The utility model discloses a theory of operation is: the first power source 20 transmits its power to the first input wheel 1 when rotating, the first input wheel 1 transmits the power to the first intermediate wheel 2 through the corresponding external gear pair and performs primary amplification of torque, the first intermediate wheel 2 transmits the power to the first output wheel 3 through the corresponding external gear pair and performs secondary amplification of torque, and at this time, the first output wheel 3 is in a low-speed and high-torque state; the first output wheel 3 transmits power to the inner shaft 9 through an internal gear pair A at the core part of the first output wheel 3 so as to drive the third input wheel 11 to rotate, and the first output wheel 3 and the third input wheel 11 are in a constant-speed equal-torque state; the third input wheel 11 and the third output wheel 14 form a speed-increasing external gear pair to transmit power to the first winding drum 12 and realize speed increase of the first winding drum 12 so as to meet the requirement of the high-speed production of the unit on the rotating speed of the first winding drum 12.
The energy transmission flow of the second power source 21 for finally transmitting power to the second winding drum 13 is similar to the energy transmission flow of the first power source 20 for finally transmitting power to the first winding drum 12, that is, the second power source 21 sequentially transmits power to the second input wheel 6, the second intermediate wheel 5, the second output wheel 4, the outer shaft 7, the fourth input wheel 10, the fourth output wheel 15 and the second winding drum 13, and finally the requirements of the set on the rotating speed and the torque of the second winding drum 13 in high-speed production are met.
Because the internal shaft 9 and the external shaft 7 are socket-jointed and distributed and have a 15-20mm gap, the first power source 20 and the second power source 21 can respectively drive the first winding drum 12 and the second winding drum 13 and realize the independent control of the rotating speed, the steering and the torque of the first winding drum and the second winding drum, which is the key point of realizing the parallel transmission of the utility model.
The first and second winding drums 12 and 13 are rotated with the rotor housing 18 relative to the inner and outer shafts 9 and 7 by the outer races of the third and fourth input wheels 11 and 10 rotating about the common axis of the inner and outer shafts 9 and 7.
The significance of the two times of torque amplification of the stator box 19 is to ensure that the large torque output by the first power source 20 and the second power source 21 is transmitted to the rotor box 18 through the inner shaft 9 and the outer shaft 7 at relatively low rotating speed, so that when the rotor box 18 and the winding drum thereof rotate relative to the stator box 19, the low-speed smoothness of power transmission can be realized. The speed-increasing outer gear pair formed by the engagement of the third input wheel 11 and the third output wheel 14 and the speed-increasing outer gear pair formed by the engagement of the fourth input wheel 10 and the fourth output wheel 15 increase speed, which means that the speed of the low-speed stable power transmitted by the stator box 19 is increased to meet the requirement of the high-speed production of the unit on the rotating speed of the winding drum. And because the winding drum and the input shaft system of the rotor box body are both arranged and supported in the rotor box body 18, the speed increasing of the speed increasing gear pair can not cause the instability of the transmission device.
