Abstract

Patente de Invenção: <B>"óLEOS DE ENGRENAGEM PARA DESEMPENHO DE LIMPEZA"<D>. Providencia-se um óleo de engrenagem para desempenho de limpeza para uso em óleos de transmissão e lubrificantes de eixo. O óleo de engrenagem possui uma Viscosidade Brookfield a-12°C que varia de cerca de 1.000 a cerca de 150.000 cP, compreende um óleo de base tendo uma viscosidade cinemática a 100°C que varia de cerca de 4,0 a cerca de 41,0 cSt. Combinado com o óleo de base está preferivelmente um depressor do ponto de gotejamento do dispersante e/ou um aperfeiçoador do índice de viscosidade do dispersante. Em uma modalidade preferida adicional, o óleo de engrenagem é essencialmente destituído de dispersantes sem cinzas do tipo carboxílico (por exemplo, dispersantes de succionimida) e de dispersantes de base de Mannich, realizando assim, uma economia de custos sobre os óleos de engrenagem convencionais, que são usados como lubrificantes de transmissão e de eixo. Polimetilacrilatos funcionalizados (PMA) são apresentados como agentes que aperfeiçoam as propriedades do óleo de engrenagem e permitem a omissão de dispersantes convencionais.
