Patent ID: 8777800

Claim:
A mechanical assembly provided with a sun gear together with a plurality of planet gears cooperable with said sun gear, the mechanical assembly having a planet carrier carrying each planet gear, each planet gear comprising a toothed body and rolling connection means interposed between a bottom portion of a pin of the planet gear and said body, each pin having a projecting top portion secured to said planet carrier, each body being movable in rotation firstly about its own first axis of rotation and secondly about a second axis of rotation of the planet carrier, said mechanical assembly including an outer annulus having an inner periphery that co-operates with each planet gear, each planet gear being movable in an annular space situated between said inner periphery and said sun gear, each planet gear including a vibration sensor forming part of monitoring means for monitoring for a structural anomaly, said monitoring means being provided with a control member configured to communicate with each vibration sensor in order to receive a measurement signal from each vibration sensor in order to enable anomaly monitoring to be performed, wherein said monitoring means includes at least one antenna placed on an outer periphery of said annulus, said control member being configured to communicate with at least one of the vibration sensors via said at least one antenna; wherein said monitoring means is configured to, after acquiring a measurement signal, verify integrity of the signal in order to validate it, and wherein said monitoring means is further configured to eliminate each measurement signal of non-validated integrity.
