Description
ここでは、プラネタリギアセットの比率はi0であり、
i0=−zr/zs ・・・(式2)
zr=リングギアの歯の本数であり、zs=太陽ギアの歯の本数である。
Tsωs + Tcωc + Trωr = 0 ・・・(式3)
次に図5を参照すると、HPスプール21とLPスプール29の間に配設した可変式磁気ギアボックス110を有するターボファンエンジン10が、概略的に示されている。磁気ギアボックス110の外側リング116はHPスプール21に結合し、内側リング112はLPスプール29に結合し、第3リング114はモータ/発電機(M/G)160に結合する。エンジン10は、HPスプール21に結合して、スタータ/発電機164,166を駆動する従来的なギアボックス162をも含み、航空機システムのための主要な電力供給源を提供する。本発明は、エンジンの高速および低速のスプールを接続する2つ以上のスプールを有するエンジンに対しても適用され得ると理解すべきである。中間リング114は、M/G160に結合する。中間リング114は、2つの効果的なリング114bおよび114cに分割されても良く、それらは、中間リング114が磁気ギアボックス110によってエンジンスプール21,29の間に準備される結合が何も存在しないフリーホイールであるべく許容されて相殺するように、或いは内側リング112と外側リング116の間における結合の度合いすなわちパーセンテージを調節するように、磁場のフェージングを前進させるかまたは遅延させるべく制御可能に調整されても良い。これは、一般的なキー付きシャフト上に2つの個別リング114b,114cを取付けて、それぞれの磁場の位相調整を提供する制御手段(図示せず)を提供することによって達成されても良い。1つの代替的な方法は、それぞれの磁場のための外部的な位相制御装置(図示せず)を備えたインターリーブ式磁極114b,114cを有する単一の統合的なリング114を提供することである。特には中間リング114が磁気ギアボックス110によってエンジンスプール21,29の間に準備される結合が何も存在しないフリーホイールであるように許容することによって、磁気ギアボックス110に接続するシャフトの間における磁気的な結合を制御する能力は、HPスプール21およびLPスプール29のような2本のシャフトを切離すことが必要であるとき、安全性機能を提供する。HPスプール21、LPスプール29およびM/Gの構成は、以下で更に詳細に議論されるように、選択的に修正されても良く、内側リング112、中間リング114および外側リング116が、HPスプール21、LPスプール29およびM/Gの何れかに結合して、代替的なトルク伝達特性を達成すると留意すべきである。
