Title (EN) MECHANICAL PROTECTION METHOD AND DEVICE
(FR) DISPOSITIF ET PROCEDE DE PROTECTION MECANIQUE.
Abstract: front page image
(EN)The invention relates to the field of mechanical protection methods and devices, and in particular relates to a mechanical protection device comprising a transmission shaft (1) with a resonant frequency in bending that corresponds to a predetermined overspeed in the rotation of the transmission shaft (1) that is not damped enough to avoid breakage of the transmission shaft (1) as a result of said bending resonance, and to a mechanical protection method involving the breakage of the transmission shaft (1) as a result of this bending resonance.
(FR)L'invention concerne le domaine des dispositifs et procédés de protection mécanique, et en particulier un dispositif de protection mécanique comportant un arbre de transmission (1) avec une fréquence de résonance en flexion correspondant à une survitesse de rotation prédéterminée de l'arbre de transmission (1), insuffisamment amorti pour éviter une rupture de l'arbre de transmission (1) suite à ladite résonance en flexion, et un procédé de protection mécanique, comportant la rupture de l'arbre de transmission (1) par cette résonance en flexion.
