Abstract

"ESTRUTURA DE PREVENçãO DE QUEDA DE CORRENTE DE CAME PARA UM MOTOR DE COMBUSTãO INTERNA". A presente invenção refere-se a uma estrutura de prevenção de queda de corrente de came para um motor de combustão interna tendo um eixo de manivela (8) suportado de forma rotativa por uma caixa de manivela via um mancal de esfera (11), e uma chapa de prevenção de queda de corrente de came (28) provida nas proximidades da periferia externa de uma roda dentada de acionamento (18) para uma corrente de came (20) em um sistema de transmissão de engrenagem de válvula encaixada no eixo de manivela (8), de modo a prover um membro que pode servir como uma chapa de prevenção de queda de corrente de came (28) e um membro de fixação de porção de base de um tensionador de came, de modo que o número de componentes e o trabalho de montagem sejam reduzidos, e, deste modo, a produtividade é aumentada."CAMCORD DROP PREVENTION STRUCTURE FOR AN INTERNAL COMBUSTION ENGINE". The present invention relates to a cam current prevention structure for an internal combustion engine having a crank shaft (8) rotatably supported by a crank box via a ball bearing (11), and a cam chain fall prevention plate (28) provided near the outer periphery of a drive sprocket (18) for a cam chain (20) in a valve gear transmission system fitted to the crankshaft (8) to provide a member that can serve as a cam chain fall arrest plate (28) and a base portion securing member of a cam tensioner, such that the number of components and assembly work is reduced, and thus productivity is increased.
