The roller bearing which possesses the difference of rigidity in the territory where it can have the deformation measurement equipment

摘要

The bearing has a fixed outer body (1) comprising an outer surface (3) that is elastically deformable by efforts induced by the passage of rolling bodies i.e. balls, during the rotation of a rotating body. The surface has an instrumented zone (4) on which a measurement gauge for measuring the deformations is associated. The zone is circumferentially surrounded on both sides by a non instrumented zone (5), where the rigidity of the zone (4) is greater than that of the zone (5). The surface has a flange (6) comprising a fixation orifice (7) forming a fixation unit of the bearing.
