摘要： Hydrodynamic bearing having a shaft relatively rotatable with respect to a surrounding sleeve and having a thrust plate on one end thereof rotating in a recess of the sleeve. The shaft is preferably interrupted by a equi-pressure groove accessing a central reservoir in the shaft and having journal bearings defined by herringbone patterns above and below the groove to stabilize and provide stiffness to the cartridge. The stiffness of the cartridge is further enhanced by a thrust plate carried at one end of the shaft and rotating in a recess of the sleeve and being used to define thrust bearings on either surface thereof.

摘要： To simplify fabrication of an integral hub piece, the opening between the upper and lower female cones in this hub has sufficient width or radial dimension to allow access to both cones from one side of the hub with the cutting tool. A cutting tool is used which has a width smaller than the opening between the cones. Preferably, the tool has a width which is about equal to or smaller than an angular dimension through this opening which is defined by extending surfaces of the upper and lower female cones. If this limitation is satisfied, both cones can be created with a single machine set up operating from one side of the integrated hub. Preferably the tool should only move orthogonal or parallel to the cutting tools rotational center axis.

摘要： In one example, an FDB motor having a shield member is provided. In one example, the method includes disposing a first member and a second member for relative rotation about an axis of rotation. An annular shield member is attached to the first member, the shield member disposed adjacent a fluid reservoir for containing a bearing fluid. The reservoir is filled through an aperture (e.g., a fill hole) in the shield member. Thereafter, the aperture is at least partially sealed. The aperture may be hermetically sealed via one or more laser pulses. In other examples, a two piece shield is provided for shielding a reservoir without a fill hole.

摘要： A seal with a primary axis lying in the radial direction so that the fluid bearing is primarily extending in the axial direction between the rotating shaft and surrounding sleeve is disclosed. The capillary seal is positioned with an opening adjacent an end of the fluid bearing gap, and comprises two walls which diverge as they extend radially away from the fluid bearing so that the fluid held in the radial capillary seal is maintained adjacent an end of the gap, while the size of the reservoir defined by the diverging walls provides a large reservoir volume. The seal uses an additional capillary defined by a narrow annulus between the rotating shaft and a seal wall end. The narrow annulus establishes very high shock resistance preventing fluid loss past the outer axial wall of the radially capillary seal, and defines a small surface area from which evaporation can occur.
摘要翻译：公开了一种具有主轴线位于径向方向上的密封件，使得流体轴承主要在轴向方向上在旋转轴和周围套筒之间延伸。毛细管密封件定位成具有邻近流体轴承间隙的端部的开口，并且包括两个壁，当它们从流体轴承径向延伸时分开，使得保持在径向毛细管密封件中的流体保持在间隙的端部附近而由发散壁限定的储存器的尺寸提供了大的储存器容积。密封件使用由旋转轴和密封壁端之间的窄环形物限定的附加毛细管。狭窄的环形区域具有非常高的抗冲击性，可以防止流体通过径向毛细管密封件的外部轴向壁的流体损失，并且限定了可能发生蒸发的小的表面积。

摘要： In one aspect, a fluid dynamic bearing system is provided. The system may include a first member and a second member disposed for relative rotation about an axis of rotation and having opposing substantially planar surfaces defining an axial gap. A bearing region is disposed circumferentially around the axis of rotation and a relatively large gap region is disposed circumferentially around the bearing region, the large gap region having an average gap distance greater than the bearing region. The large gap region further includes at least one support pad forming a localized narrow gap distance in the axial gap to provide support between the opposed surfaces at a radial distance greater than the bearing region. For example, the support pad may support the surfaces against an externally applied force or moment that may tilt one member relative to the other.

摘要： In one example, a FDB motor having a top-cover attached, EM biased bearing system is provided. The motor includes a shaft and rotor disposed for relative rotation, and an axial limiter for restricting axial movement of the rotor with respect to the shaft, wherein the axial limiter is wet or lubricated during contact. The limiter is spatially fixed with respect to one of the shaft or the rotor and disposed with an axial end surface opposing a surface portion spatially fixed with respect to the other of the shaft or the rotor to form a gap therebetween. The gap may be filled with a fluid such as bearing lubricant, thereby providing a lubricated or wet contact surface to restrict axial movement of the shaft and rotor. Additionally, one or both surfaces may include a groove or slot to provide circulation of fluid through the gap.
摘要翻译：在一个示例中，提供具有顶盖附接的EM偏置轴承系统的FDB电动机。马达包括一个设置用于相对旋转的轴和转子，以及用于限制转子相对于轴的轴向运动的轴向限制器，其中轴向限制器在接触期间被湿润或润滑。限制器相对于轴或转子中的一个空间地固定，并且设置有与相对于轴或转子中的另一个空间固定的表面部分相对的轴向端表面，以在它们之间形成间隙。间隙可以填充有诸如轴承润滑剂的流体，从而提供润滑或湿的接触表面以限制轴和转子的轴向运动。另外，一个或两个表面可以包括槽或槽，以提供流体通过间隙的循环。
