INSTRUMENTED ROLLER BEARING

摘要

The invention concerns an instrumented roller bearing device comprising at least a rotatable ring (4), a non-rotatable ring (2), at least a row of rolling elements (6) arranged between the raceways of the rotatable ring (4) and the non-rotatable ring (2), and a data sensor assembly comprising a non-rotatable sensor unit (22). The device comprises a rotatable encoder (21) designed to co-operate with at least a detection member borne by the sensor unit, the sensor unit (22) comprising an annular portion (34) radially arranged between the non-rotatable ring (2) and a support such that said annular portion (34) forms an interface between the non-rotatable ring (2) and the support to compensate radial dimensional variations.
