Abstract

"MOTOR DE COMBUSTãO INTERNA DO TIPO OHC". A presente invenção refere-se a um motor de combustão interna do tipo OHC que inclui um eixo de cames (22) que gira junto com um eixo de manivela (8) provido em uma cabeça de cilindro, (6) o qual tem objetivo de melhorar a construção da técnica anterior que exige muitas etapas de fabricação complicadas como a formação de uma parte de retenção de mancal de eixo de cames que inclui duas metades usando a superfície de junção entre peças fabricadas separadamente, tal como uma cabeça de cilindro (6) ou uma tampa de cabeça de cilindro (7), e facilitar a fabricação da parte de retenção de mancal e a operação de montagem de eixo de cames (22). Um prendedor de eixo de cames (21) para suportar rotativamente o eixo de cames (22) é fabricado separadamente da supracitada cabeça de cilindro (6) ou da tampa de cabeça de cilindro (7), e é fixado junto com um pino roscado (50) que passa através de um cilindro."OHC TYPE INTERNAL FUEL ENGINE". The present invention relates to an OHC type internal combustion engine which includes a camshaft (22) which rotates together with a crankshaft (8) provided on a cylinder head (6) which is intended to improving the prior art construction requiring many complicated manufacturing steps such as forming a camshaft bearing retaining portion that includes two halves using the separately fabricated joining surface such as a cylinder head (6) or a cylinder head cover (7), and facilitate bearing retaining portion fabrication and camshaft mounting operation (22). A camshaft fastener (21) for rotatably supporting the camshaft (22) is manufactured separately from the aforementioned cylinder head (6) or cylinder head cover (7), and is fixed together with a threaded pin ( 50) passing through a cylinder.
