【考案の詳細な説明】
この考案は水車またはポンプ水車（以下単に水車という
）の案内羽根に関する。[Detailed description of the invention] This invention relates to a guide vane for a water wheel or a pump water wheel (hereinafter simply referred to as a water wheel).
尚、ここで、案内羽根を以下羽根部と軸部を総称したも
のとする。Here, the guide vane will be collectively referred to as the vane portion and the shaft portion.
従来水車の案内羽根は、羽根部と軸部の案内羽根全体を
一体に鋳造するか、あるいは軸の材料に鍛鋼または鋳鋼
を用いた構造等が採用されていた。Conventionally, the guide vanes of water turbines have been constructed such that the entire guide vane of the vane and shaft are integrally cast, or the shaft is made of forged steel or cast steel.
しかしながら、これらはいずれも製作原価が高いという
欠点があった。However, all of these had the drawback of high manufacturing costs.
この考案の目的は、上記した従来構造の欠点をなくシ、
従来より製作原価の安い水車の案内羽根を提供するにあ
る。The purpose of this invention is to eliminate the drawbacks of the conventional structure mentioned above.
An object of the present invention is to provide a guide vane for a water wheel whose manufacturing cost is lower than conventional ones.
本考案の特徴とするところは、羽根部と軸部とよりなる
水車またはポンプ水車の案内羽根において、前記羽根郡
全体の厚さ方向の一部、及び前記軸部全体の厚さ方向の
一部を形成する一枚の鋼板と、この鋼板に重ね合せて溶
接し羽根部と軸部の残りの部分を形成する鋼板とよりな
る水車またはポンプ水車の案内羽根を提供するにある。A feature of the present invention is that, in a guide vane for a water turbine or a pump water turbine that includes a blade part and a shaft part, a part of the entire blade group in the thickness direction and a part of the entire shaft part in the thickness direction To provide a guide vane for a water turbine or a pump water turbine, which is made of a single steel plate forming the blade and a steel plate superimposed on this steel plate and welded to form the remaining parts of the blade part and the shaft part.
以下この考案を図に示した実施例により説明する。This invention will be explained below with reference to embodiments shown in the drawings.
所定の厚みの１枚の鋼板を、軸部全体１の厚さ方向ａの
一部２および羽根郡全体３の厚さ方向ａの一部４の形状
に平面方向全面すにわたって切断し、さらに別の鋼板に
よって軸部１から前記軸の一部２を差し引いた残りの部
分５及び羽根部３から前記羽根の一部４を差し引いた残
りの部分６を作製する。One steel plate of a predetermined thickness is cut across the entire plane in the shape of a part 2 in the thickness direction a of the entire shaft portion 1 and a part 4 in the thickness direction a of the entire blade group 3, and then cut into another shape. A remaining portion 5 obtained by subtracting the portion 2 of the shaft from the shaft portion 1 and a remaining portion 6 obtained by subtracting the portion 4 of the blade from the blade portion 3 are manufactured using steel plates of .
前記一部の軸２に対し、前記残りの軸部分５をのせ溶接
７によって、これらの接合せしめる。The remaining shaft portion 5 is placed on the partial shaft 2 and joined by welding 7.
また、前記一部の羽根４に対し、前記残りの羽根部分６
をのせ溶接８によってこれらを接合せしめる。Moreover, for the part of the blade 4, the remaining blade part 6
These are joined by welding 8.
溶接７及び８は例えば図面のＣ方向にエレクトロスラグ
溶接などにより行う。Welds 7 and 8 are performed, for example, by electroslag welding in the direction C in the drawing.
なお、軸２および５に対し面落し９を加工し、軸の仕上
り形状である円柱１０の切削加工に便ならしめる。Incidentally, the shafts 2 and 5 are machined with a recessed surface 9 to facilitate cutting of the cylinder 10 which is the finished shape of the shafts.
付上述べた通り、本発明によれば、大量生産される１枚
の鋼板を用いて案内羽根の羽根部と軸部の一部が得られ
、かつ軸の不足分に相当する部分のみを溶接すればよい
ので、特に、超大径を有する案内羽根においては、その
生産コストを従来にくらべて著しく低減せしめることが
できる。As mentioned above, according to the present invention, the blade part and part of the shaft part of the guide vane can be obtained using a single mass-produced steel plate, and only the part corresponding to the missing part of the shaft can be welded. Therefore, the production cost can be significantly reduced compared to the conventional method, especially for guide vanes having an extremely large diameter.
また、羽根部を軸部の軸方向で分割して溶接結合する従
来のものに比べて、くり返しの曲げモーメントによる疲
労破壊の危険性を極めて少なくすることができる。Furthermore, compared to the conventional structure in which the blade portion is divided in the axial direction of the shaft portion and welded together, the risk of fatigue failure due to repeated bending moments can be extremely reduced.
