(54) Title (EN): TORQUE LIMITER HAVING OVER-SPEED PROTECTION
(54) Title (FR): LIMITEUR DE COUPLE DE PROTECTION CONTRE LA SURVITESSE

(57) Abstract:
(EN): An apparatus for connecting a rotational drive member to a rotational driven member brakes rotation when either the torque transmitted between the members exceeds a predetermined torque limit or the rotational speed of the drive member exceeds a predetermined rotational speed limit. The apparatus includes a torque limiter configured to actuate a braking mechanism or disconnect transmission when the torque limit is exceeded, and an over-speed governor configured to trigger the torque limiter when the rotational speed of the input element exceeds the rotational speed limit. The over-speed governor may trigger the torque limiter by reducing the torque limit of the torque limiter, or by introducing rotational drag in the apparatus to increase transmitted torque.
(FR): Dans cette présente invention, un appareil pour relier un élément d'entraînement rotatif à un élément entraîné en rotation freine la rotation lorsque le couple transmis entre les éléments dépasse une limite de couple prédéterminée ou que la vitesse de rotation de l'élément d'entraînement dépasse une limite de vitesse de rotation prédéterminée. L'appareil comprend un limiteur de couple configuré pour actionner un mécanisme de freinage ou une transmission de déconnexion lorsque la limite de couple est dépassée, et un régulateur de survitesse configuré pour déclencher le limiteur de couple lorsque la vitesse de rotation de l'élément d'entrée dépasse la limite de vitesse de rotation. Le régulateur de survitesse peut déclencher le limiteur de couple en réduisant la limite de couple du limiteur de couple, ou en introduisant une traînée de rotation dans l'appareil pour augmenter le couple transmis.
