What are the specific effects of excessive oil level in the KF87RF57-474-0.75KW reducer splash lubrication system on the equipment?

The impact of high oil level: significant oil mixing loss, temperature rise and leakage risk coexist.

When the oil level exceeds the upper limit of the standard, the gears are soaked too deeply, causing a series of chain problems:

1. Increased power loss in oil stirring: excessive stirring of lubricating oil during gear rotation consumes additional motor power and reduces transmission efficiency.

2. Rapid increase in oil temperature: Intense stirring of oil leads to increased friction within the oil, and the oil temperature can exceed 90 ℃ in a short period of time, causing a decrease in viscosity, weakened antioxidant capacity, and deteriorated lubrication performance of the lubricating oil.

3. Excessive pressure on the sealing system: An increase in oil mist and pressure inside the box can cause oil leakage from the oil seal and joint surface, especially in high temperature summer or continuous operating conditions.

4. Decreased cleanliness of lubricating oil: Excessive oil level may cause the return oil to bypass the filter tank and directly enter the oil tank, preventing impurities from effectively settling and increasing the risk of wear.

5. Foam tendency increases: violent agitation easily causes oil to carry air, forming foam, affecting oil film continuity and further weakening lubrication effect.
