Internal cleaning steps of ZSC600-77.5-4 medium hard tooth surface reducer:
1. Stop the machine and cut off the power, take safety precautions, clean the dust and oil on the outside of the reducer to prevent impurities from entering the inside during disassembly.
2. Open the oil drain plug at the bottom to completely drain out the old lubricating oil, sludge and impurities in the box. In winter, it can be properly preheated to facilitate oil draining.
3. Disassemble the reducer upper cover, bearing end cover, gear shaft assembly, oil seal and sealing gasket in sequence, place them in order and mark them to avoid collision and damage to the tooth surface.
4. Use industrial kerosene or neutral gear cleaning agent to soak and clean the box body, gears at all levels, bearings, shafts, end covers and other components. Use a soft-bristled brush to clean the sludge and metal debris. It is prohibited to use a wire brush to directly brush the medium-hard tooth surfaces.
5. Rinse each component twice with a clean cleaning agent to remove residual dirt, and then completely dry all components with oil-free and water-free compressed air, focusing on drying the gear tooth grooves, bearing raceways, and dead corners of the box.
6. Check the cleaned parts to ensure that there are no impurities and moisture residues, and that there is no obvious wear or corrosion on key parts such as gears, bearings, and journals.
7. Before reassembly, purge and wipe the inside of the box and all parts again. After confirming that they are clean, assemble according to the marked order. Replace with new sealing gaskets and oil seals to prevent impurities from being brought in during assembly.
8. After assembly is completed, add qualified new lubricating oil to complete the entire internal cleaning process.
