[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0013] like Figure 1 As shown, the heat dissipation gearbox comprises a gearbox body 1, a planetary gear set 2 installed in the gearbox body 1, and a transmission shaft 3 for driving the planetary gear set 2. The transmission shaft 3 runs through the gearbox body 1 and is used to drive the planetary gear set 2 to move. The gearbox body 1 is provided with two heat dissipation mechanisms for rapid heat dissipation and volatilization. The two heat dissipation mechanisms are respectively installed at the output end and the input end of the gearbox body 1 and are matched with the transmission shaft 3 in transmission. The heat dissipation mechanism comprises a connector 4 installed on the gearbox body 1 and a heat dissipation fan 5 for rapid air cooling and heat dissipation. The connector 4 has a cavity inside for installing the heat dissipation fan 5. The connecting member 4 is arranged in a cylindrical structure, and cooling fans 5 connected to the inside of the cavity are provided at both ends of the connecting member 4. The transmission shaft 3 runs through the connecting member 4, and can drive the cooling fan 5 inside the cavity to rotate synchronously with the planetary gear set 2, and a plurality of through holes 7 for improving the heat dissipation efficiency are also provided on the connecting member 4. The above-mentioned structural design is simple, and heat dissipation mechanisms are respectively installed at the input end and the output end of the gearbox body 1. Through the structural design of the heat dissipation mechanism, the air inside the gearbox body 1 can be quickly converted, thereby realizing heat replacement, performing rapid heat dissipation, and improving the performance and life of internal components.

[0014] To elaborate further, in order to achieve rapid cooling and heat dissipation of the connector 4 itself, a plurality of through holes 7 are arranged in a circumferential direction along the central axis of the connector 4 and are located in the side wall of the cavity, which can be used for rapid cooling and heat dissipation of the connector 4 itself.

[0015] To further explain, in order to achieve rapid air cooling and heat dissipation inside the gearbox body 1, the cooling fan 5 is arranged in a trapezoidal structure and is arranged in sequence and at intervals in a circumferential direction along the central axis of the connecting member 4. The cooling fans 5 at both ends of the connecting member 4 and the cooling fan 5 in the cavity can quickly achieve air cooling and heat dissipation of the internal heat of the gearbox body 1. The connecting member 4 is a detachable split structure and is respectively installed on the input and output ends of the gearbox body 1, and synchronously drives the cooling fan 5 and the planetary gear set 2 in the cavity to rotate synchronously through the transmission shaft 3. The planetary gear set 2 and the cooling fan 5 are both driven to rotate synchronously through transmission.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0017] Although the terms such as gearbox body 1, planetary gear set 2, transmission shaft 3, connecting member 4, cooling fan 5, cooling fan 5, through hole 7 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
