Definitions
- the present invention relates to a sheet metal turbine housing employed in an exhaust gas turbocharger driven by exhaust gas of an engine to generate a supercharging pressure, and in particular, a technique for preventing debris from being shattered (continence) during a burst of a turbine rotor. About.
- turbocharger turbine housing is conventionally mostly a cast product
- the design taking into consideration the flow of the molten metal increases the overall thickness of the housing and increases the heat capacity.

Abstract
Description
そのため、エンジン始動時において、タービンを流れるガスが持つ熱量がハウジングに吸収されることでガス温度が下がり、タービン下流の触媒の温度上昇に悪影響を与える。そのため、近年、タービンハウジングの熱容量を下げるために板材で製作した板金タービンハウジングの適用が進んでいる。
さらに、特許文献3においても、板金から製造されたスクロール形状を有するハウジングと、該ハウジングを、隙間を有して包囲する外部シェルとを備えた二重シェル形のタービンハウジングが示されている。
さらに、特許文献2、3では、シェル構造を二重化することでコンテインメント性を向上することが開示されているが、二重化や肉厚増大による重量の増大を招く問題がある。
すなわち、リブ構造が、内側スクロール部と外側スクロール部との向かい合う空間内に配置される構造であるので、この空間内でリブ部がつぶれて衝撃エネルギーを吸収することができ、さらに強度を向上してコンテインメント性を向上できる。
図1を参照して、本発明の第1実施形態に係る板金製のタービンハウジングについて説明する。
このタービンハウジング1は、エンジンに搭載される排気ターボ過給機に組み込まれるものであり、内部にタービンホイール3が収容される。タービンホイール3は、ハブ部5とハブ部5の外周面に稙設された複数のタービン翼7によって構成され、該ハブ部5にはタービンシャフト9が結合している。また、タービンシャフト9は図示しないコンプレッサホイールに連結している。また、タービンホイール3は回転中心軸線Lを中心回転するようになっている。
また、スクロール部11の一端側は、タービンシャフト9を回転軸支する軸受が収容される図示されていない軸受ハウジングと連結するタービンハウジング15のフランジ部17に溶接接合され、スクロール部11の他端側は、シュラウド部13まで一体に形成されている。または、シュラウド部13と突き合わせ、もしくは重ね合わされて溶接接合されてもよい。
なお、スクロールリブ部21は、図19(A)のように、スクロール部11の周方向に延在しているが、図19(B)のように、周方向に直角なタービン軸方向に延びる形状が付加されて格子状に形成されてもよい。
図2は、スクロール部11を形成する板金部材を、プレス加工によって折り曲げ部P1と、折り返し部P2との曲げ加工によって、凸状に突出したリブ部(スクロールリブ部、シュラウドリブ部)21、23を形成したものである。このように、U字状に板金部材が重ね合されてリブ部が形成される。
また、図4のリブ部29、31は、図3で形成したリブ部25、27を、さらに矢印b方向に折り曲げて外壁面に重ね合わせることで形状をしており、該壁面との重合わせ部分を溶接しても良い。
なお、図2よりも図3の構造、図3よりも図4の構造の方がリブ部の強度が向上し、補強作用が向上する。
このように、リブ部21等を構成する折り返し部P2の内側に補強部材の、例えばバンドやワイヤW等を内包するように巻き込むことで、リブ部の強度がさらに向上する。
次に、図6、7を参照して、第2実施形態を説明する。
第2実施形態は、第1実施形態におけるスクロールリブ部21をスクロール部11の外壁面に、またはシュラウドリブ部23をシュラウド部13の外壁面にタービンの軸方向に複数列設置して、該リブ部21、23を、補強部材を巻き付ける際の位置決め用のストッパとするものである。
なお、ワイヤWやバンドの巻き付けは、スクロール部11の外周側の壁面、または、シュラウド部13の外壁面の何れか、または両方において行ってもよい。
次に、図8~図18を参照して第3実施形態について説明する。
第3実施形態は、スクロール部が内側スクロール部11と外側スクロール部41とから構成されることを特徴とする。
第1実施形態で説明した1重のスクロール部を内側スクロール部11として、その外側に外側スクロール部41が形成された2重のスクロール部構造である。
外側スクロール部41は、内側スクロール部11の外側に空間室44を介して、内側スクロール部11の形状に沿って覆う形状に形成されている。
外側スクロール部41は、一端部がタービンハウジング15のフランジ部17に溶接され、他端部がシュラウド部13の外壁面上に溶接される。
図8(B)には、外側スクロール部41の板状部材の外面側と内面側の両方の面にそれぞれ、リブ部(外リブ部)45aと、リブ部(内リブ部)45bとがそれぞれ形成されている。
図8(H)のように、内側スクロール部11と外側スクロール部41の2重のスクロール構造の夫々のスクロール部の側壁部分の向かい合う空間室44内に、内側スクロール部11にリブ部51aが形成され、外側スクロール部41にリブ部51bが形成される構造である。
この空間室44内でリブ部51a、51bがつぶれて衝撃エネルギーを吸収することができため、板金ハウジング1の板厚を上げることなく強度を向上してコンテインメント性を向上できる。
図8(I)のように、シュラウド部13を内側シュラウド部とし、外側スクロール部41の端部領域に形成される部分を外側シュラウド部42として定義する。
外側シュラウド部42が内側シュラウド部13の上面に溶接される位置よりもタービンホイール3側に位置して複数の凸状のリブ部(シュラウドリブ部)23が形成されている。このシュラウドリブ部23は、第1実施形態と同様である。
また、図12のリブ部63も同様に、図10のリブ部45a、45bを、矢印d方向に折り曲げることで形成されるリブ部の形状である。
このように、リブ部を構成する折り曲げ部P1と折り返し部P2の内側に補強部材である、例えばバンドやワイヤW等を内包するように巻き込むことで、リブ部の強度がさらに向上する。
