Specifically, the energy transmitted from the gear box is input from the single motor through the input shaft 11, and then power split is performed to transmit the energy to the first transmission shaft 17 and the second transmission shaft 20, respectively. Wherein the second drive shaft 20 in turn transfers energy directly to the third drive shaft 23. And the first transmission shaft 17 transmits energy to the first output shaft 13 to realize energy output. The third transmission shaft 23 transmits energy to the second output shaft 15 to realize energy output.

The advantage of this is that does not need very big gear, has reduced the volume and the quality of gear, the installation of convenient gear box. The power split transmission type internal mixer gearbox 10 adjusts the center distance between the first output shaft 13 and the second output shaft 15 by controlling the center distance between the third transmission shaft 23 and the second output shaft 15 so as to ensure the center distance required by customers.
The power-split transmission internal mixer gearbox 10 can also achieve the purpose of changing the rotating direction of the second output shaft 15 through the meshing-in and meshing-out directions of the third transmission shaft 23 and the second output shaft 15, so that the rotating directions of the third transmission shaft 23 and the second output shaft 15 are opposite, and the requirement of the rotating direction of the output shafts is met. Meanwhile, the speed ratio required by the third transmission shaft 23 and the second output shaft 15 can be adjusted through the speed ratio of the gear pair at the stage so as to meet the requirement of customers.
Furthermore, the input shaft 11 and the second output shaft 15 can be arranged in the same vertical plane, so that the box body of the power split transmission internal mixer gearbox 10 can be simultaneously used for left transmission and right transmission gear boxes, and the universality of products is greatly improved.
