摘要： An improved rotational motor, such as a spindle motor for a disc drive, is provided. The motor first comprises a hub having a shaft portion and a horizontal body portion. The motor also comprises a sleeve surrounding the shaft portion of the hub. A fine first vertical gap is retained between the shaft and the inner diameter of the surrounding sleeve. In addition, a fine horizontal gap is provided between the upper hub portion and the top of the sleeve. A third gap is preferably provided between the hub and an outer diameter of the sleeve. The first vertical gap is filled with a lubricating liquid, such as a clean oil. A capillary seal is provided in the third gap. In one embodiment, the lubricating liquid extends into the horizontal gap. Oil pumping grooves are machined along the horizontal fluid gap. When the hub is rotated, the oil pumping grooves impel oil towards the shaft. This prevents any portion of the first vertical gap from becoming un-lubricated during rotation of the shaft.
摘要翻译：提供了一种改进的旋转马达，例如用于盘驱动器的主轴马达。电动机首先包括具有轴部和水平主体部的轮毂。马达还包括围绕轮毂的轴部分的套筒。在轴和周围套筒的内径之间保持精细的第一垂直间隙。此外，在上部毂部和套筒的顶部之间设置有细小的水平间隙。优选地，在轮毂和套筒的外径之间设置第三间隙。第一垂直间隙填充有润滑液体，例如清洁油。毛细管密封件设置在第三间隙中。在一个实施例中，润滑液体延伸到水平间隙中。沿着水平流体间隙加工抽油槽。当轮毂旋转时，抽油槽将油推向轴。这防止了第一垂直间隙的任何部分在轴的旋转期间不被润滑。

摘要： According to various embodiments of the invention, a motor with a rotatable hub having fluid dynamic journal and thrust bearings can be assembled from four major components: a spindle, a hub, a thrust washer, and a base. The spindle can integrate journal bearing, axial limiter, and ring seal functions. The hub can integrate journal bearing, thrust bearing, ring seal, axial limiter, capillary seal, and bumper functions. The thrust washer can integrate thrust bearing and lubricant circulation functions. The base can integrate capillary seal and lubricant storage and circulation functions. Each function can be integrated as structural feature in its corresponding component. The spindle, hub, and thrust bearing can be preassembled. The base can be loaded with lubricant prior to assembly with the spindle/hub/thrust bearing combination.

摘要： A hub and shaft are provided which are mounted for relative rotation by providing two conical bearings spaced apart along the shaft, and a bearing seat facing each conical bearing. Fluid is maintained in the gap between each cone and the facing bearing seat, supporting the cone and seat for relative rotation. The outer surface of the bearing seat is insulated from the remainder of the motor by a thermal insulator which extends at least part way along the outer surface of the seats. This insulator is effective at keeping the bearings warm even in a relatively low temperature environment in which the motor may be used. The insulator may comprise a cylindrical ceramic or similar low thermal conductivity material extending at least part way along the axial distance outside of the bearing cones. Alternatively, an air space may be defined in the outer surface of the bearing seat, extending at least part way between the bearing cones.

摘要： A method of designing an improved bearing system is provided. In one embodiment, the method for designing a fluid dynamic bearing system includes determining a first stability ratio for a first journal bearing configuration. The method further includes determining a second stability ratio for a second journal bearing configuration. In one embodiment, the first configuration has two sub-journal bearings and the second configuration has three sub-journal bearings. The two stability ratios may then be compared to determine whether adding a sub-journal increases the stability ratio of the bearing system.
