Description
冒頭で述べた形態の転がり軸受は、例えば米国特許第7384199号明細書、米国特許第6443698号明細書及び米国特許第6413046号明細書において公知である。これらの公知の転がり軸受のいずれの場合においても、ころ軸受として形成されているラジアル転がり軸受の外レースは、軸方向でばね部分により延長されている。ばね部分は、ねじ締結によりハウジング部分に固定されている。
本発明の根底にある課題は、弾性懸架される外レースを備える転がり軸受を従来技術に対して特に所要組付けスペースの面でさらに発展させることである。
この課題は、本発明により、請求項1の特徴を有する転がり軸受により解決される。この、特にガスタービンに好適な転がり軸受は、
−内レースと外レースとの間に配置される複数の転動体と、
−ハウジング構造と、
を備え、ハウジング構造に外レースがばね弾性的に取り付けられており、外レースは、一体的に形成されて、転動体のための転動軌道を形成する転動軌道部分と、ばね部分と、ハウジング構造に螺止されるフランジとを有しており、
ばね部分は、複数のばねバーから形成されており、ばねバーは、一方では、端面側で転動軌道部分に接続する変向部分に、他方ではフランジに接続しており、半径方向で転動軌道部分の外側に配置されていて、軸方向では、一方では変向部分から張り出さず、他方では転動軌道部分から張り出さないようになっている。

前記ばね部分(21)は、複数のばねバー(12)から形成されており、該ばねバー(12)は、一方では、端面側で前記転動軌道部分(7)に接続する変向部分(9)に、他方では前記フランジ(10)に接続しており、半径方向で前記転動軌道部分(7)の外側に配置されていて、軸方向では、一方では前記変向部分(9)から張り出さず、他方では前記転動軌道部分(7)から張り出さないようになっていることを特徴とする、転がり軸受。 - 前記ハウジング構造(8)は、少なくとも1つのハウジングディスク(15,16)を有する、請求項1記載の転がり軸受。
- 前記ハウジング構造(8)は、前記外レース(3)の前記転動軌道部分(7)に対する半径方向のストッパ及び軸方向のストッパを形成する、請求項2記載の転がり軸受。
- 前記ハウジング構造(8)は、前記外レース(3)の前記転動軌道部分(7)に対する軸方向両側のストッパを形成する、請求項3記載の転がり軸受。
- 前記ハウジング構造(8)は、付加的に前記外レース(3)の前記転動軌道部分(7)に対する周方向のストッパを形成する、請求項3又は4記載の転がり軸受。
- 前記ハウジング構造(8)は、複数の部分から形成されている、請求項5記載の転がり軸受。
- 前記ハウジング構造(8)は、バヨネット継手の形態で前記外レース(3)の前記転動軌道部分(7)に設けられた切欠きに係合する、請求項5記載の転がり軸受。
- 前記転動体(4)は、玉として形成されている、請求項1から7までのいずれか1項記載の転がり軸受。
