Abstract
a presente invenção se refere a uma estrutura de polias (1) equipada com um corpo rotativo externo (2), um corpo rotativo interno (3), e uma mola helicoidal (4) provida entre o corpo rotativo externo (2) e o corpo rotativo interno (3). a mola helicoidal (4) é configurada de modo a se submeter a uma deformação por torção em uma direção de expansão de diâmetro ou em uma direção de contração de diâmetro, desta maneira se encaixando no corpo rotativo externo (2) e no corpo rotativo interno (3) e transmitindo torque, e de modo a se submeter a uma deformação por torção no sentido oposto à direção na qual um torque é transmitido, deste modo entrando em um estado de desengate no qual a mola helicoidal desliza com o corpo rotativo externo (2) ou com o corpo rotativo interno (3), deste modo interrompendo a transmissão de torque. o número de enrolamentos da mola helicoidal (4) se encontra em uma faixa entre [m - 0.125] e m (ambas inclusive), sendo que m é um número natural.
