摘要： Part gap spacers that are disposed between parts in a fluid dynamic bearing motor or hard disk assembly are provided herein. Part gap spacers are designed to off-set adjacent parts such that part-to-part spacing has less variation in tolerance accumulation. Part gap spacers also allow for greater control of bond line thickness of adhesives, and control of gap distances for bearing fluids, and allows for electrical conductivity across bonded parts.

摘要： Methods for adhering parts together using part gap spacers are provided herein. Part gap spacers are formed in a selected pattern and a selected height on a surface of at least one surface of two parts to be oppositely disposed. When disposed opposite each other, at least some of the part gap spacers contact the opposite surface, and establish a standoff distance that is generally uniform, and thereby creating voids. Adhesive is disposed in at least some of the voids to adhere the part surfaces to each other. Further methods comprise forming part gap spacers on multiple sides of a third part to be disposed intermediate two surfaces. The part gap spacers can be formed in a variety of shapes, including bumps, tapers, ribs, and flange edges.

摘要： For a motor having fluid dynamic bearing(s) defined by surfaces of relatively rotatable motor members, aspects include providing a capillary reservoir between relatively irrotatable surfaces. The capillary reservoir may comprise a tapering gap that is vented to a gaseous environment through one end of the gap and is in fluidic communication with the fluid dynamic bearing(s) through another end of the gap. The gap may be axial, and the capillary reservoir may be disposed coaxially with one or more of the fluid dynamic bearing(s) about an axis of rotation. The capillary reservoir may extend from proximate a top portion of the motor to proximate a bottom portion of the motor.

摘要： An active fluid bearing system is provided. In one example, the active fluid bearing system includes an interface region formed between an outer surface of an inner member and an opposing inner surface of an outer member. The inner and outer members are disposed for relative rotation of the inner and outer members, and thereby form an interface region having a hydrodynamic bearing region and an active bearing region. A liquid is disposed in the interface region at the hydrodynamic bearing region, and is further disposed in the active bearing region if the inner and outer members are not relatively rotating. The bearing system is operable for evacuating at least a portion of the liquid from the active bearing region during relative rotation of the inner and outer members. The active bearing region may be a journal bearing or a thrust bearing.

摘要： For a motor having liquid lubricated bearing surface(s), aspects include providing a column shaped Capillary Seal (CS) for storing and supply lubricating liquid to the bearing surface(s). The column shaped CS may have a cross-section substantially topologically equivalent to a circle. Aspects include disposing the column shaped CS between relatively rotational motor members or between relatively irrotational motor members. Other aspects include disposition of the column shaped CS in a spiral shape where one opening of the CS fluidicly communicates with the bearing surface and another opening vents to a gas environment. Still other aspects include disposing the column shaped CS circumferentially on surfaces of generally cylindrical shaped motor members. Such surfaces may oppose a second surface that is one of relatively rotational and relatively irrotational vis the surface. The column shaped CS may circumscribe an axis of a rotating member or may be disposed parallel to the axis of the rotating member.
