The invention particularly relates to a drive device special for a high-power brick machine. The problems that an existing drive device used for the brick machine is large in impact force, likely to cause box expansion and gear tooth breakage and limited in installation are solved. A main output shaft and a sun gear shaft are arranged in a main box body. A driving gear is arranged on the main output shaft. A sun gear and a main input bearing are arranged on the sun gear shaft. An inner gear ring is arranged outside the sun gear. An annular connection plate connected with the inner gear ring through bolts is arranged in the main box body. Two auxiliary output shafts are arranged in an auxiliary box body. A driving gear I and a driven gear are arranged on one auxiliary output shaft, and a driven gear I is arranged on the other auxiliary output shaft. An oil pump is arranged on the upper end face of the main box body. An oil inlet of the oil pump is connected with an oil suction pipeline. A lubricating oil pipe is arranged at an oil outlet of the oil pump. By means of the drive device, the bearing capacity of a speed reducer is improved, the requirement for the small on-site installation space is ensured, and meanwhile lubricating and cooling in the drive device are ensured.
