1. A planetary transmission system with a planetary gear double-row parallel uniform distribution shunting structure comprises a base, a left shell, a right shell and a planetary gear transmission mechanism;

  • the left shell and the right shell are respectively arranged at two ends of the base, the end surfaces of the left shell and the right shell are respectively provided with a left end cover and a right end cover, and the planetary gear transmission mechanism is arranged among the left shell, the base and the right shell;

    the planetary gear transmission mechanism is characterized by comprising an input shaft, a sun gear, a planetary gear mechanism, a planet carrier device, a fixed inner gear and an output shaft;

    the input shaft penetrates through the left shell, the sun gear is fixedly arranged on the input shaft, the planetary gear mechanism comprises a left planetary gear train and a right planetary gear train which are distributed in the direction of the axis of the sun gear, and the left planetary gear train and the right planetary gear train are in meshing transmission with the sun gear and are arranged at intervals;

    the planet carrier device is vertically arranged in the base and comprises a planet carrier and a planet carrier adapter plate which are fixedly connected into a whole, and the left planetary gear train and the right planetary gear train are both fixed on the planet carrier device;

    the fixed internal gear is fixed in the base, and the left planetary gear train and the right planetary gear train are in meshing transmission with the fixed internal gear;

    the output shaft penetrates through the right shell, and the output shaft is fixedly connected with the planet carrier adapter plate;

    the left planetary gear train comprises n left planetary gears which are uniformly distributed around the central line of the sun gear, and the n left planetary gears are in meshing transmission with the sun gear;

    the right planetary gear train comprises n right planetary gears which are uniformly distributed around the central line of the sun gear, and the n right planetary gears are in meshing transmission with the sun gear;

    an included angle between any planet wheel in the n left planet wheels and the adjacent right planet wheel is 360 degrees/2 n, and the n left planet wheels and the n right planet wheels are uniformly distributed in the circumferential direction of the sun wheel;

    two ends of the left planet wheel are fixed on the planet carrier;

    one end of the right planet wheel is fixed on the planet carrier, and the other end of the right planet wheel is fixed on the planet carrier adapter plate; and

    bearings are arranged at the supporting positions of the left planet wheel and the right planet wheel on the planet carrier device.
