    Abstract: In a bearing apparatus for a wheel in which a hub, a constant velocity universal joint and double rows of bearings are united and one inner raceway of double rows of inner raceways, of the double rows of bearings is integrally formed with an outer joint member of the constant velocity universal joint, a stem portion of the outer joint member is fitted to the hub, an unevenness portion is formed on an inner peripheral surface of the hub or an outer peripheral surface of the stem portion or both thereof, and the hub and the outer joint member are plastically connected by expanding the hollow stem portion from an inner diameter side to an outer diameter side by caulking. Accordingly, the fitted portions of the hub and the outer joint member are prevented from being loosened.

    Abstract: A rolling bearing unit comprises a shaft body, an inner ring mounted on the shaft body, an outer ring concentric with the inner ring, and a plurality of balls between the inner ring and the outer ring. A caulking portion to be caulked onto the outer end face of the inner ring is formed on the shaft body. A pre-load is applied to the balls to fix the inner ring to the shaft body. The retained austenite amount of an edge of the inner ring in the vicinity of the caulking portion is set between 3% or more and 20% or less.

    Abstract: A wheel assembly includes a hub and bearing unit in which an annular hub has an axial cylindrical seat with an outer ring of a bearing fitted thereto with radial interference. The ring is locked axially on the hub between a pair of annular rims which project radially outwardly from the outer cylindrical surface of the ring and have been cold-deformed so as to engage two opposite surfaces of the hub. The hub also has an outer radial flange for fixing a brake rotor which in turn has an inner radial flange arranged substantially in the same plane as the flange. The brake rotor is locked axially on the hub by at least one cold-deformed annular rim which projects radially outwardly from the flange on the hub so as to engage a respective one of two radial surfaces of the flange.

    Abstract translation: 轮组件包括轮毂和轴承单元，其中环形轮毂具有轴向圆柱形座，其轴承的外圈具有径向干涉。 环在轮毂上轴向锁定在一对环形轮圈之间，该环形轮圈从环的外圆柱形表面径向向外突出，并且已被冷变形，从而与轮毂的两个相对的表面接合。 轮毂还具有用于固定制动转子的外径向凸缘，该制动转子又具有大体上与法兰在同一平面内布置的内径向凸缘。 制动转子通过至少一个冷却变形的环形边缘轴向地锁定在轮毂上，该环形边缘从轮毂上的凸缘径向向外突出，以便接合凸缘的两个径向表面中的相应一个。

    Abstract: The roller for a running-gear mechanism or for a roller battery in a cableway system has a roller body formed with a central bore in which a bearing is located. The roller is provided with two flanged disks and a virtually non-elastic annular support for a cable of the cableway system between the disks. One or both of the flanged disks is fastened releasably on the roller body in that the outer circumferential surface of the roller body is formed, in the region of the abutting end surface of said roller body, with at least one encircling groove for a spring ring or the like that holds the removable flanged disk on the roller body. A resilient insert is arranged between the support and at least one of the flanged disks.

    Abstract: A developing roller has a roller core, an electrically conductive layer provided on a circumferential surface of the roller core, and a covering layer provided on the outer circumferential surface of the conductive layer. The covering layer is formed by subjecting a reaction mixture containing a fluorine-containing polyol, a reactive silicone oil having an active hydrogen, and an isocyanate compound, to a reaction condition for reacting the fluorine-containing polyol and the reactive silicone oil with the isocyanate compound.
