Beschreibung
Zusammenfassung:	磁盘驱动器包括外壳、中心轴、关于外壳被固定并与所述中心轴共轴的静止部件，以及可绕所述中心轴关于所述静止部件转动的可转部件。定子关于外壳被固定。转子被所述可转部件支承并与定子磁性耦合。至少一个数据存储磁盘被装附于所述可转部件并与之共轴。氢化轴承与所述静止部件和可转部件互相联系，并包含粘滞系数至少为110的基本液体、抗氧化添加剂、抗腐蚀添加剂和耐磨添加剂，它们对阻止所述氢化轴承中催化作用下降是有效的。 A disc drive (10) includes a housing (12), a central axis (80), a stationary member (34) which is fixed with respect to the housing and coaxial with the central axis, and a rotatable member (36) rotatable about the central axis with respect to the stationary member. A stator (38) is fixed with respect to the housing. A rotor (70) is supported by the rotatable member and is magnetically coupled to the stator. At least one data storage disc (16) is attached to and is coaxial with the rotatable member. A hydro bearing (37) interconnects the stationary member and the rotatable member and includes a blend of a base fluid (84) having a viscosity index of at least (110), an anti-oxidant additive, an anti-corrosive additive and an anti-wear additive, which are effective for resisting catalytic degradation in the hydro bearing.
