要約
(EN)
In order to manifest high centering effects from a low rotation range to a high rotation range and prevent noise generation in a floating metal bearing by the vibration-limiting effects resulting therefrom, the inner surface of a floating metal bearing is machined, the machining continuously providing multiple regions of differing fluid lubrication conditions (each region smoothly connecting a narrow flow path to a wide flow path by varying the clearance between the shaft surface and the inner surface of the bearing bore) on the bearing bore surface isotropically at equal angles from the shaft center.
(FR)
La présente invention concerne une surface interne d'un palier métallique flottant qui est usinée, dans le but de montrer d'importants effets de centrage depuis une plage de rotation faible vers une plage de rotation élevée et d'éviter la production de bruit dans un palier métallique flottant par les effets de limitation de vibration obtenus de celui-ci, l'usinage offrant continuellement plusieurs régions de différentes conditions de lubrification fluidique (chaque région raccordant de façon uniforme un trajet d'écoulement étroit à un trajet d'écoulement large en faisant varier le dégagement entre la surface d'arbre et la surface interne de l'alésage de palier) sur la surface d'alésage de palier de façon isotropique à des angles égaux par rapport au centre de l'arbre.
(JA)
 フローティングメタルベアリングにおいて、低回転領域から高回転領域まで高いセンタリング効果を発揮し、これによる振動抑制効果からノイズの発生を防止すべく、軸受穴の表面に流体潤滑条件の異なる領域(軸の表面と軸受穴の内面とのクリアランス量を変化させることにより、狭い流路と広い流路を穏やかに結ぶ一つの領域)を軸心から等角等方的に複数連続して備える内面加工を施した。
