Title (EN) BEARING, COMPRISING AN INNER RING, AN OUTER RING AND A SENSOR, AND SYSTEM, COMPRISING SUCH A BEARING
(FR) PALIER, COMPRENANT UNE BAGUE INTERNE, UNE BAGUE EXTERNE ET UN CAPTEUR, ET SYSTÈME COMPRENANT UN TEL PALIER
Abstract:
(EN) The invention relates to a bearing, comprising an inner ring (2) and an outer ring (4) rotatable relative to said inner ring (2), a sensor (6) for detecting a measured variable corresponding to a rotation of said outer ring (4) relative to said inner ring (2), whereat said sensor (6) comprises a stator (6.1) and a rotor (6.2). In order to provide a bearing with a more compact design, said sensor (6) is built as an inductive sensor (6) and said stator is torque-proof connected to said inner ring and said rotor is torque-proof connected to said outer ring or said stator (6.1) is torque- proof connected to said outer ring (4) and said rotor (6.2) is torque-proof connected to said inner ring (2). Furthermore, the invention relates to a system, comprising a torque-proof part and a rotating part rotatable relative to said torque-proof part and a bearing comprising an inner ring (2) and an outer ring (4).
(FR) L'invention concerne un palier, comprenant une bague interne (2) et une bague externe (4) pouvant tourner par rapport à ladite bague interne (2), un capteur (6) destiné à détecter une variable mesurée correspondant à une rotation de ladite bague externe (4) par rapport à ladite bague interne (2), ledit capteur (6) comprenant un stator (6.1) et un rotor (6.2). En vue d'obtenir un palier de conception plus compacte, ledit capteur (6) est réalisé sous la forme d'un capteur inductif (6) et ledit stator est relié solidaire en rotation à ladite bague interne et ledit rotor est relié solidaire en rotation à ladite bague externe ou encore ledit stator (6.1) est relié solidaire en rotation à ladite bague externe (4) et ledit rotor (6.2) est relié solidaire en rotation à ladite bague interne (2). L'invention concerne en outre un système comprenant une partie solidaire en rotation et une partie rotative pouvant tourner par rapport à ladite partie solidaire en rotation et un palier comprenant une bague interne (2) et une bague externe (4).
