Description

Technical Field

[0001] This utility model belongs to the field of high-speed gearboxes, specifically a high-speed gearbox that can be rapidly cooled. Background Technology

[0002] A high-speed gearbox is a mechanical device used to transmit power and regulate speed. It typically consists of a series of gears that transmit power through meshing and can convert the speed of the input shaft into the required speed of the output shaft. It is usually used to meet the needs of high-speed operation and high power output.

[0003] According to Chinese Patent Application No. 202121022229.7, a high-speed rolling gearbox with a cooling device is disclosed, including a gearbox housing and a finned tube radiator disposed on the outer left side of the gearbox housing. The lubricating oil outlet and lubricating oil inlet of the finned tube radiator are respectively connected to the gearbox housing and an oil pump through oil pipes. The middle part of the finned tube radiator is connected to the gearbox housing through a support rod. A rocking mechanism for shaking the finned tube radiator is provided at the bottom of the gearbox housing. By using the output shaft in the gearbox in conjunction with the rocking mechanism, the finned tube radiator is made to swing, thereby making the lubricating oil contact the heat dissipation fins inside the finned tube radiator more fully, thereby improving the heat dissipation efficiency.

[0004] Existing technologies have effectively solved the problem of low cooling effect in high-speed gearboxes and have the advantage of improving the heat dissipation efficiency of high-speed gears. However, the finned tube radiator is affected by the temperature of the lubricating oil during long-term use, and its own temperature will also rise, thereby reducing the cooling effect of the lubricating oil. Moreover, the friction between gears inside the gearbox will generate debris, which will mix with the lubricating oil to form sludge that enters the radiator, which can easily cause blockage of the radiator and thus affect the cooling effect of lubrication.

[0005] In summary, this invention provides a high-speed gearbox that can be rapidly cooled to solve the above-mentioned problems. Utility Model Content

[0022] Example 1

[0023] like Figure 1-4As shown, this is the first embodiment of the present invention. This embodiment provides a high-speed gearbox with rapid cooling, including a gearbox assembly 1. The gearbox assembly 1 includes a lower housing 101, an upper housing 102, and an oil inlet 103. The lower housing 101 and the upper housing 102 together provide protection for the gear set. The oil inlet 103 is used to add lubricating oil. A cooling assembly 2 is provided on the back of the gearbox assembly 1. The cooling assembly 2 includes a frame 201, a finned tube radiator 202, and a fan 203. The finned tube radiator 202 is used to cool the lubricating oil, and the fan 203 is used to cool the finned tube radiator 202. A circulation assembly 3 is provided on one side of the gearbox assembly 1. The circulation assembly 3 is used to circulate the lubricating oil. A filter assembly 4 is also provided on one side of the gearbox assembly 1. The filter assembly 4 includes a cylinder 401, a connecting ring 402, a filter element 403, and a connecting pipe 404. The filter assembly 4 is used to filter the lubricating oil.

[0024] like Figure 1-4 As shown, the combination of the lower housing 101 and the upper housing 102 provides support and protection for the gears. Lubricating oil can be added through the oil inlet 103. The lubricating oil in the inner cavity of the lower housing 101 is filtered by the filter element 403 and then transported to the inner cavity of the finned tube radiator 202 through the circulation assembly 3 for cooling. The connecting ring 402 and the cylinder 401 provide installation space for the filter element 403. The filter element 403 can be cleaned or replaced by removing the connecting ring 402 from the surface of the cylinder 401, thereby preventing sludge from clogging the finned tube radiator 202 and affecting the cooling effect. After the finned tube radiator 202 cools the lubricating oil, it flows back to the inner cavity of the lower housing 101 through the return pipe 204 for lubrication. The airflow generated by the fan 203 can cool the finned tube radiator 202, thereby improving the cooling effect of the high-speed gearbox.

[0025] Example 2

[0026] Reference Figure 1-3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0027] In this embodiment, the upper housing 102 is located on top of the lower housing 101 and is movably connected to the lower housing 101 by bolts, and the oil inlet 103 is located on top of the upper housing 102.

