Abstract

a presente invenção diz respeito a uma estrutura de polia (1) equipada com um corpo rotativo externo (2), um corpo rotativo interno (3) e uma mola helicoidal (4), a dita estrutura de polia 1 caracterizada em que uma seção transversal do arame de mola da mola helicoidal (4) ao longo de uma direção se estendendo ao longo do eixo de rotação e paralela ao eixo de rotação é uma forma trapezoidal, a dimensão ti [mm] de uma parte de lado de diâmetro interno na direção de eixo de rotação na seção transversal é maior que a dimensão to [mm] de uma parte de lado de diâmetro externo na direção de eixo de rotação na seção transversal, e quando o número de voltas da mola helicoidal (4) é n, a expressão (1) é satisfeita. n × (ti - to) / 2 < 1 ... (1).
