A power input shaft (1) is of a double-torque driving type, the front end of the power input shaft drives double inner gears, the rear end of the power input shaft drives a planetary gear mechanism, the front end of a duplex outer gear ring (9) is provided with double inner meshing tooth paths, and the rear end of the duplex outer gear ring (9) is provided with a meshing tooth path of a planetary gear (6). Steel ball holes (21) are formed in the center lines of the duplex outer gear rings (9) in an equally-divided mode, steel balls (6) with the same number are arranged in the holes, stepless variable torque is generated in the mode that elastic steel rings (7) and (8) exert pressing force on the steel balls (6) in the steel ball holes (21), due to the fact that part of ball bodies of the arranged steel balls (6) occupy tooth paths, rotating tooth heads must eject the steel balls (6) upwards, and the steel balls (6) are driven to rotate. Meanwhile, elastic steel rings (7) and (8) with pressure are ejected. The
