The invention discloses a pure electric high-speed reduction gearbox. The pure electric high-speed reduction gearbox comprises a first-stage planetary transmission system and a first-stage parallel shaft transmission system which are arranged in a shell; the input end of a planetary transmission system is connected with a driving motor, a small gear of the parallel shaft transmission system is fixed to the output end of the planetary transmission system, and a large gear of the parallel shaft transmission system is connected with a differential mechanism; the planetary transmission system comprises an input sun wheel shaft, a planet carrier, a sun wheel, a gear ring and planet wheels, the center of the sun wheel is connected to the input sun wheel shaft, the plurality of planet wheels are arranged on the planet carrier and meshed with the gear ring and the sun wheel correspondingly, and the two ends of the input sun wheel shaft are rotationally connected with one side of the shell and the planet carrier correspondingly; and the output end of the planet carrier is connected with a planet carrier output shaft, and the planet carrier output shaft is rotationally connected with the other side of the shell. The pure electric high-speed reduction gearbox is compact in structure, large in reduction ratio, small in overall size, small in occupied space, light in weight, flexible in arrangement, capable of achieving integration with a motor to different degrees and suitable for being matched with the ultra-high-speed motor.
