Abstract

"DISPOSITIVO TENSIONADOR PARA CORREIAS". O dispositivo tensionador (1) compreende uma placa de suporte (2) anexada a um pivó (3) que define um primeiro eixo (A); um elemento tubular intermediário (15) acomodando dito pivó (3) e capaz de girar em torno de dito primeiro eixo (A); uma polia (4) suportada por dito elemento tubular (15), circundando dito pivó (3) e capaz de girar em torno de um segundo eixo (B) que não é coincidente com dito primeiro eixo (A); e um elemento elástico (27) interposto entre dito pivó (3) e dito elemento tubular intermediário (15) de modo a impelir elasticamente dito elemento tubular intermediário (3) contra dita correia (5). Para garantir um elevado grau de perpendicularidade entre o pivó e a placa de suporte e, portanto, um engate preciso entre o dispositivo tensionador (1) e a correia (5), a placa de suporte (2) e o pivó (3) são formados integralmente em uma única peça.
