SOLUTION: A thrust board 10 which thrusts/supports a lower end face of a rotation shaft 7 is constituted at a base of a bearing housing 12a.

A suction magnet 9 sucking the rotation shaft 7 formed of a magnetic material by magnetic suction force is arranged at a lower part of the thrust board 10 as a magnetic suction means. A lower end and a radial outer periphery of the suction magnet 9 are surrounded by a bottomed cylindrical tip holder 11. The tip holder 11 is formed of a sintering metal member of a magnetic substance. The lower end of the tip holder 11 is integrally formed by insertion molding so that it is exposed from a lower end of a frame 12. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a flywheel power-storage device in which durability of bearing parts is improved by reducing axial loads in the flywheel bearing-parts, and energy efficiency is improved by reducing the core loss caused by rise in induced voltage caused by a permanent magnet. SOLUTION: The flywheel power storage device includes permanent magnets 2 each having recessed cross-sectional shape on the upper parts of the flywheel 3, and 2nd permanent magnets 4 each having the same shapes, cross-sections as the permanent magnets 2, and magnetic poles opposite to those of the permanent magnets 2. The permanent magnets 2, 4 are placed oppositely to each other, having a space between them in the housing 1. Thus, loads applied on the bearings 5, 6 in the flywheel 3 are reduced, and the magnetic flux is concentrated between the permanent magnet 2 and the 2nd permanent magnet 4. Consequently, the rise in induced voltage is restrained to reduce the core loss. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a roller bearing device capable of semipermanently keeping the force generated in accompany with the relative motion of a plurality of raceway members, such as rotating torque, at a low level.
SOLUTION: An outer ring 1 and an inner ring as the raceway members are magnetized in the direction orthogonal to a rolling raceway of rollers 3, and the rollers 3 mounted in the raceway are also magnetized in the direction of a central axis. The outer ring 1 and the inner ring 2 are concentrically mounted while aligning the direction of the magnetized magnetic field, and the rollers 3 are assembled in a state that the direction of the magnetic fields are aligned to the direction of the magnetic fields of the outer ring 1 and the inner ring 2. By applying this constitution, as the the same magnetic poles of the inner and outer rings (raceway member) and the rollers 3 are arranged in adjacent to each other, the repulsive force by magnetic force is generated among these components, and the torque of the bearing can be reduced. Further in this friction reducing method, the effect can be semipermanently kept without impairing of the performance caused by abrasion of the rollers 3 and flange parts 1a, 1b.

摘要翻译：要解决的问题：提供一种滚动轴承装置，其能够将伴随着诸如旋转扭矩的多个滚道构件的相对运动产生的力半永久地保持在低水平。解决方案：作为滚道构件的外圈1和内圈在与滚子3的滚动滚道正交的方向上被磁化，并且安装在滚道中的滚子3也沿着中心轴的方向被磁化。外圈1和内圈2在对准磁化磁场的方向的同时安装，并且辊3以使得磁场的方向与外部的磁场的方向对齐的状态组装通过应用这种构造，由于内圈和外圈（滚道构件）和滚子3的相同的磁极彼此相邻地布置，所以通过磁力产生的排斥力在这些部件和轴承的扭矩可以减小。此外，在该摩擦减小方法中，可以半功能地保持效果，而不会损害由辊3和凸缘部1a，1b的磨损引起的性能。版权所有（C）2005，JPO＆NCIPI

摘要： Thin-profile spindle motor. Single hydrodynamic-pressure thrust and radial bearings are established about a thrust plate on the end of the motor shaft, encompassed by a cylindrical casing. Hydrodynamic pressure-generating grooves scored on either of the thrust plate end faces, or either of the inner faces of the casing ends opposing the thrust plate end faces, are a component of the single thrust bearing. A micro-gap clearance for the thrust bearing, retaining lubricant continuously with the radial bearing, is established on whichever side of the thrust plate the thrust bearing is formed. Like grooves scored on either the thrust plate circumferential surface, or the casing inner cylindrical surface by which it is opposed at a micro-gap clearance, the clearance itself, and lubricant retained therein form the single radial bearing. Means for magnetically counterbalancing the thrust hydrodynamic-pressure are provided between rotor hub and the stator or casing.

摘要： A type of passive magnetic bearing that provides for both positive radial stiffness and significant levels of passive radial damping. Axial damping and axial forces can also be generated with minor modifications to the basic configuration. The bearing is comprised of a series of magnet, damping, and rigid non-magnetic elements essentially defining a laminated or composite structure. The damping material is directly mounted between the magnets and a rigid material, resulting in constrained layer damping. The range of motion of these floating, or soft mounted, magnets may also be restricted to generate higher stiffness in response to large vibrations.
