Guide to Industrial Gear Oil
In industrial production, industrial gear oil plays a crucial role. It is like the "blood" of mechanical equipment, providing lubrication, cooling, anti - corrosion and multiple other protections for various gear transmission systems, ensuring the efficient and stable operation of equipment.
What is Industrial Gear Oil?
Industrial gear oil is a type of lubricating oil used in the gear transmission systems of industrial equipment. Its main functions are to reduce friction and wear on gear surfaces, lower energy consumption, prevent gears from rusting and corroding, and carry away the heat generated by friction. This extends the service life of gears and ensures the normal operation of equipment.
The Functions and Application Scenarios of Industrial Gear Oil
Functions：
-Lubrication and Anti-wear
Forms an oil film during gear meshing, reducing direct contact between tooth surfaces, lowering the friction coefficient, making gear operation smoother, reducing wear, and extending the gear's lifespan.
-Cooling and Heat Dissipation
A large amount of heat is generated when gears operate at high speeds. Industrial gear oil can carry away this heat, preventing gears from being damaged by overheating and maintaining the normal temperature range of the gear system.
-Rust and Corrosion Prevention
Protects gear surfaces from the erosion of moisture, oxygen, and other corrosive substances, preventing rust and corrosion, and ensuring the accuracy and strength of gears.
-Anti-wear and Extreme Pressure Resistance
Under heavy - load or shock - load conditions, it can form a strong protective film on the gear surface, preventing direct metal - to - metal contact and avoiding tooth surface scuffing, galling, and other damages.
-Buffering and Vibration Damping
Absorbs and disperses the impact and vibration during gear transmission, reducing noise and improving the operational stability of the gear system.
Application Scenarios
-Metallurgical Industry
Gear transmission systems of equipment such as rolling mills and continuous casting machines face harsh working conditions such as high temperatures, heavy loads, and dust. They have extremely high requirements for the extreme - pressure anti - wear, anti - oxidation, and anti - pollution performance of gear oil.
-Mining Machinery
Gearboxes of equipment such as crushers, ball mills, and elevators work in harsh environments with a lot of dust. Gear oil is required to have good anti - wear, rust - prevention, and anti - emulsification properties to cope with high - load impacts and harsh environmental conditions.
-Cement and Building Materials Industry
Gear transmission devices of equipment such as cement rotary kilns, ball mills, and crushers operate under high temperatures and heavy loads. Gear oil is required to have excellent high - temperature resistance, anti - oxidation performance, and extreme - pressure anti - wear performance to ensure the long - term stable operation of the equipment.
-Power Industry
Gearboxes of equipment such as wind turbines, coal mills in thermal power plants, and induced draft fans need gear oil to provide good lubrication and protection under different environmental temperatures. At the same time, it should have a long lifespan and anti - micropitting performance to adapt to the long - term continuous operation and complex working conditions of the equipment.
-Shipping Industry
Gear transmission systems of equipment such as ship main propellers, cranes, and windlasses work in a humid and high - salt environment. There are strict requirements for the rust - prevention, anti - emulsification, and anti - foaming properties of gear oil to prevent gears from rusting, corroding, and having poor lubrication.
How to Select Additives for Industrial Gear Oil?
The performance of industrial gear oil depends to a large extent on the additives added. Additives can endow gear oil with special properties to meet the requirements of different working conditions.
The common types of additives and their functions are as follows:
Extreme-Pressure Anti-wear Additives: Compounds containing elements such as sulfur, phosphorus, and chlorine. Under heavy - load and shock - load conditions, they react with the metal surface to form a chemical reaction film, preventing tooth surface scuffing and galling, and improving the load - bearing capacity and anti - wear performance of gear oil.
Antioxidants: Delay the oxidative deterioration of gear oil during use and extend its service life. By inhibiting the occurrence of oxidation reactions, they reduce the formation of oxidation products such as sludge and varnish, maintaining the cleanliness and performance stability of gear oil.
Rust Inhibitors: Prevent gear surfaces from rusting. They form an adsorption film or chemical reaction film on the metal surface, isolating moisture and oxygen and protecting gears from corrosion. This is especially suitable for working environments with moisture or water contact.
Anti - emulsifiers: Enable the water mixed in the gear oil to separate quickly, preventing the formation of an emulsion and ensuring the lubrication performance of gear oil. In working conditions with water pollution, such as the mining machinery and cement and building materials industries, anti - emulsifiers are particularly important.
Anti - foaming Agents: Reduce the tendency of gear oil to generate foam during the stirring process, making the foam break and disappear quickly. Excessive foam can affect the lubrication and heat - dissipation performance of gear oil, and even cause problems such as oil pump cavitation.
