Abstract
L'invention concerne les mécanismes de rappel élastique. Elle se rapporte à un mécanisme dans lequel une came 30 tourne lors de la commande d'un dispositif et repousse alors un toucheau 50, formé par un galet, qui comprime un ressort. Lorsque la force de rotation la came 30 est supprimée, la force du ressort provoque le rappel de la came dans la position initiale. Le profil de la came est calculé afin que le couple appliqué corresponde aux caractéristiques voulues. Application à la commande automatique de dispositifs rotatifs en cas de panne.
