Description
アル軸受セクションの全体または一部は、電気ステータとロータとの間の磁気ギャップに位置している。たとえば風損(ステータボア内のロータの相対移動および空気軸受内の軸受面および空気の相対移動によって引き起こされる)および電磁損からの熱をロータおよび軸受から逃がす必要があることが明らかになっている。
本発明の第1の局面に従って、電気機械は、電気ステータを支持するステータ本体を有するステータとロータとを備える。上記ロータは、ラジアル気体軸受を形成するラジアル軸受セクションとアキシャル気体軸受を形成するアキシャル軸受セクションとを備える軸受によって支持され、これらの軸受セクションのステータ側部分は、ステータ側ラジアル軸受部分およびステータ側アキシャル軸受部分であり、上記ステータ側ラジアル軸受部分および上記ステータ側アキシャル軸受部分は、互いに剛性的に接続され、ともにステータ軸受構造を形成する。上記ステータ側ラジアル軸受部分は、ブッシングであり、上記ブッシングは、冷却体によって径方向に取り囲まれ、上記ブッシングは、熱伝導性充填材を備える弾性支持体によって上記冷却体に接続される。
・固体、たとえばシリコーンもしくはシリコーン発泡体、または
・流体もしくは流動可能な材料、たとえばペーストもしくはゲル、特に
・液体、たとえば添加剤を有する油。
向長さの少なくとも20%または40%または60%または80%にわたって熱伝導性充填材を介して冷却体に熱結合される。
実施形態では、ステータ軸受構造は、第1の端部から第2の端部まで電気機械の軸方向に延在しており、ステータ軸受構造は、2つの端部のうちの一端の付近でステータの他の部分によって剛性的に支持されており、他端の付近で弾性的に支持されているかまたは全く支持されていない。
実施形態では、ステータ軸受構造は、ステータの他の部分に剛性的に取り付けられたステータ側アキシャル軸受部分、特にアキシャル軸受アセンブリによってこれらの他の部分に取り付けられる。
の軸に沿って装着可能な(装着状態または非装着状態において)概して円錐形のシェルである。
本発明の主題について、添付の図面に示されている例示的な実施形態を参照して以下の本文の中でより詳細に説明する。
得て、各ループは、少なくとも1つの弾性要素を備える。逆に、アキシャル軸受アセンブリ11およびブッシング18は、過剰に制約されたループまたは配置の一部ではない。
・冷却体71へのアキシャル軸受アセンブリ11の取り付け
・冷却体71へのブッシング18の取り付け。
