Abstract:
(EN) A tensioner comprising a base, a shaft press fit into the base, a pivot arm journalled to the shaft, the pivot arm having a first frustoconical portion and a frustoconical bushing disposed thereon, a pulley journalled to the pivot arm, a torsion spring engaged between the base and the pivot arm for biasing the pivot arm, a seal disposed between the base and pivot arm on the shaft, the shaft comprising a second frustoconical portion describing an apex angle ?, and the torsion spring applying an axial spring force to the pivot arm such that the first frustoconical portion is in pressing engagement with the second frustoconical portion.
(FR) L'invention concerne un tendeur comprenant une base, un arbre inséré de force dans la base, un bras de pivot tourillonné sur l'arbre, ce bras de pivot comportant une première partie tronconique et une douille tronconique disposée sur celle-ci, une poulie tourillonnée sur le bras de pivot, un ressort de torsion mis en prise entre la base et le bras de pivot afin de solliciter ce dernier, un joint disposé entre la base et le bras de pivot sur l'arbre, l'arbre comportant une deuxième partie tronconique décrivant un angle de sommet, et le ressort de torsion exerçant une force de ressort axiale sur le bras de pivot de sorte que la première partie tronconique soit en contact de pression avec la deuxième partie tronconique.
