[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Figure 1 A schematic diagram of the gearbox motor in an embodiment of this utility model is shown. The gearbox motor includes a motor body 1 and a gearbox 2. The gearbox 2 is provided with a large gear 5 and a small gear 6 that mesh with each other. The large gear 5 and the small gear 6 form a speed-increasing gear set. The first output shaft 3 of the motor body 1 is correspondingly engaged at the rotation center position of the large gear 5. A mounting seat is provided at the rotation center position of the small gear 6. The gearbox 2 forms an assembly position for the second output shaft 4 based on the mounting seat. According to the actual usage scenario requirements, the model and specifications of the second output shaft 4 can be adjusted so that the motor body 1 can be equipped with different specifications of the second output shaft 4 based on the gearbox 2, thereby meeting the usage scenario requirements of different electrical products.

[0026] Furthermore, the first output shaft 3 of the motor body 1 is used to drive the large gear 5 to rotate, and based on the meshing relationship between the large gear 5 and the small gear 6, the first output shaft 3 can drive the small gear 6 to rotate through the rotation of the large gear 5, thereby adjusting the speed of the small gear 6 and simultaneously increasing the output speed of the second output shaft 4.

[0027] Specifically, the gearbox 2 includes an upper cover and a lower cover, which are fitted together to form a gearbox structure. The speed-increasing gear set is housed within the gearbox structure. By fitting the upper cover and the lower cover together, the speed-increasing gear set is limited to ensure stable operation. The gearbox 2 structure formed by the upper cover and the lower cover protects the speed-increasing gear set, thereby ensuring its operational safety and stability.

[0028] Specifically, the upper cover is provided with a first mounting slot and a second mounting slot, and the lower cover is provided with a third mounting slot and a fourth mounting slot. The first mounting slot and the third mounting slot form a mounting position to accommodate the large gear 5, and the second mounting slot and the fourth mounting slot form a mounting position to accommodate the small gear 6. The first mounting slot and the third mounting slot are used to position the large gear 5 so that the large gear 5 can be confined between the upper cover and the lower cover. The second mounting slot and the fourth mounting slot are used to position the small gear 6 so that the small gear 6 can be accurately assembled into the gearbox 2 structure formed by the upper cover and the lower cover. Through the assembly and cooperation between the large gear 5 and the small gear 6, the setting requirements of the speed-increasing gear set inside the gearbox 2 are met.

[0029] Furthermore, the large gear 5 and the small gear 6 are positioned by setting the first mounting slot, the second mounting slot, the third mounting slot, and the fourth mounting slot to ensure the installation accuracy and stability of the large gear 5 and the small gear 6.

[0030] Specifically, the gearbox 2 is equipped with a plurality of rolling bearings 23, which are respectively disposed in the first mounting slot, the second mounting slot, the third mounting slot, and the fourth mounting slot. The large gear 5 is mounted between the first mounting slot and the third mounting slot based on the rolling bearings 23, so that the large gear 5 can rotate inside the gearbox 2. The first output shaft 3 of the motor body 1 drives and connects to the large gear 5. When the first output shaft 3 is driven to rotate by the motor body 1, the large gear 5 can be driven to rotate. At the same time, the rotation of the large gear 5 drives the small gear 6 to rotate synchronously.

[0031] Furthermore, the fitting structure between the small gear 6 and the second and fourth mounting slots can refer to the mounting structure of the large gear 5, which will not be described in detail here.

[0032] Specifically, the upper cover and the lower cover are fixed together by bolts. The mating positions of the upper cover and the lower cover are provided with several threaded grooves. The upper cover and the lower cover are connected and fixed by bolts, so that the upper cover and the lower cover fit together to form the gearbox 2 structure. This can ensure the structural stability of the fit between the upper cover and the lower cover, and at the same time facilitate the disassembly and assembly of the upper cover and the lower cover for maintenance of the speed-increasing gear set.

