摘要： A superconductive bearing device includes a ring-like permanent magnet portion (2) disposed concentrically on a vertical axial rotor (1), and a superconductor (8) disposed below the permanent magnet portion (2) in such a manner as to face the lower surface of the former (2) with a vertical gap between them. The permanent magnet portion (2) comprises a disc (4) fixedly disposed on the rotor (1) and a plurality of ring-like permanent magnets (6a, 6b) so disposed on the disc (4) as to be spaced apart from one another in the radial direction of the rotor (1). The upper and lower end portions of each permanent magnet (6a, 6b) have mutually opposite magnetic polarities, and the corresponding end portions, in the vertical direction, of adjacent permanent magnets (6a, 6b) have opposite magnetic polarities. The gap of the permanent magnets (6a, 6b) in the radial direction is optimized on the basis of the dimension (width) of the magnets (6a, 6b) in the radial direction. Therefore, a load capacity and rigidity can be improved, shaft vibration of the rotor can be prevented and the rotor (1) can be supported stably in the non-contact state.

摘要： A superconductive bearing device for supporting rotatably a shaft (rotor) (2) rotating at a high speed, under a non-contact state. A superconductive bearing (4) for supporting the shaft (2) under a non-contact state to a housing (1) includes a permanent magnet (14) fitted to the shaft (2) and a second kind of superconductor (17) so fitted to the housing (1) as to be spaced apart from, and to oppose in a vertical direction, the permanent magnet (14). A touchdown bearing (21) consisting of a thrust ball bearing is disposed at the opposed portion between the housing (1) and the shaft (2). There is disposed an initial positioning mechanism which sets relative positions of the housing (1) and the shaft (2) by moving up and down a race (23) of the touchdown bearing (21) on the housing (1) side. This initial positioning mechanism can set the relative positions between the second kind superconductor (17) and the permanent magnet (14) on the side of the shaft (2), and the superconductive bearing (4) can be operated efficiently by setting suitably the relative positions. Breakage of the shaft (2) and components near the shaft (2), when the superconductor (17) of the superconductive bearing (4) changes to a normal conductor, can be prevented by the touchdown bearing (21).

摘要： A solid film (5) of a fluorine-containing polyurethane polymer is formed on at least one of the constituent elements (inner and outer races (1 and 2), rolling member (3) and retainer (4)) of a rolling-contact bearing (A). The molecules of the solid film (5) of the fluorine-containing polyurethane polymer have urethane bonds, and form a three-dimensional reticular structure. Therefore, the film is unlikely to separate, peel off or wear, the occurrence of the dust can be restricted, and lubrication property can be improved.

摘要： This invention relates to grease for roller bearings which contains poly- alpha -olefin synthetic oil or diphenylether synthetic oil, urea thickening agent, and organic antimony compound or organic molybdenum compound; and a roller bearing in which this grease is sealed. The organic antimony compound or organic molybdenum compound reacts with the rolling surfaces of the inner and outer races and the surfaces of rolling elements in the bearing to form compound films which contribute to the reduction of the tangential force, and to prevent the generation of an excessively large tangential force during the high-speed rotation of a rotary part. This enables the lifetime of a roller bearing, which is used, especially, under severe conditions, to be prolonged.

摘要： A variable diameter pulley comprises a pair of pulley main bodies (18, 19) connected to a rotating shaft (15), and a power transmission ring (20) interposed between the pulley main bodies. A belt (2) is passed around an outer periphery of the power transmission ring (20). The power transmission ring (20) is made eccentric relative to an axis (15a) of the rotating shaft (15) so as to be varied in its contact diameter (D). Both pulley main bodies (18, 19) are rotatable together and relatively movable in an axial direction. Both pulley main bodies (18, 19) are biased by an elastic member (22) to move toward each other. The respective pulley main bodies (18, 19) are threadedly connected to the rotating shaft (15) by a torque cam mechanism (T) composed of a pair of thread connection mechanisms, which are inversely threaded to each other. Torque for effecting rotation of the respective pulley main bodies (18, 19) relative to the rotating shaft (15) is converted into a force, which causes both pulley main bodies (18, 19) to approach each other in equal amounts of stroke.
