[0025] As shown in the steps of the method, after the gearbox is clamped, the running-in cleaning test is completed according to the steps of Figure 2 and Figure 3 . Step 1, build a network communication environment, clamp the gearbox on the test bench, and determine whether the gearbox is clamped. If the gearbox is not clamped, send a warning message to the host computer through the CAN network communication to warn the staff, so that the staff can re-clamp the gearbox. If the gearbox is clamped, execute step 2. Step 2, the host computer obtains the specification information of the gearbox, extracts the corresponding execution file based on the specification information, and the execution file contains the specification and model of the current gearbox to be provided with power supply data, air pressure data, and lubricating oil parameters. According to the execution file, build test conditions on the gearbox, that is, connect 24V DC power supply on the gearbox, start to input compressed gas and add lubricating oil. Step 3, the host computer sends a test signal to the gearbox TCU, and the gearbox TCU determines whether the test conditions are met based on the test signal.

[0027] Step 5, after 10 minutes of running-in and cleaning, the host computer obtains the cleanliness information of the lubricating oil, and judges whether the cleanliness of the lubricating oil is qualified, if the cleanliness is unqualified, the detection is re-detected once, if the cleanliness is still unqualified, the return to repair is carried out, if the cleanliness is qualified, the qualified mark is made, and the test is ended.

[0028] After the detection is ended, a detection report is generated, the detection report includes the cleanliness data of the lubricating oil, the running-in state after the cleaning, and the number of the gearbox, and is uploaded to the host computer for display and storage.
