A DEFORMATION-SENSING BEARING HAVING FOUR STRESS GAUGES

摘要

The invention relates to a bearing comprising at least one system for determining the amplitude A of pseudo- sinusoidal deformations induced during rotation of a fixed ring (1) area (7), wherein said system comprises four stress gauges (8), a device for measuring four signals Vi based on time variations of a signal emitted by each gauge (8) and for forming two signals SIN and COS for the same angle and amplitude and a device for computing the time-dependent amplitude A of the area (7) deformations for calculating a SIN2 + COS2 expression in such a way that the amplitude A is derived therefrom. ® KIPO & WIPO 2007
