BEARING WITH A CLEARANCE MEASUREMENT DEVICE

The invention relates to a bearing with a clearance measurement device, comprising a first ring (2) with a first face (3); a second ring (4) with a second face (5) opposite the first face (3), a distance (d S) being defined between both faces (3, 5); one or more rolling elements (6) arranged between...

Zusammenfassung:	The invention relates to a bearing with a clearance measurement device, comprising a first ring (2) with a first face (3); a second ring (4) with a second face (5) opposite the first face (3), a distance (d S) being defined between both faces (3, 5); one or more rolling elements (6) arranged between the first ring (2) and the second ring (4), which allow relative movement between both rings (2, 4); and an eddy current sensor (10) configured for measuring the distance (d S) between the first face (3) and the second face (5). Said sensor (10) comprises an inductive module (20) having a flat configuration formed in a printed circuit board (21), integrating at least one coil (22); said inductive module (20) being arranged on one of the faces (3, 5) to allow measuring the distance (d S) with respect to the opposite face (3, 5). L'invention concerne un palier doté d'un dispositif de mesure d'espace, comprenant une première bague (2) pourvue d'une première face (3) ; une seconde bague (4) pourvue d'une seconde face (5) en regard de la première face (3), une distance (d S) étant définie entre les deux faces (3, 5) ; un ou plusieurs éléments roulants (6) agencés entre la première bague (2) et la seconde bague (4), qui permettent un mouvement relatif entre les deux bagues (2, 4) ; et un capteur à courants de Foucault (10) configuré pour mesurer la distance (d S) entre la première face (3) et la seconde face (5). Ledit capteur (10) comprend un module inductif (20) ayant une configuration plate formé dans une carte de circuit imprimé (21), intégrant au moins une bobine (22) ; ledit module inductif (20) étant agencé sur une des faces (3, 5) pour permettre la mesure de la distance (d S) par rapport à la face opposée (3, 5).
