The additives in gear oil mainly include cleaning and sloppy agents, antioxidant and antiseptic agents, anti-wear agents, oily agents, etc.
Purifying and dispersing agent: adsorbs oxidation products and disperses them in oil, mainly composed of planktonic components, which have the functions of anti-oxidation and anti-corrosion.
Antioxidant and anti-preservative: This additive can improve the oxidation safety of oil, avoid metal oxidation, catalyze the oxidation rate of obsolete oil, isolate the contact between acids and metals to form a maintenance film, and also have anti-wear properties.
Anti-wear agent: The high-temperature part of the friction surface can react with the metal to form a substance with a low melting point, thus acting as an anti-wear agent.
Oil-based agents: These are active substances with polar molecules, which can form a robust adsorption film on the metal surface, avoid direct contact with the metal friction surface, and reduce friction and wear.
In addition, extreme pressure anti-wear agents are often added to gear oils, and their main function is to prevent tooth surface abrasion, sintering and wear. Extreme pressure anti-wear agents are mostly additives containing active elements such as sulfur, phosphorus and chlorine, such as sulfide isobutylene, phosphate esters and chlorinated paraffins.
Please note that the exact type and amount of these additives may vary depending on the type of gear oil and the application. When selecting and using a gear oil, it is advisable to choose the right gear oil according to the recommendations of the equipment manufacturer and the specific conditions of use.
