Problems solved by technology

CN1727458A discloses a worm gear oil composition, which contains at least 1% sulfurized isobutylene to improve the extreme pressure performance of the lubricating oil, but because the sulfurized olefin contains too much active sulfur (S content reaches 40%), it will affect the copper worm gear. Causes severe corrosion and reduces pitting of gears

preparation example Construction

[0035] The preparation method of the worm gear oil composition provided by the present invention includes: according to the viscosity grade of the composition, one or more polyether oils are added in proportion to a container with stirring, and then the above additive components are added in proportion, and then Stir at 20-60°C until uniform and transparent.

[0036] In the worm gear and worm oil composition provided by the present invention, the extreme pressure and antiwear agent of B component contained does not contain sulfur element, will not cause corrosion to the copper worm gear, and at the same time has better performance than the extreme pressure and antiwear agent containing sulfur. Excellent extreme pressure performance prevents the tooth surface from being scratched, sintered, worn, etc. In addition, component B can also reduce the friction coefficient of lubricating oil, greatly reducing the energy loss caused by transmission friction. It is suitable for copper-c...

Abstract

The invention provides a worm and gear oil composition and a preparation method thereof. The worm and gear oil composition comprises at least one polyether base oil, at least one extreme-pressure anti-wear agent, at least one oiliness agent or friction modifier, at least one antioxidant of amine, phenolic or a mixture of the two, at least one metal deactivator, at least one demulsifier, and at least one anti-foam agent, wherein the viscosity of the polyether base oil at 40 DEG C is 40mm<2> / s-680mm<2> / s according to measurement with GB / T265, and the extreme-pressure anti-wear agent comprises phosphate amine salt with a specific structure. The worm and gear oil composition provided by the invention has an excellent extreme-pressure anti-wear property, causes no corrosion to non-ferrous metals and particularly copper, and has excellent high-temperature detergency, oxidation stability, lubricating oil properties and viscosity-temperature properties, a simple preparation method and a wide application range.

Description

technical field [0001] The invention relates to a lubricating oil composition, more precisely a clean type worm gear oil composition which is non-corrosive to metal. Background technique [0002] Worm lubricating oil has a decisive influence on worm gear transmission. It can reduce friction, reduce wear, reduce temperature rise, and improve worm gear transmission efficiency and service life. Since the worm gear pair is usually matched with bronze, brass worm gear and steel worm gear, the additives of the worm gear oil should meet the special requirements of the steel-copper friction pair: it must have good extreme pressure resistance and wear reduction. Grinding performance, but also does not corrode copper. Copper is very sensitive to sulfur and chlorine, so it is not suitable to use sulfur and chlorine extreme pressure agents with high chemical activity to avoid chemical corrosion and pitting on the tooth surface. This is also the biggest difference between worm gear oil ...
