Method for assembling a bearing ring with a mechanical element

摘要

The process for assembling two elements constituted of a part from a bearing ring equipped with a path and of another part from a mechanical element, comprises forming a first element to present a deformable annular edge defining a reference axis, forming a second element to present a maintenance surface, annealing a set of the ring for conferring a ductility and an elasticity on the edge, thermally or thermochemically treating the element at a level of the rotational path to introduce residual constraint of localized compression and to increase the hardness of the rotational path. The process for assembling two elements constituted of a part from a bearing ring equipped with a path and of another part from a mechanical element, comprises forming a first element to present a deformable annular edge defining a reference axis, forming a second element to present a maintenance surface, annealing a set of the ring for conferring a ductility and an elasticity on the edge, thermally or thermochemically treating the element at a level of the rotational path to introduce residual constraint of localized compression and to increase the hardness of the rotational path, mounting the first ring with a second ring on a tower, globally crushing the ring, and spinning the annular edge of the first part. The second element is rotated in a transverse plane with the first element by friction. A tool is arranged for rolling the second element compared to the first element. The first element is fixed to a mandrel to rotate the two elements around the reference axis. The rotating tool radially leads to an initial position of contact just opposite to a final position of contact with a linear speed corresponding to a progression of 0.2 mm per turn. The mandrel is turned with a speed lower than 700 turns per minute during spinning. A rolling body is interposed between the two rings. The deformable edge is produced by a non-fibrous ductile frit material, which is then compressed by the rotating tool. An independent claim is included for a set of two elements.
