    摘要: The invention relates to a flanged bearing ring produced from a high carbon steel profile bar comprising at least one flash butt welded joint, where the bearing ring is provided with an inner peripheral surface and an outer peripheral surface and where one peripheral surface comprises a raceway for rolling elements, where the bearing ring further comprises a flange adapted for fixing the bearing ring to a mechanical member, where the flange protrudes from the bearing ring in a substantially radial direction. The invention further relates to a method for producing such a homogenous flanged bearing ring from a straight profile bar. The advantage of the invention is that a homogenous flanged bearing ring is obtained in a simple and cost-effective way.

    摘要: The invention relates to a method for the production of a flange sleeve especially for a sliding bearing. A strip of material is cut into lengths corresponding to the later periphery of the flange sleeve. The strip section thus arising is rolled to form a hollow cylindrical sleeve with an open butt joint and a collar is placed around one or two sides. The open butt joint is expanded in the region of the collar to form a V-shaped slit. One or several recesses are made in the region of the later open butt joint on one or two of the longitudinal edges of the strip section.

    摘要: The invention provides a bearing sleeve and method of forming a sleeve having at least one window whose edge boundary has a first apex region and a second apex region situated opposite one another in the sleeve longitudinal direction. In order to prevent chip formation when pressing the bearing sleeve into a bearing housing, it is provided that, in at least one apex region, the edge boundary forms an angle α≠90° with the sleeve longitudinal direction of the bearing sleeve.

    摘要: A spindle motor of small size, thin type, high reliability, and high performance suited to an information recording and reproducing apparatus is presented. Specifically, a rotary disk is composed by integrally forming a disk board, and a rotary shaft of spindle motor, and a bearing is composed by forming dynamic pressure generating grooves in the rotary shaft of the rotary disk. As a result, small size and thin structure are realized, surface deflection of the disk during rotation of the spindle motor, and its axial center deflection are substantially decreased, and moreover the recording density is enhanced, the number of constituent parts is curtailed, and the cost is saved.

    摘要: The invention relates to a method for the production of a flange sleeve (10) especially for a sliding bearing. A strip of material is cut into lengths corresponding to the later periphery of the flange sleeve. The strip section (14) thus arising is rolled to form a hollow cylindrical sleeve with an open butt joint (12) and a collar (20) is placed around one or two sides. The open butt joint is expanded in the region of the collar to form a V-shaped slit. One or several recesses (18a, 18b) are made in the region of the later open butt joint (12) on one or two of the longitudinal edges (16) of the strip section.
