Abstract (en)
[origin: WO2005121731A1] The invention relates to a bearing, comprising at least one system for determining the amplitude (A) of pseudo-sinusoidal deformations of a region (7) of the fixed ring (1), generated on rotation, the system for determination comprising two stress gauges (8), a measuring device (9), for the two signals (V), which are respectively a function of the variations over time of the signals provided by each gauge (8) on rotation, said device forming, by combination of the signals Vi, two signals which are respectively the SIN and COS of the same angle with the same amplitude, said amplitude being a function of A and a device (10) for calculation of the amplitude A of the deformations in the region (7) as a function of time, said device being embodied to calculate the formula SIN<2> + COS<2> such as to give the amplitude A.
