Specific embodiments

[0016] The following will describe the exemplary embodiments of the present disclosure in more detail with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0017] See Figures 1-3 , a gearbox structure with a radiator structure provided by an embodiment of the present utility model includes a gearbox housing. An input shaft 4 is installed inside the gearbox housing, and the output end of the input shaft 4 passes through the double oil seal 14 and the mounting seat 13 and is connected to the spline sleeve 10. The other end of the spline sleeve 10 is connected to the gear pump 8. The double oil seal 14 is arranged inside the mounting seat 13. The mounting seat 13 is fixedly connected to the gearbox housing through the second bolt 15. The gear pump 8 is fixedly installed on the mounting seat 13 through the first bolt 11.

[0018] An installation plate 1 and a steel pipe 12 are also installed on the gearbox housing. The steel pipe 12 is arranged inside the gearbox housing, with one end extending into the gearbox housing and the other end communicating with the installation plate 1. The installation plate 1 is connected to the filter 3 through a first rubber hose 2. The other end of the filter 3 is connected to the gear pump 8 through a second rubber hose 5. The other end of the gear pump 8 is connected to the radiator 7 through a fourth rubber hose 9. The other end of the radiator 7 is connected to the gearbox housing through a third rubber hose 6.

[0019] A connector is fixedly installed on the gearbox housing, and the connector communicates with the third rubber hose 6 to facilitate the return of the gear oil to the gearbox housing.

[0020] A gear assembly is arranged inside the gearbox housing, and the gear assembly is connected to the input shaft 4 through gear teeth. The operation of the input shaft 4 can drive the gear assembly to shift gears and also drive the gear pump 8 to operate.

[0021] During the use of the present utility model, when the gearbox is working and the input shaft 4 rotates, the gear pump 8 is connected through the spline sleeve 10, so that the gear pump 8 rotates. When the gear pump 8 rotates, it generates pressure, and the gear oil reaches the filter 3 through the steel pipe 12, the installation plate, and the first rubber hose 2, and then reaches the gear pump 8 through the second rubber hose 5. When the gear pump 8 rotates, it generates pressure, and the gear oil enters the radiator 7 through the third rubber hose 6. After being cooled by the radiator 7, the gear oil with reduced temperature returns to the gearbox through the fourth rubber hose 9, thereby achieving the effect of reducing the temperature of the gear oil in the gearbox.

[0022] When the input shaft 4 rotates, the mounting seat 13 is fixed to the reducer housing through the second bolt 15, and at the same time, the double oil seals 14 are used to prevent the leakage of the gear oil inside the gearbox housing.

[0023] The gear pump 8 rotates, and when the gear pump 8 rotates, it generates pressure to drive the entire circulation of the gear oil.

[0024] The above are only the embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