[0028] The finned tube heat sink 202 is installed inside the frame 201, and the fan 203 is installed on the back of the frame 201.

[0029] The cooling assembly 2 also includes a return pipe 204, one end of which is connected to the outlet of the finned tube radiator 202, and the other end of which is connected to the inner cavity of the upper housing 102.

[0030] like Figure 1-3As shown, the combination of the lower housing 101 and the upper housing 102 provides support and protection for the gears. Lubricating oil can be added through the oil inlet 103. The lubricating oil in the inner cavity of the lower housing 101 is filtered by the filter assembly 4 and then transported to the inner cavity of the finned tube radiator 202 through the circulation assembly 3 for cooling. The cooled lubricating oil flows back to the inner cavity of the lower housing 101 through the return pipe 204 to continue lubricating the gears. The frame 201 provides support for the finned tube radiator 202 and the fan 203. The airflow generated by the high-speed rotation of the fan 203 can cool the finned tube radiator 202, thereby improving the cooling effect of the lubricating oil and enabling the high-speed gearbox to cool down quickly.

[0031] Example 3

[0032] Reference Figure 1 , 2 4 and 5 are the third embodiment of this utility model, which is based on the first two embodiments.

[0033] In this embodiment, the circulation component 3 includes an oil pump 301, an oil outlet pipe 302, and a guide pipe 303. One end of the oil outlet pipe 302 is connected to the outlet of the oil pump 301, and the other end of the oil outlet pipe 302 is connected to the inlet of the finned tube radiator 202. One end of the guide pipe 303 is connected to the inlet of the oil pump 301.

[0034] One end of the connecting pipe 404 is connected to the lower housing 101. There are two connecting rings 402, which are located on both sides of the cylinder 401 and are threadedly connected to the cylinder 401. One side of the connecting ring 402 is sleeved on the surface of the connecting pipe 404. The other end of the guide pipe 303 is connected to the other side of the connecting ring 402. The filter element 403 is located in the inner cavity of the cylinder 401 and is movably connected to the inner cavity of the cylinder 401.

[0035] like Figure 1 , 2 As shown in Figure 4, the lubricating oil in the inner cavity of the lower housing 101 is guided to the inner cavity of the cylinder 401 through the connecting pipe 404. The filter element 403 can filter the lubricating oil in the inner cavity of the cylinder 401 and separate the sludge from the lubricating oil, thereby preventing the sludge from clogging the finned tube radiator 202. The filtered lubricating oil enters the inner cavity of the oil pump 301. The oil pump 301 generates thrust on the lubricating oil, which is then transported through the oil outlet pipe 302 to the inner cavity of the finned tube radiator 202 for cooling. The cooled lubricating oil flows back to the inner cavity of the lower housing 101 through the return pipe 204 to continue lubricating the gears. By rotating the connecting ring 402, the connecting ring 402 is dislodged from the surface of the cylinder 401, and the filter element 403 can be removed for replacement or cleaning.

[0036] During use, the lubricating oil in the inner cavity of the lower housing 101 is guided to the inner cavity of the cylinder 401 through the connecting pipe 404. The filter element 403 can filter the lubricating oil in the inner cavity of the cylinder 401, separating the sludge from the lubricating oil, thereby preventing the sludge from clogging the finned tube radiator 202. The filtered lubricating oil enters the inner cavity of the oil pump 301, and the oil pump 301 generates thrust on the lubricating oil, which is then transported through the oil outlet pipe 302 to the inner cavity of the finned tube radiator 202 for cooling. The airflow generated by the high-speed rotation of the fan 203 can cool the finned tube radiator 202, thereby improving the cooling effect of the lubricating oil. The cooled lubricating oil flows back to the inner cavity of the lower housing 101 through the return pipe 204 to continue lubricating the gears. By rotating the connecting ring 402, the connecting ring 402 is dislodged from the surface of the cylinder 401, and the filter element 403 can be removed for replacement or cleaning.
