<p>The invention concerns a neutral point setting device for the rotating ring of a roller bearing (5) provided with an inner ring (6) and an outer ring (7), one of the rings being integral with a fixed element (9) and the other ring being integral with a rotating element (1). The return device comprises springs designed to apply a return torque on the rotating ring to return it to the neutral point and means for limiting in two directions the rotation of the rotating ring. The device comprises a plate (19) mounted rotatable relative to the fixed element and two helical springs, a first spring (23) being arranged on one side of the plate (19) and fixed thereon by its internal end, a second spring (25) being arranged on the other side of the plate (19) and fixed by its internal end on the fixed element, the external end of the first spring (23) being linked, in a first direction, to the rotation of the rotating ring and the external end of the second spring (25) being linked, in a second direction opposite to the first, to the rotation of the plate (19), said device having a diameter not greater than the bore of the inner ring.</p> |
