Proposal of Operation Methods of the Square-Duct Cleaning Machine with Multistage Planetary Gear Mechanism

This paper describes operation methods of a cleaning machine using a multistage planetary gear mechanism to select a propulsion speed of the machine based on the cleaning rate required by the user when the machine is used in a real environment, to develop a design theory for a cleaning machine that cleans duct walls while running in ducts. In a previous study, a cleaning machine capable of scrubbing the entire inner wall of a square duct was developed. However, the propulsion speed at which the machine runs in ducts to clean duct walls while propelling on its own was not clarified. This paper describes a grease cleaning experiment to verify the propulsion speed. In addition, we propose the operating methods of the machine according as the required cleaning rate. The user of the machine can select the propulsion speed based on the required cleaning rate.
