Abstract
The invention provides a lubricating oil composition for a gear, which comprises the following components in percentage by weight: 95 to 99% of polyalkylene glycol, 0.1 to 3.0% of antioxidant, 0.01 to 0 .5% of metal deactivator, 0.1 to 3.0% of corrosion inhibitor, 0.5 to 5.0% of extreme pressure antiwear agent and 5 to 500ppm of anti-foaming agent. The polyalkylene glycol has a structure shown in a formula I, wherein R1, R2, R3, and R4 is hydroxyl, alkyl having 1 to 12 hydrogen or carbon atoms, and acyl, and at least one of R3 and R4 is a hydrogen atom; and x and y are integers, and satisfy the relation that x+y is greater than or equal to 5 but smaller than or equal to 100, and x/(x+y) is greater than or equal to 0.5 or y/(x+y) is greater than or equal to 0.5. The lubricating oil composition for the gear provided by the invention has the advantages of excellent viscosity-temperature properties, high viscosity index, low condensation point, high flash point and high water dissolubility, and when being mixed with 20% of water, the lubricating oil composition still has good lubricity. Formula I is shown in the accompanying figure.
Description
Technical field
The present invention relates to the lubricating oil field, be specifically related to a kind of lubricant for gears composition and method of making the same.
Background technology
Gear oil is as main take mineral base oil or synthetic base oil, add a kind of important lubricating oil that the modulation of extreme pressure anti-wear additives and oiliness improver forms, be used for various wheel gearings, to prevent tooth surface abrasion, scratch, sintering etc., prolong its work-ing life, improve transmitted power efficient, reduce power loss.Gear oil should have good wear-resistant, withstand load performance and suitable viscosity.In addition, even also should have good thermal oxidation stability, anti-bubble, water separable performance energy and rustless property synthetic gear oil under very high service temperature and load, can guarantee that still all parts of transmission system is not frayed.
Often because poor sealing causes the water coolant seepage in oiling system, cause emulsification of lubricant to go bad in the industrial production, stop up oil circuit, being forced to more, oil change moves to guarantee to produce normally.Existing gear oil addresses this problem the method for system's water inlet raising demulsibilities that adopt more, perhaps oil product is changed.Can solve temporarily water inlet to the impact of gear oil although improve demulsibility, the additive in the gear oil usually reduces gradually along with the separation of water.The existence of a small amount of moisture still easily causes lubrication failure.Directly gear oil is changed the use cost that has increased again enterprise.
Summary of the invention
