The scheme has the following advantages: according to the invention, the main shaft 1 and the generator 2 are arranged, and the driving gear 4 of the main shaft 1 is meshed with the driven gear 5 on the shaft body of the generator 2, so that a gear box is omitted, and the space of equipment is saved.
In this embodiment, the main shaft 1 drives the driven gear 5 on the generator 2 to rotate by driving the driving gear 4, so as to generate electricity for the generator 2.
Specifically, the main shaft 1 is connected with a wind wheel of the wind driven generator 2 through a hub 3, the wind wheel rotates under the action of external wind force and drives the main shaft 1 to rotate, a driving gear 4 is sleeved on the main shaft 1, the driving gear 4 is meshed with a driven gear 5 on the generator 2, so that the driving gear 4 drives the meshed driven gear 5 to rotate when rotating, and the driven gear 5 rotates to generate electricity for the generator 2.
In this embodiment, the generators 2 are two 50KW generators 2, the two generators 2 are disposed on the left and right sides of the driving gear 4, and the two generators 2 are symmetrically disposed diagonally, so that the driving gear 4 and the two driven gears 5 are maintained on the same horizontal line, and a balance state of engagement between the driving gear 4 and the two driven gears 5 is maintained during power generation, thereby preventing the main shaft 1 from yawing due to the change of the rotation speed of the wind wheel. Moreover, when two generators 2 are provided, the driven gear 5 on each generator 2 is engaged with the driving gear 4 at the same time, and at this time, the rotation of the driving gear 4 inevitably drives the driven gears 5 of the two generators 2 to rotate together at the same rotation speed, so that the overall power generation efficiency is improved and the respective power generation efficiency of the two generators 2 is ensured to be the same.
In the present embodiment, the outer diameter of the driving gear 4 is larger than that of the driven gear 5.
Specifically, the larger the outer diameter of the driving gear 4 is, the larger the outer diameter of the driven gear 5 is, and the more labor is saved when the driving gear 4 makes one rotation in the same mesh, and the faster the rotation speeds of the two driven gears 5 are, the higher the power generation efficiency is.
In this embodiment, the generator 2 is disposed on the main machine base 9, and the main machine base 9 is further provided with a cooling oil pool 6 for cooling the driven gear 5.
In order to avoid that the generator 2 is damaged by high temperature generated by the over-high rotating speed of the driven gear 5, the generator 2 is arranged on the main machine base 9, the cooling oil pool 6 for cooling the driven gear 5 is arranged on the main machine base 9, the driven gear 5 is soaked in the cooling oil pool 6, and the temperature of the driven gear 5 can be timely reduced or controlled in a constant temperature environment.

The front bearing 7 and the rear bearing 8 are used for fixing the position of the main shaft 1 and preventing the driving gear 4 from shifting after rotating at an excessively high speed, so that the whole planetary gear generator is prevented from generating faults.
The working principle and the method of the planetary gear generator of the invention are as follows:
when external wind power pushes the wind wheel to rotate, the main shaft 1 connected with the wind wheel through the hub 3 starts to rotate between the front bearing 7 and the rear bearing 8, the main shaft 1 rotates to drive the driving gear 4 arranged on the main shaft 1 to rotate, meanwhile, the driven gears 5 of the generator 2 which are arranged on the left side and the right side of the driving gear 4 and are symmetrically arranged in an oblique and diagonal mode start to rotate simultaneously because the driven gears 5 and the driving gear 4 are kept in a meshed relation on the same horizontal line, and when the driven gears 5 rotate, the generator 2 starts to generate electricity. When the temperature of the driven gear 5 rises, because the driven gear 5 is immersed in the cooling oil pool 6, the cooling oil in the cooling oil pool 6 cools the driven gear 5 and controls the driven gear 5 in a relatively stable temperature environment.
The technical scheme described in the embodiment has the following beneficial effects:

(3) The two generators 2 are arranged in an oblique and diagonal symmetrical mode, the main gear of the main shaft 1 and the driven gear of the generators 2 are kept on the same horizontal line, so that the main gear and the driven gear can resist torque mutually, and the main shaft 1 is prevented from yawing due to the change of the rotating speed.
(4) Locate generator 2 on main engine base 9, still set up the cooling oil bath 6 that is used for cooling driven gear 5 on main engine base 9, make the driven gear 5 cooling of generator 2, avoid overheated leading to generator 2 to produce the damage.
