Title (EN) SHAFT MEMBER FOR FLUID BEARING DEVICE, MANUFACTURING METHOD THEREFOR, AND FLUID BEARING DEVICE
(FR) ÉLÉMENT D'ARBRE POUR DISPOSITIF PALIER FLUIDE, PROCÉDÉ DE FABRICATION DE CELUI-CI ET DISPOSITIF PALIER FLUIDE
(JA) 流体軸受装置用軸部材及びその製造方法、並びに流体軸受装置
Abstract:
(EN) A shaft member for a fluid bearing device, said shaft member having at the outer circumference two bearing surfaces 31 and 32 separated from each other in the axial direction, and a central recessed section 33 formed between the bearing surfaces 31 and 32 and having a smaller diameter than the bearing surfaces. The central recessed section 33 is provided with a cylindrical surface section 331 comprising a grinding surface, and step sections 332 arranged on both sides of the cylindrical surface section in the axial direction and having a different diameter than the cylindrical surface section.
(FR) L'invention concerne un élément d'arbre pour un dispositif palier fluide, ledit élément d'arbre comportant au niveau de la circonférence extérieure deux surfaces d'appui (31 et 32) séparées l'une de l'autre dans la direction axiale, et une section centrale en creux (33) formée entre les surfaces d'appui (31 et 32) et ayant un diamètre plus petit que les surfaces d'appui. La section centrale en creux (33) comprend une section de surface cylindrique (331) comprenant une surface de meulage, et des sections à échelon (332) agencées des deux côtés de la section de surface cylindrique dans la direction axiale et ayant un diamètre différent de celui de la section de surface cylindrique.
(JA) 流体軸受装置用軸部材は、外周面に、軸方向に離間した二つの軸受面31,32と、軸受面31,32の間に形成された、軸受面よりも小径の中逃げ部33とを有する。中逃げ部33に、研削面からなる円筒面部331と、円筒面部の軸方向両側に配置され、円筒面部に対して径差を有する段差部332とを設ける。
