Abstract
Rolling bearing (1) comprising an inner ring (3), an outer ring (2), at least one row of rolling elements which are arranged between raceways made on the rings (2, 3) and an ring gear (6) fixed to one of the rings (2). The ring gear (6) is formed of at least two independent gear segments (7, 8, 9, 10, 11, 12) which are each provided on their inner or outer peripheral surface with a plurality of meshing means (7b, 8b, 9b, 10b, 11b, 12b) and fixed only to one of either the inner or outer rings (3) of the rolling bearing (1), the circumference of the ring gear (6, 20) being substantially equal to the circumference of the combination of the independent gear segments.
