System for determining at least one defect of a bearing and associated method

A bearing comprising:

• a first ring, a second ring capable of rotating concentrically relative to one another, and
• a system for determining at least one defect of a bearing providing a first ring and a second ring capable of rotating concentrically relative to one another, measuring means for measuring first and second differential distances between the first ring and the second ring when the first ring is rotating relative to the second ring and for measuring the relative angular position of the first and second rings, during a predefined duration, storing means for storing each measured differential distance according to the relative angular position of the first and second rings and a value of a temporal variable indicative of the evolution of the predefined duration, determining means for determining a temporal profile of a radial relative displacement between the first and second rings, and a second temporal profile of an axial relative displacement between the first and second rings according to the stored measured differential distances by the storing means, and identifying means for identifying a defect of the bearing from the temporal profile.
