Open gear lubricant product type
2014/8/19
1. Asphalt type and petroleum residue type products
Advantages: When the solvent is volatilized, a plastic-like rubber film is applied to the tooth surface to prevent wear, dust and water damage, and finally the purpose of protecting the gear. It has the characteristics of high bearing capacity and strong adhesion. Even under the worst operating conditions, it can form a high-strength and tough lubricating film on the surface of the exposed gear to prevent the wear of these friction pairs.
Disadvantages: poor viscosity temperature, easy to lose in summer, difficult to flow in winter, and solvent evaporation is not good for environment, safety and workers' health, and application is not easy. In developed countries in Europe and America, due to strict requirements of environmental regulations, such products The use of it is increasingly restricted and is gradually being discontinued.
2. Semi-fluid grease type products
A semi-fluid grease made from high-viscosity base oil, molybdenum disulfide, graphite and anti-high pressure additives. It contains no solvents harmful to the environment and human body.
Features:
● Maintains moderate consistency over a wide temperature range, excellent adhesion characteristics, good rust resistance, and strong water resistance even under high pressure.
● Choose the appropriate level of penetration, which can be applied to automatic spray devices to meet the needs of modern lubrication.
These products are currently the most widely used products in the market and usually have excellent extreme pressure and abrasion resistance, adhesion, water resistance and oxidation resistance. For example, Great Wall brand 7420 heavy duty open gear grease (use temperature range: -30 ° C ~ 120 ° C, can be used for painting, oil bath or spray lubrication), Great Wall brand universal open gear grease (application temperature: -15 ~120 ° C, hand smear or concentrated grease), Great Wall brand high temperature open gear grease HL (application temperature: -15 ° C ~ 180 ° C, hand smearing or concentrated grease) and other products.
3. Polymer type open gear lubricant
These products began to appear in the 1980s, using high-viscosity mineral-based base oils or synthetic base oils, while using polymer thickening, with excellent compounding additives and solid lubricating materials to improve the oil film thickness and boundary of the oil. Lubrication protection.
Features:
●There will be no accumulation at the root of the gear, and the oil film will not break under high impact load;
● Since the base oil and polymer do not separate, long-term stable use can be guaranteed.
For example, Great Wall brand Weiwei gear lubricants belong to this type of product, which can be applied to both oil pool lubrication and spray lubrication.
4. High viscosity synthetic products
These products began to appear in the 1990s, using very high viscosity synthetic base oils, such as PAO and polyol esters, blended with extreme pressure anti-wear agents, anti-rust and anti-corrosion agents, can also be added to some solid lubrication Materials, these products have very good oxidation resistance, thermal stability, and excellent low temperature fluidity. However, the price of such products is too high and is currently only suitable for special occasions.
