Description
Technical field
The present invention relates to a kind of synthesis type open type gear oil composition.
Background technology
In the industries such as cement, metallurgy, mining industry, electric power, open type gear driving application is very general, is particularly applied on some oversized rotating equipments, as masher, drying machine, mine power shovel, coal mill, ball mill etc.Trace it to its cause, mainly in production technique, it well can adapt to a large amount of needs ventilated in apparatus for rotating, and this is that closed-type gear transmission is incomparable.Open type gear driving bring adverse influence with contacting all can to the occlusion of gear due to himself physical construction feature and transport characteristics.Germany Wollhofen once investigated the source of damage of 55 cover exposed drive gears, concluded: 18.2% causes due to insufficient lubrication and lubrication failure.It can thus be appreciated that the good and bad importance run well for protection open gears of lubricant properties, a good exposed gear lubricating agent should have following characteristic: 1. good adhesivity; 2. good viscosity-temperature characteristics; 3. good low-temperature fluidity; 4. good water resisting property and rust-preventing characteristic; 5. good extreme pressure and antiwear behavior; 6. be easy to use.
Large-scale exposed gear conventional lubricant used is pitch lubricant.This lubricant utilizes pitch to make thickening material, has good adhesivity and oil film strength.Namely the common open gear lubricatng of 1# ~ 4# that domestic orchid refining is produced belongs to this bituminous matter lubricant; Also having a kind of is be added with the bituminous matter exposed gear lubricating agent that extreme-pressure anti-friction additive belongs to extreme pressure type, can meet the specification requirement of EP type exposed gear lubricating agent in AGMA 251.02, as patent CN 1594517A a kind of exposed gear oil of reporting.Above-mentioned 2 kinds of bituminous matter gear lubricants often need heating to be coated with in use, sometimes in order to need easy to use add about 10% volatile solvent cut after use, but this is unfavorable to environment protection.In use, also there are some serious problems in this kind of bituminous matter lubricant: (1) viscosity temperature characteristic is poor.Use temperature scope is narrower, be difficult under low temperature be added to and use position, and easily peel off, there is crack performance, especially very inconvenience is used in the occasion that variation of ambient temperature is larger, when using for spirit thinned type pitch lubricant, viscosity is difficult to control, as solidification even appears in solvent evaporation, as the blocking adopting mist lubrication then easily to cause fog system.(2) contamination resistance is poor, very easily infiltrates impurity and the extremely difficult sedimentation of contamination particle, causes the abrasive wear of gear.
Along with the development of science and technology and the needs of environmental protection, the agent of non-solvent non-bituminous type exposed gear becomes the major demands in market, mainly comprises the agent of tackiness exposed gear lubricating and the agent of synthesis type exposed gear lubricating.So that its good lubricity, contamination resistance be strong etc., advantage becomes one of leading product of exposed gear equipment lubrication to tackiness lubricant.This lubricant consists of tackifier, mineral oil or synthesis hydrocarbon, additive, solid lubricant substantially, as a kind of open type gear oil composition of patent CN 1962835A report, a kind of open type gear oil composition of patent CN 1962836A report.Solid lubricant tool in tackiness lubricant plays a very important role, there are some researches show solid lubricant dispersion suspension in lubricating oil, both can play the performance of solid lubricant itself, the shortcoming that frictional coefficient is large and thermal conductivity is bad of solid lubricant can have been made up again.But owing to adopting the solid additive of black, in use not easily Real-Time Monitoring is carried out to gear surface, also inconvenience is brought to maintenance.
The agent of synthesis type exposed gear lubricating has the incomparable high-performance of traditional exposed gear agent, usually adopt high viscosity synthetic base oil and additive formulated.Natural high viscosity index (HVI) mixes unique additive system makes the agent of synthesis type exposed gear have remarkable heat and oxidation susceptibility, good low-temperature fluidity, under extreme high-temperature and cold operation condition, even for the gear run with very low speed, still there is remarkable lubricity, be specially adapted to the operating mode of low speed, heavy duty, high temperature.As a kind of open gear lubricatng composition and method of making the same that patent CN 102776056A reports, adopt high viscosity synthetic base oil, synthesizing ester oil, additive formulated, there is excellent high and low temperature performance, excellent extreme pressure property, good corrosion resistance, but because its viscosity grade is low, some super-huge exposed gear equipment are applied limited.
