How long does it take to run in after the cwu63-6.3-Ⅲ reducer shaft is repaired for wear?

CWU63-6.3-Ⅲ is a small arc cylindrical worm reducer. After the journal is repaired (such as spraying, repair welding, brush plating, inlaid sleeve, etc.), the standard running-in time is recommended: 2 to 4 hours without load, 8 to 16 hours with light load, and the total running-in is not less than 10 to 20 hours, then it can run normally with rated load.

Specific running-in process

1. No-load running-in (2~4h)

Start it for the first time after repair, run continuously without load, and observe the oil temperature, noise, vibration and sealing for leaks. The temperature should gradually rise and stabilize.

2. Light load running-in (8~16h)

Load to 30% to 50% of the rated load and run continuously. At this stage, the main purpose is to gradually fit the mating surfaces of the shaft, bearing and oil seal to avoid excessive local stress.

3. Gradually load

After light-load running-in without abnormality, gradually increase the load to full load in 2 to 3 times, and run for 2 to 4 hours each time. After confirming that the temperature rise, noise, and sealing are normal, it can be put into normal use.

Things to note

If the repaired shaft has been welded, sprayed, etc., it must be cooled to room temperature before assembly to prevent secondary wear caused by thermal deformation.

During the running-in period, the oil temperature should not exceed 70°C. If it is too high, the machine should be stopped to check the coaxiality, lubrication and assembly tightness.

After running-in, it is recommended to check the oil quality and replace the lubricating oil if necessary to avoid wear debris from exacerbating internal wear.
