摘要： Air which would otherwise be entrapped in an O-ring seal groove in a hydrodynamic bearing arrangement is removable from the seal groove by providing at least one passage between the seal groove and an adjacent thrust plate recess. The air is removed from the seal groove though the passages by drawing a vacuum at a lower end of the bearing arrangement. Preferably, the passages are formed, at least in part, by grooves defined in the upper surface of a land formed between the seal groove and the thrust plate recess.

摘要： An electrode containing a dielectric layer on a surface of the electrode and an active zone containing a metal embedded below the surface of the electrode, wherein the electrode is configured to form a groove pattern on a workpiece by an electrochemical machining process is disclosed. The electrode is capable of manufacturing a workpiece such as a counter plate, a sleeve journal or a conical bearing containing a groove pattern for fluid dynamics bearing, the groove pattern having a pitch of less than 80 microns. The electrode could be made by a method including depositing a dielectric layer on a surface of a metal, depositing a photoresist layer on the dielectric layer, printing a groove pattern on the photoresist layer, etching or physico-chemically removing portions of the dielectric photoresist layers to form grooves in the dielectric layer; removing the photoresist layer; and filling the grooves with a metal to produce the electrode.

摘要： A system and method are described for ballizing and measuring a workpiece bore hole. In one embodiment, a ballizing unit having a distal end removably coupled to a ballizing member moves the ballizing member from a first position within the bore hole to a second position. A metrology unit having a distal end removably coupled to the ballizing member moves the ballizing member from the second position back to the first position. A sensor detects a force exerted on the ballizing member by the workpiece at a third position, which is located between the first and second positions.

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.
摘要翻译：为了简化集成轮毂件的制造，该轮毂中的上和下母锥之间的开口具有足够的宽度或径向尺寸，以允许使用切削工具从毂的一侧接近两个锥体。使用具有小于锥体之间的开口的宽度的切削工具。优选地，该工具具有大约等于或小于通过该开口的角度尺寸的宽度，其由上和下雌性锥体的延伸表面限定。如果满足这个限制，则可以使用从集成集线器的一侧操作的单个机器来创建两个锥体。优选地，该工具应该仅与切割工具旋转中心轴线正交或平行移动。
