Example Embodiment

[0020] Example
[0021] see Figure 1 to Figure 3 , the present invention provides a technical solution: an ultra-compact gearbox and generator integrated structure, including a gearbox body 2 and a generator body 3, one end of the gearbox body 2 is placed inside one end of the generator body 3, the gear box One end of the box body 2 is fixed with a rear end cover 23 of the gearbox. Through the designed rear end cover 23 of the gearbox and the generator body 3, the rear end cover 23 of the gearbox must bear the load of the secondary planetary carrier 22 and the generator. At the same time, the bearing structure of the generator body 3 adopts a single bearing structure, so that the generator rotor 32 completely acts on the rear end cover 23 of the gearbox, ensuring that the generator rotor 32 is coaxial with the gearbox output shaft 24, The gearbox and some parts of the generator are omitted, which reduces the weight, cost and load. One end of the rear end cover 23 of the gearbox is fixed with a secondary planetary carrier 22, and one end of the inner end of the gearbox body 2 is provided with a low-speed shaft to generate electricity. The interior of the machine body 3 is provided with a stator assembly 31. Through the designed stator assembly 31 of the generator, the stator assembly 31 is connected to the middle body of the gearbox body 2 through fasteners, so that the center of gravity of the generator is further forward, and the structure is more The generator rotor 32 is arranged inside the stator assembly 31, one end of the generator rotor 32 is fitted with the rear end cover 23 of the gearbox, the inside of the generator rotor 32 is arranged with a bearing outer ring 33, and the inner side of the bearing outer ring 33 is arranged There is a bearing inner ring 34, the ends of the bearing inner ring 34 and the bearing outer ring 33 are provided with a drive cover plate 36, the inner center of the gearbox body 2 is provided with a gearbox output shaft 24, and one end of the gearbox output shaft 24 is located Inside the bearing inner ring 34 , the gearbox output shaft 24 and the drive cover 36 are fixed by screws, the end of the generator body 3 is connected with a tube bearing 38 , and the inside of the gearbox output shaft 24 is penetrated by a threading pipe 1 , and the threading pipe One end of 1 is installed on the low-speed shaft, the other end of the threading pipe 1 is installed on the tube bearing 38, a plurality of bosses are fixed on the inner side of the rear end cover 23 of the gearbox, and a brake 37 is installed on the bosses. The output shaft 24 and the brake 37, the gearbox output shaft 24 can not only transmit torque, but also realize the braking effect through the brake 37. The outer side is also designed with a toothed structure, which is convenient for later electric cranking.
