Abstract

"BOMBA DE ENGRENAGEM". A presente invenção refere-se a uma bomba de engrenagem que incorpora um anel de engrenagem (16) suportado para rotação, uma roda de engrenagem (17) disposta excentricamente dentro do anel de engrenagem (16), e um eixo rotativo (9) incorporando uma parte que se estende através de um furo (18) na roda de engrenagem. A dita parte de eixo (9) incorpora uma primeira superfície (211) e a roda de engrenagem incorpora uma segunda superfície (221), cujas superfícies são assim formatadas de modo a permitir a transferência de movimento rotativo do eixo (9) para a roda de engrenagem (17). A dita transferência entre a primeira superfície (211) e a segunda superfície (221) ocorre por meio de uma região de contato (a) . A região de contato (a) tem uma extensão axial igual ao menos que metade da extensão axial da roda de engrenagem (b) e que é dividida por um plano radial (c) que se estende centralmente através da roda de engrenagem (17).
