Problems solved by technology

[0005] Although bituminous gear oil is a traditional oil, it also has some shortcomings in its application: such as poor viscosity-temperature performance, easy to become brittle in winter, easy to peel off from the gear, causing wear; Cause coking or cracking of the lubricant; when spray lubrication is used, it is easy to cause blockage of the spray system; poor anti-pollution ability, easy to absorb and retain dirt, resulting in abrasive wear of gears; uneven distribution on the tooth surface, oil change cumbersome; solvent volatilization can easily cause air pollution and safety hazards, etc.
[0011] Judging from the existing situation, although open gears have a wide range of uses in modern industry, the lubrication of open gears is not paid enough attention

Embodiment 1

[0061] The open gear oil composition includes: 64.3% mineral oil base oil, 30% polyisobutylene, 4% sulfurized isobutylene, 1% phosphonate, 0.1% amine and ethylene oxide condensate (T1001, purchased from Hongze, Jiangsu Province Peng Petroleum Additive Co., Ltd.), 0.5% benzotriazole, and 0.1% polymethicone oil, the contents are all percentages by weight.

[0062] Among them, the mineral oil base oil is 150BS, and the viscosity at 100°C is 32.3mm 2 / s base oil, purchased from Taiwan.

[0063] The preparation method is as follows: After mixing the components at 45°C for 3 hours, analyze and test the viscosity, viscosity index, anti-foaming performance, anti-emulsification performance and other items, and the finished product is obtained after passing the test.

[0064] After testing, it belongs to 150 grade open gear oil, and the specific performance test results are shown in Table 2.

Embodiment 2

[0069] The open gear oil composition includes: 40.9% polyalphaolefin synthetic base oil (PAO-100), 50% OCP, 3% sodium salt of phosphorothioate double ester amine, 2% phosphonate, 3% sulfurized phosphoric acid Molybdenum, 500ppm ethylene glycol ester, 1% phosphate ester, 500ppm simethicone.

[0070] The preparation method is as follows: After mixing the components at 50°C for 4 hours, analyze and test the viscosity, viscosity index, anti-foaming performance, anti-emulsifying performance and other items, then add the friction modifier sulfur molybdenum thiophosphate, and then adjust for 2 hours That is the finished product.

[0071] After testing, it belongs to 320 grade open gear oil, and the specific performance test results are shown in Table 3.

Abstract

The invention discloses an open gear oil composition, which comprises the following parts: 10-70% thickener, 0.1-5% extreme-pressure antiwear agent, 0.005-0.5% anti-emulsifier and mineral oil typed and or synthetic basic oil. The invention improves open gear oil viscosity-temperature property, which modifies oil stability and reserving property.

Description

technical field [0001] The invention relates to a lubricating oil composition, in particular to a lubricating oil composition used in an open gear transmission system, and belongs to the technical field of lubricating oil additives. Background technique [0002] With the development of science and technology, the quality requirements of lubricants for mechanical equipment are getting higher and higher. Some lubricant products have corresponding technical standards. In my country's industrial production, most of the transmission and speed change in various mechanical operating equipment use gear devices. Generally, the lubricating oil used to lubricate gear transmissions including worm gears is called gear oil. Gear oil can be divided into open gear oil, industrial closed gear oil and vehicle gear oil and other types. Among them, open gear oil is used for the lubrication of gears operating under exposed conditions to prolong their service life. It is mostly used in the lub...
