The chain conveyor system is a product for the environment and productivity, allowing users to work efficiently. The existing chain conveyor system is operated by a single drive motor, so all processes are driven at the same time, so if the working hours are different, they are not time-efficient. Due to the nature of the chain conveyor system, a lubricant is used to prevent noise and dust caused by chain driving, and even if only one section of the chain conveyor breaks down, the entire line must be stopped in order to repair it. This study was conducted with a focus on localizing the flexible drive system, securing the reliability of the drive wheel that operates smoothly even in fatigue situations, prototyping and performance evaluation of the flexible drive system.
