High-precision mechanical synchronous walking heavy-load transmission mechanism

The utility model provides a high-precision mechanical synchronous walking heavy-load transmission mechanism which comprises a base, a power source is arranged on one side of the base, a synchronous shaft is connected to the power source in a driving mode, right-angle reversers used for converting the movement direction are arranged at the two ends of the synchronous shaft, and the right-angle reversers are fixedly arranged on the base. Wherein the bottom of the right-angle reverser penetrates through the base and is provided with a driving gear; steel rails are slidably arranged on the bottom faces of the two ends of the base, and racks are arranged on the inner sides of the steel rails and engaged with the driving gears. A power source is utilized, driving gears at the two ends of a base are in driving connection with the power source through the same synchronizing shaft and are matched with racks arranged on the inner side of the base to drive a heavy load device to operate, 90-degree change of the shaft t
