Abstract

"ACIONAMENTO ROSCADO DE ESFERAS". A presente invenção refere-se a um acionamento roscado de esferas com uma porca do fuso (2) disposta em um fuso (1), bem como, com esferas (3) que estão dispostas, podendo rolar em uma pista de rosca (4), sendo que, a pista de rosca (4) é formada por uma ranhura da rosca (5) executada no fuso (1), e por uma ranhura da rosca (5) executada na porca do fuso (2), e com, pelo menos, uma peça de desvio (8) disposta em uma recepção (7) da porca do fuso (2), que apresenta um canal de desvio (9) para o retorno das esferas (3), respectivamente, de uma extremidade de saída (10) para uma extremidade de entrada, pelo menos, de um filete (12) comum da pista de rosca (4), sendo que, a peça de desvio (8) é composta de duas peças de desvio parcial (13, 14), sendo que um plano de divisão divide longitudinalmente o canal de desvio (9).
