Title (EN) EFFICIENT MECHANICAL RECTIFIER
(FR) REDRESSEUR MECANIQUE EFFICIENT
Abstract:
(EN) A mechanical rectifier (100, 200, 300, 400, 500) efficiently rectifies or converts alternative clockwise and counterclockwise rotation of a main handle (180) or other active driving element (660) into unidirectional rotation of a main shaft (102, 202, 302, 402, 502, 602). This mechanical rectifier is useful in manual tools such as a 'non-waste screwdriver', which eliminates the wasted hand motion inherent in all ordinary hand tools, and in energy-saving devices such as a wave-powered electrical generator. The basic mechanical rectifier includes a shaft, two driving elements (120, 124, 220, 224, 320, 324, 420, 424, 520, 524, 624), and a reversing mechanism (108, 208, 308, 408, 508) coupling the two driving elements so that they can only rotate in opposite directions.
(FR) Redresseur mécanique (100, 200, 300, 400, 500) qui redresse ou convertit la rotation alternativement horaire et anti-horaire d'une poignée principale (180) ou d'un autre élément d'entraînement actif (660) en rotation unidirectionnelle d'un arbre principal (102, 202, 302, 402, 502, 602). Ce redresseur mécanique est utile pour les outils à main tels que les 'tournevis sans perte', qui éliminent le mouvement perdu de la main inhérent à tous les outils à main ordinaires, et pour les dispositifs économiseurs d'énergie tels que les générateurs alimentés par l'énergie des vagues. Le redresseur mécanique de base comprend un arbre, deux éléments d'entraînement (120, 124, 220, 224, 320, 324, 420, 424, 520, 524, 624) et un mécanisme d'inversion (108, 208, 308, 408, 508), qui couple les éléments d'entraînement de façon qu'ils ne puissent tourner que dans les directions opposées.
