Abstract

a presente descrição se refere a um conjunto mecânico de dois componentes mecânicos que giram um com relação ao outro sendo possível obter um mancal de fluido autocentrante; compreende um primeiro componente provido com uma cavidade cilíndrica, um segundo componente (34) que compreende pelo menos uma porção cilíndrica engatada na cavidade cilíndrica do primeiro componente, um espaço que separa a porção cilíndrica e a parede da cavidade cilíndrica de modo a permitir movimento relativo de rotação entre o primeiro e segundo componente (34), e uma rede de distribuição de lubrificante (37, 38) configurada para alimentar dito interstício com um lubrificante de fluido de modo a formar um mancal de fluido; uma primeira superfície (34s) fora da superfície mais baixa da cavidade cilíndrica do primeiro componente e da superfície externa da porção cilíndrica do segundo componente é equipada com pelo menos dois orifícios de entrada de lubrificante (39a, 39b) distantes um do outro por mais do que 120° em torno do eixo geométrico principal (f) da primeira superfície (34s), e a primeira superfície (34s) também tem pelo menos uma ranhura circunferencial (40a) que se estende de forma circunferencial, na direção de rotação relativa da segunda de ditas superfícies com relação à primeira superfície (34s), a partir da vizinhança de um primeiro orifício de entrada de lubrificante (39a) sobre pelo menos 100°.
