摘要： A wheel hub assembly with two rows of rolling elements has a central axis of rotation and inner raceway and outer raceways for each row of elements, the associated inner and outer raceways being axially displaced in accordance with a respective angle of contact and along a respective load line such that the assembly is capable of accommodating combined loading. The raceways of each row of rolling elements have osculation ratios which are defined by the ratio between the radius of curvature of the raceways and the outside diameters of the rolling elements of the associated row of rolling elements. The osculation ratios of a first one of the two rows of the rolling elements are different than the osculation ratios of a second one of the two rows of the rolling elements.

摘要： It is aimed to increase the rigidity of an angular contact ball bearing of the type in which each ball contacts at least one of the raceways at two points, improve the lubricating environment of the balls, reduce the weight of the bearing while maintaining wear resistance and rigidity of the balls, reduce the weight of the bearing while maintaining wear resistance of the balls, improve the radial rigidity and axial rigidity of the bearing in a balanced manner, or to supply a sufficient amount of lubricating oil into an internal area between the two contact points between each ball and the raceway.A counter portion 7 is formed. With each ball 6 in contact with the raceway at two points, a gap is present between the portion of the bearing ring at the bearing centerline C and each ball 6. The balls 6 may be ceramic balls. A coating for improving wear resistance may be applied to the balls. The contact angle of the contact point close to the bearing center line is set at 15 to 25°, while the contact angle of the contact point remote from the centerline C is set at 40 to 50°.

摘要： A four-point ball bearing includes: an inner ring and an outer ring defining raceway grooves, respectively. Each of the raceway grooves is constituted by two circular arcs different in curvature provided on opposite sides of a widthwise center of the raceway groove. A plurality of balls are arranged between the inner and outer rings so that the balls can roll. In at least one of the raceway grooves, a center of curvature of one of the circular arcs and a center of curvature of the other circular arc are displaced from each other at least in a radial direction so that spin is generated in each of the balls.
