Cleaning method

• External cleaning
  • Firstly, the power should be cut off before cleaning, and cleaning should begin after the gearbox has stopped running and completely cooled down to ensure safe operation and prevent electric shock and burns.
  • Use a clean cloth or soft bristled brush to gently wipe the outer shell of the gearbox, removing surface dust, oil stains, and other dirt. For difficult to remove stains, a small amount of mild cleaner (such as a mixture of detergent and water) can be used, but it is important to avoid the cleaner from entering the interior of the gearbox.
  • Pay attention to cleaning the cooling fins of the gearbox (if any) to ensure that the gaps between the fins are not blocked by dust or debris, as good heat dissipation is crucial for the normal operation of the gearbox.
• Internal cleaning (requires careful operation)
  • In general, it is not recommended for users to disassemble the gearbox for internal cleaning on their own, unless they are professional maintenance personnel. If it is necessary to open the gearbox for cleaning, the position and connection method of each component should be marked according to the equipment's user manual before disassembly.
  • Internal cleaning mainly involves removing old lubricating oil, metal shavings, and other impurities accumulated on components such as gears and bearings. You can use specialized cleaning solvents (such as kerosene or specialized gearbox cleaning agents) to soak the components in the solvent, and then gently brush them with a soft bristled brush. After cleaning, ensure that the components are completely dry and avoid any residual solvents reacting with newly added lubricating oil.

Maintenance Method

• Inspection and replacement of lubricating oil
  • Regularly checking the level of lubricating oil is a crucial maintenance step. Check the oil level through the oil level observation window or oil level gauge on the gearbox to ensure that the oil level is within the normal range. If the oil level is too low, it may cause insufficient lubrication of gears and bearings, accelerating wear.
  • Different models of mixing reducers have different requirements for the type and replacement cycle of lubricating oil, which are generally determined according to the equipment's user manual. Normally, after a certain period of operation (such as 100-500 hours), it is necessary to replace the oil with a new one, and then replace it every certain period of operation (such as 1000-5000 hours) thereafter. When replacing lubricating oil, the old oil should be completely drained and a clean container should be used to hold the new oil to prevent impurities from entering.
• Inspection of gears and bearings
  • Regularly check the wear of gears. Slight wear is normal, but if severe wear, peeling, or cracks are found on the gear tooth surface, it is necessary to replace the gear in a timely manner. The inspection method can be through visual observation or using some simple measuring tools (such as calipers) to measure the tooth thickness of the gear.
  • For bearings, check for looseness, abnormal noise, or overheating. A normal bearing should operate smoothly and quietly. If any problems are found with the bearings, they should be replaced in a timely manner to avoid the expansion of the fault.
  • Check if the seals are intact. The function of the seal is to prevent lubricating oil leakage and external impurities from entering the interior of the gearbox. If the seal is damaged, it should be replaced in a timely manner to ensure the cleanliness of the gearbox and the normal storage of lubricating oil.
• Regular no-load operation inspection
  • Regularly running the mixing reducer under no-load conditions for a period of time (such as once a month for 10-30 minutes) can help identify potential issues such as abnormal noise, vibration, etc. During no-load operation, carefully observe the operating status of the gearbox, including the operation of the motor, the meshing sound of the gears, etc. If any abnormalities are found, the machine should be stopped for inspection in a timely manner, and the fault should be eliminated before putting it back into use.
