摘要： A hydrodynamic bearing design is disclosed incorporating a flexible membrane at one end of the fluid gap in the hydrodynamic bearing. If voids exist in the fluid, and if changes in the size of these voids or bubbles occur with changes in temperature or pressure in which the disc drive is being used, then the volume of the fluid will change, and increase relative to the change in size of the volume of the surrounding physical part. The flexible membrane will yield to the increased pressure of the increasing volume of the fluid. The membrane essentially acts as a spring whose spring force is overcome by the pressure created by or accompanying a increase in volume in which the lubricating fluid is contained, and preventing its escape or being forced out of the inner region of the bearing.

摘要： The present invention includes four sections or partitions: two thrust bearings which are formed by the sides of a grooved thrust plate and corresponding countersurfaces, the thrust bearings designed to cause fluid flow in a single direction up around the rotating thrust plate and upward along the surface of a rotating journal, and two journal bearings formed side-by-side on the journal formed between a rotating shaft and a bushing with multiple spiral-grooved sections being formed on the rotating shaft or in the stationary bushing. The two journal bearings are separated by a circumferential groove in the shaft which is connected by a radial bore to a hollow reservoir in the shaft for providing fluid to the journal bearing and the thrust bearing. By providing this bore and a second bore located near to the thrust bearing, the boundary conditions for the combined journal bearings and thrust bearings are fixed and a stable rotating shaft is achieved.
摘要翻译：本发明包括四个部分或隔板：两个推力轴承，由推力推力板的侧面和对应的对接面形成，推力轴承设计成使流体沿单一方向沿着旋转止推板向上流动并沿着表面向上一个旋转轴颈和两个在轴颈上并排形成的轴颈轴颈，形成在旋转轴和衬套之间，多个螺旋槽部分形成在旋转轴上或固定衬套中。两个轴颈轴承由轴中的圆周凹槽分隔开，该圆周槽通过径向孔连接到轴中的中空容器中，用于向轴颈轴承和止推轴承提供流体。通过提供该孔和位于推力轴承附近的第二孔，组合的轴颈轴承和推力轴承的边界条件是固定的，并且实现了稳定的旋转轴。

摘要： An apparatus for forming grooves in the surface of an article is disclosed. The apparatus includes a cage which has a circular cage wall with an annular pattern of holes in the wall. The apparatus also includes a plurality of spherical balls, each rotatably disposed in a respective hole of the cage wall and has a diameter greater than the wall thickness. The apparatus further includes a pin located within the cage, the pin has a circumferential groove in a plane coincident with the plurality of spherical balls and holes in the cage wall so that the pin holds the balls in the groove, the balls protruding through the cage wall and engaging the surface of a workpiece to be grooved so that the balls roll in the groove in the pin and, with movement of the workpiece and the apparatus, cause grooves to be formed in the interior surface of the workpiece. Lastly, the apparatus further includes an object at either end of the pin for holding the pin against translational movement relative to the cage with movement of the apparatus and the workpiece so that only a rotational movement is imparted to the pin by rotation of the workpiece.
摘要翻译：公开了一种用于在制品表面形成槽的装置。该装置包括一个具有圆形笼壁的保持架，该壁在壁中具有孔的环形图案。该装置还包括多个球形球，每个球可旋转地设置在保持架壁的相应孔中并且具有大于壁厚的直径。该装置还包括位于保持架内的销，销具有与保持架壁中的多个球形球和孔相重合的平面中的周向槽，使得销将球保持在槽中，球通过保持架突出并且与要沟槽的工件的表面接合，使得滚珠在销中的凹槽中滚动，并且随着工件和设备的移动，在工件的内表面中形成凹槽。最后，该装置还包括在销的任一端处的物体，用于通过设备和工件的移动来相对于保持架保持销的平移运动，使得仅通过工件的旋转赋予销的旋转运动。
