What are the characteristics of reducer lubricating oil?

1. Good wear resistance and wear resistance

Anti-wear performance refers to the ability of reducer lubricating oil to form and maintain an oil film on the friction surface between moving parts, prevent metal from contacting each other, and reduce wear.The anti-wear performance of reducer lubricating oil mainly depends on oiliness and extreme pressure (resistance).Oiliness refers to the ability of gear oil to absorb on the friction surface of parts to form an oil film to reduce friction and wear.Usually we say that the good oiliness of gear oil means that it has strong adsorption capacity and can improve the ability to resist wear.Extreme pressure refers to the performance of preventing damage to the friction surface such as sintering and gluing under the extremely high pressure lubrication conditions where the contact pressure of the friction surface is very high and the oil film is prone to rupture. It is also called the carrying capacity.

2. Viscosity and viscosity-temperature

Reducer lubricating oil must have suitable viscosity and good viscosity-temperature properties.Generally speaking, the use of high-viscosity lubricating oil is beneficial to prevent machine damage and reduce noise, while low-viscosity lubricating oil is better in terms of transmission efficiency, cooling effect, and oil transmission.Regarding the viscosity-temperature performance, although the reducer lubricating oil does not have such a large temperature change as the engine oil, due to the high pressure on the tooth surface, it also requires good viscosity-temperature performance, especially when used in cold regions.Otherwise, it will cause increased wear and increased fuel consumption.

3. Oxidation stability

The lubricating oil of the reducer is stirred by the gear movement and continuously contacted with oxygen, and various oxides are formed under the catalysis of the metal, which increases the viscosity of the lubricating oil, darkens the color, increases the acid value, and increases the sediment. The color becomes darker and causes corrosion of the machine parts, resulting in poor anti-foaming and oxidation resistance of the lubricating oil, so the lubricating oil has to be replaced.Lubricating oil with good oxidation stability has a long service life.Therefore, antioxidants are usually added to lubricating oils to improve oxidation stability.

4. Anti-rust and anti-corrosion properties

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.The rust of metal parts is mainly caused by the presence of oxygen and water in the lubricating oil.Corrosion is caused by acids and sulfides in the oil.Usually, anti-rust additives and anti-corrosion additives are added to the lubricating oil of the reducer to improve

5. Anti-foam
