実機における摩耗の再現性に優れたチェーン用円筒面摺動式摩耗試験機の開発

Roller chains are commonly used for transmission of mechanical power on many kinds industrial machinery. Roller chain makers have done a lot of efforts to improve the wear resistance by using conventional types of wear testing machine. However, such conventional wear testing needs huge amount of time and cost. Therefore, this study focuses on developing a new wear testing machine, which can evaluate the wear amount efficiently without using main chain components such as inner plate, outer plate and roller. The experimental results show that this newly developed wear testing machine may realize the almost same wear rate under stable condition and similar wear status of the conventional chain type testing machine. The newly developed wear testing machine may be useful for improving the wear resistance of roller chains conveniently compared to the conventional chain type testing machine.
