Abstract

REDUTOR DE VELOCIDADE POR CORRENTE. A presente invenção refere-se a um mecanismo redutor mecânico de velocidade, que em alguns casos pode ser também multiplicador de velocidade, onde para cada estágio de redução ou multiplicação se usam duas engrenagens dispostas lateralmente e paralelamente entre si e com uma delas com movimento orbital proporcionado por um came excêntrico solidário ao elemento de entrada do redutor e a outra engrenagem posicionada no mesmo centro do elemento de entrada e a transmissão de torque entre as polias é feita através de uma corrente a qual envolve as duas polias.
