Abstract
【解決手段】ロータ組立体2は、シャフト6、ベアリング組立体7、インペラ8、及びシュラウド9を備える。インペラ8及びベアリング組立体7はシャフト6に取り付けられ、シュラウド9はインペラ8を覆うようにベアリング組立体7に取り付けられる。シュラウド9をベアリング組立体7に取り付けると、インペラ8はシュラウド9に対して自由に回転し、インペラ8とシュラウド9との間の隙間は、ロータ組立体2の振動に関係なく維持される。その結果、作動時にロータ組立体2からあまり騒音が発生しない。
【選択図】図2
Description
ロータ組立体2は、シャフト6、ベアリング組立体7、インペラ8、及びシュラウド9を備える。ベアリング組立体7及びインペラ8はシャフト6に取り付けられ、シュラウド9はインペラ8を覆うようにベアリング組立体7に取り付けられる。
各々のベアリング10、11は、インナーレース、複数のボールを支持するケージ、及びアウターレースを備える。ベアリング10、11は、段付き部の反対側でシャフト6に取り付けられる。各ベアリング10、11のインナーレースは、2つのベアリング10、11を所定距離だけ離間するように機能する段付き部に当接する。
インペラ8は、ベース15及び複数のブレード16を備える半開放遠心インペラである。ベース15は、その周りでブレード16を支持する空気力学的上面及びシャフト6を収容する中心ボア17を有する。次に、シャフト6は、締まりばめ及び/又は接着結合によってインペラ8に固定される。
