Abstract
The utility model provides a tunnel gate transmission system. A motor decelerator inside the transmission system is connected with a worm through a motor shaft coupling, a transmission screw, universal shaft couplings, and a connecting shaft. The worm drives a worm gear through gear engagement. By adopting the structure of a high transmission ratio of the worm gear to the worm, the system can drive heavy devices with large sizes through relatively small torque. By adopting the universal shaft couplings, the system can achieve certain angle changes of driving force and facilitate the driving of structures which are not in the same plane or the same line. Furthermore, the tunnel gate transmission system has the advantages of simple structure, reliable transmission and convenient maintenance.
