    • A method for manufacturing a hydro dynamic bearing device is provided. This method is capable of sufficiently increasing a circumferential speed at the time of grinding an axial member which is a structural component of the hydro dynamic bearing device, and also capable of preventing the generation of centrifugal whirling to improve the grinding efficiency and working efficiency while improving the quality of the product. The axial member as one of structural component of the hydro dynamic bearing device is supported at both ends thereof with a pair of plate members in a face-contact manner, while rotating the axial member around its axial center. The outer peripheral surface of the axial part of the axial member is ground on a grindstone while supporting the outer peripheral surface of the axial part with a supporting member. Also, the plate member contacting with the flange part of the axial member in a face-contact manner has at least a roll-off part formed in a predetermined area of the rotational center of the contact surface thereof. Furthermore, the contact part of the plate member to the flange part is elastically supported by a elastic member.
    • 提供一种制造水动力轴承装置的方法。 该方法能够充分提高在作为水动力轴承装置的结构部件的轴向部件的研磨时的圆周速度,并且还能够防止产生离心旋转以提高研磨效率和工作效率,同时改善 产品的质量。 作为水动力轴承装置的结构部件之一的轴向构件在其两端以面接触方式被支撑,同时使轴向构件围绕其轴向中心旋转。 轴承构件的轴向部分的外周面在磨石上研磨,同时用支撑构件支撑轴向部分的外周面。 此外,与轴向构件的凸缘部以面接触方式接触的板构件至少具有形成在其接触表面的旋转中心的预定区域中的滚降部分。 此外,板构件到凸缘部的接触部分由弹性构件弹性地支撑。

    • A method for manufacturing a hydro dynamic bearing device is provided for the finishing treatment of lubricating oil after lubricating the hydro dynamic bearing device, specifically for properly and effectively wiping off the lubricating oil adhering to the outside of the housing and adjusting the oil-level height of the lubricating oil filled in the housing. The method for manufacturing the hydro dynamic bearing constructed of an axial member housed in a housing, a radial bearing part for supporting the axial member in a non-contact manner in a radial direction by a hydro dynamic pressure action of the lubricating oil generated in a radial bearing clearance, and a sealing part arranged in an opening part of the housing, has the steps of: applying the lubricating oil to an unlubricated hydro dynamic bearing device; and blowing a gas on the outer peripheral surface of the housing, while sucking the lubricating oil from the sealing space of the sealing part or the vicinity thereof using a suction device that generates a negative-pressure suction force.
