A closed-shell-belt type of transmission technology is presented to stabilize and make the transmission of shells accurate to the automation and meanwhile realize the continuous shell-feeding. Detailed discussion concentrates on such two aspects as the technical condition and the merits, and tests are carried out on the target machine. The testing results show that the system is simple structure and flexible layout, which can be comprehensively used in chainless shell-feeding system mounted on warships, vehicles and planes-mounted artillery, having promising application prospect.
