Abstract:
An assembly comprising:a bearing (1) comprising a fixed raceway (2) intended to be associated with a fixed structure, a rotating raceway (3) intended to be associated with a rotating member (6); and a mechanical interface (5) associated with the said fixed raceway (2) by means of association means (7), this interface (5) being intended to be interposed between the fixed raceway (2) of the bearing (1) and the fixed structure, the said interface (5) comprising: first means (8) of fixing to the fixed structure; second means (9) of fixing a device (10) intended to apply a force to the rotating member (6); and at least one elastic deformation zone (29-33) able to be deformed under the action of forces exerted on the said assembly, at least one sensor (38) able to measure the said forces causing deformation of said elastic deformation zone (29-33); characterised in that the interface (5) comprises two flat faces (23, 24) extending radially and connected together by a circumferential face (25), a bore (27) with a diameter substantially greater than the outside diameter of the fixed raceway (2) being formed in the said interface (5); characterised in that the interface (5) comprises second radial projections (43, 44) forming second means (9) of fixing to the bearing the device (10) intended to apply a force to a rotating part (6) associated with the rotating raceway (3), the projections (43, 44) each comprising a base zone (46) and an end zone (47); characterised in that the said second projections (43, 44) comprise axial holes (45) for fixing the said device (10) by screwing, located in the end zone (47), at least one sensor (38) being disposed on or in the vicinity of the base zone (46), this forming an elastic deformation zone (32, 33); characterised in that two sensors (38) are disposed on the circumferential face (25), on each side of each second projection (43, 44).
