DISPOSITIF ET PROCEDE DE PROTECTION MECANIQUE

摘要

A device and method for providing mechanical protection, and in particular to a mechanical protection device including a transmission shaft with a resonant frequency in bending that corresponds to a predetermined rotary overspeed of the transmission shaft, the transmission shaft being insufficiently damped to avoid breakage of the transmission shaft as a result of the resonance in bending. In the mechanical protection method, the transmission shaft breaks as a result of this resonance in bending.
