Abstract: The transmission principle of belt conveyor is studied from the perspectives of kinematics and mechanics, and a set of optimized electric drum schemes using the planetary gear trains as transmission devices is proposed. The finite element analysis software is used to analyze the strength and stiffness of the electric drum; at the same time, a simulation model of the electric drum transmission system is constructed by using ADAMS software. The significant improvement of dynamic performance of the electric drum by the planetary gear train as a transmission device is verified through engineering practice; and a complete set of calculation, design, and analysis methods is formed. It provides relevant reference and basis for the application and research of the planetary gear train electric drum.
