Performance characteristics of reducer lubricating oil
1. Good wear resistance
Wear resistance refers to the ability of reducer lubricating oil to form and maintain oil film on the friction surface between moving parts, prevent metal to metal contact and reduce wear. The wear resistance of reducer lubricating oil mainly depends on oiliness and extreme pressure (shear resistance).
2. Viscosity and viscosity temperature
Reducer lubricating oil must have appropriate viscosity and good viscosity temperature property.
As for the viscosity temperature performance, although the reducer lubricating oil does not have the large temperature change as the engine oil, it is also required to have good viscosity temperature performance because of its large tooth surface pressure, especially when used in cold areas. Otherwise, the wear will increase and the fuel consumption will increase.
3. Oxidation stability
Lubricating oil with good oxidation stability has a long service life. Therefore, antioxidants are usually added to lubricating oil to improve oxidation stability.
4. Rust and corrosion resistance
Rust resistance refers to the performance of reducer lubricating oil to prevent metal from rusting.
Corrosion resistance refers to the performance of gear oil to prevent metal corrosion.
5. Foam resistance
The reducer lubricating oil will produce many small bubbles under the intense stirring during gear movement. If small bubbles disappear soon, it will not affect the use. If the stable foam does not disappear and emulsification deterioration occurs, overflow will occur on the tooth surface, damaging the lubricating oil film and intensifying wear.
