Abstract

"ESTRUTURA DE MANCAL DE EIXO DE MANIVELA EM UM MOTOR DE COMBUSTãO INTERNA". A presente invenção refere-se a uma estrutura de mancal de um eixo de manivela (6) em um motor de combustão interna que suporta um eixo de manivela (6) em uma caixa de manivela (10) com mancais de rolamento, que inclui um dispositivo de absorção de jogo de modo a absorver o jogo na direção radial gerada entre um anel externo (27) do mancal de rolamento e um furo de mancal (18) da caixa de manivela (10). O dispositivo de absorção de jogo inclui um tampão de impulso (30) que empurra um anel externo (23) do mancal de esfera (BB) na direção perpendicular a um eixo geométrico do eixo de manivela. O tampão de impulso (30) fica disposto paralelo ao eixo de manivela (6) entre o cilindro e o eixo de manivela (10). O anel externo (23) do mancal de esfera (BB) é polarizado de forma resiliente na direção de um lado do furo de mancal (18) da caixa de manivela (10) que recebe uma pressão de explosão. Como um resultado, a geração de um som de impacto que é atribuído ao 'jogo' acima mencionado pode ser muito reduzida mesmo com relação a um motor de combustão interna com uma pressão de explosão elevada.
