本発明に係るターニング装置の態様は、ケーシングと、前記ケーシングよりも上方に取付けられた駆動モータと、前記ケーシングよりも上方であって、前記駆動モータの駆動軸上であって鉛直方向に平行な基準面に対する一方側に、前記基準面に交差する基準線周りに回転可能に支持され、前記駆動モータにより回転する駆動輪と、前記ケーシング内に配置されるとともに前記基準線に平行な軸線周りに回転可能に支持され、前記駆動輪と環状部材を介して接続された従動輪と、前記従動輪と同軸に接続され第一の平歯を有する第一の歯輪と、前記基準線に平行に延びる回転軸と同軸に設けられたホイールギヤ、及び前記第一の歯輪の前記第一の平歯にそれぞれ噛合う第二の平歯を有する第二の歯輪と、前記第二の歯輪を回転可能に支持するアーム部材と、前記アーム部材を移動させることで、前記第二の歯輪を、前記ホイールギヤに噛合う噛合い位置と、前記ホイールギヤに噛合わない退避位置との間で移動させる移動機構と、前記ケーシングに着脱可能とされ、前記駆動輪を覆うカバーと、を備え、前記回転軸の前記基準面に対する他方側に圧縮機が接続されることを特徴としている。
また、本発明に係る回転機械の態様は、上記のいずれかに記載のターニング装置を備えることを特徴としている。
以下、本発明に係る回転機械の第1実施形態を、回転機械が蒸気タービンである場合を例にとって図1から図4を参照しながら説明する。
図1に示すように、本実施形態の蒸気タービン1は、蒸気タービン1に流入する蒸気(作動流体)の量と圧力を調整する調整弁11と、圧力を保持する本体側ケーシング12と、動力を発生する動力発生部13と、発生した動力をコンプレッサ(圧縮機)69等の機械に伝達するロータ(回転軸)14と、ロータ14を軸線回りに回転可能に支持する不図示の軸受装置と、ロータ14を回転させるための本発明のターニング装置15とを備えている。
弁座20は、略円筒形状をし、その軸線はロータ14の軸線と直交している。弁座20の内径は、ロータ14に向かう方向に徐々に拡大し、先端部は蒸気室21に連通している。弁座20の蒸気室21とは反対側の端部の内面20aは、内側に向かって凸となる曲面状に形成されている。弁体19の下部の形状は、球体の一部分を形成しており、弁座20の内面20aに接離可能に設けられている。弁体19が、弁座20から離れると蒸気流路が開き、弁座20に接触すると蒸気流路が閉じられることになる。
蒸気室21は、調整弁11から流入する蒸気を動力発生部13に案内するものであり、略ドーナツ型形状をしている。蒸気室21の蒸気流路は内側に向かって行くに従って、狭くなるとともにロータ14の軸線と平行する向きに偏向している。
動翼24は、ノズル23で速度エネルギーに変換された蒸気のエネルギーをロータ14の回転エネルギーに変換する作用をする。
ロータ14は、動力発生部13で発生した動力をコンプレッサ69等の機械に伝達する作用をする。ロータ14と本体側ケーシング12との間には、蒸気等の漏れを防止する図示しないシール構造が設けられている。蒸気タービン1を作動させて仕事を終えた排気蒸気は、排気室31を通って図示しない復水器に送られる。
ターニング装置15は、図1から図3に示すように、ケーシング41と、ケーシング41に取付けられた駆動モータ42と、駆動モータ42の駆動軸42a上に規定されるとともに鉛直方向Zに平行な基準面Sに対する一方側D1に回転可能に支持された駆動側スプロケット(駆動輪)43と、ケーシング41内に回転可能に支持された従動側スプロケット(従動輪)44と、従動側スプロケット44と同軸に接続された平歯輪(第一の歯輪)45と、ロータ14に設けられたホイールギヤ30及び平歯輪45にそれぞれ噛合うピニオンギヤ(第二の歯輪)46と、ピニオンギヤ46を回転可能に支持するアーム部材47と、アーム部材47を移動させるための移動機構48と、ケーシング41に着脱可能とされたチェーンカバー(カバー)49とを備えている。
なお、図2の断面上に駆動モータ42は現れないが、説明の便宜上駆動モータ42を二点鎖線で示している。
基準面Sは、駆動モータ42の駆動軸42aを含み、鉛直方向Zに平行な平面である。
駆動モータ42は、ケーシング41よりも上方となる位置に、駆動軸42aが水平面に平行となるように取付けられている。ケーシング41に駆動モータ42は、図示しないボルト及びナットやビス等の公知の締結手段により取付けることができる。
駆動モータ42と駆動側スプロケット43との間には、減速機構58が設けられている。駆動モータ42を駆動することで駆動軸42a周りに回転する図示しないロータ軸は、その回転速度が減速機構58により減速されて、連結シャフト58aを介して駆動側スプロケット43に駆動力が伝達される。すなわち、駆動側スプロケット43は、減速機構58を介して駆動モータ42により回転する。
ピニオンギヤ46は、平歯輪45の第一の平歯45a、及びホイールギヤ30の平歯30aにそれぞれ噛合う第二の平歯46aを有している。
