Gear oil and butter are two common lubricants on vehicles, both of which can play a role in lubrication, anti-wear, etc. Can the two be mixed? The answer is no, because gear oil and butter are two completely different lubricants.
Gear oil is essentially a kind of lubricating oil, which is mainly based on petroleum lubricating oil base oil or synthetic lubricating oil, and is made of extreme pressure anti-wear agent and oily agent, which has excellent wear resistance, load resistance, thermal oxidation stability, foaming resistance, water separation performance and anti-rust performance, and is mainly used for various gear transmission devices, such as transmissions, differentials, and drive axles, which can prevent tooth surface wear and sintering, prolong the service life of gears, and improve transmission power efficiency.
The role of gear oil:
1. Lubrication, anti-wear and anti-rust: gear oil can reduce the friction between gears and other moving parts, reduce and reduce wear, and the anti-wear agents and anti-rust agents contained in it can effectively prevent the loss of gears under high load or long-term operation, protect the metal surface from corrosion and oxidation, and prolong its service life.
2. Heat dissipation: The gear is easy to generate a lot of heat during the rotation process, and the gear oil can continuously take away the heat in the process of circulating lubrication, and dissipate it through the air or shell to ensure the stable work of the parts.
3. Improve transmission efficiency: A variety of additives such as extreme pressure anti-wear agent and oily agent are added to the composition of gear oil, which can reduce friction and loss inside the transmission system, improve transmission efficiency, and help improve the performance and economy of the vehicle.
4. Shock absorption and noise reduction: Gear oil can reduce the working noise of parts, reduce and reduce the impact between gears, and improve driving comfort and safety.
5. Cleaning function: The gear oil also has the ability to clean dirt, which plays a certain role in scouring the dirt on the tooth surface and further reduces the loss of the gear.
Butter is a semi-solid grease, mainly made of mineral oil (or synthetic lubricating oil) and thickeners, which can reduce friction, loss and corrosion between mechanical parts, ensure the quality and performance of parts, prolong the service life of parts, and ensure driving safety. The position of the truck to butter is generally in the I-beam lifting lug, steering ball head, front axle and rear axle bearing, transmission shaft, cross shaft and direction tie rod.
The role of butter:
1. Lubrication: Butter can form a lubricating film between parts to prevent direct contact between parts and reduce friction resistance.
2. Cooling: Butter can absorb the heat generated when the parts are working and maintain the working temperature of the parts.
3. Sealing: During use, butter will fill the sealing gap in the form of liquid, forming a layer of lubricating film, acting as an oil seal and playing the role of sealing.
4. Cleaning: The sediment generated by the work of the parts can be cleaned to keep the inside of the parts clean.
5. Anti-rust and anti-corrosion: anti-oxidants and corrosion inhibitors in butter can prevent oxidation and corrosion when metal parts are in contact with air, and maintain equipment performance and quality.
Therefore, there are differences between gear oil and butter in terms of viscosity, composition and specific function, and they cannot be substituted or blended together under normal circumstances. However, in rare cases, such as oil leakage after filling gear oil with some parts, a small amount of butter can be added to prevent oil leakage.
