Abstract

"ESTRUTURA DE MANCAL PARA EIXO DE MANIVELA EM MOTOR DE COMBUSTãO INTERNA". A presente invenção visa assegurar que o movimento na direção axial de um sulco externo de um mancal de rolamento que se origina, necessariamente, da montagem de um meio de absorção de folga pode ser restringido, em uma estrutura em que um eixo de manivela de um motor de combustão interna é suportado giravelmente em um eixo de manivela através de mancais de rolamento e a folga na direção radial gerada entre o sulco externo do mancal de rolamento e um orifício de mancal no cárter é absorvido pelo meio de absorção de folga. Desta forma é provida uma estrutura em que um eixo de manivela (6) é suportado giravelmente em um cárter (10) através de mancais de rolamento BB e um meio de absorção de folga (A) é proporcionado para absorver a folga na direção radial gerada entre o sulco externo (23) do mancal de rolamento BB e um orifício de mancal (18) no cárter (10), um meio de restrição de movimento (S) para restringir o sulco externo (23) de se mover na direção radial é proporcionado entre o sulco externo (23) do mancal de rolamento BB e o cárter (10).
