Abstract
The present invention relates to a device () for monitoring the degradation of rolling bearings () in a rotating machine () comprising at least two rolling bearings () each having two concentric rings (-) rotating relative to each other, at least one ring () of each bearing () being rotationally connected to a ring () of another bearing (). The device () comprises a member () for measuring the speed of rotation (ω) of the rotationally connected rings (), and data processing means suitable for detecting a variation in the speed of rotation (ω) of the rotationally connected rings (), which variation is representative of degradation of a bearing ().
