The core lubrication method of ZSC (A) 400-24.9-2 medium hard tooth surface reducer is oil bath lubrication (splash lubrication). The regular oil change interval is 200~300 hours for the first operation, and every 2000~3000 hours or once a year thereafter.
1. Main lubrication methods
Core method: oil bath lubrication (splash lubrication) , the gear is immersed in the lubricating oil pool, and when rotating, the oil is brought up to form an oil film, which lubricates key parts such as the meshing surface and bearings.
Supplementary scenario: If the installation angle of the reducer is >15°, continuous heavy load or high temperature environment, forced circulation lubrication (external oil pump) can be used to improve lubrication uniformity.
Lubricating oil selection: commonly used 220# and 320# medium-load industrial gear oil (GB 5903 standard), 150# can be selected for low temperature environments, and 460# can be selected for high temperature and heavy loads.
2. Standard oil change interval
First oil change: After the new reducer has been running for 200 to 300 hours , it needs to be replaced in time to remove metal debris generated during the running-in period.
Routine oil change: Under normal working conditions (temperature ≤80°C, light to moderate load), every 2000~3000 hours or once a year , whichever comes first.
Special working conditions adjustment: When the oil temperature is high (oil temperature > 90°C), there is a lot of dust, frequent starts and stops, or heavy load impact, the oil change cycle is shortened by 30% to 50%; when the oil is emulsified, smells, and impurities exceed the standard, it needs to be replaced immediately.
3. Key matters needing attention
Oil level control: Add oil to the center line of the oil window to avoid excessive oil level, which increases energy consumption, and excessive oil level, which causes insufficient lubrication.
Oil change operation: Drain the oil after stopping the machine to cool down, thoroughly clean the impurities at the bottom of the oil tank, and then add new oil to the specified level.
Compatibility: Gear oils of different brands and models cannot be mixed. When changing oil brands, the oil tank must be thoroughly cleaned.
