摘要： A motor or bearing which incorporates the use of a capillary seal adjacent a bearing race between the shaft and surrounding hub or housing. The seal may take a plurality of forms, including a straight capillary seal; a seal formed between the housing and a seal ball having different radius of curvatures (preferably with the housing internal surface having a larger radius); or a centrifugal capillary seal comprising a male cone supported on a fixed or rotating shaft, and a female cone supported on a housing. The use of a capillary seal rather than ferrofluid seal should also provide a reduction in resistance across the seal gap compared to a ferrofluid seal.

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： A robust spindle motor is provided having improved shock resistance for fluid containment, as well as enhanced air purging characteristics. In an aspect, axial displacement of relatively rotating components is restricted by utilizing a limiter situated adjacent to a limiter bushing forming an axial limiter gap therebetween. A fluid channel, at least partially diverging, extends from a hydrodynamic bearing to the axial limiter gap, and continues to a region beyond the axial limiter gap. In an aspect, an axially diverging slot is situated adjacent to the axial limiter gap. Power is reduced by reducing viscous drag between relatively rotating components, hydrodynamic bearing length is increased, and higher stiffness of the hydrodynamic bearing is provided. Fluid volume may be increased, thereby offsetting fluid evaporation losses and allowing for the use of lower viscosity lubricants.
摘要翻译：提供了一种坚固的主轴电动机，其具有改进的防止流体容纳的抗冲击性，以及增强的空气净化特性。在一个方面，相对旋转部件的轴向位移通过利用与限制器衬套相邻的限制器来限制，该限制器在其间形成轴向限制器间隙。至少部分发散的流体通道从流体动力轴承延伸到轴向限制器间隙，并且继续到超出轴向限制器间隙的区域。在一个方面，轴向发散的狭槽位于轴向限制器间隙附近。通过减少相对旋转部件之间的粘滞阻力来降低动力，提高流体动力轴承长度，提供更高刚度的流体动力轴承。流体体积可能增加，从而抵消流体蒸发损失并允许使用较低粘度的润滑剂。

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.
