Problems solved by technology

[0008] In the prior art, the output of the ring gear 22 is 0 when the power generation is stopped, and the rotation speed of the ring gear 22 is 0, and the planetary row 2 cannot obtain splash lubrication, so it is necessary to add a set of machines The oil pump lubricates the gear train, the structure is complicated and the mechanical loss of the system is increased
In the prior art, the speed ratio of the planetary row 2 is k=2.6, and the size of k is restricted by the system and cannot be made larger or smaller
If k is made larger, the output torque ratio of the planetary row can be increased, and the volume and weight of the generator can be reduced; however, if k increases, the efficiency of the planetary row will be reduced, and the diameter and inertia of the ring gear will be increased at the same time, which will make the vibration of the mechanism and the mechanical Increased loss
