The invention relates to co-rotating twin-screw extrusion equipment and discloses a novel internal gear transmission co-rotating twin-screw reducer. It mainly comprises an upper housing, a lower housing, two dividing gears, gear shafts, an input gear shaft, internal and external gears, a short output gear shaft, a long output shaft, tandem bearings, thrust bearings, bearing seats and disc springs. The input gear shaft transmits half power to the long output shaft through No.Ⅱ dividing gear, and delivers the other half power to the short output shaft through No.Ⅰ dividing gear, spline shaft, intermediate gear shaft and internal-external gear combination. The novel structure realizes power split transmission via external gears and secondary confluence via internal gears. It features innovative transmission principle, compact structure, simple phase adjustment of dual output shafts, convenient torque error compensation, low manufacturing cost and easy maintenance for industrial promotion.
