For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following is an explanation of the embodiments of the present utility model based on the overall structure of the present utility model.

[0024] Reference Figures 1 to 7 In the embodiment of the utility model, a gearbox with a lubrication mechanism includes: a fixed bracket 2 is fixedly arranged at one end below the lubricating oil tank 1, a gearbox 3 is fixedly arranged below the fixed bracket 2, a support bracket 4 is fixedly arranged at one end inside the lubricating oil tank 1, a support seat 5 is fixedly arranged inside the support bracket 4, a screw 6 is screwed on the top of the support seat 5, and a filter cartridge 7 is fixedly arranged above the screw 6. The combination of the support bracket 4 and the support seat 5 provides a stable installation platform for the filter cartridge 7 to ensure that it will not shake or shift during operation, thereby ensuring the stability and reliability of the filtering effect, a micro oil pump 12 is fixedly arranged at the middle position below the lubricating oil tank 1, and an oil delivery pipe 13 is fixedly connected below the micro oil pump 12. The micro oil pump 12 transports the filtered lubricating oil to the inside of the gearbox 3 through the oil delivery pipe 13, thereby realizing the automatic circulation and supply of the lubricating oil and improving the lubrication efficiency and performance of the gearbox.

[0025] A heat absorption box 14 is inserted into one side of the oil pipeline 13. The heat absorption box 14 is fixedly arranged at one end above the gearbox 3. A refrigeration device 15 is fixedly arranged above the heat absorption box 14. Through the coordinated use of the heat absorption box 14 and the refrigeration device 15, the lubricating oil in the oil pipeline 13 is cooled in real time to prevent the lubricating oil from deteriorating or reducing the lubrication effect due to high temperature. The cold liquid input pipe 16 introduces coolant to cool the lubricating oil, and the hot liquid recovery pipe 17 recovers the heated coolant, thereby realizing the recycling of the coolant and improving the energy utilization efficiency.

[0026] A speed gear set 20 is rotatably arranged inside the gearbox 3, and an injector 21 is fixedly arranged on the upper inner side of the gearbox 3. The speed gear set 20 inside the gearbox 3 is the core component of the transmission system, and its lubrication effect directly affects the transmission efficiency and performance of the gearbox. The lubricating oil is evenly sprayed on the gear set through the injector 21, ensuring good lubrication and heat dissipation of the gear set.

[0027] The filter ring plate 10 is attached to the outer surface of the hollow ring plate 11 and is fixed to the inner side of the oil overflow cylinder 9 to form an effective filtering layer. The design of the oil overflow groove enables the lubricating oil to flow smoothly during the filtration process, thereby improving the filtration efficiency.

[0028] The oil delivery pipe 13 passes through the heat absorption box 14, and the inside of the refrigeration device 15 is filled with coolant to cool the lubricating oil inside the oil delivery pipe 13, so that the lubricating oil can be cooled by the refrigeration device 15 during transportation, thereby reducing the temperature of the lubricating oil and improving its lubrication performance and stability.

[0029] An inlet is provided on the side of the oil collecting tank 23 to facilitate the discharge of waste oil from the oil drain ramp 22. An oil drain nozzle is fixedly arranged below the oil collecting tank 23. The inlet on the side of the oil collecting tank 23 facilitates the discharge of waste oil from the oil drain ramp 22, and the oil drain nozzle below the oil collecting tank facilitates the discharge and treatment of waste oil, thereby maintaining the cleanliness and lubrication effect of the inside of the gearbox.

[0030] The working principle of the utility model is as follows: first, lubricating oil is added through the oil inlet hole above the lubricating oil tank 1, and the lubricating oil enters the oil overflow cylinder 9 through the hollow ring plate 11. In the oil overflow cylinder 9, the lubricating oil is filtered by the filter ring plate 10, and continues to flow downward after impurities are removed. Since there is an oil overflow groove with a gap between the filter ring plate 10 and the inner side of the oil overflow cylinder 9, and after the oil overflow groove is full, the lubricating oil can smoothly flow into the oil drain groove between the filter cylinder 7 and the oil overflow cylinder 9, and then, the lubricating oil flows out through the oil outlet hole 8 below the filter cylinder 7, ready to enter the lubrication system, the filter cylinder 7 is screwed to the support seat 5 through the screw 6, and the filter cylinder 7 can be quickly taken out of the lubricating oil tank 1, and the filter ring plate 10 is replaced. After the micro oil pump 12 is started, the filtered lubricating oil is extracted and transported to the top of the gearbox 3 through the oil pipe 13. During the transportation process of the oil pipe 13, the lubricating oil first passes through the heat absorption box 14, and a heat absorption box 14 is arranged above the heat absorption box 14. There is a refrigeration device 15, which introduces coolant through the cold liquid inlet pipe 16 to cool the lubricating oil in the oil pipe 13, and then the hot liquid is discharged through the hot liquid recovery pipe 17 to realize the recycling of the coolant. At the same time, the coolant tank 18 replenishes the coolant for the refrigeration device 15 through the replenishing pipe 19 to ensure a continuous and effective cooling effect. The cooled lubricating oil is finally evenly sprayed on the speed change gear set 20 inside the gearbox 3 through the injector 21 to achieve lubrication and cooling of the gear set. As the gearbox 3 runs, the lubricating oil gradually penetrates into various parts that need lubrication, and gradually heats up and is contaminated with impurities during use. Subsequently, the waste lubricating oil and impurities slide down the oil discharge inclined plate 22 under the action of gravity, and are collected through the inlet on the side of the oil collecting tank 23. The oil discharge nozzle below the oil collecting tank 23 can be used to regularly discharge waste oil so as to replace new lubricating oil and keep the inside of the gearbox 3 clean and lubricated.

[0031] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
