[0002] A gearbox run-in table is a device used for gearbox run-in testing. It typically consists of a table, motor, brake, universal joint, and other components. The motor provides power input to the gearbox's power shaft, while the brake simulates real-world operating conditions and applies load to the output shaft. This equipment allows the gearbox to be operated under specific operating conditions after assembly or repair, allowing internal components to be properly run-in and verifying performance. It also allows for testing various gearbox functions, such as acceleration, deceleration, and shifting, to promptly identify potential issues and ensure the quality and reliability of the gearbox.

[0003] Currently, most gearbox running-in tables are only used to test the quality of the gearbox. However, in this process, the metal debris generated by the wear of parts inside the gearbox is ignored, which affects the test results. At the same time, the gearbox oil temperature is too high after long-term operation, which affects the performance and service life of the gearbox. Therefore, we propose a gearbox running-in workbench with circulating oil purification and measurement and control effects. Summary of the Invention

There are two guide tubes 61, and the two guide tubes 61 are respectively fixedly connected to the side of the processing box 41 and the storage box 42 close to the table 1.

[0032] The working principle of the present invention is as follows: when performing the gearbox running-in test, the gearbox is placed on the placement plate 51 and mounted on the placement plate 51 and the mounting block 55 by means of bolts. Then, the telescopic rod 53 is controlled to push the placement plate 51 and the gearbox toward the drive motor 3. Then, the driving end of the drive motor 3 is connected to the input shaft of the gearbox via a coupling. Then, the oil extraction pipe 417 is connected to the oil drain port of the gearbox, and the oil drain pipe 419 is connected to the oil filling port of the gearbox. The cover 430 is opened, and a certain amount of gearbox oil is injected into the storage box 42 through the oil filling port 431. During maintenance, the gearbox is driven by the drive motor 3 to operate. After a period of running-in, the drive motor 3 is turned off, and the gearbox oil in the gearbox is extracted into the processing box 41 through the oil pump 414 and the oil pumping pipe 417. The pressure in the processing box 41 increases, and then the piston block 47 pushes the positioning plate 49 upward through the support rod 48, and the tension spring 410 is deformed under force, thereby storing the pressure. Then the gearbox oil in the processing box 41 flows into the first connecting pipe 423 through the first joint 422, and enters the filter cartridge 427 through the second one-way valve 424. At the same time, the spring pulls the positioning plate 49 downward, thereby driving the support rod 48 and the piston block 47 to move downward. The piston block 47 then applies pressure to the processing box 41 and pushes the gearbox oil again to ensure that the gearbox oil continues to enter the filter cartridge 427, completing the gearbox. After the oil is extracted, the oil extraction pump 414 is turned off, and the transmission oil in the storage box 42 is injected into the transmission through the oil discharge pump 418. At the same time, the pressure in the storage box 42 decreases, and the transmission oil in the filter cartridge 427 is sucked in through the second joint 426 and the second connecting pipe 425. Then, the transmission oil passes through the three filters 433 in sequence. During this process, the transmission oil pushes the filter screen 433 and the positioning ring 432 upward, and the compression spring 429 is deformed under force. At the same time, the compression spring 429 pushes the filter screen 433 and the positioning ring 432 downward, thereby accelerating the filtering operation of the transmission oil. Since the filter cartridge 427 is transparent, the user can observe the status of the transmission oil in time and analyze the running-in status of the transmission. The transmission oil after the process enters the storage box 42 through the second connecting pipe 425 and the second joint 426, completing the collection operation. When the warm gearbox oil enters the processing box 41 and the storage box 42, it first contacts the heat pipe 43, and the heat pipe 43 quickly absorbs the heat of the gearbox oil and conducts it to the fins 44. Then, the control motor 64 is turned on, and the control motor 64 drives the fan blades 65 to rotate. The fan blades 65 drive air to flow out quickly from the inside of the heat pipe 43. At the same time, the air drives the heat on the heat pipe 43 and the fins 44, and performs a heat dissipation operation on the heat pipe 43 and the fins 44. Because the fan blades 65 drive the air around the gearbox to flow quickly through the heat pipe 43, at the same time, the air on one side of the gearbox flows into the gearbox through the air guide cover 67 and the positioning frame 66, thereby synchronously performing a heat dissipation operation on the gearbox. After the gearbox oil is cooled, it is convenient to inject it into the gearbox again. Repeat the above operation, and the gearbox running-in operation can be continued; After the running-in operation is completed, the hook 412 is buckled on the stabilizing rod 411 to limit the displacement of the stabilizing rod 411, the support rod 48 and the piston block 47, and the gearbox oil in the gearbox is extracted by the oil pump 414. At this time, the gearbox oil is under pressure and directly enters the filter cartridge 427 for filtration. After all the gearbox oil is filtered, the gearbox oil enters the storage box 42 at the same time, the oil pump 414 is turned off, and then the oil extraction pipe 417 and the oil discharge pipe 419 are removed, and the first connecting pipe 423 and the second connecting pipe 425 are connected from the first joint 4 22 and the second joint 426, then unscrew the sealing cover 428, and pull the sealing cover 428 upward to pull out the compression spring 429, the positioning ring 432 and the filter screen 433, then pull the pull block 434 to pull out the filter screen 433, and clean or replace the filter screen 433, and then clean the filter cartridge 427. After completing the operation, put the compression spring 429, the positioning ring 432 and the filter screen 433 back into the filter cartridge 427, and screw on the sealing cover 428 again to facilitate the next operation of the equipment.
