Claim:
1. A rolling bearing comprising: an inner ring having a first axial end, a second axial end, and a cylindrical inner surface, an outer ring, at least one row of rolling elements disposed between the inner and outer rings, and a ring gear fixed to the cylindrical inner surface of the inner ring, wherein the ring gear is formed of at least two independent gear segments, each of the at least two independent gear segments, when viewed in axial cross-section, having first and second axial sections adjacently located side-by-side so as not to radially overlap, the first axial section defining a first gear segment inner radius, the second axial section having first and second radially extending surfaces between which are located a plurality of teeth such that the plurality of teeth are located entirely on the second axial section and configured to extend radially inwardly therefrom, the plurality of teeth defining a dedendum circle forming a second gear segment inner radius, the first gear segment inner radius being greater than the second gear segment inner radius, the ring gear being completely radially overlapped by the inner ring such that, when viewed in axial cross-section, no portion of the ring gear extends axially past either of the first axial end or the second axial end of the inner ring in a direction away from the at least one row of rolling elements, a maximum outer diameter of the ring gear is equal to or less than a diameter of the cylindrical inner surface of the inner ring, and wherein the circumference of the ring gear is substantially equal to the circumference of the combination of the at least two independent gear segments.
