従来例の構成とその問題点
従来、斜流ファンは第１図（イ）、（ロ）に示すごとく
円すい斜面ａと軸受ｂ’４有するハブＣに複数の翼ｄを
ネジ、またはリベッ）ｅにて締結固定あるいは溶接固定
して構成されていた。これは斜流ファンのハブＣの斜面
形状のためハブＣと翼ｄが一体成形できないためである
。Conventional structure and its problems Traditionally, a mixed flow fan has a plurality of blades d screwed or riveted onto a hub C having a conical slope a and a bearing b'4 as shown in Figs. 1(a) and 1(b). It was constructed by fastening or welding. This is because the hub C and the blades d cannot be integrally molded due to the sloped shape of the hub C of the mixed flow fan.
しかし上記のような構成では翼ｄをハブＣに固定する場
合、取付誤差が生じ、斜流ファンの回転アンバランスが
発生し、振動騒音の原因となる他、組立工数が多く高価
なものになるという問題点を有していた。However, in the above configuration, when the blade d is fixed to the hub C, an installation error occurs, causing an unbalanced rotation of the mixed flow fan, which causes vibration noise, and requires a large amount of assembly man-hours and is expensive. There was a problem.
発明の目的
本発明は上記従来の斜流ファンの問題点を解決するもの
で、斜流ファンの回転アンバランスより生じる振動騒音
を低減した精度の高い斜流ファンを安価に製造すること
を目的とするものである。Purpose of the Invention The present invention solves the above-mentioned problems of the conventional mixed flow fan, and its purpose is to inexpensively manufacture a highly accurate mixed flow fan that reduces vibration and noise caused by unbalanced rotation of the mixed flow fan. It is something to do.
発明の構成
この目的を達成するために、本発明は斜流ファンのハブ
の斜面部を分割し、空気流入側の斜面部を円筒形とし、
翼を一体成形し、これに空気流出側の斜面部を嵌合固定
した構成としたものである。Structure of the Invention In order to achieve this object, the present invention divides the sloped part of the hub of the mixed flow fan, and makes the sloped part on the air inflow side cylindrical.
The blade is integrally molded, and the air outlet side slope portion is fitted and fixed thereto.
この構成による斜流ファンは回転軸に対する翼の取付誤
差が小さく、回転アンバランスが少ないため、振動の少
ないなめらかな運転が実現し、しかも組立工数が少なく
安価に製造することができる。A mixed flow fan with this configuration has a small mounting error of the blades with respect to the rotating shaft, and has little rotational unbalance, so smooth operation with little vibration is achieved, and it can be manufactured at low cost with fewer assembly steps.

孔１１が成形されている。Further, a bottle 6 is integrally formed in the vicinity of the air outflow side end 52L of the blade 5 in the axial direction. Reference numeral 7 denotes a hub portion in which a conical slope portion 8, a cylindrical portion 9, and an annular flat plate portion 10 are integrally molded, and a plurality of holes 11 are formed in the vicinity of the air outflow side end 8a of the slope portion 8.
翼部分１とハブ部分７はそれぞれ、翼部分１の円筒部４

部分７の孔１１が嵌合して第３図のようにネジ１２等に
よって固定される。この状態においてハブ部分７の斜面
部８と翼５は接する。The wing section 1 and the hub section 7 each correspond to the cylindrical section 4 of the wing section 1.
The cylindrical portion 9 of the hub portion 7, the pin 6 of the wing portion 1, and the hole 11 of the hub portion 7 are fitted together and fixed by screws 12 or the like as shown in FIG. In this state, the slope portion 8 of the hub portion 7 and the blade 5 are in contact with each other.
また、翼部分１の円筒部４と翼５は空気流入側端部５ｂ
のみにて一体となっていて翼５の形状が軸方向に対して
傾斜していても成形することができるので翼６の形状を
斜流ファンとして最高の効率になるようむかえ角やキャ
ンバを設定することができる。また翼部分１にて軸受２
と翼６が一体成形されるので軸（図示せず）に対する翼
５の取付誤差は少なくなりバランスのよいファンとなる
。Further, the cylindrical portion 4 of the blade portion 1 and the blade 5 have an air inflow side end 5b.
Since the shape of the blade 5 can be formed even if it is tilted with respect to the axial direction since it is integrated with a chisel, the facing angle and camber can be set so that the shape of the blade 6 can be used as a mixed flow fan to achieve the highest efficiency. can do. Also, the bearing 2 in the wing part 1
Since the blades 6 and 6 are integrally molded, errors in attaching the blades 5 to the shaft (not shown) are reduced, resulting in a well-balanced fan.
さらに翼５の空気流出側端部５ａは組立後はビン６が孔
１１に嵌合固定されるので翼５の余計な強度を必要とせ
ず翼５の肉厚を薄くでき、斜流ファンの特性を向上する
ことができる。Furthermore, after assembly, the air outflow side end 5a of the blade 5 has the bin 6 fitted into the hole 11 and fixed, so the blade 5 does not need extra strength and the thickness of the blade 5 can be made thinner, which has the characteristics of a mixed flow fan. can be improved.

きる。Effects of the Invention As is clear from the above embodiments, the mixed flow fan of the present invention divides the sloped part of the hub, makes the sloped part on the air inflow side cylindrical, integrally molds the blades and the bearing, and injects the air into this. The needle surface on the outflow side is integrally molded, and by integrally molding the bearing and the blade, the installation error of the blade is reduced and the rotational balance is improved. Since the camber can be set and the wall thickness can be made thinner, a mixed flow fan with good air blowing performance and less vibration and noise can be realized.
