Transmission of a protection against overloads, destiny in particular to cause planes a coal and the like

摘要

The invention relates to a transmission, a protection against overloads. / p & & p & it comprises a measuring unit removable carrying an arrangement of gauges strain, which can be deformed elastically by the transmission of forces in the gear train, and an electronic control device which uncoupled, in the event of overload, a clutch separating the output shaft of the transmission of its input. According to the invention, the measuring member is constituted by a shaft of the measurement 33 placed on the inside of a transmission shaft, then its output shaft 2, connected in removable manner to that - latter, being integral in rotation and which can be removed by the end of the transmission shaft, at the state uncoupled. The shaft of the measurement is subjected to torsional stresses, is then in two parts, so that only the part of the shaft carrying the arrangement of the measuring gauges strain 55 must be replaced in the case of need.
