The most important task of an open gear lubricant is to prevent metal-to-metal contact and reduce friction. Other important tasks include protecting the teeth against corrosion and abrasion, increasing the dynamic load-bearing capacity of the system, preventing damage such as scratches, cavities, softening of the tooth surface, and increased contact ratio.
To achieve the above, a suitable lubricant must have specific properties such as being free of any solvents, bitumen, heavy metals and chlorine, appropriate behavior at different temperatures, low self-combustion risk, low evaporation loss and easy lubricant disposal. Operate from the surface of the teeth.
