Title (EN) PULLEY TENSIONER
(FR) TENDEUR DE POULIE
Abstract:
(EN) A pulley tensioner (10) for applying torque or tension to a pulley (14) is disclosed which includes a spring system (16) configured to at least partially encircle the periphery (18) of the pulley (14). The spring system (16) is anchored to the pulley housing (12) or some other fixed location. The spring system (16) is made up of one or more coil springs (28, 30, 32) which are wrapped at least partially around the periphery (18) of the pulley (14). Where multiple springs are used, preferably each spring has a different spring constant and length. This allows the operator to select the desired tension depending on the operating parameters of the printer (40). The applied tension may be further modified/tuned by using an additional spring member to anchor the spring system (16) to the pulley housing (12) or some other fixed location.
(FR) Cette invention concerne un tendeur (10) de poulie qui sert à appliquer un couple ou une tension sur une poulie (14), ce tendeur comprenant un système (16) de ressort configuré pour entourer au moins partiellement la périphérie (18) de la poulie (14). Le système (16) de ressort est fixé sur le carter (12) de la poulie ou à un autre endroit fixe. Le système (16) de ressort est constitué d'un ou plusieurs ressorts hélicoïdaux (28, 30, 32) qui sont entourés au moins partiellement autour de la périphérie (18) de la poulie (14). Lorsqu'on utilise plusieurs ressorts, chaque ressort présente de préférence une longueur et une constante d'élasticité différentes. Ceci permet à l'utilisateur de sélectionner la tension désirée en fonction des paramètres de fonctionnement (14). La tension appliquée peut en outre être modifiée/ajustée à l'aide d'un élément de ressort supplémentaire qui permet de fixer le système (16) de ressort sur le carter de la poulie ou à un autre endroit fixe.
