Abstract：In order to solve the problem of insufficient of driving power，poor stiffness and large-dimension structure of heavy load and long span frame device，such as orbital towing equipment，gantry device，raised and lowered automatically equipment，a double gear of gradual synchronous driving system based on electrical servo drive technology was introduced. A driving gear was adopted first to drive the load of a gear in the gradual synchronous driving system and then the other driving gear was adopted. Delta's CNC system was adopted to realize the double gear synchronous control system with high precision. The results indicate that，the system is featured by highly reliability，convenient control，start and stop with high synchronous precision.
