Abstract

"ESTICADOR DE CORREIA AUTOMáTICO". A invenção refere-se a um esticador de correia automático, com uma parte de base que é conectada com uma parte de tensionamento giratoriamente em torno de um eixo geométrico de rotação em comum, uma mola de helicoidal que é ligada com a parte de base e a parte de tensionamento, e uma bucha de envolvimento que é envolta pelo menos por regiões por regiões pela mola helicoidal com uma força de torção radial. Para que o esticador de correia assegure, com uma construção simples, um bom amortecimento e boa propriedade de amortecimento, tanto quanto possível sobre toda a vida útil do esticador de correia, bem como possa ser usado universalmente, é proposto que o material da bucha de envolvimento contenha material plástico reforçado.
