Abstract

Patente de Invenção: <B>"ENGATE RANDÈMICO DE DENTE DE ENGRENAGEM DE CORRENTE COM ENGRENAGEM ESCALONADA E ALìVIO DE RAIZ PARA PROVER CARACTERìSTICAS DE RUìDO MELHORADAS"<D>. Engrenagem de corrente de engate randómico (112, 114), compreendendo uma quantidade de primeiros dentes (150), cada um apresentando um primeiro flanco de engate e um primeiro flanco de desengate; uma quantidade de segundos dentes (152), cada um apresentando um segundo flanco de engate e um segundo flanco de desengate. Um dos primeiros flancos de engate (164) cooperando em conjunto com um dos referidos primeiros flancos de desengate ou com um dos segundos flancos de desengate mencionados (168) de um primeiro dente adjacente (166), a fim de definir um primeiro espaçamento de dente assimétrico (154) para receber um rolo (128), associado com a corrente (116). Este primeiro espaçamento de dente assimétrico (154) inclui uma primeira superfície da raiz (156) adaptada para entrar em contato com um rolo (128) durante a rotação da roda dentada (112, 114). Um dentre os segundos flancos de engate (184) cooperando em conjunto com um dentre os referidos primeiros flancos de desengate ou dentre os segundos flancos de desengate (188) do segundo dente adjacente (186) para definir um segundo espaçamento de dente assimétrico (158) para receber um rolo (128). O segundo espaçamento de dente assimétrico (158) incluindo uma segunda superfície da raiz (160), sendo espaçada de um rolo (128), de tal forma a definir um espaçamento (196) entre as mesmas, durante a rotação da roda dentada (112, 114).
