[0002] Traditionally, the third bearing seat of the motor gear is a separate structure, secured by two carbon fiber side panels on the fuselage with screws. Vibration during flight can affect the bearing seat's stability, causing deviations in the motor's output torque, further increasing wear on the motor bearings and reducing their lifespan. Furthermore, because the large gear is made of plastic, it can experience tooth scraping when heated, potentially causing the aircraft to crash. Therefore, this motor-gear integrated bearing seat design maintains concentricity between the motor bearing seats, extending the bearing's lifespan. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0021] See also Figures 1 to 6 The utility model provides a technical solution: a motor-gear integrated bearing seat structure, including a motor 1, a motor gear 4 is tightly fitted on the output shaft of the motor 1, and a large gear plate 7 is engaged on one side of the motor gear 4. The large gear plate 7 is used to connect with other transmission parts. The upper seat 2 and the lower seat 3 are connected on the lower surface of the motor 1 by fasteners. The motor gear 4 is inserted into the lower seat 3 and rotates in the lower seat 3. A bearing mounting groove 22 is provided on the lower surface of the upper seat 2. The diameter of the bearing mounting groove 22 is the same as the inner diameter of the lower seat 3. An upper groove 21 is provided on the upper surface of the upper seat 2. A protrusion 24 is formed between the upper groove 21 and the bearing mounting groove 22. An upper bearing 5 is also connected between the upper seat 2 and the lower seat 3. The upper end of the upper bearing 5 is embedded in the bearing mounting groove 22, and the protrusion 24 limits the upper end surface of the upper bearing 5. The lower end of the upper bearing 5 is sleeved on the upper end of the motor tooth 4, and the lower end of the upper bearing 5 is also located in the lower seat 3. The lower seat 3 is an integrally formed aluminum alloy, which enhances the strength and rigidity of the lower seat 3, further reduces the offset, and improves the concentricity. The tooth portion of the motor tooth 4 limits the lower end face of the upper bearing. The upper bearing 5 is located in the upper seat 2 and the lower seat 3 at the same time, so that the upper seat 2 and the lower seat 3 are on the same center line, which improves the concentricity of the two. Preferably, the upper bearing 5 uses a double-row angular contact bearing, and the inner diameter is changed from the previous 8MM to the current 10MM, which improves the load capacity, and the angular contact bearing withstands the upward pressure of the helical teeth, and the transmission efficiency is higher and smoother, further ensuring the concentricity, reducing the wear of the bearing, reducing the high temperature generated by the wear of the large toothed disc 7, and reducing the risk of high-temperature tooth sweeping.

[0022] like Figure 6 As shown, a connecting hole 23 is provided on the upper seat 2, a corresponding circular hole is also provided on the lower seat 3, and a threaded hole 11 is also provided on the motor 1. The bolt is inserted from the bottom of the lower seat 3 through the circular hole of the lower seat 3 and the connecting hole 23 in sequence, and is inserted into the threaded hole 11 of the motor 1. The bolt enhances the connection strength between the upper seat 2, the lower seat 3 and the motor 1, and at the same time makes the upper seat 2, the lower seat 3 and the motor 1 on the same center of a circle, ensuring concentricity.

[0023] like Figure 2As shown, the upper end of the motor tooth 4 is formed with an upper connector 41, which is cylindrical and is used to install the upper bearing 5. The lower end of the motor tooth 4 is formed with a lower connector 42, which is a connector with spiral teeth formed on the surface. The lower connector 42 is used to install the lower bearing 6, so that the motor tooth 4 can rotate more smoothly in the lower seat 3.

[0024] The lower connector 42 is sleeved with a lower bearing 6 , which is fixed to the inner wall of the lower seat 3 , so that the lower end of the motor gear 4 can rotate smoothly.

[0025] like Figure 1 and 3 As shown, an engagement opening 31 is provided on the side of the lower seat 3, and the large gear plate 7 is arranged on the outside of the engagement opening 31. The side of the large gear plate 7 is embedded in the engagement opening 31, and the large gear plate 7 is limited up and down, meshing with the motor teeth 4. The motor 1 drives the motor teeth 4 to rotate, and further drives the large gear plate 7 to rotate, providing power for the transmission parts of the drone.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
