DETECTION SYSTEM AND METHOD FOR DETECTING WEAR OF A DEVICE WITH BALL-AND-SOCKET JOINT FOR CONNECTING A CONNECTING ROD, ROTOR ASSEMBLY AND AIRCRAFT

摘要

The present invention relates to a detection system (30) for detecting wear of a ball joint device (25) of a pitch rod (20). This detection system (30) comprises at least one measuring assembly (31) having at least one strain gauge (33, 35, 36, 38) to be placed on said pitch rod (20), said detection system (30 ) comprising at least one electrical processing circuit (40) connected to at least one said strain gauge (33, 35, 36, 38) and to at least one source of electrical energy (50), said electrical processing circuit ( 40) being configured to generate a measuring signal varying as a function of a deformation of said at least one deformation gauge (33, 35, 36, 38) and as a function of said wear.
