(JA) 多孔質動圧軸受、流体動圧軸受装置、及びモータ
Abstract:
(EN) The wear resistance of this porous dynamic pressure bearing can be increased, without using high-hardness powder, by increasing the true density ratio of the porous dynamic pressure bearing (bearing member 8) to 90-95%
(FR) Selon l'invention, la résistance à l'usure de ce palier à pression dynamique poreux peut être augmentée, sans utiliser de poudre à dureté élevée, par accroissement du rapport de densité réelle du palier à pression dynamique poreux (élément de palier 8) jusqu'à 90 à 95 %.
(JA) 多孔質動圧軸受(軸受部材8)の真密度比を90~95%まで高めることにより、高硬度の粉末によることなく、多孔質動圧軸受の耐摩耗性を高めることができる。
