Description
一つ目は、主板と複数の翼とが一体となったファン本体と、シュラウドとを熱可塑性樹脂にて別々に成形し、超音波溶着等で接合する方法である。
二つ目は、シュラウドの裏側に複数の翼が一体となったファン本体と、主板とを熱可塑性樹脂にて別々に成形し、超音波溶着等で接合する方法である。
三つ目は、主板、シュラウド及び複数の翼とを熱可塑性樹脂にて別々に成形し、超音波溶着等で接合する方法である。
複数の溶着嵌合部を備えた主板またはシュラウドと、前記複数の溶着嵌合部と同数の羽根部材を熱可塑性樹脂で別々に成形し、主板またはシュラウドと羽根部材を超音波溶着にて一体化したターボファンであって、
前記溶着嵌合部は、溶着嵌合部に嵌め込まれる羽根部材の周囲を囲むように立設した壁部を備え、さらに底部内側面には傾斜部を備え、
前記羽根部材は、前記溶着嵌合部に嵌め込み、前記傾斜部と接触した状態で主板またはシュラウドと超音波溶着し、
前記溶着嵌合部の底部には、前記羽根部材と接触する帯状の凸部を設けた。
羽根部材は、主板またはシュラウドの溶着嵌合部に嵌め込まれて超音波溶着により接合される。溶着嵌合部は、羽根部材の周囲を囲むように立設した壁部を有する構成であり、羽根部材は精度よく位置決めされる。また溶着嵌合部の底部の内側面には羽根部材の角部を周回するように傾斜部が設けられている。羽根部材の底面の角部は、全周に亘この溶着嵌合部内の傾斜部と接触している。羽根部材の角部は、鋭く尖った形状となっているので、羽根部材の角部に溶着エッジがその全周に亘り存在することになる。このため羽根部材は、溶着嵌合部の傾斜部と全周に亘り溶着されることになる。従って従来よりも溶着長は長くなり溶着強度は格段に向上する。
また、羽根部材が溶着嵌合部の傾斜部と溶着される際に溶着が進行すると羽根部材の底部が帯状の凸部と接触し、過度に溶着が進行することを防止するとともに、ターボファンの最終寸法を確保することができる。
前記溶着嵌合部の底部と溶着後の前記羽根部材との間には、空間を設けた。
溶着嵌合部の底部と溶着される羽根部材との間には空間が設けられている。この空間は、溶着時に過度に溶融した樹脂の逃げ場として機能する。溶着時に溶融しすぎた樹脂がその空間内に収容され、溶着部分の溶着を阻害することが無くなる。従って、ターボファンの最終寸法を確保することが容易になると共に本来の溶着強度を安定して確保することができる。
主板12は、図1から図4に示すように、その中央部にモータを覆うように形成された凸形状のハブ122と、ハブ122の中心部にモータのシャフトが高さ方向(図1と図2の上下方向)に挿入されて固定されるボス121とを有している。また主板12の周縁部には、図3及び図4に示すように、羽根付シュラウド13と組立接合する際に羽根部134を嵌め込む溶着嵌合部124が羽根付シュラウド13の羽根部134の個数分設けられている。
羽根付シュラウド13を図1により説明する。羽根付シュラウド13は、シュラウド131と羽根部134により構成されている。図1に示すように、中央部には大きな開口部132を有している。周辺部133は、外周方向に略傾斜面を呈している。また周辺部133には、羽根部134を主板12に嵌合させる溶着嵌合部124(図1参照)と同数備えている。
羽根付シュラウド13の各羽根部134の溶着嵌合部124と嵌り込む部分の底部134Bの周縁部は、図7に示すように尖ったエッジ状の角部になっている。この角部134Cが羽根付シュラウドと主板を溶着する場合の溶着エッジの機能を果たす。また羽根部134の形状は、図1に示すように、風を押し出す正圧面とその反対面がその頂部から底部に亘り同一形状(ストレート)である。羽根部134は、複数枚あるので、ターボファンを軽量化するために、ブロー成形等の方法により空洞化することもできる。
上記のように構成された、主板12、羽根付シュラウド13を図1に示すように、主板12の溶着嵌合部124に羽根付シュラウド13の羽根部134を嵌め込み仮組する。このように仮組されたものを、以下ワークと称する。この際、図7(a)に示すように、主板12の各溶着嵌合部124の傾斜面128に各羽根部134の角部134Cが全周接触した状態となる。図7(a)に示すように羽根付シュラウド13の羽根部134の底部134Bの角部134Cは、尖ったエッジ状となっている。この角部134Cが溶着嵌合部124の内側面の底部に周回するように設けられた傾斜面128と全周接触している。また羽根部134の側面134Sは溶着嵌合部の壁部125にガイドされて位置決めされているので超音波溶着する前のワークは安定的姿勢を確保することができる。
