図2に示すように、環状組立体60は、複数の要素からなる環状部材である翼環61と、翼環61の内周側に周方向に取り付けられた複数の静翼63と、静翼63の内周側に設けられた内側シュラウド64と、内側シュラウド64のフランジに固定された保持環62と、保持環62により保持されたシールリング65と、を有している。
嵌合溝2は、機械加工によって形成された溝である。故に、基準面4は機械加工によって形成された加工面であり、精度が確保されて形成されている。
また、本実施形態の翼環61の外周側縁部61aには、突起物68が設けられている。即ち、本実施形態の翼環61の外周側縁部61aは平坦とはされていない。
図2、及び図3に示すように、測定装置1は、板形状のベース部6と、ベース部6に取り付けられた棒形状のシャフト部7と、シャフト部7の先端側(翼環61の径方向内側)に取り付けられたプローブ部8と、データ処理部(図示せず)と、を有している。シャフト部7は、プローブ部8とベース部6とを連結する連結部として機能する。
シャフト部7は、ベース部6上に固定されているガイド部22に支持されて配置されている。ガイド部22には、ボール軸受が接続されている。これにより、シャフト部7はガイド部22の長手方向に変位可能となっている。
ガイドローラ24は、シャフト部7の端部に形成された雌ネジ穴に固定軸33を螺合し、さらに、ナット34によって固定軸33を締結することによって固定されている。ガイドローラ24の径方向位置は、この固定機構により調整することができる。
ダイヤルゲージ28は、測定子29(第三当接部)が保持環62の内周面62a(被測定部)に当接するように固定されている。ダイヤルゲージ28の径方向及び鉛直方向の位置は、ジョイント26によって調整可能である。
ボールキャスター32の径方向及び鉛直方向の位置は、ジョイント26によって調整可能である。本実施形態の測定装置1においては、ボールキャスター32の径方向及び鉛直方向の位置は、ボールキャスター32が、保持環62の上面35に当接するように調節されている。
まず、翼環61に保持環62を周方向に複数並べるように組み立てる。具体的には、翼環61に遮熱環67を用いて静翼63を固定し、静翼63と一体にされた内側シュラウド64のフランジに保持環62を取り付ける。
次いで、測定装置1を翼環61に取り付ける。具体的には、図4に示すように、被嵌合部材13を嵌合溝2に周方向より挿入する。これにより、図3に示すように、測定装置1のベース部6が翼環61に仮固定される。取り付けの際は、翼環61は分割された状態にあるため、嵌合溝2の端部より被嵌合部材13を挿入することができる。
上記ベース部配置工程にてガイドローラ24を固定した後、仮固定されたプローブ部8の測定子29を保持環62の内周面62aに当接させる。そして、仮固定されていたシャフト支持部30とプローブ部8を固定する。
次いで、この基準となる位置における翼環61に対する保持環62の位置を計測する。具体的には、プローブ部8を構成するダイヤルゲージ28の数値が、データ処理部に転送されて記録される。
次いで、ベース部6を周方向にスライドさせ、基準となる位置以外の各点の計測値を取得する。この際、被嵌合部材13は嵌合溝2の内部で移動し、ガイドローラ24のボール25が対向面5を周方向に転動する。
一方、取得された計測値が所定の設定範囲内にない場合には、翼環61に対する保持環62の取付位置が微調整される。これにより、翼環61と保持環62とが適正に位置決めされる。なお、この位置決め作業は、タービン53の2段静翼~4段静翼の各翼環61について行われる。
最後に、環状組立体60がタービン53のタービンケーシング55(ケーシング)に組み立てられる。
また、嵌合溝2を介して測定装置1を固定することによって、翼環61の鉛直方向上方に突起物68がある場合においても、測定装置1を翼環61に固定することができる。
また、遮熱環67を固定するための嵌合溝2を測定装置1の固定に利用することによって、測定装置1のベース部6を固定するための溝を新たに加工することなく、測定装置1を翼環61に固定することができる。
また、被嵌合部材13を嵌合溝2に沿ってスライドさせることによって、容易にベース部6と翼環61とを固定することができる。
例えば、本実施形態では、タービン53の翼環61と保持環62とを有する環状組立体60を測定対象としたが、これに限ることはなく、環状部材に周方向に複数並ぶ被組立部材を組み立てたものを測定対象とすることができる。
また、ベース部6と翼環61とを接続する被嵌合部材13を2つ設ける構成を示したが、その数は問わない。
