(FR) TENDEUR ET PROCÉDÉ
Abstract:
(EN) A tensioner comprising a base defining a hole, the hole having a center C, the hole having a diameter sufficient to receive a driven pulley, a rotary arm engaged with the base by a retaining member connected to the base, the rotary arm rotatable about the center C, a pivot arm mounted to the rotary arm on a pivot, the pivot offset from center C, a first pulley journalled to the rotary arm, a second pulley journalled to the pivot arm, a torsion spring engaged between the rotary arm and the pivot arm for biasing the second pulley toward the first pulley, a damping member frictionally engaged between the base and the rotary arm, and the rotary arm defining a portion for receiving a first pulley fastener whereby a first pulley position is adjustable.
(FR) L'invention concerne un tendeur, lequel tendeur comprend une base définissant un trou, le trou ayant un centre C, le trou ayant un diamètre suffisant pour recevoir une poulie entraînée, un bras rotatif venant en prise avec la base à l'aide d'un élément de maintien relié à la base, le bras rotatif pouvant tourner autour du centre C, un bras de pivot monté sur le bras rotatif sur un pivot, le pivot étant décalé par rapport au centre C, une première poulie tourillonnée sur le bras rotatif, une seconde poulie tourillonnée sur le bras de pivot, un ressort de torsion venant en prise entre le bras rotatif et le bras de pivot de façon à solliciter la seconde poulie vers la première poulie, un élément d'amortissement venant en prise par frottement entre la base et le bras rotatif, et le bras rotatif définissant une partie pour recevoir un premier élément de fixation de poulie par lequel une première position de poulie est ajustable.
