Abstract
【解決手段】スクイズフィルムダンパベアリング装置は、回転軸15,41の外周に嵌合する第1ベアリング14と、ベアリング保持部材44および第1ベアリング14のアウターレース46間に一対のシールリング53R,53Tにより区画されてスクイズフィルムを構成する環状空間54とを備える。環状空間54は、アウターレース46の外周面に臨む第1空間55と、アウターレース46の軸方向端面に臨む第2空間56とからなるので、第1空間55のスクイズフィルムで回転軸15,41の径方向の振動を制振し、かつ第2空間56のスクイズフィルムで回転軸15,41の軸方向の振動を制振することができ、小型軽量な構造で回転軸15,41の径方向および軸方向の振動を共に制振することができる。
