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 formed on the rings (2, 3) and a ring gear (6) that has a circumference of less than 360° and is fixed to one of the rings (2). The ring gear (6) is formed of a single gear segment (7) which has a circumference substantially equal to the circumference of the ring gear (6) and is provided on its inner or outer peripheral surface with a plurality of meshing means (7b) and fixed only to one of either the inner or outer rings (3) of the rolling bearing (1).

A rolling bearing (1) comprising:
- an inner ring (3),
- an outer ring (2),
- at least one row of rolling elements (4) disposed between raceways (2c, 3c) formed on the rings (2, 3), and
- a ring gear (6, 10) having a circumference less than 360° and fixed to one of the rings (2, 3), wherein
- the ring gear (6, 10) is formed by a single gear segment (7, 11) having a circumference substantially equal to the circumference of the ring gear (6, 10) and including a plurality of meshing means (7b, 11b) disposed on one of an inner and outer peripheral surface and fixed to one of the inner or outer rings (3, 2).
A wind turbine comprising:
- a nacelle, mounted on a mast and enclosing a generator intended to produce electrical energy,
- a rotor provided with a hub supporting at least two blades, and
- a rolling bearing (1) mounted between the hub and a blade, the rolling bearing providing;
- an inner ring (3),
- an outer ring (2),
- at least one row of rolling elements (4) disposed between raceways (2c, 3c) formed on the rings (2, 3), and
- a ring gear (6, 10) having a circumference less than 360° and fixed to one of the rings (2, 3), wherein
- the ring gear (6, 10) is formed by a single gear segment (7, 11) having a circumference substantially equal to the circumference of the ring gear (6, 10) and including a plurality of meshing means (7b, 11b) disposed on one of an inner and outer peripheral surface and fixed to one of the inner or outer rings (3, 2).
