Abstract

Patente de Invenção: <B>"ESTRUTURA ROTACIONAL DE EIXO DE MANIVELA PARA MOTOR DE QUATRO CICLOS"<D>. Uma estrutura rotacional de eixo de manivela para um motor de quatro ciclos tendo um mancal esférico radial dentro de uma primeira seção de mancal principal de uma caixa de manivela, um mancal de cilindro radial ajustado dentro de uma segunda seção de mancal principal da caixa de manivela, um eixo de manivela sendo sustentado de modo a poder girar por meio do mancal esférico radial e do mancal de cilindro radial, e a tubeira de esguicho de óleo para o resfriamento de um pistão que é provido na segunda seção de mancal principal. Mesmo que o diâmetro dos eixos para fixação seja igual, o diâmetro externo do eixo de cilindro radial pode ser feito menor em comparação ao diâmetro externo do mancal esférico radial. Por conseguinte, mesmo que a tubeira de esguicho de óleo seja provida na segunda seção de mancal principal dentro da qual o mancal de cilindro radial se ajusta, a distância a partir do centro de eixo de manivela para a posição de fixação do esguicho de óleo pode ser feita menor e o próprio motor pode ser reduzido em tamanho.
