrifugal impeller including a circular main plate having an insertion hole in the center, a hub cylindrically formed coaxially ranging to the insertion hole while having an approximately truncated cone shaped outer face, and protruded from the circular main plate, and a plurality of vane parts twisted up toward the hub side and protruded from the circular main plate and the hub at a position of avoiding the overlap with each other when viewed from the direction along the axis of the insertion hole, for enabling the efficient and inexpensive manufacture while having a highly efficient three-dimensional shape.SOLUTION: A circular main plate 39, a hub 40 and vane parts 41 are integrally provided on a resin impeller body 35A, the impeller body 35A is formed with cutout hole 42 having a shape including the projection of the vane parts 41 in the direction along the axis of an insertion hole 38, and a resin interpolation member 36A having an interpolation part 44 smoothly ranging to the surfaces of the circular main plate 39, the hub 40 and the vane parts 41 while filling in the cutout hole 42 is joined to the impeller body 35A.SELECTED DRAWING: Figure 3
【課題】挿通孔を中央部に有する円形主板と、略截頭円錐形状の外面を有しつつ挿通孔に同軸に連なる筒状に形成されて円形主板から突出するハブと、そのハブ側に向かって捩じり上げられるとともに挿通孔の軸線に沿う方向から見て相互に重なり合うのを避ける位置で円形主板およびハブから突出する複数の羽根部とを備える遠心羽根車において、高効率な三次元形状を有しつつ効率よく低コストで製造可能とする。【解決手段】円形主板３９、ハブ４０および羽根部４１が樹脂製の羽根車本体３５Ａに一体に設けられ、羽根車本体３５Ａに、挿通孔３８の軸線に沿う方向での羽根部４１の投影を含む形状の切り抜き孔４２が形成され、当該切り抜き孔４２を埋めて円形主板３９、ハブ４０および羽根部４１の表面に滑らかに連なる補間部４４を有する樹脂製の補間部材３６Ａが羽根車本体３５Ａに結合される。【選択図】 図３ |
