    摘要： A multipoint contact ball bearing in constructed to prevent damage to rolling surfaces of the balls and to ensure durability while maintaining radial load capacity. An inner raceway has a complex curved surface including a pair of side surface sections having a generating line shape with a radius of curvature larger than 50% of the ball diameter, and an inner raceway bottom section connecting inside end edges in the width direction of the side surface sections. The inner raceway bottom section is a concave curved surface having a generating line shape with a radius of curvature less than 50% of the ball diameter. The edges of both sides in the width direction of the inner raceway bottom section and the inside end edges of the inner raceway side surface sections are smoothly continuous, and finishing is performed on the inner raceway bottom section and the inner raceway side surface sections.

    摘要： A cylindrical sliding bearing 1 can rotatably support a rotational shaft by a sliding surface 4 (inner circumferential surface). A crowning 5 having a sloped surface is formed at both ends of the sliding surface 4 in the axial direction. The crowning 5 includes a first crowning 3A formed of a sloped surface of a lining layer 3 and a second crowning 2A formed of a sloped surface of a back metal 2 positioned on the lower side of the first crowning. Unlike a conventional sliding bearing, the back metal 2 where the crowning 5 is positioned is provided as a sloped surface (2A). As compared with conventional bearings, the crowning 5 can be prevented from being unevenly brought into contact with the rotational shaft.

    摘要： The present invention relates to a delivery pump, in particular for delivering diesel fuel into a high-pressure accumulator. The pump has a housing and a drive shaft which is accommodated in the latter and is mounted by at least one sliding bearing arrangement such that it can rotate about a drive shaft axis. The sliding bearing arrangement is formed by a bearing bore and a bearing shaft section which extends through the latter. The sliding bearing arrangement has a bearing play which extends in the radial direction between the bearing shaft section and the bearing bore and has a smaller value in the bearing center than at least one bearing edge. A delivery pump for delivering diesel fuel is therefore provided which has a low-wear sliding bearing arrangement.
