During the operation of the planetary reducer, adding lubricant and replacing it is a necessity. Some manufacturers add lubricant at the time of manufacture. However, whether lubricant has been added or not, it is necessary to replace it after some time of use; the planetary reducer is an exception to this. What if lubricant is forgotten or not replaced?

What happens if you forget to change the reducer's lubricating oil? For reducer combinations with higher output or input speeds, long-term high-speed operation can increase friction, leading to greater heat generation. In this case, new lubricating oil can reduce friction and prevent more heat from being produced. However, if the lubricating oil is not changed for a long time and operates at high speed, it becomes thick and may contain impurities. This situation may result in two outcomes: abnormal noise and temperature rise.

Lubricants thickening and containing impurities accelerate the wear between gears, which can lead to gear meshing issues. As the impurities accumulate, their impact on the gears intensifies, causing abnormal noises, which may be uneven.

Additionally, the temperature increase is due to the increased friction, which in turn causes a rise in temperature. With only one ventilation hole, and it not being particularly large, the heat generated internally due to friction is not able to be expelled in time, leading to a continuous accumulation of rising temperatures.

After 2,000 hours of use, it's advisable to inspect the internal condition. If the internal lubricant is too thick and hinders the operation of gears or worm gears, a replacement is necessary.