アーム部材47は、自身の長手方向の中間部において連結軸60周りに回転可能に支持されている。アーム部材47の一端部47aはアーム部材47の中間部から下方に延び、アーム部材47の他端部47bはアーム部材47の中間部から水平面にほぼ平行に延びている。
ピニオンギヤ46は、アーム部材47の一端部47aに、ピニオンギヤ46の軸線が基準線Cに平行となるように回転可能に支持されている。
ピニオンギヤ46の第二の平歯46aは、平歯輪45の第一の平歯45aに常時噛合している。
このように、本実施形態のターニング装置15は、従動側スプロケット44よりも下流側でホイールギヤ30に駆動力を伝達する歯車が、平歯輪45及びピニオンギヤ46の2段構成となっている。
エアシリンダ63のインナーロッド63aは、アウターケース63bに対して鉛直方向Zにスライド可能に延在されている。アウターケース63b内には、インナーロッド63aの下方側の部分が収容されている。エアシリンダ63のアウターケース63bは、スプリングブッシュ66を介してケーシング41に支持されている。
インナーロッド63aの上方側の部分は、嵌脱レバー64における連結部材65の他端部が連結された部分よりも他端部64b側に回転可能に連結されている。
この例では、嵌脱レバー64は棒状に形成され、基準面Sに平行な面上を回転する。
一方で、ピニオンギヤ46が噛合い位置P1に配置された状態からインナーロッド63aが下方にスライドした(没入した)場合には、インナーロッド63aが嵌脱レバー64の他端部64b側を引き下げ、嵌脱レバー64が一端部64a周りに回転して、ピニオンギヤ46がホイールギヤ30に噛合わない退避位置P2に配置される。
このように、移動機構48は、シリンダ制御部54の制御指令によりピニオンギヤ46を噛合い位置P1と退避位置P2との間で移動させることができる。
図1に示すように、ロータ14の基準面Sに対する他方側D2には、前述のコンプレッサ69が接続されている。ロータ14とコンプレッサ69との接続部分を覆うように、筒状のカップリングガード70が着脱可能に取付けられている。
まず、ターニング装置15の制御部52は、蒸気タービン1の運転時、エアシリンダ63のインナーロッド63aをアウターケース63bに没入された位置で保持させる。この際、駆動モータ42は停止状態となっており、ピニオンギヤ46は退避位置P2に配置されている。
また、制御部52が動作していないとき等には、嵌脱レバー64の他端部64b側を操作者が上下させることで、手動によりピニオンギヤ46の配置を噛合い位置P1と退避位置P2との間で調節することができる。
駆動モータ42の駆動力を伝達する歯車が、平歯輪45及びピニオンギヤ46の2段構成であることで、従来の歯車が3段構成である場合に比べて、部品点数を低減させるとともに剛性を高め、ターニング装置15の鉛直方向Zの長さを抑えて小型化することができる。駆動モータ42の駆動力の伝達効率を向上させることができる。
次に、本発明の第2実施形態について図5及び図6を参照しながら説明するが、前記実施形態と同一の部位には同一の符号を付してその説明は省略し、異なる点についてのみ説明する。
図5及び図6に示すように、本実施形態のターニング装置80は、第1実施形態のターニング装置15の各構成に加えて、一端部82aがラチェット機構81を介して駆動側スプロケット43と同軸に連結された回転レバー82を備えている。
なお、図5の断面上にラチェット機構81及び回転レバー82は現れないが、説明の便宜上ラチェット機構81及び回転レバー82を二点鎖線で示している。
ラチェット機構81は、駆動側スプロケット43の軸線である基準線C、すなわちスペーサ84に対して、回転レバー82の一端部82aが基準線C周りの一方側に回転するのを規制するとともに、基準線C周りの他方側に回転するのを許容する。つまり、回転レバー82の他端部82bを基準線C周りの一方側、他方側、一方側、と何度も往復するように回転させることで、駆動側スプロケット43を基準線C周りの一方側のみに回転させることができる。これにより、駆動側スプロケット43の回転が伝達されてロータ14が回転し、ロータ14の位相を合わせることができる。
回転レバー82、及び前述の嵌脱レバー64は、基準線Cに沿う方向において、チェーンカバー49に対する同じ側で回転する。
回転レバー82及び嵌脱レバー64が基準線Cに沿う方向においてチェーンカバー49に対する同じ側で回転するため、チェーンカバー49が障害となることなく、一人の操作者Qがターニング装置80の片側から両レバー64、82を容易に操作することができる。
例えば、前記第1実施形態および第2実施形態では、駆動輪が駆動側スプロケット43、従動輪が従動側スプロケット44、そして環状部材がチェーン59であるとした。しかし、駆動輪が駆動プーリ、従動輪が従動プーリ、そして環状部材が両プーリに掛け渡されたVベルトであるように構成してもよい。
回転機械が蒸気タービンであるとして説明したが、回転機械はこれに限られず、ガスタービン等でもよい。
