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： Oil which will serve as a lubricating fluid of a fluid dynamic pressure bearing is degassed in a first environment under a first pressure which is lower than atmospheric pressure. First and second members of the bearing are place in a second environment under a pressure lower than atmospheric pressure and higher than the pressure in the first environment. The degassed oil is supplied to the gap between bearing surfaces of the first and second members while the first and second members are in the second environment under pressure lower than atmospheric pressure and higher than the pressure in the first environment. Subsequently the pressure in the second environment is increased to force the oil into the gap between the bearing surfaces of the first and second members of the hydrodynamic fluid.

摘要： In a method for manufacturing a bearing member which is made of a porous material and has dynamic pressure grooves formed by electrochemical machining, the bearing member is impregnated with liquid such as hydrosoluble liquid or water prior to electrochemical machining. Since the hydrosoluble liquid or water is retained due to capillary force in the bearing member for which electrochemical machining is to be performed, the hydrosoluble liquid or water is not replaced with an electrolyte used in the electrochemical machining. Thus, the step of removing the electrolyte after electrochemical machining can be omitted, increasing production efficiency. Moreover, the bearing member is free from a trouble of rust as the electrolyte does not remain in the bearing member. Since the hydrosoluble liquid or water exhibits excellent affinity for the electrolyte, it does not harm processing accuracy in electrochemical machining and can be easily removed after electrochemical machining.
摘要翻译：在由多孔材料制成并具有通过电化学加工形成的动压槽的轴承构件的制造方法中，在电化学加工之前，轴承构件被浸渍有诸如水溶性液体或水的液体。由于在要进行电化学机械加工的轴承部件中由于毛细管力而保持水溶性液体或水，所以水溶性液体或水不会被用于电化学加工的电解质所取代。因此，可以省略电化学加工后除去电解液的步骤，提高生产效率。此外，由于电解质不残留在轴承部件中，所以轴承部件没有生锈的问题。由于水溶性液体或水对电解质具有优异的亲和性，因此不会影响电化学加工的加工精度，并且在电化学加工后可以容易地除去。

摘要： Fluid-dynamic-pressure bearing manufacturing method for more efficient and fail-safe degassing of bearing oil. Method makes it possible to prevent the generation of air bubbles in the course of an oil-charging operation that amounts to a step following degassing, and to single out the causative source of air bubbles when their generation has been detected. At the same time oil that is under a reduced-pressure environment within an oil-storing vacuum chamber is vacuum-degassed, immersed within the oil a stirrer for agitating and degassing the oil is rotated by indirect drive means, and the oil after having been degassed is supplied to a vacuum chamber where a fluid-dynamic-pressure bearing unit is retained—which has been pumped down to a pressure below the pressure within the oil-storing vacuum chamber—and is charged into the bearing clearances by raising the internal pressure of the bearing-retaining vacuum chamber.

摘要： A typical dynamic bearing design comprises a ring shaped or circular thrust plate mounted at or near the end of a shaft, the shaft defining together with a surrounding sleeve a journal bearing by providing grooves on only one of the two surfaces facing the gap between the shaft and sleeve. On the ring shaped thrust plate supported by the shaft, the traditional upward thrust bearing defined between the lower face of the thrust plate and the facing surface of the sleeve is maintained; but no grooves are on the surface of the thrust plate distant from the shaft and a facing counterplate surface. Further, the journal bearing is defined to have an asymmetry so that a bias force pressure along the surface of the shaft toward the thrust plate is established. The combination of the journal groove asymmetry pumping action toward the shoulder or thrust plate, together with the single grooved thrust bearing, is sufficient to establish a constant pressure between the distal surface of the thrust plate and the facing counterplate, as well as between the groove thrust plate and the facing shoulder surface.
