  • Patent number: 9352523
    Abstract: A green tire of a pneumatic tire, including a cylindrical annular structure, an unvulcanized rubber layer, which will become a tread portion, provided along a circumferential direction of the annular structure on an outer side of the annular structure, and a carcass portion including fibers covered with rubber, provided on at least both sides in the width direction of a cylindrical structure including the annular structure and the unvulcanized rubber layer, is disposed in a vulcanization mold. The vulcanization mold is split into the side plates and the sector at a position on the inner side in the width direction of the annular structure. Next, the bladder inside the green tire is pressurized after closing the side plates and prior to closing the sector. Then the sector is closed and vulcanization is started.

  • Publication number: 20120001510
    Abstract: The permanent magnet rotor is capable of making tolerance of attaching a magnet cover great, applying no stress to structural elements of the rotor, preventing the magnet cover from being damaged under an environment where thermal expansion and thermal contraction are repeated in response to temperature variation, and preventing scatter of magnets. The permanent magnet rotor of an inner rotor-type motor comprises: a rotor yoke; a plurality of permanent magnets being arranged on an outer circumferential face of the rotor yoke, the permanent magnets constituting a plurality of segments; and a ring-shaped magnet cover covering outer faces of the permanent magnets, the magnet cover being composed of a nonmagnetic material. An inner diameter of the magnet cover before covering the outer faces of the permanent magnets is smaller than an outer diameter of the circularly-arranged permanent magnets.

  • Patent number: 7911099
    Abstract: An outer rotor motor has a bearing housing with reduced machining and material costs, can be assembled with high accuracy, and has favorable durability. A bearing is attached to an inner circumferential surface of a housing main body that has been formed in a cylindrical shape by plastic deformation caused by press molding a metal matrix. At least one protruding surface is formed by plastic deformation so as to protrude further outward than the housing main body, and the stator core is attached to the outer circumference-side of the at least one protruding surface.
