Rolling bearing () comprising an inner ring (), an outer ring (), at least one row of rolling elements which are arranged between raceways formed on the rings () and a ring gear () that has a circumference of less than 360&#xb0; and is fixed to one of the rings (). The ring gear () is formed of a single gear segment () which has a circumference substantially equal to the circumference of the ring gear () and is provided on its inner or outer peripheral surface with a plurality of meshing means () and fixed only to one of either the inner or outer rings () of the rolling bearing ().

Rolling bearing, notably for ship's propeller or for wind turbine

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

The roller bearing comprises an inner ring, an outer ring, at least one row of rolling elements which are arranged between the rings in order to form an axial thrust which can transmit axial forces, and a row of rolling elements arranged between the rings in order to form a radial thrust which can transmit radial forces. The inner ring comprises an annular groove which extends towards the interior from an outer surface of the ring, and forms a raceway for the rolling elements of the radial thrust.
