Abstract

"cavilha anti-deformação de filetes" é provido uma cavilha anti-deformação de filetes que ele próprio impede deformação dos filetes sem que seja necessário que uma 5 porção piloto corrija sua postura. a cavilha é atarraxada em um parafuso fêmea com um diâmetro nominal de um diâmetro interno d1• na ponta de uma parte de filete regular 11 formada em uma haste da cavilha, uma parte de filete de pequeno diâmetro 12 é formada por um passo ou mais, a parte de filete de pequeno diâmetro tendo um diâmetro externo d que é maior que o 1 o diâmetro interno d1 do parafuso fêmea e menor que (d+d1)/2. quando a cavilha é atarraxada obliquamente no parafuso fêmea, a parte do filete de diâmetro 12 entra em contato com o parafuso fêmea em um ponto, mas a cavilha pode girar em tomo do ponto. assim, a ocorrência de deformação dos filetes é impedida.
