发明名称 Disk drive fluid dynamic bearing spindle
摘要 Described herein is a disk drive with a fluid bearing having a sleeve defining a bore that extends through a portion of the sleeve along an axis defined by the bore. The sleeve can have a first contact surface that extends in a direction transverse to the axis. A spindle is rotationally received within the bore, and the spindle and the sleeve permit relative rotational movement when the spindle is positioned within the bore. The spindle has a stopper with a second contact surface that extends in a direction transverse to the axis when the spindle is positioned within the bore. A portion of at least one of the first and second contact surfaces includes a softer material than that of the spindle and the bearing sleeve, and the first and second contact surfaces are configured to engage each other upon relative axial movement between the spindle and the sleeve.
