ABSTRACT:
To provide a roller chain according to the present device pertaining to a bushed chain with an oil-impregnated sintered bushing fitted on a roller, which has an improved roller retaining power required during the sliding of the roller chain, and further requires no installation time and labor at the time of unlinking and linking of the roller chain, thereby preventing impairing or breaking each member. Pin diameter is increased to lower a bearing surface pressure to thereby improve wear resistance. Furthermore, the thickness of the sintered bushing axially supported on a pin is made nearly equal to that of the roller. According to the present device, the chain provided is a bushed chain with an oil-impregnated sintered bushing fitted on a roller, in which the working accuracy of the punched surface of a link plate has been improved, requiring no staking of a pin end face after installation.