[0033] Specifically, the bottom of the lower cover extends downward to form two symmetrically distributed connecting protrusions 211. The connecting protrusions 211 are connected to the top surface of the motor body 1. The lower cover abuts against the top surface of the motor body 1 based on the connecting protrusions 211, so that the lower cover can be structurally connected to the motor body 1 based on the connecting protrusions 211, thereby improving the fit stability between the lower cover and the motor body 1.

[0034] Furthermore, the connecting boss 211 and the lower cover can be configured as an integrally formed structure, thereby improving the structural reliability of the lower cover. Based on the connection between the connecting boss 211 and the motor body 1, a preset distance can be formed between the main structure of the gearbox 2 and the motor body 1, thereby ensuring that the motor body 1 has good heat dissipation space to meet the working heat dissipation requirements of the motor body 1.

[0035] Specifically, the top of the motor body 1 is provided with a mating groove, and the bottom of the connecting boss 211 is provided with a mating post 2111. The connecting boss 211 is inserted into the mating groove of the motor body 1 based on the mating post 2111. By providing the mating post 2111 at the bottom of the connecting boss 211, and by engaging the mating post 2111 with the mating groove of the motor body 1, the motor body 1 and the gearbox 2 are tightly connected, thereby improving the reliability of the structural fit between the gearbox 2 and the motor body 1.

[0036] Furthermore, a lower bracket 11 is provided at the bottom of the motor body 1, and a connecting screw is provided at the connection position of the lower bracket 11. The lower bracket 11 is provided on the stator assembly 12 of the motor body 1, and the lower bracket 11 covers the rotor assembly 13 of the motor body 1 to provide protection for the rotor assembly 13 of the motor body 1.

[0037] The connecting screw passes through the motor body 1 from bottom to top and is threadedly connected to the connecting boss 211. Based on the connecting screw, the stator assembly 12 and the lower bracket 11 of the motor body 1 are connected, and the threaded connection between the connecting boss 211 of the motor body 1 and the lower cover is realized simultaneously, which can improve the stability and reliability of the structural connection between the gearbox 2 and the motor body 1.

[0038] Furthermore, the lower cover supports the motor body 1 based on the connecting boss 211 and provides an installation platform for the lower bracket 11 of the motor body 1. The connection structure of the long screw can improve the stability and reliability of the assembly connection between the gearbox 2 and the motor body 1.

[0039] Furthermore, by supporting the motor body 1 with the gearbox 2, the structural configuration of the upper bracket of the motor body 1 can be reduced, and the heat dissipation effect of the motor body 1 during operation can be improved based on the gap formed between the motor body 1 and the gearbox 2 structure.

[0040] Specifically, a support column 212 is provided between the gearbox 2 and the motor body 1. The support column 212 is connected to the motor body 1 by bolts and abuts against the top surface of the motor body 1. The support column 212 can improve the reliability of the structural connection between the gearbox 2 and the motor body 1. In order to improve the transmission stability between the first output shaft 3 of the motor body 1 and the second output shaft 4 of the gearbox 2, the speed-increasing gear set has good structural connection stability and structural rigidity. By setting the structure of the support column 212, the stability and reliability of the structural fit between the gearbox 2 and the motor body 1 can be improved, and the support capacity of the motor body 1 for the structure of the gearbox 2 can be improved, ensuring the stability of the gearbox 2's operation.

[0041] Furthermore, a number of reinforcing ribs are provided on the outer circumference of the support column 212. The reinforcing ribs improve the structural rigidity of the support rod, so that the support rod has good support performance and meets the structural connection stability and safety requirements between the motor body 1 and the gearbox 2.

[0042] This utility model embodiment provides a gearbox motor. By setting a gearbox 2 on the motor body 1, the position of the output shaft of the motor body 1 can be adjusted based on the gearbox 2, which can meet the motor installation requirements of different positions. Furthermore, the output speed of the motor shaft can be adjusted based on the speed-increasing gear set, thereby improving the output efficiency of the motor shaft, reducing the workload of the motor body 1, and effectively extending the service life of the shaded pole motor.

[0043] Furthermore, the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
