Performance characteristics of reducer lubricating oil
1.It has good anti-wear properties. Anti-wear properties mean that the reducer lubricating oil forms and maintains an oil film on the friction surface between the moving parts, preventing the metals from contacting each other and reducing wear and tear.
Ability.The wear resistance of the reducer lubricating oil mainly depends on the oil property and extreme pressure (shear resistance).Oiliness refers to the ability of gear oil to adsorb 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 its adsorption capacity is strong, which can improve the ability of anti-wear.Extreme pressure refers to the performance of preventing sintering, gluing and other damage to the friction surface under 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 bearing capacity.
2.Viscosity and viscosity-temperature lubricating oil must have suitable viscosity and good viscosity-temperature.Generally speaking, the use of high-viscosity lubricating oil is beneficial to prevent mechanical damage and reduce noise, while low-viscosity lubricating oil is better in terms of transmission efficiency, cooling effect and oil transferability.Regarding the viscosity-temperature performance, the reducer lubricating oil does not have the same temperature change as the engine oil, but due to its high pressure on the tooth surface, it also requires good viscosity-temperature performance, especially when used in cold areas.Otherwise, the wear and tear will increase and the fuel consumption will increase.
3.Oxidation stability The lubricating oil of the reducer is stirred by the movement of the gear and constantly in contact with oxygen, forming various oxides under the catalytic action of the metal, which increases the viscosity of the lubricating oil, darkens the color, increases the acid value, and precipitates The amount of material increases, the color becomes darker, and causes corrosion to the parts, resulting in poor anti-foaming and anti-oxidation properties of the lubricating oil, so the lubricating oil has to be replaced.The lubricating oil with good oxidation stability has a long service life.Therefore, antioxidants are usually added to lubricating oils to improve oxidative stability.
4.Anti-rust and anti-corrosion Anti-rust refers to the performance of reducer lubricating oil to prevent metal from rusting.Corrosion resistance refers to the performance of gear oils against metal corrosion.The rusting 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.Anti-rust additives and anti-corrosion additives are usually added to the reducer lubricating oil to improve.
5.Anti-foaming reducer oil will generate many small air bubbles under intense stirring during gear movement.If the small bubbles disappear quickly, it will not affect the use.If the stable foam is formed and no longer disappears and emulsification and deterioration occur, overflow will occur on the tooth surface, destroy the lubricating oil film, and aggravate the wear.
