Main transmission system of numerical control boring machine

The main transmission system of the numerical control boring machine relates to the field of numerical control boring machines and comprises a bottom plate, a mounting frame is arranged at one end of the top of the bottom plate, a driving rotating shaft is rotatably connected to one side of the mounting frame, a gear ring is arranged on the driving rotating shaft, and motors are arranged on the top face of the bottom plate and located on the two sides of the driving rotating shaft. The output ends of the two motors are both connected with anti-backlash gears engaged with the gear ring, and a precise speed reducer is installed at the end, away from the installation frame, of the top face of the bottom plate. The motors are installed on the two sides of the driving rotating shaft on the top of the bottom plate, the output ends of the motors are connected with the anti-backlash gears matched with the gear rings, the inner wall of the open pipe of the protective shell is rotationally connected with the multiple s
