Single-input double-output transmission device

The invention provides a single-input double-output transmission device. The single-input double-output transmission device comprises a base, and further comprises planet wheels, an input shaft, a fixed gear, a rotary supporting frame and transmission shafts rotationally connected with the rotary supporting frame. The input shaft is provided with a central gear. The transmission shaft is provided with eccentric bearings and a transmission gear engaged with the central gear. The planet wheels are provided with inner gear rings and bearing holes, the tooth number of the inner gear rings is 1-4 larger than that of the fixed gear, and the fixed gear is fixedly connected with the base. The eccentric bearings are installed in the bearing holes. The rotary supporting frame is provided with an outer gear ring and a first end surface tooth, the outer gear ring is coaxial with the input shaft, and the plane where the first end surface tooth is located is perpendicular to the input shaft. The two ends of each transmissi
