Without knowing the characteristics of lubricating oil of planetary reducer, adding lubricating oil at will not only can not lubricate planetary gearbox and protect gears, but also can reduce the efficiency of reducer, increase wear power consumption of planetary reducer and indirectly reduce the service life of gearbox. Therefore, only by understanding the lubricating oil characteristics of the planetary gear reducer, can the planetary gearbox be better maintained and maintained.
1. Good wear resistance
Wear resistance refers to the ability of lubricating oil of speed reducer to form and maintain oil film on the friction surface between moving parts, prevent metal from contacting each other and reduce wear. The abrasion resistance of planetary reduction gearbox lubricating oil mainly depends on oil and extreme pressure (shear resistance).
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 on the friction surface is very high and the oil film is prone to rupture. It is also called load-carrying capacity.

2. Viscosity and Viscosity-Temperature
The lubricating oil of planetary gearbox unit must have proper viscosity and good viscosity-temperature property.
Generally speaking, the use of high viscosity lubricants is beneficial to prevent damage and reduce noise, while low viscosity lubricants are better in transmission efficiency, cooling effect and oil transmission.
For viscous-temperature performance, reducer lubricants do not change as much as engine oil, but because of the great pressure on the tooth surface, good viscous-temperature performance is also required, especially in cold areas. Otherwise, the wear and tear will be aggravated and the fuel consumption will be increased.
